Eine Uni - ein Buch: Das zweite Buch!

Dieses Buch stellt gleichsam die Ernte der einjährigen universitätsweiten Auseinandersetzung mit dem Buch «Erfindet euch neu! Eine Liebeserklärung an die vernetzte Generation» von Michel Serres dar. Auslöser war der Gewinn des Wettbewerbs «Eine Uni – ein Buch», der vom Stifterverband und der Klaus Tschira Stiftung in Kooperation mit DIE ZEIT ausgeschrieben worden ist. Nach einer kurzen Einführung in den Wettbewerbsbeitrag der Stiftung Universität Hildesheim erfolgen Überlegungen über Sprache und Literatur im digitalen Zeitalter sowie zwei ausführliche Auseinandersetzungen aus soziologischer und politikwissenschaftlicher Perspektive mit dem Buch des französischen Philosophen über die kleinen Däumlinge. Großen Raum nehmen sodann die mannigfaltigen Antworten von Studierenden, Lehrenden und Mitarbeiter_innen im Rahmen von Einzelinterviews zu den drei Leitfragen ein: 1. Was verstehen wir unter Wissen? 2. Wie ist unsere digitale Wahrnehmung? 3. Wie tickt unsere Zeit? Ergänzt werden diese Stimmen durch den Abdruck verschiedener Screenshots aus den digitalen Lesegruppen und Leseforen. Ein Essay über soziales Lesen und Schreiben unter den Bedingungen der digitalen Transformation rundet diesen Band ab

The Kodaira problem for K\"ahler spaces with vanishing first Chern class

Let $X$ be a normal compact K\"ahler space with klt singularities and torsion canonical bundle. We show that $X$ admits arbitrarily small deformations that are projective varieties if its locally trivial deformation space is smooth. We then prove that this unobstructedness assumption holds in at least three cases: if $X$ has toroidal singularities, if $X$ has finite quotient singularities, and if the second cohomology group of its tangent sheaf vanishes.Comment: Final version, to appear in Forum of Mathematics, Sigm

Introduction—Up, down, round and round: Verticalities in the history of science

History of science's spatial turn has focused on the horizontal dimension, leaving the role of the vertical mostly unexplored as both a condition and object of scientific knowledge production. This special issue seeks to contribute to a burgeoning discussion on the role of verticality in modern sciences, building upon a wider interdisciplinary debate about the importance of the vertical and the volumetric in the making of modern lifeworlds. In this essay and in the contributions that follow, verticality appears as a condition of knowledge production—a set of movements and mobilities, technical challenges, political negotiations, and bodily hardships—and an object of scientific inquiry, requiring new techniques of mapping and visualisation and generative of new insights into physical processes and temporal change. By foregrounding the vertical, historians of science can gain new insights and tell new stories about how science is done in the field, the observatory, and the laboratory, and about how those sciences have helped build a modern, three‐dimensional world

Bovine polledness

The persistent horns are an important trait of speciation for the family Bovidae with complex morphogenesis taking place briefly after birth. The polledness is highly favourable in modern cattle breeding systems but serious animal welfare issues urge for a solution in the production of hornless cattle other than dehorning. Although the dominant inhibition of horn morphogenesis was discovered more than 70 years ago, and the causative mutation was mapped almost 20 years ago, its molecular nature remained unknown. Here, we report allelic heterogeneity of the POLLED locus. First, we mapped the POLLED locus to a ∼381-kb interval in a multi-breed case-control design. Targeted re-sequencing of an enlarged candidate interval (547 kb) in 16 sires with known POLLED genotype did not detect a common allele associated with polled status. In eight sires of Alpine and Scottish origin (four polled versus four horned), we identified a single candidate mutation, a complex 202 bp insertion-deletion event that showed perfect association to the polled phenotype in various European cattle breeds, except Holstein-Friesian. The analysis of the same candidate interval in eight Holsteins identified five candidate variants which segregate as a 260 kb haplotype also perfectly associated with the POLLED gene without recombination or interference with the 202 bp insertion-deletion. We further identified bulls which are progeny tested as homozygous polled but bearing both, 202 bp insertion-deletion and Friesian haplotype. The distribution of genotypes of the two putative POLLED alleles in large semi-random sample (1,261 animals) supports the hypothesis of two independent mutations
