The spatial dynamics of the optical emission from an array of 50 times 50 individual microcavity plasma devices is investigated. The array is operated in argon and argon-neon mixtures close to atmospheric pressure with an ac voltage. The optical emission is analysed with phase and space resolution. It has been found that the emission is not continuous over the entire ac period, but occurs once per half period. Each of the observed emission phases shows a self-pulsing of the discharge, with (...) several bursts of emission of fixed width and repetition rate. The number of emission bursts depends on applied voltage and frequency. Spatially resolved measurements prove that the emission bursts are formed by overlapping emission pulses from single discharge cavities. Intensity differences between positive and negative half-wave can be interpreted through spatially resolved measurements of single discharge cavities. (shrink)

We have evolved to become who we are, at least in part, due to our general drive to create new things and ideas. When seeking to improve our creations, ideas, or situations, we systematically overlook opportunities to perform subtractive changes. For example, when tasked with giving feedback on an academic paper, reviewers will tend to suggest additional explanations and analyses rather than delete existing ones. Here, we show that this addition bias is systematically reflected in English language statistics along several (...) distinct dimensions. First, we show that words associated with an increase in quantity or number (e.g., add, addition, more, most) are more frequent than words associated with a decrease in quantity or number (e.g., subtract, subtraction, less, least). Second, we show that in binomial expressions, addition-related words are mentioned first, that is, add and subtract rather than subtract and add. Third, we show that the distributional semantics of verbs of change, such as to improve and to transform, overlap more with the distributional semantics of add/increase than subtract/decrease, which suggests that change verbs are implicitly biased toward addition. Fourth, addition-related words have more positive connotations than subtraction-related words. Fifth, we demonstrate that state-of-the-art large language models, such as the Generative Pre-trained Transformer (GPT-3), are also biased toward addition. We discuss the implications of our results for research on cognitive biases and decision-making. (shrink)

Bullying often results in negative coping in victims, including an increased consumption of alcohol. Recently, however, an increase in alcohol use has also been reported among perpetrators of bullying. The factors triggering this pattern are still unclear. We investigated the role of empathy in the interaction between bullying and alcohol use in an adolescent sample (IMAGEN) at age 13.97 (±0.53) years (baseline (BL), N = 2165, 50.9% female) and age 16.51 (±0.61) years (follow-up 1 (FU1), N = 1185, 54.9% female). (...) General empathic distress served as a significant moderator of alcohol use in perpetrators (F9, 493 = 17.978, p < 0.01), which was specific for males and FU1. Male perpetrators, who are generally less sensitive to distress, might thus be more vulnerable to alcohol abuse. (shrink)

Ontic structural realists Ladyman and Ross endorse the view that the only metaphysical tasks worth pursuing are to unify the sciences and model the objective structure of reality. This form of radically naturalized metaphysics, however, depends upon the principle of naturalistic closure. In this paper I argue that the principle of naturalistic closure is at odds with radically naturalized metaphysics since it is a nonnaturalized metaphysical principle, claiming that radically naturalized metaphysics is not the only form of metaphysics worth doing. (...) In particular, the principle of naturalistic closure requires that a metaphysical claim M at t be of service to some scientific hypothesis H. The principle, however, does not state when M must be of service to H. It is possible for a metaphysical claim at t to be of service to a scientific hypothesis at t+n. Furthermore, the principle of naturalistic closure is not a direct result of scientific inquiry. Yet, as I argue, the principle of naturalistic closure is a metaphysical claim. Thus, motivating the position that metaphysics is not restricted to the tasks of unifying the sciences and modeling the objective structure of reality, but more importantly that it should not be.

Cheating evolves constantly. Dozens of athletes were barred from the Winter Olympics for taking banned substances. Gene doping is on the horizon. Questions have arisen about which athletes count as “female.” What does it take to keep sports fair? And what does fairness require?
