Paysage électoral et stratégies de communication des candidats à la présidentielle de 2010 en Côte d'Ivoire / Electoral landscape and communication strategies of candidates for the 2010 presidential election in Ivory Coast.Palé, Titi Eri Aramatou 15 June 2017 (has links)
En 2010, les Ivoiriens organisaient une élection présidentielle au sortir d’une décennie de guerre civile. Depuis lors, ces élections défraient la chronique, en raison de leur issue critique : crise postélectorale meurtrière en 2011, réconciliation nationale poussive et, depuis 2016, mutineries dans les rangs d’une armée composite et de transition. La présente étude considère ces élections ivoiriennes de 2010 comme un objet d’étude scientifique et se consacre à la communication politique de campagne de trois « grands candidats » : Henri Konan Bédié du Parti Démocratique de Côte d’Ivoire (PDCI), Laurent Gbagbo de la Majorité Présidentielle (LMP) et Alassane Ouattara du Rassemblement Des Républicains (RDR). L’objectif scientifique est ici de déterminer les différents axes de communication partisane, qui éclairent le profil sociopolitique et le comportement de l’électeur ivoirien aux présidentielle de 2010. Plus spécifiquement, nos investigations sont consacrées, d’une part, à la détermination de l’électorat ivoirien dans sa composition sociale, politique et culturelle, mais aussi psychosociologique. Cet électorat est ici défini en termes d’intentions de vote, ou de motivation à voter pour tel ou tel candidat. D’autre part sont observés les moyens de communication utilisés par ces candidats majeurs qui deviennent des points structurants du champ politique ivoirien en s’endossant aux partis mandataires. Dans cette confrontation électorale pour capturer la majorité des voix interfèrent des représentations et des imaginaires politiques très marqués, qui consacrent ces candidats en challengers de la vie politique nationale et des sondages du moment. Ces enjeux affectent et différencient les stratégies de communication politique de campagne, que la thèse analyse en collectant les données et les ressources qui les influencent en sourdine et structurent autant les discours que les pratiques médiatiques des candidats étudiés. En clair, le contexte électoral de 2010 et ses déterminants sociohistoriques forgent les stratégies de communication et le comportement médiatique des candidats majeurs. / At the end of the year 2010, the Ivorians organized a presidential election after a decade of civil war. Since then, these elections are still in the news because of their critical outcome: murderous post-electoral crisis in 2011, complicated national reconciliation and, since the year 2016, mutinies in the ranks of a composite and transitional army. This study considers the Ivorian presidential elections of 2010 as a social sciences study subject and is devoted to the political campaign communication of three "great candidates" : Henri Konan Bédié of the Democratic Party of Côte d'Ivoire (PDCI), Laurent Gbagbo of the Presidential Majority (LMP) and Alassane Ouattara of the Rally of Republicans (RDR). The scientific purpose here is to determine the different axes of partisan communication, which illuminate the socio-political profile and behavior of the Ivorian voter in the 2010 presidential election. More specifically, our investigations are devoted, on the one hand, to the determination of the Ivorian electorate in its social, political and cultural composition, but also psycho-sociological dimension. This electorate is here defined in terms of voting intentions, or motivation to vote for a particular candidate. On the other hand are observed the means of communication used by these major candidates who become structuring points of the Ivorian political field by endorsing the mandatory parties. In this electoral confrontation to capture the majority of voices, the study shows how interfere a very strong political representations and imaginings, which consecrate these candidates into challengers of national political life and polls of the moment. These issues affect and differentiate campaign political communication strategies, which the thesis analyzes by collecting data and resources that influence them below and structure both the speeches and the media practices of the candidates studied. Clearly, the electoral context of 2010 and its sociohistorical determinants forge communication strategies and the media behavior of major candidates.

Les traités internationaux devant la juridiction constitutionnelle ivoirienne : contribution à l'étude du contrôle des traités en Côte d'Ivoire / International treaties before the Ivorian Constitutional Court : contribution to the study of the review of treaties in Côte d'IvoireAssi, Brou Rose Delima 24 November 2012 (has links)
La question des traités internationaux devant la juridiction constitutionnelle ivoirienne est une illustration du contentieux interne relatif au droit international conventionnel. Dans le cadre de ce contentieux relatif aux rapports entre le droit international et le droit interne, la juridiction constitutionnelle est amenée à se prononcer sur la constitutionnalité des traités internationaux avant leur insertion dans l’ordre juridique ivoirien. Les modalités d’introduction des traités internationaux en droit ivoirien traduisent l’option du pays en faveur de la doctrine moniste avec primauté du droit international. Les traités régulièrement ratifiés sont automatiquement incorporés au droit interne et ont, dès leur publication, une autorité supérieure à celle des lois internes. Cependant, avant leur ratification, la Constitution prévoit une procédure de vérification de leur constitutionnalité. Ce contrôle préventif a pour effet d’empêcher l'entrée dans l'ordre juridique ivoirien de tout traité international contraire à la Constitution, en dehors de l’intervention du pouvoir constituant. Si le traité est déclaré contraire à la Constitution, l’autorisation de le ratifier ne peut intervenir qu’après la révision constitutionnelle. Le mécanisme de contrôle mis en place par la Constitution de 1960 et reconduit par la Constitution de 2000 actuellement en vigueur a connu une évolution notable relativement à ses conditions d’exercice. Celles-ci ont été progressivement et considérablement élargies par les textes dans le but de faciliter et favoriser le déclenchement du contrôle…. Au total, la juridiction constitutionnelle n’a pu se pencher que sur une vingtaine de traités dont elle a, tant bien que mal, apprécié la conformité à la Constitution. Dans la confrontation de la norme internationale avec la Constitution, l’attitude du juge constitutionnel, emprunte parfois d’hésitations, repose largement sur une interprétation assez libérale de l’exigence de non-contrariété qui aboutit à faciliter la participation de l’État au droit international conventionnel en général et au droit communautaire africain en particulier. En effet, jusqu’ici, l’exercice du contrôle de la constitutionnalité des traités a révélé que, loin de constituer un « frein au développement du droit international », comme aurait pu laisser présager le mécanisme du contrôle, de façon générale, celui-ci s’avère plutôt favorable à l’influence du droit international. Seul le traité de Rome portant Statut de la Cour pénale internationale a été déclaré contraire à la Constitution par le Conseil constitutionnel dans sa décision du 17 décembre 2003. La révision constitutionnelle attendue en vue de la ratification du Traité de Rome permettra d’apprécier l’exécution des décisions de contrariété rendues par l’instance constitutionnelle. / The issue of international treaties before the Ivorian constitutional court is an illustration of the internal dispute relating to international treaty law. In the framework of this dispute concerning the relationship between international law and national law, the constitutional court is asked to decide on the conformity of international treaties before their integration in the Ivorian legal order. The conditions of integration of international treaties in the Ivorian domestic law reflect the country’s option in favor of the monist doctrine with primacy of international law. Treaties duly ratified are automatically incorporated into the national law and shall, upon publication, prevail over Acts of Parliament. However, before their ratification, the Constitution provides a procedure for the review of their constitutionality. The effect of this preventive review is to avoid the entry of unconstitutional international treaties into the Ivorian legal order without the decision and intervention of the constituent power. If the treaty is held not to be in conformity with the Constitution, authorization to ratify it may be given only after amending the Constitution. The mechanism of constitutional review established by the Constitution of 1960 and extended by the Constitution of 2000 (currently in force) undergone significant evolution regarding its conditions of implementation. These conditions were considerably widened in order to facilitate the release of control… In total, the constitutional court was able to look into only twenty or so treaties for which, somehow, the judge reviewed compliance with the Constitution. In the confrontation of treaties with Constitution, the attitude of the constitutional court is sometimes hesitant. Its interpretation of the requirement of non-contradiction between the treaty and the Constitution generally leads to facilitate the participation of the State to International law in general and African community law in particular. Indeed, so far, the practice of the constitutional review by the judge revealed that, the review, far from being an "obstacle to the development of international law", as could foreshadow its mechanism, is rather favorable to its development. Only the Treaty laying down the Statute of the International Criminal Court was declared not to be in conformity with the Constitution by the constitutional court in its decision of 17 December 2003. The amendment of the Constitution that is expected for the ratification of this treaty will be an opportunity to appreciate the enforcement of non-conformity decisions.

Schoemansdal : 'n Voortrekkergrensdorp, 1848-1868 / Schoemansdal : a Voortrekker border town, 1848-1868De Waal, Jochemus Johannes 02 1900 (has links)
Summaries in Afrikaans and English / Op 3 Mei 1848 het 'n aantll blanke nedersetters van Ohrigstad in Soutpansberg aangekom; 'n
pioniersdorp, onder Ieiding van Hendrik Potgieter, is gestig en primitiewe huise is opgerig. In
1855 het Stephanus Schoeman die Ieiding oorgeneem en die dorp na homself vemoem. Die
plaaslike owerheid het bestaan uit die kommandant-generaal, 'n landdros met heemrade en ander
regeringsamptenare sowel as dorpsbeamptes.
Tropiese koorssiektes het soms epidemiese afmetings aangcneem en talle mense het gesterf
soos die kerkhof met sy rye grafte getuig. Die nedersetters, gehard deur hul swerwersbestaan,
het die siektes en ontberings verduur.
Vir 16 van die 19 jaar was daar nie 'n vaste predikant nie tot ds N J van Wannelo in 1864 hom
in Schoemansdal gevestig het Hy het hom beywer vir die ophefftng van die inwoners op
geestelike en onderwysgebied. Die mense was konserwatief en meestal ongeletterd. Hulle was
bedagsaam, maar daar was ook ongure en opstandige persone. Hulle klere was eenvoudig en
meestal tuisgemaak, en hulle het graag sosiaal verkeer.
V erskeie beroepe is beoefen: houtsaery was betalend en hout was oorvloedig; jag was die
winsgewendste, want wild en olifante was volop en jagprodukte, veral ivoor waarvan tonne
verhandel is, het goeie markpryse behaal.
Die swartes wat reeds in die gebied gewoon het, het die blankes met wanttoue bejeen. Blankes
het hulle gevestig, grond toegeeien en onbeperk gejag, terwyl die swartes vir hulle moes werk
en belasting betaal. Ongehoorsame swart hoofmanne is aangeval, vee is gebuit en vrouens en
veral kinders is weggevoer as inboekelinge. Dit het tot openlike vyandelikhede gelei.
Veldtogte is gevoer, maar die blankes kon die swartes, weens hulle oninneembare vestings, nie
onderwerp nie. Die swartes het gewere op onwettige wyse bekom. Die handel het begin kwyn,
smouse en handelaars het weggebly en die inwoners het verann en onder mekaar getwis. Die
blankes het in die skans in Schoemansdal saamgetrek en Paul Kruger is met 400 man deur die
Transvaalse regering gestuur om die Venda te onderwerp. Die poging het misluk en op 15
Julie 1867 is Schoemansdal ontruim. Enkele maande later is 'n poging deur Schoeman aangewend
om die dorp te herwin, maar ook dit was onsuksesvol.
Schoemansdal sou nooit weer herbou word nie en was die eerste vesting wat die blankes aan
die swart meerdetheid sou oorgee. / May 1848 a number of white settlers from Ohrigstad arrived in the Soutpansberg. Under the
leadership of Hendrik Potgieter, a pioneer town was developed. In 1855 Stephan us Schoeman
replanned and renamed the town. The local government consisted of the commandantgeneral,
a landdrost, heemrade, government officials and town officers.
The region was unhealthy and fever stricken. Numerous graves in the graveyard are the tragic
signs of many deaths. However, hardy Trekkers, endured the sickness and hardships.
For 16 years there was no minister until, in 1864, the Rev Van Warmelo settled in Schoemansdal
and worked zealously for the spiritual and educational upliftment of the inhabitants.
Most people were conservative and illiterate. Their clothes were plain and usually home-made,
and they were very sociable.
There were different occupations. Woodcutters were well paid and wood was abundant.
Hunting was lucrative because there were plenty of wild animals and elephant, and hunting
products, especially ivory, had good market value.
Black communities, which already inhabited the area, distrusted the whites. The whites settled,
annexed the land and hunted wherever they wanted, while the blacks were compelled to work
and pay taxes. Military campaigns were undertaken against headmen who were regarded as
disobedient, livestock was seized, women, and children, were abducted under the indenture
system. All this caused open hostility.
Campaigns were launched against the blacks but they could not be subjected because of the
mountainous terrain. The blacks obtained weapons illegally. Trade deteriorated and the
whites became poorer and started to quarrel amongst themselves. The white inhabitants
moved into the fort and Paul Kruger was sent by the Transvaal government with 400 men to
force the Venda into submission. The attempt failed and on 15 July 1867 the town was
evacuated. Schoeman, with a small army, also made an unsuccessful attempt. Schoemansdal
would never be rebuilt and was the first white settlement to surrender to black majority. / History / D.Litt. et Phil. (Geskiedenis)

Thematic integrity in filmic versions of E.M. Forster's novelsHayes, Kalmia Joy January 1998 (has links)
This study discusses the extent to which Charles Sturridge's Where Angels Fear to Tread, Merchant Ivory's Howards End, and David Lean's A Passage to India have aimed at, and succeeded in, exploring the thematic concerns of E.M. Forster's novels. A brief introductory chapter explains the motivation behind this research, and the choice of critical methodologies used. It concludes with an outline of some of the problems confronting film-makers wishing to explore the concerns of novels. The first chapter, which is devoted to Where Angels Fear to Tread, reveals that while Sturridge is "faithful" to Forster's novel at a superficial level, basing most of his scenes on, and taking most of his dialogue directly from, the text, he does not explore Forster's themes. The facility with which film tells stories proves to be a treacherous trap for Sturridge. His version of Where Angels Fear to Tread is totally vacuous because he failed to develop anything beyond the story -- Forster's "tapeworm" of time (Aspects of the NoyeI41). The causality that Forster calls plot seemed beyond Sturridge's comprehension, leaving his film little more than an endless progression of "and then[s]" (Forster, Aspects 87). Characters are not given their full weight; symbols and leitmotifs are overlooked; the allegorical elements he did recognize, he failed to understand, and thus misplaced, so that the epiphanic moments of the novel are lost. There is no possibility of thematic concerns emerging from a film in which plot, characterization, symbol and rhythm are ignored. Sturridge's apparent inability to understand his source is in stark contrast to Merchant Ivory's sensitivity to Howards End, and their evident familiarity with literary criticism on the work. Chapter two explores the way in which their adaptation smooths out putative flaws in characterization and plot, and uses filmic rhythm and camera work to suggest comments made by the novel's narrator. Almost wholly successful in developing the novel's themes, Merchant Ivory's Howards End does not, however, successfully explore the spiritual dimensions of Forster's novel. Film is a medium capable of great subtlety, but its strength lies in its ability to capture the seen; the unseen tends to evade its grasp. It is in dealing with the unseen that Lean's A Passage to India misses greatness, for in virtually every other respect his version of Forster's masterpiece is superb. Chapter three explores Lean's creative and flexible approach to adaptation, his acute sensitivity to the differing demands of film and novel, and his confident technical mastery. It also explores, however, the emptiness at the heart of his film, an emptiness that is the result of his trivialization of the spiritual concerns of Forster's novel.

A sustainable livelihood framework for community-based tourism: a case of the African Ivory Route in Limpopo ProvinceLetsoalo, Josephine Mampheri 05 1900 (has links)
Inadequate attention has been paid to the complexity of rural livelihoods and the
dimensions of poverty. Although progress has been achieved in poverty reduction in
many countries over the years, statistics indicate that there is still much to be done.
Nearly half of the population of South Africa is poor. Sustainable Livelihood
Approaches see poverty reduction as achievable through diversification of livelihood
strategies. Communities can benefit from the development of tourism through
employment, financial gains, infrastructure creation and cultural revitalisation. While
fees charged for tourism activities have the potential to contribute to locals, they are
rarely controlled by them. The aim of this study was to formulate a Sustainable
Livelihood Framework for Tourism (SLFT) along the African Ivory Route. The study
involved fourteen villages near Fundudzi, Mtomeni and Nthubu camps which were
purposively selected as they represented the three main ethnic groups in the province.
Mixed method research design was used and included qualitative and quantitative
approaches. A 10% sample was selected from the total number of households.
Questionnaires, focus group and key informant interviews were used to collect data.
The data was analysed and presented in tables, graphs and maps. The perceptions
of the communities towards the African Ivory Route were both positive and negative.
The benefits included, improved network, community empowerment and development
of infrastructure. The constraints included, conflicts, mistrust, political interference and
power struggle among the various institutions. The study concluded that the African
Ivory Route has not achieved sustainable livelihoods outcomes for the concerned
communities. The recommendation was that frameworks for maximising benefits from
tourism were necessary to directly support community development. Communities, Institutions, Tourists and Environment (CITE) framework was conceptualised to
assess the best way for attaining positive sustainable livelihoods outcomes. / Geography / Ph. D. (Geography)

Financial liberalisation and economic growth in ECOWAS countriesOwusu, Erasmus Larbi 05 1900 (has links)
The thesis examines the comprehensive relationship between all aspects of financial liberalisation and economic growth in three countries from the Economic Community of West African States (ECOWAS). Employing ARDL bounds test approach and real GDP per capita as growth indicator; the thesis finds support in favour of the McKinnon-Shaw hypothesis but also finds that the increases in the subsequent savings and investments have not been transmitted into economic growth in two of the studied countries. Moreover, the thesis also finds that stock market developments have negligible or negative impact on economic growth in two of the selected countries. The thesis concludes that in most cases, it is not financial liberalisation polices that affect economic growth in the selected ECOWAS countries, but rather increase in the productivity of labour, increase in the credit to the private sector, increase in foreign direct investments, increase in the capital stock and increase in government expenditure contrary to expectations. Interestingly, the thesis also finds that export has only negative effect on economic growth in all the selected ECOWAS countries. The thesis therefore, recommends that long-term export diversification programmes be implemented in the ECOWAS regions whilst further investigation is carried on the issue. / Economics / D.

Impact of changing environments on West African rainforest amphibian communities and their parasites in Ivory Coast. / Auswirkungen von Umweltveränderungen auf Westafrikanische Amphibien-Gemeinschaften und deren Parasiten in der ElfenbeinküsteKpan, Tokouaho Flora 27 June 2022 (has links)
Umweltveränderungen durch natürliche und/oder menschliche Einflüsse (insbesondere der Verlust und die Fragmentierung von Lebensraum) sind wichtige Faktoren, die zum weltweiten Artenschwund beitragen. Einer der entscheidendsten Beiträge zum weltweiten Rückgang der biologischen Vielfalt, ist der kommerzielle Holzeinschlag. Insbesondere in tropischen Regenwäldern, etwa in Westafrika, ist dies besonders besorgniserregend, da wenig untersuchte, diverse Wirbeltiergemeinschaften von einem starken kommerziellen Holzeinschlag betroffen sind. Frühere Studien haben bereits die negativen Auswirkungen großflächiger Abholzung auf die taxonomische und funktionale Vielfalt von Amphibiengemeinschaften, aber auch auf die Gesundheit von Individuen identifiziert. Umweltveränderungen können sich also auch nachteilig auf eine Wirts- Parasit-Beziehung auswirken, was nicht zuletzt zu einer verringerten Überlebensfähigkeit der Wirtsarten führen kann. Die Untersuchung der Auswirkungen von Störungen Abholzung und Umweltveränderungen auf Amphibien, sowie auf bestehende Wirts-Parasiten-Beziehungen sind daher von größter Bedeutung um nachhaltige Waldwirtschaft und zukünftige Naturschutzmaßnahmen planen zu können.
In dieser Arbeit möchte ich mittels eines Regenerationsgradienten nach einer Störung (Abholzung) untersuchen, wie sich die Dynamik einer Amphibiengemeinschaft verschiebt und wie diese Störung die Wirts-Parasit-Beziehung beeinflusst. Ich verwende einen kombinierten Datensatz (Amphibie [Wirt], Milbe [Parasit] und Umweltbedingungen [Habitat]) der über zwei Zeiträumen im Abstand von 15 Jahren (1999-2000 und 2016-2017) an identischen Standorten (vor 45 Jahren abgeholzter Wald und Primärwald) im Taï-Nationalpark (TNP) in der Elfenbeinküste gesammelt wurde, um die Anpassungsfähigkeit von Fröschen und ihren Parasiten an sich ändernde Umgebungen zu untersuchen.
In einem ersten Artikel unterstreiche ich die Bedeutung auch kleiner Waldgebiete als potenzielle Quellen für unbeschriebene Biodiversität. In einem kleinen, nie zuvor untersuchten Sumpfwald in der südöstlichen Elfenbeinküste fand ich eine neue Blattstreufroschart der Gattung Phrynobatrachus. Anhand charakteristischer morphologischer Merkmale, einer beträchtlichen, molekulargenetischen Distanz zu anderen westafrikanischen Phrynobatrachus-Arten, sowie eines individuellen, männlichen Anzeigerufes beschreibe ich Phrynobatrachus tanoeensis sp. nov. als eine für die Wissenschaft neue Art.
Im zweiten Artikel untersuche ich die Widerstandsfähigkeit westafrikanischer Frösche in Wäldern, die vor über 45 Jahren selektiv abgeholzt wurden. Ich vergleiche die Diversität, Abundanz, Zusammensetzung und den Lebensraum von Amphibiengemeinschaften in abgeholzten und Primärwäldern innerhalt zweier Zeiträume (2000 und 2016- 2017). Ich konnte herausarbeiten, dass sich die Struktur des zuvor abgeholzten Waldes im Laufe von 45 Jahren langsam der des Primärwaldes annäherte, wobei die sichtbarsten Veränderungen in den letzten 15 Jahren auftraten. Während ich 30 Jahre nach dem Holzeinschlag zwar keine Unterscheide mehr in der Diversität und Abundanz der Amphibiengemeinschaft zum Primärwald feststellen konnte, beobachtete ich jedoch eine fortschreitende Konvergenz der Zusammensetzung der Amphibiengesellschaften in beiden Waldtypen. In den zuvor abgeholzten Wäldern erholten sich mehrere waldspezialisierte Arten (FS), während die Zahl mehrerer Generalisten (FG) über den 15-jährigen Probenahmezeitraum stetig abnahm. Diese Ergebnisse deuten darauf hin, dass 45 Jahre nach der Abholzung der gestörte Lebensraum allmählich die Heterogenität des ungestörten Lebensraums annimmt, der in der in der Lage ist die originale Amphibiengemeinschaft aus Waldspezialisten (FS) zu erhalten.
Im dritten Artikel untersuche ich die Faktoren, die zu einem erhöhten Milbenbefall in den Amphibiengesellschaften des TNP führen. Ich fand heraus, dass die Wirts-Parasit-Beziehung zwischen Milben der Gattung Endotrombicula sehr spezifisch auf Frösche der Gattung Phrynobatrachus zugeschnitten ist, da offensichtlich nur die vier Arten P. phyllophilus, P. alleni, P. villiersi und P. plicatus befallen werden. Ebenso zeigte sich der Milbenbefall abhängig von der Art (höchste Prävalenz bei P. phyllophilus gefolgt von P. alleni), des Geschlechts (höhere Prävalenz bei Männchen als bei Weibchen, sowohl bei P. alleni und P. phyllophilus), des Alters (höhere Prävalenz bei Erwachsenen als bei Jungtieren in P. alleni) sowie der Jahreszeit (höhere Prävalenz während der Regenzeit im Vergleich zur Trockenzeit bei P. phyllophilus). Ich diskutiere diese Ergebnisse mit Bezug auf die Ökologie der Endotrombicula-Milben, die stark von feuchten Bedingungen abhängig sind, sowie die Überschneidung dieser Bedingungen mit denen der Wirtsfroscharten überschneiden. Des Weiteren beobachtete ich, dass die Prävalenz des Milbenbefalls in den letzten 15 Jahren (1999-2000 bis 2016-2017) abgenommen hat. Dieser steht möglicherweise im Zusammenhang mit den lokalen Auswirkungen des Klimawandels, was die in den letzten Jahren deutlich zurückgegangenen Niederschläge erklären würde.
Meine Arbeiten zeigen, dass das Verständnis der Vielfalt westafrikanischer Amphibien noch lange nicht vollständig ist. Es zeigt sich, dass weiterhin Forschungsarbeit geleistet werden muss, um den tatsächlichen Amphibienreichtum besser abschätzen zu können. Darüber hinaus habe ich gezeigt, dass sich Amphibiengemeinschaften in abgeholzten Wälder zurück zum ursprünglicheren Zustand regenerieren können, was die Bedeutung unterstreicht, genutzten Wäldern ausreichend Zeit zu lassen, um sich zu regenerieren. Ob die Milbenprävalenz tatsächlich auf Grund des Klimawandels abnahm, sollte in Zukunft genauer untersucht werden. / Environmental changes due to both natural phenomena and/or human disturbance (i.e. habitat loss, disturbance and fragmentation) are important factors contributing to global species declines. Commercial logging is amongst the greatest contributor to this disturbance resulting in widespread biodiversity declines. In tropical rainforests, particularly those of West Africa, this is particularly troubling as diverse vertebrate assemblages are subject to heavy commercial logging. Previous studies have identified negative impacts of these logging practices on the taxonomic and functional diversity of amphibian communities and species. Furthermore, logging and other environmental changes may affect host-parasite interactions, resulting in exacerbated negative impacts of these pressures and reduced survivability of host species. As such, determining the effects of logging on amphibians, their subsequent recovery following selective logged forest, and the effects of environmental change on host-parasite relationships, will be paramount for informing future conservation action.
In this thesis, I aim to determine how amphibian community dynamics shift over a regeneration gradient following disturbance (logging), and how this disturbance influences amphibian-parasite interactions. I use combined data sets (amphibian, parasite and habitat) from two time periods 15 years apart (1999-2000 and 2016-2017) collected in identical sites (logged forest since 45 years and old growth forest) within Taï National Park (TNP) Ivory Coast, in order to examine the adaptive capacities of frogs and their parasites to changing environments.
In the first paper, I underline the importance of forest, even small, as potential source of undescribed biodiversity. In that small swamp forest, never survey before located in southeastern Ivory Coast, I found a new leaf-litter species of the Phrynobatrachus genus. Based on morphological characteristics, considerable molecular genetic distance to other West African Phrynobatrachus species, as well as advertisement calls, I describe Phrynobatrachus tanoeensis sp. nov. as a species new to science.
In the second paper, I investigate the resilience of West African frogs in forests selectively logged over 45 years ago by comparing data (amphibian diversity, abundance, composition and habitat) from previously logged and old growth forest over two time periods (2000 and 2016-2017). I found that the structure of previously logged forest slowly recovered toward old growth forest states over the course of 45 years, with most visible changes occurring in the last 15 years. I also found no changes in amphibian diversity and abundance in the previously logged forest over time but observed a progressive convergence of amphibian composition in previously logged forests toward that of unlogged forest amphibian communities. In contrast, several forest specialist species (FS) recovered, whilst forest generalist (FG) species declined in the previously logged forest over the 15 years sampling period. These findings suggest that 45 years since logging activities the previously logged forest gradually provides habitat heterogeneity capable of maintaining FS amphibian species and more intact amphibian communities.
In paper 3, I investigate the factors leading to increased mite infestation in the amphibian assemblages of TNP. I found that mites of the Endotrombicula genus seem to be specific to Phrynobatrachus frogs and infested only four leaf-litter species (P. phyllophilus, P. alleni, P. villiersi and P. plicatus). I also found that mite infestation was associated with species (highest prevalence in P. phyllophilus followed by P. alleni), sex (higher prevalence in males than females in P. alleni and P. phyllophilus), age (higher adult prevalence than juveniles in P alleni) as well as season (higher prevalence during the wet compared to the dry season in P. phyllophilus). I discuss these findings with reference to the ecology of Endotrombicula mites which rely heavily on humid conditions, conditions which overlap with the reproductive requirements of the host taxa. Additionally, I observed that the prevalence of mite infestation decreased over the last 15 years (1999-2000 to 2016-2017). This decreased mite infestation over time is potentially linked to local climate change, which exhibited distinctly lower rainfall in recent years.
These studies show that West African amphibian diversity is far to be complete. Thus, more survey work needs to be done in order to have an idea of amphibian richness. Additionally, I showed that to environmental changes in the context of recovery following logging have a positive impact on amphibian. Forest amphibian community recovers in the previously logged forest, which highlight the importance to leave those forest to regenerate. However, although mite prevalence decreased over time, future research of post logging restoration and climate change impact on mite prevalence need be more investigate.

King Leopold II's Exploitation of the Congo From 1885 to 1908 and Its ConsequencesJohnson, Steven 01 August 2014 (has links)
This thesis argues that King Leopold II, in his exploitation of the Congo, dealt the Congo a future of political, ethnic, and economic destabilization. At one time consisting of unified and advanced kingdoms, the Congo turned to one completely beleaguered by poverty and political oppression. Leopold acquired the Congo through unethical means and thus took the people's chances away at self-rule. He provided for no education or vocational training, which would stunt future Congolese leaders from making sound economic and political policies. Leopold also exploited the Congo with the help of concession companies, both of which used forced labor to extract valuable resources. Millions of Congolese died and the Congo itself became indebted through Belgian loans that were given with no assurance they could ever truly be paid back due to the crippled economy of the Congo. With the Congo now in crippling debt, the current president, Joseph Kabila, has little incentive to invest in reforms or public infrastructure, which stunts economic growth.1 For over a century the Congo has been ruled by exploitative and authoritarian regimes due to Leopold's initial acquisition. The colonization from Leopold lasted from 1885-1908, and then he sold it to his home country of Belgium who ruled the Congo from 1908 to 1960. Belgium helped prop up a dictator named Joseph Mobutu or Mobutu Sese Seko who ruled from 1965 to 1997. Afterwards he was overthrown by the Kabila family who has continued the exploitative rule and has made no significant efforts at democratization or reforms. Thus the ethnic conflicts, political oppression and economic woes that the Congo is facing today are inevitably linked to its Leopoldian past.

Toward a Rhetoric of Scholar-FandomCochran, Tanya R. 01 December 2009 (has links)
Individuals who consider themselves both scholars and fans represent not only a subculture of fandom but also a subculture of academia. These liminal figures seem suspicious to many of their colleagues, yet they are particularly positioned not only to be conduits to engaged learning for students but also to transform the academy by chipping away at the stereotypes that support the symbolic walls of the Ivory Tower. Because they are growing in number and gaining influence in academia, the scholar-fans of the television series Buffy the Vampire Slayer (Buffy) and other texts by creator Joss Whedon are one focus of this dissertation. Though Buffy academics or Whedon scholars are not the only ones of their kind (e.g., academic- fan communities have cropped up around The Simpsons, The Matrix Trilogy, and the Harry Potter franchise), they have produced more literature and are more organized than any other academic-fan community. I approach all of my subjects—fandom, academia, fan-scholars, and scholar-fans—from a multidisciplinary perspective, employing various methodologies, including autoethnography and narrative inquiry. Taking several viewpoints and using mixed methods best allows me to begin identifying and articulating a rhetoric of scholar-fandom. Ultimately, I claim that Whedon academic-fans employ a discourse marked by intimacy, community, reciprocity, and transformation. In other words, the rhetoric of Whedon scholar-fandom promotes an epistemology—a way of knowing—that in Parker J. Palmer’s paradigm is personal, communal, reciprocal, and transformational.
