- On 17 March 2020, Postdigital Science and Education launched a call for testimonies about teaching and learning during very frst Covid-19 lockdowns. The resulting article, ‘Teaching in the Age of Covid-19’ (attached), presents 81 written testimonies and 80 workspace photographs submitted by 84 authors from 19 countries. On 17 March 2021, Postdigital Science and Education launched a call for a sequel article of testimonies about teaching and learning during very first Covid-19 lockdowns. The resulting article, ‘Teaching in the Age of Covid-19—1 Year Later’(attached), consists of 74 textual testimonies and 76 workspace photographs submitted by 77 authors from 20 countries.These two articles have been downloaded almost 100,000 times and have been cited more than 100 times. This shows their value as historical documents. Recent analyses, such as ‘Teaching in the Age of Covid-19—A Longitudinal Study ’(attached), also indicate their strong potential for educational research. As the Covid-19 pandemic seems to wind down, pandemic experiences have entered the mainstream. They shape all educational research of today and arguably do not require special treatment. Yet, our unique series of pandemic testimonies provides a unique opportunity to longitudinally trace what happens to the same people over the years—and this opportunity should not be missed.Today, we launch a call for fnal sequel: Teaching in the Age of Covid-19—The New Normal. In this sequel, we would like to hear about ways in which you—contributors to the previous articles—have established your own new normal. We hope that this will be the last iteration in this series of testimony articles. Unless the world faces another strong pandemic outburst, we would like to end the series with this last article.

Optical anisotropy of (001)-GaAs surface quantum wells

- We report a reflectance difference spectroscopy (RDS) study of the optical anisotropy of GaAs:(001) surface quantum wells consisting of a thin GaAs layer (3-30 nm thick) embedded between an arsenic reconstructed surface and an AlAs barrier. The RDS spectra display anisotropic contributions from the free surface and from the GaAs/AlAs interface. By comparing RDS spectra for the c(4×4) and (2×4) surface reconstructions, we separate these two contributions, and demonstrate that the anisotropy around the E1 and E1+Δ1 transitions comprises a component originating from modifications of bulk states near the surface. The latter is attributed to anisotropic strains induced by the surface reconstruction. The experimental data are well described by a model for the RDS response of the multilayer structures, which also takes into account the blue energy shifts and the changes in oscillator strength of the E1 and E1+Δ1 transitions induced by quantum-well confinement.

- The piezo-optical coefficients P11-P12 and P44 have been measured for ZnSe and ZnTe above the fundamental gap (in the energy ranges 2.6-5.5 eV and 2.0-5.5 eV, respectively) by using reflectance difference spectroscopy. The measured spectra of P11-P12 and P44 show good Kramers-Kronig consistency between their real and imaginary parts. Values for the deformation potentials D1 5, D3 3, and D3 5 for the E1 and E1 + Δ1 transitions were estimated by fitting the spectral dependence of P11-P12 and P44 to analytical line shapes based on a one-electron approximation.

Meiofauna of the Koster-area, results from a workshop at the Sven Lovén Centre for Marine Sciences (Tjärnö, Sweden)

Tidskriftsartikel (refereegranskat)abstract
- During a two-week workshop held at the Sven Lovén Centre for Marine Sciences on Tjärnö, an island on the Swedish west-coast, meiofauna was studied in a large variety of habitats using a wide range of sampling tech- niques. Almost 100 samples coming from littoral beaches, rock pools and different types of sublittoral sand- and mudflats yielded a total of 430 species, a conservative estimate. The main focus was on acoels, proseriate and rhabdocoel flatworms, rotifers, nematodes, gastrotrichs, copepods and some smaller taxa, like nemertodermatids, gnathostomulids, cycliophorans, dorvilleid polychaetes, priapulids, kinorhynchs, tardigrades and some other flatworms. As this is a preliminary report, some species still have to be positively identified and/or described, as 157 species were new for the Swedish fauna and 27 are possibly new to science. Each taxon is discussed separately and accompanied by a detailed species list.
