Maximum of Branching Brownian Motion among mild obstacles

We study the height of the maximal particle at time $t$ of a one dimensional branching Brownian motion with a space-dependent branching rate. The branching rate is set to zero in finitely many intervals (obstacles) of order $t$. We obtain almost sure asymptotics of the first order of the maximum, describe the path of a particle reaching this height and describe its dependence on the size and location of the obstacles.Comment: 36 pages, 4 figure

Reconversion à l’agriculture biologique

Les questions liées à la commercialisation jouent un rôle central dans le processus de décision relatif à la reconversion: les canaux de distribution existants peuvent-ils rester en place? Ou de nouvelles stratégies de vente s’avèrent-elles nécessaires? Cette fiche technique livre des informations utiles sur la commercialisation des produits de reconversion et des produits bio, et renvoie à d’autres sources d’information

Life Satisfaction and mobility: Their associations with career attitudes, and health-related factors among postgraduates having studied in universities intra EU and outside EU

Background. University postgraduates’ mobility towards, and outside the EU is continuously increasing, creating a competitive context in which maintaining a high life satisfaction (LS) is a public health challenge. However, the relationship between LS and its determinants among this population are under-documented. Our aims were to measure LS indicators of mobile postgraduates (Intra EU: Who pursue part of their studies in Europe; Outside EU: Who study outside of Europe) versus non-mobile (pursue their studies in Luxembourg), and to analyze the associations between LS and career attitudes, socioeconomic characteristics, and health-related factors for each group. Method. Six hundred and sixty-four (644) students obtained financial aid from the Luxembourgish government independent of their family’s socioeconomic situation. Contacted by post, they completed an online questionnaire. Analyses included a multiple linear regression model in which only significant relationships (p < 0.05) were used. Results.Three groups were created: Mobile intra EU (n = 381), mobile outside EU (n = 43) and non-mobile (n = 66) postgraduates. Health satisfaction was positively linked to LS, in all groups. Among the mobile outside EU group, majority (63.2%) were men and 57.9% did not live alone - health was the only determinant which contributed to their LS. Among the mobile intra EU, majority (57.8%) were women, and 64.3% not living alone. Autonomy and career adaptability attitudes were positively associated with their LS (b: 0.210 and 0.119, respectively), whereas the worry factor was negatively (b: − 0.153 and -0.159) associated. The non-mobile, were the oldest of the three groups. Majority (51.6%) were women, and 93.7% did not live alone. Career optimism and planning attitudes were positively correlated to their LS (regression parameter estimates (b: 0.400 and 0.212, respectively). Conclusions.Attention should be devoted to the LS of local and cosmopolitan students, as it seems to be a relevant health indicator. Overall, the farther the mobility was, the higher the postgraduates’ general LS (8.5/10) was; this indicator was higher than the LS indicator for the age group 25–34 years 7.53/10 (EU-28, in 2013). University’ services could promote the development of career projects and the promotion of health to enhance postgraduates’ LS. University policy makers need to ensure this for all students
