Recent studies of the joint dynamics of ecological and evolutionary processes show that changes in genotype or phenotype distributions can affect population, community and ecosystem processes. Such eco-evolutionary dynamics are likely to occur in modern humans and may influence population dynamics. Here, we study contributions to population growth from detailed genealogical records of a contemp...

We use twins and gender of firstborns as instruments to estimate the effect of the number of children and the existence of a son on mother’ marital statuses.

We investigate the construction of more precise estimates of a collection of population means using information about a related variable in the context of repeated sample surveys. The method is illustrated using poll results concerning presidential approval rating (our related variable is political party identiŽ cation). We use poststratiŽ cation to construct these improved estimates, but becau...

Different proposals have been made in recent years to exploit Social Web tagging data to improve recommender systems. The tagging data was used for example to identify similar users or viewed as additional information about the recommendable items. In this work we propose to use tags as a means to express which features of an item users particularly like or dislike. Users would therefore not on...

Our previous analysis of 2015 Health Insurance Marketplace (HIM) data on plan availability and premiums in comparison to 2014 showed only modest premium increases in many rural areas and increased firm participation in most areas. To determine whether HIM enrollment also shows a positive trend, we analyzed county-level HIM enrollment data for 2015 by geographic categories, population density, p...
