A Choice Set Modeling Approach to EU Issue Voting

Focusing on the case of Britain, this paper evaluates the role that EU issue voting played in the 1992 and 1997 elections. EU issue voting arises when the issue of European integration has a direct in uence on vote choice by in uencing the attractiveness of party alternatives. In this paper, we explore two different ways in which such infleunce can occur: elimination of party alternatives due to their EU stance or moderator of the utility felt toward a subset of party alternatives that are all viable for the voter. These two in uences are explored through a choice set logistic regression model. The results suggest that EU issue voting increased from 1992 to 1997, especially in England. However, compared with traditional left-right issues, the influence of EU issue voting remained modest even in 1997, when public opinion had taken a Euroskeptic turn and when the Conservative party was seen as much closer than Labour on this issue

The comparative meaning of political space: a comprehensive modeling approach

In latent scaling applications, such as the positioning of political parties, differential item functioning (DIF) may occur because of measurement issues or because of substantive differences in the association between latent and manifest variables. While the first source of DIF has received considerable attention, the second has not, although it is of potential interest to comparative scholars. In this research note, we introduce a novel hierarchical Bayesian item response model that allows us to disentangle different sources of DIF. Drawing on the 2019 Chapel Hill Expert Survey (CHES), we highlight how the same issues are unequally politicized across Western Europe, and how some issues are less ideologically determined than others. Our model can be adapted to alternate settings, allowing researchers to shine a light on variation in, e.g., ideology, issue politicization, or party competition

Deliberative inclusion of minorities: patterns of reciprocity among linguistic groups in Switzerland

We present a model of deliberative inclusion, focusing on reciprocity in the interaction between structural minorities/disadvantaged groups and majorities/privileged groups. Our model, however, comes with a ‘friendly amendment': we have put the ‘burden of reciprocity' mainly on majorities and privileged groups. It is mainly their obligation to seriously listen and respond to the demands and arguments of minorities and disadvantaged groups and show a willingness to respect and accommodate these interests. Empirically, we apply our model to the interaction of linguistic groups in the Swiss parliament. We find a highly egalitarian, sometimes even minority-favoring mode of interaction between the German-speaking majority and linguistic minorities. The German-speaking majority seems to be willing to take the ‘burden of reciprocity' when linguistic minorities' vital interests are concerned. Conversely, linguistic minorities are slightly more self-referential and adversarial under such condition

Identity Formation between Structure and Agency – How ‘Us’ and ‘Them’ Relates to Voting Behavior in Contexts of Electoral Realignment

Western Europe is experiencing growing levels of political polarization between parties of the New Left and the Far Right. In many countries, the socio-structural foundations of this divide (class, education, residence) are by now so clear that many interpret this divide as a fully mobilized new electoral cleavage. At the same time, observers have highlighted a growing fragmentation of party systems and the proliferation of new competitors. We suggest to make sense of these contradic- tory developments by focusing on the shared group identities that constitute the “glue” of cleavage formation translating grievances into political antagonisms. Our contribution relies on data from an original online survey fielded in France, Germany, the UK and Switzerland. Respondents an- swered questions on their sense of belonging to a series of social groups, electoral preferences and socio-demographics. On this basis, we are able to show – observationally – that socio-structural categories relate to both socio-economically (e.g. class) and socio-culturally (e.g. cosmopolitanism, lifestyle) connoted group identities, which divide New Left and Far Right voters in surprisingly similar ways across contexts. We then study the extent of social closure and political mobilization at the extremes of the new divide through the analysis of social networks, perceived group align- ments, and perceived representation. Our findings suggest that the new conflict is firmly rooted in socio-economic categories and at the societal level. Its political mobilization happens mostly via culturally connoted identities. What is more, social realignments and closure are highly similar across the four countries. This underscores that party competition remains rooted in structural an- tagonisms even as support for individual parties becomes more volatile. To detect this underlying similarity and stability, it is necessary to focus on voter alignments to ideological party blocs, rather than individual parties

Measuring Political Deliberation: A Discourse Quality Index

In this paper, we develop a discourse quality index (DQI) that serves as a quantitative measure of discourse in deliberation. The DQI is rooted in Habermas' discourse ethics and provides an accurate representation of the most important principles underlying deliberation. At the same time, the DQI can be shown to be a reliable measurement instrument due to its focus on observable behavior and its detailed coding instructions. We illustrate the DQI for a parliamentary debate in the British House of Commons. We show that the DQI yields reliable data and we discuss how these data could be used in subsequent analysis. We conclude by discussing some limitations of the DQI and by identifying some areas in which it could prove useful. Introduction Over the past decade, deliberative politics has moved to the forefront of political theory. 1 Deliberation implies that political decision-making is or should be 'talk-centric' rather than 'vote-centric Despite the advances in the political theory of deliberation and despite deliberative theorists' claims about the importance of discourse, empirically 2 This is partially a reflection of the continued predominance of social choice theory and other theories that treat preferences as given and view decision-making as a process of preference aggregation. However, a larger issue may be the dearth of measurement instruments that allow researchers to operationalize and quantify the quality of discourse, and that open up deliberation for empirical research. In this article, we develop a measurement instrument of deliberative quality -the discourse quality index (DQI). This measurement instrument has the advantage that it is theoretically grounded, finding its origins in Habermas (1981, 1990, 1991, 1992, 1995, 1996) as well as other theorists. At the same time, the DQI can be applied easily and reliably to a wide range of deliberative contexts. Thus, the DQI opens up deliberation for empirical research, allowing this research to interface with political theory. We should point out at the outset that this is a measurement paper. We lack the space to investigate actually the impact of discourse quality on political outcomes. Although many theorists believe that deliberative politics leads to better outcomes, there is no consensus on this matter, with some arguing vociferously that an automatic connection between deliberation and just outcomes cannot be presumed We organize this article as follows. First, we discuss the criteria that a measure of the nature of discourse should satisfy. Next, we discuss two past efforts at measuring deliberation. Third, we discuss the theoretical foundation of the DQI. Having laid the groundwork, we then provide a detailed discussion of the DQI. This is followed by an empirical illustration that shows the coding procedures as well as the measurement properties of the DQI. We then discuss how the DQI can be employed in empirical research. We conclude by discussing some limitations of the DQI and opportunities for its use. Measurement Criteria A measure of the nature of discourse can serve as a bridge between political theory and empirical scholarship only if it does justice to the former and provides guidance to the latter. We believe, therefore, that such a measure should meet four different criteria: (1) it should be theoretically grounded, (2) it should tap into observable phenomena, (3) it should be general, and (4) it should be reliable. The first criterion is essential because it concerns the validity of the discourse measure. An improperly grounded measure lacks construct validity, would be of little practical use and would fail to convince theorists. The complication here is the lack of agreement among political theorists about what constitute deliberation and discourse. One could attempt to develop a measure that captures all of the different conceptions of these concepts, but this would result in an instrument that is too complex to be of practical value and one that lacks internal consistency (since the different theories are not necessarily compatible). Our approach is different; we have selected a particular theory of deliberation, one that is most closely associated with The second to fourth criteria speak to the empirical power of a discourse measure. Most importantly, the measurement instrument should tap into observable discourse behavior. This is essential if the measurement instrument is to produce reliable data and if it is to convince empirical scholars. In addition, an ideal measure of discourse quality should be general, so that it can be transported from one research domain to the next. Finally, such a measure should be reliable. This requires not only that it is based on observable behavior, but also that its coding instructions are specific, and that its coding categories are sufficiently clear that different coders could agree on the classification of the same discourse. Of course, reliable measurement is never guaranteed, so that empirical reliability assessments should be a standard practice in discourse analysis. Below, we shall argue that the DQI meets these criteria. However, before outlining the logic of this measure, we should review past efforts at measuring discourse. As we shall see, these efforts leave considerable room for improvement

Who's Cueing Whom? Mass-elite linkages and the future of European integration

The 2005 French and Dutch referendum campaigns were characterized by an alleged disconnect between pro-European political elites and Eurosceptic masses. Past evidence regarding elite-mass linkages in the context of European integration has been conflicting. Whereas some scholars argue that political elites respond to the changing preferences of their electorates, others suggest that party elites cue the mass public through a process of information and persuasion. We contend that these conflicting results stem from the reciprocal nature of elite-mass linkages and estimate a series of dynamic simultaneous equations models to account for this reverse causation. Using Euro-barometer and expert survey data from 1984-2002, we find evidence of a dual-process model, whereby party elites both respond to and shape the views of their supporters. We also find that the strength of these results is contingent on several factors, including the type of electoral system, intra-party dissent and voter characteristics.

Pupil dilation reveals top–down attentional load during spatial monitoring

It has long been known that the diameter of human pupil enlarges with increasing effort during the execution of a task. This has been observed not only for purely mechanical effort but also for mental effort, as for example the computation of arithmetic problems with different levels of difficulty. Here we show that pupil dilation reflects changes in visuospatial awareness induced by attentional load during multi-tasking. In the single-task condition, participants had to report the position of lateralized, briefly presented, masked visual targets ("right", "left", or "both" sides). In the multitasking conditions, participants also performed additional tasks, either visual or auditory, to increase the attentional load. Sensory stimulation was kept constant across all conditions to rule out the influence of low-level factors. Results show that event-related pupil dilation strikingly increased with task demands, mirroring a concurrent decrease in visuospatial awareness. Importantly, pupil dilation significantly differed between two dual-task conditions that required to process the same number of stimuli but yielded differed levels of accuracy (difficulty). In contrast, pupil dilation did not differ between two conditions which were equally challenging but differed both in the modality of the dual task (auditory vs. visual) and in the number of stimuli to be attended. We conclude that pupil dilation genuinely reflects the top-down allocation of supramodal attentional resources

Active behaviour during early development shapes glucocorticoid reactivity

TGlucocorticoids are the final effectors of the stress axis, with numerous targets in the central nervous system and the periphery. They are essential for adaptation, yet currently it is unclear how early life events program the glucocorticoid response to stress. Here we provide evidence that involuntary swimming at early developmental stages can reconfigure the cortisol response to homotypic and heterotypic stress in larval zebrafish (Danio rerio), also reducing startle reactivity and increasing spontaneous activity as well as energy efficiency during active behaviour. Collectively, these data identify a role of the genetically malleable zebrafish for linking early life stress with glucocorticoid function in later life

International Society of Sports Nutrition Position Stand: Probiotics.

Position statement: The International Society of Sports Nutrition (ISSN) provides an objective and critical review of the mechanisms and use of probiotic supplementation to optimize the health, performance, and recovery of athletes. Based on the current available literature, the conclusions of the ISSN are as follows: 1)Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host (FAO/WHO).2)Probiotic administration has been linked to a multitude of health benefits, with gut and immune health being the most researched applications.3)Despite the existence of shared, core mechanisms for probiotic function, health benefits of probiotics are strain- and dose-dependent.4)Athletes have varying gut microbiota compositions that appear to reflect the activity level of the host in comparison to sedentary people, with the differences linked primarily to the volume of exercise and amount of protein consumption. Whether differences in gut microbiota composition affect probiotic efficacy is unknown.5)The main function of the gut is to digest food and absorb nutrients. In athletic populations, certain probiotics strains can increase absorption of key nutrients such as amino acids from protein, and affect the pharmacology and physiological properties of multiple food components.6)Immune depression in athletes worsens with excessive training load, psychological stress, disturbed sleep, and environmental extremes, all of which can contribute to an increased risk of respiratory tract infections. In certain situations, including exposure to crowds, foreign travel and poor hygiene at home, and training or competition venues, athletes' exposure to pathogens may be elevated leading to increased rates of infections. Approximately 70% of the immune system is located in the gut and probiotic supplementation has been shown to promote a healthy immune response. In an athletic population, specific probiotic strains can reduce the number of episodes, severity and duration of upper respiratory tract infections.7)Intense, prolonged exercise, especially in the heat, has been shown to increase gut permeability which potentially can result in systemic toxemia. Specific probiotic strains can improve the integrity of the gut-barrier function in athletes.8)Administration of selected anti-inflammatory probiotic strains have been linked to improved recovery from muscle-damaging exercise.9)The minimal effective dose and method of administration (potency per serving, single vs. split dose, delivery form) of a specific probiotic strain depends on validation studies for this particular strain. Products that contain probiotics must include the genus, species, and strain of each live microorganism on its label as well as the total estimated quantity of each probiotic strain at the end of the product's shelf life, as measured by colony forming units (CFU) or live cells.10)Preclinical and early human research has shown potential probiotic benefits relevant to an athletic population that include improved body composition and lean body mass, normalizing age-related declines in testosterone levels, reductions in cortisol levels indicating improved responses to a physical or mental stressor, reduction of exercise-induced lactate, and increased neurotransmitter synthesis, cognition and mood. However, these potential benefits require validation in more rigorous human studies and in an athletic population
