Quantitative Leverage Through Qualitative Knowledge: Augmenting the Statistical Analysis of Complex Causes

Social scientific theories frequently posit that multiple causalmechanisms may produce the same outcome. Unfortunately, it isnot always possible to observe which mechanism was responsible.For example, IMF scholars conjecture that nations enter IMFagreements both out of economic need and for discretionary domesticpolitical reasons. Typically, though, all we observe is thefact of agreement, not its cause. Partial observability probitmodels (Poirier 1980, Journal of Econometrics 12:209–217; Braumoeller2003, Political Analysis 11:209–233) provide one methodfor the statistical analysis of such phenomena. Unfortunately,they are often plagued by identification and labeling difficulties.Sometimes, however, qualitative studies of particular casesenlighten us about causes when quantitative studies cannot.We propose exploiting this information to lend additional structureto the partial observability approach. Monte Carlo simulationreveals that by anchoring "discernible" causes for a handfulof cases about which we possess qualitative information, weobtain greater efficiency. More important, our method provesreliable at recovering unbiased parameter estimates when thepartial observability model fails. The paper concludes withan analysis of the determinants of IMF agreements.

The fiduciary duties of healthcare directors in the "zone of insolvency"

Directors of healthcare organizations normally owe fiduciary duties to their shareholders or, in the case of nonprofits, to the charitable mission of the organization. As an organization descends to bankruptcy, however, the board's duties may shift. At some point, the board may be imposed with different and often conflicting obligations to the corporate enterprise as a whole, with a primary criterion being the interests of creditors. In this article, the authors analyze the murky areas of the Zone and give guidance as to when the board's duty may shift-and as to how directors should proceed both in determining their duties and in working to fulfill them.     

Distance health services under the general agreement on trade in services

This Article discusses the state of distance health with respect to the General Agreement on Trade in Services (GATS). After examining the various aspects of telemedicine and its place in international trade, the author looks at the structure and functioning of GATS and how telemedicine is regulated under this agreement. The author argues that the potential for telemedicine under this agreement has yet to be fulfilled and suggests a number of ways to realize its potential. Ultimately, however, the author concludes that the single most important international trade objective for the United States healthcare industry should be to get its own house in order with respect to cross-border provision of health services. From an international trade perspective, the problem of non-uniform state licensure requirements within the United States makes it very difficult for the United States to negotiate market access commitments for distance health services with other countries. Therefore, it is not realistic to expect significant progress in the liberalization of distance health services until the United States has in place a reasonably uniform domestic system of licensure and regulation for telemedicine practitioners.     

Postmortem concentrations of citalopram

The postmortem concentrations of citalopram in blood, bile, liver, and vitreous humour were investigated in 14 cases using a specially developed high performance liquid chromatography assay. Concentrations from drug and non-drug related deaths were categorized to determine a postmortem therapeutic and toxic range. Therapeutic citalopram concentrations for blood, bile, liver, and vitreous humour ranged to 0.4 mg/L, 2.1 mg/l, 6.6 mg/kg, and 0.2 mg/L, respectively. In one potentially fatal response to citalopram, concentrations were 0.8 mg/L, 6.0 mg/L, 0.3 mg/L for blood, bile and vitreous humour, respectively.
