The Intergovernmental Authority on Development (!GAD) has played a major role in conflict resolution in the Sudan. The strength of the !GAD Peace Initiative particularly has been its clarity in identifying the key issues at the core of the conflict in its Declaration of Principles (DoP). From that time the Sudan People's Liberation Movement/ Army (SPLM/A) and Government of Sudan (GoS), though later, embarked on a path to seek a negotiated settlement to the conflict. Another achievement had been IGAD's ability to help Sudan pool its resources that seemed to provide an answer to the perennial power constraints that bedevil African mediators. It is without doubt that the Machakos protocol signed in July 2002 was a breakthrough for the history of IGAD's conflict resolution in Sudan, because of the acknowledgement, for the first time, of the right of self-determination for the south, and the guarantee of the right to opt for self-determination through a referendum at the end of a six-year interim period. From this time IGAD's mediators became more flexible, the Sudan peace process moved speedily and to the highest level; and between 2002 and 2003, the substantive agreements were signed, leading to the final agreement in 2005. At the same time, the hard-pressed role of the United States cannot be undermined for real progress in the IGAD peace process in Sudan. Furthermore, though IGAD faced a lot of challenges as the parties' willingness to negotiate correlated with their military successes and failures, the organization commitment in the peace process assisted in achieving IGAD's stated objective. Its also worth noting that there was a lack of inclusivity in the IGAD negotiations and the mediators at times were unable to articulate common visions of their roles and sustain adequate attention to their intervention; however, despite several competing mediation attempts such as the "Joint Libya-Egyptian Initiative" (JLEI), IGAD has provided the by and large undisputed negotiation framework for the Sudan conflict since the mid-nineties. Crucial and worthy as this achievement is that, the IGAD Initiative will engross a continuing involvement in Sudan that would not end until the terms of the peace agreement are fulfilled and the necessary stability is achieved, because only then would there be confidence that peace would be secure. This objective is not realisable unless there are significant and continuing democratic reforms; IGAD must understand that this objective is an integral part of the peace process. Finally, IGAD's continued engagement with the Joint IGAD Partners and the international community as a whole to provide for support for peace building and reconstruction in Sudan is imperative. If peace is consolidated in the South, it will demonstrate the benefits of negotiated solutions to other parts of Sudan, such as Darfur and the East. / M.Soc.Sc.

The purpose of this research was to do applied study to investigate TVET teacher education in Sudan in a bid to rebuild and raise the capacity of the teachers and trainers who are working in the technical schools and vocational training centers in Khartoum state, and to generalize the overall results throughout the Sudan. Specifically, many research questions were addressed to target the main purpose of the study: To what extent the practical components of curriculum are applied in and outside TVET institutions? To what extent the in-service training’s programs meet the professional development of teachers and trainers? Is the private sector contributes to the training programs? Which approaches could be implemented to improve the teacher training? To what extent the integration of ICTs in learning and teaching process improves competence of TVET teachers? Is there re-training program for old teachers? Is there need to train teacher in private sector workshop? Moreover: the following concepts are relevant to raising the capacity building of teachers are studied: teacher professional development, capacity building, integration of suitable level of information and communication technology (ICT) to teacher education and the connectivity of training process to world of work. In order to collect convenient information, the study used the questionnaire and interview as instruments to achieve the objectives of the research. The main population of the study is teachers, trainers, administrators and employers. With respect to data analysis, the study used the SPSS program and the Chi-square to test some hypotheses. The results of the study showed that essential innovations and reforms on the initial and in-service training programs should be done especially, respect to practical components of the initial and in-service training to reach the professional development for teachers. Since most of interviewees confirmed old curricula of the initial education of teacher and there was no retraining program for the teacher on the job: the linkage of the training to world of work is needed to keep the teacher up-to date. Integration of ICT into learning/teaching process is very important factor because it’s one of the modernization requirements; hence if we do not do this now it should be urgent necessity at the near future. Major result of the study the proposed training approach for TVET teachers in Sudan, whereas implementation of this approach depends on three levels: macro- level the political commitment by undertaking clear national policy and conceptual framework for technical and vocational education and improving the image of teachers, their work conditions and media involvement. Meso-level:(public and private sector): since a moral contribution towards training of TVET teachers should be realized, by providing real opportunity to make a success to this new training approach by means of offering technical support, technical consultation, advanced knowledge, specialized seminars and contributing of all training policies especially the financial cost. Micro-level (TVET institutions): there is vital role of administrators to play to attract best candidates not only students of low grades to TVET domain. For example, integrate simple level technology into curricula. Improve initial and in-service training programs based on training needs assessment. Create good internship, and improving the work environment and incentives for teachers.

Eine wissenschaftliche Exkursion in den Blue Nile State der Republik Sudan im Jahr 2011 vermittelte einen Überblick über die forst- und holzwirtschaftliche Situation der Region. In den verbliebenen Naturwäldern führt der Nutzungsdruck seitens der örtlichen Bevölkerung zu einer starken Degradierung. Hauptbaumart der Wirtschaftswälder ist Acacia nilotica. Die Sägeindustrie des Landes konzentriert sich auf die Verarbeitung dieses Holzes zu Eisenbahnschwellen. Im Bereich Möbeltischlerei spielen einheimische Laubholzarten eine gewisse Rolle. Daneben wird europäisches Nadelholz importiert. Um die Entwicklung der Region zu fördern, muss das Ziel der weiteren Forschungsarbeit eine zielgerichtete und nachhaltige Bewirtschaftung und Nutzung der forstlichen Ressourcen sein.

Acacia species producing gum Arabic are of great (socio)-economic, and ecological importance in Sudan. Insect attacks are one of the main causal agents in the decline in the gum Arabic yielding trees. Infested trees are almost totally damaged if the infestation is left untreated. The beetle family Cerambycidae is one of the largest groups of insects. Commonly referred to as long-horned beetles, these pests destroy host trees, having a great affect during times of drought. Many studies have been completed about the effect of long-horned beetles in various global settings. However, in Sudan, there is limited information about the insects’ ecological, biological, and even basic, profile. Thus, in this dissertation I study the spectrum, relative abundance, and phenology of the long-horned beetle species that are infesting Acacia species in Kordofan region (Sudan). Seven species were recorded using interception traps. These included Anthracocentrus arabicus (Thomson, 1877), Crossotus strigifrons (Fairmaire, 1886), Crossotus subocellatus subocellatus (Fairmaire, 1886), Doesus telephoroides Pascoe, 1862, Gasponia gaurani Fairmaire, 1892, Titoceres jaspideus (Serville, 1835) and Tithoes sp.. Two species were recorded using ground - photoeclectors: Crossotus albicollis (Guérin, 1844) and Coelodon servum White, 1853. Most of the species are known from other Arabian and African countries. However Coelodon servum White, 1853, Doesus telephoroides Pascoe, 1862, and Gasponia gaurani Fairmaire, 1892 were recorded in this study for the first time in Sudan. Results from flight interception traps indicated peak activity density of long-horned beetles during the rainy season (June – September), with maximum occurrence in June and peak occurrence in August. All study sites showed infestations of long-horned beetles, but the level of infestation varied between sites and Acacia species. The El Demokeya reserve forest indicated the highest percentage of infestation out of all the sites surveyed in this study. The infestation ranged between 57.1% and 100.0% for Acacia senegal, between 5.9% and 26.7% for Acacia mellifera, and 0% to 23.1% for Acacia seyal study sites. Acacia species differed also with respect to the spatial infestation pattern. Results indicated the maximum (95.5%) presence of holes of infestation in the branches of A. senegal when compared to the trunk. Holes of infestation were recorded in all directions, with a minimal occurrence on the south side (18.2%). Opposite results were obtained for A. mellifera with the maximum number of holes in the trunks (46.2%), while branches were less affected. In addition results obtained showed no presence of holes in the branches of A. seyal. Moreover, this study focuses on the assessment of tree characteristics that may trigger the infestation. Logistic regression indicated that tree age was the only predictor for the infestation with long-horned beetles – at least for Acacia senegal. A significance difference was obtained for the stand height curve between non-infested and infested trees of Acacia species, except A. senegal stands at El Demokeya. The study was supplemented by qualitative data, produced from a survey of gum landowners. This questionnaire indicated the level of awareness that gum landowners had with regard to long-horned beetles and their infestations. The results of this survey denoted that 95.0% of gum farmers were aware of the long-horned beetles, while 49.2% indicated an awareness about infestations, mentioning the emergence holes as damage characteristics.

Esse trabalho propõe-se a uma investigação histórica do longo processo que originou o Estado do Sudão do Sul, tornado independente em 2011 após plebiscito. Para tanto, buscamos traçar uma longa história do Sudão, do bilad al-sudan oriental aos dias atuais. Nos apoiamos, principalmente, em algumas obras da extensa historiografia do Sudão para desenhar esse quadro contextual de nosso objeto de estudo. Apresentado o palco, buscamos interpretar os eventos, as relações políticas e sociais e mudanças econômicas e culturais a afetar o Sudão, depois Sudão do Sul em sua intricada relação com seus vizinhos regionais e as potências globais. Terminamos nosso trabalho apresentando algumas notas e reflexões acerca de temas mais precisos, como “construção nacional”, “uso político da identidade étnica”, e o “papel das elites” no Sudão do Sul, dentre outras. / This work is the result of a historical investigation of the long process that originated the State of South Sudan, independent in 2011 after a national referendum. We sought to draw a long history of Sudan, from the eastern bilad al-sudan to modern days. We based our work mostly on some of the broad historiography on Sudan, from which to develop a contextual idea of our object of study. Having set the stage, we sought to interpret the events, political and social relations and economic and cultural changes that have affected Sudan and later South Sudan in their intrincate relation with regional neighbors and global powerhouses. Our work concludes presenting some observations ad reflections concerning specific issues, such “nation-building”, “political use of ethnic identity” and the “role of elites” in South Sudan, among others.

Corantes e pigmentos são utilizados no mundo todo para alterar a percepção visual de diversos bens de consumo. Dentre esses compostos se destacam os corantes que possuem grupamentos azo ou nitro como cromóforo. Muitas dessas substâncias são potencialmente tóxicas, seja na sua forma original seja após a biotransformação, com ênfase aos efeitos mutagênicos e/ou carcinogênicos. Este trabalho teve como objetivo investigar as rotas metabólicas e avaliar o perfil toxicológico parcial dos corantes Disperso Amarelo 9 e Sudan III. O Sudan III é um corante azóico e que embora tenha estrutura química muito semelhante ao Sudan I, um carcinógeno humano, existem poucos dados na literatura a respeito de sua toxicidade. Vale ressaltar que o Sudan III é um corante de alimentos banido da maioria dos países, porém tem sido repetidamente detectado em alimentos industrializados como adulterante. Já o corante Disperse Yellow 9 é amplamente utilizado principalmente pelas indústrias têxteis, porém não foram encontrados dados na literatura sobre seu potencial tóxico. Foram realizados estudos espectroeletroquimicos capazes de simular reações de oxidação e redução que ocorrem em organismos vivos, além de sistema exógeno de metabolização (S9). A mutagenicidade dos corantes foi avaliada pelo ensaio de Samonella (utilizando as linhagens TA98, TA1535, TA100 e YG1042, com e sem S9) e por meio da avaliação da capacidade de ligação com o DNA e a guanosina in vitro. Ainda, verificou-se a indução de morte celular em condrócitos bovinos. Nossos resultados mostraram que as condições de oxidação (eletroquímica ou após a reação com S9) e redução foram capazes de modificar o grupamento cromóforo tanto do corante Sudan III quanto do Disperso amarelo 9, e esse efeito é esperado em organismos vivos, podendo formar derivados tóxicos. O corante Sudan III é capaz de se ligar ao DNA de forma estável, mais especificamente com a base nitrogenada guanosina, enquanto o Disperso Amarelo 9 se liga fracamente ao DNA e não com a guanosina. O corante Sudam III exibiu fraca mutagenicidade e apenas com a linhagem TA1535. Por outro lado, Disperso Amarelo 9 foi positivo para as linhagens TA1535 e YG1042, e o efeito foi mais pronunciado após a ativação metabólica. Ambos os corantes induziram à morte dos condrócitos de forma tempo e concentração dependente. Assim, ambos os corantes foram considerados tóxicos, tanto na sua forma original quanto após biotransformação e podem levar a riscos à saúde humana e ao ecossistema quando de sua exposição. / Dyes and pigments are applied worldwide to change the visual perception of many products. Among these compounds, dyes containing azo and nitro bond as chromophore are very important groups. A wide range of these substances are potentially toxic either in its original form or after biotransformation leading to mutagenic / or carcinogenic effects. The aim of the present study was to investigate the metabolic pathways involving the chromophore group and also to evaluate the toxicological profile of Disperse Yellow 9 and Sudan III dyes. Sudan III is an azo dye that has a very similar chemical structure to Sudan I a known carcinogen. Despite, there are few data about Sudan III toxicity in the literature. It is important to point out that Sudan III is banned from most worldwide food industry it has been frequently detected as an adulterant in a large amount of processed food. The literature has no information about the toxicity potential of Disperse Yellow although it is widely and mainly used by textile industries. On the present we performed a spectroeletrochemical method capable of simulating bio- reactions able to occur on living organisms such as oxidation and reduction, also exogen metabolization system (S9) were applied. The mutagenicity of the dyes was evaluated by Salmonella assay (using strains TA98, TA1535, TA100 and YG1042, with and without S9). The ability of causing stable bonds to DNA and guanosine were also tested in vitro. Also the capacity of inducing cell death on bovine chondrocytes was investigated. Our results indicated that the oxidation reactions (spectroeletrochemical method or after S9 reaction) and also the reduction reactions were able to modify the chromophore group for the studied dyes Sudan III and Disperse Yellow 9, this effect could be expected in living organisms and may also generate toxic products. Sudan III is capable of binding to DNA and forming stable aducts, specifically to the nitrogenated base guanosine, while Disperse Yellow 9 binds weakly to DNA and does not react with guanosine. Low mutagenicity was observed for strain TA1535 for Sudan III dye. Besides, strains TA1535 and YG1042 gave positive responses for Disperse Yellow, the effect was pronounced after metabolic activation. Death of chondrocytes was observed for both dyes demonstrating time and concentration dependency. Toxicity was observed for both dyes, before and after biotransformation, this effect may lead to risks on human health and also for the environment.

Since Sudan’s Comprehensive Peace Agreement (CPA) was signed in 2005, its border with Uganda has become a hub of activities. These economic activities have been enhanced by ethnic and political relations, but also by diplomatic relations between the two countries. Contrasting developments on the Ugandan side of the border with those on the South Sudanese side, this research draws on empirical fieldwork to examine the impact of diplomatic relations on the development between both countries since 2005, with international trade as the main aspect of development. The study sets out to show how trade between both countries has been affected by the diplomatic relations between them. The post-CPA demand for goods and state-building processes created a range of economic opportunities for traders. This was particularly the case for Ugandan large-scale traders who, as a result, became an important and empowered group. These factors have further been enhanced by good diplomatic relations between both countries, and as a result South Sudan has become Uganda’s most important trading partner as well as a destination for many Ugandans to conduct their trade. Simultaneously, post-conflict problems have emerged in South Sudan such as insecurity, weak government institutions run by incompetent officials, corruption, high foreign exchange rate, cultural diversity, mistrust and poor infrastructure. These problems have emerged as major challenges to trade and investment by Ugandan traders in South Sudan with traders as well as government officials agreeing that these challenges present major setbacks to trade and investment in South Sudan. Ugandan small-scale traders in particular have become more vulnerable to expressions of authority on the part of South Sudan’s post-CPA state, in which state or individual military might is used effectively to control trade. The current conflict, which began in December 2013, has added a new dimension to the list of impediments to trade as insecurity and economic instability have precipitated an atmosphere of uncertainty among many traders and investors. Despite all those challenges, Ugandan traders as well as government officials still view South Sudan as a business destination of choice. Overall, the study confirms that diplomatic relations have enhanced international trade between South Sudan and Uganda by way of solving trade disputes, investment promotion and influencing leadership on policy matters.
