Stirring and disturb - urging the movement of academic entrepreneurship onwards

In an epilogue, Daniel Hjorth and Chris Steyaert aim to further multiply the new movements in academic entrepreneurship that this volume identifies. Therefore, they introduce a conceptual quartet that makes and keeps movement going: provocation, mobilization, affirmation, and experimentation. Their conceptual contribution, which has to be seen as an attempt to stir and disturb, relates these four

Supercurrent transport through 1e -periodic full-shell Coulomb islands

We experimentally investigate supercurrent through Coulomb islands, where island and leads are fabricated from semiconducting nanowires with fully surrounding superconducting shells. Applying flux along the wire yields a series of destructive Little-Parks lobes with reentrant supercurrent. We find Coulomb blockade with 2e peak spacing in the zeroth lobe and 1e average spacing, with regions of sign

New movements in entrepreneurship

'Drawing from contributions by scholars of entrepreneurship from North America, Western Europe and Asia, this edited book celebrates the vibrancy and interdisciplinarity of entrepreneurship research. It showcases the renewed importance of entrepreneurship studies in the social sciences. New Movements in Entrepreneurship is a tour de force in entrepreneurship studies that must not be missed. It's b

Nietzsche as educator

Our title is a play on Nietzsche’s Schopenhauer as Educator first published in his essay collection Unfashionable Observations. Within the setting of teaching and studying management practice our chapter is also unfashionable. It argues for a primacy of honesty in feeling in a practice that can encourage the rational selection and manipulation of viewpoints. It argues for cheerful and generous exp

Formation of wide-orbit giant planets in protoplanetary disks with a decreasing pebble flux

The presence of distant protoplanets may explain the observed gaps in the dust emission of protoplanetary disks. Here, we derive a novel analytical model to describe the temporal decay of the pebble flux through a protoplanetary disk as the result of radial drift. This has allowed us to investigate the growth and migration of distant protoplanets throughout the lifespan of the disk. We find that M

Synthesis of gem-Difluorinated 2,3-Dihydrobenzofurans Using Freon-22 via [4 + 1] Annulation of Difluorocarbene and Antitumor Activity Evaluation

As an inexpensive industrial chemical, chlorodifluoromethane (Freon-22), despite its relatively low reactivity, can serve as a practical CF2 source for the construction of gem-difluorinated ring structures. Here, we develop a protocol for the efficient assembly of valuable fluorinated 2,3-dihydrobenzofurans from the [4 + 1] annulation in good yields under basic conditions. The reliable practicabil

Enhanced surveillance of hospitalized COVID-19 patients in Europe : an evaluation of the I-MOVE-COVID-19 surveillance network

Background: A pre-existing, well-established European influenza surveillance network known as I-MOVE enabled the rapid implementation of a European multi-country COVID-19 hospital surveillance network for surveillance of hospitalized COVID-19 cases in early 2020. This network included 257 hospitals in 11 surveillance sites across nine countries. We aimed to identify whether the surveillance object

Majorana Qubits and Non-Abelian Physics in Quantum Dot-Based Minimal Kitaev Chains

The possibility of engineering artificial Kitaev chains in arrays of quantum dots coupled via narrow superconducting regions has emerged as an attractive way to overcome the disorder issues that complicate the realization and detection of topological superconducting phases in other platforms. Although a true topological phase would require long chains, a two-site chain realized in a double quantum
