Wildlife Science: Gaining Reliable Knowledge
TL;DR: The thesis that wildlife research should use the H-D method to test research hypotheses, using the thresh- old-of-security hypothesis for winter mortality for illustration, and it is shown that persistent confusions about the definitions of concepts like carrying capacity, correlation and cause-and-effect stem from either inadequate or misused scientific methods.

A new microsimulation model for the evaluation of traffic safety performances
TL;DR: Assessment of the validity of traffic microsimulation for the analysis of road safety indicates that the methodology can be useful in the estimation of safety performance indicators and in evaluating traffic control measures.
A Simulation Study of the Estimation of Individual Specific Values of Time using an Adaptive Stated Preference Survey
TL;DR: In this paper, the authors used a simulation study to test the ability of ASP to produce unbiased estimates of the mean and standard deviation of the Value of Time (VOT) under certain conditions, namely that a 7-point rating scale is used to obtain responses, each respondent plays three games for each parameter to be estimated, the starting estimate of VOT used should be higher than the expected final mean value of VOTE, and a logit model sensitivity parameter of c=5 is used in the binary logits model used to convert probabilities of choice into utility differences.
