Priming Presidential Approval: The Conditionality of Issue Effects

Variations in the effectiveness of media priming are traditionally attributed to individual differences in political sophistication and news exposure. We contribute to this literature by considering the degree to which the content of an issue prime drives its use in presidential approval. Using a macro level approach, we combine public opinion data on presidential approval from 1981 to 2000 with content analyses of presidential news coverage to see how media attention affects the way issues are weighted in presidential approval. We find that the effectiveness of issue primes depends on issue content, such that familiar and understandable issues are more likely to be primed than more complex and difficult issues.

Establishing safe injection facilities in Canada: legal and ethical issues

In the face of an ongoing and escalating health crisis among injection drug users in Canada, calls are coming from many quarters to initiate safe injection facilities as a way to reduce overdoses, the spread of bloodborne diseases, and other health and community problems associated with injection drug use. This article summarizes a paper on safe injection facilities released in early 2002 by the Canadian HIV/AIDS Legal Network. The paper contributes to the policy discussion in Canada and sets out why and how the law should support the introduction of safe injection facilities.     

Eighteenth-Century Objections to Commerce: A Modern Economic Analysis

This article uses modern economic theory to analyze two majorarguments of the eighteenth-century agrarian opponents of thecommercial republic. The two arguments are the claim that commerceincreases the variety of people within the republic, and theclaim that the wealth generated by commerce retards the people'sability to govern themselves. This article replies that theproblems created by pluralism depend crucially on the scopeof the government's power. Pluralism is less problematic ina limited government than in a government with broad powers.The problems created by luxury are not unique to commerce, andarise in any situation in which self-government is successful.     

Improvisation and Mediation: Balancing Acts

Improvisation can be an important element of mediation practice, and there are several ways in which mediation practice correlates to improvisational performance. In this article, two mediation experts and two skilled jazz musicians explore the improvisational aspects of mediation. Two central themes emerge: (1) mediators often use improvisational techniques, and (2) by being improvisational, mediators can create environments that would encourage the parties themselves to be improvisational. We argue that practitioners can enhance their effectiveness as mediators by mastering improvisational skills.     

Structural determination of the principal byproduct of the lithium-ammonia reduction method of methamphetamine manufacture

One common method of illicit methamphetamine manufacture utilizes an alkali metal, typically lithium, and liquid ammonia to chemically reduce ephedrine or pseudoephedrine to form methamphetamine. This method is often referred to as the lithium-ammonia reduction method or the Birch reduction method. While the hydroxyl group of ephedrine is more reactive than the aromatic ring, excess alkali metal and the presence of a proton source allow the formation of a cyclohexadiene byproduct not found in samples of methamphetamine produced from other manufacturing methods. A sample enriched in this byproduct was generated and characterized using nuclear magnetic resonance (NMR) spectroscopy, gas chromatography-mass spectrometry (GC-MS), infrared (IR) spectrophotometry, and ultraviolet (UV) spectrophotometry. The chemical structure of this byproduct was determined to be 1-(1',4'-cyclohexadienyl)-2-methylaminopropane (CMP).     

The Role of Victim-Related Factors in Victim Restitution: A Multi-Method Analysis of Restitution in Pennsylvania

Mandatory statutes do not always produce change, but a 1995 Pennsylvania statutory change making restitution mandatory dramatically increased the proportion of cases in which restitution was imposed. There are three possible reasons for this generally successful implementation: (a) judges agreed with the victim-centered goals of the statute, (b) there were mechanisms in place to implement the goals of assisting victims, and (c) there was a context supportive of victims that made it easier to follow the law. Two studies investigated these possible explanations. First, a statewide survey of trial court judges suggested that they agreed with the statute's goals of compensating victims. Second, hierarchical logistic models of 55,119 statewide restitution-eligible decisions indicated that a victim-related contextual factor, the nature and location of the victim/witness assistance office, was significantly related to the imposition of restitution, although a more general contextual factor relating to funding for victim programs had only small effects.
