Belgian canine population and purebred study for forensics by improved mitochondrial DNA sequencing

In canine population studies for forensics, the mitochondrial DNA is profiled by sequencing the two hyper variable regions, HV1 and HV2 of the control region.In a first effort to create a Belgian population database some samples showed partially poor sequence quality. We demonstrated that a nuclear pseudogene was co-amplified with the mtDNA control region. Using a new combination of primers this adverse result was no longer observed and sequencing quality was improved. All former samples with poor sequence data were reanalyzed. Furthermore, the forensic canine population study was extended to 208 breed and mixed dogs. In total, 58 haplotypes were identified, resulting in an exclusion capacity of 0.92. The profile distribution of the Belgian population sample was not significantly different from those observed in population studies of three other countries.In addition to the total population study 107 Belgian registered pedigree dogs of six breeds were profiled. Per breed, the obtained haplotypes were supplemented with those from population and purebred studies. The combined data revealed that some haplotypes were more or less prominent present in particular dog breeds. The statistically significant differences in haplotype distribution between breeds and population sample can have consequences on mtDNA databasing and matching probabilities in forensics.     

Threat, Anxiety, and Support of Antiterrorism Policies

The perception of threat and the experience of anxiety are distinct but related public reactions to terrorism. Anxiety increases risk aversion, potentially undercutting support for dangerous military action, consistent with terrorists' typical aims. Conversely, perceived threat increases a desire for retaliation and promotes animosity toward a threatening enemy, in line with the usual goals of affected governments. Findings from a national telephone survey confirm the differing political effects of anxiety and perceived threat. The minority of Americans who experienced high levels of anxiety in response to the September 11 attacks were less supportive of aggressive military action against terrorists, less approving of President Bush, and favored increased American isolationism. In contrast, the majority of Americans who perceived a high threat of future terrorism in the United States (but were not overly anxious) supported the Bush administration's antiterrorism policies domestically and internationally.     

Racial Resentment and White Opposition to Race‐Conscious Programs: Principles or Prejudice?

White racial resentment is associated with opposition to a broad range of racial policies but it is unclear whether it derives from racial prejudice or stems from ideological principles. To resolve this ambiguity, we examined the impact of racial resentment on support for a college-scholarship program in which program beneficiaries' race and socioeconomic class was experimentally varied. The analyses yield a potentially troubling finding: racial resentment means different things to white liberals and conservatives. Among liberals, racial resentment conveys the political effects of racial prejudice, by predicting program support for black but not white students, and is better predicted by overt measures of racial prejudice than among conservatives. Among conservatives, racial resentment appears more ideological. It is closely tied to opposition to race-conscious programs regardless of recipient race and is only weakly tied to measures of overt prejudice. Racial resentment, therefore, is not a clear-cut measure of racial prejudice for all Americans.     

Measuring Partisanship as a Social Identity in Multi-Party Systems

There is no doubt that partisanship is a powerful influence on democratic political behavior. But there is also a lively debate on its nature and origins: Is it largely instrumental in nature and shaped by party performance and issues stances? Or is it basically a long-standing expressive identity reinforced by motivated reasoning and strong emotions? We assess the nature of partisanship in the European context, examining the measurement properties and predictive validity of a multi-item partisan identity scale included in national surveys conducted in the Netherlands, Sweden, and the U.K. Using a latent variable model, we show that an eight-item partisan identity scale provides greater information about partisan intensity than a standard single-item and has the same measurement properties across the three countries. In addition, the identity scale better predicts in-party voting and political participation than a measure of ideological intensity (based on both left–right self-placement and agreement with the party on key issues), providing support for an expressive approach to partisanship in several European democracies.     

The Effect of Interviewer Gender on the Survey Response

We examined the existence of gender-of-interviewer effects in two local-area surveys in which male and female interviewers were randomly assigned to interview male and female respondents. Small but consistent gender-of-interviewer effects arose on questions related to the women's movement, women's issues, and gender equality, demonstrating that, as expected, respondents were more likely to provide feminist answers to female interviewers. Gender-of-interviewer effects were somewhat more pronounced and consistent on controversial political topics: the women's movement (feminists and political activism) and their policy agenda. There was mixed evidence on whether respondents were equally susceptible to gender-of-interviewer effects. In one of the surveys, gender-of-interviewer effects were more pronounced among less well-educated and younger respondents than among respondents who were better educated or older. This effect was not replicated in the second survey.
