ELF - student perspective
No full textEnthusiastic teaching has been linked to student well-being, motivation, and achievement (Frenzel et al., 2018; Keller et al., 2016; Kunter et al., 2011; Parrisius et al., 2020). However, these studies were mainly conducted in secondary education contexts, that is, with school teachers and school students. However, little is known about how enthusiasm for subject and teaching can be assessed in tertiary education contexts, that is, in university lectures and students, and how students infer from observable behaviors how enthusiastic their lecturers are.
The goal of the present study is therefore to develop and validate a high-inference self-report questionnaire instrument to assess perceived lecturer enthusiasm of university students both with respect to its dimensionality and relations to student-observed behavioral indicators of lecturer enthusiasm in a lower-inference questionnaire (Keller et al., 2016).

Description of atmospheric conditions at the Pierre Auger Observatory using the Global Data Assimilation System (GDAS)
No full textAtmospheric conditions at the site of a cosmic ray observatory must be known for reconstructing observed extensive air showers. The Global Data Assimilation System (GDAS) is a global atmospheric model predicated on meteorological measurements and numerical weather predictions. GDAS provides altitude-dependent profiles of the main state variables of the atmosphere like temperature, pressure, and humidity. The original data and their application to the air shower reconstruction of the Pierre Auger Observatory are described. By comparisons with radiosonde and weather station measurements obtained on-site in Malargüe and averaged monthly models, the utility of the GDAS data is shown. © 2012 Elsevier B.V.

Measurement of the energy spectrum of cosmic rays above 10(18) eV using the Pierre Auger Observatory
No full textWe report a measurement of the flux of cosmic rays with unprecedented precision and statistics using the Pierre Auger Observatory. Based on fluorescence observations in coincidence with at least one surface detector we derive a spectrum for energies above 10¹⁸ eV. We also update the previously published energy spectrum obtained with the surface detector array. The two spectra are combined addressing the systematic uncertainties and, in particular, the influence of the energy resolution on the spectral shape. The spectrum can be described by a broken power law E−γ with index γ=3.3 below the ankle which is measured at log10(Eankle/eV)=18.6. Above the ankle the spectrum is described by a power law with index 2.6 followed by a flux suppression, above about log10(E/eV)=19.5, detected with high statistical significance.J. Abraham... K. B.

The Lateral Trigger Probability function for the Ultra-High Energy Cosmic Ray showers detected by the Pierre Auger Observatory
No full textIn this paper we introduce the concept of Lateral Trigger Probability (LTP) function, i.e., the probability for an Extensive Air Shower (EAS) to trigger an individual detector of a ground based array as a function of distance to the shower axis, taking into account energy, mass and direction of the primary cosmic ray. We apply this concept to the surface array of the Pierre Auger Observatory consisting of a 1.5 km spaced grid of about 1600 water Cherenkov stations. Using Monte Carlo simulations of ultra-high energy showers the LTP functions are derived for energies in the range between 1017 and 1019 eV and zenith angles up to 65°. A parametrization combining a step function with an exponential is found to reproduce them very well in the considered range of energies and zenith angles. The LTP functions can also be obtained from data using events simultaneously observed by the fluorescence and the surface detector of the Pierre Auger Observatory (hybrid events). We validate the Monte Carlo results showing how LTP functions from data are in good agreement with simulations. © 2011 Published by Elsevier B.V.The Pierre Auger Collaboration... P. Abreu... K. B.

Search for signatures of magnetically-induced alignment in the arrival directions measured by the Pierre Auger Observatory
No full textWe present the results of an analysis of data recorded at the Pierre Auger Observatory in which we search for groups of directionally-aligned events (or 'multiplets') which exhibit a correlation between arrival direction and the inverse of the energy. These signatures are expected from sets of events coming from the same source after having been deflected by intervening coherent magnetic fields. The observation of several events from the same source would open the possibility to accurately reconstruct the position of the source and also measure the integral of the component of the magnetic field orthogonal to the trajectory of the cosmic rays. We describe the largest multiplets found and compute the probability that they appeared by chance from an isotropic distribution. We find no statistically significant evidence for the presence of multiplets arising from magnetic deflections in the present data. © 2011 Elsevier B.V. All rights reserved.P. Abreu... K. B.
