Development of a system for man-machine experimentation

Creator:: Asselbergs, Christophe K. J.
Abstract:: Adapting man, as an organic link, to closed loop control systems, is increasingly presenting problems to designers of systems of any nature. Performance of the human in the systems is dependent upon a multitude of recognized factors, and many as yet unknown factors and variables. In order to investigate the...

Assessing Vulnerability to Poverty in Fishing Communities

Creator:: Béné, Christophe
Abstract:: In this paper we develop an index of economic vulnerability which we use conjointly with a more conventional measure of income poverty to explore the different dimensions of poverty (transient, chronic, vulnerability) that affect fishing communities in developing countries. We illustrate the potential uses of this method with cross-sectoral data...

Contribution of Fishing to Households' Economy - Evidence From Fisher-Farmer Communities in Congo

Creator:: Béné, Christophe
Abstract:: Small-scale fisheries in developing countries have often been perceived as a low-productivity, backward informal sector. As a result they are rarely considered as a possible entry point in poverty reduction and rural development planning. Data collected in Democratic Republic of Congo show that this perception may not reflect the empirical...

Viable coalitions in open access

Creator:: Doyen, Luc and Pereau, Jean-Christophe
Abstract:: This article gives insights on the complex balance between coalitions structure, resource state or dynamics and agents’ heterogeneity to avoid bio-economic collapses. A model bringing together coalition games and a viability approach is proposed to focus on the compatibility between bio-economic constraints and an exploited common stock dynamics. It is...

Global Change in African Fish Trade: Engine of Development or Threat to Local Food Security?

Creator:: Béné, Christophe and Lawton, Rebecca
Abstract:: Today fish is the most traded food commodity in the World. This situation is not without generating potential issues. On the one hand, fish trade is said to support economic growth processes in developing countries by providing an important source of cash revenue. On the other hand, fish trade is...

Investigating the dynamic relationships between wild shrimp and cultured shrimp prices

Creator:: Cadren, Muriel, Béne, Christophe, and Lantz, Frédéric
Abstract:: The arrival in the 1980s of cultured shrimp has induced large changes on the World shrimp market. In this new environment, the French Guyana fishery production now competes strongly with some of these farm-produced shrimp. Consequently, this fishery has experienced serious export problems during the last decade. This paper is...

Bordered pit structure and function determine spatial patterns of air-seeding thresholds in xylem of Doulglas-fir (Pseudotsuga menziesii; Pinaceae) trees

Creator:: Domec, Jean-Christophe, Lachenbruch, Barbara, and Meinzer, Frederick C.
Abstract:: The air‐seeding hypothesis predicts that xylem embolism resistance is linked directly to bordered pit functioning. We tested this prediction in trunks, roots, and branches at different vertical and radial locations in young and old trees of Pseudotsuga menziesii. Dimensions of bordered pits were measured from light and scanning electron micrographs,...

Safety factors for xylem failure by implosion and air-seeding within roots, trunks and branches of young and old conifer trees

Creator:: Domec, Jean-Christophe, Warren, Jeffrey M., Meinzer, Frederick C., and Lachenbruch, Barbara
Abstract:: The cohesion-tension theory of water transport states that hydrogen bonds hold water molecules together and that they are pulled through the xylem under tension. This tension could cause transport failure in at least two ways: collapse of the conduit walls (implosion), or rupture of the water column through air-seeding. The...

Evaluating Livelihood Strategies and the Role of Inland Fisheries in Rural Development and Poverty Alleviation: The Case of the Yaéré Floodplain in North Cameroon

Creator:: Béné, Christophe, Mindjimba, Koané, Belal, Emma, and Jolley, Tom
Abstract:: It is usually assumed that most, if not all, small scale fishing communities, particularly in tropical countries, represents the poorest and most disadvantaged part of rural societies. As a result, these populations have been targeted for poverty alleviation by fisheries development programmes since the early 60's. Unfortunately many of these...

Dynamics of water transport and storage in conifers studied with deuterium and heat tracing techniques

Creator:: Meinzer, Frederick C., Brooks, J. R., Domec, Jean-Christophe, Gartner, Barbara L., Warren, J. M., Woodruff, D. R., Bible, K., and Shaw, D. C.
Abstract:: The volume and complexity of their vascular systems make the dynamics of long‐distance water transport in large trees difficult to study. We used heat and deuterated water (D₂O) as tracers to characterize whole‐tree water transport and storage properties in individual trees belonging to the coniferous species Pseudotsuga menziesii (Mirb.) Franco...
