Avant-propos: Informer sous algorithmes

Le développement des médias numériques, parce qu’il bouleverse les codes et déstabilise les normes professionnelles et les modèles économiques, remet au premier plan dans le monde de l’information des enjeux d’écriture, de format, et donc de poétique, qui ont joué un rôle prépondérant avant que le journalisme ne s’autonomise largement de la littérature. Au tournant des années 2020, l’écriture de l’information se trouve aux prises avec une nouvelle contrainte : le pouvoir des algorithmes. Ce ..

Facing homelessness

In facing homelessness we face the other, and in facing the other, we face ourselves. This book contributes to an emerging body of knowledge on street homelessness in the South African context. It is meant for researchers and scholars who are committed to finding solutions for street homelessness. It offers conceptual frameworks and practical guidelines for a liberative and transformative response to homelessness. It brings together authors from a wide range of disciplines, fusing the rigour of researchers, the vision of activists and the lived experience of practitioners. In this volume, the causes of street homelessness in South Africa today, and its different faces, are traced. It critiques singular solutions, and interrogates the political, institutional and moral failures that contribute to the systemic exclusion of homeless persons and other vulnerable populations from society. It proposes rights-based interventions as part of a radical re-imagination of how street homelessness can be ended, one person and one neighbourhood at a time. The analysis by the authors steer in the direction of new ways of doing and being that could demonstrate concrete, viable and sustainable alternatives to the exclusionary realities faced by homeless persons. It argues for solution-based approaches, aimed at radical forms of social inclusion and achieved through broad-based and creative collaborations by all spheres of society. In the face and presence of street homelessness – as one expression of urban vulnerability and deep socio-economic inequality – society is confronted with a clear political, institutional, moral and personal obligation. This volume calls for a reclamation of community in its most inclusionary, life-affirming and interdependent sense, asserting that we truly are well because of others, and we are unwell if others are. It is a call to reclaim our common humanity in the context of inclusive communities where all are equally welcome and bestowed with dignity and honour

The HARPS search for southern extra-solar planets XVIII. An Earth-mass planet in the GJ 581 planetary system

The GJ 581 planetary system was already known to harbour three planets, including two super-Earths planets which straddle its habitable zone. We report here the detection of an additional planet -- GJ 581e -- with a minimum mass of 1.9 M_earth. With a period of 3.15 days, it is the innermost planet of the system and has a ~5% transit probability. We also correct our previous confusion of the orbital period of GJ 581d (the outermost planet) with a one-year alias, thanks to an extended time span and many more measurements. The revised period is 66.8 days, and locates the semi-major axis inside the habitable zone of the low mass star. The dynamical stability of the 4-planet system imposes an upper bound on the orbital plane inclination. The planets cannot be more massive than approximately 1.6 times their minimum mass.Comment: 9 pages, A&A Accepte

The Rosa genome provides new insights into the domestication of modern roses

Roses have high cultural and economic importance as ornamental plants and in the perfume industry. We report the rose whole-genome sequencing and assembly and resequencing of major genotypes that contributed to rose domestication. We generated a homozygous genotype from a heterozygous diploid modern rose progenitor, Rosa chinensis ‘Old Blush’. Using single-molecule real-time sequencing and a meta-assembly approach, we obtained one of the most comprehensive plant genomes to date. Diversity analyses highlighted the mosaic origin of ‘La France’, one of the first hybrids combining the growth vigor of European species and the recurrent blooming of Chinese species. Genomic segments of Chinese ancestry identified new candidate genes for recurrent blooming. Reconstructing regulatory and secondary metabolism pathways allowed us to propose a model of interconnected regulation of scent and flower color. This genome provides a foundation for understanding the mechanisms governing rose traits and should accelerate improvement in roses, Rosaceae and ornamentals
