Alcohol and Violence Related Cognitive Risk Factors Associated with the Perpetration of Intimate Partner Violence

The primary aim of this study is to determine the association between alcohol, violence related cognitive risk factors, and impulsivity with the perpetration of partner violence among current drinkers. A probability sample (n = 1468) of White, Black, and Hispanic couples 18 years of age or older in the United States household population was interviewed in 1995 with a response rate of 85%. The risk factors of interest included the alcohol and violence related cognitions of approval of marital aggression, alcohol as an excuse for misbehavior, and aggressive expectations following alcohol consumption as well as impulsivity. In all, 15% (216/1468) of the respondents reported perpetration of domestic violence. In addition, 24% (7/29) of those who approved of marital violence, 11% (126/1163) of those who reported alcohol use as an excuse for misbehavior, 10% (128/1257) of those who reported aggressive expectations following alcohol consumption, and 14% (99/716) of those who reported impulsivity also reported perpetration of domestic violence. Bivariate analysis indicated that all of the cognitive risk factors were significantly more common in those who reported perpetration of intimate partner violence (IPV) (p < 0.05). However, multivariate analysis controlling for ethnicity, education, income, age, gender, and impulsivity indicated that those who reported strong or very strong expectations of aggressive behavior following alcohol consumption were 3.2 (95% CI = 1.3–7.9) times more likely to perpetrate IPV. Although all of the alcohol and violence related cognitive risk factors were associated with the perpetration of domestic violence, expectations of aggressive behavior following alcohol consumption appeared to be the strongest predictor of the perpetration of IPV among current drinkers. Therefore, alcohol expectancy may be an important factor to assess when attempting to identify and treat perpetrators of domestic violence who are also current drinkers.     

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.
