Discontinuity in natural language is characterized by the linear disruption of a continuous string of linguistic expressions forming a constituent. While dependency relations in Dependency Grammar (DG) can capture discontinuity well, phrase-structure-based approaches such as Phrase Structure Grammar (PSG) face difficulty in accommodating discontinuity. Categorial Grammar (CG) has correspondences with PSG, although it can handle discontinuity, if equipped with wrapping operations. Given the existing literature on discontinuity in natural language, it appears that constituency relations of PSG, dependency relations of DG and functor-argument relations of CG are distinct and independent. Here, we argue for a unified representation achieved by taking into account fundamental representational principles of PSG, DG and CG. For simplicity, we show this by considering an embedded clause from Wan, spoken in Ivory Coast, as an illustrative case. The paper then attempts to explain, based on available empirical pieces of evidence, the plausible connections between the unified representation and the neurocognitive representation of continuity and discontinuity in natural language.

Earth – satellite microwave links such as TV-SAT can help for rainfall monitoring and could be a complement or an alternative to ground-based weather radars, rain gauges or satellites dedicated to Earth observation. Rain induced attenuation which is harmful for telecommunication is exploited here as an opportunistic way to estimate rain rate along the path link. This technique makes it possible to obtain rain measurements at a fine temporal resolution (a few tens of seconds) and with a spatial resolution of few kilometers, which is a good compromise for human activities such as civil security (watershed monitoring, flash flood), agriculture or transport. Among the advantages of this technique, one can note the low cost of the hardware used (which can be commercial) as well as that of its maintenance on site. However, measured attenuation does not directly provide rain intensity and some parameters have to be estimated. Among these, it is necessary to take into account the contribution of the natural radiation of the atmosphere. In this paper, we detail a theoretical framework allowing to estimate rainfall from the measurements of a low-cost sensor operating simultaneously over two parts of the Ku-frenquency band. Then this framework is assessed in a densely instrumented area in south of France, where it is shown that very good results are obtained when compared to rain gauges measurements, both in terms of overall rain accumulation and in terms of rainfall rate distribution. Then we apply this dual channel method in Ivory Coast, in the metropolitan area of Abidjan, where such an approach is very promising. It is shown that this technique when compared to rain gauge measurements give results far better than a single-channel naive approach neglecting natural radiation of atmosphere, but that there are still significant errors in the rain assessment, leading to a persistent underestimation of rain accumulation. Finally we discuss various effects that could lead to this remaining underestimation, opening the door to further studies. [ABSTRACT FROM AUTHOR]

In this paper, we develop a three-period gender-based Overlapping Generations (OLG) model of economic growth for Côte d'Ivoire in which life expectancy is endogenized and the rate of change of the poverty rate is linked to the growth rate of output per capita. We then calibrate the model using the country-specific calibration data to illustrate the role of public policies in the model, and its implications for long-term growth, gender equality, and poverty in Côte d'Ivoire. To this end, we discuss three sets of quantitative experiments: broad-based development policies (increase in education spending and infrastructure investment, and governance reform), gender-based policies (reduction in gender bias in the market place, increase in women's bargaining power, and reduction in family bias against girls' education), and a composite reform program (combination of pro-growth, pro-gender policies). Overall, our findings suggest that Côte d'Ivoire could achieve better growth and poverty outcomes if the country could implement a composite reform program that includes comprehensive development and gender-based policies.

This paper analyzes changes in agricultural productivity gender gaps in Côte d'Ivoire between 2008 and 2016 using decomposition methods. The analysis finds that the gender gap went from 40% in food crops and 17% in exports crops in 2008, to 19% in food crops and a statistical zero in export crops in 2016. The overall gender gap decreased by 15 percentage points over this period, and is statistically insignificant in 2016 once accounting for whether households farm export crops. Moreover, our results show that while some drivers of the gender gap remain stable across the decade (including total land cultivated, and pesticide and fertilizer use), others change their contribution (number of plots, crop choice and household labor). Despite substantial improvements, female‐headed households in the bottom half of the distribution remain disadvantaged. Our results indicate that strengthening women's access to agricultural labor and adoption of export crops are policy priorities to reach gender parity. [ABSTRACT FROM AUTHOR]

This paper examines the relationship between child labour and educational attainment and explores the distinction between harmful and non-harmful agricultural cocoa work. We conduct a secondary analysis of data on 3,338 children who reported attending school in 2018 across cocoa growing regions of Ghana and Côte d’Ivoire. To address differences between harmful and non-harmful child labour, we differentiated work completed by a child by hazardous activity engagement. These groups of child labour were then modelled against educational attainment, defined by a whether or not the child needed to repeat a class. We then conducted mediation analysis to assess whether injury mediates this relationship. Our results show that hazardous child labour increases the odds of repeating a class and work-related injury compared to non-hazardous labour. The effect of hazardous child labour on academic attainment was also found to be mediated by work-related injuries by 14%. Educational attainment is associated with hazardous labour activities and the odds of injury and not the act of participation in agricultural labour alone. Programmes based on strong measures of harmful work will foster better protection for children who are most at risk and may inform global debates around the benefits versus the risks of child labour.

• Modern inputs and mechanization can raise smallholder labor productivity and broker the structural transformation. • Intensification increases land and labor productivity, especially when agro-chemicals and mechanized land preparation are combined. • Returns to labor double to triple, inducing specialization and greater market orientation as well as greater food security. • Labor in agriculture becomes more waged, and gender balance remains the same. • Agricultural intensification is a key pathway towards rural transformation. Modern inputs and mechanization are promoted across Africa to raise smallholder labor productivity and broker the structural transformation. Yet, adoption has remained low and the implications for returns to labor and labor allocation remain poorly understood. This paper explores the effects of different intensification packages on farm performance, market orientation, and food security using data from lowland rice farmers in Côte d'Ivoire. Employing a multinomial treatment effect model, the findings reveal that intensification increases land and labor productivity, especially when agro-chemicals and mechanized land preparation are combined. Returns to labor more than triple, inducing greater market orientation as well as greater food security. This opens opportunities to productively release agricultural labor for other activities (on and off the farm). Labor in rice production becomes more waged and slightly more male, but child labor input does not decrease. The findings call for greater attention to labor productivity and confirm that agricultural intensification can pay and enhance rural transformation. [ABSTRACT FROM AUTHOR]
