ISO Standards Addressing Issues of Bias and Impartiality in Forensic Work

The ISO/IEC 17020 and 17025 standards both include requirements for impartiality and the freedom from bias. Meeting these requirements for implicit cognitive bias is not a simple matter. In this article, we address these international standards, specifically focusing on evaluating and mitigating the risk to impartiality, and quality assurance checks, so as to meet accreditation program requirements. We cover their meaning to management as well as to practitioners, addressing how these issues of impartiality and bias relate to forensic work, and how one can effectively evaluate and mitigate those risks. We then elaborate on specific quality assurance policies and checks and identify when corrective action may be appropriate. These measures will not only serve to meet ISO/IEC 17020 and 17025 requirements, but also enhance forensic work and decision-making.     

Do female legislators benefit from incumbency advantage? Incumbent renomination in a flexible-list PR system

This study investigates whether female legislators, just like their male colleagues, also benefit from incumbency advantage in the form of privileged access to candidate selection. This is done by examining whether female and male MPs receive the same reward for equivalent political performance when renomination decisions are made by political parties. Political performance is conceptualised in terms of incumbents’ popularity among voters, readiness to vote along the party line and legislative activity. An original dataset comprising 1032 observations on Czech legislators elected between 1996 and 2017 is used in the analysis. The results suggests that well-performing female MPs are just as likely as their male colleagues to secure a favourable renomination outcome. This result should not, however, be interpreted as evidence of gender-neutral access to re-election and political seniority as past research clearly indicates that female MPs need to work harder than men to produce the same political output.     

The more the better? Cumulative issue ownership and intra-campaign party switching

We contribute to the literature on short term changes in voters' party preferences (or intra-campaign party switching), by advancing a factor that has been neglected so far: Voters' perceptions about parties' issue competence. We develop a model of party switching that includes both classic predictors and issue ownership considerations. Moreover, in contrast to the usual single issue ownership conception focusing on the party deemed most competent to solve the most important problem, we argue that voters base their party choice on their perceptions of parties' competence on a variety of issues, i.e. on cumulative issue ownership. We test our model on panel data from the 2015 Swiss election study. The change in competence perceptions appears as a strong predictor of party switching: The higher the increase in the number of issues on which voters see a party as most competent during the campaign, the higher their likelihood to switch to that party.     

How post-imperial democracies die: A comparison of Weimar Germany and post-Soviet Russia

While socioeconomic crisis – like in Germany after World War I and in Russia after the Cold War – is a necessary precondition for democratic erosion resulting in a breakdown of democracy, it is not a sufficient condition. We identify, in the cases of Weimar Germany and post-Soviet Russia, a post-imperial syndrome that includes nationalist irredentism and an ambition to return to the status quo ante of a “great power” as a main reason why democratization faces specific and enormous challenges for former “great powers.” A slide back to authoritarianism in post-imperial democracies takes a high toll. It is facilitated by international political conflicts, including annexation and wars, with new neighbouring states that harbor territories perceived as external national homelands like the Sudetenland or Crimea.     

Internet voting and turnout: Evidence from Switzerland

Internet voting (i-voting) is often discussed as a potential remedy against declining turnout rates. This paper presents new evidence on the causal effect of i-voting on turnout, drawing on trials conducted in two Swiss cantons: Geneva and Zurich. Both Geneva and Zurich constitute hard cases for i-voting, given that i-voting was introduced in the presence of postal voting. However, this setting allows us to test some of the more optimistic claims regarding i-voting's ability to increase turnout. Empirically, we exploit the advantageous circumstance that federal legislation created a situation coming close to a natural experiment, with some of Geneva's and Zurich's municipalities participating in i-voting trials and others not. Using difference-in-differences estimation, we find that i-voting did not increase turnout in the cantons of Geneva and Zurich.     

Neighborhood heterogeneity and electoral turnout

We perform an empirical analysis to investigate how neighborhood heterogeneity affects electoral turnout. To this end, we rely on a unique dataset on local elections in an Italian municipality, which merges information on socio-economic characteristics of about 370.000 individuals with turnout data for 434 electoral precincts in 2004 and 2009. Exploiting both across and within precincts variation, we are able to disentangle the contextual effects on precinct-level electoral turnout of two different dimensions of neighborhood heterogeneity: income inequality and ethnic composition. Our results support the idea that contextual heterogeneity negatively affects political participation.     

Designing preference voting

Electoral systems in which voters can cast preference votes for individual candidates within a party list are increasingly popular. To the best of our knowledge, there is no research on whether and how the scale used to evaluate candidates can affect electoral behavior and results. In this paper, we analyze data from an original voting experiment leveraging real-life political preferences and embedded in a nationally representative online survey in Austria. We show that the scale used by voters to evaluate candidates makes differences. For example, the possibility to give up to two points advantages male candidates because male voters are more likely to give ‘zero points’ to female candidates. Yet this pattern does not exist in the system in which voters can give positive and negative points because male voters seem reluctant to actively withdraw points from female candidates. We thus encourage constitution makers to think carefully about the design of preference voting.     

Income-based voting and polarization over redistribution under alternative electoral systems

Democracies that have proportional electoral systems spend substantively more on welfare policies than those that have majoritarian systems. Theoretical accounts of this empirical regularity are generally tested using macro-level data, leaving micro-level implications untested. In this paper, I take an alternative approach, leveraging the fact that the theories in question make predictions about the electoral coordination between parties and voters around broad-based redistribution under alternative institutional arrangements. To test the theories, I create a novel measure of income-based voting, which captures the sensitivity of vote choice to changes in income and forms the dependent variable in a second stage model. Overall, I find robust support for more proportionality leading to more income-based voting.     

Ethnicity and electoral manipulation in Russia

To what extent does electoral manipulation follow ethnic lines in Russia? Using an original dataset based on raion-level data, we find that the “ethnic component” of electoral manipulation is more nuanced than previous studies have suggested. Electoral manipulation was most prevalent in majority-minority raions across ethnic and non-ethnic as well as richer and poorer regions. We argue that concentrations of ethnic minorities provide: (1) greater incentives for electoral manipulation by the central state and regional elites in order to signal political dominance and (2) greater capacity to carry out electoral manipulation through networks of local co-ethnic elites. However, multilevel analyses suggest that the extent of electoral manipulation was also strongly contingent on regional context. Electoral manipulation was significantly higher in the more politically volatile Muslim regions, while socioeconomic differences among regions, by contrast, had no discernible effect.     

Does district magnitude matter? The case of Taiwan

A sizable literature on electoral institutions argues that proportional electoral rules lead to higher voter turnout. However, recent work finds little evidence that the effect generalizes beyond western Europe and suggests that the theoretical arguments in the literature remain sparse, incomplete, and contradictory. I use a well-chosen data set to resolve the problem of omitted variable bias and Bayesian model averaging to address model uncertainty. I use Bayes factors to evaluate evidence both for and against the null hypotheses and find that the proportionality of electoral rules exerts no meaningful effect on turnout or any of the theoretical mechanisms I test.
