However, the perspectives of German school students, the main addressees of such a shift, are little explored. This article investigates the attitudes to and familiarity with different Englishes among 160 German high school students, using a mix of direct and indirect attitude elicitation methods and a nationality identification task. Informants rated (speakers of) Standard Southern British (StSBrE), Standard American (StAmE), Indian (IndE), German (GerE), and African/Kenyan English (AfrE/KenE). Multivariate analyses revealed that informants are most familiar with StSBrE and StAmE. StSBrE and, to a smaller degree, StAmE are perceived as reference norms, while English as a Second Language (ESL) varieties, especially IndE are rated negatively for competence, professionalism, and intelligibility. Familiarity with specific English as a First/Native Language varieties is linked to more positive attitudes.

Using the grid frequency as an indicator to switch-on and -off certain loads (loads that do not require power permanently (e.g. dishwashers, washing machines, dryers, fridges and freezers, heaters) could provide a simple, inexpensive demand-side-management indicator to lower specific CO2-emissions and costs (if a dynamic consumption tariff is applied). To check the truthfulness of that hypothesis, the grid and frequency data of the German grid of the year 2018 have been collected and the correlations between grid frequency, share of renewables, CO2-contents, and actual price at the European energy exchange (EEX) have been calculated. The results show: Correlation between grid frequency and the share of renewables is quite low (r=0.155) due to the fact that primary grid control quickly compensates deviations from the 50 Hz nominal frequency. As expected, there is a good anti-correlation (r=-0.687) between the EEX-prices and the share of renewables in the grid. Over the years, correlation between electricity trading prices (EEX) and CO2 emissions is quite good (r=0.665), within the one year (2018) that correlation almost doesn't exist, possibly due to the inflexibility of the bulky lignite baseload power plants that even operate at negative prices.}}, author = {{Krauter, Stefan and Zhang, L.}}, booktitle = {{Proceedings of the 47th IEEE Photovoltaic Specialists Conference (PVSC 47) 2020}}, keywords = {{CO2, EEX, Grid frequency, DSM, electricity price, Renewable share}}, location = {{online}}, pages = {{1672--1674}}, title = {{{Correlation of grid-frequency, electricity prices, share of Renewables and CO2-contents of German electricity grid to enable inexpensive triggering of Demand-Side-Management}}}, doi = {{10.1109/PVSC45281.2020.9300487}}, year = {{2020}}, } @article{29545, author = {{Jean, Frédéric and Maslovskaya, Sofya and Zelenko, Igor}}, issn = {{0046-5755}}, journal = {{Geometriae Dedicata}}, keywords = {{Geometry and Topology}}, number = {{1}}, pages = {{295--314}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{On Weyl’s type theorems and genericity of projective rigidity in sub-Riemannian geometry}}}, doi = {{10.1007/s10711-020-00581-z}}, volume = {{213}}, year = {{2020}}, } @article{31264, abstract = {{AbstractGiven a closed orientable hyperbolic manifold of dimension $$\ne 3$$ ≠ 3 we prove that the multiplicity of the Pollicott-Ruelle resonance of the geodesic flow on perpendicular one-forms at zero agrees with the first Betti number of the manifold.

We provide an alternative algorithm, based only on the simple observation that an R-trivial monoid may be realized by upper triangular matrices. This approach is inspired by results in the field of coupled cell network dynamical systems, where L-trivial monoids (the opposite notion) correspond to so-called feed-forward networks. We first show that our algorithm works for ZM, after which we prove that it also works for RM where R is an arbitrary ring with a known complete system of primitive orthogonal idempotents. In particular, our algorithm works if R is any field. In this respect our result constitutes a considerable generalization of the results in Berg et al. [J. Algebra 348 (2011) 446–461]. Moreover, the system of idempotents for RM is obtained from the one our algorithm yields for ZM in a straightforward manner.
