Bram Peper resigned as Minister of Home Affairs and Relations with the Dutch Antilles on March 13, after he had been accused of illegitimate declaration of expenses in the years 1982–1998, when he was burgomaster (mayor) of Rotterdam. Peper denied the accusations, but felt he had to resign in order to defend himself. His expenses had been investigated by a committee of the Rotterdam city council. The public prosecutor also investigated Peper’s behaviour, but decided in December that there was no reason to prosecute him.
Modern democracies are dependent on regular elections and citizens’ legitimacy beliefs. Studies have shown that repeated electoral defeats are associated with lower levels of satisfaction with democracy and political trust. However, previous studies have only considered one type of legitimacy belief at a time, never in comparison. What is more, all previous work is based on observational studies and has not been able to identify any causal effects of losing repeatedly. Building on previous work and classic theories of political legitimacy beliefs, we argue that repeatedly losing in elections represents a form of long‐term exclusion from democratic power that has additional negative effects on people's legitimacy beliefs because they lose faith in the system and start questioning its evenhandedness. We support our predictions using six‐wave panel data and test our hypothesis a total of 16 times within the same context. The findings show that repeated losers are never less satisfied with democracy but that an additional electoral loss leads to lower levels of political trust. The findings have important implications for the meaning of different indicators of legitimacy beliefs but also for electoral research and the underpinnings of stable democracies.
We study the surfing motion of an active particle along a planar interface, separating a semi-infinite layer of gas from a deep layer of liquid. The interface-trapped particle self-propels, thanks to an uneven distribution of surface tension in its immediate vicinity, which itself results from a non-uniform release of an active agent from the particle’s surface. We use the reciprocal theorem in conjunction with singular perturbation expansions to calculate the leading-order contributions to the propulsion speed of the surfer due to the advective transport of mass and momentum when the Péclet and Reynolds numbers (denoted by $\textit{Pe}$ and $\textit{Re}$, respectively) are small but finite. Assuming that the surface tension varies linearly with the concentration of the agent with a slope of negative $\alpha$, we show, perhaps unexpectedly, that the normalised speed for a purely translating (but otherwise arbitrarily shaped) particle, independent of the agent discharge mechanism, can be expressed as $\mathscr{U} = 1 + \mathscr{A} ( 2 \textit{Pe} \ln \textit{Pe} + \textit{Re} \ln \textit{Re} ) + \mathscr{O}(\textit{Pe}) + \mathscr{O}(\textit{Re})$, where the prefactor $\mathscr{A}$ is positive for negative $\alpha$ and vice versa. For reference, the self-propulsion speed of autophoretic Janus spheres varies with $\textit{Pe}$ as $\mathscr{U} = 1 + \mathscr{B} \, \textit{Pe} + {\cdots}$, where $\mathscr{B}$ is positive when the mobility coefficient of the particle is negative and vice versa. Also, the speed of spherical squirmers changes with $\textit{Re}$ as $\mathscr{U} = 1 + \mathscr{C} \, \textit{Re} + \mathscr{O}(\textit{Re})^2$, with $\mathscr{C}$ being positive for pushers and negative for pullers. Our asymptotic formula reveals that the speed of a Marangoni surfer is a non-monotonic function of the Péclet and Reynolds numbers, hinting at the existence of optimal values for both $\textit{Pe}$ and $\textit{Re}$. The information contained within the multiplier $\mathscr{A}$ also offers guidance for customising the shape of the surfer, as well as the release rate and configuration of the agent, to enhance the self-surfing performance. Our general theoretical analysis is complemented by detailed numerical simulations for a representative spherical surfer. These simulations confirm our theoretical predictions and shed light on the effects of intermediate and large values of $\textit{Pe}$ and $\textit{Re}$ on the performance of Marangoni surfers.
Advanced secularization in the Scandinavian countries has not resulted in the elimination of “the religious factor” from political life, rather has it led to a resurgence with the recent establishment in Sweden, Denmark and Finland of native counterparts to Norway's Christian People's Party. The article first examines the development of the characteristic religious cleavage structures of Scandinavia, from the imposed uniformity of the state churches in the early nineteenth century to the relatively open and competitive religious cultures of the twentieth century. The interrelationship between religious cleavages and political alignments is then examined and an attempt made to explain the failure of stable religious parties to emerge in the formative period of the party systems. Finally, the circumstances surrounding the later emergence of the religious parties are described and it is argued that these parties collectively constitute a new species of the genus Christian Democracy, different in kind from Fogarty's Continental and Anglo-Saxon species.
Despite the widespread secularisation of West European societies, research has only found mixed evidence of a decline in the influence of religion on people's electoral preferences. A relatively recent line of inquiry has adopted a ‘top‐down’ approach to this problem, arguing that the impact of religion not only depends on structural social changes, but also on parties’ convergence on moral issues. Drawing upon this ‘top‐down’ approach and the ‘impressionable years’ model, this article argues that parties’ political strategies aimed at (de‐)mobilising social cleavages have a lasting effect on voters’ party preferences. Using nine rounds of the European Social Survey for 19 West European countries, I find the impact of religiosity on voting for the centre‐right (Conservative and Christian Democratic parties) to be significantly smaller for voters who were exposed during emerging adulthood (aged 15–25) to a centre‐right party that adopted similar positions on moral issues to those of its main competitors. These findings have important implications because they highlight the role of generational replacement in bringing about electoral change, even when this is prompted by parties’ strategic choices.
Are personal stories more effective in shaping opinion than experts’ endorsements? This study investigates the persuasiveness of personal stories and expert endorsements in shaping public opinion on education spending and pollution reduction policies. Using a survey experiment in Spain, we found that personal stories consistently increased support for both policies, with a particularly strong effect on citizens with populist attitudes or voters of populist parties. These findings contribute to a better understanding of the success of populist parties and the influence of personal stories on public opinion.
The free movement of people is a fundamental principle of the European Union (EU) that has led to an increase in EU‐internal migration. This study investigates the impact of increased immigration to Germany resulting from the 2004 and 2007 eastern enlargement of the EU on concerns about immigration within the German population. By merging 20 years of annual migration statistics with panel data on individual attitudes and exploiting exogenous variation in the gradual enlargement of the free movement policy, we examine the causal effects of EU‐internal migration on immigration concerns. Our findings suggest that the influx of immigrants from new member states did not have a clear average effect on concerns about immigration, but increased concerns among German natives with materialist‐survival values. The study provides insights into the societal division caused by opposition to immigration as part of the European integration process.
The activity of respiratory viruses (RVs) displays large variability in tropical regions, posing challenges for public health response strategies. Data from most RVs in south-eastern Mexico remain limited, particularly in the Yucatan Peninsula, the largest tourism hub in the country. This retrospective study analyses the regional epidemiology of RVs in Merida, the largest city in the region, using laboratory test data from a local hospital (January 2018–April 2024). Test results of 143292 RVs were collected, including 121976 for SARS-CoV-2, 19355 for influenza A and B viruses, and 1961 for 17 distinct RVs. We found that non-SARS-CoV-2 RVs circulated year-round, with higher activity in autumn and spring, while SARS-CoV-2 peaked in summer and winter. Influenza A virus, respiratory syncytial virus, and influenza B virus reached their highest activity in autumn, earlier than in other regions of Mexico. Human metapneumovirus peaked during autumn-winter. Rhinovirus/enterovirus and parainfluenza showed year-round activity, with peaks in autumn and spring. Other coronaviruses were more frequent during winter-spring. In post-pandemic years (2022–2023), adenovirus outbreaks emerged, as well as an increased prevalence of non-SARS-CoV-2 RV co-infections. This study highlights the need for region-specific public health strategies, including optimized vaccination schedules, such as for influenza A virus, and enhanced diagnostic surveillance.
In many political systems legislators face a fundamental trade‐off between allocating effort to constituency service and to national policy‐making activities, respectively. How do voters want their elected representatives to solve this trade‐off? This article provides new insights into this question by developing a conjoint analysis approach to estimating voters’ preferences over their legislator's effort allocation. This approach is applied in Britain, where it is found that effort allocation has a significant effect on voter evaluations of legislators, even in a political system where other legislator attributes – in particular, party affiliation – might be expected to predominate. This effect is nonlinear, with voters generally preferring a moderate balance of constituency and national policy work. Preferences over legislator effort allocation are not well‐explained by self‐interest or more broadly by instrumental considerations. They are, however, associated with voters’ local‐cosmopolitan orientation, suggesting that heuristic reasoning based on underlying social dispositions may be more important in determining preferences over representative activities.
During the European debt crisis, numerous states launched austerity programmes. The International Monetary Fund (IMF) evaluates and forecasts the likelihood of member states’ success in implementing these programmes. Although IMF evaluations influence country risk perceptions on capital markets, little is known about their reasoning. This article uses fuzzy‐set qualitative comparative analysis (fsQCA) to explore on what grounds the IMF evaluated the success prospects of austerity programmes during the European debt crisis. Results reveal that IMF evaluations are heavily influenced by the programme's implementation credibility. They require a tractable policy problem, a country's institutional capacity to structure implementation, and favour expenditure reduction over revenue measures. By acting as a strict guide on the road to fiscal adjustment, the IMF indirectly influences member states’ scope of policy making through its surveillance activities. Extensive austerity programmes that need to be implemented swiftly are evaluated negatively if the country is not involved in an IMF programme.
Fluid flows around hypersonic vehicles experience chemical non-equilibrium effects at extreme temperature conditions. Reynolds-averaged Navier–Stokes (RANS) equations are primarily used to simulate turbulent external flow at full vehicle scales. However, the turbulent closure of near-wall reactions related to gas dissociation is omitted in practice because it remains unknown how to close the associated mean reaction rate, despite research efforts in this direction for more than a decade. This paper aims to discover an appropriate turbulent closure strategy of the involved finite-rate dissociative reaction through direct numerical simulation of a hypersonic turbulent boundary at Mach 9.2 with an isothermal cold wall surface, computed using Park’s five-species air dissociation model. Three sets of calculations are conducted, including two sets with non-catalytic and catalytic wall surface conditions, and one set without chemical reaction. Results show that the involved endothermic reaction mainly affects the magnitude of mean temperature and its fluctuations, whereas it has a relatively slight influence on the velocity and wall surface statistics. Turbulence-chemistry interaction is analysed within the same probability density function (PDF) framework as Wang & Xu (2024 J. Fluid Mech. vol. 998, A1), which considers temperature and species compositions in sample space. We find that modelling only the PDF of temperature, with simple knowledge of the mean species concentrations, is sufficient to reasonably well close the turbulent reaction rates and heat absorption rates, except for quantitative errors in the reaction rate of atomic nitrogen. This finding avoids the need for a more complex multivariable PDF in closure and also eliminates the requirement to model species fluctuations in RANS. Assuming a log-normal distribution for temperature provides better results, owing to the strongly skewed temperature distribution near the wall surface. The dependence and sensitivity of the single model parameter, temperature skewness, are further investigated. It is shown that the accuracy of closure result is not highly sensitive to the exact skewness value, as long as a negative one within a relatively wide range is selected. The developed closure model is applied to a wall model with species balance equations, showing significant improvement over the laminar closure, while further closure modelling efforts in the atomic nitrogen are still needed to improve computation robustness.
Advocating more repressive law and order policies along the slogan ‘tough on crime, tough on the causes of crime’ in their election manifesto, Tony Blair in the United Kingdom and Gerhard Schröder in Germany were elected in the late 1990s. Once in power, however, only New Labour substantially toughened law and order policies, whereas the German Social Democrats did not change the legal status quo, to a similar extent, during their mandate. This article tackles this puzzle, arguing that the preferences of the ministers and the formal and informal rules shaping the balance of power in government are crucial to understanding why two governments that initially advocated similar policies adopted a rather different policy stance. The results are based on meticulous process tracing and a series of elite interviews concerning two major topics in the realm of law and order during the 1990s: policies directed at sexual offenders, and policies responding to the terrorist attacks of 9/11.
The number of constitutional courts and supreme courts with constitutional review rights has strongly increased with the third wave of democratisation across the world as an important element of the new constitutionalism. These courts play an important role in day‐to‐day politics as they can nullify acts of parliament and thus prevent or reverse a change in the status quo. In macro‐concepts of comparative politics, their role is unclear. Either they are integrated as counter‐majoritarian institutional features of a political system or they are entirely ignored: some authors do not discuss their potential impact at all, while others dismiss them because they believe their preferences as veto players are entirely absorbed by other actors in the political system. However, we know little about the conditions and variables that determine them as being counter‐majoritarian or veto players. This article employs the concept of Tsebelis’ veto player theory to analyse the question. It focuses on the spatial configuration of veto players in the legislative process and then adds the court as an additional player to find out if it is absorbed in the pareto‐efficient set of the existing players or not. A court which is absorbed by other veto players should not in theory veto new legislation. It is argued in this article that courts are conditional veto players. Their veto is dependent on three variables: the ideological composition of the court; the pattern of government control; and the legislative procedures. To empirically support the analysis, data from the United States, France and Germany from 1974 to 2009 is used. This case selection increases variance with regard to system types and court types. The main finding is that courts are not always absorbed as veto players: during the period of analysis, absorption varies between 11 and 71 per cent in the three systems. Furthermore, the pattern of absorption is specific in each country due to government control, court majority and legislative procedure. Therefore, it can be concluded that they are conditional veto players. The findings have at least two implications. First, constitutional courts and supreme courts with judicial review rights should be systematically included in veto player analysis of political systems and not left aside. Any concept ignoring such courts may lead to invalid results, and any concept that counts such courts merely as an institutional feature may lead to distorted results that over‐ or under‐estimate their impact. Second, the findings also have implications for the study of judicial politics. The main bulk of literature in this area is concerned with auto‐limitation, the so‐called ‘self‐restraint’ of the government to avoid defeat at the court. This auto‐limitation, however, should only occur if a court is not absorbed. However, vetoes observed when the court is absorbed might be explained by strategic behaviour among judges engaging in selective defection.
The literature on party system nationalisation has yet to provide a better understanding of the impact of short‐term factors upon the nationalisation of politics. This article helps to fill this literature gap by analysing the effect of economic conditions on party system nationalisation. The argument is that economic crises will decrease levels of nationalisation by amplifying territorial variation in preferences for redistribution, limiting political parties’ capacity to coordinate divergent interests across districts and triggering the emergence of new political forces. Data on 47 countries for the 1960–2011 period confirm this hypothesis and show that lower economic growth during the years prior to the election is associated with a decrease in levels of party system nationalisation in the next election. The result is robust to variation in the specification of the econometric model and to the use of different measures of nationalisation. Results also show that federal institutions increase the impact of economic conditions on the nationalisation of politics, whereas any moderating effect of electoral system proportionality on the economy is not found.
While left and right are the main terms to distinguish political views in Western Europe, the family socialization of citizens has mainly been studied in terms of partisan preferences rather than identification with these ideological blocks. Therefore, this study investigates the intergenerational transmission of left-right ideological positions in two European multiparty systems. To investigate expectations regarding gendered patterns in political socialization, ideological transmission between mothers, fathers, daughters and sons are analyzed, making use of German and Swiss household data. The results underline the relevance of the family in the transmission of political ideology in multiparty systems, showing high contemporary parent–child concordance in ideological positioning in line with classic work in political socialization. Moreover, the study demonstrates how the gender-generation gap in political ideology is consequential for this process. Young women consistently place themselves on the left of men across all combinations of parental ideology, which indicates that the gender-generation gap trumps other gendered patterns in intergenerational transmission. Consequently, daughters are less likely than sons to take over their parents’ rightist positions, while parent–son transmission is equally large on the left and the right. This also means that left-leaning parents have a general advantage over right-leaning parents in having their ideological identification reproduced by their daughters. The study highlights the importance of differentiating between the transmission of left- and right-wing ideology in political socialization processes. Moreover, it demonstrates that the distinction by offspring gender is imperative when studying the intergenerational transmission of traits that display gender differences within and between parental and offspring generations. The findings point at the active role of especially female offspring in the political socialization process, as they seem to be more strongly impacted by influences outside the family that sustain generational processes of further gender realignment.
Having long shied away from proactively politicizing issues of European integration, the past crisis decade has put generally pro‐European mainstream parties under pressure to spell out more clearly which kind of Europe they support. We distinguish two such fundamental ideas of Europe: the redistributive polity, organizing transnational solidarity and the regulatory polity, strengthening national self‐reliance. Both notions are integrationist, but they come with distinct policy implications. What determines mainstream party support for either of these polity ideas? We investigate this question on data provided by the ‘EUandI’ voting advice application, which contains party positions on core issues of integration for all EU member states for the four European Parliament elections between 2009 and 2024. Mainstream party support for redistribution, we find, is generally driven by their ideological placement on the economic and cultural dimension. While progressive and left parties tend towards EU‐level redistribution, conservative and right parties are wedded to the idea of a regulatory European polity. This general dynamic, however, interacts with parties’ domestic considerations, that is, the public salience of an issue and a country's net‐payer status in the EU. We further find that the effect of mainstream parties’ ideological positioning differs across policy domains. While cultural and economic positions drive support for redistribution in fiscal and taxation policy to a nearly equal extent, support for redistribution in migration policy is driven by cultural factors alone, while in matters of security and defence right mainstream parties are more supportive of European solidarity than parties of the mainstream left. Our analysis demonstrates that mainstream parties now compete visibly over EU‐level redistribution, but that their stances on transnational solidarity differ depending on the domestic situation and the policy domain in question.
Scholars interested in legislative processes pay relatively little attention to the changes made to bills in parliamentary democracies. On the one hand, comparative research has often described parliamentary institutions as ineffectual vis‐à‐vis cabinets throughout the lawmaking process; on the other hand, for a long time the rational choice literature has focused more on the formal rules regulating amendatory activity than on amendatory activity itself. Hence, very few studies have tried to explain how much government bills are altered in parliament and why. This article investigates the changes made to governmental legislation in Italy. Taking the modifications occurring during the legislative process as the dependent variable, a number of explanatory hypotheses derived from both existing scholarship and original arguments are discussed and tested. This also allows the identification of some usually unobserved aspects of the decision‐making process within the cabinet. The findings can also be relevant for comparative research since Italy has been characterised during the period under scrutiny (1987–2006) by two distinct electoral systems, two extremely different party systems (pivotal and alternational), governments with various ideological orientations and range, and both partisan and technical ministers.
