Lawyers' Perceptions of the U.S. Supreme Court: Is the Court a “Political” Institution?

Do legal elites—lawyers admitted to federal appellate bars—perceive the Supreme Court as a “political” institution? Legal elites differentiate themselves from the mass public in the amount and sources of information about the Court. They also hold near‐universal perceptions of Court legitimacy, a result we use to derive competing theoretical expectations regarding the impact of ideological disagreement on various Court perceptions. Survey data show that many legal elites perceive the Court as political in its decision making, while a minority perceive the Court as activist and influenced by external political forces. Ideological disagreement with the Court's outputs significantly elevates political perceptions of decision making, while it exhibits a null and moderate impact on perceptions of activism and external political influence, respectively. To justify negative affect derived from ideological disagreement, elites highlight the political aspects of the Court's decision making rather than engage in “global delegitimization” of the institution itself.     

Remembering to Forget: A Note on the Duration of Campaign Advertising Effects

Exposure to an Obama campaign ad as part of an Internet survey conducted during the final weeks of the 2012 presidential race produced a substantial 2.8-point increase in intentions to vote for Obama. A post-election follow-up survey found an increase in reported votes for Obama that was only half as large, consistent with the notion that ad effects decay over time. However, a closer look at the pattern of decay indicates that the effect of ad exposure remained virtually constant among people who were undecided or predisposed to support Obama. The reduced aggregate effect was almost entirely attributable to Romney supporters who moved toward Obama in the immediate wake of ad exposure but returned to Romney by Election Day. This divergence is inconsistent with an interpretation of decay as reflecting simple forgetting. Rather, it suggests an active process of motivated reasoning in which short-term persuasive effects are gradually eroded or even reversed by counterarguing among people predisposed to resist them.     

The dynamic properties of individual-level party identification in the United States

Central to traditionalist and revisionist perspectives of individual-level party identification is a debate about the stability of party identification. We revisit the debate about the dynamic properties and processes underlying party identification. We present a conceptual framework that defines heterogeneity and state dependence as endpoints of a continuum underlying partisan stability, which is important in understanding an individual’s capacity for updating partisanship. Using panel data from the 1992-1996 National Election Study, we estimate dynamic, random effects multinomial logit models of party identification that distinguish between heterogeneity and “true state dependence.” In accord with traditionalist perspectives, our evidence suggests that in general, minimal state dependence underlies party identification; party identification is strongly stationary. However, we find that age enhances the magnitude of state dependence, which provides some support for revisionist theories. Overall, our work showcases how explaining individual-level dynamics expands our knowledge of partisan stability.     

Beyond the Running Tally: Partisan Bias in Political Perceptions

I examine the impact of long-term partisan loyalties on perceptions of specific political figures and events. In contrast to the notion of partisanship as a simple running tally of political assessments, I show that party identification is a pervasive dynamic force shaping citizens' perceptions of, and reactions to, the political world. My analysis employs panel data to isolate the impact of partisan bias in the context of a Bayesian model of opinion change; I also present more straightforward evidence of contrasts in Democrats' and Republicans' perceptions of objective politically relevant events. I conclude that partisan bias in political perceptions plays a crucial role in perpetuating and reinforcing sharp differences in opinion between Democrats and Republicans. This conclusion handsomely validates the emphasis placed by the authors of The American Voter on the role of enduring partisan commitments in shaping attitudes toward political objects.     

“The Big Society,” Public Expenditure,and Volunteering

The debate on volunteering has paid insufficient attention to the relationship between public spending and volunteering. The importance of this relationship is highlighted by the British government's “Big Society” plan, which asserts that an increase in volunteering will compensate for the withdrawal of public agencies and spending. This idea is based on the widely held belief that a high degree of government intervention decreases voluntary activities. This article uses a multidisciplinary approach to improve understanding of how public spending affects the decision to volunteer. A theoretical model conceptualizes this relationship in terms of time donation by employed individuals. The model is tested empirically through an econometric analysis of two survey data sets and interpretative analysis of narratives of local volunteers and public professionals. The results suggest that volunteering is likely to decline when government intervention decreases and that a collaborative approach to sustaining volunteering is needed.     

The Nature of Legal Change on the U.S. Supreme Court: Jurisprudential Regimes Theory and Its Alternatives

Jurisprudential regimes theory (JRT) posits that legal change on the U.S. Supreme Court occurs in a drastic, structural‐break‐like manner. Methodological debates present conflicting evidence for JRT, which has implications for the important law versus ideology debate. We confront this debate by first elaborating two alternative theoretical perspectives to JRT—evolutionary change and legal stability. Our analytical framework focuses on two key substantive effects of jurisprudential categories on the Court's case outcomes—relative differences between categories over multiple time periods and longitudinal differences across time periods. Importantly, different pieces of empirical evidence can provide support for different dynamic processes. The extent to which “law matters” is not necessarily tied to one particular model of legal change. Empirical analysis of updated and backdated free expression data generates key findings consistent with JRT, legal stability, and evolutionary change. We discuss the implications of the results for understanding legal change and legal influence.     

LC-MS/MS analysis of pholedrine in a fatal intoxication case

Pholedrine (4'-hydroxymethamphetamine) is a cardiovascular agent exerting hypertensive and adrenergic effects. High doses may cause a drop in the peripheral circulation blood flow and increase blood pressure, heart rate and body temperature up to a state of central respiratory paralysis. A 15-year-old girl who suffered from heavy agitation and hallucinations was admitted to the intensive care unit in a comatose state. The clinical findings included a maximum heart rate of 170 bpm and a body temperature of 43.8 degrees C. Resuscitation measures were in vain and abandoned after approximately 2h. A toxicological emergency analysis using GC/MS revealed a considerable amount of pholedrine in blood and urine. A method for determining pholedrine in human body fluids utilizing high-performance liquid chromatography (HPLC)/tandem mass spectrometry (LC-MS/MS) with a turbo ion-spray source was developed, using D11-methamphetamine and D5-methylenedioxymethamphetamine as internal standards. Samples were prepared by SPE extraction using SPEC-C18AR/MP3((R)) columns, which yielded the best extraction recovery (67%). Chromatographic separation was achieved at pH 5 on an RP-18 stationary phase applying gradient elution from 50 to 70% of B (methanol/acetonitrile 3/1 (v/v), 0.02% acetic acid) in A (5mM ammonium acetate/acetonitrile 95/5 (v/v), 0.02% acetic acid). Supra-pure acetic acid was added to the post-column effluent with a flow rate of 0.2 microl/min to optimize ionization. Detection was carried out in the positive ionization, multiple reaction monitoring (MRM) mode. The chromatograms showed no interference from other substances. The limit of detection (LOD, S/N=3) of pholedrine was 0.8 ng/ml and its lower limit of quantification (LLOQ, S/N=10) 3ng/ml. The calibration curve was linear (r=0.999) in the range 1-100 ng/ml. Samples with higher concentrations were diluted to suit the working range. The intra-day R.S.D. between 5 and 80 ng/ml were 3.8-8.7% and the inter-day R.S.D. between 5 and 100 ng/ml were 6.7-10.7%. The pholedrine concentrations in blood and urine collected when the girl was still alive were 16.1 microg/ml (R.S.D. 10.5%) and 1120 microg/ml (R.S.D. 8%), respectively. In post-mortem samples, they were 23.0 microg/ml (R.S.D. 5.1%) in heart blood and 27.3 microg/g (R.S.D. 6.6%) in the liver.
