A large multi-country outbreak of monkeypox across 41 countries in the WHO European Region, 7 March to 23 August 2022

Following the report of a non-travel-associated cluster of monkeypox cases by the United Kingdom in May 2022, 41 countries across the WHO European Region have reported 21,098 cases and two deaths by 23 August 2022. Nowcasting suggests a plateauing in case notifications. Most cases (97%) are MSM, with atypical rash-illness presentation. Spread is mainly through close contact during sexual activities. Few cases are reported among women and children. Targeted interventions of at-risk groups are needed to stop further transmission. © 2022 European Centre for Disease Prevention and Control (ECDC).

Rapid Access to an Oxido-Alkylidene Complex of Mo(VI)

The first well-defined Mo oxido-alkylidene complex, [(^tBu₃PN)₂Mo­(O)­(CHSiMe₃)] (<b>4</b>), and its borane adduct, [(^tBu₃PN)₂Mo­(O–B­(C₆F₅)₃)­(CHSiMe₃)] (<b>5</b>), have been prepared through alkylation of the bis­(phosphinimide) Mo oxido-dichlorido complex [(^tBu₃PN)₂MoOCl₂] (<b>3</b>). The reaction between 2 equiv of ^tBu₃PN–SiMe₃ (<b>2</b>) and [(DME)­MoO₂Cl₂] (<b>1</b>) generates <b>3</b> through selective elimination of (Me₃Si)₂O. All complexes have been studied in solution by multinuclear NMR spectroscopy and in the solid state by X-ray crystallography. Preliminary ROMP catalysis results are also presented

Collective moral disengagement and its associations with bullying perpetration and victimization in students

The aim of the current study was to examine whether collective moral disengagement in the classroom was associated with bullying perpetration and victimisation. One-thousand-and-fifty-four students from 70 classrooms in 29 schools in the middle and southern parts of Sweden completed a questionnaire in their classroom. In line with the hypotheses, the bivariate correlation analyses at the classroom level showed that students who belonged to classrooms with lower collective moral disengagement were less likely to be victimised by bullying or engaged in bullying perpetration. Moreover, when controlling for gender and age at the individual level and including collective moral disengagement in the same model at the classroom level, multilevel analyses revealed that students who belonged to classrooms with a higher level of collective moral disengagement were more likely to be engaged in bullying perpetration or to be targets of bullying victimisation

Magnetic-Order-Induced Crystal Symmetry Lowering inACr2O4Ferrimagnetic Spinels

We demonstrate that the onset of complex spin orders in ACr2O4 spinels with magnetic and Jahn-Teller active A=Fe and Cu ions lowers the lattice symmetry. This is clearly indicated by the emergence of anisotropic lattice dynamics-i.e., by the pronounced phonon splittings-even when experiments probing static distortions fail. The crystal symmetry in the magnetic phase is reduced from tetragonal to orthorhombic for both compounds. The conical spin ordering in FeCr2O4 is also manifested in the hardening of the phonon frequencies. In contrast, the multiferroic CoCr2O4 with no orbital degrees of freedom shows tiny deviations from cubic structure even in its ground state. © 2009 The American Physical Society
