Simultaneous analysis of d-3-methoxy-17-methylmorphinan and l-3-methoxy-17-methylmorphinan by high pressure liquid chromatography equipped with PDA

d-3-Methoxy-17-methylmorphinan (Dextromethorphan, DXM), which is a structural analog of morphine and codeine, has been widely used as a non-narcotic antitussive agent. It is a safe drug in therapeutic dose and does not produce analgesic effects, while its enantiomer, l-3-methoxy-17-methylmorphinan called levomethorphan (LXM) is a potent narcotic analgesic. DXM has been widely abused in Korea due to its hallucinogenic effect in large doses; therefore, the health authorities have regulated its use as a psychotropic agent since 2003. As its abuse has been serious, a possibility that DXM would be smuggled into Korea has also increased. Moreover, it has been suspected that there was the possibility of the adulteration or substitution of DXM with LXM due to their chemical similarities. Therefore, it was necessary for us to establish the enantiomeric separation of DXM and LXM. In this study, a liquid chromatographic method using a chiral column capable of separating stereoisomers of DXM as well as analyzing the major metabolites of DXM, 3-methoxymorphinan, 3-hydroxymorphinan, and 17-hydroxymethylmorphinan was developed. The validation of a method was studied through repeatability of retention times. Using this method, 32 confiscated DXM samples were analyzed to identify the enantiomers of DXM. As a result, DXM was detected in all samples and there was no evidence of the adulteration or substitution of DXM with LXM. Nevertheless, the stereochemical analysis of DXM and LXM is important not only to identify starting materials for illegal drug manufacture but also to understand the trends of abused drugs.     

Emotions and Attributions of Legal Responsibility and Blame: A Research Review

Research on the effects of emotions and moods on judgments of legal responsibility and blame is reviewed. Emotions and moods may influence decision makers in 3 ways: by affecting their information processing strategies, by inclining their judgments in the direction of the valence of the emotion or mood, and/or by providing informational cues to the proper decision. A model is proposed that incorporates these effects and further distinguishes among various affective influences in terms of whether the affect is provoked by a source integral or incidental to the judgment task, and whether it affects judgment directly (e.g., by providing an informational cue to judgment) or indirectly (e.g., by affecting construal of judgment target features, which in turn affects the judgment). Legal decision makers' abilities to correct for any affective influences they perceive to be undesirable and normative implications for legal theory and practice are briefly discussed.     

Dialogue in American Political Campaigns? An Examination of Issue Convergence in Candidate Television Advertising

The theory of issue ownership holds that competing candidates should avoid discussing many of the same issues during a campaign. In contrast, theories of democracy suggest that competitive elections are the mechanism by which the public can hold politicians accountable. To determine the extent to which each theory depicts current campaigns, we develop a new measure of "issue convergence" and test whether or not issue convergence increases as the competitiveness of the race increases. Using new data based upon television advertising aired in U.S. Senate campaigns from 1998 through 2002, we find that issue engagement or dialogue occurs more frequently than indicated by previous research. We also find that issue engagement increases with the competitiveness of the race but that issue engagement decreases as the gap in financial resources between candidates increases.
