The ongoing war in the Democratic Republic of Congo (DRC) has caused sustained trauma on a number of levels and stressors that could easily have debilitating consequences on the mental health of Congolese citizens. The literature further reveals that immigration brings with it a host of additional stressors. The stress related to immigration, an appreciation of diverse cultural understandings of mental health, the burdens and costs of adequate mental health policy and provisioning within developing countries, are concepts that are not well understood nor fully documented. The present study explored the cultural understanding and help-seeking behaviours of Congolese immigrants in South Africa. The purpose of the study was to understand the ways in which Congolese cope with stressors related to immigration. Using SocialIdentity Theory as a partial conceptual framework, the role of acculturation processes in their understanding and help-seeking behaviours regarding mental health challenges, were examined. A platform for participants to suggest suitable ways of responding to improving the management of mental challenges in their community was provided. A qualitative approach, based on Participatory Action Research (PAR) and content analysis to explore the emerging narratives, was used with a Gauteng-based sample to gather the accounts of the lived experiences of Congolese immigrants. A snowball sampling technique enabled twenty-seven respondents to participate in one paired conversation and five focus groups. The emerging findings are critically discussed aligned to the six categories of inquiry structured by the interview schedule, namely, coping strategies since immigration, the understanding of mental health challenges, the possible impact of being immersed in the South African culture, perceptions of mental challenges and persons affected within the Congolese community, the preferred help-seeking behaviours regarding mental health challenges and, finally, their recommendations for improving the management of mental health challenges. The layered meta-analysis of the data consisted of interrogating the thematic categories, then conducting an analytical review aligned to both the pertinent research aim and objectives, as well as related theoretical positions and research findings. v | P a g e The key research question underpinning this study was formulated as follows: “Will immigrating from the DRC to South Africa change the understanding and help-seeking behaviours of Congolese?” The study drew on the processes of acculturation from Social Identity Theory to examine these processes. Participants reported experiencing the effects of acculturation but in different ways. Patterns of assimilation, separation and integration were found. The study therefore served to contribute to our understanding of the effects of acculturation with regard to the cultural understanding and help-seeking behaviours of Congolese immigrants in South Africa regarding mental health. Most significantly, the assumption of high levels of trauma and stress within this vulnerable community were unfounded. Rich and complex survival strategies have emerged requiring refinement of our knowledge about migrant communities. The strengths and relative weaknesses of the study are shared as well as a set of recommendations for future research in this domain. / Psychology / M. Sc.(Psychology)

Armed conflict and violence against civilians in the Democratic Republic of the Congo has persisted for years starting in the 1990s. The Eastern, Western and North-Eastern parts of the country have seen the presence of a multiplicity of armed groups that have caused an escalation of the humanitarian crisis. The United Nations, in the interest of civilian protection, peacekeeping and security sector reform in the Democratic Republic of the Congo declared a mission under The United Nations Organisational Mission in the Democratic Republic of the Congo (MONUC). In spite of this mission, civilians continued in the Congo to suffer attacks and to endure human rights abuses by the armed militants that are fighting government and the government forces in shape of the Armed Forces of the Democratic Republic of the Congo (FARDC). This study examines the problematique of the mandate of MONUC in the Democratic Republic of the Congo in light of the challenges that have made its success debatable. The success of MONUC has become debatable in light of the fact that in spite of its presence and implementation in the DRC, between 2007 and 2010, conflict and the violence against civilians escalated to unprecedented levels. This study examines the causalities of the failure and observes its effect while making propositions towards amelioration of the challenges and the failure of the United Nations Mission in the Democratic Republic of the Congo. / Political Sciences / M.A. (International Politics)

The focus in this dissertation is on the rise of secessionism and its curtailment in the Democratic Republic of Congo (DRC). Theories pertaining to centre-periphery relations, as well as right-sizing the state, are used for this purpose. Factors such as the DRC’s vast territory and colonial policies affected the centre-periphery relations after independence. The weak ties between the centre and the peripheries were important factors in the attempts at secession that followed independence. In addition, the political and administrative centre (Kinshasa) was too weak to keep the restive peripheries in check. International military intervention, thus, played an important role in defeating attempts at secession. The strategies of President Mobutu in strengthening the centre, as well as the lack of secessionism in the DRC after the collapse of the centre towards the end of Mobutu’s presidency, receive attention. / Political Sciences / M.A. (Politics)

The one of the most important Eras of the Earth history, i.e. Neoproterozoic (1000-542 Ma),<p>was an enigmatic period characterized by the development of the first stable long-lived ~1.1-<p>0.9 Ga Rodinia and 550-500 Ma Gondwana supercontinents, global-scale orogenic belts,<p>extreme climatic changes (cf. Snowball Earth Hypothesis), the development of microbial<p>organisms facilitating the oxidizing atmosphere and explosion of eukaryotic forms toward the<p>first animals in the terminal Proterozoic. This thesis presents a multidisciplinary study of two<p>Neoproterozoic basins, i.e. Bas-Congo and Sankuru-Mbuji-Mayi-Lomami-Lovoy, in and around the Congo Craton including sedimentology, geochemistry, diagenesis, chemostratigraphy and radiometric dating of carbonate deposits themselves.<p><p>The Mbuji-Mayi Supergroup sequence deposited in a SE-NW trending 1500 m-thick siliciclastic-carbonate intracratonic failed-rift basin, extends from the northern Katanga Province towards the centre of the Congo River Basin. The 1000 m-thick carbonate succession is related to the evolution of a marine ramp submitted to evaporation, with ‘deep’ shaly basinal and low-energy carbonate outer-ramp environments, marine biohermal midramp (MF6) and ‘very shallow’ restricted tide-dominated lagoonal inner-ramp (MF7-MF9) settings overlain by lacustrine (MF10) and sabkha (MF11) environments, periodically<p>submitted to a river water source with a possible freshwater-influence. The sequence stratigraphy shows that the sedimentation is cyclic in the inner ramp with plurimetric ‘thin’ peritidal cycles (± 4 m on average) recording a relative sea level of a maximum of 4 m, with fluctuations in the range of 1-4 m. The outer/mid ramp subtidal facies are also cyclic with ‘thick’ subtidal cycles characterized by an average thickness of ± 17 m, with a probable sealevel<p>fluctuations around 10 to 20 m. The geochemistry approach, including isotopic and major/trace and REE+Y data, allows to infer the nature of the dolomitization processes operating in each carbonate subgroup, i.e dolomitization may be attributed to evaporative reflux of groundwater or to mixing zones of freshwater lenses. The latest alteration processes occured during the uplift of the SMLL Basin. New ages, including LA-ICP-MS U-Pb laser ablation data on detrital zircon grains retrieved in the lower arenaceous-pelitic sequence (BI group), combined with carbon and strontium isotopic analyses, yielded a new depositional time frame of the Mbuji-Mayi Supergroup between 1176 and 800 Ma reinforcing the formerly suggested correlation with the Roan Group in the Katanga Province.<p><p>In the Democratic Republic of Congo, the Sturtian-Marinoan interglacial period was previously related to pre-glacial carbonate-dominated shallow marine sedimentation of the Haut-Shiloango Subgroup with stromatolitic reefs at the transition between greenhouse (warm) and icehouse (cold) climate periods, commonly marked by worldwide glacigenic diamictites and cap carbonates. This thesis highlights that these deposists record as a deepening-upward evolution from storm-influenced facies in mid- and outer-ramps to deepwater environments, with emplacement of mass flow deposits in toe-of-slope settings controlled by synsedimentary faults. In absence of diagnostic glacial features, the marinoan Upper Diamictite Formation is interpreted as a continuous sediment gravity flow deposition along carbonate platform-margin slopes, which occurred along tectonically active continental margins locally influenced by altitude glaciers, developed after a rift–drift transition. The maximum depth of the deepening-upward facies is observed in the C2a member. The<p>shallowing-upward facies exibit a return of distally calcareous tempestites and semi-restricted to restricted peritidal carbonates associated with shallow lagoonal subtidal and intertidal zones submitted to detrital fluxes in the upper C2b to C3b members.<p>The geochemistry highlights (i) the existence of a δ13C-depth gradient of shallow-water and deep-water carbonates; (ii) the carbonate systems were deposited in oxic to suboxic conditions; and (iii) all samples have uniform flat non-marine shale-normalized REE+Y distributions reflecting<p>continental detrital inputs in nearshore environments, or that the nearshore sediments were<p>reworked from ’shallow’ inner to mid-ramp settings in deep-water slope and outer-ramp<p>environments, during the rift-drift transition in the basin. The pre-, syn- and post-glacial<p>carbonate systems could record a distally short-lived regional synrift freshwater-influenced<p>submarine fan derived from nearshore sediments, including gravity flow structures, which are<p>attributed to regional tectonic processes due to a sudden deepening of the basin caused by<p>differential tilting and uplifting of blocks, related to the 750-670 Ma oceanic spreading of the<p>central-southern Macaúbas Basin.<p><p>Combining sedimentology, isotopes and trace elemental geochemistry, the thesis highlights<p>that the δ13C variations in the Neoproterozoic carbonates are complex to interpret, and can be<p>related to: (i) the existence of a δ13C-depth gradient; (ii) the exchange between isotopically<p>light carbon in meteoric waters and carbonate during lithification and early diagenesis; and<p>(iii) isotopic perturbations due to regional metamorphism. Considering the possible englaciation of the Earth (Snowball Earth hypothesis), the Mbuji-Mayi Supergroup and West<p>Congolian Group seem reflected the intimate relationship between glaciations and tectonic<p>activity during the break-up of the Rodinia supercontinent, followed by the rift–drift<p>transition, and finally the pre-orogenic period on the passive continental margin. / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

Pericopsis elata is an African forestry species commercialized under the vernacular names afrormosia or assamela. It is one of the principal species commonly exploited for timber in the Democratic Republic of Congo (DRC) and in a lesser extent in Cameroon and Congo. In view of its sustainable resource exploitation, the species is in centre of numerous polemics notably in the European Union. It is one of the rare commercialized species that produce wood, since 1992, as listed in the CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) annex II specifying that “the exploitation of afrormosia necessitate the deliverance and a prior presentation of exploitation permit”. The most important reserves of afrormosia are found in DRC. This doctoral thesis presents the ecology of this particular tree and its behaviour regarding forestry exploitation. It allows to inform the international organisms such as CITES as well as the national policy-makers on the vulnerability of afrormosia and to propose appropriate measures that can avoid future unsustainable/unregulated exploitation activities/Pericopsis elata est une espèce forestière africaine commercialisée sous les noms d’afrormosia ou d’assamela. Elle est une des principales espèces exploitées pour le bois d’œuvre en République Démocratique du Congo (RDC) et dans une moindre mesure au Cameroun et au Congo. Elle est au centre de nombreuses polémiques, notamment dans l’Union européenne, en ce qui concerne la durabilité de son exploitation. C’est une des rares espèces commerciales productrice de bois d’œuvre listée, depuis 1992, dans l’Annexe II de la CITES (Convention sur le commerce international des espèces en danger d’extinction) qui spécifie que « L'exportation d'un spécimen d'une espèce inscrite à l'Annexe II nécessite la délivrance et la présentation préalables d'un permis d'exportation ». Les plus grandes réserves d’afrormosia se trouvent en RDC. Cette thèse de doctorat porte sur l’écologie de cet arbre et sur son comportement vis-à-vis de l’exploitation forestière. Elle permet d’informer les organismes internationaux comme la CITES et les décideurs nationaux sur la vulnérabilité de l’afrormosia et de proposer des mesures à prendre pour que l’espèce ne soit pas menacée par une exploitation mal conduite et non régulée / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

Introduction<p><p>La drépanocytose, affection génétique concernant 1 à 2% de la population en Afrique sub-saharienne, est une maladie chronique dont l’un des traitements essentiels est la transfusion sanguine. Kisangani, une ville du Nord-est de la République Démocratique du Congo, compte environ un million d’habitants et près de 30 000 naissances par an. Elle est caractérisée entre autre par l’endémie malarienne, la fréquence élevée dans la population des virus de l’immunodéficience humaine (VIH), des virus des hépatites B (VHB) et C (VHC) et la carence d’autosuffisance en sang. Le don de sang est fait par des donneurs volontaires et par des donneurs de remplacement. Les tests VIH et VHB sont réalisés chez les donneurs depuis les années 80, celui de VHC depuis fin 2004. Dans ce contexte, définir des actions prioritaires pour assurer, en général et en particulier pour les patients drépanocytaires, la sécurité transfusionnelle la plus optimale possible est essentiel. <p><p>Méthodologie<p><p>Afin de déterminer les prévalences d’infections virales, les marqueurs sérologiques du VIH, VHB et VHC ont été recherchés chez 4637 donneurs de sang (2236 volontaires et 2401 de remplacement) du Centre Provincial de Transfusion et des hôpitaux de Kisangani. Chez 140 patients drépanocytaires suivis dans un centre médical de Kisangani, 127 ont été transfusés. Parmi eux, 79 sont « polytransfusés » et 94 ont été transfusés avant 2004. Outre la sérologie VIH, VHB et VHC, l’allo-immunisation anti-HLA et anti-érythrocytaire ont été recherchées et les indications de transfusion déterminées. Afin d’estimer la prévalence de la drépanocytose à la naissance, l’HbS a été identifiée systématiquement par focalisation isoélectrique sur du sang du cordon ombilical de 520 nouveau-nés suivis dans cinq maternités de Kisangani. Afin de déterminer les indications transfusionnelles dans la drépanocytose à Kisangani, un relevé de ces indications a été réalisé pour ces mêmes 127 patients drépanocytaires transfusés. Afin de comparer l’usage de la transfusion à Kisangani et à Bruxelles pour des complications non liées à l’environnement, les 140 patients drépanocytaires suivis à Kisangani ont été comparés à 195 patients suivis à Bruxelles ;parmi eux, 71 patients ont pu être appariés pour l’âge. <p><p>Résultats<p><p>La prévalence des marqueurs viraux chez les donneurs de sang est de l’ordre de 4% pour le VIH, de 5% pour le VHB et de 4% pour le VHC. Les séroprévalences de VIH (2,2 vs 4,1%) et VHB (3,0 vs 4,6%) sont moindres chez les donneurs bénévoles par rapport aux donneurs de remplacement. La prévalence du VIH et du VHB observée chez les donneurs bénévoles était plus élevée en 2006 qu’en 2004. Treize patients drépanocytaires non transfusés ne sont pas porteurs des marqueurs viraux. Six pourcent des patients qui ont une sérologie VHC positive sont des polytransfusés ;1% chez ceux qui avaient reçu une ou deux transfusions. Suite au retard d’introduction du dépistage VHC chez les donneurs, une séroprévalence pour le VHC de 7 % des malades pour seulement 0,7% pour celle du VIH et de 1,4% pour celle du VHB a été démontrée. Le fait qu’aucun patient transfusé après 2004, n’a été trouvé positif au VHC alors que 10 % l’ont été parmi ceux transfusés avant 2004 montre le bénéfice de l’introduction de moyens simples et peu coûteux. Deux (1,6 %) patients étaient porteurs d’anticorps anti-HLA et 13 (10%) des anticorps anti-érythrocytaires (2 anti-C-D, 1 anti-E et 1 anti-C-D-E). Aucun des patients n’étaient porteurs des anticorps anti-Kell (K), anti-Kidd (Jka et Jkb) ou anti-Duffy. La prévalence de la drépanocytose chez les nouveau-nés de Kisangani est d’environ 1 %. A Kisangani, outre l’anémie liée à la malaria (46 %), un facteur environnemental, 34 % des transfusions ont été administrées pour des crises douloureuses simples. En comparaison, aucun patient suivi à Bruxelles n’a été transfusé pour cette indication. Cette attitude est probablement à mettre en relation avec la méconnaissance de la maladie par le personnel médical et par les familles des malades. L’anémie chronique de ces patients est souvent mal connue et interprétée comme une anémie aiguë. <p><p>Conclusion<p><p>Un encouragement des dons bénévoles sans exclure les donneurs de remplacement est nécessaire pour continuer à accroître l’approvisionnement en sang. Afin d’améliorer la sécurité transfusionnelle, la généralisation des tests simples de dépistage des donneurs de sang comme ceux du VHC devrait constituer une priorité dans les centres de transfusion. Avec une prévalence d’environ 1%, la drépanocytose est une affection fréquente à Kisangani. Pour ces patients drépanocytaires, établir des recommandations concernant les indications transfusionnelles permettrait de leur éviter des transfusions inappropriées. <p><p>Abstract<p><p>Introduction <p><p>Sickle cell disease (SCD), a genetic disorder that affects 1% to 2% of the population in sub-Saharan Africa, is a chronic disease in which blood transfusion is one of the essential treatments. Kisangani, a town in north-eastern Democratic Republic of Congo, has about one million inhabitants and nearly 30 000 births per year. It is characterized among others by the endemic malarial, a high frequency in the population of human immunodeficiency virus (HIV), hepatitis B (HBV) and C (HCV) virus, but also a lack of self-sufficiency in blood. Blood donation is given by volunteers and replacement donors. HBV and HIV screening tests are performed in donors since the 80s, while for HCV it is available only since late 2004. In that context in view to ensure blood transfusion safety, it is essential to define priority actions, in general and especially for patients with sickle cell disease.<p><p>Methodology <p><p>To determine the prevalence of viral infections, serological markers for HIV, HBV and HCV were investigated in 4637 blood donors (2236 volunteers and 2401 replacement) of the Provincial Center of Transfusion and hospitals in Kisangani. Among 140 SCD-patients followed in a medical centre in Kisangani, 127 were transfused; 79 were considered as “multiple-transfused” and 94 were transfused before 2004. HIV, HBV and HCV seroprevalences, alloimmunization anti-HLA and against red blood cells were determined as well as the indications for transfusion. <p>To estimate the prevalence of SCD at birth, HbS was identified by isoelectric focusing on umbilical cord blood of 520 newborns in five maternities of Kisangani.<p>To determine the indications for transfusion in SCD patients at Kisangani, these indications were recorded for the 127 SCD transfused patients.<p>To compare the use of transfusion in Kisangani and in Brussels for clinical events unrelated to the environment, the 140 SCD-patients followed in Kisangani were compared with the 195 SCD-patients followed in Brussels and 71 patientsin both groups could be matched for age. <p><p><p>Results <p><p>The prevalence of viral markers among blood donors is around 4% for HIV, 5% for HBV and 4% for HCV. The seroprevalence of HIV (2.2 vs. 4.1%) and HBV (3.0 vs. 4.6%) were lower among volunteer donors compared to replacement donors. The prevalence of HIV and HBV infection observed among blood donors was higher in 2006 than in 2004.<p>Thirteen non-transfused sickle cell patients were not carriers of any serological viral marker. The SCD-patients HCV(+) were “multiple-transfused” patients (6%) or those who received one or two transfusions (1%). Following the delayed introduction of HCV donor screening, a HCV seroprevalence of 7% of patients for only 0.7% for the HIV and 1.4% for the HBV was demonstrated. The fact that no patients transfused after 2004 were HCV(+) compared to 10% of those transfused before 2004 shows the benefit of the introduction of a simple and inexpensive screening test. Two (1.6%) patients had anti-HLA antibodies and 13 (10%) red blood cells antibodies (2 anti-CD, 1 anti-E and an anti-C-D-E). None of the patients displayed Kell (K), Kidd (Jka and Jkb) or Duffy red cells antibodies.<p>The prevalence of sickle cell disease in newborns of Kisangani is about 1%. In Kisangani, in addition to anaemia due to malaria (46%), an environmental factor, 34% of transfusions were administered for uncomplicated painful crises. In comparison, no patient followed in Brussels were transfused for that indication. This attitude is likely to be related with the ignorance of the disease by the medical staff and patients’ families. The chronic anaemia of those patients is often poorly understood and interpreted as acute anaemia.<p><p>Conclusion<p><p>Encouragement of voluntary donations without excluding the replacement donors is needed to pursue to increase the blood supply. To improve blood safety, the generalization of simple tests for screening blood donors as those for HCV should be a priority in transfusion centres. With a prevalence of about 1%, the SCD is a common disease in Kisangani. For those SCD-patients, establish guidelines for indications of transfusion would avoid inappropriate transfusion.<p> / Doctorat en Sciences médicales / info:eu-repo/semantics/nonPublished

This master's thesis deals with the potential impact of natural resources on intrastate conflicts in Sub-Saharan Africa. The major aim is to investigate the general validity of the resource curse theory and of Ross's hypothesis about selling booty futures in civil wars. The presumed negative influence of both theories is tested on the cases of recent intrastate conflicts in the region, namely in Angola, the Democratic Republic of Congo, the Republic of Congo, Liberia and Sierra Leone. However, the main contribution of the thesis is probably the analysis of another case, namely Botswana, which, unlike other countries, appears to be out of the generally valid standards of the resource curse theory, as the only one experiencing long-term positive economic growth. The partial aim of the thesis is also to analyze the Botswana's success in managing natural resources and then to suggest some possible recommendations for other states in the region. The thesis is written in the qualitative approach, particularly in the form of thorough work with academic literature. The research method is the Method of Difference by John Stuart Mill, in its revised form of the Most Similar Systems Design.

The basic problem in this study is to determine whether the electoral management body (EMB) in the Democratic Republic of Congo (DRC) is sufficiently independent and whether it complies with most of the criteria of an ideal independent EMB in order to conduct free and fair elections in the promotion of democracy in the DRC. However, an ideal type of an independent EMB is not easily realizable but Ghana’s electoral commission (EC) is widely regarded as a model of an independent EMB in Africa. Therefore, this study uses the EC as a workable ideal type of independent EMB that informs this study in assessing the Independent National Electoral Commission (CENI)’s level of independence. The study discovered that while the formal legal framework guarantee the independence of the CENI, it lacks practical independence due to certain factors which include the mode of appointment and composition of the body, the unstable security of tenure of its members, the negative influence of the judiciary, executive and the parliament over the functioning of the CENI, and the lack of adequate funding. The study argues that the composition of the CENI has to be depoliticized; its members should enjoy a strong security of tenure and the issue of political parties funding should be effective and handled by the CENI in order to enhance political competitiveness in the electoral process. An adequate funding should be timely realized so that the CENI carries out its work with autonomy. The judiciary, the parliament and the executive should support the growth of democracy in the DRC by allowing the CENI to work without the interference of any quarter. / African Centre for Arts, Culture and Heritage Studies / M.A. (African Politics)
