Abstract
We perform a systematic study of the α-particle excitation from its ground state 0_{1}^{+} to the 0_{2}^{+} resonance. The so-called monopole transition form factor is investigated via an electron scattering experiment in a broad Q^{2} range (from 0.5 to 5.0 fm^{-2}). The precision of the new data dramatically supersedes that of older sets of data, each covering only a portion of the Q^{2} range. The new data allow the determination of two coefficients in a low-momentum expansion, leading to a new puzzle. By confronting experiment to state-of-the-art theoretical calculations, we observe that modern nuclear forces, including those derived within chiral effective field theory that are well tested on a variety of observables, fail to reproduce the excitation of the α particle.

Abstract
A novel species of Hericium was recently collected in the Afrotemperate forests (Knysna - Amatole region) of Southern Africa. The novel species shares many similar, dentate features common to other species in Hericium, and its basidiome first appears stark white and yellows with age. However, the substrate choice and gloeocystidia and basidiospore sizes of the specimens collected were distinct from other Hericium species. This was confirmed by sequencing the ITS and 28S genetic markers, respectively. The novel species is described as Hericium ophelieae sp. nov. and appears unique as it grows on hardwoods indigenous to Southern Africa. The species has larger basidiospores and wider gloeocystidia compared to its closest relative. H. ophelieae sp. nov. is the first endemic species of the medicinal mushroom genus Hericium to be described from Southern Africa, and the second to be described from Africa, after its closest relative, H. bembedjaense, which was isolated in Cameroon. Although this is the first Hericium to be described from the Southern African region, there are likely others to be discovered, and this study highlights the need for further research into the fungal diversity of Afrotemperate environments.

Abstract
Following the massive impact of the Covid-19 pandemic on the global economy and on small and medium-sized enterprises (SMEs) in particular, the concept of resilience has experienced a renaissance. As an organizational concept, business model resilience describes the extent to which an organization can maintain or quickly recover its value proposition despite unexpected current or future disruptions (Palzkill-Vorbeck 2018). Although research has been conducted in this area for decades, there is still a lack of a unified framework that brings together the findings from research and links them to organizational practice. The paper addresses this gap by developing a framework for business model resilience and demonstrating its practical relevance for organizational performance during the Covid-19 pandemic in 2020. The framework includes 11 factors that characterize the resilience of an organization's business model. For managers and decision-makers, the framework is an opportunity to assess and improve the resilience of their organizations. For researchers, the framework is an important foundation for transferring the concept of business model resilience into organizational practice.

Abstract
We report on the first Q^{2}-dependent measurement of the beam-normal single spin asymmetry A_{n} in the elastic scattering of 570 MeV vertically polarized electrons off ^{12}C. We cover the Q^{2} range between 0.02 and 0.05 GeV^{2}/c^{2} and determine A_{n} at four different Q^{2} values. The experimental results are compared to a theoretical calculation that relates A_{n} to the imaginary part of the two-photon exchange amplitude. The result emphasizes that the Q^{2} behavior of A_{n} given by the ratio of the Compton to charge form factors cannot be treated independently of the target nucleus.
