Three trials have been set up in Côte d’Ivoire to analyse the growth of six-year-old microcuttings produced from seedlings, 45-month-old somatic embryos of PB 260 and PR 107 and 31-month-old microcuttings of IRCA 18. The results show that Hevea in vitro plantlets produced by somatic embryogenesis or microcutting consistently grow as well as if not better than conventional budded plants. The dif...

Guébie, a Kru language spoken in Côte d’Ivoire, is currently doubly classified within Eastern Kru according to Ethnologue (Lewis et al. 2013). It is listed as a dialect of two distinct subgroups, Bété and Dida. This double classification is clearly problematic, and this paper provides the initial work towards addressing the correct classification of the language. Here I compare the phonological...

This study leverages mobile phone data to analyze mobility patterns in developing countries, especially in comparison to more developed countries. Developing regions, such as the Ivory Coast, are marked by a number of factors that may influence mobility, such as less infrastructural coverage and maturity, less economic resources and stability, and in some cases, more cultural and language-based...

This paper proposes a microeconomic decomposition of the evolution of income inequality in Côte d’Ivoire in the 1990s, allowing to disentangle the simultaneous contributions of four types of phenomena to the evolution of the distribution of income: a change in the remuneration rates of the observed and unobserved earnings determinants, a change in the occupational preferences, and a change in t...

Fires, lights at night and mobile phone activity have been separately used as proxy indicators of human activity with high potential for measuring human development. In this preliminary report, we develop some tools and methodologies to identify and visualize relations among remote sensing datasets containing fires and night lights information with mobile phone activity in Cote D’Ivoire from De...

We investigate the relation between performances of speech and of song in the awosi dirge genre of Anyi (Kwa, Côte d’Ivoire). The relation between speech and song prosody has not been extensively studied, in terms of either structure or performance variation. We address phonetic issues of pitch height, tonal prominence, downtrends of speech in relation to melodic trends in song, and the phonolo...

The article outlines how we have identified the cities, city population, strength of social ties among cities, urban mobility in the largest city of Abidjan, and locations of residential and work areas. To deal with otherwise inadequate information contained in the D4D call detail records we introduced some daring assumptions and invented approximation techniques. Although further investigation...

In this paper I argue that Nouchi, a relatively young Ivoirian contact variety, is and should be treated as a full-fledged language distinct from French and its other source languages. Nouchi, an emerging language spoken in Côte d’Ivoire since that late 1970’s (Ayewa 2005), has been treated in the literature as a slang vocabulary or an urban youth dialect of French. Though Nouchi began as a lin...

The Western clawed frog, Xenopus tropicalis, is a highly promising model amphibian, especially in developmental and physiological research, and as a tool for understanding disease. It was originally found in the West African rainforest belt, and was introduced to the research community in the 1990s. The major strains thus far known include the Nigerian and Ivory Coast strains. However, due to i...

This paper revisits the contested issue of the impact of agricultural extension on farm productivity. Often studies in this …eld su¤er from a bias either due to self-selection of the best farmers for the extension services or to endogenous placement of the programme. The panel dataset collected by ANADERand the nature of the extension programme put into operation in Côte d’Ivoire between 1997 a...
