    Abstract A successful e-participation campaign in urban planning relies on good two-way communication between the expert and the citizen. While the presentation of information from planners to citizens is one concern of that topic, we address in this paper the question of how citizens’ inputs can be evaluated for map-based e-participation tools. The interest is, on the one side, in the usefulness of the input for the planner and, on the other side, in performing a quick assessment which can provide feedback to the participant via the tool’s interface. We use a test dataset that was acquired with an online city planning tool that uses 3D geometries and develop analysis methods from it that can also be generalized for other map-based e-participation tools. These analysis methods are meant to be applied to large datasets and to enhance e-participation methods in urban planning and design to citizen (design) science approaches. The methods range from the calculation of simple parameters and heatmaps over clustering to point pattern analysis. We evaluate the presented approaches by their computation time and their usefulness for the planner and non-expert citizen and investigate their potential to serve as a composite analysis. We found that functions of the point pattern analysis reveal relevant information of the users’ inputs but require a simplified presentation. We introduce a spatial dispersion index as an example to present the relations between objects in a clear way.

    Side‐Payments and the Implementation of International Agreements in Federal Systems

    Abstract Federal systems face specific challenges in fulfilling their international commitments. In cases of shared jurisdiction, the federal government needs the sub-federal level to contribute to the implementation process. Both Canada and the EU have used side-payments to bring and keep on board reluctant and opposing provinces and member states in the implementation of international agreements. However, both cases have experienced the limits of this strategy. This article aims to make a theoretical contribution by identifying the causal conditions and processes that help explain the success and failure of using side-payments to encourage sub-federal support for the implementation of an international agreement. Based on the study of the implementation of the Paris Agreement in Canada and the EU, I develop a two-fold argument. First, side-payments can be an effective tool to persuade sub-federal governments if they are generally interested in contributing to implementation. They do not work for governments of powerful entities that are unwilling to implement. Second, sub-federal governments react to other actors’ conduct. Side-payments can keep reluctant governments of weak entities on board only as long as no alliance of powerful sub-federal entities is formed that resists the implementation of an international agreement.

    Abstract Research on sexual diversity in physical education (PE) focuses primarily on students and rarely on teachers. Against this background, this study takes a look at teachers and explores the question of how lesbian, gay, and bisexual (LGB) teachers experience PE. Our study was conceived as a systematic literature review of qualitative studies published between 1990 and 2022. The processual study selection was carried out according to PRISMA. A total of nine studies were identified that met our inclusion criteria. We analyzed and compared the findings of these studies. On an overarching level, our analysis shows that the identified studies predominantly focus on the challenges and problems associated with the sexuality of LGB teachers. Furthermore, our analysis shows that the PE teachers interviewed in the studies perceive and anticipate school as a homophobic context. From the teachers’ perspective, PE is a special subject that they experience as particularly risky due to their sexuality. Against the backdrop of these experiences, many PE teachers use protective strategies, which mainly consist of hiding their own sexuality and ignoring the perceived homophobia. In the end, research implications are discussed, highlighting the need for ongoing research on LGB PE teachers.

    Abstract Abstract Background Previous studies about health in prisons conclude that incarceration has detrimental consequences for physical and mental health. It is associated with weight gain, decreased fitness, increased cardiovascular risks, and increased risks for mental illnesses, like depression and anxiety. This article examines the relationships between sports activity and health developments among prisoners. We analyze data from the Hessian Prison Sports Study, conducted in 12 prisons of the federal state of Hesse, Germany. Results Based on quantitative survey data of 568 prisoners in regular custody, our empirical findings show that inmates perceive substantial health declines since incarceration. They report substantial decreases in general health (d=-0.52) and life satisfaction (d=-0.84) as well as an increased number of health problems (d = 0.71). However, sport has a potential to buffer this decline of health. Prisoners engaged in sports report a less negative development of their health compared to inactive prisoners. The greater the amount of time spent with sports activities, the better are the health trajectories found. Conclusion Findings add to the public health and prison sport literature by demonstrating health benefits of sporting activities in a vulnerable population group that almost inevitably is exposed to manifold strains and burdens.

    Abstract In the last decades, EU studies have increasingly broadened in terms of their theoretical and methodological approaches. By now, comparative concepts and theories are an integral part of studying the EU, which aids the study of its polity, politics, and policies. Despite the indisputable peculiarity of the EU as a political system, many scholars have stressed the value of using comparative approaches to study it. This thematic issue aims to investigate a specific case—the political system of Canada—as to its merit for comparison with the EU. While both systems have been described as sui generis in the past, forming a class of political system by themselves, recently the similarities between both have been stressed. This thematic issue gathers articles that compare different aspects of these two systems—focusing on polity, politics, and policy—to reap the benefits of the comparative approach and gain new insights into the functioning of both systems. The contributions to the thematic issue show the benefits that both Canadian political science and EU studies can gain from engaging in comparative exercises.

    Abstract Vaccination hesitancy is a major obstacle to achieving and maintaining herd immunity. Therefore, public health authorities need to understand the dynamics of an anti-vaccine opinion in the population. We introduce a spatially structured mathematical model of opinion dynamics with reinforcement. The model allows as an emergent property for the occurrence of echo chambers, i.e. opinion bubbles in which information that is incompatible with one’s entrenched worldview, is probably disregarded. We scale the model both to a deterministic limit and to a weak-effects limit, and obtain bifurcations, phase transitions and the invariant measure. Fitting the model to measles and meningococci vaccination coverage across Germany, reveals that the emergence of echo chambers dynamics explains the occurrence and persistence of the anti-vaccination opinion in allowing anti-vaxxers to isolate and to ignore pro-vaccination facts. We predict and compare the effectiveness of different policies aimed at influencing opinion dynamics in order to increase vaccination uptake. According to our model, measures aiming at reducing the salience of partisan anti-vaccine information sources would have the largest effect on enhancing vaccination uptake. By contrast, measures aiming at reducing the reinforcement of vaccination deniers are predicted to have the smallest impact.

    Abstract It is widely assumed that LGBT+ people may feel insecure and unwelcome in sports settings, which are often characterized by a binary gender order and a culture of heteronormativity. Previous research also suggests that LGBT+ individuals experience homophobia in the context of sport. Despite these findings, reliable quantitative data on the sports participation levels of sexual minority groups are scarce. The paper addresses this academic void by analyzing sports activity data of sexual minority groups. The 2019 wave of the German Socio-Economic Panel (SOEP) study is analyzed, which includes a novel LGBT+ boost sample of respondents who self-identify as lesbian, gay, bisexual, transgender, or non-binary with regard to gender. The analysis of this sample shows that sports activity levels (with regard to frequency and duration) of homo- and bisexual individuals are comparable to the heterosexual majority. Although findings show that a high share of homo- and bisexual individuals experience sexual discrimination, discrimination is not associated with lower participation rates in sports. We thus conclude that the domain of sport—although by no means free of discrimination—offers sufficient participation opportunities for LGBT+ people.

    Abstract MATSim is an open-source simulation framework for mesoscopic traffic simulations that has gained popularity in recent years. In this paper, we present a MATSim model for the city of Vienna, with a particular emphasis on the intermodal routing framework used to create agent trips, and the development of a utility function to specify different agents’ mode preferences. To create agent activity chains, we use mobility diaries from the national transportation survey in Austria and disaggregate the available geospatial information to best fit the reported travel times. The novelty of the intermodal framework is the ability to create trips that do not consist of only one mode of transportation, but to also include bicycle, car, and demand-responsive transport (e.g., cab, car sharing) trips in combination with public transportation. To represent the different mobility behaviors of agents, we divide the population into groups and assign them different utility functions for transportation modes according to their socio-demographic characteristics. After presenting the validation of the model, we discuss ways to improve the model.
