This article uses state-level data on cirrhosis death ratesto examine the impact of state prohibitions, pre-1920 federalantialcohol policies, and constitutional prohibition on cirrhosis.State prohibitions had a minimal impact on cirrhosis, especiallyduring the pre-1920 period. Pre-1920 federal antialcohol policiesmay have contributed to the decline in cirrhosis that occurredbefore 1920, although other factors were likely substantialinfluences as well. Constitutional Prohibition reduced cirrhosisby about 1020%. 相似文献

Jeffrey D. Wilson 《Asian Security》2018,14(3):358-373
In 2008, rare earth minerals (REMs) shot to the top of the international agenda. When China began restricting exports of these critical materials, many claimed it was threatening a “REMs weapon” against the US and Japan. Yet by 2014, the crisis had quickly abated, as China shelved its policies in the face of pressure from consumer governments. This article examines why REMs emerged – and then quickly disappeared – as a threat to international security in Asia. It first conceptualizes the geopolitics of critical materials, before analyzing the politics of the REMs crisis between Japan, China, and the US. It argues that China’s ability to use REMs for diplomatic coercion was inherently weak and is unlikely to pose a similar threat to international security in future years. 相似文献

In this study, we examined predictors of parenting during adolescence from three domains: the contextual (i.e., stress, support, marital satisfaction), social-cognitive (i.e., beliefs about adolescence), and child (difficulty). Fifty-three mothers and 38 fathers of 13–18 year olds were interviewed and rated on three dimensions of parenting—involvement, autonomy support, and structure. Parents completed questionnaires assessing predictor variables. Results indicated that, for mothers, higher numbers of recent stressful events were associated with less provision of structure and more control. For fathers, relations between views of adolescence and parenting were in evidence; while for both mothers and fathers strong relations between adolescent difficulty and parenting emerged. Relations between perceived difficulty of adolescent and parenting were more apparent in conducive than nonconducive contexts. The differential results for mothers and fathers are interpreted in terms of mothers' greater involvement and less role latitude than fathers. Parents' resources, experience, and expectations are considered in understanding why predictors might be associated with parenting variables.Received Ph.D. in clinical psychology from University of Rochester.

Using 35 variables and discriminant analysis procedures, it was found that, of 133 male defendants entering the insanity plea in Colorado, 87 percent were classified correctly into the disposition groups "adjudicated insane" and "convicted." Most positively related to an insanity adjudication were a psychiatric evaluation of insanity and a diagnosis of schizophrenia. Negatively related to the insanity verdict were diagnoses of substance use and personality disorders. 相似文献
