Exposer l’Ethnoécologie au Musée de l’Homme by Serge Bahuchet, Valérie Kozlowski, Marie Merlin, Agnès Parent

“…In this pluridisciplinary itinerary, ethnoecology is inserted in little touches into several showcases: representation of nature (1001 ways of thinking the world), domestication and diversification of plants (with example of chilies), bees symbolism, portraits and contemporary ways of life (lifestyles with different impacts) and agrobiodiversity (with the example of maize in Mexico).…”

Sexualitet, samtycke och relationer i grundskolans bildämne by Elisabeth Lisa Öhman

“…More specifically, it explores how phenomena such as identity, sexuality, and gender are material—discursively produced during 15–16-year-old students’ work with photographic portraits in Arts education in Grade 9. Using Karen Barad’s concept of space-time-matter in the analysis shows how subject-didactic opportunities and challenges reformulate the ideas about what sexuality education can be. …”

La constitution de ressources urbaines dans les parcours de familles migrantes à Mexico by Aurélia Michel

“…This paper aims to characterize urban resources in the context of Mexico City. Through six portraits of six women which migrated to Naucalpan, an industrial suburb of Mexico city, we expect to show how migrant families face the challenge of settling in the metropolis and of building sustainable access to the main resources. …”

Bifurcation Analysis and Chaos Control in a Discrete-Time Parasite-Host Model by Xueli Chen, Lishun Ren

“…The numerical simulations not only illustrate the consistence with the theoretical analysis, but also exhibit other complex dynamical behaviors, such as bifurcation diagrams, Maximum Lyapunov exponents, and phase portraits. More specifically, when the integral step size is chosen as a bifurcation parameter, this paper presents the finding of period orbits, attracting invariant cycles and chaotic attractors of the discrete-time parasite-host system. …”
