TLDR
In this article, life cycle management (LCM) of civil infrastructures has been studied in order to achieve long service life and low probability of failure in infrastructure systems.Abstract:
Civil infrastructure systems have two essential characteristics: long service life and low probability of failure. Under these circumstances, life-cycle management (LCM) of civil infrastruc...read more

Regression and time series model selection in small samples
TL;DR: In this article, a bias correction to the Akaike information criterion, called AICC, is derived for regression and autoregressive time series models, which is of particular use when the sample size is small, or when the number of fitted parameters is a moderate to large fraction of the sample sample size.

Time Discounting and Time Preference: A Critical Review
TL;DR: In this paper, the authors discuss the discounted utility (DU) model, its historical development, underlying assumptions, and "anomalies" -the empirical regularities that are inconsistent with its theoretical predictions.
