Asphyxial deaths as a result of aspiration of dental appliances: a report of three cases

Three cases of asphyxial deaths as a result of aspiration of dental appliances are presented. The possible association of this condition with resuscitative effort and patient debilitation is discussed. A recommendation to improve diagnosis and facilitate resuscitation is offered.     

Research expenditures,technology transfer activity,and university licensing revenue

In this paper we relate university licensing revenues to both university research expenditures and characteristics of the university and the university technology transfer office. We apply the Hausman–Taylor estimator for panel data with time-invariant explanatory variables and the Arellano–Bover dynamic panel model to unbalanced panels for the years 1991–2003 and balanced panels for the years 1995–2003. We find conflicting evidence regarding the short-term impacts of research expenditures on licensing revenues. On the other hand, both early initiation of technology transfer programs and staff size increase expected licensing revenues. Staff size and early entry appear to be substitutes, however. One-year lagged licensing revenue has strong predictive power for current licensing revenue. Further research is necessary to analyze changes in technology transfer office efficiency over time and the contribution of technology transfer to larger university missions.     

Book reviews

The article attempts to model structural adjustment patterns in a single, middle‐income oil exporter, Mexico. It explores the economy‐wide costs, in terms of economic growth, income inequality and poverty, of Mexico's economic stabilisation policies of the 1980s. On the basis of counterf actual simulation, it also explores the likely impacts of alternative adjustment strategies. This analysis utilises a modified Social Accounting Matrix (SAM) approach designed to overcome one of the major shortcomings of the conventional SAM: the assumption of unitary expenditure elasticities in household accounts. The base model is calibrated to track the overall and sectoral growth performance of the Mexican economy from 1980 to 1986 and becomes the foundation upon which our policy experiments are built. The article is part of an on‐going study of economy‐wide impacts of alternative structural adjustment policies in Mexico [Adelman and Taylor, 1990], and proceeds as follows: the SAM framework and estimated SAM are described in parts I and II; part III presents the base SAM model solution for 1980 to 1986; part IV presents the results of the policy experiments; and the conclusions are summarised in part V.
