Le paysage nocturne de montagne, nouvelle identité visuelle et outil d’action collective pour des territoires en transitions ?

2017

International audience; Les « paysages nocturnes » sont de plus en plus mobilisés comme biens environnementaux à part entière par les territoires ruraux de faibles densités. À travers la « qualité de la nuit » et « l’accès au ciel étoilé », c’est bien la dimension nocturne des aménités paysagères qui est désormais placée au cœur de plusieurs politiques de protection de la nature à travers le monde (Charlier & Bourgeois, 2013 ; Bénos et al., 2015). Ces politiques sont souvent accompagnées de processus de mise en réserve et de labellisation de territoires garants d’un accès privilégié à la « nuit noire » et aux « ressources environnementales nocturnes », loin des nuisances et pollutions lumin…

Le passage de Haies: De la réalité sportive en heptathlon à la réalité subjective d'Emma

2006

The major dimension of this article is to point out the importance of psychological follow-up with sporting teenagers. Emma's example illustrates the inherent transitions from this period of age in the specific context of the high level sport. For Emma, the passage of hurdle becomes the metaphor of its psychical conflict. The counter performance which appears in the passage of hurdle announces its ambivalence with regard to its personal history within realities of sport cultures. This making sense of the sporting problems within the framework of the psychological follow-up can help to exceed this difficulty of passage and to support its engagement like subject of its own desire on the way o…

Analysis of ecological shifts in the two‐age structured population model with Allee effect and environmental noise

2020

We study noise-induced transformations in the two-age structured population model with the Allee effect and environmental fluctuations. In this bistable model, ecological shifts are associated mathematically with random transitions between basins of coexisting attractors. The following phenomena are revealed and studied: (i) noise-induced extinction, (ii) stochastic regeneration, and (iii) excitement of random mixed-mode oscillations. Constructive abilities of the analytical method of confidence domains are demonstrated in the parametric study of these phenomena.

Legumes in 21st century Europe: present and future importance in agri-food systems? New challenges for reseach.

2013

Intensification of agriculture since 1950 has globally led to the decline of grain legume crops, which currently represent less than 3 % of arable crops in France and Europe. Nevertheless, legumes have several major assets (i) as plant proteins for animal feed and human food and (ii) as plants fixing atmospheric N2 and thereby saving nitrogen inputs in cropping systems, and (iii) as diversification crops. The analysis of forage and grain legume producing systems in France showed that the dominant system results in a lock-in of the different factors limiting legume insertion into the current systems. But legumes could have a major role to play in the agroecological transition towards more su…

Microscopic calculation of the $\beta^-$ decays of $^{151}$Sm, $^{171}$Tm, and $^{210}$Pb with implications to detection of the cosmic neutrino backg…

The electron spectral shapes corresponding to the low-$Q$ $\beta^-$-decay transitions $^{151}$Sm$(5/2^-_{\rm g.s.})\to\,^{151}\textrm{Eu}(5/2^+_{\rm g.s.})$, $^{151}$Sm$(5/2^-_{\rm g.s.})\to\,^{151}\textrm{Eu}(7/2^+_{1})$, $^{171}$Tm$(1/2^+_{\rm g.s.})\to\,^{171}\textrm{Yb}(1/2^-_{\rm g.s.})$, $^{171}$Tm$(1/2^+_{\rm g.s.})\to\,^{171}\textrm{Yb}(3/2^-_{1})$, $^{210}\textrm{Pb}(0^+_{\rm g.s.})\to\,^{210}\textrm{Bi}(1^-_{\rm g.s.})$, and $^{210}\textrm{Pb}(0^+_{\rm g.s.})\to\,^{210}\textrm{Bi}(0^-_{1})$ have been computed using beta-decay theory with several refinements for these first-forbidden nonunique (ff-nu) $\beta^-$ transitions. These ff-nu $\beta^-$ transitions have non-trivial electro…

Precise measurements of half-lives and branching ratios for the ββ mirror transitions in the decay of 23Mg and 27Si

2017

Half-lives and branching ratios for the two mirror ββ decays of 23Mg and 27Si have been measured at the University of Jyväskylä with the IGISOL facility. The results obtained, T1/2=11.303(3)T1/2=11.303(3) s and T1/2=4.112(2)T1/2=4.112(2) s for the half-lives of 23Mg and 27Si , respectively, are 7 and 8 times more precise than the averages of previous measurements. The values obtained for the super-allowed branching ratios of 23Mg and 27Si are B.R.=92.18(8)%B.R.=92.18(8)% and B.R.=99.74(2)%B.R.=99.74(2)% , respectively. The result for 23Mg is three times more precise than the average of the previous measurements, while for 27Si the precision has not been improved, the average of the previous…

Using Contextual Action Theory for conceptualization and research on adolescent development

2019

Recently, scholars’ calls for psychology to move beyond traditional ways of conceptualizing and researching human behaviour have increased. Contextual Action Theory (CAT) is a conceptual, methodological, and practical framework that is consistent with these calls. In CAT action is conceptualized as a complex, dynamic, and multidimensional system that can be comprehended from multiple levels of organization and from multiple perspectives. The Action-Project Method (A-PM) is the research method that emerged from CAT. It is a qualitative, naturalistic, process-oriented, longitudinal methodology that has been used to study joint, goal-directed actions and projects. The focus of data gathering a…

Demographic inequalities as determinants and consequences of the COVID-19 pandemic in Latvia

2021

Since early March 2020 Latvia is fighting the COVID-19 pandemic. Lessons learned from this crisis will be instrumental in shaping future public health policy. Any policy response to the pandemic must be tailored to the particular risks within population in order to avoid the unnecessary social and economic damage on a national and international scale. Available literature on the topic highlights region-specific demographic factors associated with elevated population vulnerability to the effects of the COVID-19 pandemic. This study aims to ascertain the role of a pre-existing demographic inequalities in Latvia in the onset and progression of COVID-19 pandemic and lay groundwork for projectin…
