Genetic structure among 38 populations from the United States based on 11 U.S. core Y chromosome STRs

A DNA database consisting of the 11 Y chromosome short-tandem-repeat (Y-STR) recommended by the Scientific Working Group on DNA Analysis Methods is constructed for 2517 individuals from 38 populations in the United States. The population samples derive from five ethnic groups currently living in 10 states. A multidimensional scaling (MDS) plot places the populations into four discrete clusters (African Americans (AA), European Americans (EA), Hispanic Americans (HA), and Asian Americans (SA)) and one dispersed cluster of Native Americans. An analysis of molecular variance (AMOVA) indicates that a large proportion of the total genetic variance is partitioned among ethnic groups (24.8%), whereas only a small amount (1.5%) is found among-populations within ethnic groups. Separate AMOVA analyses within each ethnic group show that only the NA sample contains statistically significant among-population variation. Pair wise population differentiation tests do uncover heterogeneity among EA and among HA populations; however, this is due to only a single sample within each group. The analyses support the creation of AA, EA, HA, and Asian American databases in which samples from different geographic regions within the United States are pooled. We recommend that separate databases be constructed for different NA groups.     

Provider medicaid fraud: A note on white-coat crime

To date, relatively few empirical studies have been conducted of provider medicaid fraud or, more generally, of “white-coat crime”--offenses by health professionals. Based on data accumulated by a quality control unit on the duplicate billings for a single service by New York State providers, the present research attempts to help fill this void by assessing the prevalence of medicaid fraud. Two conclusions are suggested by the data. First, unlike other realms of upperworld criminality, provider fraud does not appear to be pervasive. Second, provider occupations with more of a business orientation appear to have a greater involvement in fraudulent activities than groups that are more fully professionalized.     

Party organizational development and the electoral performance of the radical right: exploring the role of local candidates in the breakthrough elections of the Sweden democrats 2002–2014

It is today commonplace to view radical right parties as masters of their own fates. However, whereas most authors in the field focus on dominant leaders, the impact of party organizations remains understudied. To remedy some of this, we study the impact of three unique measures of organizational development on the electoral performance of the Sweden Democrats (SD) in four consecutive local elections between 2002 and 2014. When controlling for crucial demand- and supply-side factors, while holding the appeal of the national leadership constant, we find that the size, competence, and stability of the local candidate base were all decisive for explaining the success of the SD. These findings suggest that a developed organizational base not only matters to the long-term persistence of radical right parties, but also to their electoral breakthrough. Additionally, we suggest that party organizations are likely to have a greater impact in countries where radical right parties are already established. We conclude by arguing that our findings potentially provide insights into mechanisms that explain how new parties in general establish themselves.
