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.     

Abnormal Daily Temperature and Concern about Climate Change Across the United States

The relatively low level of concern about climate change among Americans has important implications for climate policy. While many studies have examined individual characteristics associated with climate change attitudes, fewer studies have considered the effects of environmental conditions on such attitudes. Here, we use two national samples of American adults to explore the impact of abnormal daily temperatures on levels of concern about climate change. We test the hypotheses that (1) abnormally warm temperatures, and (2) both abnormally warm and abnormally cool temperatures are associated with higher levels of concern. Using a generalized ordinal logit, we find that the quadratic form of deviation from mean temperature on the date of the survey is significantly associated with higher levels of concern, thus supporting the second hypothesis. We discuss several theoretical frameworks that may explain this result including availability bias, mental models, and implicit stimuli, and the implications for climate policy.     

Collective Action and Citizen Responses to Global Warming

This paper expands the relevance of the collective interest model of mass political action to explain collective-action behavior in the context of global warming and climate change. The analysis is an attempt to answer Ostrom’s call for a behavioral model of collective action that can be generalized beyond political protest to other collective-action problems. We elaborate, specify, and empirically test a collective interest model approach to citizen policy support, environmental political participation, and environmental behavior related to the issue of global warming. Key elements of the collective interest model—perceived risk, personal efficacy, and environmental values—are found to be directly, and positively, related to support of government policies and personal behaviors that affect global warming. We also discuss the links between the collective interest model and other important approaches to political behavior.

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.
