Listening position preference for different 5.0 reproductions -- data
<p>We performed an experiment which investigated the preferred listening position<br> in a 5.0 surround setup out of nine different positions while listening to a<br> classical piece of music.<br> The test was performed by binaural synthesis in order to allow instantaneous<br> switching between the different positions and was performed first without<br> indicating to the participants where they are located in the virtual setup and a<br> second run, where they got visual feedback on their virtual position.</p> <p>The experiment was repeated for six different recording techniques, that captured the Mozart performance simultaneously [2].</p> <p>See README.md for more details.</p> <p>[1] https://github.com/SoundScapeRenderer/ssr</p> <p>[2] Wittek, H.

Received Signal Srength (RSS) urban measurements from GSM and UMTS networks for cellular-based positioning
<p>GSM (2G) and UMTS (3G) urban measurement data for cellular-based positioning. The data has been collected in Tampere city, Finland with a mobile phone with proprietary software. The data is given in Matlab *mat format and it contains a cell variable called BS_grid* which shows the GPS coordinates (x,y,z) (converted in local coordinates, in meter values) and the collected RSS value (in dB) per transmitter (i.e., BS or Node B). Each cell contains a N x 4 matrix, whose rows are [x y z RSS]. N is the number of measurements points in which the corresponding Base Station were heard. The size of the BS_grid* cells is equal to the number of heard Base Stations in the measured area. </p> <p>Example of research results based on these measurements can be found for example in:</p> <ul> <li>H. Nurminen, J. Talvitie, S. Ali-Loytty, P. Muller, E.S. Lohan, R. Piche, M.

When fear meets anger: Attitudes toward positively versus negatively evaluated pandemic policy proposals when negative emotions are competing in society
<p>Since the outbreak of the COVID‐19 pandemic, citizens of many countries have been faced with health‐related fear, as well as anti‐establishment and anti‐governmental anger. This emotional landscape colored the ongoing efforts by the authorities to convince citizens to accept various public policy proposals. In two studies (total <em>N</em> = 528, one preregistered) conducted in Poland in two different situations, we focused on the role of the simultaneously evoked pandemic fear and anti‐government anger in shaping attitudes toward the pandemic regulations. For negatively evaluated proposals, both of these emotions worked in opposite directions: fear was associated with increasing support, while anger was associated with increasing rejection. However, for positively evaluated policy proposals, fear and anger worked in consonance, and both were associated with increasing acceptance of the proposed regulations. Thus, while fear seems to motivate the acceptance of even negatively evaluated proposals that are seen as protective ones, anger works to amplify or polarize the proposals’ basic evaluations. Our findings could help plan the implementation of public policies in societies in times of turbulent emotional landscapes.</p>
Dataset for: Integrated trophic position as a proxy for food-web complexity
<div> <p>There are two distinct approaches to describing the distributions of biomass and species in food webs: one to consider them as discrete trophic levels (TLs); and the other to consider them as continuous trophic positions (TPs). Bridging the gap between these two perspectives presents a non-trivial challenge in integrating biodiversity and food-web structure.</p> <p>Food Network Unfolding (FNU) is a technique used to bridge this gap by partitioning the biomass of species into integer TLs to compute three complexity indices, namely vertical (<em>D</em><sub>V</sub>), horizontal (<em>D</em><sub>H</sub>), and range (<em>D</em><sub>R</sub>) diversity (<em>D</em> indices), through decomposition of Shannon's index <em>H'</em>. Using FNU, the food web (a network of species with unique TPs) is converted to a linear food chain (a biomass distribution at discrete TLs). This enables us to expect that the unfolded biomass within species decreases exponentially as the TL increases. Under this condition, the mean TL value in unfolded food chains is hypothesized to have an exponential relationship with the vertical diversity, <em>D</em><sub>V</sub>. To explore this, we implemented FNU and calculated <em>D</em> indices for food webs publicly available at EcoBase (<em>n</em> = 158) and calculated the integrated TP (iTP), defined as the biomass-weighted average TP of a given food web. The iTP corresponds to the mean TL in unfolded food chains and can be empirically measured through compound-specific isotope analysis of amino acids (CSIA-AA).</p> <p>Although our analysis is biased towards marine ecosystems, we revealed an exponential relationship between iTP and <em>D</em><sub>V</sub>, suggesting that iTP can serve as a measurable proxy for <em>D</em><sub>V</sub>. Furthermore, we found a positive correlation between the iTP observed in the total communities (total iTP) and the iTPs of partial communities consisting only of species with 2.0 ≤ TP < 3.0 (partial iTP; <em>r<sup>2</sup></em> = 0.48), suggesting that <em>D</em><sub>V</sub> can be predicted using partial iTP.</p> <p>Our findings suggest that the net effect of species diversity, excluding the effect of biomass (corresponding to <em>H'</em> − <em>D</em><sub>V</sub>), on food-web complexity can be revealed by combining CSIA-AA with biodiversity analysis (e.g., environmental DNA).</p> </div>
