The loving heart of a mother or a greedy politician? : media representations of female presidents in Liberia and Malawi
2016
Pro gradu-tutkielmassani tarkastelen miten kahta afrikkalaista naispresidenttiä - Liberian presidentti Ellen Johnson Sirleafiä, ja Malawin presidentti Joyce Bandaa on kuvattu mediassa. Tutkimuksen tarkoituksena on ymmärtää miten eri medialähteet(malawilaiset, liberialaiset, afrikkalaiset ja kansainväliset mediat) ovat kuvanneet kahta naispresidenttiä, ja miten naispresidentit ovat tuoneet itsensä esille mediassa. Tutkimuskysymykset ovat keskittyneet sukupuoleen ja johtajuuteen: 1) miten sukupuoli on määritellyt afrikkalaisten naispresidenttien poliittisen johtajuuden englanninkielisten medialähteiden pohjalta? 2.) miten sukupuoli on määritellyt kyseisten presidenttien esittämisen mediassa? …
Modeling red coral (Corallium rubrum) and African snail (Helixia aspersa) shell pigments: Raman spectroscopy versus DFT studies
2016
Pigments from red coral (Corallium rubrum) and African snail (Helixia aspersa) shell were studied non-invasively using Raman spectroscopy with 1064-nm laser beam. The two observed bands because of organic pigments confined in biomineralized CaCO3 matrix at about 1500 and 1100 cm−1 were assigned to ν(C[DOUBLE BOND]C) and ν(C―C), respectively. Both signals originate from polyene(s) of largely unknown structure, containing several conjugated C[DOUBLE BOND]C bonds. The small peak at 1016 cm−1 in the Raman spectrum of coral pigment was assigned to in-plane ―CH3 rocking or structural deformation of polyene chain because of spatial confinement in the mineral matrix. The organic pigments in red cor…
Enabling environments for equity, access and quality education post-2015 : Lessons from South Africa and Tanzania
2016
In this paper we seek to contribute to the post-2015 education agenda by shifting the focus from considerations of what education goals and targets should be to a people-centred exploration of enabling environments, within and beyond education, for equity, access and quality. Theoretically, the paper draws on the capabilities approach. Empirically, we present data from two independent qualitative studies conducted in South Africa (n = 40) and Tanzania (n = 10) with university students who accessed higher education despite trends of low participation for their social class and/or gender. The paper highlights the importance of taking account of both instrumental and intrinsic values of educat…
Examining consumers' intention, behavior, and beliefs in mobile banking adoption and continuous usage
2016
Changing consumer behavior continues to have a profound impact on digital banking adoption and prolonged usage in developed and emerging markets. Several factors influence the consumer decision journey when choosing any specific digital channel or combination of channels. Among a variety of digital banking channels, this dissertation research seeks to contribute to the mobile banking (m-banking) literature by examining consumer behavior in m-banking services as well as technology (application) adoption and continuous usage, especially after considering the fact that financial service institutions have entered a time when offering mobile-based services is no longer a novelty but a necessity.…
Isolement et caractérisation de saponosides extraits de deux plantes médicinales : Cyclamen africanum, Zygophyllum cornutum et évalution de leur acti…

The appearance of several diseases, such as cancer, diabetes, high blood pressure and spread of infections mutagenic virus type can be linked to the quality and lifestyle that we lead today. Indeed, several studies on the factors triggering these so-called "morbid" long-or short-term illnesses are related to stress and quality of food consumed, whether of plant and animal origin. These diseases are becoming a common occurrence, they affect different races and all classes of society. According ethnobotanical research, naturally occurring substances, allowed civilizations to survive deadly diseases. For example, we thus find references to periods of malarial fever in China and one of the symp…
Construction of migration project and reasons for emigrating in sub-Saharan African francophone population. An intercontinental study Europe-Africa
2012
Este estudio da cuenta de las razones de los ciudadanos de África subsahariana francófona para establecerse en Europa, y particularmente en Francia, mediante la creación de un marco comprensivo innovador que vincula tres ejes temáticos: la motivación, las migraciones, y África y sus relaciones con Europa. 155 participantes en ambos continentes respondieron a un cuestionario sobre su proyecto migratorio real o posible. Los resultados plantean un plano general de acercamiento a los imaginarios y la realidad de los migrantes en el contexto francés, marcado por la reflexión sobre la identidad nacional, los controles migratorios, un clima político reticente a la migración y un tejido social cara…
Determinants of the interannual relationships between remote sensed photosynthetic activity and rainfall in tropical Africa
2007
International audience; The response of photosynthetic activity to interannual rainfall variations in Africa South of the Sahara is examined using 20 years (1981-2000) of Normalised Difference Vegetation Index (NDVI) AVHRR data. Linear correlations and regressions were computed between annual NDVI and annual rainfall at a 0.5° latitude/longitude resolution, based on two gridded precipitation datasets (Climate Prediction Center Merged Analysis of Precipitation [CMAP] and Climatic Research Unit [CRU]). The spatial patterns were then examined to detect how they relate to the mean annual rainfall amounts, land-cover types as from the Global Land Cover 2000 data set, soil properties and soil typ…
Integración y transformación económica en África: potencial y limitaciones del Área de Libre Comercio Continental Africana
2021
In March 2018, the African Union gave way to the establishment of the African Continental Free Trade Area, the largest area of economic integration in the world by number of countries involved. As of June 2020, 54 out of 55 African Union member countries have already signed the agreement, thus showing an almost complete unanimity on this topic. AfCFTA comes up when industrialisation strategies and economic transformation in Africa seem to have taken over orthodox structural adjustment and post-adjustment approaches. AfCFTA aims to increase the scarce intra-African trade, boost economic transformation, create the regional value chains and help African firms to join the global value chains. I…
Regional Economic Integration in the Southern African Development Community (SADC): Analysing the Dynamics and Performance
2020
This article analyses the dynamics and performance of regional economic integration in the Southern African Development Community (SADC). It proposes an innovative theoretical approach to the analysis of regionalism that refers to cooperation theory and takes the impact of external actors explicitly into account. The motivation for this research stems from the observation of a new wave of regionalism in the Global South. Many of these new or reformed regional integration organisations (RIOs) comprise of developing countries, particularly in Africa. In contrast to expectations of most mainstream integration theories, new regionalisms in the Southern Hemisphere have come into existence and sh…
