Avoidable causes of death and their effects on life expectancy. A socio-demographic interpretation. The case of the northern frontier, 1980-1990

"This study forms part of [a] research project on the health-disease-death process along the [Mexican] Northern Frontier--a by-product of the socio-economic structure of a specific social formation that determines disease and death--to support regional and sectorial design of policies and actions for the improvement of health conditions for its population.... An important finding is a 4.1 year increase of life expectancy due, among other causes, to a slight decrease in avoidable death causes, although these still produce about 50% of deaths."

Legislative Television as an Institutional Entry Barrier: The Impact of C-SPAN2 on Turnover in the U.S. Senate, 1946–1998

The present study examines the impactof televised U.S. Senate sessions (byC-SPAN2) on turnover rates in the U.S.Senate over the period 1946–1998. Using atheoretical model wherein politicalservices are viewed as search/experiencegoods, it is argued that there are manyparliamentary procedures available to U.S.Senators (e.g., filibustering, SpecialOrder Speeches, etc.) that serve them aslow-cost forms of persuasive advertising. These outlets provide opportunities forpolitical ``grandstanding'' on popular issueswhich challengers would have to spend largesums of money to combat and/or replicate. In this way C-SPAN (potentially) servesincumbent Senators as an entry barrier.
