Vaccination control programs for multiple livestock host species: an age-stratified, seasonal transmission model for brucellosis control in endemic settings

Brucella melitensis causes production losses in ruminants and febrile disease in humans in Africa, Central Asia, the Middle East and elsewhere. Although traditionally understood to affect primarily sheep and goats, it is also the predominant Brucella species that affects cows in some endemic areas. Despite this, no licensed vaccine is available specifically for use against B. melitensis in cows. The mainstay of most control programs is vaccination of sheep and goats with a live vaccine, Rev-1. The aim of this study was to investigate how critical vaccination of cows might be, in order to control B. melitensis on a mixed sheep-and-cattle farm

Edith Stein et Erich Przywara : la réconciliation du noétique et de l’ontique

Cet article tente de montrer la parenté intellectuelle entre Edith Stein et Erich Przywara. Les deux montrent en effet que ni une philosophie de l’être ni une philosophie de la connaissance ne peuvent s’accomplir absolument. Si Przywara élabore une synthèse métaphysique complexe en se basant sur une analyse de l’histoire de la philosophie, Stein compte perfectionner la phénoménologie en lui montrant le chemin de l’être.The present article tries to bring out an intellectual kinship between Edith Stein and Erich Przywara. For they both prove that neither can a philosophy of being nor a philosophy of knowledge be accomplished absolutely. While Przywara elaborates a complex metaphysical synthesis based on an analysis of the history of philosophy, Stein attempts to perfect phenomenology by showing it the road to being
