Breathalyzer accuracy in actual law enforcement practice: a comparison of blood- and breath-alcohol results in Wisconsin drivers

Breathalyzer and blood-alcohol results from drivers arrested for operating a motor vehicle while intoxicated and for related offenses were compared during a two-year period. Four hundred and four pairs of breath- and blood-alcohol results from specimens collected within 1 h of each other were studied. Blood-alcohol concentrations ranged from zero to 0.421% weight per volume (w/v). Breath-alcohol concentrations ranged from zero to 0.44 g/210 L. The mean Breathalyzer result was 0.16 g/210 L. The mean blood-alcohol result was 0.176% w/v. Compared to the blood-alcohol result, Breathalyzer results were lower by more than 0.01 g/210 L 61% of the time, within 0.01 g/210 L 33% of the time, and higher by more than 0.01 g/210 L 6% of the time.     

The Evolution of Substate Nationalist Parties as Statewide Parliamentary Actors: CiU and PNV in Spain

This contribution examines party competition between the Catalan Convergence and Union (CiU) and the Basque Nationalist Party (PNV), two substate nationalist parties, and the statewide governing party based on the degree to which they ally in Spain's statewide parliament. It demonstrates that party competition during statewide minority governments is quite cooperative, though with variation, and statewide majority governments are associated with less cooperation. The weight of properiphery stances in the nationalist parties’ manifestos does not explain the patterns of party competition. In part, their behavior is associated with opportunities to influence policy and interparty competition in their respective regions.
