Party convergence and vote switching: Explaining mainstream party decline across Europe

How can one explain the significant vote losses of mainstream parties across Europe in recent years? In this article, it is argued that mainstream party convergence is an important determinant of the recent political and electoral volatility in European party systems. More specifically, it is hypothesised that as mainstream parties converge on the left-right scale, voters will switch from supporting a mainstream party to a non-mainstream party in the next election as they look for an alternative that better represents their ideological views. To test these theoretical expectations, data is combined from the Comparative Study of Electoral Systems and the Manifestos Project for nearly 15,000 vote choices of individual voters in 30 elections in 16 West and East European countries from 2001 until 2013. The findings have important implications for understanding the recent rise of non-mainstream parties, the changing nature of party systems and the increasing complexity of cabinet formation across Europe.     

Characterization of pyrotechnic reaction residue particles by SEM/EDS

Today the method commonly used for detecting gunshot residue is through the combined use of scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). In recent years, this same methodology began to find use in detecting and characterizing pyrotechnic reaction residue (PRR) particles whether produced by explosion or burning. This is accomplished by collecting particulate samples from a surface in the immediate area of the pyrotechnic reaction. Suspect PRR particles are identified by their morphology (typically 1 to 20 microm spheroidal particles) using an SEM; then they are analyzed for the elements they contain using X-ray EDS. This can help to identify the general type of pyrotechnic composition involved.     

Organised interests in the media and policy congruence: The contingent impact of the status quo

While a multitude of studies have investigated the link between opinion and policy, we have little knowledge of how and when organised interests affect this linkage. We argue that the alignment of organised interests affects opinion–policy congruence by influencing the weight decision-makers attach to citizen preferences. Moreover, we propose that alignment between majorities of groups and the public matters the most when status quo bias must be overcome for the public to obtain its preferred policy. We test our theoretical claims drawing on a comprehensive media content analysis of 160 policy issues in Germany and Denmark. Our results present a more sceptical picture of the ability of groups to suppress the opinion–policy linkage than the one frequently presented in the academic literature and public debate. We find that the capacity of groups to affect whether policy is congruent with the majority of the public is restricted to situations where the public supports a change in the status quo. In these cases, policy is less likely to end up reflecting public opinion if the majority of interest groups do not support the public position. In cases where the public is supportive of the policy status quo, the position of interest groups does not affect the likelihood that policy will eventually reflect the preferred position of the public. Our findings expand existing knowledge of organised interests in the study of policy representation and have important implications for understanding democratic governance.     

Pyrotechnic reaction residue particle analysis

Pyrotechnic reaction residue particle (PRRP) production, sampling and analysis are all very similar to that for primer gunshot residue. In both cases, the preferred method of analysis uses scanning electron microscopy to locate suspect particles and then uses energy dispersive x-ray spectroscopy to characterize the particle's constituent chemical elements. There are relatively few times when standard micro-analytical chemistry performed on pyrotechnic residues may not provide sufficient information for forensic investigators. However, on those occasions, PRRP analysis provides a greatly improved ability to discriminate between materials of pyrotechnic origin and other unrelated substances also present. The greater specificity of PRRP analysis is the result of its analyzing a large number of individual micron-sized particles, rather than producing only a single integrated result such as produced using standard micro-analytical chemistry. For example, PRRP analyses are used to demonstrate its ability to successfully (1) discriminate between pyrotechnic residues and unrelated background contamination, (2) identify that two different pyrotechnic compositions had previously been exploded within the same device, and (3) establish the chronology of an incident involving two separate and closely occurring explosions.     

Does anybody notice? How policy positions of coalition parties are perceived by voters

Does governing in coalitions affect how coalition parties’ policy positions are perceived by voters? In this article, the authors seek to understand the relationship between parties’ participation in coalition governments and their perception by voters. Policy positions are an important instrument through which parties compete for the support of voters. However, it is unclear to what extent voters can correctly perceive the positions of parties when they govern together with other coalition partners. It is argued here that because of the blurred lines of responsibility in multiparty cabinets, it is difficult for voters to correctly perceive the positions of coalition parties. What is more, it is expected that the internal functioning of coalition cabinets affects the extent to which coalition parties struggle to get their message out to voters. It is hypothesized in the article that intra‐cabinet conflict is negatively related to misperception. To test their theoretical expectations, the authors combine data on the left‐right policy positions of political parties from the Comparative Manifestos Project with data on how these positions are perceived by voters gathered from the Comparative Study of Electoral Systems from 1996 to 2011. The findings shed light on the relationship between party competition and coalition governments, and its implications for political representation.
