TL;DR: The greatest impediment to estimating the cost of productivity lost to illness is the lack of established and validated methods for monetization.
Abstract: The greatest impediment to estimating the cost of productivity lost to illness is the lack of established and validated methods for monetization. The issues raised in this review are intended to stimulate future research to validate and improve such methods.

TL;DR: In this paper, the dominant Lyapunov exponent (LE) is estimated for biological and economic systems that are subjected to random perturbations and observed over a limited amount of time.
Abstract: In the past twenty years there has been much interest in the physical and biological sciences in nonlinear dynamical systems that appear to have random, unpredictable behavior. One important parameter of a dynamic system is the dominant Lyapunov exponent (LE). When the behavior of the system is compared for two similar initial conditions, this exponent is related to the rate at which the subsequent trajectories diverge. A bounded system with a positive LE is one operational definition of chaotic behavior. Most methods for determining the LE have assumed thousands of observations generated from carefully controlled physical experiments. Less attention has been given to estimating the LE for biological and economic systems that are subjected to random perturbations and observed over a limited amount of time. Using nonparametric regression techniques (Neural Networks and Thin Plate Splines) it is possible to consistently estimate the LE. The properties of these methods have been studied using simulated data and are applied to a biological time series: marten fur returns for the Hudson Bay Company (1820-1900). Based on a nonparametric analysis there is little evidence for lowdimensional chaos in these data. Although these methods appear to work well for systems perturbed by small amounts of noise, finding chaos in a system with a significant stochastic component may be difficult.

TL;DR: Boarded-up housing may be related to mortality risk because of its potential adverse impact on social relationships and opportunities to engage in healthful behaviors.
Abstract: Objectives. We explored the relationship between boarded-up housing and rates of gonorrhea and premature mortality. Methods. In this ecological study of 107 US cities, we developed several models predicting rates of gonorrhea and premature death before age 65 from all causes and from specific causes. We controlled for race, poverty, education, population change, and health insurance coverage. Results. Boarded-up housing remained a predictor of gonorrhea rates, all-cause premature mortality, and premature mortality due to malignant neoplasms, diabetes, homicide, and suicide after control for sociodemographic factors. Conclusions. Boarded-up housing may be related to mortality risk because of its potential adverse impact on social relationships and opportunities to engage in healthful behaviors. Neighborhood physical conditions deserve further consideration as a potential global factor influencing health and well-being.

Journal ArticleDOI
TL;DR: Analysis of specific causes of death revealed that suicide, homicide/violence, and cardiovascular diseases were substantially elevated among sexual minorities in high-prejudice communities and highlighted the importance of examining structural forms of stigma and prejudice as social determinants of health and longevity among minority populations.
