Transfert d’auctoritates du sémantique à l’indiciaire au XVIIe siècle : Gassendi et Hobbes
Cygne Noir, 2018 L’histoire de la pensée sémiotique se caractérise par une oscillation entre définition large et définition étroite de son objet. Au Moyen Âge, la définition augustinienne du signe est jugée trop étroite, car elle ne concerne que le signe sensible.

Overcoming Natural Resource Constraints Through R&D [PDF]
We study the optimal policies of research and development in the context of a resource-exploiting economy. We distinguish two cases: non-renewable resources and renewable resources.

IRPF90: a programming environment for high performance computing [PDF]
, 2009 IRPF90 is a Fortran programming environment which helps the development of large Fortran codes. In Fortran programs, the programmer has to focus on the order of the instructions: before using a variable, the programmer has to be sure that it has already ...

Econometrics, 2019 It is customary to assume that an indicator of a latent variable is driven by the latent variable and some random noise. In contrast, a background indicator is also systematically influenced by variables outside the structural model of interest. Background indicators deserve attention because in empirical work they are difficult to distinguish from ...

An integrated approach to balance freshwater connectivity restoration and invasion risk
Conservation Biology, EarlyView.Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...

Designing a Performance Indicator to Economize on Monopoly Subsidy [PDF]
We provide a continuum of subsidy rules based on a performance indicator that induce a monopoly to choose the socially optimal production level. These subsidy rules result in a reduction of the amount of subsidy paid to the monopolist compared to the ...

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, EarlyView.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities
Conservation Biology, EarlyView.Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, EarlyView.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.
