On the Romance of Leadership – In Memory of James R. Meindl

It was a shock to the community when three years ago James Meindl suddenly passed away. Leadership research lost one of its best scholars. This special issue is dedicated to one of Meindl\u27s most influential research contributions, the Romance of Leadership perspective. First introduced in 1985 by Meindl, Ehrlich, and Dukerich, the Romance of Leadership refers to the tendency to attribute responsibility for company performance to leaders, thereby disregarding other factors that might be of influence

Prosociality and Hoarding amid the COVID-19 Pandemic: A Tale of Four Countries

The COVID-19 pandemic is an unprecedented public health crisis that poses a challenge to humanity. Drawing on the stress and coping literature, we argue that people around the world alleviate their anxiety and stress induced by the pandemic through both prosocial and `self-interested' hoarding behaviours. This cross-cultural survey study examined the pushing (threat perception) and pulling (moral identity) factors that predicted prosocial acts and hoarding, and subsequently psychological well-being. Data were collected from 9 April to 14 May 2020 from 251 participants in the United Kingdom (UK), 268 in the United States (US), 197 in Germany (DE), and 200 in Hong Kong (HK). Whereas threat perception was associated positively with both prosocial acts and hoarding, benevolent moral identity was associated positively with the former but not the latter behaviour. We also observed cross-cultural differences, such that both effects were stronger in more individualistic (UK, US) countries than less individualistic (HK, DE) ones. The findings shed light on the prosocial vs. self-interested behavioural responses of people in different cultures towards the same pandemic crisis. \textcopyright 2021 The Authors.

Lipid composition changes induced by tamoxifen in a bacterial model system

A putative relationship between growth impairment of Bacillus stearothermophilus by tamoxifen (TAM) and TAM-induced perturbation of the physical properties of bacterial membrane lipids has been observed. The supplementation of the growth medium with Ca2+ (a membrane stabilizer) partially relieves growth inhibition by TAM, allowing growth at TAM concentrations that fully impair growth in the basal medium. B. stearothermophilus modifies the membrane lipid composition in response to the addition of TAM to the growth medium and the response is sensitive to Ca2+. Changes in lipid composition are observed in the acyl chains and in the polar head groups of phospholipids. The physical effects of alteration in these lipids was studied by fluorescence polarization of DPH and DPH-PA. Polar lipid dispersions from TAM-adapted cells grown in a Ca2+ medium show a shift of Tm to higher temperatures and a significant increase of the structural order as compared to lipids from control cells, suggesting that TAM-induced lipid composition changes compensate for the destabilizing effects of the cytostatic on membrane organization. The polar lipids from cells grown in the basal medium containing tamoxifen are also altered, but these alterations do not promote order increase of the bilayer in spite of a deviation of Tm to higher temperatures as detected by DPH. Data indicate that B. stearothermophilus controls the membrane lipid composition in response to tamoxifen, to compensate for TAM-promoted disordering in membranes and to provide an appropriate packing of phospholipid molecules in a stable bilayer, putatively disturbed by TAM incorporation.http://www.sciencedirect.com/science/article/B6T1T-3Y6PVPV-9/1/5fd659e10f4fc0e7d0a423e4e48becd
