A key Eurosceptic argument is that countries can selectively retain only those aspects of European integration from which they benefit, while opting out of those aspects they dislike. How convincing is this "have your cake and eat it, too" argument to voters? This article argues that voters can learn about the feasibility of such a strategy by looking at the experience of countries that pursued a similar path. Positive experiences can strengthen voters' support for a similar strategy, while negative experiences can deter them. This argument is tested in a study of the effects of the Brexit negotiations on public opinion in Switzerland. Drawing on a panel survey fielded between 2019 and 2021, the article shows that Brexit had a small but non-negligible impact on Swiss voters' expectations about the EU's resolve, as well as on vote intentions on two EU-related policy proposals. These findings confirm that voters learn from foreign political developments about the costs of non-cooperation. [ABSTRACT FROM AUTHOR]

Minoritized groups have been severely affected by the Covid-19 pandemic, highlighting the need to better understand how they and their interests were (not) represented in the political process during this challenging period. We identify common and unique features of Covid-19 and past crises, and discuss why the pandemic may have represented a moment for change before identifying gaps in past research. Finally, we present seven articles in this Special Issue that analyze the political representation of minoritized groups in politics, the news media and online. This Special Issue brings together a diverse group of scholars using different theoretical approaches, methodologies and data sources. Using interdisciplinary and intersectional perspectives, we shed new light on minoritized people’s representation during Covid-19 across the globe, focusing on how ethnic and racial groups have experienced the pandemic themselves.

Nitrogen oxides (NOx), primarily generated from combustion processes, pose significant health and environmental risks. To improve the coordination of measures against excessive NOx emissions, it is necessary to effectively monitor ambient NOx concentrations, which requires the development of precise and cost-efficient detection methods. This study focuses on developing a microwave- or radio frequency (RF)-based gas dosimeter for NOx detection and addresses the optimization of the dosimeter design by examining the dielectric properties of LTCC-based (Low-Temperature Co-fired Ceramics) sensor substrates and barium-based NOx storage materials. The measurements taken utilizing the Microwave Cavity Perturbation (MCP) method revealed that these materials exhibit more pronounced changes in dielectric losses when storing NOx at elevated temperatures. Consequently, operating such a dosimeter at high temperatures (above 300 °C) is recommended to maximize the sensor signal. To evaluate their high-temperature applicability, LTCC substrates were analyzed by measuring their dielectric losses at temperatures up to 600 °C. In terms of NOx storage materials, coating barium on high-surface-area alumina resolved issues related to limited NOx adsorption in pure barium carbonate powders. Additionally, the adsorption of both NO and NO2 was enabled by the application of a platinum catalyst. The change in dielectric losses, which provides the main signal for an RF-based gas dosimeter, only depends on the stored amount of NOx and not on the specific type of nitrogen oxide. Although the change in dielectric losses increases with the temperature, the maximum storage capacity of the material decreases significantly. In addition, at temperatures above 350 °C, NOx is mostly weakly bound, so it will desorb in the absence of NOx. Therefore, in the future development of a reliable RF-based NOx dosimeter, the trade-off between the sensor signal strength and adsorption behavior must be addressed. [ABSTRACT FROM AUTHOR]

The liberal international order has recently come under increasing nationalist pressure, evidenced by a rise in nationalist demands to withdraw from international institutions. A growing literature examines the domestic economic, social, and political origins of this nationalist backlash against international institutions. However, less is known about the extent to which precedents of withdrawals of one country affect nationalist pressures for future withdrawals elsewhere. In this paper, we argue that initial withdrawal episodes provide new information about the feasibility and desirability of withdrawals to nationalist elites in other countries. Hence, we expect nationalists abroad to be either encouraged or deterred to follow a similar path – depending on the success of these precedents. We explore this argument in the context of the British withdrawal from the European Union (Brexit), which arguably marks the most significant withdrawal from an international institution to date. Based on a quantitative analyses of media reports in ten European countries, we show we show that nationalist parties in Europe increased or moderated the aggressiveness about their EU-related rhetoric as the ups and downs of the Brexit-drama unfolded. Our results suggest that precedents of nationalist withdrawals shape domestic politics well beyond the concerned countries themselves. [ABSTRACT FROM AUTHOR]
