    Focus in this discussion of the Central African Republic is on: geography; the people; history and political conditions; government; the economy; foreign relations; and relations with the US. The population of the Central African Republic totaled 2.7 million in 1985 with an annual growth rate of 2.8%. The infant mortality rate is 134/1000 with life expectancy at 49 years. The Central African Republic is at almost the precise center of Africa, about 640 km from the nearest ocean. More than 70% of the population live in rural areas. There are more than 80 ethnic groups, each with its own language. The precolonial history of the area was marked by successive waves of migration, of which little is known. These migrations are responsible for the complex ethnic and linguistic patterns today. United with Chad in 1906, it formed the Oubangui-Chari-Chad colony. In 1910, it became 1 of the 4 territories of the Federation of French Equatorial Africa, along with Chad, Congo, and Gabon. After World War II, the French Constitution of 1946 inaugurated the first of a series of reforms that led eventually to complete independence for all French territories in western and equatorial Africa. The nation became an autonomous republic within the newly established French Community on December 1, 1958, and acceded to complete independence as the Central Africa Republic on August 13, 1960. The government is made up of the executive and the judicial branches. The constitution and legislature remain suspended. All executive and legislative powers, as well as judicial oversight, are vested in the chief of state. The Central African Republic is 1 of the world's least developed countries, with an annual per capita income of $310. 85% of the population is engaged in subsistence farming. Diamonds account for nearly 1/3 of export earnings; the industrial sector is limited. The US terminated bilateral assistance programs in 1979, due to the human rights violations of the Bokassa regime, but modest

    The Central African Republic contains 242,000 square miles, which rolling terrain almost 2000 feet above sea level. The climate is tropical, and it has a population of 2.8 million people with a 2.5% growth rate. There are more than 80 ethnic groups including Baya 34%, Banda 28%, Sara 10%, Mandja 9%, Mboum 9%, and M'Baka 7%. The religions are traditional African 35%, protestant 25%, Roman Catholic 25%, and Muslim 15%, and the languages are French and Sangho. The infant mortality rate is 143/1000, with expectancy at 49 years and a 40% literacy rate. The work force of 1 million is 70% agricultural, industry 6% and commerce and service 6% and government 3%. The government consists of a president assisted by cabinet ministers and a single party. Natural resources include diamonds, uranium, timber, gold, and oil, and major industries are beverages, textiles, and soap. Agricultural products feature coffee, cotton, peanuts, tobacco, food crops and livestock. Most of the population live in rural areas and most of the 80 ethnic groups have their own language. This is one of the world's least developed countries, with a per capita income of $375/year. The main problems with development are the poor transportation infrastructure, and the weak internal and international marketing systems. The US and various international organizations have aided in agriculture development, health programs, and family planning. US investment is mainly in diamond and gold mining, and although oil drilling has been successful it is not economically feasible at current prices.

    Chikungunya virus (CHIKV) is an alphavirus transmitted by the bite of mosquito vectors. Over the past 10 years, the virus has gained mutations that enhance its transmissibility by the Aedes albopictus vector, resulting in massive outbreaks in the Indian Ocean, Asia and Central Africa. Recent introduction of competent A. albopictus vectors into the Central African Republic (CAR) pose a threat of a Chikungunya fever (CHIKF) epidemic in this region. We undertook this study to assess the genetic diversity and background of CHIKV strains isolated in the CAR between 1975 and 1984 and also to estimate the ability of local strains to adapt to A. albopictus. Our results suggest that, local CHIKV strains have a genetic background compatible with quick adaptation to A. albopictus, as previously observed in other Central African countries. Intense surveillance of the human and vector populations is necessary to prevent or anticipate the emergence of a massive CHIKF epidemic in the CAR.

    The many constraints and psychologically demanding situations to which French soldiers are subjected (living conditions, operational pace, scenes of exaction, hostile crowds, combat situations) have justified a psychiatrist being posted to the theatre of operation Sangaris, in the Central African Republic, soon after the military intervention began. While the psychiatrist's activity is typical of psychiatry in operational situations,.the configuration of the conflict- a civil war - and its impact on the psyche of the soldiers making up the task force have resulted in these practices being adapted and acknowledgement of the need to update skills.

    The wildlife populations of northern Central African Republic (CAR) have long suffered intense uncontrolled hunting. Socio-political turmoil in northern CAR that started in 2002 resulted in a rebellion in 2006. An aerial sample count was carried out in northern CAR after the ceasefire to assess the impact of this troubled period on wildlife. The survey was flown at the end of the dry season in February-March 2010. It covered a landscape complex of 95,000 km² comprising national parks, hunting reserves and community hunting areas. Comparison with earlier surveys revealed a dramatic decline of wildlife: the numbers of large mammals fell by 94% in 30 years, probably due to poaching, loss of habitat and diseases brought by illegal movements of cattle. Elephant (Loxodonta africana), Reduncinae and topi (Damaliscus lunatus) populations showed the greatest decline (each over 90%). Other species declined by 70-80% during the same period. The future of wildlife in this area is dark without a strong commitment to provide adequate funding and quickly implement of determined field management. Reinforced cooperation with neighbouring Chad and Sudan is required since they are facing similar problems.

    Full Text Available Abstract Background Yaws is a bacterial skin and bone infectious disease caused by Treponema pallidum pertenue. It is endemic, particularly among pygmies in Central African Republic. To assess the clinical cure rate after treatment with benzathinepenicillin in this population, we conducted a cohort survey of 243 patients in the Lobaye region. Findings and conclusion The rate of healing of lesions after 5 months was 95.9%. This relatively satisfactory level of therapeutic response implies that yaws could be controlled in the Central African Republic. Thus, reinforcement of the management of new cases and of contacts is suggested.

    A study using bipyramid tetse fly traps in the Nola-Bilolo sleeping sickness focus (Central African Republic) reveals ecological and behavioural differences between two vectors, Glossina palpalis palpalis and G. fuscipes fuscipes. The latter species inhabits mainly open water sites and surrounding forest, whereas G. p. palpalis occurs mainly in coffe plantations near villages. Consequently, the man-fly contact differs considerably according to the species. The intensity of trypanosomiasis transmission, estimated by the probable distribution of cases, showed significant positive correlation with the density of the flies. Analysis of the fly blood meals in two villages show that, unlike G. g. palpalis, G. f. fuscipes feeds on men more than on pigs. Trypanosoma vivax infection was observed only in G. fuscipes fuscipes. The differences in occupation of the environment between the two vectors must be taken in account in trapping programmes which may modify this distribution.

    The Central African Republic is one of the world's most vulnerable countries, suffering from chronic poverty, violent conflicts and weak disaster resilience. In collaboration with Doctors without Borders/Médecins Sans Frontières (MSF), this study presents a novel approach to collect information about socio-economic vulnerabilities related to malnutrition, access to resources and coping capacities. The first technical test was carried out in the North of the country (sub-prefecture Kabo) in May 2015. All activities were aimed at the investigation of technical feasibility, not at operational data collection, which requires a random sampling strategy. At the core of the study is an open-source Android application named SATIDA COLLECT that facilitates rapid and simple data collection. All assessments were carried out by local MSF staff after they had been trained for one day. Once a mobile network is available, all assessments can easily be uploaded to a database for further processing and trend analysis via MSF in-house software. On one hand, regularly updated food security assessments can complement traditional large-scale surveys, whose completion can take up to eight months. Ideally, this leads to a gain in time for disaster logistics. On the other hand, recording the location of every assessment via the smart phones' GPS receiver helps to analyze and display the coupling between drought risk and impacts over many years. Although the current situation in the Central African Republic is mostly related to violent conflict it is necessary to consider information about drought risk, because climatic shocks can further disrupt the already vulnerable system. SATIDA COLLECT can easily be adapted to local conditions or other applications, such as the evaluation of vaccination campaigns. Most importantly, it facilitates the standardized collection of information without pen and paper, as well as straightforward sharing of collected data with the MSF headquarters or other

    Background Rift Valley fever virus (RVFV) causes a viral zoonosis, with discontinuous epizootics and sporadic epidemics, essentially in East Africa. Infection with this virus causes severe illness and abortion in sheep, goats, and cattle as well as other domestic animals. Humans can also be exposed through close contact with infectious tissues or by bites from infected mosquitoes, primarily of the Aedes and Culex genuses. Although the cycle of RVFV infection in savannah regions is well documented, its distribution in forest areas in central Africa has been poorly investigated. Methodology/Principal Findings To evaluate current circulation of RVFV among livestock and humans living in the Central African Republic (CAR), blood samples were collected from sheep, cattle, and goats and from people at risk, such as stock breeders and workers in slaughterhouses and livestock markets. The samples were tested for anti-RVFV immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies. We also sequenced the complete genomes of two local strains, one isolated in 1969 from mosquitoes and one isolated in 1985 from humans living in forested areas. The 1271 animals sampled comprised 727 cattle, 325 sheep, and 219 goats at three sites. The overall seroprevalence of anti-RVFV IgM antibodies was 1.9% and that of IgG antibodies was 8.6%. IgM antibodies were found only during the rainy season, but the frequency of IgG antibodies did not differ significantly by season. No evidence of recent RVFV infection was found in 335 people considered at risk; however, 16.7% had evidence of past infection. Comparison of the nucleotide sequences of the strains isolated in the CAR with those isolated in other African countries showed that they belonged to the East/Central African cluster. Conclusion and significance This study confirms current circulation of RVFV in CAR. Further studies are needed to determine the potential vectors involved and the virus reservoirs. PMID:27760144

    In early 1996, 481 women visiting the antenatal services of the 3 major governmental health centres in the capital city of the Central African Republic (CAR) were included in the study. All study participants underwent the health centre's routine gynaecological examination, including laboratory diagnosis of trichomoniasis, candidiasis, gonorrhoea, syphilis and bacterial vaginosis. Cervical secretions and blood samples from study participants were sent to the National STD Reference Centre for diagnosis of Chlamydia trachomatis, Neisseria gonorrhoeae, Candida albicans, Treponema pallidum, and HIV. Overall, 34% of the study women were diagnosed with at least one sexually transmitted infection (STI) (3.1% N. gonorrhoeae, 6.2% C. trachomatis, 9.9% T. vaginalis, 6.7% T. pallidum, 12.2% HIV-1). In addition, 29.1% of women were diagnosed with bacterial vaginosis and 46.6% with candidiasis. Only a small proportion of these women had sought treatment during the weeks before, despite the recognition of genital symptoms. Self-reported and health worker-recognized symptoms, signs and laboratory results exhibited only low sensitivities, specificities, and positive predictive values in the diagnosis of STIs. These findings confirm the high vulnerability of young African women to STIs and emphasize the need for specific control interventions which should include affordable and user-friendly services. Moreover, these results call for more effective quality control in case of laboratory-based STI control strategies and question the validity of syndromic STI management strategies in women attending antenatal care services in Africa.

    A coprologic study of free-ranging western lowland gorillas (Gorilla gorilla gorilla) at Bai Hokou, Dzangha-Ndoki National Park, Central African Republic (2 degrees 51'34''N, 16 degrees 28'03''E) was conducted from October 1999 to November 2000. All 75 fecal samples examined were positive for endoparasites, and each contained at least two species. Parasites present included two genera of amoebae, entodiniomorph ciliates, including Prototapirella gorillae, Troglodytella spp., and Gorillophilus thoracatus, a Balantidium-like organism, strongyle/trichostrongyle eggs (including a presumptive Mammomonogamus sp. and several other genera), Strongyloides sp., Probstmayria sp., a spirurid, a trichuroid, and several unidentified trematodes. Flagellates and cestodes were not found. Despite the presence of a variety of parasite genera, in general, levels of parasitism were low. These data provide baseline parasitologic data for this population as part of a comprehensive health-monitoring program. With the advent of ecotourism in this study area, continued monitoring is indicated for insuring the health of both gorillas and humans in the Bai Hokou study area.

    The city of Bangui, the capital of the Central African Republic, is located on the right bank of the Ubangi River which is the northernmost tributary of the Congo River. From its foundation in 1889 this city has always suffered from serious problems of water management. This is related to the specificity of the site configuration (steep hills surrounding a large swampy flat valley poorly drained) and to the urbanisation process responsible for the waterproofing of soils and the associated increased runoff processes under tropical humid condition.This paper presents the results of a geochemical and isotopic survey carried out in 2011 aiming at evaluating the type and chemical quality of the groundwater resources of the Bangui region. By combining geological, hydrogeochemical and isotopic data it appears that the underground of Bangui seems favourable to the development of a secured and sustainable water supply from groundwater provided that the conditions of exploitation would be constrained by the local authorities. The deep fractured (and locally kastified) Precambrian carbonate aquifers known as Bimbo and Fatima formations are identified as target resources considering the relatively good quality of the resource from the chemical point of view, and the semi-confined structure of the aquifer preventing the mixing with shallow aquifers already strongly impacted by domestic and industrial pollutions.

    A serological study of toxoplasmosis was conducted between 1996 and 1998 on 1953 patients of the Medical Analysis Laboratory of the Institut Pasteur de Bangui. The mean age of patients was 28 years. Among sera tested by ELISA, seropositivity to IgG antibodies was observed in 50.6%, and 2.6% sera were found positive for IgM antitoxoplasma antibodies (immuno-capture). The seroprevalence did not vary significantly according to sex or age. The results showed 40.8% sera had IgG antibodies titered 400 Ul/ml and more. The proportion of high level (> 400 Ul) IgG was more important in males than in females. High level IgG antibodies were statistically significant more frequently in the sera of females aged 10-29 years. Of the procreative women, 49.1% were at risk of contacting toxoplasmosis. The diagnosis of recently acquired infection, based on the coexistence of IgM antibodies and high level IgG antibodies, was noted in 1.6% among sera of procreative women. In the Central African Republic, serologic survey during pregnancy is not systematic and HIV seroprevalence is high (15%). Risks of acute infections during pregnancy and of opportunistic infections in HIV-infection patients are high. A control of toxoplasmosis is justifiable (screening during pregnancy, sanitary education) in CAR.

  5. Surveillance of Canine Rabies in the Central African Republic: Impact on Human Health and Molecular Epidemiology.

    Full Text Available Although rabies represents an important public health threat, it is still a neglected disease in Asia and Africa where it causes tens of thousands of deaths annually despite available human and animal vaccines. In the Central African Republic (CAR, an endemic country for rabies, this disease remains poorly investigated.To evaluate the extent of the threat that rabies poses in the CAR, we analyzed data for 2012 from the National Reference Laboratory for Rabies, where laboratory confirmation was performed by immunofluorescence and PCR for both animal and human suspected cases, and data from the only anti-rabies dispensary of the country and only place where post-exposure prophylaxis (PEP is available. Both are located in Bangui, the capital of the CAR. For positive samples, a portion of the N gene was amplified and sequenced to determine the molecular epidemiology of circulating strains.In 2012, 966 exposed persons visited the anti-rabies dispensary and 632 received a post-exposure rabies vaccination. More than 90% of the exposed persons were from Bangui and its suburbs and almost 60% of them were under 15-years of age. No rabies-related human death was confirmed. Of the 82 samples from suspected rabid dogs tested, 69 were confirmed positive. Most of the rabid dogs were owned although unvaccinated. There was a strong spatiotemporal correlation within Bangui and within the country between reported human exposures and detection of rabid dogs (P<0.001. Phylogenetic analysis indicated that three variants belonging to Africa I and II lineages actively circulated in 2012.These data indicate that canine rabies was endemic in the CAR in 2012 and had a detrimental impact on human health as shown by the hundreds of exposed persons who received PEP. Implementation of effective public health interventions including mass dog vaccination and improvement of the surveillance and the access to PEP are urgently needed in this country.

    The management of severe malaria is a major challenge in the health care services in sub-Saharan Africa. This study aimed to assess the efficacy and safety of artemether and quinine in severe malaria at Complexe pédiatrique of Bangui, Central African Republic. A total of 212 children among 1125 hospital admissions (18.8%), and aged 6 to 59 months were randomly treated with artemether and quinine. Anemia (58.5%) and seizures (33.5%) were the major syndromes observed. On the third day of follow up, a regression of clinical signs and parasite clearance were observed in 98.1% of children treated with artemether and 97.1% of children treated with quinine. The death rate was 2.3% due to anemic and neurological forms. These findings show that the artemether and quinine have similar efficacy. Hence, associated with adequate intensive health care, the use of these antimalarial drugs can significantly reduce mortality from severe malaria in the Central African Republic.

    The hydrogeology of the Cretaceous sandstone formations of Carnot-Berbérati (covering an area of 46.000 km2) in the western part of the central African Republic is poorly known. In order to improve the access of local populations to a clean and safe drinking water resource, new investigations have been carried out in order to characterize groundwater in terms of quality, origin, residence time and sustainability. Two sampling campaigns were organized in August 2014 (rainy period) and April 2015 (dry period) on respectively 31 and 43 points including boreholes, wells and river waters. Conventional hydrogeochemical tools in conjunction with isotope hydrology tools were used to evaluate the water types and the anthropogenic fingerprint on groundwater, their recharge processes and the flow organization scheme. Investigations have shown the existence of interesting amounts of groundwater within what seems a single, well hydraulically connected unconfined aquifer of max. 400m thick. Groundwaters are characterized by two main water types: CaMg-HCO3 (for deep boreholes and river waters) and CaMg-ClNO3 (shallow wells). The latter clearly showing the very strong influence of anthropogenic activities (washing, dumps, latrines) in the near vicinity of wells and boreholes used for the drinking water supply. This is also highlighting the total lack of protection zone around the wells and boreholes. Stable isotopes of the water molecule (18O and 2H) are in agreement with a local recharge of groundwater and show a relatively homogeneous composition within the whole aquifer system. Tritium data indicate a modern recharge with a high renewability potential for shallow groundwater but very low tritium levels are observed in the deepest boreholes indicating the probable occurrence of complex flow conditions within the system in some sectors. From these results and because of its extension and storage potential, the Carnot-Berbérati sandstone aquifer appears as a groundwater resource

  10. Emergence of quinolone resistance among extended-spectrum beta-lactamase-producing Enterobacteriaceae in the Central African Republic: genetic characterization

    Full Text Available Abstract Background Cross-resistance to quinolones and beta-lactams is frequent in Enterobacteriaceae, due to the wide use of these antibiotics clinically and in the food industry. Prescription of one of these categories of antibiotic may consequently select for bacteria resistant to both categories. Genetic mechanisms of resistance may be secondary to a chromosomal mutation located in quinolone resistance determining region of DNA gyrase or topoisomerase IV or to a plasmid acquisition. The insertion sequence ISCR1 is often associated with qnr and may favour its dissemination in Gram-negative bacteria. The aim of this study was to determine the genetic mechanism of quinolone resistance among extended-spectrum beta-lactamase-producing Enterobacteriaceae strains in the Central African Republic. Findings Among seventeen ESBL-producing Enterobacteriaceae isolated from urine, pus or stool between January 2003 and October 2005 in the Central African Republic, nine were resistant to ciprofloxacin (seven from community patients and two from hospitalized patients. The ESBL were previously characterized as CTX-M-15 and SHV-12. Susceptibility to nalidixic acid, norfloxacin and ciprofloxacin, and the minimal inhibitory concentrations of these drugs were determined by disc diffusion and agar dilution methods, respectively. The presence of plasmid-borne ISCR1-qnrA region was determined by PCR and amplicons, if any, were sent for sequencing. Quinolone resistance determining region of DNA gyrase gyrA gene was amplified by PCR and then sequenced for mutation characterization. We found that all CTX-M-producing strains were resistant to the tested quinolones. All the isolates had the same nucleotide mutation at codon 83 of gyrA. Two Escherichia coli strains with the highest MICs were shown to harbour an ISCR1-qnrA1 sequence. This genetic association might favour dissemination of resistance to quinolone and perhaps other antibiotics among Enterobacteriaceae

    The molecular epidemiology of hepatitis C virus (HCV) in the Central African Republic (CAR) is poorly documented. Thus, we conducted phylogenetic analyses of NS5B gene sequences from 58 HCV-infected inhabitants of a remote area of south-west CAR, which indicated that 48 (82.8%) were infected with genotype 4 (HCV-4), five (8.6%) with genotype 2 and five (8.6%) with genotype 1. HCV-4 strains were highly heterogeneous, containing previously described subtypes 4k (48%), 4c (27%), 4r (4%), 4f (4%) and unclassified subtypes (17%). To estimate the epidemic history of these HCV-4 strains, an evolutionary analysis using the coalescent approach was used. The estimated date of the most recent common ancestor of the CAR HCV-4 strains was 1539 (95% confidence intervals, 1317-1697). They exhibited a rapid, exponential spread from 1935 to 1965, simultaneously with what was recently reported in neighbouring Cameroon and Gabon. The hypothesis of a massive iatrogenic transmission during interventions for the control of endemic tropical diseases is discussed.

    Full Text Available Abstract Background Measuring human rights violations is particularly challenging during or after armed conflict. A recent nationwide survey in the Central African Republic produced estimates of rates of grave violations against children and adults affected by armed conflict, using an approach known as the "Neighborhood Method". Methods In June and July, 2009, a random household survey was conducted based on population estimates from the 2003 national census. Clusters were assigned systematically proportional to population size. Respondents in randomly selected households were interviewed regarding incidents of killing, intentional injury, recruitment into armed groups, abduction, sexual abuse and rape between January 1, 2008 and the date of interview, occurring in their homes' and those of their three closest neighbors. Results Sixty of the selected 69 clusters were surveyed. In total, 599 women were interviewed about events in 2,370 households representing 13,669 persons. Estimates of annual rates of each violation occurring per 1000 people in each of two strata are provided for children between the ages of five and 17, adults 18 years of age and older and the entire population five years and older, along with a combined and weighted national rate. The national rates for children age five to 17 were estimated to be 0.98/1000/year (95% CI: 0.18 - 1.78 for recruitment, 2.56/1000/year (95% CI: 1.50 - 3.62 for abduction, 1.13/1000/year (95% CI: 0.33 - 1.93 for intentional injury, 10.72/1000 girls/year (95% CI: 7.40 - 14.04 for rape, and 4.80/1000 girls/year (95% CI: 2.61 - 6.00 for sexual abuse. No reports of any violation against a person under the age of five were recorded and there were no reports of rape or sexual abuse of males. No children were reported to have been killed during the recall period. Rape and abduction were the most frequently reported events. Conclusions The population-based figures greatly augment existing information on

    Basile Kamgang

    Full Text Available The invasive Asian tiger mosquito Aedes albopictus (Diptera: Culicidae was first reported in central Africa in 2000, in Cameroon, with the indigenous mosquito species Ae. aegypti (Diptera: Culicidae. Today, this invasive species is present in almost all countries of the region, including the Central African Republic (CAR, where it was first recorded in 2009. As invasive species of mosquitoes can affect the distribution of native species, resulting in new patterns of vectors and concomitant risk for disease, we undertook a comparative study early and late in the wet season in the capital and the main cities of CAR to document infestation and the ecological preferences of the two species. In addition, we determined the probable geographical origin of invasive populations of Ae. albopictus with two mitochondrial DNA genes, COI and ND5. Analysis revealed that Ae. aegypti was more abundant earlier in the wet season and Ae. albopictus in the late wet season. Used tyres were the most heavily colonized productive larval habitats for both species in both seasons. The invasive species Ae. albopictus predominated over the resident species at all sites in which the two species were sympatric. Mitochondrial DNA analysis revealed broad low genetic diversity, confirming recent introduction of Ae. albopictus in CAR. Phylogeographical analysis based on COI polymorphism indicated that the Ae. albopictus haplotype in the CAR population segregated into two lineages, suggesting multiple sources of Ae. albopictus. These data may have important implications for vector control strategies in central Africa.

    Breast cancer is recognized as a major public health problem in developing countries; however, there is very little evidence of behavioral factors associated with breast cancer risk. This study was conducted to identify lifestyles as risk factors for breast cancer among Central African women. A case-control study was conducted with 174 cases confirmed histologically by the pathology unit of the National Laboratory and 348 age-matched controls. Data collection tools included a questionnaire with interviews and medical records of patients. Data were analyzed using SPSS software version 20. Odd ratio (OR) and 95% confidence intervals (95% CI) were obtained by unconditional logistic regression. In total, 522 women were studied with a mean age of 45.8 (SD = 13.4) years. By unconditional logistic regression model, women with breast cancer were more likely to have attained illiterate and elementary education level [11.23 (95% CI, 4.65–27.14) and 2.40 (95% CI, 1.15–4.99)], married [2.09 (95% CI, 1.18–3.71)], positive family history [2.31 (95% CI, 1.36–3.91)], radiation exposure [8.21 (95% CI, 5.04–13.38)], consumption charcuterie [10.82 (95% CI, 2.39–48.90)], fresh fish consumption [4.26 (95% CI, 1.56–11.65)], groundnut consumption [6.46 (95% CI, 2.57–16.27)], soybean consumption [16.74 (95% CI, 8.03–39.84)], alcohol [2.53 (95% CI, 1.39–4.60)], habit of keeping money in bras[3.57 (95% CI, 2.24–5.69)], overweight [5.36 (95% CI, 4.46–24.57)] and obesity [3.11(95% CI, 2.39–20.42)]. However, decreased risk of breast cancer was associated with being employed [0.32 (95% CI, 0.19–0.56)], urban residence [0.16 (95% CI, 0.07–0.37)], groundnut oil consumption [0.05 (95% CI, 0.02–0.14)], wine consumption [0.16 (95% CI, 0.09–0.26)], non habit of keeping cell phone in bras [0.56 (95% CI, 0.35–0.89)] and physical activity [0.71(95% CI, 0.14–0.84)].

    Gorilla tourism, widely perceived as a lucrative industry, is propelled by strong market demand with programs in five countries and for three of four gorilla subspecies. Human presence may negatively affect wild gorillas, potentially lowering immunity and increasing the likelihood of acquiring human-borne disease. Yet, behavioral impacts of humans on wild gorilla behavior remain largely unexplored, particularly for western lowland gorillas. We evaluate the impact of tourist presence, human observer numbers (tourists, trackers, and researchers), and human observer distance on the behavior of one habituated gorilla group at Bai Hokou, Central African Republic. Behavioral data were collected for more than 12 months from January 2007. Of silverback aggressive events, 39% (N=229) were human directed, but 65% were low-level soft barks. Adult females, and one in particular, were responsible for the highest number of aggressive events toward humans. Humans maintained closer proximity to the silverback when tourists were present, although tourist numbers had no significant impact on overall group activity budgets or rates of human-directed aggression. However, as research team size increased, group feeding rates decreased. Close observer-silverback distance correlated with a decrease in his feeding rates and an increase in human monitoring. He directed less aggression toward observers at distances >10 m, although observers spent 48.5% of time between 6 and 10 m of the silverback. We discuss gorilla personality as a factor in human-directed aggression. We explore whether the current 7 m distance limit governing gorilla tourism, based on disease transmission risks, is sufficient considering the potential behavioral stressor of close human presence. We recommend increasing minimum observation distance to >10 m where possible, decreasing observer group sizes, particularly after a visit consisting of maximum numbers and restricting tourist access to 1 visit/day.

    Full Text Available In Sub-Saharan Africa, infectious diarrhea is a major cause of morbidity and mortality. A case-control study was conducted to identify the etiology of diarrhea and to describe its main epidemiologic risk factors among hospitalized children under five years old in Bangui, Central African Republic.All consecutive children under five years old hospitalized for diarrhea in the Pediatric Complex of Bangui for whom a parent's written consent was provided were included. Controls matched by age, sex and neighborhood of residence of each case were included. For both cases and controls, demographic, socio-economic and anthropometric data were recorded. Stool samples were collected to identify enteropathogens at enrollment. Clinical examination data and blood samples were collected only for cases.A total of 333 cases and 333 controls was recruited between December 2011 and November 2013. The mean age of cases was 12.9 months, and 56% were male. The mean delay between the onset of first symptoms and hospital admission was 3.7 days. Blood was detected in 5% of stool samples from cases. Cases were significantly more severely or moderately malnourished than controls. One of the sought-for pathogens was identified in 78% and 40% of cases and controls, respectively. Most attributable cases of hospitalized diarrhea were due to rotavirus, with an attributable fraction of 39%. Four other pathogens were associated with hospitalized diarrhea: Shigella/EIEC, Cryptosporidium parvum/hominis, astrovirus and norovirus with attributable fraction of 9%, 10%, 7% and 7% respectively. Giardia intestinalis was found in more controls than cases, with a protective fraction of 6%.Rotavirus, norovirus, astrovirus, Shigella/EIEC, Cryptosporidium parvum/hominis were found to be positively associated with severe diarrhea: while Giardia intestinalis was found negatively associated. Most attributable episodes of severe diarrhea were associated with rotavirus, highlighting the urgent

    Good drug prescription and distribution practices are pre-requisites for rational use of essential generic medications. However few studies have been conducted on this topic in sub-Saharan Africa especially in rural areas. The purpose of this study in the Mambéré-Kadei health district of the Central African Republic was to evaluate drug use patterns with special attention to prescribing and dispensing, as a basis for assisting policy makers in planning and identifying intervention strategies. The transverse descriptive survey was undertaken in 14 public health facilities in the Mambéré-Kadéï health district. Data were collected by interviewing care providers and patients immediately after consultation and at the exit of the dispensary. The indicators recommended by the World Health Organization (WHO) for investigating drug use patterns in Communities were used for data collection. A total of 512 prescriptions were analysed. The average number of drugs prescribed per consultation was 3.5. Most drugs (68.6%) were prescribed by generic name. Antibiotic use (31.4% of consultations) was frequent and 29% of patients received injections. 82.1% of the drugs were compliant with the national essential drug list. The distribution survey showed that 79.46% of prescriptions were completely filled. No serious distribution errors occurred but 21.5% of the dispensed drugs were inadequately labelled. Patients understood the modalities of use for 69.6% of prescribed drugs. The average consultation and distribution times were 8.3 and 5 minutes respectively. Excessive use of antibiotics and injections and blunderbuss therapy is still observed in Mambéré-Kadei. Many drugs not included on the essential drug list and non-generics are prescribed. Other prescription and distribution problems identified in this survey include poor information on drug use, inadequate labelling of dispensed drugs, and lack of access to standard drug use tools such as a locally adapted essential drug

    Full Text Available Drug resistance to Plasmodium falciparum contributes to major health problems in central Africa and, as a consequence, poverty. We have analyzed the efficacy of three currently available antimalarial drugs to treat symptomatic, uncomplicated P. falciparum malaria in semiimmune adults living in Bangui, Central Republic of Africa. 210 consecutive individuals were enrolled in the survey, of which 45 were excluded. Those having received dihydroartemisin proved significantly less parasitemic than those having received quinine per os or sulfadoxin-pyrimethamin (χ2 = 16.93 ; p < 0.05, and 75 % recovered in two days compared to 57 and 44 %, respectively. The 25 % who did not recover benefited from a second cure with dihydroartemisin, which proved 100 % efficient. The most accurate protocol remains to be established by analyzing clinical and parasitological data and taking into account the economics of the country.

    Full Text Available This paper uses nonlinear unit root testing procedures to examine the issue of inflation convergence for the Central African Economic and Monetary Community (CEMAC member states including Cameron, Central African Republic, Chad, Equatorial Guinea, Gabon and the Republic of Congo. The results from nonlinear STAR unit root tests suggest that inflation differentials for the sample countries are nonlinear and mean reverting processes. These results provide evidence of inflation convergence among countries within CEMAC. The finding of inflation convergence indicates the feasibility of a common monetary policy and/or inflation targeting regime within CEMAC.

    Full Text Available BACKGROUND: Infectious diseases pose one of the greatest threats to endangered species, and a risk of gastrointestinal parasite transmission from humans to wildlife has always been considered as a major concern of tourism. Increased anthropogenic impact on primate populations may result in general changes in communities of their parasites, and also in a direct exchange of parasites between humans and primates. AIMS: To evaluate the impact of close contact with humans on the occurrence of potentially zoonotic protists in great apes, we conducted a long-term monitoring of microsporidia, Cryptosporidium and Giardia infections in western lowland gorillas at different stages of the habituation process, humans, and other wildlife in Dzanga-Sangha Protected Areas in the Central African Republic. RESULTS: We detected Encephalitozoon cuniculi genotypes I and II (7.5%, Enterocytozoon bieneusi genotype D and three novel genotypes (gorilla 1-3 (4.0%, Giardia intestinalis subgroup A II (2.0% and Cryptosporidium bovis (0.5% in gorillas, whereas in humans we found only G. intestinalis subgroup A II (2.1%. In other wild and domestic animals we recorded E. cuniculi genotypes I and II (2.1%, G. intestinalis assemblage E (0.5% and C. muris TS03 (0.5%. CONCLUSION: Due to the non-specificity of E. cuniculi genotypes we conclude that detection of the exact source of E. cuniculi infection is problematic. As Giardia intestinalis was recorded primarily in gorilla groups with closer human contact, we suggest that human-gorilla transmission has occurred. We call attention to a potentially negative impact of habituation on selected pathogens which might occur as a result of the more frequent presence of humans in the vicinity of both gorillas under habituation and habituated gorillas, rather than as a consequence of the close contact with humans, which might be a more traditional assumption. We encourage to observe the sections concerning hygiene from the IUCN best

    Past climate change caused severe disturbances of the Central African rainforest belt, with forest fragmentation and re-expansion due to drier and wetter climate conditions. Besides climate, human induced forest degradation affected biodiversity, structure and carbon storage of Congo basin rainforests. Information on climatically stable, mature rainforest, unaffected by human induced disturbances, provides means of assessing the impact of forest degradation and may serve as benchmarks of carbon carrying capacity over regions with similar site and climate conditions. BioGeoChemical (BGC) ecosystem models explicitly consider the impacts of site and climate conditions and may assess benchmark levels over regions devoid of undisturbed conditions. We will present a BGC-model validation for the Western Congolian Lowland Rainforest (WCLRF) using field data from a recently confirmed forest refuge, show model - data comparisons for disturbed und undisturbed forests under different site and climate conditions as well as for sites with repeated assessment of biodiversity and standing biomass during recovery from intensive exploitation. We will present climatic thresholds for WCLRF stability, analyse the relationship between resilience, standing C-stocks and change in climate and finally provide evidence of hysteresis.

    Full Text Available Introduction. The number of Salmonella isolated from clinical samples that are resistant to multiple antibiotics has increased worldwide. The aim of this study was to determine the prevalence of resistant Salmonella enterica isolated in Bangui. Methods. All enteric Salmonella strains isolated from patients in 2008 were identified and serotyped, and the phenotypes of resistance were determined by using the disk diffusion method. Nine resistance-associated genes, blaTEM, blaOXA, blaSHV, tetA, aadA1, catA1, dhfrA1, sul I, and sul II, were sought by genic amplification in seven S.e. Typhimurium strains. Results. The 94 strains isolated consisted of 47 S.e. Typhimurium (50%, 21 S.e. Stanleyville (22%, 18 S.e. Enteritidis (19%, 4 S.e. Dublin (4%, 4 S.e. Hadar (4%, and 1 S.e. Papuana (1%. Twenty-five (28% were multiresistant, including 20 of the Typhimurium serovar (80%. Two main phenotypes of resistance were found: four antibiotics (56% and to five antibiotics (40%. One S.e. Typhimurium isolate produced an extended-spectrum β-lactamase (ESBL. Only seven strains of S.e. Typhimurium could be amplified genically. Only phenotypic resistance to tetracycline and aminosides was found. Conclusion. S. Typhimurium is the predominant serovar of enteric S. enterica and is the most widely resistant. The search for resistance genes showed heterogeneity of the circulating strains.

    Outbreaks of African swine fever (ASF) have been reported from many countries, particularly in Sub-Saharan Africa, but until 2007 the disease had never been reported from the Republic of Mauritius. This is the first report describing field epidemiological and laboratory investigations into the outbreak of the lethal pig disease on the island. The official index case displayed clinical and necropsy signs suggestive of ASF. Serological and agent identification methods used to confirm and investigate the outbreak yielded negative and a few positive results respectively. Phylogenetic analysis based on DNA sequencing clustered the outbreak strain within genotype II viruses. The outbreak was controlled by modified stamping out and risk assessment revealed the possibility of disease endemicity in the country.

    Full Text Available Abstract Background Glossina palpalis palpalis (Diptera: Glossinidae is widespread in west Africa, and is the main vector of sleeping sickness in Cameroon as well as in the Bas Congo Province of the Democratic Republic of Congo. However, little is known on the structure of its populations. We investigated G. p. palpalis population genetic structure in five sleeping sickness foci (four in Cameroon, one in Democratic Republic of Congo using eight microsatellite DNA markers. Results A strong isolation by distance explains most of the population structure observed in our sampling sites of Cameroon and DRC. The populations here are composed of panmictic subpopulations occupying fairly wide zones with a very strong isolation by distance. Effective population sizes are probably between 20 and 300 individuals and if we assume densities between 120 and 2000 individuals per km2, dispersal distance between reproducing adults and their parents extends between 60 and 300 meters. Conclusions This first investigation of population genetic structure of G. p. palpalis in Central Africa has evidenced random mating subpopulations over fairly large areas and is thus at variance with that found in West African populations of G. p. palpalis. This study brings new information on the isolation by distance at a macrogeographic scale which in turn brings useful information on how to organise regional tsetse control. Future investigations should be directed at temporal sampling to have more accurate measures of demographic parameters in order to help vector control decision.

    Full Text Available In this paper I analyze the impact of the Eurasian Union on the Central Asian republics, with a focus on remittances trends. To this end I review at first the literature regarding the effects of the Customs Union on its members. Then, I assess the current state of the economies most likely to be affected by membership in the Eurasian Union, i.e. Tajikistan and Kyrgyzstan, whose specificity is their dependency on remittances. Secondly, I present a plausible scenario in regard to the influence of the formalization of this regional organization on the emerging Central Asian regional security subcomplex. I argue that the EEU is a hindrance towards the five Central Asian Republics’ evolving towards a regional security complex. Not only has it already distorted trade in the region, but it can also turn some presently frozen conflicts into security hotspots. I hold that the only way to spur development in the region is, internally, to diversify the economy, and, externally, to bring the five republics closer. I try to show that the Central Asian Republics should simultaneously pursue a switch from a balance of threat to regional integration and sustainable national development. Nonetheless, the EEU will have at best mixed effects when it comes to these necessities. Alternatively, China and the New Silk Road initiative that it endorses might contribute to de-securitizing some of the existing issues.

    Background In high income countries, low socioeconomic status (SES) is related to unhealthier dietary patterns, while evidence on the social patterning of diet in low and middle income countries is scarce. Objective In this study, we assess dietary patterns in the general population of a middle income country in the African region, the Republic of Seychelles, and examine their distribution according to educational level and income. Methods Data was drawn from two independent national surveys conducted in the Seychelles among adults aged 25–64 years in 2004 (n = 1236) and 2013 (n = 1240). Dietary patterns were assessed by principal component analysis (PCA). Educational level and income were used as SES indicators. Data from both surveys were combined as no interaction was found between SES and year. Results Three dietary patterns were identified: “snacks and drinks”, “fruit and vegetables” and “fish and rice”. No significant associations were found between SES and the “snacks and drinks” pattern. Low vs. high SES individuals had lower adherence to the “fruit and vegetables” pattern [prevalence ratio (95% CI) 0.71 (0.60–0.83)] but a higher adherence to the traditional “fish and rice” pattern [1.58 (1.32–1.88)]. Income modified the association between education and the “fish and rice” pattern (p = 0.02), whereby low income individuals had a higher adherence to this pattern in both educational groups. Conclusion Low SES individuals have a lower consumption of fruit and vegetables, but a higher consumption of traditional foods like fish and rice. The Seychelles may be at a degenerative diseases stage of the nutrition transition. PMID:27214139

    Pygmy populations occupy a vast territory extending west-to-east along the central African belt from the Congo Basin to Lake Victoria. However, their numbers and actual distribution is not known precisely. Here, we undertake this task by using locational data and population sizes for an unprecedented number of known Pygmy camps and settlements (n = 654) in five of the nine countries where currently distributed. With these data we develop spatial distribution models based on the favourability function, which distinguish areas with favourable environmental conditions from those less suitable for Pygmy presence. Highly favourable areas were significantly explained by presence of tropical forests, and by lower human pressure variables. For documented Pygmy settlements, we use the relationship between observed population sizes and predicted favourability values to estimate the total Pygmy population throughout Central Africa. We estimate that around 920,000 Pygmies (over 60% in DRC) is possible within favourable forest areas in Central Africa. We argue that fragmentation of the existing Pygmy populations, alongside pressure from extractive industries and sometimes conflict with conservation areas, endanger their future. There is an urgent need to inform policies that can mitigate against future external threats to these indigenous peoples' culture and lifestyles.

    2016-02-01

    Full Text Available This paper presents the most relevant aspects of the academic debate on smart power, in order to apply this concept to analyze the foreign policy of the Republic of China on Latin America and the Caribbean, but especially to Central America; where the dispute between China and Taiwan for international recognition is evident. It is argued that the smart power of China to Central America is expressed in the attractiveness of having privileged access to the Chinese market and its funding programs and official development assistance. While this country has a large presence in Latin America and the Caribbean, in Central America such influence is counteracted in the light of the close relationship that all Central American countries except Costa Rica, maintain with Taiwan. Based on the development of China as a world power, it is expected that this condition changed, so that this country would increase its influence in Central America.

    Full Text Available Aim: to describe the pattern of skin diseases among refugees attending the dermatology clinic in refugee camps in southern Chad. Methods: A descriptive clinic-based cross-sectional study was done in two refugee camps of people from Republic of Central Africa in Southern Chad. Diagnosis of skin diseases was done through clinical examination by a single dermatologist along with the help of hand lens provided with illumination. Lack of investigations and other skin diagnostic tools prevented further confirmation of diagnosis. Data was manually analyzed and diagnosis was presented as number and percent using the ICD -10 of the World Health Organization. Results: A total of 366 dermatologic diseases were diagnosed in 361 patients. Certain infectious and parasitic diseases and dermatitis/ eczema were the commonest diagnostic categories (39.9% and 22.45; respectively followed by disorders of skin appendices (15% and infections of skin and subcutaneous tissues (13.1%. Tinea barbae /capitis, ringworm and impetigo are the commonest recorded infections (11.5%, 10.1% and 7.9%; respectively. Miliaria and acne vulgaris were the most frequent disorders of skin appendages. Conclusions: Infectious skin diseases are common among refugees. There are urgent needs for health education and promotion of personal hygiene with adequate sanitation as well as availability of diagnostic tests [TAF Prev Med Bull 2015; 14(4.000: 324-328

    Full Text Available The paper deals with expert predictions on the development of e-learning in the Czech Republic, a country in Central Europe. The first part of the paper describes the development of e-learning with specific feature in the Czech Republic in relation to the implementation of Information and communication technologies (ICT to schools and the business sector. The second part of the paper presents a survey with selected experts, conducted in the years 2012 and 2013 in the Czech Republic, aiming at identifying the trends of e-learning. Special attention is paid to applying e-learning in the corporate sector. Our survey provides a better understanding of the current and future trends of e-learning to a wide range of stakeholders interested in using e-learning. Understanding the existing and future state of e-learning should be a starting point for further development of any e-learning strategy, in both education and corporate sectors. Therefore, the findings of our survey have important practical implications. The survey also proves that identification of the e-learning trends at the national level is influenced by political, economic, social and technological factors.

  4. Multiresolution quantification of deciduousness in West Central African forests

    Full Text Available The characterization of leaf phenology in tropical forests is of major importance and improves our understanding of earth-atmosphere-climate interactions. The availability of satellite optical data with a high temporal resolution has permitted the identification of unexpected phenological cycles, particularly over the Amazon region. A primary issue in these studies is the relationship between the optical reflectance of pixels of 1 km or more in size and ground information of limited spatial extent. In this paper, we demonstrate that optical data with high to very-high spatial resolution can help bridge this scale gap by providing snapshots of the canopy that allow discernment of the leaf-phenological stage of trees and the proportions of leaved crowns within the canopy. We also propose applications for broad-scale forest characterization and mapping in West Central Africa over an area of 141 000 km2. Eleven years of the Moderate Resolution Imaging Spectroradiometer (MODIS Enhanced Vegetation Index (EVI data were averaged over the wet and dry seasons to provide a dataset of optimal radiometric quality at a spatial resolution of 250 m. Sample areas covered at a very-high (GeoEye and high (SPOT-5 spatial resolution were used to identify forest types and to quantify the proportion of leaved trees in the canopy. The dry season EVI was positively correlated with the proportion of leaved trees in the canopy. This relationship allowed the conversion of EVI into canopy deciduousness at the regional level. On this basis, ecologically important forest types could be mapped, including young secondary, open Marantaceae, Gilbertiodendron dewevrei and swamp forests. We show that in west central African forests, a large share of the variability in canopy reflectance, as captured by the EVI, is due to variation in the proportion of leaved trees in the upper canopy, thereby opening new perspectives for biodiversity and carbon-cycle applications.

    Underground storage systems are currently being used worldwide for the geological storage of natural gas (CH4), the geological disposal of CO2, in geothermal energy, or radioactive waste disposal. We introduce a complex approach to the risks posed by induced bedrock instabilities in deep geological underground storage sites. Bedrock instability owing to underground openings has been studied and discussed for many years. The Bohemian Massif in the Czech Republic (Central Europe) is geologically and tectonically complex. However, this setting is ideal for learning about the instability state of rock masses. Longterm geological and mining studies, natural and induced seismicity, radon emanations, and granite properties as potential storage sites for disposal of radioactive waste in the Czech Republic have provided useful information. In addition, the Czech Republic, with an average concentration radon of 140 Bq m-3, has the highest average radon concentrations in the world. Bedrock instabilities might emerge from microscale features, such as grain size and mineral orientation, and microfracturing. Any underground storage facility construction has to consider the stored substance and the geological settings. In the Czech Republic, granites and granitoids are the best underground storage sites. Microcrack networks and migration properties are rock specific and vary considerably. Moreover, the matrix porosity also affects the mechanical properties of the rocks. Any underground storage site has to be selected carefully. The authors suggest to study the complex set of parameters from micro to macroscale for a particular place and type of rock to ensure that the storage remains safe and stable during construction, operation, and after closure.

    Full Text Available Pseudomonas aeruginosa (PA has a non-clonal, epidemic population with a few widely distributed and frequently encountered sequence types (STs called 'high-risk clusters'. Clinical P. aeruginosa (clinPA has been studied in all inhabited continents excepted in Africa, where a very few isolates have been analyzed. Here, we characterized a collection of clinPA isolates from four countries of West and Central Africa.184 non-redundant isolates of clinPA from hospitals of Senegal, Ivory Coast, Nigeria, and Central African Republic were genotyped by MLST. We assessed their resistance level to antibiotics by agar diffusion and identified the extended-spectrum β-lactamases (ESBLs and metallo-β-lactamases (MBLs by sequencing. The population structure of the species was determined by a nucleotide-based analysis of the entire PA MLST database and further localized on the phylogenetic tree (i the sequence types (STs of the present collection, (ii the STs by continents, (iii ESBL- and MBL-producing STs from the MLST database.We found 80 distinct STs, of which 24 had no relationship with any known STs. 'High-risk' international clonal complexes (CC155, CC244, CC235 were frequently found in West and Central Africa. The five VIM-2-producing isolates belonged to CC233 and CC244. GES-1 and GES-9 enzymes were produced by one CC235 and one ST1469 isolate, respectively. We showed the spread of 'high-risk' international clonal complexes, often described as multidrug-resistant on other continents, with a fully susceptible phenotype. The MBL- and ESBL-producing STs were scattered throughout the phylogenetic tree and our data suggest a poor association between a continent and a specific phylogroup.ESBL- and MBL-encoding genes are borne by both successful international clonal complexes and distinct local STs in clinPA of West and Central Africa. Furthermore, our data suggest that the spread of a ST could be either due to its antibiotic resistance or to features

    2015-08-01

    Full Text Available This paper looks at the issue of ethnic identity of the Dungans – descendants of early Chinese migrants in Central Asia – and its change and preservation in the context of the fragile social fabric of the Central Asian states that were born from the shadow of the now-defunct Soviet Union, the arduous processes of nation-building plagued by often violent, competing emergent nationalisms as well as political and economic turbulence, and the impact brought by the emergence of the xinyimin (Chinese new migrants. These Chinese-speaking Dungans staying in compact communities mostly in Kazakhstan, Kyrgyzstan and Uzbekistan are descendants of political and war refugees from China’s provinces of Shaanxi and Gansu who moved across the border into the territory of Czarist Russia in the later part of the nineteenth century after the crushing of the Northwest Uprising by the Imperial Ch’ing (the Manchu dynasty army which bordered on genocide and ethnic cleansing. This paper analyses how a new ethnic identity has since emerged due partly to the geographical isolation imposed by the formidable natural barrier of the Tianshan (“Heavenly Mountains” However, their Chinese language in the form of a mixture of the Shaanxi and Gansu regionalects, remarkably written today not in Chinese characters but in the Cyrillic alphabet, and Chinese traditions of the Shaanxi and Gansu varieties have been fiercely preserved through the generations until today, including nineteenth-century vocabulary and traditions which are no longer found in modern China, due both to the cohesiveness of communal life and an aversion to marriage outside the community. After analysing the community’s dilemmas of identity preservation and identity creation, this paper then proceeds to look at the impact of the disintegration of the Soviet Union in 1991 resulting in the birth of the post-Soviet independent Central Asian republics, and the influx of the xinyimin from China since the

    Granulite-facies metamorphism is extensively reported in Late Neoproterozoic/Early Palaeozoic time during formation of the East-African-Antarctic orogen (EAAO). Metamorphic data acquired from the Pan-African orogen of central Dronning Maud Land (cDML) are compared with data from northern Mozambique. The metamorphic rocks of cDML are characterised by Opx±Grt-bearing gneisses and Sil+Kfs-bearing metapelites which indicate medium-P granulite-facies metamorphism. Peak conditions, which are estimated to 800-900ºC at pressures up to 1.0 GPa, were followed by near-isothermal decompression during late Pan-African extension and exhumation. Granulite-facies lithologies are widespread in northern Mozambique, and Grt+Cpx-bearing assemblages show that high-P granulite-facies conditions with PT reaching 1.55 GPa and 900ºC were reached during the Pan-African orogeny. Garnet is replaced by symplectites of Pl+Opx+Mag indicating isothermal decompression, and the subsequent formation of Pl+amphibole-coronas suggests cooling into amphibolite facies. It is concluded that high-T metamorphism was pervasive in EAAO in Late Neoproterozoic/Early Paleozoic time, strongly overprinting evidences of earlier metamorphic assemblages.

    On April 23, 2016, the Democratic Republic of the Congo's (DRC's) Ministry of Health declared a yellow fever outbreak. As of May 24, 2016, approximately 90% of suspected yellow fever cases (n = 459) and deaths (45) were reported in a single province, Kongo Central Province, that borders Angola, where a large yellow fever outbreak had begun in December 2015. Two yellow fever mass vaccination campaigns were conducted in Kongo Central Province during May 25-June 7, 2016 and August 17-28, 2016. In June 2016, the DRC Ministry of Health requested assistance from CDC to control the outbreak. As of August 18, 2016, a total of 410 suspected yellow fever cases and 42 deaths were reported in Kongo Central Province. Thirty seven of the 393 specimens tested in the laboratory were confirmed as positive for yellow fever virus (local outbreak threshold is one laboratory-confirmed case of yellow fever). Although not well-documented for this outbreak, malaria, viral hepatitis, and typhoid fever are common differential diagnoses among suspected yellow fever cases in this region. Other possible diagnoses include Zika, West Nile, or dengue viruses; however, no laboratory-confirmed cases of these viruses were reported. Thirty five of the 37 cases of yellow fever were imported from Angola. Two-thirds of confirmed cases occurred in persons who crossed the DRC-Angola border at one market city on the DRC side, where ≤40,000 travelers cross the border each week on market day. Strategies to improve coordination between health surveillance and cross-border trade activities at land borders and to enhance laboratory and case-based surveillance and health border screening capacity are needed to prevent and control future yellow fever outbreaks.

    Large tropical trees and a few dominant species were recently identified as the main structuring elements of tropical forests. However, such result did not translate yet into quantitative approaches which are essential to understand, predict and monitor forest functions and composition over large, often poorly accessible territories. Here we show that the above-ground biomass (AGB) of the whole forest can be predicted from a few large trees and that the relationship is proved strikingly stable in 175 1-ha plots investigated across 8 sites spanning Central Africa. We designed a generic model predicting AGB with an error of 14% when based on only 5% of the stems, which points to universality in forest structural properties. For the first time in Africa, we identified some dominant species that disproportionally contribute to forest AGB with 1.5% of recorded species accounting for over 50% of the stock of AGB. Consequently, focusing on large trees and dominant species provides precise information on the whole forest stand. This offers new perspectives for understanding the functioning of tropical forests and opens new doors for the development of innovative monitoring strategies.

In other respect, there is also a dramatically rising trend in the number of natural hazards. Growing population and expansion of settlements and lifelines over hazardous areas have largely increased the impact of natural disasters both in industrialized and developing countries. Furthermore, natural disasters such as earthquakes, landslides, floods have dramatic effects on human life, infrastructures, environment, and so on. Landslides, one of the most destructive natural hazards, constitute a major geological hazard throughout the world, like in Turkey and Moldova. There are a lot of regions affected by landslides in Turkey (particularly the West, Middle and East Black Sea Region) and Moldova (e.g.: area between Nisporeni, Calarasi, Balti, Western Rezina District, Codri Hills in Central Moldova etc.), and consequences of landslides are of great importance in the two countries. In the last 50 years' period, only the economic loss due to landslides in Turkey is estimated about 5 billion , and 12.5 % of the whole settlement areas, including big and populated cities, are facing landslide threat. Similar to Turkey, there are about 16000 areas affected by landslides in Moldova. In February-March, 1998 the intensity of landslides in the central part of Moldova, including Chisinau, considerably increased. In total, 357 private households involving 1400 people were affected, 214 houses were destroyed, and 137 were damaged. The total national damage accounted for 44.3 million Lei. At present on Moldavian territory, there are more than 17000 landslides of various types. These landslides are mostly located within Central Moldavian heights, one of the most complicated geomorphologic structure and territory's fragmentation. Among major landslide triggering factors, in addition to natural ones, one should also consider the anthropogenic

    This is a false-color radar image of Central Africa, showing the Virunga Volcano chain along the borders of Rwanda, Zaire and Uganda. This area is home to the endangered mountain gorillas. This C-band L-band image was acquired on April 12, 1994, on orbit 58 of space shuttle Endeavour by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR). The area is centered at about 1.75 degrees south latitude and 29.5 degrees east longitude. The image covers an area 58 kilometers by 178 kilometers (48 miles by 178 miles). The false-color composite is created by displaying the L-band HH return in red, the L-band HV return in green and the C-band HH return in blue. The dark area in the bottom of the image is Lake Kivu, which forms the border between Zaire (to the left) and Rwanda (to the right). The airport at Goma, Zaire is shown as a dark line just above the lake in the bottom left corner of the image. Volcanic flows from the 1977 eruption of Mt. Nyiragongo are shown just north of the airport. Mt. Nyiragongo is not visible in this image because it is located just to the left of the image swath. Very fluid lava flows from the 1977 eruption killed 70 people. Mt. Nyiragongo is currently erupting (August 1994) and will be a target of observation during the second flight of SIR-C/X-SAR. The large volcano in the center of the image is Mt. Karisimbi (4,500 meters or 14,800 feet). This radar image highlights subtle differences in the vegetation and volcanic flows of the region. The faint lines shown in the purple regions are believed to be the result of agriculture terracing by the people who live in the region. The vegetation types are an important factor in the habitat of the endangered mountain gorillas. Researchers at Rutgers University in New Jersey and the Dian Fossey Gorilla Fund in London will use this data to produce vegetation maps of the area to aid in their study of the remaining 650 gorillas in the region. SIR-C was developed by NASA's Jet

    Full Text Available The Dzanga-Sangha landscape consists of a national park surrounded by production forest. It is subject to an integrated conservation and development project (ICDP. In collaboration with the ICDP personnel, a participatory model was constructed to explore wildlife conservation and industrial logging scenarios for the landscape. Three management options for the landscape′s production forest were modelled: (I ′predatory logging′, exploitation by a logging company characterised by a lack of long-term plans for staying in the landscape, (II sustainable exploitation by a certified logging company, and (III conservation concession with no commercial timber harvesting. The simulation outcomes indicate the extreme difficulties to achieve progress on either conservation or development scenarios. Both logging scenarios give best outcomes for development of the local population. However, the depletion of bushmeat under the predatory logging scenario negatively impacts the population, especially the BaAka pygmy minority who most strongly depend on hunting for their income. The model suggests that conservation and development outcomes are largely determined by the level of economic activity, both inside and outside the landscape. Large investments in the formal sector in the landscape without any measures for protecting wildlife (Scenario I leads to some species going nearly extinct, while investments in the formal sector including conservation measures (Scenario II gives best outcomes for maintaining wildlife populations. The conservation concession at simulated investment levels does not reduce poverty, defined here in terms of monetary income. Neither does it seem capable of maintaining wildlife populations since the landscape is already filled with settlers lacking economic opportunities as alternatives to poaching.

    Full Text Available Abstract Background Humans are the only host of polioviruses, thus the prospects of global polio eradication look reasonable. However, individuals with immunodeficiencies were shown to excrete vaccine derived poliovirus for long periods of time which led to reluctance to prolong the vaccination campaign for fear of this end result. Therefore, we aimed to assess the duration of excretion of poliovirus after the 2001 National Immunization Days according to Human immunodeficiency virus status. Findings Fifty three children were enrolled. Sequential stool samples were collected in between National Immunisation Days rounds and then every month during one year. Children were classified into 2 groups: no immunodepression (n = 38, immunodepression (n = 15 according to CD4+ lymphocytes cells count. Thirteen poliovirus strains were isolated from 11 children: 5 Human immunodeficiency virus positive and 6 Human immunodeficiency virus negative. None of the children excreted poliovirus for more than 4 weeks. The restriction fragment length polymorphism analysis showed that all strains were of Sabin origin including a unique Polio Sabine Vaccine types 2 and 3 (S2/S3 recombinant. Conclusions From these findings we assume that Human immunodeficiency virus positive children are not a high risk population for long term poliovirus excretion. More powerful studies are needed to confirm our findings.

    Cattle pastoralism is an important trait of African cultures. Ethnographic studies describe the central role played by domestic cattle within many societies, highlighting its social and ideological value well beyond its mere function as 'walking larder'. Historical depth of this African legacy has been repeatedly assessed in an archaeological perspective, mostly emphasizing a continental vision. Nevertheless, in-depth site-specific studies, with a few exceptions, are lacking. Despite the long tradition of a multi-disciplinary approach to the analysis of pastoral systems in Africa, rarely do early and middle Holocene archaeological contexts feature in the same area the combination of settlement, ceremonial and rock art features so as to be multi-dimensionally explored: the Messak plateau in the Libyan central Sahara represents an outstanding exception. Known for its rich Pleistocene occupation and abundant Holocene rock art, the region, through our research, has also shown to preserve the material evidence of a complex ritual dated to the Middle Pastoral (6080-5120 BP or 5200-3800 BC). This was centred on the frequent deposition in stone monuments of disarticulated animal remains, mostly cattle. Animal burials are known also from other African contexts, but regional extent of the phenomenon, state of preservation of monuments, and associated rock art make the Messak case unique. GIS analysis, excavation data, radiocarbon dating, zooarchaeological and isotopic (Sr, C, O) analyses of animal remains, and botanical information are used to explore this highly formalized ritual and the lifeways of a pastoral community in the Holocene Sahara.

    Human African trypanosomiasis, or sleeping sickness, is caused by the protozoan parasites Trypanosoma brucei rhodesiense or Trypanosoma brucei gambiense, and is a major cause of systemic and neurological disability throughout sub-Saharan Africa. Following early-stage disease, the trypanosomes cross the blood-brain barrier to invade the central nervous system leading to the encephalitic, or late stage, infection. Treatment of human African trypanosomiasis currently relies on a limited number of highly toxic drugs, but untreated, is invariably fatal. Melarsoprol, a trivalent arsenical, is the only drug that can be used to cure both forms of the infection once the central nervous system has become involved, but unfortunately, this drug induces an extremely severe post-treatment reactive encephalopathy (PTRE) in up to 10% of treated patients, half of whom die from this complication. Since it is unlikely that any new and less toxic drug will be developed for treatment of human African trypanosomiasis in the near future, increasing attention is now being focussed on the potential use of existing compounds, either alone or in combination chemotherapy, for improved efficacy and safety. The kynurenine pathway is the major pathway in the metabolism of tryptophan. A number of the catabolites produced along this pathway show neurotoxic or neuroprotective activities, and their role in the generation of central nervous system inflammation is well documented. In the current study, Ro-61-8048, a high affinity kynurenine-3-monooxygenase inhibitor, was used to determine the effect of manipulating the kynurenine pathway in a highly reproducible mouse model of human African trypanosomiasis. It was found that Ro-61-8048 treatment had no significant effect (P = 0.4445) on the severity of the neuroinflammatory pathology in mice during the early central nervous system stage of the disease when only a low level of inflammation was present. However, a significant (P = 0.0284) reduction in

    The Central African Copperbelt (CACB) is one of the most important copper-producing regions of the world. The majority of copper produced in Africa comes from this region defined by the Neoproterozoic Katanga sedimentary basin of the southern Democratic Republic of the Congo (DRC) and northern Zambia. Copper in the CACB is mined from sediment-hosted stratabound copper deposits associated with red beds and includes the giant deposits in the Kolwezi and Tenge-Fungurume districts in the DRC and the Konkola-Musoshi and Nchanga-Chingola districts in Zambia. In recent years, sediment-hosted structurally controlled replacement and vein (SCRV) copper deposits, such as the giant Kansanshi deposit in Zambia have become important exploration targets in the CACB region.

    Full Text Available Genus Rosa L. is one of most critical taxa within European flora. Majority works is devoted to phylogeny, taxonomy and nomenclature of roses. Investigations of morphology and ecology of roses are still relatively few in number. The aim of this study was to evaluate seed mass and seed yield of six rose species (Rosa cinnamomea, R. spinosissima, R. rugosa, R. rubiginosa, R. glauca and R. canina from populations in Central Russia (Republic of Mordovia. As a result of the study, it was revealed that Rosa rugosa has maximal num-ber of seeds per rosehip among all investigated roses. Roses from section Caninae are characterized by large number of achenes per rosehip too. In contrast, among all investigated species, Rosa cinnamomea have most minimal seed yield. Origin of Rosa spinosissima population in Ruzaevka district (Republic of Mordovia, Central Russia was proposed as uncertain according to number of seeds per rosehip. At first time, the seed mass of Rosa cinnamomea, R. glauca and R. rubiginosa was revealed.

    The relation between academic race stereotype endorsement and academic self-concept was examined in two studies of seventh- and eighth-grade African Americans. Based on expectancy-value theory, the authors hypothesized that academic race stereotype endorsement would be negatively related to self-perceptions. Furthermore, it was anticipated that the relation between stereotype endorsement and self-perceptions would be moderated by racial centrality. The hypothesis was supported in two independent samples. Among students with high racial centrality, endorsement of traditional race stereotypes was linked to lower self-perceptions of academic competence. The stereotype/self-concept relation was nonsignificant among youth for whom race was less central to their identities. These results confirm the supposition of expectancy-value theory and illustrate the interweaving of group and individual identity with motivational beliefs.

  7. Organization of central database for implementation of ionizing radiation protection in the Republic of Croatia

    The paper is intended to give an overview of the situation in the Republic of Croatia resulting from passing of the new ionizing radiation protection law. Data collecting organization and records keeping structure will be highlighted in particular, as well as data exchange between individual services involved in ionizing radiation protection. The Radiation Protection Act has been prepared in compliance with the international standards and Croatian regulations governing the ionizing radiation protection field. Its enforcement shall probably commence in October 1999, when the necessary bylaws regulating in detail numerous specific and technical issues of particular importance for ionizing radiation protection implementation are expected to be adopted. Within the Croatian Government, the Ministry of Health is charge of ionizing radiation protection. Such competence is traditional in our country and common throughout the world. This Ministry has authorized three institutions to carry out technical tasks related to the radiation protection, such as radiation sources inspections and personal dosimetry. Such distribution of work demands coordination of all involved institutions, control of their work and records keeping. The Croatian Radiation Protection Institute has been entrusted to coordinate work of these institutions, control their activities, and set up the central national registry of radiation sources and workers, as well as doses received by the staff during their work. Since the Croatian Radiation Protection Institute is a newly established institution, we could freely determine our operational framework. Due to its publicly accessible source code and wide base of users and developers, the best prospective for stability and long-term accessibility is offered by the Linux operating system. For the database development, Oracle RDBMS was used, partly because it is a leading manufacturer of database management systems, and partly because our staff is very familiar

    Full Text Available Five rocket (Eruca sativa (L. Mill. varieties and accessions were cultivated under field conditions in the Czech Republic (Central Europe and subsequently studied for variation in morphology and yield. Two cultivation techniques (treatments were tested during the growing seasons in 2010 and 2011: directly sown seeds in the field and plantlets cultivated in a glasshouse and later transplanted to the field. There were analysed four morphological parameters of the leaf rosette (leaf shape in outline, leaf margin, leaf apex and leaf colour, marketable yield, nonmarketable parts, and rosette radius. Plants from plantlets transplanted to the field in spring terms (April yielded a substantially higher marketable yield and had a higher rosette radius in contrast to plants from directly sown seeds. Conversely, for the summer terms (late August, September the direct sowing technique produced higher marketable yield in comparison with plantlets treatment. Plants cultivated from directly sowed seeds reached a marketable yield on average from 15 to 60 g per plant while transplanted plants produced on average from 10 to 49 g per plant. It is evident that cultivation of rocket under field conditions of the Czech Republic is possible and provides, when using the appropriate sowing term, more or less stable yields of marketable parts. Details on variation in yield parameters of individual varieties and accessions are presented.

    The populations of light-demanding trees that dominate the canopy of central African forests are now aging. Here, we show that the lack of regeneration of these populations began ca. 165 ya (around 1850) after major anthropogenic disturbances ceased. Since 1885, less itinerancy and disturbance in the forest has occurred because the colonial administrations concentrated people and villages along the primary communication axes. Local populations formerly gardened the forest by creating scattered openings, which were sufficiently large for the establishment of light-demanding trees. Currently, common logging operations do not create suitable openings for the regeneration of these species, whereas deforestation degrades landscapes. Using an interdisciplinary approach, which included paleoecological, archaeological, historical, and dendrological data, we highlight the long-term history of human activities across central African forests and assess the contribution of these activities to present-day forest structure and composition. The conclusions of this sobering analysis present challenges to current silvicultural practices and to those of the future. DOI: http://dx.doi.org/10.7554/eLife.20343.001 PMID:28093097

    Previous studies found that Central Equatorial Africa (CEA) has experienced a long-term drying trend over the past two decades. To further evaluate this finding, we investigate possible mechanisms for this drought by analyzing multiple sources of observations and reanalysis data. We examine the atmospheric circulation changes related to sea surface temperature (SST) variations that control the equatorial African rainfall. Our results indicate that the long-term drought during April, May and June over CEA may reflect the large-scale response of the atmosphere to tropical SST variations. Likely the drought results primarily from SST variations over Indo-Pacific associated with the enhanced and westward extended tropical Walker circulation. These are consistent with the weakened ascent over Central Africa that is associated with the reduced low-level moisture transport. The large-scale atmospheric circulation changes associated with a weaker West African monsoon also have some contribution. These results reinforce the notion that tropical SSTs have large impacts on rainfall over equatorial Africa and highlight the need to further distinguish the contribution of SSTs changes (e.g., La Niña-like pattern and Indian Ocean warming) due to natural variability and anthropogenic forcing to the drought.

    As a part of a comprehensive programme of tuberculosis (TB) control in the central prison in Qazvin, Islamic Republic of Iran, a programme of active case-finding was carried out from February 2004 to July 2005. From the 768 prisoners examined, 41 (5.3%) were suspected of TB and gave sputum samples. A total of 7 smear-positive TB cases were found, giving a TB prevalence in the prison of 910 per 100,000, 113 times the total TB prevalence in Qazvin province in the same year. From 7 diagnosed and treated patients, 4 were cured with the category 1 standard regimen, 1 completed treatment and 2 failed to complete treatment. Improvements are needed in TB case recognition of prisoners, especially newcomers.

    African swine fever (ASF) is a devastating disease of domestic pigs. It is a socioeconomically important disease, initially described from Kenya, but subsequently reported in most Sub-Saharan countries. ASF spread to Europe, South America and the Caribbean through multiple introductions which were initially eradicated—except for Sardinia—followed by re‑introduction into Europe in 2007. In this study of ASF within the Democratic Republic of the Congo, 62 domestic pig samples, collected between 2005–2012, were examined for viral DNA and sequencing at multiple loci: C-terminus of the B646L gene (p72 protein), central hypervariable region (CVR) of the B602L gene, and the E183L gene (p54 protein). Phylogenetic analyses identified three circulating genotypes: I (64.5% of samples), IX (32.3%), and XIV (3.2%). This is the first evidence of genotypes IX and XIV within this country. Examination of the CVR revealed high levels of intra-genotypic variation, with 19 identified variants. PMID:28218698

    Peter Vermeersch

    2003-04-01

    Full Text Available To what extent has the EU's growing concern for norms of minority protection influenced domestic policy-making in the candidate member states in Central Europe? In order to begin to explore this question, the present article assesses the impact of both domestic and international factors on the development of policies towards national minorities in three Central europen countries: the Czech Republic, Hungary and Poland. Following an introduction, which places the subject in the context of the larger debates on minority rights, the first part of the article describes the ways in which regional organizations in Europe have attempted to persuade or induce the three countries under consideration to adopt minority rights policies. The second section then describes policy developments in Central Europe and considers the factors that have contributed to policy shifts. Finally, the third part reflects on the uneven impact of the EU's accession criteria on the development of minority rights policies in the candidate countries and concludes that the EU's impact on policy has crucially depended both on domestic interests and receptivity to international concerns for internal security.

    Full Text Available New detailed vegetation reconstructions are proposed in Atlantic Central Africa from a modern pollen data set derived from 199 sites (Cameroon, Gabon and Congo including 131 new sites. In this study, the concept of plant functional classification is improved with new and more detailed plant functional types (PFTs and new aggregations of pollen taxa. Using the biomisation method, we reconstructed (1 modern potential biomes and (2 potential succession stages of forest regeneration, a new approach in Atlantic Central African vegetation dynamics and ecosystem functioning reconstruction. When compared to local vegetation, potential biomes are correctly reconstructed (97.5% of the sites and tropical rain forest (TRFO biome is well identified from tropical seasonal forest (TSFO biome. When the potential biomes are superimposed on the White's vegetation map, only 76.4% of the sites are correctly reconstructed. But using botanical data, correspondence and cluster analyses, the 43 sites from Congo (Mayombe evidence more affinities with those of central Gabon and so they can also be considered as correctly reconstructed as TRFO biome and White's map should be revised. In terms of potential succession stages of forest regeneration, the mature forest (TMFO is well differentiated from the secondary forest (TSFE, but inside this latter group, the young and the pioneer stages are not clearly identified due probably to their low sampling representation. Moreover, linked to their progressive and mosaic character, the boundaries between two forest biomes or two forest stages are not clearly detected and need also a more intensive sampling in such transitions.

    Full Text Available Why and how have Slovakia and the Czech Republic adopted flat tax policies? That is what this paper answers. This is a curious development given that flat tax policies were noticeably absent from the landscape of most of the world, including Eastern Europe. I argue that two simultaneous processes occur that make adoption viable.  First, at the domestic level, the idea of the flat tax is held in esteem by a number of actors, specifically: elite carriers, tax and financial ministers, think tanks and right-wing political parties. They champion this idea to its adoption, or at the least, introduce the flat tax into the policy-making apparatus. Second, at the international level, policy diffusion of the flat tax takes place. In other words, the experience of previous adopters impacts the decisions of future adopters. Examining both cognitive heuristics theory and rational learning I argue that there are “varieties of diffusion” during the diffusion of the flat tax.

    In the past ten years, elections were held in six countries of Central Africa experiencing "post-conflict" situations. The polls that took place in Burundi (2005), the Central African Republic (2005), the Democratic Republic of the Congo (2006), Congo-Brazzaville (2002, 2007), Chad (1996, 2001, 2006) and Rwanda (2003) were crucial for peace-building. In some cases, they were widely supported and supervised by the international community, being considered the last step of a peace process and t...

  3. Cross-hemispheric transport of central African biomass burning pollutants: implications for downwind ozone production

    2009-08-01

    Full Text Available Pollutant plumes with enhanced levels of trace gases and aerosols were observed over the southern coast of West Africa during August 2006 as part of the AMMA wet season field campaign. Plumes were observed both in the mid and upper troposphere. In this study we examined both the origin of these pollutant plumes and their potential to produce O3 downwind over the Atlantic Ocean. Runs using the BOLAM mesoscale model including biomass burning CO tracers were used to confirm an origin from central African fires. The plumes in the mid troposphere had significantly higher pollutant concentrations due to the fact that transport occurred from a region nearer or even over the fire region. In contrast, plumes transported into the upper troposphere over West Africa had been transported to the north-east of the fire region before being uplifted. Modelled tracer results showed that pollutants resided for between 9 and 12 days over Central Africa before being transported for 4 days, in the case of the mid-troposphere plume and 2 days in the case of the upper tropospheric plume to the measurement location over the southern part of West Africa. Around 35% of the biomass burning tracer was transported into the upper troposphere compared to that remaining in the mid troposphere. Runs using a photochemical trajectory model, CiTTyCAT, were used to estimate the net photochemical O3 production potential of these plumes. The mid tropospheric plume was still very photochemically active (up to 7 ppbv/day especially during the first few days of transport westward over the Atlantic Ocean. The upper tropospheric plume was also still photochemically active, although at a slower rate (1–2 ppbv/day. Trajectories show this plume being recirculated around an upper tropospheric anticyclone back towards the African continent (around 20° S. The potential of theses plumes to produce O3 supports the hypothesis that biomass burning pollutants are

    Chikungunya is an acute febrile illness caused by an alphavirus which is transmitted by infective Aedes mosquitoes. Two previous outbreaks of chikungunya in Malaysia were due to chikungunya virus of Asian genotype. The present outbreak involved two adjoining areas in the suburb of Ipoh city within the Kinta district of Perak, a state in the northern part of Peninsular Malaysia. Thirty seven residents in the main outbreak area and two patients in the secondary area were laboratory confirmed to be infected with the virus. The index case was a 44-year Indian man who visited Paramakudi, Tamil Naidu, India on 21st November 2006 and returned home on 30th of November 2006, and subsequently developed high fever and joint pain on the 3rd of December 2006. A number of chikungunya virus isolates were isolated from both patients and Aedes albopictus mosquitoes in the affected areas. Molecular study showed that the chikungunya virus causing the Kinta outbreak was of the Central/East African genotype which occurred for the first time in Malaysia.

  5. First early hominin from central Africa (Ishango, Democratic Republic of Congo.

    Isabelle Crevecoeur

    Full Text Available Despite uncontested evidence for fossils belonging to the early hominin genus Australopithecus in East Africa from at least 4.2 million years ago (Ma, and from Chad by 3.5 Ma, thus far there has been no convincing evidence of Australopithecus, Paranthropus or early Homo from the western (Albertine branch of the Rift Valley. Here we report the discovery of an isolated upper molar (#Ish25 from the Western Rift Valley site of Ishango in Central Africa in a derived context, overlying beds dated to between ca. 2.6 to 2.0 Ma. We used µCT imaging to compare its external and internal macro-morphology to upper molars of australopiths, and fossil and recent Homo. We show that the size and shape of the enamel-dentine junction (EDJ surface discriminate between Plio-Pleistocene and post-Lower Pleistocene hominins, and that the Ishango molar clusters with australopiths and early Homo from East and southern Africa. A reassessment of the archaeological context of the specimen is consistent with the morphological evidence and suggest that early hominins were occupying this region by at least 2 Ma.

    Full Text Available This paper examines the profiles and work tasks of officials in central and regional administration in the Czech Republic. It analyzes data from surveys among the officials of eleven ministries in 2013 (N = 1351 and fourteen regional offices in 2012 (N = 783. First, the profile of ministerial officials (MOs is compared with that of regional-level officials (ROs. In accordance with our hypotheses, on average it is found that MOs are, when compared to ROs, older, more educated and have spent more time in civil service. Th ere is also a higher proportion of men in ministries than in regional offices. On the other hand, ministerial work seems to be affected by higher levels of fluctuation than jobs in the regional offices. Second, we compare work tasks of MOs and ROs. As expected, MOs are more involved in analytical tasks and research than ROs. In contrast, ROs are more likely to implement policies or programs, direct and monitor programs or lower-level bodies, provide advice for political bodies of the region, negotiate with elected politicians, communicate with citizens and provide methodological guidance, train or lecture. Contrary to our theoretical expectations, we found a strong positive correlation between analytical and brokering tasks (communication and negotiation. We thus reject the hypothesis that analytical tasks are at odds with negotiating and communication. Instead, it is concluded that most officials are multitaskers, and it is especially so in regional offices. It is hypothesized that this might be caused by the fact that regional offices are smaller and have a lower capacity to specialize

    2012-08-01

    Full Text Available The present study has used Meteosat infrared brightness temperature images to investigate the regional and interannual variability of Central African cloudiness. Spatial and temporal variability were investigated using half–hourly data from the Meteosat-7 during June–July–August (JJA of 1998–2002. The full domain of study (1.5E–17E, 1N–15N was divided into six regions and statistics in each region were derived. Analysis of the dependence of cloud fraction to the brightness temperature threshold is explored both over land and ocean. Three diurnal cycle regimes (continental, oceanic, and coastal are depicted according to the amplitude and peak time. Over regions of relatively flat terrain, results indicate enhancement of deep convection in the afternoon followed by a gradual decrease in the night. The diurnal cycle of convection is characterised by afternoon and early evening (around 15:00–18:00 LST maxima located mainly downwind of the major mountain chains, and a more rapid nighttime decay. In terms of the harmonic amplitude, the diurnal signal shows significant regional contrast with the strongest manifestation over the Adamaoua Plateau and the weakest near the South Cameroon Plateau. This remarkable spatial dependence is clear evidence of orographic and heterogeneous land-surface impacts on convective development. Oceanic region exhibits weak activity of convective cloudiness with a maximum at noon. It is suggested that daytime heating of the land surface and moist environment may play a role in determining the spatial distribution of cloud fraction. This study further demonstrates the importance of the Cameroon coastline concavity and coastal mountains in regulating regional frequencies of convection and their initialization. The strength of the diurnal cycle of convective activity depends on mountain height, mean flow, coastal geometry.

  10. Dramatic Declines of Montane Frogs in a Central African Biodiversity Hotspot.

    Directory of Open Access Journals (Sweden)

    Mareike Hirschfeld

    Full Text Available Amphibian populations are vanishing worldwide. Declines and extinctions of many populations have been attributed to chytridiomycosis, a disease induced by the pathogenic fungus Batrachochytrium dendrobatidis (Bd. In Africa, however, changes in amphibian assemblages were typically attributed to habitat change. We conducted a retrospective study utilizing field surveys from 2004-2012 of the anuran faunas on two mountains in western Cameroon, a hotspot of African amphibian diversity. The number of species detected was negatively influenced by year, habitat degradation, and elevation, and we detected a decline of certain species. Because another study in this region revealed an emergence of Bd in 2008, we screened additional recent field-collected samples and also pre-decline preserved museum specimens for the presence of Bd supporting emergence before 2008. When comparing the years before and after Bd detection, we found significantly diminished frog species richness and abundance on both mountains after Bd emergence. Our analyses suggest that this may be the first disease-driven community-level decline in anuran biodiversity in Central Africa. The disappearance of several species known to tolerate habitat degradation, and a trend of stronger declines at higher elevations, are consistent with Bd-induced declines in other regions. Not all species decreased; populations of some species remained constant, and others increased after the emergence of Bd. This variation might be explained by species-specific differences in infection probability. Increased habitat protection and Bd-mitigation strategies are needed for sustaining diverse amphibian communities such as those on Mt. Manengouba, which contains nearly half of Cameroon's frog diversity.

    Full Text Available Aim of this research is to provide a general situation of cattle slaughtered in Cameroon, as a representative example for the Central African Sub-region. The quality and safety of beef from the abattoir of Yaoundé, the largest in Cameroon, were considered. From January 2009 to March 2012, the pre-slaughter conditions and characteristics of 1953 cattle carcasses were recorded, as well as the pH of m. longissimus thoracis 24 h after slaughter. From these carcasses, 60 were selected to represent the bulls slaughtered. The quality parameters and composition of m. longissimus thoracis were carried out. The origin of most of the cattle was the Guinea High Savannah (74.6%, and transhumance was the common production system (75.5%. Gudali (45.6%, White Fulani (33.3% and Red Mbororo (20.3% breeds were predominant. Carcass weight was affected by rearing system and cattle category, and it markedly varied during year. Considering meat quality, the fat content was low (1.2% and similar between breeds, moreover Gudali showed the toughest meat. Of the cows slaughtered, 27% were pregnant and the most common abnormal conditions encountered were ectoparasites, fatigue, lameness, fungal-like skin lesions, enlarged lymph nodes, respiratory distress, nodular lesions. More than 20% of the carcasses had some organs condemned, mainly for liver flukes (5.17%, and 1.0% of them were completely condemned due to tuberculosis, that also affected 3.28% of lungs. These data could aid authorities draw up programmes with the aim to strengthen cattle production, improve beef supply, control and prevent the observed diseases, and promote the regional trade.

    Full Text Available BACKGROUND: Glossina palpalis palpalis (G. p. palpalis is one of the principal vectors of sleeping sickness and nagana in Africa with a geographical range stretching from Liberia in West Africa to Angola in Central Africa. It inhabits tropical rain forest but has also adapted to urban settlements. We set out to standardize a long-lasting, practical and cost-effective visually attractive device that would induce the strongest landing response by G. p. palpalis for future use as an insecticide-impregnated tool in area-wide population suppression of this fly across its range. METHODOLOGY/PRINCIPAL FINDINGS: Trials were conducted in wet and dry seasons in the Ivory Coast, Cameroon, the Democratic Republic of Congo and Angola to measure the performance of traps (biconical, monoconical and pyramidal and targets of different sizes and colours, with and without chemical baits, at different population densities and under different environmental conditions. Adhesive film was used as a practical enumerator at these remote locations to compare landing efficiencies of devices. Independent of season and country, both phthalogen blue-black and blue-black-blue 1 m(2 targets covered with adhesive film proved to be as good as traps in phthalogen blue or turquoise blue for capturing G. p. palpalis. Trap efficiency varied (8-51%. There was no difference between the performance of blue-black and blue-black-blue 1 m(2 targets. Baiting with chemicals augmented the overall performance of targets relative to traps. Landings on smaller phthalogen blue-black 0.25 m(2 square targets were not significantly different from either 1 m(2 blue-black-blue or blue-black square targets. Three times more flies were captured per unit area on the smaller device. CONCLUSIONS/SIGNIFICANCE: Blue-black 0.25 m(2 cloth targets show promise as simple cost effective devices for management of G. p. palpalis as they can be used for both control when impregnated with insecticide and for

    Using statistical relationships between the composition of precipitation at eight long-term monitoring stations and emission rates of sulphur (S) and nitrogen (N) compounds, as well as industrial dust in the Czech Republic and Slovakia (Central Europe), we modelled historic pH and concentrations of sulphate (SO4(2-)), nitrate (NO3(-)), ammonium (NH4(+)), chloride (Cl(-)), base cations (BC), and bicarbonate (HCO3(-)) in bulk precipitation from 1850 to 2013. Our model suggests that concentrations of SO4(2-), NO3(-), and HCO3(-) were similar (11-16 μeq l(-1)) in 1850. Cations were dominated by NH4(+) and BC (24-27 μeq l(-1)) and precipitation pH was >5.6. The carbonate buffering system was depleted around 1920 and precipitation further acidified at an exponential rate until the 1980s, when concentrations of SO4(2-), NO3(-), Cl(-), NH4(+) and BC reached maxima of 126, 55, 16, 76, and 57 μeq l(-1), respectively, and pH decreased to 4.2. Dust emissions from industrial sources were an important source of BC. Without their contribution, pH would have decreased to 4.0 in the 1980s, and the carbonate buffering system would have been depleted already in the 1870s. Since the late 1980s, concentrations of strong acid anions and BC have decreased by 46-81% (i.e. more than in Europe on average) due to a 53-93% reduction in regional emissions of S and N compounds and dust from industrial and agricultural sources. The present composition of precipitation is similar to the late 19th century, except for NO3(-) concentrations, which are similar to those during 1926-1950. Precipitation pH now exceeds 5.0, the carbonate buffering system has been re-established, and HCO3(-) has again become (after almost a century) a significant component of precipitation chemistry.

    Full Text Available Anomaluroid rodents show interesting biogeographic and macroevolutionary patterns, although their fossil record is meager and knowledge of the natural history of extant members of the clade remains inadequate. Living anomaluroids (Anomaluridae are confined to equatorial parts of western and central Africa, but the oldest known fossil anomaluroid (Pondaungimys comes from the late middle Eocene of Myanmar. The first appearance of anomaluroids in the African fossil record coincides with the first appearances of hystricognathous rodents and anthropoid primates there. Both of the latter taxa are widely acknowledged to have originated in Asia, suggesting that anomaluroids may show a concordant biogeographic pattern. Here we describe two new taxa of African Paleogene anomaluroids from sites in the Sirt Basin of central Libya. These include a new Eocene species of the nementchamyid genus Kabirmys, which ranks among the oldest African anomaluroids recovered to date, and a new genus and species of Anomaluridae from the early Oligocene, which appears to be closely related to extant Zenkerella, the only living non-volant anomalurid. Phylogenetic analyses incorporating the new Libyan fossils suggest that anomaluroids are not specially related to Zegdoumyidae, which are the only African rodents known to antedate the first appearance of anomaluroids there. The evolution of gliding locomotion in Anomaluridae appears to conflict with traditional assessments of relationships among living anomalurid taxa. If the historically accepted division of Anomaluridae into Anomalurinae (extant and Miocene Anomalurus and Miocene Paranomalurus and Zenkerellinae (extant and Miocene Zenkerella and extant Idiurus is correct, then either gliding locomotion evolved independently in Anomalurinae and Idiurus or non-volant Zenkerella evolved from a gliding ancestor.

    During three winter seasons (2009-2011), Pb concentrations were measured in precipitation at 10 high-elevation sites in the Czech Republic, close to the borders with Austria, Germany, Poland, and Slovakia. Soluble and insoluble Pb forms were quantified in snow (vertical deposition), and rime (horizontal deposition). The objective was to compare Pb input fluxes into ecosystems via vertical and horizontal deposition, and to identify the residual Pb pollution sources in an era of rapidly decreasing industrial pollution. Lead soluble in diluted HNO3 made up 96% of total Pb deposition, with the remaining 4% Pb bound mainly in silicates. Three times higher concentrations of soluble Pb in rime than in snow, and 2.5 times higher concentrations of insoluble Pb in rime than in snow were associated with slightly different Pb isotope ratios. On average, the 206Pb/207Pb ratios in rime were higher than those in snow. Higher mean 206Pb/207Pb ratios of insoluble Pb (1.175) than in soluble Pb (1.165) may indicate an increasing role of geogenic Pb in recent atmospheric deposition. A distinct reversal to more radiogenic 206Pb/207Pb ratios in snow and rime in 2010, compared to literature data from rain-fed Sphagnum peatlands (1800-2000 A.D.), documented a recent decrease in anthropogenic Pb in the atmosphere of Central Europe. Since the early 1980s, Pb concentrations in snow decreased 18 times in the rural south of the Czech Republic, but only twice in the industrial north of the Czech Republic. Isotope signatures indicated that Pb in today's atmospheric deposition is mainly derived from Mesozoic ores mined/processed in Poland and coal combustion in the Czech Republic and Poland.

None of 10 patients whose {alpha}-gene status was determined had {alpha}-thalassemia-2. These data strongly support the concept that the {beta}{sup s} gene on chromosome 11 of these individuals is of African origin and that the {alpha}-gene locus on chromosome 16 is of white or native American origin. The clinical severity of the disease in these nonblack patients is appropriate to their haplotype without {alpha}-thalassemia-2 and is comparable with that of black patients. All persons with congenital hemolytic anemia should be examined for the presence of sickle cell disease regardless of physical appearance or ethnic background.

    Full Text Available Abstract Background Hepatitis B virus (HBV is the major cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma. The global epidemiological scenario of HBV infection has been changing rapidly over the last two decades due to an effective immunization programme initiated by the World Health Organization. The objective of this study is to estimate the prevalence of HBV in apparently healthy young people and to identify the risk factors of transmission of the HBV among this population in Bangui. Methods Dried blood Spots from 801 adolescent high school and young adult university students were prepared by spotting a drop of whole blood (4 spots from the same fingerprick onto Whatman filter paper. A blood sample aliquot eluted from DBS was then processed with commercial ELISA tests (Abbott Murex, Dartfort, UK to detect HBsAg antigen, Anti-HBc and Anti-HBs antibodies. Results The overall prevalence was 42.3% for antibody to hepatitis B core antigen, 15.5% for HBsAg of which 1.3% of HBsAg alone. HBV familial antecedents, sexual activity and socioeconomic conditions were the main risk factors of HBV infection encountered in the adolescents and young adults. Conclusion These results show for the first time the high prevalence of HBV in apparently healthy young people in Bangui. This high prevalence is age- and sex-independent. Transmission risk factors were a familial antecedent of HBV, no utilisation of condoms and public scholarship. To lower HBV prevalence, an adequate program of active screening and vaccination for adolescents and young adults should be implemented, along with a universal immunization program.

    Full Text Available Pollutant plumes with enhanced concentrations of trace gases and aerosols were observed over the southern coast of West Africa during August 2006 as part of the AMMA wet season field campaign. Plumes were observed both in the mid and upper troposphere. In this study we examined the origin of these pollutant plumes, and their potential to photochemically produce ozone (O3 downwind over the Atlantic Ocean. Their possible contribution to the Atlantic O3 maximum is also discussed. Runs using the BOLAM mesoscale model including biomass burning carbon monoxide (CO tracers were used to confirm an origin from central African biomass burning fires. The plumes measured in the mid troposphere (MT had significantly higher pollutant concentrations over West Africa compared to the upper tropospheric (UT plume. The mesoscale model reproduces these differences and the two different pathways for the plumes at different altitudes: transport to the north-east of the fire region, moist convective uplift and transport to West Africa for the upper tropospheric plume versus north-west transport over the Gulf of Guinea for the mid-tropospheric plume. Lower concentrations in the upper troposphere are mainly due to enhanced mixing during upward transport. Model simulations suggest that MT and UT plumes are 16 and 14 days old respectively when measured over West Africa. The ratio of tracer concentrations at 600 hPa and 250 hPa was estimated for 14–15 August in the region of the observed plumes and compares well with the same ratio derived from observed carbon dioxide (CO2 enhancements in both plumes. It is estimated that, for the period 1–15 August, the ratio of Biomass Burning (BB tracer concentration transported in the UT to the ones transported in the MT is 0.6 over West Africa and the equatorial South Atlantic.

    Full Text Available This paper examines the role and contribution of tourism to local economic development and in the attainment of the Millennium Development Goals one and seven dealing with extreme poverty alleviation and environmental sustainability in the biodiversity endowed Central African sub-region. The concepts of sustainable tourism development and local economic development (in sub-Saharan Africa are examined. Through field observations and semi-structured interviews with 21 tourism industry stakeholders in Cameroon, an analysis of tourism’s role and future in LED and in the attainment of the Millennium Development Goals 1 & 7 is undertaken. The core challenges presently inhibiting tourism’s development thereby limiting its contribution to local economic development and the attainment of these goals in Cameroon are identified and a framework within which tourism’s contribution can be increased is proposed.

  9. Lesula: a new species of Cercopithecus monkey endemic to the Democratic Republic of Congo and implications for conservation of Congo's central basin.

    John A Hart

    Full Text Available In June 2007, a previously undescribed monkey known locally as "lesula" was found in the forests of the middle Lomami Basin in central Democratic Republic of Congo (DRC. We describe this new species as Cercopithecus lomamiensis sp. nov., and provide data on its distribution, morphology, genetics, ecology and behavior. C. lomamiensis is restricted to the lowland rain forests of central DRC between the middle Lomami and the upper Tshuapa Rivers. Morphological and molecular data confirm that C. lomamiensis is distinct from its nearest congener, C. hamlyni, from which it is separated geographically by both the Congo (Lualaba and the Lomami Rivers. C. lomamiensis, like C. hamlyni, is semi-terrestrial with a diet containing terrestrial herbaceous vegetation. The discovery of C. lomamiensis highlights the biogeographic significance and importance for conservation of central Congo's interfluvial TL2 region, defined from the upper Tshuapa River through the Lomami Basin to the Congo (Lualaba River. The TL2 region has been found to contain a high diversity of anthropoid primates including three forms, in addition to C. lomamiensis, that are endemic to the area. We recommend the common name, lesula, for this new species, as it is the vernacular name used over most of its known range.

    Chikungunya virus (CHIKV), an alphavirus of the family Togaviridae, causes fever, polyarthritis and rash. There are three genotypes: West African, Asian and East/Central/South African (ECSA). The latter two genotypes have caused global outbreaks in recent years. Recent ECSA CHIKV outbreaks have been associated with severe neurological disease, but it is not known if different CHIKV genotypes are associated with different neurovirulence. In this study, the neurovirulence of Asian (MY/06/37348) and ECSA (MY/08/065) strains of CHIKV isolated in Malaysia were compared. Intracerebral inoculation of either virus into suckling mice was followed by virus titration, histopathology and gene expression analysis of the harvested brains. Both strains of CHIKV replicated similarly, yet mice infected with MY/06/37348 showed higher mortality. Histopathology findings showed that both CHIKV strains spread within the brain (where CHIKV antigen was localized to astrocytes and neurons) and beyond to skeletal muscle. In MY/06/37348-infected mice, apoptosis, which is associated with neurovirulence in alphaviruses, was observed earlier in brains. Comparison of gene expression showed that a pro-apoptotic gene (eIF2αK2) was upregulated at higher levels in MY/06/37348-infected mice, while genes involved in anti-apoptosis (BIRC3), antiviral responses and central nervous system protection (including CD40, IL-10RA, MyD88 and PYCARD) were upregulated more highly in MY/08/065-infected mice. In conclusion, the higher mortality observed following MY/06/37348 infection in mice is due not to higher viral replication in the brain, but to differentially expressed genes involved in host immune responses. These findings may help to identify therapeutic strategies and biomarkers for neurological CHIKV infections.

    The present study evaluated the incidence of breast cancer in Libya and described the clinicopathological and demographic features. These features were then compared with corresponding data from patients from sub-Saharan Africa (Nigeria) and Europe (Finland). The study consisted of 234 patients with breast carcinoma, admitted to the African Oncology Institute in Sabratha, Libya, during the years 2002-2006. The pathological features were collected from pathology reports, patient histories from hospital files and the Sabratha Cancer Registry. The demographic differences between the Libyan, Nigerian and Finnish populations were prominent. The mean age of breast cancer patients in Libya was 46 years which was almost identical to that of Nigeria, but much lower than that of Finland. The Libyan breast cancer incidence was evaluated as 18.8 per 100,000 female individuals. This incidence was markedly higher in Finland, but was also high in Nigeria. Libyan and Nigerian breast cancer is predominantly of premenopausal type and exhibits unfavorable characteristics such as high histological grade and stage, large tumor size and frequent lymph node metastases. However, the histological types and histopathological risk features show similar importance regarding survival as European breast cancer cases. Survival in Libya ranks between the rates of survival in Nigeria (lowest) and Finland (highest). In conclusion, in Libya and other African countries, premenopausal breast cancer is more common than postmenopausal breast cancer. However, the opposite is true for Europe. Population differences may be involved, as suggested by the known variation, in the distribution of genetic markers in these populations. Different types of environmental impacts, however, cannot be excluded.

    The tropical rain forests of Central Africa contain high levels of species diversity. Paleovegetation or biodiversity patterns suggested successive contraction/expansion phases on this rain forest cover during the last glacial maximum (LGM). Consequently, the hypothesis of the existence of refugia e.g. habitat stability that harbored populations during adverse climatic periods has been proposed. Understory species are tightly associated to forest cover and consequently are ideal markers of forest dynamics. Here, we used two central African rain forest understory species of the palm genus, Podococcus, to assess the role of past climate variation on their distribution and genetic diversity. Species distribution modeling in the present and at the LGM was used to estimate areas of climatic stability. Genetic diversity and phylogeography were estimated by sequencing near complete plastomes for over 120 individuals. Areas of climatic stability were mainly located in mountainous areas like the Monts de Cristal and Monts Doudou in Gabon, but also lowland coastal forests in southeast Cameroon and northeast Gabon. Genetic diversity analyses shows a clear North-South structure of genetic diversity within one species. This divide was estimated to have originated some 500,000years ago. We show that, in Central Africa, high and unique genetic diversity is strongly correlated with inferred areas of climatic stability since the LGM. Our results further highlight the importance of coastal lowland rain forests in Central Africa as harboring not only high species diversity but also important high levels of unique genetic diversity. In the context of strong human pressure on coastal land use and destruction, such unique diversity hotspots need to be considered in future conservation planning.

    Full Text Available European countries embarked on a European integration programme that saw the formation of the Euro, which has emerged as a major currency (Blair, 1999 that was introduced in 1998. With the Euro, came the establishment of the European Central Bank. Thus this study seeks to investigate the flaws in the formation of the European Central Bank that surfaced during the major economic crisis in Europe. The crisis revealing the gaps in the formation and structure of the European central bank have created major challenges for the Economic and Monetary Union (EMU. Through an extant review of literature the study will examine the East African Community Countries, investigating the ties they have to the euro zone to analyse how the crisis has affected them. Furthermore, the study will analyse what would happen to the growth patterns of the East African Countries and the various prospects they may have should the Eurozone come to an end.

    Positive psychological well-being is an important predictor of and contributor to medical student success. Previous work showed that first-year African American medical students whose self-concept was highly linked to their race (high racial identity centrality) were at greater risk for poor well-being. The current study extends this work by examining (a) whether the psychological impact of racial discrimination on well-being depends on African American medical students' racial identity centrality and (b) whether this process is explained by how accepted students feel in medical school. This study used baseline data from the Medical Student Cognitive Habits and Growth Evaluation (CHANGE) Study, a large national longitudinal cohort study of 4732 medical students at 49 medical schools in the USA (n = 243). Regression analyses were conducted to test whether medical student acceptance mediated an interactive effect of discrimination and racial identity centrality on self-esteem and well-being. Both racial identity centrality and everyday discrimination were associated with negative outcomes for first-year African American medical students. Among participants who experienced higher, but not lower, levels of everyday discrimination, racial identity centrality was associated with negative outcomes. When everyday discrimination was high, but not low, racial identity was negatively related to perceived acceptance in medical school, and this in turn was related to increased negative outcomes. Our results suggest that discrimination may be particularly harmful for African American students who perceive their race to be central to their personal identity. Additionally, our findings speak to the need for institutional change that includes commitment and action towards inclusivity and the elimination of structural racism.

    Full Text Available New detailed vegetation reconstructions are proposed in Atlantic Central Africa from a modern pollen data set derived from 199 sites (Cameroon, Gabon and Congo including 131 new sites. In this study, the concept of plant functional classification is improved with new and more detailed plant functional types (PFTs and new aggregations of pollen taxa. Using the biomisation method, we reconstructed (1 modern potential biomes and (2 potential succession stages of forest regeneration, a new approach in Atlantic Central African vegetation dynamics and ecosystem functioning reconstruction. When compared to local vegetation, potential biomes are correctly reconstructed (97.5% of the sites and tropical evergreen to semi-evergreen forest (TRFO biome is well identified from semi-deciduous forest (TSFO biome. When the potential biomes are superimposed on the White's vegetation map, only 76.4% of the sites are correctly reconstructed. But using botanical data, correspondence and cluster analyses, the 43 sites from Congo (Mayombe evidence more affinities with those of central Gabon and so they can also be considered as correctly reconstructed as TRFO biome and White's map must be revised. In terms of potential succession stages of forest regeneration, the mature forest (TMFO is well differentiated from the secondary forest (TSFE, but inside this latter group, the young and the pioneer stages are not clearly identified due probably to their low sampling representation. Moreover, linked to their progressive and mosaic character, the boundaries between two forest biomes or two forest stages are not clearly detected and need also a more intensive sampling in such transitions.

    Full Text Available Background: Elder abuse and neglect (EAN comprises emotional, financial, physical, and sexual abuse, neglect by other individuals, and self-neglect. Elder abuse and neglect in seniors with psychiatric morbidity was not monitored in the Czech Republic at all, despite the literature shows mental morbidity as one of the important risk factor for developing elder abuse and neglect.Methods: We designed comparative cross sectional study comprising 305 seniors hospitalized in Mental Hospital Kromeriz in June 2011 - group of 202 seniors hospitalized due to mental disorder in psychogeriatric ward and group of 103 seniors hospitalized due to somatic disorder in internal ward. Content analysis of medical records was done in both groups of seniors, with regards to symptoms of elder abuse. Then, we discussed the topic of elder abuse with 30 nurses of psychogeriatric ward in focus group interview.Results: Between two compared groups of seniors we detected statistically higher prevalence of elder abuse in seniors with psychiatric morbidity (48 cases, 23.8% prevalence of EAN, compared to somatically ill seniors (3 cases, 2.9%. As for nursing staff, 5 from 30 nurses (16.7% have never heard about symptoms of elder abuse and neglect, 10 from 30 nurses (33.3% had just a partial knowledge about elder abuse and neglect and its symptoms, the rest of nurses (15 from 30 nurses, 50.0% had good knowledge about elder abuse and neglect and its symptoms.Conclusion: Elder abuse and neglect seems to be a relevant problem in senior population with mental disorders. Development of educational programs for nursing and medical staff about Elder abuse and neglect (symptoms of EAN, early detection of EAN, knowledge how to report cases of EAN could improve the situation and help mentally ill seniors to better quality of life.

    At least 270 million people (58% of the total population) are at risk of cystic echinococcosis (CE) in Central Asia including areas of Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Afghanistan, Iran, Pakistan and western China. The annual surgical incidence rate in Uzbekistan and Tadjikistan has been estimated to be as high as 25-27 cases/100,000 with the highest prevalence reaching 10% (range from 0.8 to 11.9%) in some Tibetan communities in western China. Echinococcus transmission in the region is largely associated with social factors including limited community knowledge of echinococcosis, small-scale household animal production, home killing of livestock, and the feeding of dogs with uncooked offal. Alveolar echinococcosis (AE) is also endemic in Central Asia and is recognized as a major problem in some Tibetan communities with up to 6% of villagers infected in some villages. In western China, 5-30% of the population are seropositive against E. granulosus antigens, indicating that a large number of individuals have been exposed to the parasite. Although echinococcosis control programs have been initiated in some countries in Central Asia, control efforts are generally fragmented and uncoordinated. Monthly deworming of dogs with praziquantel (PZQ), as a key measure to control the Echinococcus parasites, has been used in western China. However, the approach has proven difficult in local semi-nomadic communities. Additional control measures including health education, domestic livestock animal treatment/vaccination and dog vaccination are needed in CE-endemic areas to accelerate progress.

    It is still unclear whether the exponential rise of atmospheric CO2 concentration has produced a fertilization effect on tropical forests, thus incrementing their growth rate, in the last two centuries. As many factors affect tree growth patterns, short -term studies might be influenced by the confounding effect of several interacting environmental variables on plant growth. Long-term analyses of tree growth can elucidate long-term trends of plant growth response to dominant drivers. The study of annual rings, applied to long tree-ring chronologies in tropical forest trees enables such analysis. Long-term tree-ring chronologies of three widespread African species were measured in Central Africa to analyze the growth of trees over the last two centuries. Growth trends were correlated to changes in global atmospheric CO2 concentration and local variations in the main climatic drivers, temperature and rainfall. Our results provided no evidence for a fertilization effect of CO2 on tree growth. On the contrary, an overall growth decline was observed for all three species in the last century, which appears to be significantly correlated to the increase in local temperature. These findings provide additional support to the global observations of a slowing down of C sequestration in the trunks of forest trees in recent decades. Data indicate that the CO2 increase alone has not been sufficient to obtain a tree growth increase in tropical trees. The effect of other changing environmental factors, like temperature, may have overridden the fertilization effect of CO2.

  19. Commodity fetichismo, the Holy Spirit, and the turn to Pentecostal and African Independent Churches in Central Mozambique.

    Pfeiffer, James

    2005-09-01

    Pentecostal and African Independent Churches have rapidly spread throughout central Mozambique in the aftermath of war and in the midst of a recent structural adjustment program that has hastened commoditization of community life and intensified local inequalities. This extraordinary expansion signals a shift away from reliance on "traditional" healers to treat persistent afflictions believed to have spiritual causes. Survey data and illness narratives collected from recent church recruits and local residents during research in 2002 and 2003 in the city of Chimoio reveal that healers have increased fees and tailored treatments to clients searching for good fortune in ways that have alienated many other help seekers in this changing social environment. While traditional healing has been celebrated in the international health world, community attitudes are less generous; many healers are increasingly viewed with suspicion because of their engagement with malevolent occult forces to foment social conflict, competition, and confrontation for high fees. Church healing approaches offer free and less divisive spiritual protection reinforced by social support in a new collectivity. One vital source of church popularity derives from pastors' efforts to tap the already considerable community anxiety over rising healer fees and their socially divisive treatments in an insecure environment.

  20. The Blaník Gneiss in the southern Bohemian Massif (Czech Republic): a rare rock composition among the early palaeozoic granites of Variscan Central Europe

    2016-08-01

    Metamorphosed and deformed tourmaline-bearing leucogranites with a Cambro-Ordovician formation age are widespread in the Monotonous Group of the Variscan southern Bohemian Massif, Czech Republic. The rocks, known locally as Blaník gneiss, are strongly peraluminous and classify as phosphorus-rich low-T, S-type granite. The magma formed from a metapelitic source, most likely through muscovite dehydration melting. With respect to its low-T origin and the abundance of tourmaline, the Blaník gneiss is exotic within the spectrum of Early Palaeozoic granites of the Variscan fold belt of Central Europe. Coeval granitic gneisses in the neighbouring Gföhl unit of the Bohemian Massif can be classified as higher T S-type granites and were probably generated through biotite dehydration melting. The geochemical differences between the Early Palaeozoic granitic magmatism in the Gföhl unit and the Monotonous Group support models claiming that these two geological units belonged to independent peri-Gondwana terranes before the Variscan collision. It is suggested here, that the Gföhl unit and the Monotonous Group represent zones of higher and lower heat flow within the Early Palaeozoic northern Gondwana margin, respectively. The geochemical data presented in this study could be helpful for terrane correlations and palaeogeographic reconstructions.

    Full Text Available Five provinces in central People’s Republic of China (P.R. China have successfully reduced the burden of malaria due to Plasmodium vivax in the last 7 years. The results of the Action Plan of China Malaria Elimination (APCME that com- menced in 2010 are analysed against the background of the progress reached by the national malaria control programme (NMEP that was launched in 2006. We examined the epidemiological changes in the number of autochthonous cases over time and discuss the feasibility of achieving the goal of malaria elimination by 2020. There was a total decline of 34,320 malaria cases between 2006 and 2012 arriving at an average annual incidence of 0.04 per 10,000 people by 2012. At the same time, the number of counties reporting autochthonous cases declined from 290 to 19. Spatial autocorrelation and Bayesian modelling were used to evaluate the datasets and predict the spatio-temporal pattern in the near future. The former approach showed that spatial clusters of P. vivax malaria existed in the study region during the study period, while the risk prediction map generated by the Bayesian model indicates that only sporadic malaria cases will appear during in the future. The results suggest that the initial NMEP approach and the follow-up APCME strategy have played a key role in reducing the threat of malaria in central P.R. China. However, to achieve the goal of malaria elimination by the end of the current decade, interven- tion plans must be adjusted with attention paid to those endemic counties still at risk according to the prediction map.

    The Doba gabbro was collected from an exploration well through the Cretaceous Doba Basin of Southern Chad. The gabbro is comprised mostly of plagioclase, clinopyroxene and Fe-Ti oxide minerals and displays cumulus mineral textures. Whole rock 40Ar/39Ar step-heating geochronology yielded a Late Permian plateau age of 257 ± 1 Ma. The major and trace elemental geochemistry shows that the gabbro is mildly alkalic to tholeiitic in composition and has trace element ratios (i.e. La/YbN > 7; Sm/YbPM > 3.4; Nb/Y > 1; Zr/Y > 5) indicative of a basaltic melt derived from a garnet-bearing sublithospheric mantle source. The moderately enriched Sr-Nd isotopes (i.e. ISr = 0.70495 to 0.70839; eNd(T) = -1.0 to -1.3) fall within the mantle array (i.e. OIB-like) and are similar to other Late Permian plutonic rocks of North-Central Africa (i.e. ISr = 0.7040 to 0.7070). The Late Permian plutonic igneous complexes of North-Central Africa are geologically associated with tectonic lineaments suggesting they acted as conduits for sublithospheric melts to migrate to middle/upper crustal levels. The source of the magmas may be related to the spatial-temporal association of North-Central Africa with the African large low shear velocity province (LLSVP). The African LLSVP has remained stable since the Late Carboniferous and was beneath the Doba basin during the Permian. We suggest that melts derived from deep seated sources related to the African LLSVP percolated through the North-Central African crust via older tectonic lineaments and form a discontiguous magmatic province.

    Many studies have examined the long-term effects of selective logging on the abundance and diversity of free-ranging primates. Logging is known to reduce the abundance of some primate species through associated hunting and the loss of food trees for frugivores; however, the potential role of pathogens in such primate population declines is largely unexplored. Selective logging results in a suite of alterations in host ecology and forest structure that may alter pathogen dynamics in resident wildlife populations. In addition, environmental pollution with human fecal material may present a risk for wildlife infections with zoonotic protozoa, such as Cryptosporidium and Giardia. To better understand this interplay, we compared patterns of infection with these potentially pathogenic protozoa in sympatric western lowland gorillas (Gorilla gorilla gorilla) and chimpanzees (Pan troglodytes troglodytes) in the undisturbed Goualougo Triangle of Nouabalé-Ndoki National Park and the adjacent previously logged Kabo Concession in northern Republic of Congo. No Cryptosporidium infections were detected in any of the apes examined and prevalence of infection with Giardia was low (3.73% overall) and did not differ between logged and undisturbed forest for chimpanzees or gorillas. These results provide a baseline for prevalence of these protozoa in forest-dwelling African apes and suggest that low-intensity logging may not result in long-term elevated prevalence of potentially pathogenic protozoa.

    SRS are no longer in use, they are declared as disused, and they are transferred to the central radioactive management facility (CRMF) belonging to Tanzania Atomic Energy Commission (regulatory body) and managed as radioactive waste. In order to reduce the risk associated with disused sealed radioactive sources (DSRS), the first priority would be to bring them to appropriate controls under the regulatory body. When DSRS are safely managed, regulatory body need to make assessment of the likelihood and potential impact of incidents, accidents and hazards for proper management plan. The paper applies Analytical Hierarchy Process (AHP) for assessing and allocating weights and priorities for solving the problem of mult criteria consideration for management plan. Using pairwise comparisons, the relative importance of one criterion over another can be expressed. The method allows decision makers to provide judgments about the relative importance of each criterion and to estimate radiological risk by using expert's judgments or probability of occurrence. AHP is the step by step manner where the resulting priorities are shown and the possible inconsistencies are determined. The Information provided by experts helps to rank hazards according to probability of occurrence, potential impact and mitigation cost. The strength of the AHP method lies in its ability to incorporate both qualitative and quantitative data in decision making. AHP present a powerful tool for weighting and prioritizing hazards in terms of occurrence probability. However, AHP also has some weak points. AHP requires data based on experience, knowledge and judgment which are subjective for each decision-maker.

  8. Long tree-ring chronologies provide evidence of recent tree growth decrease in a Central African tropical forest.

    Directory of Open Access Journals (Sweden)

    Giovanna Battipaglia

    Full Text Available It is still unclear whether the exponential rise of atmospheric CO2 concentration has produced a fertilization effect on tropical forests, thus incrementing their growth rate, in the last two centuries. As many factors affect tree growth patterns, short -term studies might be influenced by the confounding effect of several interacting environmental variables on plant growth. Long-term analyses of tree growth can elucidate long-term trends of plant growth response to dominant drivers. The study of annual rings, applied to long tree-ring chronologies in tropical forest trees enables such analysis. Long-term tree-ring chronologies of three widespread African species were measured in Central Africa to analyze the growth of trees over the last two centuries. Growth trends were correlated to changes in global atmospheric CO2 concentration and local variations in the main climatic drivers, temperature and rainfall. Our results provided no evidence for a fertilization effect of CO2 on tree growth. On the contrary, an overall growth decline was observed for all three species in the last century, which appears to be significantly correlated to the increase in local temperature. These findings provide additional support to the global observations of a slowing down of C sequestration in the trunks of forest trees in recent decades. Data indicate that the CO2 increase alone has not been sufficient to obtain a tree growth increase in tropical trees. The effect of other changing environmental factors, like temperature, may have overridden the fertilization effect of CO2.

    Background: Chikungunya virus (CHIKV) is an arbovirus that causes an acute febrile syndrome with a severe and debilitating arthralgia. In Brazil, the Asian and East-Central South African (ECSA) genotypes are circulating in the north and northeast of the country, respectively. In 2015, the first autochthonous cases in Rio de Janeiro, Brazil were reported but until now the circulating strains have not been characterized. Therefore, we aimed here to perform the molecular characterization and phylogenetic analysis of CHIKV strains circulating in the 2016 outbreak occurred in the municipality of Rio de Janeiro. Methods: The cases analyzed in this study were collected at a private Hospital, from April 2016 to May 2016, during the chikungunya outbreak in Rio de Janeiro, Brazil. All cases were submitted to the Real Time RT-PCR for CHIKV genome detection and to anti-CHIKV IgM ELISA. Chikungunya infection was laboratorially confirmed by at least one diagnostic method and, randomly selected positive cases (n=10), were partially sequenced (CHIKV E1 gene) and analyzed. Results: The results showed that all the samples grouped in ECSA genotype branch and the molecular characterization of the fragment did not reveal the A226V mutation in the Rio de Janeiro strains analyzed, but a K211T amino acid substitution was observed for the first time in all samples and a V156A substitution in two of ten samples. Conclusions: Phylogenetic analysis and molecular characterization reveals the circulation of the ECSA genotype of CHIKV in the city of Rio de Janeiro, Brazil and two amino acids substitutions (K211T and V156A) exclusive to the CHIKV strains obtained during the 2016 epidemic, were reported.

    Several studies of environmental samples indicate that the levels of many persistent organic pollutants (POPs) are increasing in Africa, but few studies have been conducted in humans. Simultaneously, many African countries are experiencing a rapid economic growth and implementing information and communication technologies (ICT). These changes have generated high amounts of electronic waste (e-waste) that have not been adequately managed. We tested the hypothesis that the current levels of two main classes of POPs in Western and Central African countries are affected by the degree of socioeconomic development. We measured the levels of 36 POPs in the serum of recent immigrants (N = 575) who came from 19 Sub-Saharan countries to the Canary Islands (Spain). We performed statistical analyses on their anthropometric and socioeconomic data. High median levels of POPs were found in the overall sample, with differences among the countries. Organochlorine pesticide (OCP) and polychlorinated biphenyl (PCB) levels increased with age. People from low-income countries had significantly higher OCP levels and much lower PCB levels than those from high-income countries. We found a significant association between the implementation of ICT and PCB contamination. Immigrants from the countries with a high volume of imports of second-hand electronic equipment had higher PCB levels. The economic development of Africa and the e-waste generation have directly affected the levels of POPs. The POP legacies of these African populations most likely are due to the inappropriate management of the POPs' residues. - Highlights: • Higher levels of organochlorine pesticides in Africans from low-income countries • Higher levels of PCBs in Africans from high-income countries • Levels of PCBs are significantly higher in people from West Africa. • Significant association between implementation of ICT and PCB contamination • High volume of second-hand electronic equipment is associated

    Background Chikungunya virus (CHIKV) is a re-emerging mosquito-borne virus which causes epidemics of fever, severe joint pain and rash. Between 2005 and 2010, the East/Central/South African (ECSA) genotype was responsible for global explosive outbreaks across India, the Indian Ocean and Southeast Asia. From late 2013, Asian genotype CHIKV has caused outbreaks in the Americas. The characteristics of cross-antibody efficacy and epitopes are poorly understood. Methodology/Principal Findings We characterized human immune sera collected during two independent outbreaks in Malaysia of the Asian genotype in 2006 and the ECSA genotype in 2008–2010. Neutralizing capacity was analyzed against representative clinical isolates as well as viruses rescued from infectious clones of ECSA and Asian CHIKV. Using whole virus antigen and recombinant E1 and E2 envelope glycoproteins, we further investigated antibody binding sites, epitopes, and antibody titers. Both ECSA and Asian sera demonstrated stronger neutralizing capacity against the ECSA genotype, which corresponded to strong epitope-antibody interaction. ECSA serum targeted conformational epitope sites in the E1-E2 glycoprotein, and E1-E211K, E2-I2T, E2-H5N, E2-G118S and E2-S194G are key amino acids that enhance cross-neutralizing efficacy. As for Asian serum, the antibodies targeting E2 glycoprotein correlated with neutralizing efficacy, and I2T, H5N, G118S and S194G altered and improved the neutralization profile. Rabbit polyclonal antibody against the N-terminal linear neutralizing epitope from the ECSA sequence has reduced binding capacity and neutralization efficacy against Asian CHIKV. These findings imply that the choice of vaccine strain may impact cross-protection against different genotypes. Conclusion/Significance Immune serum from humans infected with CHIKV of either ECSA or Asian genotypes showed differences in binding and neutralization characteristics. These findings have implications for the continued

    The Southern African Development Coordination Conference (SADCC) which unites 9 states with a combined population of 60 million, has as its objective the task of promoting economic development and realizing economic independence. In many respects the strain of neocolonialism that Southern Africa faces at this time is even more virulent than that facing West, Central, and East Africa. In the latter regions the surrender of political authority by colonial administrators frequently left the commercial, agricultural, and industrial interests of the European powers in continued control of the economies of the former colonies. The fate of economic development plans was determined by situations and decisions made in places distant from the African continent. In the case of Southern Africa, the withdrawal or expulsion of European colonialists has found whites in neighboring South Africa most eager to step into the economic breech. For most of the Southern African states this variant strain of the neocolonial virus creates a dual problem: the independent states acting separately have been no match for South Africa; and the acquiescence of independent African states in forging economic links with South Africa has impeded the liberation efforts of Africans in Namibia and the Republic of South Africa. Discussion focus turns to the challenges that confront SADCC; transport as the most significant factor accounting for the dependency of SADCC states upon South Africa; the role of minerals in dependency; other aspects of dependency; South Africa's proposed Constellation of States; the origins and objectives of SADCC; and dollars and donors. SADCC planning for economic liberation has been conducted against the background of a counterproposal advanced by South Africa's government, which put the Republic at the center of an expanded network of economic linkages within the entire southern African region. While being formally rejected, the Constellation of States scheme does have

    BACKGROUND: The full-length (L-) variant of caspase-12 is believed to predispose to sepsis. It has been replaced in the genome of most human populations by the (S-) variant, which leads to premature termination of translation. Strikingly, the L-allele is still widely prevalent in African populations

    Full Text Available A new pollen sequence from the Lake Mbalang (7°19´ N, 13°44´ E, 1110 m a.s.l. located on the eastern Adamawa plateau, in Central Cameroon, is presented in this paper to analyze the Holocene African Humid Period (AHP termination and related vegetation changes at 7° N in tropical Africa, completing an important transect for exploring shifts in the northern margin of the African Monsoon. This sequence, spanning the last 7000 cal yr BP, shows that the vegetation response to this transitional climatic period was marked by significant successional changes within the broad context of long-term aridification. Semi-deciduous/sub-montane forest retreat in this area is initially registered as early as ca. 6100 cal yr BP and modern savannah was definitely established at ca. 3000 cal yr BP and stabilized at ca. 2400 cal yr BP; but a slight forest regeneration episode is observed between ca. 5200 and ca. 4200 cal yr BP. In this area with modern high rainfall, increasing in the length of the dry season during the AHP termination linked to a contraction of the northern margin of the Intertropical Convergence Zone (ITCZ from ca. 6100 cal yr BP onward, probably associated with decreasing in cloud cover and/or fog frequency, has primarily controlled vegetation dynamics and above all the disappearance of the forested environment on the Adamawa plateau. Compared to previous studies undertaken in northern tropical and Central Africa, this work clearly shows that the response of vegetation to transitional periods between climatic extremes such as the AHP termination might be different in timing, mode and amplitude according to the regional climate of the study sites, but also according to the stability of vegetation before and during these climatic transitions.

    The Matala Dome (MD), an ENE-trending structure located at the junction between the Pan-African Lufilian and Zambezi belts, is cored by a Gneiss-Schist Unit with uncertain age overlain by a metasedimentary section (Quartzite-Schist Unit, Marble Unit and Carbonate-Siliciclastic Unit) of the Neoproterozoic to Cambrian Katanga Supergroup. The top of the Katangan stratigraphy is represented by synorogenic sedimentary rocks—Upper Siliciclastic Unit. An early event D1 resulted in the development of shallow-dipping metamorphic foliation S1 and pre- to syntectonic growth of garnet and kyanite in the schists of the Quartzite-Schist Unit. Pseudosections and garnet isopleth modelling on schist from this unit defined the peak metamorphism at P = 7.5-9.3 kbar and T = 620-700 °C. U-Pb detrital zircon dating revealed ca. 2.7 Ga source and a high-grade metamorphism during Pan-African times. The S1 foliation was affected by upright folding F2 with ENE-trending axes and associated subvertical crenulation fabric S2 development. The syn-D2 retrogression in the schists is marked by post-S1 staurolite crystallisation and further by chloritisation followed by sericitisation. The D2 event is interpreted to have exhumed the orogenic middle crust and to be responsible for the domal structure of the MD. 40Ar/39Ar dating of muscovite at 529.3 ± 5.6 to 526.3 ± 6.2 is interpreted to date the exhumation event. D2 is correlated with regional N-S shortening event at ca. 530-520 Ma. Based on the lithology, structural record, and time and facies of the metamorphism, a correlation between the MD and the northern part of the Zambezi Belt is suggested.

    Full Text Available Identification of fossil cichlids is difficult, because the currently used diagnostic morphological characters for living cichlids are mostly soft tissue based and such characters are hardly preserved in fossils. During our recent fieldwork in the Central Kenya Rift (E-Africa, we discovered several exceptionally well-preserved fossil cichlids, which can be assigned to different lineages among the African Pseudocrenilabrinae. Here we present one of those new specimens. Its most conspicuous character is a lateral line divided into three segments. This specimen was found in the lacustrine sediments of the Middle Miocene site Waril, Tugen Hills, Kenya. The site represents the deposits of an ancient freshwater lake ca. 9-10 million years ago. Previous work on fossil leaves from the same site allow for the reconstruction of open vegetation surrounding the lake and pronounced dry seasons. Among the main further characteristics of the new fossil cichlid is a lachrimal with six lateral line canals, big cycloid scales and a low number of dorsal fin spines (XIII. The latter two characters are traceable in several members of tribes within the Pseudocrenilabrinae. However, a lachrimal with six lateral line canals is exclusively found in certain tribes of the EAR (East African Radiation within the Pseudocrenilabrinae. Moreover, the unique lateral line pattern is solely present in two genera of the EAR tribe Ectodini. However, the fossil shows cycloid scales, while modern Ectodini have ctenoid scales. Taken all evidence together, this fossil may perhaps represent an ancient lineage related to the Ectodini. Up to date, there is no definite fossil record of the members of the EAR. Our fossil may represent the first reliable calibration point for this group, which would be consistent with the previously reconstructed diversification time of the H-lineage (EAR tribes, except Boulengerochromini, Bathybatini, Trematocarini and Lamprologini and the Lamprologini ca

  3. Wood Specific Gravity Variations and Biomass of Central African Tree Species: The Simple Choice of the Outer Wood.

    Jean-François Bastin

    Full Text Available Wood specific gravity is a key element in tropical forest ecology. It integrates many aspects of tree mechanical properties and functioning and is an important predictor of tree biomass. Wood specific gravity varies widely among and within species and also within individual trees. Notably, contrasted patterns of radial variation of wood specific gravity have been demonstrated and related to regeneration guilds (light demanding vs. shade-bearing. However, although being repeatedly invoked as a potential source of error when estimating the biomass of trees, both intraspecific and radial variations remain little studied. In this study we characterized detailed pith-to-bark wood specific gravity profiles among contrasted species prominently contributing to the biomass of the forest, i.e., the dominant species, and we quantified the consequences of such variations on the biomass.Radial profiles of wood density at 8% moisture content were compiled for 14 dominant species in the Democratic Republic of Congo, adapting a unique 3D X-ray scanning technique at very high spatial resolution on core samples. Mean wood density estimates were validated by water displacement measurements. Wood density profiles were converted to wood specific gravity and linear mixed models were used to decompose the radial variance. Potential errors in biomass estimation were assessed by comparing the biomass estimated from the wood specific gravity measured from pith-to-bark profiles, from global repositories, and from partial information (outer wood or inner wood.Wood specific gravity profiles from pith-to-bark presented positive, neutral and negative trends. Positive trends mainly characterized light-demanding species, increasing up to 1.8 g.cm-3 per meter for Piptadeniastrum africanum, and negative trends characterized shade-bearing species, decreasing up to 1 g.cm-3 per meter for Strombosia pustulata. The linear mixed model showed the greater part of wood specific gravity

    Full Text Available Abstract Background Photoperiod-sensitive flowering is a key adaptive trait for sorghum (Sorghum bicolor in West and Central Africa. In this study we performed an association analysis to investigate the effect of polymorphisms within the genes putatively related to variation in flowering time on photoperiod-sensitive flowering in sorghum. For this purpose a genetically characterized panel of 219 sorghum accessions from West and Central Africa was evaluated for their photoperiod response index (PRI based on two sowing dates under field conditions. Results Sorghum accessions used in our study were genotyped for single nucleotide polymorphisms (SNPs in six genes putatively involved in the photoperiodic control of flowering time. Applying a mixed model approach and previously-determined population structure parameters to these candidate genes, we found significant associations between several SNPs with PRI for the genes CRYPTOCHROME 1 (CRY1-b1 and GIGANTEA (GI. Conclusions The negative values of Tajima's D, found for the genes of our study, suggested that purifying selection has acted on genes involved in photoperiodic control of flowering time in sorghum. The SNP markers of our study that showed significant associations with PRI can be used to create functional markers to serve as important tools for marker-assisted selection of photoperiod-sensitive cultivars in sorghum.

    Full Text Available The primary objective of this paper is to analyse households’ adaptation measures to the impacts of repeated extreme weather events, specifically floods, which belong amongst the most serious manifestation of ongoing climate change in Europe. The case study focuses on a rural area in the north-east part of the Czech Republic, in the catchment basin of the Bečva River. A total of 605 households were addressed within the framework of the questionnaire survey. On the basis of the conducted research, we determined that the total amount of adaptation measures adopted by those dwelling in residential homes within the investigated catchment area was relatively low. In contrast, however, one of the most important adaptation measures—house elevation—was applied by 46.94% of the houses (up to 1 m and by 21.16% houses (elevated more than 1 m respectively. We also found that the amount and scope of adaptation measures realized by households were influenced by certain socio-demographic factors of the inhabitants. The most statistically significant factors included households with more residents or families with more children living in the household, as well as those with a higher level of education. Flood experience, the level of damage, and individual flood risk perception also played an important role.

  6. The taxonomic status of two West African Leptopelis species: L. macrotis Schiøtz, 1967 and L. spiritusnoctis Rödel, 2007 (Amphibia: Anura: Arthroleptidae

    Full Text Available We herein examine the taxonomic status of two West African forest-dwelling Leptopelis species. The small L. spiritusnoctis, described from the Upper Guinean forests of West Africa, was recently synonymized with L. aubryi, described from Gabon. The large L. macrotis, known from Ghana to Sierra Leone, was downgraded to a subspecies of L. millsoni, ranging from the Niger Delta to eastern Democratic Republic of Congo. These taxonomic decisions are in contrast to the general biogeographic pattern of African forest anurans and we consequently tested if the morphologically similar taxon pairs are indeed conspecifics by applying acoustic and molecular techniques. Both techniques confirmed that populations from West Africa differ significantly from their Central African morphological equivalents. Consequently, we herein resurrect L. spiritusnoctis as a valid species. The acoustic data indicate that L. aubryi may comprise a complex of cryptic species. We further advocate using the name L. macrotis for West African and L. millsoni for Central African populations of these larger arboreal frogs. However, we had neither genetic nor acoustic data from the type locality of L. millsoni available and could not clarify if these frogs belong to the more western or eastern taxon or even represent a Nigerian endemic. Thus, it is possible that West African populations need to be termed L. millsoni in the future. For populations east of the Cross River, Nigeria, the name L. guineensis would be available.

    Objective:To understand the epidemiology of the East, Central and South African(ECSA) genotype of Chikungunya virus(CHIKV)in terms of emerging and re-emerging infections, this study has been aimed at investigating the evolutionary parameters, genomic signatures and molecular tracking of theCHIKV ECSA genotype in South-east Asia and coastal areas of the Indian Ocean between 2006 and 2009 by using phylogenetic analysis and the Bayesian Markov Chain Monte Carlo (BMCMC) evolutionary estimation.Methods: Nearly complete genome sequences of53 CHIKV isolates from all genotypes were subjected to phylogenetic analysis and evolutionary parameter estimation. The amino acids of67of ECSA genotype during2006 to2009 were compared for finding molecular signature tracking. The ECSA genotype signatures were visualized to find the possible transmission root was projected onto a geographic map.Results:Phylogenetic analysis showed theECSA genotype was divided into2 groups. The first group comprises viruses from India and Southeast Asian countries. The second group consists of strains typically circulating in Sri Lanka in2008. The evolutionary parameters of these groups depicted the time of the most recent common ancestor at approximately 7.5years ago. The genomic signatures revealed the positions of amino acid variation in each group.Conclusions:The molecular evolution projected onto a geographical map showed the routes ofCHIKVtransmission from 2006 to2009. Molecular tracking will assist in understanding transmission routes, epidemiology and molecular evolution ofCHIKV.

    Non-uniqueness of satellite gravity interpretation has traditionally been reduced by using a priori information from seismic tomography models. This reduction in the non-uniqueness has been based on velocity-density conversion formulas or user interpretation of the 3D subsurface structures (objects) based on the seismic tomography models and then forward modelling these objects. However, this form of object-based approach has been done without a standardized methodology on how to extract the subsurface structures from the 3D models. In this research, a 3D object-oriented image analysis (3D OOA) approach was implemented to extract the 3D subsurface structures from geophysical data. The approach was applied on a 3D shear wave seismic tomography model of the central part of the East African Rift System. Subsequently, the extracted 3D objects from the tomography model were reconstructed in the 3D interactive modelling environment IGMAS+, and their density contrast values were calculated using an object-based inversion technique to calculate the forward signal of the objects and compare it with the measured satellite gravity. Thus, a new object-based approach was implemented to interpret and extract the 3D subsurface objects from 3D geophysical data. We also introduce a new approach to constrain the interpretation of the satellite gravity measurements that can be applied using any 3D geophysical model.

    African clawed frogs, genus Xenopus, are extraordinary among vertebrates in the diversity of their polyploid species and the high number of independent polyploidization events that occurred during their diversification. Here we update current understanding of the evolutionary history of this group and describe six new species from west and central sub-Saharan Africa, including four tetraploids and two dodecaploids. We provide information on molecular variation, morphology, karyotypes, vocalizations, and estimated geographic ranges, which support the distinctiveness of these new species. We resurrect Xenopus calcaratus from synonymy of Xenopus tropicalis and refer populations from Bioko Island and coastal Cameroon (near Mt. Cameroon) to this species. To facilitate comparisons to the new species, we also provide comments on the type specimens, morphology, and distributions of X. epitropicalis, X. tropicalis, and X. fraseri. This includes significantly restricted application of the names X. fraseri and X. epitropicalis, the first of which we argue is known definitively only from type specimens and possibly one other specimen. Inferring the evolutionary histories of these new species allows refinement of species groups within Xenopus and leads to our recognition of two subgenera (Xenopus and Silurana) and three species groups within the subgenus Xenopus (amieti, laevis, and muelleri species groups).

    Central Africa is known for its strong biogenic, pyrogenic, and to a lesser extent anthropogenic emissions. Satellite observations of species like nitrogen dioxide (NO2) and formaldehyde (HCHO), as well as inverse modelling results have shown that there are large uncertainties associated with the emissions in this region. There is thus a need for additional measurements, especially from the ground, in order to better characterise the biomass-burning and biogenic products emitted in this area. We present MAX-DOAS measurements of NO2, HCHO, and aerosols performed in Central Africa, in the city of Bujumbura, Burundi (3°S, 29°E, 850m). A MAX-DOAS instrument has been operating at this location by BIRA-IASB since late 2013. Aerosol-extinction and trace-gases vertical profiles are retrieved by applying the optimal-estimation-based profiling tool bePRO to the measured O4, NO2 and HCHO slant-column densities. The MAX-DOAS vertical columns and profiles are used for investigating the diurnal and seasonal cycles of NO2, HCHO, and aerosols. Regarding the aerosols, the retrieved AODs are compared to co-located AERONET sun photometer measurements for verification purpose, while in the case of NO2 and HCHO, the MAX-DOAS vertical columns and profiles are used for validating GOME-2 and OMI satellite observations. To characterise the biomass-burning and biogenic emissions in the Bujumbura region, the trace gases and aerosol MAX-DOAS retrievals are used in combination to MODIS fire counts/radiative-power and GOME-2/OMI NO2 and HCHO satellite data, as well as simulations from the NOAA backward trajectory model HYSPLIT. First results show that HCHO seasonal variation around local noon is driven by the alternation of rain and dry periods, the latter being associated with intense biomass-burning agricultural activities and forest fires in the south/south-east and transport from this region to Bujumbura. In contrast, NO2 is seen to depend mainly on local emissions close to the city, due

    The green leafy vegetables Cnidoscolus aconitifolius and Crotalaria longirostrata are native to Mexico and Central America, while Solanum scabrum and Gynandropsis gynandra are native to Africa. They are consumed in both rural and urban areas in those places as a main food, food ingredient or traditional medicine. Currently, there is limited information about their nutritional and phytochemical composition. Therefore, mineral, vitamin C, phenolic and flavonoid concentration, and antioxidant activity were evaluated in multiple accessions of these leafy vegetables, and their mineral and vitamin C contribution per serving was calculated. The concentrations of Ca, K, Mg and P in these leafy vegetables were 0.82-2.32, 1.61-7.29, 0.61-1.48 and 0.27-1.44 mg/g fresh weight (FW), respectively. The flavonoid concentration in S. scabrum accessions was up to 1413 μg catechin equivalents/g FW, while the highest antioxidant activities were obtained in C. longirostrata accessions (52-60 μmol Trolox equivalents/g FW). According to guidelines established by the US Food and Drug Administration, a serving size (30 g FW) of C. longirostrata would be considered an excellent source of Mo (20 % or more of the daily value), and a serving of any of these green leafy vegetables would be an excellent source of vitamin C. Considering the importance of the minerals, phytochemicals and antioxidants in human health and their presence in these indigenous green leafy vegetables, efforts to promote their consumption should be implemented.

    Full Text Available In central Africa, most of the timber species require high light at the seedling stage for survival and growth. Forest managers face a regeneration shortage of these light-demanding timber species. To achieve long-term sustainability, there is a need for enrichment methods combining low cost and high species performance. The aim of this study was to assess the performance of Pericopsis elata seedlings in enriched logging gaps in Cameroon. Over five years; the survival and size of each seedling was monitored in 27 logging gaps that were either left without maintenance or cleared. Gaps were relatively small with an average total area of 155 m2. We found that planted seedlings of P. elata performed well in logging gaps. Even without any maintenance 61% of the planted seedlings survived after five years with an average annual diameter increment of 0.28 cm. P. elata appeared to be a good candidate species for enrichment in logging gaps. We demonstrated that the seedlings of P. elata tolerated a wide range of soil conditions but that their performance was strongly influenced by light availability (gap clearance, suggesting potentially improved performance of P. elata in high light environments such as in plantation or larger gaps.

    West African Craton (end Early Cambrian) and during the polyphased Hercynian-Variscan Orogeny that extended the final closure of the Paleotethys Ocean and resulted in the formation of the Maghrebian and Mauritanides belts. Only gentle deformation affected central and northeastern African during the Paleozoic, the latter remaining a passive margin of the Paleotethys Ocean up to the Early Permian when the development of the Neotethys initiated along the Eastern Mediterranean Basins. The Mesozoic-Cenozoic sedimentary sequence similarly consists of a succession of eustatically and tectonically controlled depositional cycles. Through time, progressive southwards shift of the basin margins occurred, related to the opening of the Neotethys Ocean and to the transgressions resulting from warming of the global climate and associated rise of the global sea level. The Guinean-Nigerian Shield, the Hoggar, Tibesti-Central Cyrenaica, Nubia, western Saudi Arabia, Central African Republic, and other long-lived arches delimited the principal basins. The main tectonic events were the polyphased extension, inversion, and folding of the northern African-Arabian shelf margin resulting in the development of the Alpine Maghrebian and Syrian Arc belts, rifting and drifting along the Central Atlantic, Somali Basins, and Gulf of Aden-Red Sea domains, inversion of the Murzuq-Djado Basin, and rifting and partial inversion along the Central African Rift System. Two major compressional events occurred in the Late Santonian and early Late Eocene. The former entailed folding and strike-slip faulting along the northeastern African-northern Arabian margin (Syrian Arc) and the Central African Fold Belt System (from Benue to Ogaden), and thrusting in Oman. The latter ("Pyrenean-Atlasic") resulted in folding, thrusting, and local metamorphism of the northern African-Arabian plate margin, and rejuvenation of intra-plate fault zones. Minor or more localized compressional deformations took place in the end

  18. Diet-related buccal dental microwear patterns in Central African Pygmy foragers and Bantu-speaking farmer and pastoralist populations.

    Directory of Open Access Journals (Sweden)

    Alejandro Romero

    Full Text Available Pygmy hunter-gatherers from Central Africa have shared a network of socioeconomic interactions with non-Pygmy Bantu speakers since agropastoral lifestyle spread across sub-Saharan Africa. Ethnographic studies have reported that their diets differ in consumption of both animal proteins and starch grains. Hunted meat and gathered plant foods, especially underground storage organs (USOs, are dietary staples for pygmies. However, scarce information exists about forager-farmer interaction and the agricultural products used by pygmies. Since the effects of dietary preferences on teeth in modern and past pygmies remain unknown, we explored dietary history through quantitative analysis of buccal microwear on cheek teeth in well-documented Baka pygmies. We then determined if microwear patterns differ among other Pygmy groups (Aka, Mbuti, and Babongo and between Bantu-speaking farmer and pastoralist populations from past centuries. The buccal dental microwear patterns of Pygmy hunter-gatherers and non-Pygmy Bantu pastoralists show lower scratch densities, indicative of diets more intensively based on nonabrasive foodstuffs, compared with Bantu farmers, who consume larger amounts of grit from stoneground foods. The Baka pygmies showed microwear patterns similar to those of ancient Aka and Mbuti, suggesting that the mechanical properties of their preferred diets have not significantly changed through time. In contrast, Babongo pygmies showed scratch densities and lengths similar to those of the farmers, consistent with sociocultural contacts and genetic factors. Our findings support that buccal microwear patterns predict dietary habits independent of ecological conditions and reflect the abrasive properties of preferred or fallback foods such as USOs, which may have contributed to the dietary specializations of ancient human populations.

To identify key surfaces, the principles of sequence stratigraphy and electrosequence analysis were used together with the well logs and well cores data as well as data obtained from final reports. The identified sequence boundaries (SB and surfaces (ts, mfs divide the Sarmatian sediments into sequences of the relative base level change of the third and fourth order. Except the third order cycle related to Haq's TB 2.6 cycle, which includes the whole Sarmatian stage, two individual cycles of higher order were revealed in the sedimentary record for the Moravian Central Depression. Their occurrence was also proved in Austrian as well as in Slovak part of the Vienna Basin, what points to their interregional character.

    An epidemiological study of African swine fever (ASF) was conducted between March 2006 and September 2007 in a rural area adjacent to the Gorongosa National park (GNP) located in the Central Mozambique. Domestic pigs and warthogs were sampled to determine the prevalence of antibodies against ASF virus and the salivary antigens of Ornithodoros spp. ticks, while ticks collected from pig pens were tested for the presence of ASFV. In addition, 310 framers were interviewed to gain a better understanding of the pig value chain and potential practices that could impact on the spread of the virus. The sero-prevalence to ASFV was 12.6% on farms and 9.1% in pigs, while it reached 75% in warthogs. Approximately 33% of pigs and 78% of warthogs showed antibodies against salivary antigens of ticks. The differences in sero-prevalence between farms close to the GNP, where there is greater chance for the sylvatic cycle to cause outbreaks, and farms located in the rest of the district, where pig to pig transmission is more likely to occur, were marginally significant. Ornithodoros spp. ticks were found in only 2 of 20 pig pens outside the GNP, and both pens had ticks testing positive for ASFV DNA. Interviews carried out among farmers indicated that biosecurity measures were mostly absent. Herd sizes were small with pigs kept in a free-ranging husbandry system (65%). Only 1.6% of farmers slaughtered on their premises, but 51% acknowledged allowing visitors into their farms to purchase pigs. ASF outbreaks seemed to have a severe economic impact with nearly 36% of farmers ceasing pig farming for at least 1 year after a suspected ASF outbreak. This study provides the first evidence of the existence of a sylvatic cycle in Mozambique and confirms the presence of a permanent source of virus for the domestic pig value chain.

  2. Pronounced Seasonal Changes in the Movement Ecology of a Highly Gregarious Central-Place Forager, the African Straw-Coloured Fruit Bat (Eidolon helvum.

    Directory of Open Access Journals (Sweden)

    Jakob Fahr

    Full Text Available Straw-coloured fruit bats (Eidolon helvum migrate over vast distances across the African continent, probably following seasonal bursts of resource availability. This causes enormous fluctuations in population size, which in turn may influence the bats' impact on local ecosystems. We studied the movement ecology of this central-place forager with state-of-the-art GPS/acceleration loggers and concurrently monitored the seasonal fluctuation of the colony in Accra, Ghana. Habitat use on the landscape scale was assessed with remote sensing data as well as ground-truthing of foraging areas.During the wet season population low (~ 4000 individuals, bats foraged locally (3.5-36.7 km in urban areas with low tree cover. Major food sources during this period were fruits of introduced trees. Foraging distances almost tripled (24.1-87.9 km during the dry season population peak (~ 150,000 individuals, but this was not compensated for by reduced resting periods. Dry season foraging areas were random with regard to urban footprint and tree cover, and food consisted almost exclusively of nectar and pollen of native trees.Our study suggests that straw-coloured fruit bats disperse seeds in the range of hundreds of meters up to dozens of kilometres, and pollinate trees for up to 88 km. Straw-coloured fruit bats forage over much larger distances compared to most other Old World fruit bats, thus providing vital ecosystem services across extensive landscapes. We recommend increased efforts aimed at maintaining E. helvum populations throughout Africa since their keystone role in various ecosystems is likely to increase due to the escalating loss of other seed dispersers as well as continued urbanization and habitat fragmentation.

    Affinnih, Yahya H

    2002-02-01

    This article takes an international perspective on the drug problem in sub-Saharan Africa. This analysis borrows ideas from physical and economic geography as a heuristic device to conceptualize the global narcoscapes in which drug trafficking occurs. Both the legitimate and the illegal drug trade operate within the same global capitalist system and draw on the same technological innovations and business processes. Central to the paper's argument is evidence that sub-Saharan African countries are now integrated into the political economy of drug consumption due to the spill-over effect. These countries are now minor markets for "hard drugs" as the result of the activities of organizations and individual traffickers that use Africa as a staging point in their trade with Europe and the United States. As a result, sub-Saharan African countries have drug consumption problems that were essentially absent prior to 1980, along with associated health, social, and economic costs. The emerging drug problem has forced African countries to develop their own drug control policy. The sub-Saharan African countries mentioned below vary to some extent in the level of drug use and misuse problems: Burundi, Comoros, Djibouti, Eritrea, Ethiopia, Kenya, Madagascar, Malawi, Mauritius, Mozambique, Reunion, Rwanda, Seychelles, Somalia, Tanzania, Uganda, Zambia, Angola, Cameroon, Central African Republic, Chad, Congo, Congo (Zaire), Equatorial Guinea, Gabon, Sao Tome and Principe, Botswana, Lesotho, Namibia, South Africa, Swaziland, Benin, Burkina Faso, Cape Verde, Cote d'Ivoire, Gambia, Ghana, Guinea, Guinea Bissau, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, and Togo. As part of this effort, African countries are assessing the health, social, and economic costs of drug-use-related problems to pinpoint methods which are both effective and inexpensive, since their budgets for social programs are severely constrained. Many have progressed to the point of adopting anti

    The present External Quality Assessment (EQA) assessed microscopy of blood parasites among diagnostic laboratories in the Democratic Republic of the Congo. The EQA addressed 445 participants in 10/11 provinces (October 2013-April 2014). Participants were sent a panel of five slides and asked to return a routinely stained slide which was assessed for quality of preparation and staining. Response rate was 89.9% (400/445). For slide 1 (no parasites), 30.6% participants reported malaria, mostly Plasmodium falciparum. Only 11.0% participants reported slide 2 (Plasmodium malariae) correctly, 71.0% reported "malaria" or "Plasmodium falciparum" (considered acceptable). Slide 3 contained Plasmodium falciparum (109/μl) and Trypanosoma brucei brucei trypomastigotes: they were each reported by 32.5% and 16.5% participants respectively, 6.0% reported both. Slide 4 (Trypanosoma) was recognised by 44.9% participants. Slide 5 (Plasmodium ovale) was correctly reported by 6.2% participants, another 68.8% replied "malaria" or "Plasmodium falciparum" (considered acceptable). Only 13.6% of routine slides returned were correctly prepared and stained. The proportion of correct/acceptable scores for at least 4/5 slides was higher among EQA-experienced participants compared to first time participants (40.9% versus 22.4%, p = 0.001) and higher among those being trained microscopy including non-falciparum species and Trypanosoma was poor. Recent training and previous EQA participation were associated with a better performance.

    With the energy systems of many African countries dominated by fossil-fuel sources that are vulnerable to global price volatility, regional and intra-continental power systems with high shares of renewable energy can provide least-cost option to support continued economic growth and address the continent’s acute energy access problem. Unlocking Africa’s huge renewable energy potential could help to take many people out of poverty, while ensuring the uptake of sustainable technologies for the continent’s long-term development. The report examines the ''renewable scenario'' based on a modelling tool developed by IRENA and tested in cooperation with the South African National Energy Development Institute (SANEDI) and the Southern African Development Community (SADC). Initial results from the System Planning and Test (SPLAT) model show that the share of renewable technologies in Southern Africa could increase from the current 10% to as much as 46% in 2030, with 20% of decentralised capacity coming from renewable sources and nearly 80% of the envisaged capacity additions between 2010 and 2030 being provided by renewable energy technologies. Deployment and export of hydropower from the Democratic Republic of Congo’s Inga hydropower project to the SADC region would significantly reduce average electricity generation costs. Analysis using SPLAT – along with a similar model developed for West Africa – can provide valuable input for regional dialogue and energy projects such as the East and Southern Africa Clean Energy Corridor and the Programme for Infrastructure and Development in Africa (PIDA). IRENA, together with partner organisations, has started plans to set up capacity building and development support for energy system modelling and planning for greater integration of renewables in Africa. IRENA is also completing a similar model and study for East Africa and intends to extend this work to Central and North Africa.

  14. [African mobilization against AIDS. After the Kinshasa Conference].

    Science.gov (United States)

    Poissonnier, A

    The AIDS epidemic in Africa has become too massive to ignore. A sign of increasing awareness of the AIDS threat was the attendance of some 1200 participants at the 5th international conference on AIDS in Africa held in Kinshasa, Zaire, in October 1990. An African society to combat AIDS has been formed and is based in Nairobi. The new association will be responsible for organization of coming conferences to be held in Africa rather than in Europe. Sub-Saharan Africa contains less than 10% of the world's population but 2/3 of adult AIDS cases and almost 90% of maternal and child cases. The epidemic is even more worrisome because it has brought with it a recrudescence of other illnesses such as tuberculosis. The World Health Organization estimates that 5 million Africans were seropositive in 1990 vs 2.5 million in 1987. Predictions are necessary and allow planning to begin for the care of the 10 million orphans who will be found in Africa by the year 2000 and for other serious problems created by the disease. But the situation is already very dire. There has been a certain stabilization in the number of cases in countries such as that Congo, Zaire, or the Central African Republic. As yet the stabilization cannot be explained. The pessimistic view is that the pause results from a purely statistical phenomenon due to increased mortality. The optimistic view is that sexual behavior is responding to health information campaigns. Although the experts had expected the AIDS epidemic to be limited to urban zones in Africa, rural rates already approach urban rates in several countries such as the Ivory Coast, Tanzania, Uganda, and Rwanda. Mother-infant contamination is the greatest worry of health officials. The number of infants infected during pregnancy or birth is expected to double to 1 million by 1992 and reach nearly 10 million in 2000. Some 20-25 million Africans will be seropositive by 2000. A cure for AIDS is unlikely in the near future. Products delaying the onset of

    Human African trypanosomiasis or sleeping sickness is a neglected tropical disease that affects populations in sub-Saharan Africa. The disease is caused by infection with the gambiense and rhodesiense subspecies of the extracellular parasite Trypanosoma brucei, and is transmitted to humans by bites of infected tsetse flies. The disease evolves in two stages, the hemolymphatic and meningoencephalitic stages, the latter being defined by central nervous system infection after trypanosomal traversal of the blood-brain barrier. African trypanosomiasis, which leads to severe neuroinflammation, is fatal without treatment, but the available drugs are toxic and complicated to administer. The choice of medication is determined by the infecting parasite subspecies and disease stage. Clinical features include a constellation of nonspecific symptoms and signs with evolving neurological and psychiatric alterations and characteristic sleep-wake disturbances. Because of the clinical profile variability and insidiously progressive central nervous system involvement, disease staging is currently based on cerebrospinal fluid examination, which is usually performed after the finding of trypanosomes in blood or other body fluids. No vaccine being available, control of human African trypanosomiasis relies on diagnosis and treatment of infected patients, assisted by vector control. Better diagnostic tools and safer, easy to use drugs are needed to facilitate elimination of the disease.

    The African elephant consists of forest and savanna subspecies. Both subspecies are highly endangered due to severe poaching and habitat loss, and knowledge of their population structure is vital to their conservation. Previous studies have demonstrated marked genetic and morphological differences between forest and savanna elephants, and despite extensive sampling, genetic evidence of hybridization between them has been restricted largely to a few hybrids in the Garamba region of northeastern Democratic Republic of Congo (DRC). Here, we present new genetic data on hybridization from previously unsampled areas of Africa. Novel statistical methods applied to these data identify 46 hybrid samples--many more than have been previously identified--only two of which are from the Garamba region. The remaining 44 are from three other geographically distinct locations: a major hybrid zone along the border of the DRC and Uganda, a second potential hybrid zone in Central African Republic and a smaller fraction of hybrids in the Pendjari-Arli complex of West Africa. Most of the hybrids show evidence of interbreeding over more than one generation, demonstrating that hybrids are fertile. Mitochondrial and Y chromosome data demonstrate that the hybridization is bidirectional, involving males and females from both subspecies. We hypothesize that the hybrid zones may have been facilitated by poaching and habitat modification. The localized geography and rarity of hybrid zones, their possible facilitation from human pressures, and the high divergence and genetic distinctness of forest and savanna elephants throughout their ranges, are consistent with calls for separate species classification.

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

    On February 16, 1992, the Government of the Czech Republic sanctioned, by its Decree No. 112/82, its first Energy Policy. Since that time, a number of conditions have changed: first of all, there was the partition of the former Federal Czechoslovak Republic, then the privatization of most of energy producing corporations, the deregulation of a significant proportion of power and energy commodities, the decision to bring to an end the construction of the Temelin nuclear power station, the creation of conditions for the construction of the Ingoldstadt oil pipeline, etc. These steps, on which the final decisions have been made, have brought about the necessity of updating the existing general Energy Policy. The updated Energy Policy is based on the Programme Statement by the Government of the Czech Republic of July 1992, as well as on other materials associated with energy and power generation, either approved or negotiated by the Government, in particular the State Environmental Policy the Rules of the State Raw Materials Policy, the European Association Agreement, the European Energy Charter, the results of the Uruguayan Round of GATT, the Convention on Climate Changes, the Ecological Action Programme for central and East-European countries, and other international documents that have either been, or are likely to be sanctioned by the Czech Government (especially the European Energy Charter Treaty, and the protocol on Trans-boundary Air Pollution and on Further Reduction of Sulphur Oxide Emissions).

    2002-01-01

    To investigate the origin of the beta(A) and beta(S) genes in a Mexican population with African roots and a high frequency of hemoglobin S, we analyzed 467 individuals (288 unrelated) from different towns in the states of Guerrero and Oaxaca in the Costa Chica region. The frequency of the sickle-cell trait was 12.8%, which may represent a public health problem. The frequencies of the beta-haplotypes were determined from 350 nonrelated chromosomes (313 beta(A) and 37 beta(S)). We observed 15 different beta(A) haplotypes, the most common of which were haplotypes 1 (48.9%), 2 (13.4%), and 3 (13.4%). The calculation of pairwise distributions and Nei's genetic distance analysis using 32 worldwide populations showed that the beta(A) genes are more closely related to those of Mexican Mestizos and North Africans. Bantu and Benin haplotypes and haplotype 9 were related to the beta(S) genes, with frequencies of 78.8, 18.2, and 3.0%, respectively. Comparison of these haplotypes with 17 other populations revealed a high similitude with the population of the Central African Republic. These data suggest distinct origins for the beta(A) and beta(S) genes in Mexican individuals from the Costa Chica region.

    2009-03-01

    Full Text Available Abstract Background Updated, accurate and comprehensive information on the distribution of human African trypanosomiasis (HAT, also known as sleeping sickness, is critically important to plan and monitor control activities. We describe input data, methodology, preliminary results and future prospects of the HAT Atlas initiative, which will allow major improvements in the understanding of the spatial distribution of the disease. Methods Up-to-date as well as historical data collected by national sleeping sickness control programmes, non-governmental organizations and research institutes have been collated over many years by the HAT Control and Surveillance Programme of the World Health Organization. This body of information, unpublished for the most part, is now being screened, harmonized, and analysed by means of database management systems and geographical information systems (GIS. The number of new HAT cases and the number of people screened within a defined geographical entity were chosen as the key variables to map disease distribution in sub-Saharan Africa. Results At the time of writing, over 600 epidemiological reports and files from seventeen countries were collated and included in the data repository. The reports contain information on approximately 20,000 HAT cases, associated to over 7,000 different geographical entities. The oldest epidemiological records considered so far date back to 1985, the most recent having been gathered in 2008. Data from Cameroon, Central African Republic, Chad, Congo, Equatorial Guinea and Gabon from the year 2000 onwards were fully processed and the preliminary regional map of HAT distribution is presented. Conclusion The use of GIS tools and geo-referenced, village-level epidemiological data allow the production of maps that substantially improve on the spatial quality of previous cartographic products of similar scope. The significant differences between our preliminary outputs and earlier maps of HAT

    The experiences of Black lesbians highlight the unique circumstance found at the intersection of sexuality, race, and gender. However, most sexuality research tends to focus on White lesbians and White gay men, and most race research tends to focus on Black heterosexuals. Furthermore, research on the Black gay community tends to focus on those living in the Northeast or on the West Coast, neglecting experiences of those living in the more politically, socially, and religiously conservative South. This article draws on data obtained from semistructured interviews with 12 Black lesbians living in north central Florida, exploring their perspectives as they negotiate a social world of intersecting oppressions.

    Full Text Available Abstract Background Quinine is still recommended as an effective therapy for severe cases of Plasmodium falciparum malaria, but the parasite has developed resistance to the drug in some cases. Investigations into the genetic basis for quinine resistance (QNR suggest that QNR is complex and involves several genes, with either an additive or a pairwise effect. The results obtained when assessing one of these genes, the plasmodial Na+/H+ exchanger, Pfnhe-1, were found to depend upon the geographic origin of the parasite strain. Most of the associations identified have been made in Asian strains; in contrast, in African strains, the influence of Pfnhe on QNR is not apparent. However, a recent study carried out in Kenya did show a significant association between a Pfnhe polymorphism and QNR. As genetic differences may exist across the African continent, more field data are needed to determine if this association exists in other African regions. In the present study, association between Pfnhe and QNR is investigated in a series of isolates from central Africa. Methods The sequence analysis of the polymorphisms at the Pfnhe-1 ms4760 microsatellite and the evaluation of in vitro quinine susceptibility (by isotopic assay were conducted in 74 P. falciparum isolates from the Republic of Congo. Results Polymorphisms in the number of DNNND or NHNDNHNNDDD repeats in the Pfnhe-1 ms4760 microsatellite were not associated with quinine susceptibility. Conclusions The polymorphism in the microsatellite ms4760 in Pfnhe-1 that cannot be used to monitor quinine response in the regions of the Republic of Congo, where the isolates came from. This finding suggests that there exists a genetic background associated with geographic area for the association that will prevent the use of Pfnhe as a molecular marker for QNR. The contribution of Pfnhe to the in vitro response to quinine remains to be assessed in other regions, including in countries with different levels of

    Full Text Available The article analyses the problems of strategic governance and strategic management of the Czechoslovak Government, as well as the Government of the Czech Republic in the years 1989-2016. It seeks the causes and factors that have caused the low levels of strategic governance and strategic management at the level of the ministries of the Czech Republic. It examines the problem from genetic and historical perspective, and from the organizational and human capacity to exercise strategic governance. The study is based on two pieces of empirical research within the ministries of the Czech Republic. It identifies the main cause of failure of strategic governance and strategic management at the level of the central government of the Czech Republic. These include, in particular, the persistent distrust of the ideas of strategic governance and strategic management held by the right-wing governments and the generally low capacity of governments of the Czech Republic to engage in strategic governance. The organizational structure of the central state administration lacks the strategic units that generate ideas for supporting strategic governance. The empirical research of the ministries of the Czech Republic also revealed that policy workers in Czech ministries dedicate a large proportion of their work time to operational and administrative activities at the expense of analytical and strategic activities. The changes require implementation of reforms within the public administration, which (among other things will eliminate the existing causes and inhibiting factors regarding the lack of strategic governance in the Czech Republic.

    Full Text Available In 2014, 162 bird species were recorded during the bird ringing activities in Slovenia. Of 155 species, 62,275 birds were ringed, and 107 recoveries of birds ringed in Slovenia and found abroad, 148 foreign recoveries in Slovenia and 1395 local recoveries were recorded. The most frequently ringed species were Blackcap Sylvia atricapilla and Great Tit Parus major. As far as ringed nestlings are concerned, Great Tits and Barn Swalllows Hirundo rustica predominated. Considering the recoveries ringed of found birds abroad, the commonest were Black-headed Gulls Chroicocephalus ridibundus and Mute Swans Cygnus olor. The farthest recovery was a Barn Swallow Hirundo rustica found in the Democratic Republic of Congo (5171 km away. Among the more interesting finds was also the so far southernmost recovery of a Sand Martin Riparia riparia found in Israel. Let us also mention the first recovery of a Corncrake Crex crex, which bred and was ringed in 2013 at Planinsko polje (central Slovenia and was found in the 2014 breeding season in the Czech Republic. Among rare species, two Little Buntings Emberiza pusilla were caught and ringed. After nine years, the Roller Coracias garrulus bred again in Slovenia in 2014 and its nestlings were ringed. The paper also brings the description of the migration route of the first African migrant, the Black Stork Ciconia nigra, marked with a GPS/GSM telemetric device, which migrated across the Adriatic Sea, Sicily and Sahara to Nigeria.

    Full Text Available Chikungunya is an Aedes -borne disease characterised by febrile arthralgia and responsible for massive outbreaks. We present a prospective clinical cohort study and a retrospective serological study relating to a CHIK outbreak, in the Republic of Congo in 2011.We analysed 317 suspected cases, of which 308 (97.2% lived in the city of Brazzaville (66.6% in the South area. Amongst them, 37 (11.7% were CHIKV+ve patients (i.e., biologically confirmed by a real-time RT-PCR assay, of whom 36 (97.3% had fever, 22 (66.7% myalgia and 32 (86.5% arthralgia. All tested negative for dengue. The distribution of incident cases within Brazzaville districts was compared with CHIKV seroprevalence before the outbreak (34.4% in 517 blood donors, providing evidence for previous circulation of CHIKV. We applied a CHIK clinical score to 126 patients recruited within the two first day of illness (including 28 CHIKV+ves (22.2% with sensitivity (78.6% and specificity (72.4% values comparing with those of the referent study in Reunion Island. The negative predictive value was high (92%, but the positive predictive value (45% indicate poor potential contribution to medical practice to identify CHIKV+ve patients in low prevalence outbreaks. However, the score allowed a slightly more accurate follow-up of the evolution of the outbreak than the criterion "fever+arthralgia". The complete sequencing of a Congolase isolate (Brazza_MRS1 demonstrated belonging to the East/Central/South African lineage and was further used for producing a robust genome-scale CHIKV phylogenetic analysis.We describe the first Chikungunya outbreak declared in the Republic of Congo. The seroprevalence study conducted amongst blood donors before outbreak provided evidence for previous CHIKV circulation. We suggest that a more systematic survey of the entomological situation and of arbovirus circulation is necessary in Central Africa for better understanding the environmental, microbiological and

    The Observatoire Satellital des Forêts d'Afrique Centrale (OSFAC) based in Kinshasa, serves as the focal point of the GOFC-GOLD network for Central Africa. OSFAC's long term objective is building regional capacity to use remotely sensed data to map forest cover and forest cover change across Central Africa. OSFAC archives and disseminates satellite data, offers training in geospatial data applications in coordination with the University of Kinshasa, and provides technical support to CARPE partners. Forêts d'Afrique Centrale Évaluées par Télédétection (FACET) is an OSFAC initiative that implements the UMD/SDSU methodology at the national level and quantitatively evaluates the spatiotemporal dynamics of forest cover in Central Africa. The multi-temporal series of FACET data is a useful contribution to many projects, such as biodiversity monitoring, climate modeling, conservation, natural resource management, land use planning, agriculture and REDD+. I am working as Remote Sensing and GIS Officer in various projects of OSFAC. My activities include forest cover and lands dynamics monitoring in Congo Basin. I am familiar with the use of digital mapping software, GIS and RS (Arc GIS, ENVI and PCI Geomatica etc.), classification and spatial Analysis of satellite images, 3D modeling, etc. I started as an intern at OSFAC, Assistant Trainer (Professional Training) and Consultant than permanent employee since October 2009. To assist in the OSFAC activities regarding the monitoring of forest cover and the CARPE program in the context of natural resources management, I participated in the development of the FACET Atlas (Republic of Congo). I received data from Matt Hansen (map.img), WRI and Brazzaville (shapefiles). With all these data I draw maps of the ROC Atlas and statistics of forest cover and forest loss. We organize field work on land to collect data to validate the FACET product. Therefore, to assess forest cover in the region of Kwamouth and Kahuzi-Maiko Biega

  10. Human Seroprevalence indicating Hantavirus Infections in Tropical Rainforests of Côte d´Ivoire and Democratic Republic of Congo

    Directory of Open Access Journals (Sweden)

    Peter T Witkowski

    2015-05-01

    Full Text Available Hantaviruses are members of the Bunyaviridae family carried by small mammals and causing human hemorrhagic fevers worldwide. In Western Africa, where a variety of hemorrhagic fever viruses occurs, indigenous hantaviruses have been molecularly found in animal reservoirs such as rodents, shrews, and bats since 2006. To investigate the human contact to hantaviruses carried by these hosts and to assess the public health relevance of hantaviruses for humans living in the tropical rainforest regions of Western and Central Africa, we performed a cross-sectional seroprevalence study in the region of Taï National Park in Côte d´Ivoire and the Bandundu region near the Salonga National Park in the Democratic Republic of Congo. Serum samples were initially screened with enzyme-linked immunosorbent assays using nucleoproteins of several hantaviruses as diagnostic antigens. Positive results were confirmed by Western blotting and immunofluorescence testing.Seroprevalence rates of 3.9% (27/687 and 2.4% (7/295, respectively, were found in the investigated regions in Côte d´Ivoire and the Democratic Republic of Congo. In Côte d´Ivoire, this value was significantly higher than the seroprevalence rates previously reported from the neighboring country Guinea as well as from South Africa. Our study indicates an exposure of humans to hantaviruses in West and Central African tropical rainforest areas. In order to pinpoint the possible existence and frequency of clinical disease caused by hantaviruses in this region of the world, systematic investigations of patients with fever and renal or respiratory symptoms are required.

Ahora sabemos que el proyecto de desarmar a las regiones fue un fracaso. Conocer las causas de este revés es el principal objetivo de este artículo, tomando como materia de estudio al departamento de Guanajuato. Asimismo, se destaca que para entender la historia de las fuerzas militares de Guanajuato y del fallo del proceso de centralización castrense es necesario relacionar directamente el tema militar con otros aspectos de la estructura societal de Guanajuato, en particular su sistema político.Most of the delegates in the Constituent Congress of 1835-1836 supported the government's centralization and monopoly of the legitimate use of military force, with the exclusion of any other local or regional institution from its command and organization.

    Both the Czech Republic and Poland as former Communist countries, are transforming their economies from central planning to a free market. This applies equally to energy planning and because they are starting from the same point, they have come up with very comparable solutions despite strong cultural differences, so that the parallels are striking. This study analyzes the energy management in local authorities in Poland and the Czech Republic with the objective of better: identifying the current situation, identifying the opportunities for action both now and in an extended European Union, identifying the constraints that may hinder full integration of East European municipalities in European Union programmes, improve the integration of municipalities in the countries concerned in pan-European networks of municipalities interested in energy issues. The study reviews the powers and responsibilities of local authorities in the energy field and the institutional framework within which local authorities work. There are now 16 directly elected regional authorities in Poland and the local authorities have been restructured into two levels, the Powiad and the Gmina. Similarly, in the Czech Republic 14 elected regional authorities have been established. This document brings together 2 reports: the final report and the study report about the energy policies in Poland and in the Czech republic: structure of local government, general and institutional aspects, national political organisation, national administrative organisation, municipal role in production and distribution, regulation and planning, energy issues, energy management policies, specific aspects at local level etc... The conclusions from two review seminars (Jablonec nad Nison (Czech republic), 25-26 January 2001, and Bielsko Biala (Poland), 22-23 February 2001) and some fact files on 4 large Czech towns and 4 large Polish towns complete the study.

  16. Comparative Advertising in the Czech Republic: An Empirical Study

    Directory of Open Access Journals (Sweden)

    Petr Kral

    2016-12-01

    Full Text Available Comparative advertising had been traditionally banned in most EU countries and was allowed by the European law just relatively recently. That is why in the EU this form of advertising is relatively new, as opposed to the situation in the US, where comparative advertising has been widely used and well accepted by consumers for decades. The literature has been silent on the topic of the effectiveness of comparative advertising in the Czech Republic, as well as in other Central and Eastern European countries. The goal of this paper is to investigate the effectiveness of comparative advertising campaigns in the Czech Republic. Using an online survey with 160 Czech respondents, we found that the attitude towards comparative advertising is rather positive in the Czech Republic. We also identified that the gender of the recipient influences the general perception of comparative advertising. On the other hand, the age of the recipient does not seem to be a moderator of the attitude towards comparative advertising, in general. The results also do not signal any impact of the gender and the age of the recipient on the change of the perception of any of the brands involved in the campaign. Managerial implications target mainly marketing and advertising managers responsible for Central European markets.

    The north African country of Tunisia (632,387 square miles) consists largely of desert, with some rich farmlands and a rocky transitional zone. Despite the government's family planning efforts, the population grew from 5.6 million in 1975, to 7.2 million in 1985, and, with its 2.4% annual growth rate, is projected to reach 8.1 million by 1990. Tunisia's rural population decreased to 46% in 1985 as workers and their families moved into urban areas. 98% of the population is Arab-Berber; Arabic and French are the offical languages. The age-sex distribution is typical of developing countries; the median age has increased from 16.8 years in 1966 to 19.5 in 1950 and persons over age 60 have increased from 5.1% in 1956 to 6.7% in 1980. Tunisian families average 5.7 persons in rural areas, and 5.4 persons in urban one. Marriages are declining, polygamy is outlawed, and divorce, once easy, is more difficult and declining. At independence in 1956, only 15% of Tunisians were literate, now 85-90% of primary school age children are enrolled and literacy had risen to 53% in 1980. Women, once heavily veiled, now have full rights and access to education. More than 60 thousand new workers compete for the 40,000 new job openings each year. An estimated 7000 laborers found work in Europe in 1984. Women composed only 11% of the 1975 work force, but by 1980, held 20% of jobs, although they were mainly low paying positions. In 1980, 35% of the laborers worked in agriculture, 19% in industry, 17% in service industries, and 10% in construction. Agriculture and tourism have declined in recent years, contributing to social unrest, currency decline, and inflated wages and consumer prices.

    The paper grasps the present situation of economy and industry in Kazakhstan and studies a policy for developing the industrial machine manufacturing industry of the country. Since the independence in 1992, the country is now at the great turning point in politics, economy, society and industry. The country is forced to convert from the industrial structure of one local area where much of its own discretion had not been given under the economy system of power centralization to the industrial structure which meets the international economic market system as an independent country. Making good use of agricultural and industrial property in the former U.S.S.R., the country needs to export energy resource like oil, natural gas and coal, and abundant ore resource like iron and non-ferrous metal, which were added with values. As the technical base for it, fostering and strengthening of the industrial machine manufacturing industry is important. At present, the situation is that because of the economic sluggishness, the country cannot manufacture domestically even basic mechanical parts and simply-manufactured parts which are required by the domestic energy industry, machine manufacturing industry, and other industries. The technical program to be proposed by Japan is planned to be worked out later based on the basic research made in fiscal 1993. 6 figs., 14 tabs.

    A reliable identification of desert dust (DD) episodes over north-central Spain is carried out based on the AErosol RObotic NETwork (AERONET) columnar aerosol sun photometer (aerosol optical depth, AOD, and Ångström exponent, α) and European Monitoring and Evaluation Programme (EMEP) surface particulate-mass concentration (PMx, x = 10, 2.5, and 2.5-10 µm) as the main core data. The impact of DD on background aerosol conditions is detectable by means of aerosol load thresholds and complementary information provided by HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory Model) air mass back trajectories, MODIS (Moderate Resolution Imaging Spectroradiometer) images, forecast aerosol models, and synoptic maps, which have been carefully reviewed by a human observer for each day included in the DD inventory. This identification method allows the detection of low and moderate DD intrusions and also of mixtures of mineral dust with other aerosol types by means of the analysis of α. During the period studied (2003-2014), a total of 152 DD episodes composed of 418 days are identified. Overall, this means ˜ 13 episodes and ˜ 35 days per year with DD intrusion, representing 9.5 % days year-1. During the identified DD intrusions, 19 daily exceedances over 50 µg m-3 are reported at the surface. The occurrence of DD event days during the year peaks in March and June, with a marked minimum in April and lowest occurrence in winter. A large interannual variability is observed showing a statistically significant temporal decreasing trend of ˜ 3 days year-1. The DD impact on the aerosol climatology is addressed by evaluating the DD contribution in magnitude and percent (in brackets) for AOD, PM10, PM2.5, and PM2.5 - 10, obtaining mean values of 0.015 (11.5 %), 1.3 µg m-3 (11.8 %), 0.55 µg m-3 (8.5 %) and 0.79 µg m-3 (16.1 %), respectively. Annual cycles of the DD contribution for AOD and PM10 present two maxima - one in summer (0.03 and 2.4 µg m-3 for AOD in

    The Sinassi Batholith in the Central African Fold Belt (CAFB) of northern Cameroon represents the largest volume of plutonic rocks or granitoids massif of the Western Cameroonian Domain. It is made up dominantly of tonalite-trondhjemite-granodiorite (TTG) suite and lesser granite which are locally more or less deformed, and composed of varying proportions of quartz, plagioclase, K-feldspar, biotite, hornblende, sphene, magnetite, apatite and zircon. Major and trace element compositions of fifteen rock samples of granitoids (Djourdé granodiorite, Sinassi quartz diorite and orthogneisses groups) indicate that investigated rocks from the Sinassi Batholith are characterized by medium- to high-K calc-alkaline affinity and metaluminous I-type signature. In addition, their chondrite- and primitive mantle-normalized trace element patterns are strongly fractionated ((La/Yb)N = 2.96-61.40) and show respectively enrichment in LREE relative to HREE and enrichment in LILE compared to HFSE with moderate to slight negative Nb-Ta, Ti and Eu anomalies consistent with a continental magmatic arc setting related to a subduction zone. Geothermobarometric calculations using hornblende-plagioclase thermometry and aluminum-in-hornblende barometry on eleven rock samples indicate that plutons from Sinassi Batholith were emplaced at average temperatures and pressures ranging between 698 and 720 °C and 4.06-5.82 kbar (Djourdé granitoids), 698-728 °C and 4.04-5.34 kbar (Sinassi granitoids) and 667-670 and 4.23-4.76 kbar (orthogneisses group) respectively. The average emplacement depths estimates for the investigated granitoids is constrained at ca 16-18 km, indicating that at least 16 km of crustal rocks of the Sinassi Batholith must have been eroded or uplifted at approximately exhumation rates of 0.08-0.10 mm/year. Regardless of their Th/U ratios, geochronological results highlight three main events characterizing the Neoproterozoic tectonomagmatic evolution within the Sinassi Batholith

    ICT results was found only in areas with an L. loa Mf prevalence above 15%. In contrast, there was no association between ICT positivity and M. perstans prevalence (Spearman's rho = - 0.200; p = 0.747 and Mf density (Odds ratio = 1.8; 95%CI: 0.8-4.2; p = 0.192.This study has confirmed the strong association between the ICT positivity and L. loa intensity (Mf/ml of blood at the individual level. Furthermore, the study has demonstrated that ICT positivity is strongly associated with high L. loa prevalence. These results suggest that the main confounding factor for positive ICT test card results are high levels of L. loa. The findings may indicate that W. bancrofti is much less prevalent in the Central African region where L. loa is highly endemic than previously assumed and accurate re-mapping of the region would be very useful for shrinking of the map of LF distribution.

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

    The goal of this research is to describe and analyze Shanghai's fashion during Republic Period. Shanghai's fashion during Republic Period plays a special role in fashion history of China and Shanghai history. In the paper, three aspects including the fashion centre of China as well as Far East, men's fashion and women's fashion in Shanghai are discussed. The style, textiles, color, decoration and combination of clothing are described. Many costumes from the Clothing Museum at Donghua University and private collections as well as some historical writings, photographs and publications are elucidated and corroborated to give a more detailed description about Shanghai's fashion during that period.Here are some tentative conclusions. Firstly, Shanghai had always been the fashion center in China even Far East during Republic Period. Modeng was the main reflection of Shanghai fashion. Secondly, the traditional clothing exerted less influence and was less widely used, some kinds and combinations were out of fashion gradually. The fashion was described to be highly stylized, exquisite and concise. Thirdly, the influence of Western Style was further greater. The fashion in Shanghai was almost synchronous with fashion of Paris. Some western clothing was directly used in daily life and the elements of Western Style had an increasingly wide utilization. Fourthly, the New Chinese Style whose representatives were Qipao and Zhongshan Zhuang appeared and popularized in Shanghai. The fashion of Qipao changed frequently. Finally, the fashion in Shanghai called Shanghai Style could be summarized fashionable, exquisite, rapidly changeable, which is harmonious of both ancient and modern, Chinese and foreign.

    Full Text Available There is so much alienation, pain and suffering in our today�s world. In this vein, African Christianity, a voice amongst many voices, should seek to be a transformational religion for the whole of life, affecting all facets of human life towards a fuller life of all in Africa. This article sought to highlight and point to some of the major societal challenges in the African context which African Christianity, as a life-affirming religion, should continue to embrace, re-embrace and engage with, if it has to be relevant to the African context. In this vein, the article argued that a correct reading of the African context would lead to a more relevant theory and praxis of African Christianity for the benefit of all African peoples and their global neighbours. The contention of this article was that African Christianity has a significant role to play in the re-shaping of the African society and in the global community of humans, only that this role must be executed inclusively, responsibly and appropriately, together with all those who seek the holistic development of Africa towards one common destiny.

  11. The Republic of Panama.

    Science.gov (United States)

    1986-08-01

    Panama's open financial system, skilled labor force, adequate infrastructure, and export-oriented commercial sector give it a greater prospect for recovery from Latin America's economic crisis than other countries. Indicators such as average daily caloric rate, population per health care worker, per capita income, total fertility rate, life expectancy, and percent of population under 15 years are more favorable in Panama than neighboring countries. However, economic growth is at present being undermined by internal and external debt, unemployment, high labor costs, and a rising trade deficit. Real per capita output has stagnated since 1980 and growth in the gross domestic product stood at 4.4% in 1982. Over 60% of married women in Panama use modern contraceptive methods, making the birth rate of 28/1000 the lowest in Central America. Panama's growth rate is expected to be 1.9%/year until the year 2000, at which point the population is projected to be 3 million. The infant mortality rate was 26/1000 in 1985, comparable to that in developed countries. Of concern has been rapid urbanization. 54% of the total population in 1980 lived in urban areas, and 66% of the urban population is concentrated in Panama City. Another concern is the tremendous gap between the rich and the poor in Panama. In 1980, the poorest 20% of the population received only 2.7% of total income, while the richest 20% received 60.3%. Such inequality has been somewhat compensated for by above average health services, a national sanitation program to provide safe drinking water, and strong government support for public education. Female labor force participation rates are higher in urban areas, but tends to be concentrated in the low-paying service sector. To absorb additions to the labor force, the economy needs to grow by 7.5%/year.

    Full Text Available This paper summarizes current knowledge about Central African pholcids. Central Africa is here defined as the area between 10°N and 7°S and between 6°E and 18°E, including mainly the Lower Guinean subregion of the Guineo-Congolian center of endemism. This includes all of Gabon, Equatorial Guinea, São Tomé and Príncipe, most of Cameroon and Congo Republic, and parts of the neighboring countries. An annotated list of the 14 genera and 79 species recorded from this area is given, together with distribution maps and an identification key to genera. Seven species are newly described: Anansus kamwai sp. nov., Leptopholcus gabonicus sp. nov., Ninetis faro sp. nov., Pholcus punu sp. nov., P. rawiriae sp. nov., Spermophora abibae sp. nov., and S. awalai sp. nov. Additional new records are given for 16 previously described species, including 17 new country records. Distribution and diversity patterns are compared with data on West and East Africa. While West Africa contains a similar set of genera it is significantly less diverse than Central Africa. East Africa is taxonomically more distinct. It has similar levels of diversity as Central Africa, but appears to be less undersampled.

    1995-12-01

    The Czech Republic ranks among the countries with high total reserves of hard coal and lignite. Therefore coal always had and still has a significant role in covering the power demand of the Czech Republic. Transition of the national economy, based on the principles of the market economy and private ownership, affects among others also behavior of the mining companies. A strong emphasis is also aimed at the environmental aspects concerning both the process of coal mining and the process of its utilization. Within these intentions the power policy of the Czech Republic is formulated. The Czech Republic, which has 10 mil. inhabitants, ranks among the countries with a high share of industry in the process of creating the gross national product. This state has its historical roots as on the present territory of the Czech Republic there had been concentrated a majority of industrial and mining capacities of the Hapsburg Empire. The First World War resulted among others in the decline of the Hapsburg Empire. Within this process Czechoslovak Republic was established (apart from other things the center of democracy in the Central Europe). In that republic the industry had an important position. The industrial potential had been expanded even during the occupation of Czechoslovakia by Nazi Germany in the years 1939 - 1945. After the Second World War when Europe was divided into two political spheres Czechoslovakia became a significant industrial base of so called East Bloc. Such a development and the needs of the Eastern Bloc resulted in the intensive development of the heavy industry on the territory of Czechoslovakia.

    2012-01-01

    Against the background of the HIV epidemic and the intense public controversy on homosexuality in African societies, this article investigates the discourses of academic African Christian theologians on homosexuality. Distinguishing some major strands in African theology, that is, inculturation, liberation, women's and reconstruction theology, the article examines how the central concepts of culture, liberation, justice, and human rights function in these discourses. On the basis of a qualitative analysis of a large number of publications, the article shows that stances of African theologians are varying from silence and rejection to acceptance. Although many African theologians have taken up the cudgels against gay rights, some "dissident voices" break the taboo and develop more inclusive concepts of African identity and African Christianity.

  7. Kosovo - An Atypical Parliamentary Republic

    2016-07-01

    Full Text Available The topic of this comparative study is the republican character of the system of governance in Kosovo. In the public discourse and political communication, as well as in academic discourse Kosovo is considered a Parliamentary Republic, based on the principle “of the separation of powers and checks and balances between them.” Although the constitutional definition of the relationship between the executive and legislative favors parliamentary republicanism, the constitutional powers of the president, the government and especially the constitutional and political power of the prime minister, significantly weaken the parliamentary character, in favor of a semi-presidential system. However, neither the current theories of government, nor constitutional provisions can rank Kosovo among semi-presidential systems, or pure parliamentary systems. Comparisons of competence powers relations in Kosovo, with similar relations and competences of the countries of the region and beyond, testify to the specific nature of parliamentary democracy in Kosovo. It is precisely the comparison of the Kosovo constitutional-legal system of governance with similar systems and theoretical analysis of parliamentary models facing Kosovo model which will be the basis of support of the hypothesis that Kosovo is not a typical parliamentary republic.

  11. The Universal Jurisdiction of South African Criminal Courts and Immunities of Foreign State Officials

    Directory of Open Access Journals (Sweden)

    Evode

    2015-12-01

    Full Text Available Under the "complementarity" regime of the Rome Statute of the International Criminal Court (ICC, the jurisdiction of the ICC is secondary to the jurisdiction of domestic courts. States Parties, not the ICC, have the primary responsibility of investigating and prosecuting international crimes. The ICC acts only when States are "unable" or "unwilling" to prosecute. As a State Party, in order to give effect to the complementarity principle, South Africa enacted the Implementation of the Rome Statute of the International Criminal Court Act 27 of 2002, which determines the modalities of prosecuting perpetrators of the crimes of genocide, crimes against humanity and war crimes in South African courts. The Implementation Act also provides that South African courts will have jurisdiction over these crimes not only when they are committed on the territory of South Africa but also when they are committed outside the Republic. By granting South African courts jurisdiction over a person who commits a crime outside the Republic when that person is later found on South African territory, without regard to that person's nationality or the nationality of the victims, the Implementation Act empowers South African courts with universal jurisdiction over international crimes. This paper seeks to determine whether and to what extent foreign State officials, such as foreign heads of State, heads of government and ministers of foreign affairs, can plead immunity when they are accused of international crimes before South African courts when exercising their universal jurisdiction in terms of the Implementation Act and in accordance with the complementarity regime of the Rome Statute.

    Reimold, Wolf Uwe

    1999-10-01

    In contrast to Europe, where geoconservation is actively pursued in most countries and where two international symposia on this subject have been staged in 1991 and 1996, geoconservation in Africa has indeed a very poor record. Considering the wealth of outstanding geological sites and the importance African stratigraphy has within the global geological record, pro-active geoconservation on this continent has not featured very prominently to date. In the interest of science, education and tourism, unique and typical geosites need to be identified, catalogued, and prioritised with the aim being their protection. Most African countries do not have vibrant non-governmental organisations such as a strong geological society, which could drive projects like geoconservation, or strong support from the private sector for environmental work. Here, a case is made for the role that established National Geological Surveys, some of which are already involved with retroactive environmental geological work, could play in the forefront of pro-active geoconservation and site protection.

    Past disturbances have modified local density, structure and floristic composition of Central African rainforests. As such, these perturbations represent a driving force for forest dynamics and they were presumably at the origin of present-day forest mosaics. One of the most prominent disturbances within the forest is fire, leaving behind charcoal as a witness of past forest dynamics. Quantification and identification of ancient charcoal fragments found in soil layers (= pedoanthracology) allows a detailed reconstruction of forest history, including the possible occurrence of past perturbations. The primary objective of this study is to present palaeoenvironmental evidence for the existence of past disturbances in the forests of the Kisangani region (Democratic Republic of the Congo) using a pedoanthracological approach. We quantified and identified charcoal fragments from pedoanthracological excavations in the Yangambi, Yoko, Masako and Kole forest regions. Charcoal sampling was conducted in pit intervals of 10 cm, whereby pottery fragments were also registered and quantified. Floristic identifications were conducted using former protocols based on wood anatomy, which is largely preserved after charcoalification. 14 excavations were conducted and charcoal was found in most pit intervals. Specifically, 52 out of 56 sampled intervals from the Yangambi forest contained charcoal, along with 47 pit intervals from the Yoko forest reserve, 34 pit intervals from the Masako forest and 16 from the Kole forest. Highest specific anthracomasses were recorded in Yoko (167 mg charcoal per kg soil), followed by Yangambi (133 mg/kg), Masako (71,89 mg/kg) and finally Kole (42,4 mg/kg). Charcoal identifications point at a manifest presence of the family of Fabaceae (Caesalpinioideae). This family is characteristic for the tropical humid rainforest. The presence of charcoal fragments from these taxa, associated with pottery sherds on different depths within the profiles, suggests

    Full Text Available Being interested in African literature one seems to swim from the very beginning in a terminological maelstrom. What is African literature? Is it literature written by any African author in any language? That would mean approaching the question from a purely racial basis. It would imply the art of demonstrating that any piece of such literature could infallibly be recognised as African, a thing which, as far as I know has never been done. Or is African literature strictly bound to traditional African culture?

In the Republic of Congo (Congo-Brazzaville its bark is anecdotally reported to provide human protection against fleas. Here we assess the insecticidal activities of Z. heitzii stem bark, seed and leaf extracts against Anopheles gambiae s.s, the main malaria vector in Africa. Extracts were obtained by Accelerated Solvent Extraction (ASE using solvents of different polarity and by classical Soxhlet extraction using hexane as solvent. The insecticidal effects of the crude extracts were evaluated using topical applications of insecticides on mosquitoes of a susceptible reference strain (Kisumu [Kis], a strain homozygous for the L1014F kdr mutation (kdrKis, and a strain homozygous for the G119S Ace1R allele (AcerKis. The insecticidal activities were measured using LD50 and LD95 and active extracts were characterized by NMR spectroscopy and HPLC chromatography. Results show that the ASE hexane stem bark extract was the most effective compound against An. gambiae (LD50 = 102 ng/mg female, but was not as effective as common synthetic insecticides. Overall, there was no significant difference between the responses of the three mosquito strains to Z. heitzii extracts, indicating no cross resistance with conventional pesticides.

  1. Structural analysis of the 5 prime flanking region of the. beta. -globin gene in African sickle cell anemia patients: Further evidence for three origins of the sickle cell mutation in Africa

    Energy Technology Data Exchange (ETDEWEB)

    Chebloune, Y.; Pagnier, J.; Trabuchet, G.; Faure, C.; Verdier, G.; Labie, D.; Nigon, V. (Universite Claude Bernard-Lyon, Villeurbane (France))

    1988-06-01

    Haplotype analysis of the {beta}-globin gene cluster shows two regions of DNA characterized by nonrandom association of restriction site polymorphisms. These regions are separated by a variable segment containing the repeated sequences (ATTTT){sub n} and (AT){sub x}T{sub y}, which might be involved in recombinational events. Studies of haplotypes linked to the sickle cell gene in Africa provide strong argument for three origins of the mutation: Benin, Senegal, and the Central African Republic. The structure of the variable segment in the three African populations was studied by S1 nuclease mapping of genomic DNA, which allows a comparison of several samples. A 1080-base-pair DNA segment was sequenced for one sample from each population. S1 nuclease mapping confirmed the homogeneity of each population with regard to both (ATTTT){sub n} and (AT){sub x}T{sub y} repeats. The authors found three additional structures for (AT){sub x}T{sub y} correlating with the geographic origin of the patients. Ten other nucleotide positions, 5{prime} and 3{prime} to the (AT){sub x}T{sub y} copies, were found to be variable when compared to homologous sequences from human and monkey DNAs. These results allow us to propose an evolutionary scheme for the polymorphisms in the 5{prime} flanking region of the {beta}-globin gene. The results strongly support the hypothesis of three origins for the sickle mutation in Africa.

    The habitats of Biomphalaria straminea, the intermediate host of Schistosoma mansoni, have been found in Hong Kong Special Administrative Region and Shenzhen City of People's Republic of China. Currently, there is a sharp increase in the number of Africa-aid projects and workers moving to Africa, and more and more cases infected with S. mansoni or S. haematobium returning from African countries have been detected in China. The possibility of transmission of African schistosomiasis in Chinese mainland, in the context of global climate warming, has received much attention. This paper illustrates the risk of transmission of African schistosomiasis in China based on biological and epidemiological features, and proposes interventions to tackle the risk.

  14. Republic of Ireland: abortion controversy.

    Science.gov (United States)

    1998-01-01

    The problems associated with illegal abortion dominate public discussion in Ireland. While abortion is illegal in Ireland, the Supreme Court directed in 1992 that Irish women can go to Britain for abortions when their lives are thought to be at risk. Abortion was a constant feature during the Irish Presidential election campaign in October, while a dispute about the future of a 13-year-old girl's pregnancy dominated the headlines in November. The presidential election on October 30 resulted in a victory for one of the two openly anti-choice candidates, Mary McAleese, a lawyer from Northern Ireland. With a voter turnout of 47.6%, McAleese polled 45.2% of the votes cast. Although the president may refuse to sign bills which have been passed by parliament, McAleese has said that she will sign whatever bill is placed before her, even if it liberalizes abortion law in the republic. As for the case of the 13-year-old pregnant girl, she was taken into the care of Irish health authority officials once the case was reported to the police. However, the health board, as a state agency, is prevented by Irish law from helping anyone travel abroad for abortion. The girl was eventually given leave in a judgement by a High Court Judicial Review on November 28 to travel to England for an abortion.

    Full Text Available The Democratic Republic of Congo (DRC is the second largest country on the African continent with a population of over 70 million. It is also a major crossroad through Africa as it borders nine countries. Unfortunately, the DRC has experienced recurrent political and social instability throughout its history and active fighting is still prevalent today. At least two decades of conflict have devastated the civilian population and collapsed healthcare infrastructure. Life expectancy is low and government expenditure on health per capita remains one of the lowest in the world. Emergency Medicine has not been established as a specialty in the DRC. While the vast majority of hospitals have emergency rooms or salle des urgences, this designation has no agreed upon format and is rarely staffed by doctors or nurses trained in emergency care. Presenting complaints include general and obstetric surgical emergencies as well as respiratory and diarrhoeal illnesses. Most patients present late, in advanced stages of disease or with extreme morbidity, so mortality is high. Epidemics include HIV, cholera, measles, meningitis and other diarrhoeal and respiratory illnesses. Lack of training, lack of equipment and fee-for-service are cited as barriers to care. Pre-hospital care is also not an established specialty. New initiatives to improve emergency care include training Congolese physicians in emergency medicine residencies and medic ranger training within national parks.

  16. Central centrifugal cicatricial alopecia.

    Whiting, David A; Olsen, Elise A

    2008-01-01

    A progressive scarring alopecia of the central scalp is commonly seen in young to middle-aged females of African descent. It usually starts at the vertex or mid top of the scalp and gradually spreads centrifugally, hence, the unifying term of central centrifugal cicatricial alopecia. The clinical pattern is suggestive of female pattern alopecia, but a lack of follicular pores indicative of scarring is present. It can progress for years before slowly burning out. The etiology is unknown but genetic factors may be important. It is often associated with a history of traumatic hairstyling involving heat, traction, and chemicals. However, most patients of African descent without this disorder have similar styling habits. Nonetheless, avoidance of physical and chemical trauma to the scalp hair, the use of suitable shampoos and conditioners, and the encouragement of natural hairstyles may be helpful. Any infection should be treated. Topical or intralesional corticosteroids and systemic antibiotics may be useful and topical minoxidil should be tried with the hope of preventing further scarring and encouraging regrowth of recovering follicles. Current research into the etiology of this disorder will help to foster much-needed clinical trials of therapeutic agents.

    Full Text Available The expansion of the European Union (EU and economic growth have propelled the development of intermodal transportation and logistics activities in Central and Eastern Europe (CEE. Yet, the inland location of most CEE economies requires improved connectivity to port terminals on both the Atlantic/Baltic and Mediterranean/Black Sea ranges. The paper provides a broader research perspective on inland logistics platforms focusing on the CEE region, particularly as it concerns the role of the public sector in port hinterland infrastructure development. The paper identifies the current bottlenecks in logistics activity in regard to the whole range of the national transport chains. A dual regionalization process is taking place between the ports of the Northern and Mediterranean ranges and that the Northern Range is more effective at servicing the CEE region, including the Czech Republic, in spite of the proximity advantage of Mediterranean ports.

Within rural tourism, agritourism has been developed in these countries as a particular subset, and its significant enhancement in post-socialist European countries was widely anticipated (especially after their integration into the European Union. While considerable and focused attention was devoted to the implementation of agritourism strategies and the characterization of agritourist space with respect to particular countries (e.g. Poland and Slovenia, in Czech geographical literature it has remained a noticeably absent topic. In this paper, central attention is paid to selected characteristics of agritourist space in the Czech Republic, analyzed on the basis of a compiled database of farms diversified into tourism at the municipality level.

The last category is more appropriately considered as part of the civil-military and foreign policy history of the Republic of South Africa because of the severance of the Commonwealth tie in 1961 and the declaration of the arms embargo against the Republic in 1963.

However, the scarcity of organs appropriate for transplantation has led to an organ shortage crisis. This article retrospectively reviews strategies to change negative public attitudes toward organ donation in the People's Republic of China. We strongly believe that efforts to publicize knowledge of organ donation, promote family discussions, train medical staff and students, establish incentive systems, and implement regulatory oversight may combat unfavorable Chinese public opinion toward organ donation and transplantation, thus potentially increasing the organ donation rate in the People's Republic of China.

    Full Text Available Privatisation of the banking sector is an inseparable part of development strategies used by the countries in transition. The process of transition and building a financial and market-oriented system is a complex and long-term task which, in addition to a variety of legal arrangements, involves also several institutional options, such as the Central Bank of Bosnia and Herzegovina, Banking Agency of the Republic of Srpska and Banja Luka Stock Exchange of Securities. The transition process of the banking sector in the Republic of Srpska was not implemented by rehabilitation of existing domestic banks, but by opening the banking system for the entry of foreign, more efficient banks. The level of trust in the banking sector grew in parallel with the process of bank privatisation and the arrival of foreign banks. Throughout the previous period, all the banks in the Republic of Srpska recorded a significant increase in the amount of deposits and loans placed, which implies the growth of investment and economic activities, therefore indicating the increase of the Republic of Srpska’s GDP in general. These are positive trends that demonstrate a decrease in the current lagging behind the European Union.

  9. Aspects of size and geography of an African cyberspace

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

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

    Directory of Open Access Journals (Sweden)

    2007-12-01

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

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

  13. Permanent sample plots for natural tropical forests: a rationale with special emphasis on Central Africa.

    Permanent sample plots (PSP), where trees are individually and permanently marked, have received increased interest in Central Africa as a tool to monitor vegetation changes. Although techniques for mounting PSP in tropical forests are well known, their planning still deserves attention. This study aims at defining a rationale for determining the size and number of replicates for setting up PSP in mixed tropical forests. It considers PSP as a sampling plan to estimate a target quantity with its associated margin of error. The target quantity considered here is the stock recovery rate, which is a key parameter for forest management in Central Africa. It is computed separately for each commercial species. The number of trees to monitor for each species defines the margin of error on the stock recovery rate. The size and number of replicated plots is obtained as the solution of an optimization problem that consists in minimizing the margin of error for every species while ensuring that the mounting cost remains below a given threshold. This rationale was applied using the data from the M'Baïki experimental site in the Central African Republic. It showed that the stock recovery rate is a highly variable quantity, and that the typical cost that forest managers are prone to devote to PSP leads to high margins of error. It also showed that the size and number of replicated plots is related to the spatial pattern of trees: clustered or spatially heterogeneous patterns favor many small plots, whereas regular or spatially homogeneous patterns favor few large plots.

    2014-01-01

    Since entering into EU ten years ago, Poland, the Czech Republic, Slovakia and Hungary, the four members of Visegrad Group, have benefited greatly: rapid growth of total GDP and per capita GDP, export expansion, reduction of gap with old EU members in income and price level and improvement of quality of life in most member nations. However, these countries have not achieved the goal of reaching the living standard of Western Europe. Take the Czech Republic as an example: after entering into the EU, the Czech Republic does not have an economic convergence with the EU mainly because of its two economic recessions, its failures in absorbing EU funds and conducting EU policies consistently. Meanwhile, despite concerns for negative impacts of entering into EU, they have not occurred yet.%入盟十年来,欧盟成员国身份给中欧维谢格拉德集团四国波兰、捷克、斯洛伐克和匈牙利带来了一系列的好处:促进国内生产总值和人均国内生产总值快速增长,出口扩大,与欧盟老成员国之间收入和物价水平的差距有所缩小,多数成员国生活质量显著改善。但这些国家达到西欧发达国家生活水平的美好愿望并没有实现。以捷克为例,入盟后经历了两次经济衰退、吸收欧盟基金不力和对欧盟的政策不连续等因素是造成其与欧盟经济趋同效果不佳的主要原因。与此同时,他们曾经担忧的入盟消极影响也没有变成现实。

  2. Diversity among African pygmies.

    Directory of Open Access Journals (Sweden)

    Fernando V Ramírez Rozzi

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

  3. A tsetse and tabanid fly survey of African great apes habitats reveals the presence of a novel trypanosome lineage but the absence of Trypanosoma brucei.

    Tsetse and tabanid flies transmit several Trypanosoma species, some of which are human and livestock pathogens of major medical and socioeconomic impact in Africa. Recent advances in molecular techniques and phylogenetic analyses have revealed a growing diversity of previously unidentified tsetse-transmitted trypanosomes potentially pathogenic to livestock and/or other domestic animals as well as wildlife, including African great apes. To map the distribution, prevalence and co-occurrence of known and novel trypanosome species, we analyzed tsetse and tabanid flies collected in the primary forested part of the Dzanga-Sangha Protected Areas, Central African Republic, which hosts a broad spectrum of wildlife including primates and is virtually devoid of domestic animals. Altogether, 564 tsetse flies and 81 tabanid flies were individually screened for the presence of trypanosomes using 18S rRNA-specific nested PCR. Herein, we demonstrate that wildlife animals are parasitized by a surprisingly wide range of trypanosome species that in some cases may circulate via these insect vectors. While one-third of the examined tsetse flies harbored trypanosomes either from the Trypanosoma theileri, Trypanosoma congolense or Trypanosoma simiae complex, or one of the three new members of the genus Trypanosoma (strains 'Bai', 'Ngbanda' and 'Didon'), more than half of the tabanid flies exclusively carried T. theileri. To establish the putative vertebrate hosts of the novel trypanosome species, we further analyzed the provenance of blood meals of tsetse flies. DNA individually isolated from 1033 specimens of Glossina spp. and subjected to high-throughput library-based screening proved that most of the examined tsetse flies engorged on wild ruminants (buffalo, sitatunga, bongo), humans and suids. Moreover, they also fed (albeit more rarely) on other vertebrates, thus providing indirect but convincing evidence that trypanosomes can be transmitted via these vectors among a wide range of

    2010-07-01

    The Great Lakes region of Central Africa is a major producer of common beans in Africa. The region is known for high population density and small average farm size. The common bean represents the most important legume crop of the region, grown on over a third of the cultivated land area, and the per capita consumption is among the highest in the world for the food crop. The objective of this study was to evaluate the genetic diversity in a collection of 365 genotypes from the Great Lakes region of Central Africa, including a large group of landraces from Rwanda as well as varieties from primary centers of diversity and from neighboring countries of Central Africa, such as the Democratic Republic of Congo and Uganda, using 30 fluorescently labeled microsatellite markers and automated allele detection. In addition, the landraces were evaluated for their seed iron and zinc concentration to determine if genetic diversity influenced nutritional quality. Principal coordinate and neighbor-joining analyses allowed the separation of the landraces into 132 Andean and 195 Mesoamerican (or Middle American) genotypes with 32 landraces and 6 varieties intermediate between the gene pools and representing inter-gene pool introgression in terms of seed characteristics and alleles. Genetic diversity and the number of alleles were high for the collection, reflecting the preference for a wide range of seed types in the region and no strong commercial class preference, although red, red mottled and brown seeded beans were common. Observed heterozygosity was also high and may be explained by the common practice of maintaining seed and plant mixtures, a coping strategy practiced by Central African farmers to reduce the effects of abiotic and biotic stresses. Finally, nutritional quality differed between the gene pools with respect to seed iron and zinc concentration, while genotypes from the intermediate group were notably high in both minerals. In conclusion, this study has shown that

    2016-03-01

    Full Text Available The National Bank of the Republic of Moldova, as well as other central banks from other neighbouring countries, with the view to promoting the monetary policy, replaced the objective „ achieving and maintaining the national currency stability” with the target “ensuring and maintaining price stability”. This adjustment conditioned the selection of an optimal monetary policy regime to achieve the respective aim. Further to analysis and research there has been adopted the inflation targeting regime in order to determine the exact amount to a variation interval on a 24 month range. Relying on the experience in implementing the inflation targeting regime by the National Bank of Moldova it was determined that this monetary policy regime is the most adequate for the present socio-economic development of the Republic of Moldova.

    2013-03-01

    In this paper, repeated measurements of radon progeny concentration in dwellings in the Czech Republic are described. Two distinct data sets are available: one based on present measurements in 170 selected dwellings in the Central Bohemian Pluton with a primary measurement carried out in the 1990s and the other based on 1920 annual measurements in 960 single-family houses in the Czech Republic in 1992 and repeatedly in 1993. The analysis of variance model with random effects is applied to data to evaluate the variability of measurements. The calculated variability attributable to repeated measurements is compared with results from other countries. In epidemiological studies, ignoring the variability of measurements may lead to biased estimates of risk of lung cancer.

    1998-01-01

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

  1. The continuing problem of human African trypanosomiasis (sleeping sickness).

    Science.gov (United States)

    Kennedy, Peter G E

    2008-08-01

    Human African trypanosomiasis, also known as sleeping sickness, is a neglected disease, and it continues to pose a major threat to 60 million people in 36 countries in sub-Saharan Africa. Transmitted by the bite of the tsetse fly, the disease is caused by protozoan parasites of the genus Trypanosoma and comes in two types: East African human African trypanosomiasis caused by Trypanosoma brucei rhodesiense and the West African form caused by Trypanosoma brucei gambiense. There is an early or hemolymphatic stage and a late or encephalitic stage, when the parasites cross the blood-brain barrier to invade the central nervous system. Two critical current issues are disease staging and drug therapy, especially for late-stage disease. Lumbar puncture to analyze cerebrospinal fluid will remain the only method of disease staging until reliable noninvasive methods are developed, but there is no widespread consensus as to what exactly defines biologically central nervous system disease or what specific cerebrospinal fluid findings should justify drug therapy for late-stage involvement. All four main drugs used for human African trypanosomiasis are toxic, and melarsoprol, the only drug that is effective for both types of central nervous system disease, is so toxic that it kills 5% of patients who receive it. Eflornithine, alone or combined with nifurtimox, is being used increasingly as first-line therapy for gambiense disease. There is a pressing need for an effective, safe oral drug for both stages of the disease, but this will require a significant increase in investment for new drug discovery from Western governments and the pharmaceutical industry.

  5. Understanding the Rise of African Business

    DEFF Research Database (Denmark)

    Jorem, Kaja Tvedten; Jeppesen, Søren; Hansen, Michael W.

    In light of recent enthusiasm over the African private sector, this paper reviews the existing empirical literature on successful African enterprises and proposes an analytical framework for understanding African firm success. Overall, it is argued that we need to develop an understanding...... of African firm strategy and performance that takes into account the specificities of the African business environment and African firm capabilities. The paper starts by juxtaposing the widespread pessimistic view of African business with more recent, optimistic studies on African firms’ performance....... The latter suggests that profound improvements in African business performance are indeed under way: with the private sector playing a more important role as an engine of growth, with the rise of a capable African entrepreneurial class, and with the emergence of dynamic and competitive African enterprises...

  6. The history of African trypanosomiasis

    2008-02-01

    Full Text Available Abstract The prehistory of African trypanosomiasis indicates that the disease may have been an important selective factor in the evolution of hominids. Ancient history and medieval history reveal that African trypanosomiasis affected the lives of people living in sub-Saharan African at all times. Modern history of African trypanosomiasis revolves around the identification of the causative agents and the mode of transmission of the infection, and the development of drugs for treatment and methods for control of the disease. From the recent history of sleeping sickness we can learn that the disease can be controlled but probably not be eradicated. Current history of human African trypanosomiasis has shown that the production of anti-sleeping sickness drugs is not always guaranteed, and therefore, new, better and cheaper drugs are urgently required.

    Conclusion: The results indicate that there was little difference in African American perceptions of violence in Cincinnati in 2001 and 11 years later in 2012. Most people felt that violence in Cincinnati is a very serious problem, with more than half of the respondents indicating that in the past 3 years violence in Cincinnati stayed the same. More importantly, these findings emphasize that the riots in Cincinnati is not a central event in the African American community, instead for some, it represents another example of why violence always seem to exist and there is a low morale among the African American community and police officers.

    Full Text Available Ebola and Marburg viruses (family Filoviridae, genera Ebolavirus and Marburgvirus cause haemorrhagic fevers in humans, often associated with high mortality rates. The presence of antibodies to Ebola virus (EBOV and Marburg virus (MARV has been reported in some African countries in individuals without a history of haemorrhagic fever. In this study, we present a MARV and EBOV seroprevalence study conducted amongst blood donors in the Republic of Congo and the analysis of risk factors for contact with EBOV.In 2011, we conducted a MARV and EBOV seroprevalence study amongst 809 blood donors recruited in rural (75; 9.3% and urban (734; 90.7% areas of the Republic of Congo. Serum titres of IgG antibodies to MARV and EBOV were assessed by indirect double-immunofluorescence microscopy. MARV seroprevalence was 0.5% (4 in 809 without any identified risk factors. Prevalence of IgG to EBOV was 2.5%, peaking at 4% in rural areas and in Pointe Noire. Independent risk factors identified by multivariate analysis were contact with bats and exposure to birds.This MARV and EBOV serological survey performed in the Republic of Congo identifies a probable role for environmental determinants of exposure to EBOV. It highlights the requirement for extending our understanding of the ecological and epidemiological risk of bats (previously identified as a potential ecological reservoir and birds as vectors of EBOV to humans, and characterising the protection potentially afforded by EBOV-specific antibodies as detected in blood donors.

    In the developing world astronomy had been treated as the science of elites. As a result of this overwhelming perception, astronomy compared with other applied sciences has got less attention and its role in development has been insignificant. However, the IAU General Assembly decision in 2009 opened new opportunity for countries and professionals to deeply look into Astronomy and its role in development. Then, the subsequent establishment of regional offices in the developing world is helping countries to integrate astronomy with other earth and space based sciences so as to progressively promote its scientific and development importance. Gradually nations have come to know that space is the frontier of tomorrow and the urgency of preeminence on space frontier starts at primary school and ascends to tertiary education. For this to happen, member nations in east African region have placed STEM education at the center of their education system. For instance, Ethiopian has changed University enrollment strategy to be in favor of science and engineering subjects, i.e. every year seventy percent of new University entrants join science and engineering fields while thirty percent social science and humanities. Such bold actions truly promote astronomy to be conceived as gateway to science and technology. To promote the concept of astronomy for development the East African regional office has actually aligned it activities to be in line with the focus areas identified by the IAU strategy (2010 to 2020).

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

    The attenuated African swine fever virus genotype I strain OURT88/3 has previously been shown to induce protection of European breeds of domestic pigs against challenge with virulent isolates. To determine whether protective immune responses could also be induced in indigenous breeds of pigs from the Kinshassa region in Democratic Republic of Congo, we immunized a group of eight pigs with OURT88/3 strain and challenged the pigs 3 weeks later with virulent genotype I strain OURT88/1. Four of the pigs were protected against challenge. Three of the eight pigs died from African swine fever virus and a fourth from an unknown cause. The remaining four pigs all survived challenge with a recent virulent genotype I strain from the Democratic Republic of Congo, DRC 085/10. Control groups of non-immune pigs challenged with OURT88/1 or DRC 085/10 developed signs of acute ASFV as expected and had high levels of virus genome in blood.

    1999-11-01

    When looking at environmental health risks in the Karelian Republic from the viewpoint of environmental history, the cause and effect relationships of present environmental health risks can be comprehensively understood. The decrease experienced in drinking water quality, which has been induced by the extensive environmental changes, has been exposing the Karelian population to significant health risks. Several waterborne gastrointestinal epidemics witnessed in the Republic and the excess cancer risk of strongly chlorinated humus-rich drinking water are, together with the industrial and traffic and pollution, the most significant environmental health risks in the Karelian Republic today. In order to diminish the health risks related to drinking water, the use of surface water bodies as a drinking water source should be restricted and the so called shallow ground water sources, located near the settlements should be taken into use. In those locations where the water supply cannot be solely based on ground water resources, the raw water intake site should at least be moved further away from polluted water areas. (orig.)

    2012-08-01

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

    African swine fever is widespread in Africa but has occasionally been introduced into other continents. In June 2007, African swine fever was isolated in the Caucasus Region of the Republic of Georgia and subsequently in neighboring countries (Armenia, Azerbaijan, and 9 states of the Russian Federation). Previous data for sequencing of 3 genes indicated that the Georgia 2007/1 isolate is closely related to isolates of genotype II, which has been identified in Mozambique, Madagascar, and Zambia. We report the complete genomic coding sequence of the Georgia 2007/1 isolate and comparison with other isolates. A genome sequence of 189,344 bp encoding 166 open reading frames (ORFs) was obtained. Phylogeny based on concatenated sequences of 125 conserved ORFs showed that this isolate clustered most closely with the Mkuzi 1979 isolate. Some ORFs clustered differently, suggesting that recombination may have occurred. Results provide a baseline for monitoring genomic changes in this virus.

    Full Text Available David A Priilaid1, Paul van Rensburg21School of Management Studies, 2Department of Finance and Tax, University of Cape Town, Republic of South AfricaAbstract: With a sample of South African red and white wines, this paper investigates the relationship between price, value, and value for money. The analysis is derived from a suite of regression models using some 1358 wines drawn from the 2007 period, which, along with red and white blends, includes eight cultivars. Using the five-star rating, each wine was rated both sighted and blind by respected South African publications. These two ratings were deployed in a stripped-down customer-facing hedonic price analysis that confirms (1 the unequal pricing of consecutive increments in star-styled wine quality assessments and (2 that the relationship between value and price can be better estimated by treating successive wine quality increments as dichotomous “dummy” variables. Through the deployment of nonlinear hedonic pricing, fertile areas for bargain hunting can thus be found at the top end of the price continuum as much as at the bottom, thereby assisting retailers and consumers in better identifying wines that offer value for money.Keywords: price, value, wine

    Full Text Available I argue that the strict account of techne agreed to by Socrates and Thrasymachus in Republic I provides a useful framework for addressing a central question of the dialogue as a whole: how philosophy might belong to the polis. This view depends upon three positions: 1 that Plato invites us to interpret the relationship between techne and polis outside the terms of the city-soul analogy, 2 that the strict account contributes to a compelling description of vocational work, and 3 that this description determines what Socrates means by a true polis, and thus frames the problem of philosophy’s political inclusion.

    Full Text Available This essaic-article goes against established conventions that there is anything ethno-cultural (and hence national about the so-called African tribes. Drawing largely from the culture history of precolonial/prepolitical Africans—that is, the Bantu/Cushitic-Ethiopians (Azanians—the author has demonstrated vividly that far from being distinct ethno-culture national communities, the so-called tribes of African states are better considered subculture groups, whose regional culture practices erstwhile paid tribute to their nation’s main culture center in Karnak. For example, using the culture symbols and practices of some local groups and linking them to the predynastic and dynastic Pharaonic periods, I argued that there is compelling evidence against qualifying Africa’s tribes as distinct ethno-culture national entities. In genuine culture context, I stressed that the Ritual of Resurrection and its twin culture process of the mummification of deceased indigenous Pharaohs tend to suggest that the object of the Bantu/Cushitic-Ethiopians national culture was life (in its eternal manifestation and then resurrection later, and that there are recurring (culturally sanctioned ethical examples among the culture custodians of these subculture groups that generally pay tribute to the overarching culture norm. Furthermore, the fact that the Ritual of Resurrection began in the Delta region and ended at the Sources of the Nile, where the spirit of the deceased indigenous Pharaohs was introduced into the spiritual world of their ancestors, contradicts conventional perceptions that ancient Egypt was a distinct national community isolated from precolonial/prepolitical Africa/Azania.

    We present an analysis of the summer heat wave of August 2012 in the Czech Republic. We use and compare results of two different approaches to heat wave evaluation. The Weather Extremity Index evaluates the extremity and spatial extent of the meteorological extreme event of interest. The second method is based on the duration of daily maximum air temperature above specific thresholds. In August 2012, the high air temperature in the Czech Republic lasted from 18/8 to 24/8. It was connected with the inflow of hot air from northern Africa between the low pressure trough over the eastern Atlantic and the region of high pressure in central Europe. The heat wave culminated on 20/8 when the maximum air temperature was higher than 30°C in the whole area of the Czech Republic and the highest daily maximum air temperature on record in the Czech Republic with value of 40.4°C was observed at Dobřichovice station. Our results demonstrate that the studied heat wave was quite extraordinary, occurring so late in the summer with a relatively large areal extent and extremity of detected maximum air temperature. Furthermore, the Weather Extremity Index was found useful for identification of really extreme high air temperature events and facilitated inter-comparison in terms of extremity and spatial extent. However, it cannot be used for detection of all heat waves that could have severe impacts on both human activities and natural ecosystems. The work has been supported by the grant P209/11/1990 funded by the Czech Science Foundation.

    Full Text Available OBJECTIVE: To identify factors associated with negative direct sputum examination among African and Cambodian patients co-infected by Mycobacterium tuberculosis and HIV. DESIGN: Prospective multicenter study (ANRS1260 conducted in Cambodia, Senegal and Central African Republic. METHODS: Univariate and multivariate analyses (logistic regression were used to identify clinical and radiological features associated with negative direct sputum examination in HIV-infected patients with positive M. tuberculosis culture on Lowenstein-Jensen medium. RESULTS: Between September 2002 and December 2005, 175 co-infected patients were hospitalized with at least one respiratory symptom and pulmonary radiographic anomaly. Acid-fast bacillus (AFB examination was positive in sputum samples from 110 subjects (63% and negative in 65 patients (37%. Most patients were at an advanced stage of HIV disease (92% at stage III or IV of the WHO classification with a median CD4 cell count of 36/mm³. In this context, we found that sputum AFB negativity was more frequent in co-infected subjects with associated respiratory tract infections (OR = 2.8 [95%CI:1.1-7.0], dyspnea (OR = 2.5 [95%CI:1.1-5.6], and localized interstitial opacities (OR = 3.1 [95%CI:1.3-7.6], but was less frequent with CD4 ≤ 50/mm³ (OR = 0.4 [95%CI:0.2-0.90, adenopathies (OR = 0.4 [95%CI:0.2-0.93] and cavitation (OR = 0.1 [95%CI:0.03-0.6]. CONCLUSIONS: One novel finding of this study is the association between concomitant respiratory tract infection and negative sputum AFB, particularly in Cambodia. This finding suggests that repeating AFB testing in AFB-negative patients should be conducted when broad spectrum antibiotic treatment does not lead to complete recovery from respiratory symptoms. In HIV-infected patients with a CD4 cell count below 50/mm3 without an identified cause of pneumonia, systematic AFB direct sputum examination is justified because of atypical clinical

  1. Fall of the iron curtain: male life expectancy in Slovakia, in the Czech Republic and in Europe.

    Year 1989, the fall of communism, represents a dramatic watershed. Changes and reforms reflected also upon the quality of health care and the health of populations living on eastern side of the divide. Until then, Eastern Europe had free socialized medicine, albeit troubled by lack of up-to-date medications and absence of modern diagnostic equipment. Noting the admirable progress in health in some regions of the former Soviet empire during its transformation provides invaluable sociological lesson. Furthermore, focusing on health trends in two Central European countries, the Czech republic (CZ) and Slovakia (SK), brings about another quality to such evaluation. Dramatic improvement in the life expectancy (LE) is represented mainly in the decrease of cardiovascular mortality, more in the Czech Republic than in Slovakia. Favorable trend of male LE in the Czech Republic exceeded several established West European countries, while in Russia, Belarus and Ukraine the life expectancy actually deteriorated. When life expectancy in Slovakia is compared with the Czech Republic, its poorer outcome results from a higher cardiovascular mortality, as well as from liver, digestive and respiratory disorders. Root causes of this difference are possibly in a marked difference in funding of health care between SK and CZ, higher consumption of alcohol and cigarettes, as well as in a sizeable disadvantaged Roma minority in Slovakia.

    We present a preliminary analysis of aftershocks of the Mw=7.7 Republic Day (26 January) 2001 earthquake in Gujarat, India, recorded on a network of portable digital event recorders (the MAEC/ISTAR network). During the 18 day deployment, this network recorded ground motion from nearly 2000 earthquakes; almost exclusively Mveil of ignorance over the mainshock: we know of no strong-motion recordings of the mainshock, regional broad-band and seismic network data is notoriously difficult to obtain for scientific evaluation, evidence of surface rupture or deformation is fragmentary and complex or obscured by massive liquefaction, pre-existing geodetic networks are non-existent, and satellite-based radar interferometry studies have been hobbled by poor pre-earthquake images. Aftershock occurrence may provide critical evidence to determine which fault ruptured in January, 2001, and aftershock studies may provide important observational constraints on source processes and wave propagation in the region. We focus on trying to discern the mainshock fault plane, which appears to dip to the south, and whether the aftershocks are unusually deep (down to 35 km, which might help to explain the lack of obvious surface rupture). In addition to determining first-motion focal mechanisms we will examine whether stress drops of the aftershocks are, on the whole, high. We compare the seismic sources and regional propagation of Gujarati aftershocks with those of the central and eastern US.

    Full Text Available The paper is a scientific study that aims at analyzing the overhaul of the Assembly of the Republic of Macedonia in the Albanian Constitution. Assembly of the Republic of Macedonia is a representative body of citizens and the bearer of legislative power in the Republic. It is a unicameral body. Its status and its activity is regulated by the Constitution and special laws on Parliament. The Republic of Macedonia is a unitary state, with a multiethnic society. The population is made up, by two ethnic groups, Macedonians and Albanians. In the Republic of Macedonia are included the minority of Turks, Serbs, Vlachs, Romas, Bosniaks and others. As a result of many minorities and 2 ethnic groups, the structure of the Assembly of the Republic of Macedonia, which is unicameral, does not respond and fit into the actual reality of the country. Therefore, changes should be made to this regard. This reality requires also a federalization of the Republic of Macedonia by guaranteeing the freedom and the right of self-determination of both majority groups, in this case Macedonians and Albanians. It should be noted, that the Republic of Macedonia, is divided into six electoral districts, with unequal numbers of voters and in this sense, changes in the Electoral Code should be undertaken.

    At present, it is generally accepted that the average dose to the glandular tissue is the most reasonable dose descriptor in mammography with regard to the risk of breast cancer induced by ionizing radiation. It is advantageous to use the quantity mean glandular dose M.G.D. for setting of diagnostic reference levels (D.R.L.) as well, although the quantity is not directly measurable as it is the case of D.R.L. quantities for other imaging modalities. The reason is that a directly measurable quantity suitable for mammography, incident air kerma Ki, depends a lot on a beam quality. The influence of the beam quality (expressed by tube voltage, half value layer and combination of anode/filter material) is already included in calculation of mean glandular dose. To assess a radiation burden of patients due to mammography at a national level a representative dose survey is needed to carry out. Such a study provides statistically significant dose data for setting of the national diagnostic reference levels. National Radiation Protection Institute is performing the study in the Czech Republic since the year 2005.On a basis of presented data, it could be concluded, that the situation in the Czech Republic with respect to patient doses in mammography is encouraging and that the requirements of European Commission are well fulfilled. However, it is obvious, that the obtained results can not be considered as statistically significant at the moment, because the data were not collected from a representative sample of centers, which should observe a distribution of X-ray unit types, type of a mammographic center (screening/non screening ones) and also a locality of a center. The dose survey still continues to cover the whole Czech Republic with the main task to determine new national diagnostic reference levels and to find out optimized standards for carrying out the examinations with respect to patient doses and image quality.

    Thermal waters (30-61/sup 0/C) occur in springs and shallow drill-holes (max. 300 m) in several areas of the Yemen Arab Republic. Their mineral content is generally low ( < 1000-2000 ppm TDS) except for waters with high CO/sub 2/ content and those directly influenced by the evaporitic Baid formation (Tertiary) in the Western Lowlands along the Red Sea. The temperature anomalies occur in areas of Quaternary basaltic volcanism (Aden formation) and in fault zones connected with the eastern margin of the Red Sea graben. In the latter zones radiogenic heat may be contributed by Tertiary granitic intrusions.

    The paper presents data on the prevalence of dirofilariasis in the Autonomous Republic of Crimea during 5 years from 1999 to 2003. The nematode Dirofilaria repens is a causative agent of the disease. Sporadic cases of helminthiasis are annually registered in some urban and rural areas on the plain of the peninsula. The disease is absent on the foothills and Black sea coast of the southern and eastern parts of Crimea. The localization of the parasite is typical of this helminthiasis. Dirofilariasis in Crimea may be regarded as a transmissible helminthiasis with natural focal trends.

    Africa presents the most complex genetic picture of any continent, with a time depth for mitochondrial DNA (mtDNA) lineages >100,000 years. The most recent widespread demographic shift within the continent was most probably the Bantu dispersals, which archaeological and linguistic evidence suggest originated in West Africa 3,000-4,000 years ago, spreading both east and south. Here, we have carried out a thorough phylogeographic analysis of mtDNA variation in a total of 2,847 samples from throughout the continent, including 307 new sequences from southeast African Bantu speakers. The results suggest that the southeast Bantu speakers have a composite origin on the maternal line of descent, with approximately 44% of lineages deriving from West Africa, approximately 21% from either West or Central Africa, approximately 30% from East Africa, and approximately 5% from southern African Khoisan-speaking groups. The ages of the major founder types of both West and East African origin are consistent with the likely timing of Bantu dispersals, with those from the west somewhat predating those from the east. Despite this composite picture, the southeastern African Bantu groups are indistinguishable from each other with respect to their mtDNA, suggesting that they either had a common origin at the point of entry into southeastern Africa or have undergone very extensive gene flow since.

    Full Text Available This article is analyzing the trends and development in the retailing sector in Central Europe, namely in the Czech Republic, Hungary, Poland and Slovakia. These markets serve about 63 million inhabitants. The retail industry in Central Europe has changed dramatically in the last two decades, and has become a model for successful transformation of emerging markets. The retail market is highly concentrated and dominated by Western European retail chains. International retail chains are using all formats of modern distribution. This article is focusing on the development of hypermarkets, supermarkets and discount stores. Due to the international retail chains, Central European countries benefit from a dense network of modern shopping places; the intense competition of highly productive retailers contributes to the lower level of inflation rate because of the so-called Wal-Mart Effect. The constant pressure on prices influences the marketing strategies of both retailers and suppliers.

  15. An African ethic for nursing?

    Science.gov (United States)

    Haegert, S

    2000-11-01

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

    Gene therapy represents one of the most promising applications of molecular biology and genetic engineering in medicine. At present its introduction meets series of problems which are of technical, methodological and ethical nature. Although the research in the field of gene therapy in the Czech Republic is on a good level, there is little hope that its achievements will be tested in clinical trials in the near future. In the Czech Republic a law enabling the use of preparations based on the newest biotechnologies in human medicine is missing. Similarly, a production unit capable of preparing the new gene-based drugs according to the Good Manufactory Praxis is not available and the State Institute for Control of Drugs has not any working group fully qualified for their control. The paper proposes actions aimed at solving the present unfavourable situation. The fact that the interest of clinicians in gene therapy is rapidly growing, and that there are signs of increasing interest of public in its achievements, gives good prospects for the introduction of gene therapy into medical praxis in this country in the not very distant future.

    Full Text Available Remittances represent transfers of earned money of foreigners to home country and they belong to often discussed topics in the connection with migration issues. The reason is the recent increase of the number of migrants and the amount of sent remittances. Since the Czech Republic became the immigration country, remittances have gained the importance. Many foreigners come to the Czech Republic because of work or study. However, many of them send earned money back to their country of origin, to their families and relatives. The information about the foreigners is crucial for describing their behaviour (incomes, consumption expenditures and recording the transactions in national accounts and balance of payments. Permanent lack of data sources causes problems with such statistics. The aim of the paper is the description and interpretation of the issue of remittances. Procedures that are used for these estimates are briefly described with respect to the users’ needs. The description is mainly focused on the estimates of numbers and structures of foreigners, covering the length of stay, economic activity, their behaviour and estimation of sent remittances.

    The Monuments Board of the Slovak Republic within the Operational Programme Information Society from 2012, is digital documenting selected national cultural monuments of the Slovak Republic. Within this project 1,855 architectural objects in Slovakia has been digitized by internal component of the The Monuments Board SR and external suppliers. For measurement there were used the most modern surveying technologies - digital photogrammetry (DP) of land and aerial images and terrestrial laser scanning (TLS). The outputs of digitization are point cloud, highly detailed polygon models, orthoimages, gigapixel images and 2D drawing documentations. During the project, arose the need to process the huge number of images (thousands or tens of thousands) and also need a TLS connection to DP. For this reason, started Slovak commercial firm developing of new software which enable this processing and connection. The outcomes are unique spatial models of large architectural complexes (castles, monasteries, churches...) with high detail and accuracy up to 1 cm. Article is devoted to the project description and the method of digitization for the specific types of the cultural monuments.

    2010-10-01

    Full Text Available This article sets contemporary challenges to good water governance in South Africa within an important historical context. While it is correct to say that 'the world water crisis is a crisis of governance', it is problematic to assume that all states can follow a similar path toward environmentally sustainable, economically efficient and socially equitable water resources governance and management. The nexus of decision-making power varies within and beyond states, and over time. Gramsci (1971 describes this as the "constellation of social forces". Where this constellation of social forces achieves consensus, a 'historic bloc' is said to emerge giving rise to a particular state form. The South African state form has varied greatly over several centuries, giving rise to various historic blocs. The resulting body of laws and policies and the varied forms of infrastructure that were developed to harness water for multiple social practices over time constitute a complex political ecological terrain not easily amenable to oversimplified frameworks for good water governance. This article outlines the role of water in the history of South Africa’s multiple state forms. It shows that over time, water policy, law and institutions came to reflect the increasingly complex needs of multiple actors (agriculture, mining, industry, cities, the newly enfranchised represented by different state forms and their characteristic political regimes: the Dutch East India Company; the British Empire; the Union of South Africa; the apartheid and post-apartheid republics. Authoritarian, semi-authoritarian and democratic state forms have all used central-state power to serve particular interests. Through time, this constellation of social forces has widened until, today, the state has taken upon itself the task of providing "some water for all forever" (slogan of the Department of Water Affairs. As this article suggests, despite the difficult challenges presented by a

    African American women's racial identity is a major determinant for how they interpret the world around them, yet there is little research examining how specific aspects of racial identity are linked with attitudes about an event that has been highly significant for African-Americans: the election of President Barack Obama. The current study examined the relationship between African American mothers' racial identity and their perceived significance of the election of President Barack Obama as an indicator of reduced systemic and actual racism for African Americans, using a sample of 110 African American mothers residing in a Northeastern metropolitan area. Results revealed that racial centrality and assimilation positively predicted perceived significance of President Obama's election for diminishing racism. Implications and future directions are discussed.

Putting forth the relationship betweeen EU and Republic of Turkey in a clear manner, underlying factors of Republic of Turkey’s accession to the EU has been discussed in accordance with the main problem of Republic of Turkey, including overpopulation and unemployment rate. However, it is essential for EU to consider geostrategical position of Republic of Turkey bringing Europe and Asia continent together and taking place amidst Caucasus and therefore Turkish nations. After all, if Republic of Turkey’s full membership will not materialize, Republic of Turkey should seek another unions to join or form a new one. In any case, EU like Republic of Turkey is well aware of that the reasons of Republic of Turkey’s efforts in joining to the EU greatly depend on Republic of Turkey’s westernization policy.

    2004-01-01

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

    African dust pulses have important effects on the climate conditions and the marine biogeochemistry in the Canary Region. Aerosol samples have been collected at three stations on Gran Canaria Island (Taliarte at sea level, Tafira 269 m a.s.l. and Pico de la Gorra 1930 m a.s.l.) during 2000-2008. Elemental characterisation of the collected mineral aerosol and back trajectories of the air masses are used to distinguish regional African sources of dust. Dust aerosol samples from North Sahara (Morocco, North Algeria and Tunisia), West and Central Sahara (20°-30°N, 18°W-50°E) and Sahel (0°-20°N, 18°W-50°E) have shown different Ca/Ti, Al/Ti and Fe/Al ratios. Ti appears as a better tracer element of specific source of dust than Fe, probably due to a less mineral alteration during the atmospheric transport.

(Iridaceae: Iridoideae, a genus of cormous geophytes, we recognize 18 species, eight more than were included in the 1979 account of the genus by M.P. de Vos. One of these, F. ovata, based on Moraea ovata Thunb. (1800, was only discovered to be a species of Ferraria in 2001, and three more are the result of our different view of De Vos’s taxonomy. In tropical Africa, F. glutinosa is recircumscribed to include only mid- to late summer-flowering plants, usually with a single basal leaf and with purple to brown flowers often marked with yellow. A second summer-flowering species, F. candelabrum, includes taller plants with several basal leaves. Spring and early summer-flowering plants lacking foliage leaves and with yellow flowers from central Africa are referred to F. spithamea or F. welwitschii respectively.

The process of mental health care reform is explained using the framework of historical institutionalism. The explanation shows that the lack of political interest in combination with the tradition of institutional care resulted in poor availability of psychiatric care, outdated network of inpatient facilities and critical lack of community care facilities in both countries. Even though Slovak Republic adopted national programme at the governmental level, it still struggles with its implementation. The ongoing reform attempt in the Czech Republic may bring some change, thanks to a new approach towards strategic governance of the mental health care system and the mechanism of layering that the promoters of the reform use.

    Sellers, Robert M; Caldwell, Cleopatra H; Schmeelk-Cone, Karen H; Zimmerman, Marc A

    2003-09-01

    This study examines the direct and indirect relationships among racial identity, racial discrimination, perceived stress, and psychological distress in a sample of 555 African American young adults. A prospective study design was used to assess the influence of two dimensions of racial identity attitudes (i.e., centrality and public regard) on other study variables to investigate the relationship between racial identity attitudes and psychological distress. The results show some evidence of a direct relationship between racial centrality and psychological distress, as well as evidence of indirect relationships for both centrality and public regard through the impact of racial discrimination and perceived stress. In addition, racial centrality was both a risk factor for experiencing discrimination and a protective factor in buffering the negative impact of discrimination on psychological distress. Results are discussed within the context of identifying multiple pathways to psychological well-being for African American young adults within the context of racial discrimination.

    Full Text Available The African region represents the weak point of the world economy. Many African countries have still not finished the process of transforming their economy. Agriculture represents only a minor portion of their economies’ performance – however it is still a key sector of the economy (especially considering the number of people working in agriculture or people representing the agricultural population. The agricultural sector in many sub-Saharan countries is extremely sensitive and its stability affects the stability of the whole region. A very good example representing sub-Saharan Africa is the Democratic Republic of Congo (DRC. It is a country with a lot of potential, but it is classified among the poorest countries in the world. Its economy is extremely weak (despite its significant share in total GDP formation value, and underdeveloped. The share of agriculture in total GDP formation is over 42.5%. The number of people living in rural areas represents over 45 million out of a total of 75 million. The number of people working in agriculture is over 60% of the total economically active population. The economy of the country is extremely poor and fragile, mainly because of political instability. The aim of this paper is firstly to specify the position of agriculture in the DRC economy, and also to specify the production and trade commodity structure in relation to other African countries. The paper’s ambition is to identify the most perspective commodities (groups of commodities, both for production and also for trade, and to recommend such a production and trade profile which would allow the DRC the possibility of improving its competitiveness - not only in relation to other African countries, but also in relation to the global market. The production and trade commodity structures are analysed through the application of the BCG method and competitiveness analysis. In relation to these objectives, the paper provides the following conclusions

    2008-12-01

    Full Text Available Abstract Background Tropical rain forests are the most diverse terrestrial ecosystems on the planet. How this diversity evolved remains largely unexplained. In Africa, rain forests are situated in two geographically isolated regions: the West-Central Guineo-Congolian region and the coastal and montane regions of East Africa. These regions have strong floristic affinities with each other, suggesting a former connection via an Eocene pan-African rain forest. High levels of endemism observed in both regions have been hypothesized to be the result of either 1 a single break-up followed by a long isolation or 2 multiple fragmentation and reconnection since the Oligocene. To test these hypotheses the evolutionary history of endemic taxa within a rain forest restricted African lineage of the plant family Annonaceae was studied. Molecular phylogenies and divergence dates were estimated using a Bayesian relaxed uncorrelated molecular clock assumption accounting for both calibration and phylogenetic uncertainties. Results Our results provide strong evidence that East African endemic lineages of Annonaceae have multiple origins dated to significantly different times spanning the Oligocene and Miocene epochs. Moreover, these successive origins (c. 33, 16 and 8 million years – Myr coincide with known periods of aridification and geological activity in Africa that would have recurrently isolated the Guineo-Congolian rain forest from the East African one. All East African taxa were found to have diversified prior to Pleistocene times. Conclusion Molecular phylogenetic dating analyses of this large pan-African clade of Annonaceae unravels an interesting pattern of diversification for rain forest restricted trees co-occurring in West/Central and East African rain forests. Our results suggest that repeated reconnections between the West/Central and East African rain forest blocks allowed for biotic exchange while the break-ups induced speciation via vicariance

Franchising is an agreement in which franchisees receive the right to operate a business under the franchisor’s trade name in exchange for paying a fee and operating according to a specific plan (Flităr, 2003. In other words, this method of distribution is based on a contract in which the franchisor gives franchisees the right to operate a business under its trade name. In exchange, the franchisees pay a specific amount and operate the business according to a plan specified by the franchisor (Flităr, 2003.

    Large areas of African moist forests are being logged in the context of supposedly sustainable management plans. It remains however controversial whether harvesting a few trees per hectare can be maintained in the long term while preserving other forest services as well. We used a unique 24 year silvicultural experiment, encompassing 10 4 ha plots established in the Central African Republic, to assess the effect of disturbance linked to logging (two to nine trees ha⁻¹ greater than or equal to 80 cm DBH) and thinning (11-41 trees ha⁻¹ greater than or equal to 50 cm DBH) on the structure and dynamics of the forest. Before silvicultural treatments, above-ground biomass (AGB) and timber stock (i.e. the volume of commercial trees greater than or equal to 80 cm DBH) in the plots amounted 374.5 ± 58.2 Mg ha⁻¹ and 79.7 ± 45.9 m³ ha⁻¹, respectively. We found that (i) natural control forest was increasing in AGB (2.58 ± 1.73 Mg dry mass ha⁻¹ yr⁻¹) and decreasing in timber stock (-0.33 ± 1.57 m³ ha⁻¹ yr⁻¹); (ii) the AGB recovered very quickly after logging and thinning, at a rate proportional to the disturbance intensity (mean recovery after 24 years: 144%). Compared with controls, the gain almost doubled in the logged plots (4.82 ± 1.22 Mg ha⁻¹ yr⁻¹) and tripled in the logged + thinned plots (8.03 ± 1.41 Mg ha⁻¹ yr⁻¹); (iii) the timber stock recovered slowly (mean recovery after 24 years: 41%), at a rate of 0.75 ± 0.51 m³ ha⁻¹ yr⁻¹ in the logged plots, and 0.81 ± 0.74 m³ ha⁻¹ yr⁻¹ in the logged + thinned plots. Although thinning significantly increased the gain in biomass, it had no effect on the gain in timber stock. However, thinning did foster the growth and survival of small- and medium-sized timber trees and should have a positive effect over the next felling cycle.

    2014-01-01

    This paper revisits the 1962 splitting of the South African Psychological Association (SAPA), when disaffected Afrikaner psychologists broke away to form the whites-only Psychological Institute of the Republic of South Africa (PIRSA). It presents an analysis of the rhetorical justification for forming a new professional association on principles at odds with prevailing international norms, demonstrating how the episode involved more than the question of admitting black psychologists to the association. In particular, the paper argues that the SAPA-PIRSA separation resulted from an Afrikaner nationalist reading of the goals of psychological science. PIRSA, that is, insisted on promoting a discipline committed to the ethnic-national vision of the apartheid state. For its part, SAPA's racial integration was of a nominal order only, ostensibly to protect itself from international sanction. The paper concludes that, in a racist society, it is difficult to produce anything other than a racist psychology.

    Full Text Available The question ‘What constitutes African philosophy?’ was first raised with the publication of Placide Tempels’s seminal work Bantu philosophy in 1959. Tempels’s book inevitably elicited considerable critical response from African philosophers, which culminated in a wide range of publications such as Wiredu’s (1980 Philosophy and an African culture, Hountondji’s (1983 African philosophy: Myth and reality, Oruka’s (1990 Sage philosophy: Indigenous thinkers and modern debate on African philosophy, Shutte’s (1993 Philosophy for Africa, Masolo’s (1994 African philosophy in search of identity and Gyekye’s (1995 An essay of African philosophical thought: The Akan conceptual scheme. It has been over 60 years since the publication of Temples’s book and there continues to be serious debate about African philosophy. This article sought to contribute to the debate on the various conceptions of African philosophy, but with a focus on the challenges of teaching African philosophy to Philosophy of Education students at an open distance learning institution in South Africa. This article discussed the tendency amongst undergraduate Philosophy of Education students to conflate and reduce African philosophy to African cultures and traditions, and to the notion of ubuntu, and sought to understand the reasons for students’ inclination to treat African philosophy in this way. It examined students’ background knowledge of African philosophy, their critical thinking skills and whether their official study materials are selected and packaged in a manner that, in fact, adds to the challenges they face. Finally, the article explored the ways in which Philosophy of Education lecturers can adapt their pedagogy to provide students with a better understanding of African philosophy.

    2013-04-01

    The Republic of Mauritius (ROM) is a small island developing state (SIDS), part of the Mascarene Islands in West Indian Ocean, comprised by Mauritius, Rodrigues, Agalega and St. Brandon islands and several islets. ROM is exposed to many natural hazards notably cyclones, tsunamis, torrential precipitation, landslides, and droughts; and highly vulnerable sea level rise (SLR) driven by human induced climate change. The multihazard risk assessment presented in this paper is aimed at identifying the areas prone to flood, inundation and landslide hazard, and inform the development of strategy for disaster risk reduction (DRR) and climate change adaptation (CCA). Climate risk analysis - a central component of the analysis - is one of the first comprehensive climate modelling studies conducted for the country. Climate change may lift the temperature by 1-2 degree Celsius by 2060-2070, and increase sizably the intensity and frequency of extreme precipitation events. According to the IPCC Forth Assessment Report (AR4), the expected Sea Level Rise (SLR) ranges between 16 and 49 cm. Individually or in combination, the inland flood, coastal inundation and landslide hazards affect large proportion of the country. Sea level rise and the changes in precipitation regimes will amplified existing vulnerabilities and create new ones. The paper outlines an Action plan for Disaster Risk Reduction that takes into account the likely effects of climate change. The Action Plan calls on the government to establish a National Platform for Disaster Risk Reduction as recommended by the Hyogo Framework for Action (HFA) 2005-2015. It consists of nine recommendations which, if put in practice, will significantly reduce the annual damage to natural hazard and produce additional (ancillary) benefits in economic, social and environmental terms.

    No other country in the world has so few resources of fossil sources of energy and depends on imports of power as the Republic of Korea. As a consequence of economical and political processes of globalization, new challenges are developed: elevated regional and global conflicts relating to resources as well as new possibilities of cooperation by means of amore intensely international division of labour. Under this aspect, the author of the contribution under consideration reports on the energy policy of the Republic of Korea. Especially, the author reports on the following aspects: (a) Characteristics of the power structure of the Republic of Korea; (b) National energy policy and measures for energy security; (c) Practical measures of energy security; (d) Regional co-operation for energy security from the view of the Republic of Korea. The Republic of Korea has a very weak energy structure and strongly depends on foreign countries. Among the successful measures of energy security, there exist measures for energy saving in industrial areas, diversification of sources of energy and exporting countries, increase of competitiveness of the energy economy due to restructuring and privatization of national companies as well as liberalisation of the energy market. Investments in the research of energy saving technologies and renewable energy such as solar energy, hydraulic power and fuel cells are trend-setting. The development of new sources of energy and the increase of the self-fund relating to petroleum, coal and natural gas are encouraging. The Republic of Korea is not attached at the international power net. Therefore, the Republic of Korea highly is susceptible according to energy crisis. The elevated dependence from other countries will exist furthermore. The Republic of Korea should expend its activities relating to foreign affairs and the large oil producers.

    Full Text Available The demand for new healthcare services is growing rapidly. Improving accessibility of the African population to diabetes care seems to be a big challenge in most countries where the number of care centers and medical staff is reduced. Information and communication technologies (ICT have great potential to address some of these challenges faced by several countries in providing accessible, cost-effective, and high-quality health care services. This paper presents the Mobil Diab system which is a telemedical approach proposed for the management of long-term diseases. The system applies modern mobile and web technologies which overcome geographical barriers, and increase access to health care services. The idea of the system is to involve patients in the therapy process and motivate them for an active participation. For validation of the system in African context, a trial was conducted in the Democratic Republic of Congo. 40 Subjects with diabetes divided randomly into control and intervention groups were included in the test. Results show that Mobil Diab is suitable for African countries and presents a number of benefits for the population and public health care system. It improves clinical management and delivery of diabetes care services by enhancing access, quality, motivation, reassurance, efficiency, and cost-effectiveness.

    A more complete description of African elephant phylogeography would require a method that distinguishes forest and savanna elephants using DNA from low-quality samples. Although mitochondrial DNA is often the marker of choice for species identification, the unusual cytonuclear patterns in African elephants make nuclear markers more reliable. We therefore designed and utilized genetic markers for short nuclear DNA regions that contain fixed nucleotide differences between forest and savanna elephants. We used M13 forward and reverse sequences to increase the total length of PCR amplicons and to improve the quality of sequences for the target DNA. We successfully sequenced fragments of nuclear genes from dung samples of known savanna and forest elephants in the Democratic Republic of Congo, Ethiopia, and Namibia. Elephants at previously unexamined locations were found to have nucleotide character states consistent with their status as savanna or forest elephants. Using these and results from previous studies, we estimated that the short-amplicon nuclear markers could distinguish forest from savanna African elephants with more than 99% accuracy. Nuclear genotyping of museum, dung, or ivory samples will provide better-informed conservation management of Africa's elephants.

  6. The "Da Ming Hunyi Tu": Repurposing a Ming Map in Sino-African Diplomacy

    Full Text Available In 2002, an exhibition at South Africa’s parliament included a reproduction of the Da Ming Hunyi Tu (Amalgamated map of the Great Ming, citing it as the earliest world map to depict the entire African continent. As part of its broader efforts to shape a narrative of long-standing and peaceful international relations with Africa, the People’s Republic of China formally presented a replica of this map as a gift to the South African government in conjunction with the exhibition. In official statements and popular media coverage alike, the map was described as evidence of a distinctly Chinese approach to global relations, based on benevolence and mutual respect. In particular, the map was ahistorically intertwined with the legacy of Zheng He’s diplomatic expeditions, which reached the East African coast in the early 1400s. To the cartographic historian, however, the depiction of Africa in the Da Ming Hunyi Tu is clearly derived from non-Chinese sources that predate Zheng He’s expeditions. This article examines the ways in which the map has been divorced from its original context to suit modern needs, exemplifying the deployment of cartography to deflect anxieties about the nature of Chinese economic influence in South Africa.

    African rice (Oryza glaberrima) and African cultivation practices are said to have influenced emerging colonial plantation economies in the Americas(1,2). However, the level of impact of African rice practices is difficult to establish because of limited written or botanical records(2,3). Recent findings of O. glaberrima in rice fields of Suriname Maroons bear evidence of the high level of knowledge about rice among African slaves and their descendants, who consecrate it in ancestor rituals(4,5). Here we establish the strong similarity, and hence likely origin, of the first extant New World landrace of O. glaberrima to landraces from the Upper Guinean forests in West Africa. We collected African rice from a Maroon market in Paramaribo, Suriname, propagated it, sequenced its genome(6) and compared it with genomes of 109 accessions representing O. glaberrima diversity across West Africa. By analysing 1,649,769 single nucleotide polymorphisms (SNPs) in clustering analyses, the Suriname sample appears sister to an Ivory Coast landrace, and shows no evidence of introgression from Asian rice. Whereas the Dutch took most slaves from Ghana, Benin and Central Africa(7), the diaries of slave ship captains record the purchase of food for provisions when sailing along the West African Coast(8), offering one possible explanation for the patterns of genetic similarity. This study demonstrates the utility of genomics in understanding the largely unwritten histories of crop cultures of diaspora communities.

    Full Text Available This faulting tectonics analysis concerns the southernmost segment of the Dahomeyide Orogen and the West-African craton eastern margin in southeast Ghana. The analysis of strike-slip faults in the frontal units of the Dahomeyide Belt indicates that four distinct compressive events (NE-SW, ENE-WSW to E-W, ESE-WNW to SE-NW and SE-NW to SSE-NNW originated the juxtaposition of the Pan-African Mobile Zone and the West-African craton. These paleostress systems define a clockwise rotation of the compressional axis during the structuring of the Dahomeyide Orogen (650–550 Ma. The SE-NW and SSE-NNW to N-S compressional axes in the cratonic domain and its cover (Volta Basin suggest that the reactivation of the eastern edge of the West African craton is coeval with the last stages of the Pan-African tectogenesis in southeast Ghana. An extensional episode expressed as late normal faulting is also recorded in this study. This E-W to SE-NW extension, which is particular to the southernmost part of the Dahomeyide Belt, appears to be post-Pan-African. This extension probably contributed to the formation of a major Jurassic rifting zone that originated the Central Atlantic and the Benue Trough.

    Full Text Available This paper examines the validity of purchasing power parity (PPP hypothesis in the Republic of Croatia. The main aim is to test whether the PPP Theory holds in the case of the Republic of Croatia and whether the PPP Theory is an appropriate method on which monetary policy makers can rely in determining the size of the market exchange rate deviations from its long-run value. The PPP Theory in the Republic of Croatia has been tested using methods of cointegration analysis. Two cointegration tests have been applied: Engle-Granger test and ADL test. The existence of the long-run relationship between the price level in the EMU (expressed in Croatian Kuna and the price level in the Republic of Croatia has been tested using monthly observations of average nominal Croatian Kuna exchange rate against Euro, Consumer Prices Index in the Republic of Croatia (2005=100 and the Harmonised Index of Consumer Prices for the European Monetary Union (2005=100 in the period from January 2000. to December 2012. Based on the Engle-Granger test, it can't be concluded if there is a long-run relationship between the two price levels. The non-existence of the long-run relationship between two price levels has also been confirmed by the ADL cointegration test. Thus, on the basis of the cointegration tests it can be concluded that the PPP hypothesis in the Republic of Croatia has not been confirmed.

Nationwide suicide rate was stratified by four year age-groups, sex, urban/rural areas, and regions (East, Central, and West. Annual economic indexes including gross domestic product (GDP per capita and rural and urban income per capita were all adjusted for inflation. Variation coefficient of market index (VCMI was also included as an economic index to measure the fluctuation of the stock market. Negative binomial regression was performed to examine the time trend of region-level suicide rates and effects of sex, age, urban/rural area, region, and economic index on the suicide rates.Results: Suicide rates of each age-group, sex, urban/rural area, and region were generally decreased from 2004 to 2013, while annual GDP per capita and rural and urban income per capita were generally increased by year. VCMI fluctuated largely, which peaked around 2009 and decreased after that time. Negative binomial regression showed that the decreased suicide rate in East and Central rural areas was the main cause of the

    Human African trypanosomiasis (HAT) or sleeping sickness is a parasitic disease, acquired by the bite of an infected tsetse fly. In non-endemic countries HAT is rare, and therefore the diagnosis may be delayed leading to potentially fatal consequences. In this article the clinical presentation, diagnosis and treatment of the two forms of HAT are outlined. Rhodesiense HAT is an acute illness that presents in tourists who have recently visited game parks in Eastern or Southern Africa, whereas Gambiense HAT has a more chronic clinical course, in individuals from West or Central Africa.

  6. Central Africa Energy: Utilizing NASA Earth Observations to Explore Flared Gas as an Energy Source Alternative to Biomass in Central Africa

    Much of Central Africa's economy is centered on oil production. Oil deposits lie below vast amounts of compressed natural gas. The latter is often flared off during oil extraction due to a lack of the infrastructure needed to utilize it for productive energy generation. Though gas flaring is discouraged by many due to its contributions to greenhouse emissions, it represents a waste process and is rarely tracked or recorded in this region. In contrast to this energy waste, roughly 80% of Africa's population lacks access to electricity and in turn uses biomass such as wood for heat and light. In addition to the dangers incurred from collecting and using biomass, the practice commonly leads to ecological change through the acquisition of wood from forests surrounding urban areas. The objective of this project was to gain insight on domestic energy usage in Central Africa, specifically Angola, Gabon, and the Republic of Congo. This was done through an analysis of deforestation, an estimation of gas flared, and a suitability study for the infrastructure needed to realize the natural gas resources. The energy from potential natural gas production was compared to the energy equivalent of the biomass being harvested. A site suitability study for natural gas pipeline routes from flare sites to populous locations was conducted to assess the feasibility of utilizing natural gas for domestic energy needs. Analyses and results were shared with project partners, as well as this project's open source approach to assessing the energy sector. Ultimately, Africa's growth demands energy for its people, and natural gas is already being produced by the flourishing petroleum industry in numerous African countries. By utilizing this gas, Africa could reduce flaring, recuperate the financial and environmental loss that flaring accounts for, and unlock a plentiful domestic energy source for its people. II. Introduction Background Africa is home to numerous burgeoning economies; a

    We analyze droughts in the Czech Republic from 1881-2006 based on the Palmer drought severity index (PDSI) and the Z-index using averaged national temperature and precipitation series for the calculations. The standardized precipitation index (SPI), PDSI and Z-index series show an increasing tendency towards longer and more intensive dry episodes in which, for example, droughts that occurred in the mid-1930s, late 1940s-early 1950s, late 1980s-early 1990s and early 2000s were the most severe. Cycles at periods of 3.4-3.5, 4.2-4.3, 5.0-5.1 and 15.4 years exceeded 95% confidence levels in application of maximum entropy spectral analysis. These are expressed at different intensities throughout the period studied. The occurrence of extremely dry and severely dry months is associated with a higher frequency of anticyclonic situations according to the classification employed by the Czech Hydrometeorological Institute. Principal component analysis documents the importance of the ridge from the Siberian High over Central Europe when extreme and severe droughts in months of the winter half-year are considered in terms of sea-level pressure. In the summer half-year, the ridge of the Azores High over Central Europe is the most important. Drought episodes have a profound effect on national and regional agricultural production, with yields being consistently lower than in normal years, as is documented through the example of spring barley, winter wheat, forage crops on arable land, and hay from meadows. Seasons with pronounced drought during the April-June period (e.g., 1947 and 2000) show the most significant yield decreases. Forests appear to be very vulnerable to long-term drought episodes, as it was the case during the dry years of 1992-1994. This study clearly confirms the statistically significant tendency to more intensive dry episodes in the region, driven by temperature increase and precipitation decrease, which has already been suggested in other studies.

    Full Text Available Education has, since the beginning of time, been regarded as the formal process by which society conveys its accumulated knowledge, skills, customs and values from one generation to another. Today, education is a human right, and the right to education and specifically the right to (a basic education is acknowledged and emphasised worldwide. In South Africa the right to a basic education is entrenched in the Constitution of the Republic of South Africa, 1996 and is regarded as one of the most crucial constitutional rights, particularly because it promotes economic and social well-being. However, the South African school system is crippled by a myriad of unfavourable challenges, situations and circumstances which will be discussed throughout the article. Many of these challenges, situations and circumstances are frustrating and solutions have been sought diligently – many with success and many without success. The focus in this article falls on the questions of whether the current South African school system sufficiently realises the constitutional rights of learners and whether an alternative school system could lead to the increased fulfilment and realisation of South African children's rights (with a specific focus on the rights to a basic education, equality and dignity. The article therefore deals with the "acceptability" of the South African school system. A comparative analysis with Germany will be done and the German school system will be used as a valuable framework in order to propose an alternative school system for South Africa.

    2003-08-01

    The human African trypanosomiasis is essentially a rural disease. The notification of cases in urban area has always been incidental; either a diagnosis made in town revealed a disease contracted in rural environment or it meant the preservation of a complete epidemiological cycle in a remaining urban micro-focus. In Kinshasa, in Democratic Republic of Congo, about forty cases have been notified each year. All of them came from the nearby foci of Bandundu, Lower Congo and Kasaï. In 1996 the number of cases reached suddenly 254 and today the average annual number comes up to 500 in spite of all the efforts undertaken to fight the disease. A study of cases in 1998 and 1999 shows that patients are essentially distributed in suburbs and that the most affected by the disease are the 15-49 year old ones whose job is related with agricultural or fishing activities. Two phenomena seem to explain this sudden increase: the massive inflow of refugees in outskirts of town coming from provinces where trypanosomiasis is endemic and a major economic crisis throwing out urban population in suburbs living on a subsistence micro-agriculture. These concomitant factors have contributed to the setting up of a trypanosomiasis belt around the capital. Today a strategy has to be reconsidered in order to fight against the disease in the capital itself and to make the medical staff aware of the diagnosis of a disease still unknown in their sanitary district.

    Large-scale importation of bushmeat from West and Central Africa into Europe was reported in 2010. We sampled 18 illegal African bushmeat consignments seized at Charles de Gaulle airport, Paris, France and tested for the presence of bacteria. Additionally, five smuggled smoked fish were analysed for polycyclic aromatic hydrocarbons, which are known carcinogens. All bushmeat samples had viable counts of aerobic bacteria above levels considered safe for human consumption. We also identified zoonotic bacterial pathogens in bushmeat and unsafe levels of carcinogens in fish. The illegal importation of meat is a potential risk for the introduction of pathogens.

    Full Text Available This paper examines how Turkey's domestic resources, which are Turkey's historical, cultural and political relations with the Turkic states and Turkey's economic interests in the region, affect Turkey's foreign relations with Azerbaijan, Kazakhstan, Kyrgyzstan, Turkmenistan and Uzbekistan. Findings show that the Turkic Republics' interest in Turkish development model gradually declined starting from the 1994s. The hypothesis that the stronger socio-cultural ties between Turkey and the Turkic states are the closer the foreign relations are between Turkey and the Turkic states is applicable to all five republics. In the field of business the study finds that Turkish economy follows a similar pattern in its relations with the Azerbaijani and the Central Asian market. Common policy goals of Turkey and the five states led Turkey to establish close foreign relations with these five regional countries. The hypothesis that the more Turkey has business interests in the Caspian Sea Region the more Turkey will have closer foreign relations with Turkic states is mostly apparent in the case of Azerbaijan. In the area of energy politics Turkey has its strongest link with Azerbaijan. Besides being strong economic partners Turkey is Azerbaijan's biggest supporter in the region against Armenia.

    Full Text Available In 2014, the Czech automotive industry had a record-breaking year with 1 278 000 motor vehicles manufactured. This was a result of the investment of three major carmakers, who entered into the Czech Republic, because they believed in the industrial capacity of the country and its strategic location in Central Europe. The goal of this article is to analyze the different entry strategies into the Czech market and to compare the results of different strategic approaches for both foreign private investors and the recipient country. The main research method used in this article is a case study. In our case studies, we will analyze the cases of the Volkswagen group and its acquisition of the manufacturer Škoda, the greenfield investment of Hyundai, and the strategic alliance of the French car producer PSA with Japanese Toyota who had founded the TPCA joint venture in the Czech Republic. All three case studies show examples of good practices and prove that foreign direct investment (FDI has the potential to generate employment, raise productivity, transfer skills and technology, enhance exports and contribute to the long-term economic development of the country.

    2008-06-01

    Full Text Available Applying the principles of sustainable development and ensuring sustainable economic development are of primordial actuality for the Republic of Moldova. Promoting sustainable development presupposes correlating economic growth with improving the quality of life and health, education, social development and environmental protection. The issue of sustainable development as a complex phenomenon is approached under the conditions of the influence exerted by some constraints and restrictions, of the existence of some serious economic, social and technological gaps in regional and European context. The analysis of the external commercial flows of goods highlights the predominance in exports of products from the traditional economic sectors. Improving competitiveness of export is regarded as the decisive factor of sustainable economic growth. For the chapter regarding the reform of the investment climate, modest successes are recorded which did not give the necessary impetus to massive foreign capital entries under the form of foreign direct investments as compared with other Central and Eastern European countries. The low attractiveness for foreign direct investments is attenuated by the small size of the local market and the low purchasing power of the population. Ensuring economic sustainable development is approached within the context of creating the necessary premises and valuing the opportunities provided by the protects for European integration of the Republic of Moldova.

    2012-06-01

    Full Text Available Poppy seed (Papaver somniferum l. is an important oilseed, whose cultivation has a long tradition in the Czech Republic. Poppy seed grown in the Czech Republic has good quality and, therefore, is preferred to poppy seeds in other parts of the world. The objective of this paper is to characterize the current position of the Czech poppy seed production and foreign trade in the world. Czech Republic is the main world producer of poppy seed and price maker of the European and world prices. With regards to trade, the Czech Republic is also the main producer and seller both in Europe and in the world. The poppy seed crop grown in the Czech Republic is mainly produced for exports, because the domestic consumption consists of only between four and five thousand tons. Major export markets of Czech poppy seed are European countries with a population of Slavic origin or those influenced by Slavic cuisine. Another important markets are overseas countries, that were settled by Slavic immigrants. The paper stresses out the position of the Czech Republic as a major player in the world market with poppy seed. The paper provides analysis of the market position of the Czech production and Czech foreign trade participation. Development of production and trade, as well as some other factors affecting the poppy seed economy, are analyzed such as prices, hectarage, yields, volume of production and volume of trade. This paper is part of a research project carried out by the authors within the grant no. 6046070906, funded by the Ministry of Education, Youth and Sports of the Czech Republic.

    2014-12-01

    Full Text Available The last three decades of significant political, economic and social transformations in the People’s Republic of China have had a profound impact on the Chinese society. The article addresses selected topics of Chinese migration that give a more nuanced understanding of migration processes and their contextualization within the contemporary Chinese society: the internal migration, emigration from China and international immigration to China. Migration from rural area towards urban eastern coast is one of the largest spatial movements in the human history, as well as a key component of the economic rise and subsequent social change. Emigration from China has, despite its relatively small volume, profoundly transformed local places of origin, a process that is not independent from the current international geopolitical situation. Immigration of international migrants to China is a relatively new phenomenon that puts the country on the map of migration destination countries for the first time in sixty years. The author concludes that the prevalent research perspectives on Chinese migration offer only a limited insight and suggests some possible alternative ways of analyzing this phenomenon.

    Full Text Available Entrepreneurship is one of the possible solutions to the pan-European problem of youth unemployment. The objective of the research was to identify differences between male and female entrepreneurs in their opinions of entrepreneurship of young people. We wanted to find out whether male and female entrepreneurs would recommend young people to do business and what factors in their opinion can influence the fact whether young people start business. To collect data, we used a questionnaire sent to entrepreneurs from the whole Czech Republic. The most important barrier identified by entrepreneurs was frequently amended legislation, complexity of administration, poor enforceability of law and a lack of funds. The most important incentives of young people according to entrepreneurs is particularly the vision of opportunities in business. Another important incentive is becoming more independent. Statistically significant differences in the responses of men and women were found in the barrier related to the personal knowledge of an unsuccessful entrepreneur and in the incentive of the necessity to start business due to the lack of a job. Sufficient funding and possessing business premises were factors in which statistically significant differences in the responses of men and women were found, too. This research emphasises factors which women and men can find important in making a decision on starting business or being employed.

  3. [Darwin in the Republic of Letters].

    2013-01-01

    For those accustomed to thinking that the modern cultural dimension arose under the banner of a clash between the so-called "two cultures," the figure of Darwin the "humanist" could reserve numerous surprises. It was above all the well-known paleontologist S.J. Gould who pointed them out. He went so far as to track down, in the Italian cultural roots from Saint Francis to Galileo, an element of continuity between his own Darwinism and our literary tradition that passes through the writing of the masterpieces of the nineteenth-century natural sciences. On the basis of a similar, and also audacious, rereading of the cultural history, the essay proposes to indicate some possible developments of the new dialogue undertaken, beginning with the insertion of the scientist Darwin in the European horizon of the Republic of Letters. There are then indicated some historical-cultural categories that would merit reconsideration: the new figure of intellectual of the twenty-first century, the idea of a science immersed in the historical contingency and in the concrete pleasure of the subject that knows, the role of "sweetness" and of "wonder" also in the most rigorous study, and lastly the need of an in-depth knowledge of the Darwinian writing, not as a curiosity for the educational trend of the era of positivism, but as an indispensable epistemological requisite for a correct understanding of its science.

    Human prion diseases are a group of very rare diseases with a unique pathogenesis and, due to an inauspicious prognosis and unavailability of therapy, with fatal consequences. The etiopathogenetic background is the presence of pathologically misfolded prion protein, highly resistant to denaturation, the aggregation and presence of which in the brain tissue causes irreversible neuronal damage. The most frequent prion disease in humans is Creutzfeldt-Jakob disease (CJD) which occurs in sporadic, hereditary/familial, or acquired/infectious/iatrogenic forms. A new form of CJD, variant CJD, is considered to be linked to dietary exposure to beef products from cattle infected with bovine spongiform encephalopathy (BSE) and to infection via blood transfusion. The clinical picture of these diseases is characterized by a rapidly progressing dementia, cerebellar and extrapyramidal symptoms, and rather specific MRI, EEG, and CSF findings. Clinically, the diagnosis is described as possible or probable prion disease and needs to be confirmed by neuropathological or immunological investigation of the brain tissue. Epidemiological data from the Czech Republic spanning the last decade are presented.

    AbstractYemen located on the southwest corner of the Arabian Peninsula. It is known that Yemen is important to world energy markets because of its oil and natural gas resources as well as its strategic location at the Bab el - Mandab strait linking the Red Sea and the Gulf of Aden. Due to the Ministry of Oil and Mineral Resources (MOMR, 1998E) the Yemeni Oil Production was estimated to be 385 000 barrels per day (bbl/d), Oil Consumption was 69 000 bbl/d and Net Oil Exports was 316 000 barrels per day (bbl/d). On 1999 the Yemeni Proven Oil Reserves was estimated to be 4 billion barrels and the Natural Gas Reserves was estimated to be 16.9 trillion cubic feet (Tcf) (Ministry of Oil and Mineral Resources, 1999). At this time, many researchers, scientific expeditions and foreign companies are interested in Yemen. This paper discussed the petroleum overview of the Republic of Yemen. In my opinion, Yemen is not just going to attract all with its oil and gas discoveries in the near future, but also with its new geological data and information.

    The University Corporation for Atmospheric Research (UCAR) Africa Initiative (AI) is a coordinated effort aimed at building sustainable partnerships between UCAR and African institutions in order to pursue research and applications for the benefit of the African people. The initiative is based on four fundamental operating principles, concisely summarized by the overall philosophy of enabling African solutions to African needs. The four principles are: • Collaborate with African institutions • Focus on institutional capacity building and research support • Explore science research themes critical to Africa and important for the world • Leverage the research infrastructure in UCAR to add value These principles are realized in a set of pilot activities, chosen for their high probability of short-term results and ability to set the stage for longer-term collaboration. The three pilot activities are listed below. 1. A modest radar network and data-distribution system in Mali and Burkina Faso, including a data-sharing MOU between the Mail and Burkina Faso Weather Services. 2. A partnership among UCAR, the Ghana Meteorological Agency, and the Ghana university community to develop an operational Weather Research and Forecasting (WRF) model for West Africa. The output is used by researchers and operational forecasters in Africa. Model output is also part of a demonstration project that aims to allow humanitarian agencies to share geo-referenced information in Africa via a web portal. 3. A workshop in Ouagadougou, Burkina Faso from April 2-6, 2007, with the theme Improving Lives by Understanding Weather. The workshop, co-organized with Programme SAAGA and the Commité Permanent Inter-Etats de Lutte Contre la Sécheresse dans le Sahel (CILSS), included over 80 participants from 18 countries, and produced a set of recommendations for continued collaboration. Our presentation will provide an update of these pilot activities and point to future directions. Recognizing

    2015-01-01

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

  10. Historic and early life origins of hypertension in Africans.

    Science.gov (United States)

    Forrester, Terrence

    2004-01-01

    Cardiovascular disease (CVD) causes 12.4 million deaths annually, most (9.6 million) occurring in developing countries. Hypertension, the most common CVD, arises within the context of obesity, but the underlying mechanisms remain obscure. Obesity and salt intake are two important risk factors for hypertension and are the focus of this paper. Traditional African populations show a low prevalence of hypertension, but hypertension is more common in migrant African populations in the West than in other ethnic groups. One explanation is genetic, but no causative gene has been confidently identified. Nongenetic susceptibilities such as fetal programming are an alternative explanation. Hypothetically, fetal programming induced by transient stimuli permanently alters fetal structure and function at the cellular, organ and whole-body levels. Birth weight is inversely related to blood pressure and hypertension risk, suggesting that susceptibility to hypertension risk factors such as obesity and salt sensitivity are themselves programmed. In support of this hypothesis, obesity (especially central obesity) is also inversely related to size at birth. Likewise, salt sensitivity might derive from undernutrition in utero, reducing the nephron number and resetting the pressure-natriuresis curve rightward. However, no robust human data or evidence of enhanced salt sensitivity among African-origin populations exist. In the United States, blacks have a greater prevalence of low birth weight than whites, suggesting that the higher prevalence of hypertension among blacks is related to fetal programming. Nevertheless, we need to be scrupulous in ascribing risk to the myriad other confounders of this relationship, including environmental and behavioral correlates of ethnicity, before concluding that excess risk of hypertension in Africans is programmed in utero.

    Purpose While management research in African context is all but invisible in management literature, the notion of "African management" emerges through a piecemeal corpus of literature that has arisen in response to the exclusion and marginalisation of Africa in the broad field of management literature. The idea underlying this reasoning is that the Western management model prevailing so far in Africa is inadequate because of cultural considerations. However, what is meant by “African manag...

    Dental modifications in the Caribbean are considered to be an African practice introduced to the Caribbean archipelago by the influx of enslaved Africans during colonial times. Skeletal remains which exhibited dental modifications are by default considered to be Africans, African descendants, or post-contact indigenous people influenced by an African practice. Individual E-105 from the site of Canímar Abajo (Cuba), with a direct 14C AMS date of 990-800 cal BC, provides the first unequivocal evidence of dental modifications in the Antilles prior to contact with Europeans in AD 1492. Central incisors showing evidence of significant crown reduction (loss of crown volume regardless of its etiology) were examined macroscopically and with a scanning electron microscope (SEM) to determine if the observed alterations were due to deliberate modification or other (unintentional) factors considered: postmortem breakage, violent accidental breakage, non-dietary use of teeth, and wear caused by habitual or repeated actions. The pattern of crown reduction is consistent with deliberate dental modification of the type commonly encountered among African and African descendent communities in post-contact Caribbean archaeological assemblages. Six additional individuals show similar pattern of crown reduction of maxillary incisors with no analogous wear in corresponding mandibular dentition.

    Directory of Open Access Journals (Sweden)

    Novotny Damir

    2006-01-01

    Full Text Available Financial sector in the Republic of Croatia had a strong growth between 1995 2005.g. Liberalization of financial sector in 1999 led to an increase in bank foreign debt, which resulted in a strong increase in foreign currency reserves and appreciation of the national currency. The growth of the financial sector and credit expansion have been allocated in favour of private and public consumption, but not in industry investments. GDP growth didn't have the same momentum as financial aggregates. Economic growth, after a contraction in 1999 was within the average of global economic growth. Relying on neoclassical growth model, government and central bank didn't put in place the needed set of pro-active policies. Factor allocation was solely through private bank channels financing private consumption. If the sustainable economic growth and new employment are to be major macroeconomic goals, a new macroeconomic paradigm as combination of neclassical and neokeynesians approach will be needed.
