The Relationship

This paper explores the issues of representativeness and participation in the collective processes involved in the elaboration of the geographical indications (GI) specifications and the governance of the GI initiatives. The objective is to understand the relationship among collective dynamics, representativeness of relevant stakeholders, and the legal frameworks for the protection of GIs. Using a qualitative methodology based on an analysis of six case studies in France and Vietnam, we show the role of the law in shaping the different ways of understanding and implementing the concept of representativeness in the French producer-led and the Vietnamese state-driven approaches to GI protection. In France, the GI specifications result from negotiations among all legitimate stakeholders, which may prove long, complex, and lead to standards that can continue to be challenged after the GI registration. We also argue that the rules for the representation of all GI users in the decision-making processes do not necessarily lead to fairness. In Vietnam, local stakeholders usually have a consultative role under the authority of the State, resulting in their little understanding and low use of the GI. Their empowerment is further hindered by the involvement of state authorities in the management of the producers’ associations. We conclude by discussing in-between solutions to promote the producers’ representation and participation.

Navigation Strategies

AbstractAs compared to the well explored problem of how to steer a macroscopic agent, like an airplane or a moon lander, to optimally reach a target, optimal navigation strategies for microswimmers experiencing hydrodynamic interactions with walls and obstacles are far-less understood. Here, we systematically explore this problem and show that the characteristic microswimmer-flow-field crucially influences the navigation strategy required to reach a target in the fastest way. The resulting optimal trajectories can have remarkable and non-intuitive shapes, which qualitatively differ from those of dry active particles or motile macroagents. Our results provide insights into the role of hydrodynamics and fluctuations on optimal navigation at the microscale, and suggest that microorganisms might have survival advantages when strategically controlling their distance to remote walls.
