Statistical Analysis of the Standardized Mortality Ratio and Life Expectancy
American journal of epidemiology, 1996Co-Authors: Dejian Lai, Robert J. Hardy, Shan P. TsaiAbstract:A new Theoretical Relation that does not require the constant age-specific mortality ratio assumption is established between the standardized mortality ratio (SMR) and the life expectancy. A set of regression equations is developed from the Theoretical Relation to derive estimates of the future expectation of life from estimates of the SMR. Curves are presented showing the changes in life expectancy that are associated with a given SMR for individuals aged 25, 45, and 65 years. These results will provide practical applications in estimating remaining life expectancy in epidemiologic studies in which the SMR is the summary statistic. An application is shown for studies in occupational health to develop and illustrate the method.

the standardized mortality ratio and life expectancy
American Journal of Epidemiology, 1992Co-Authors: Shan P. Tsai, Robert J. HardyAbstract:This paper describes a Theoretical Relation between the standardized mortality ratio (SMR) which is commonly used to ascertain the magnitude of risks experienced by a working population and life expectancy. The authors also attempt "to establish a statistical model for an easy method to convert the SMR of a study population to the corresponding life expectancy for that population." Data are from official sources for 1980 and concern the white population of the United States. (EXCERPT)

Theoretical Relation between water flow rate in a vertical fracture and rock temperature in the surrounding massif
Earth and Planetary Science Letters, 2001Co-Authors: Jean-christophe Maréchal, Pierre PerrochetAbstract:A steady-state analytical solution is given describing the temperature distribution in a homogeneous massif perturbed by cold water flow through a discrete vertical fracture. A Relation is derived to express the flow rate in the fracture as a function of the temperature measured in the surrounding rock. These mathematical results can be useful for tunnel drilling as it approaches a vertical cold water bearing structure that induces a thermal anomaly in the surrounding massif. During the tunnel drilling, by monitoring this anomaly along the tunnel axis one can quantify the flow rate in the discontinuity ahead before intersecting the fracture. The cases of the Simplon, Mont Blanc and Gotthard tunnels (Alps) are handled with this approach which shows very good agreement between observed temperatures and the Theoretical trend. The flow rates before drilling of the tunnel predicted with the Theoretical solution are similar in the Mont Blanc and Simplon cases, as well as the flow rates observed during the drilling. However, the absence of information on hydraulic gradients (before and during drilling) and on fracture specific storage prevents direct predictions of discharge rates in the tunnel.

trigger points and budget cuts explaining the effects of fiscal austerity
The American Economic Review, 1991Co-Authors: Giuseppe Bertola, Allan DrazenAbstract:We propose and solve an optimizing model which explains counterintuitive effects of fiscal policy in terms of expectations. If government spending follows an upward-trending stochastic process which the public believes may fall sharply when it reaches specific "target points," then optimizing consumption behavior and simple budget constraint arithmetic imply a nonlinear Relationship between private consumption and government spending. This Theoretical Relation is consistent with the experience of several countries.
