Does Early Life Health Predict Schooling Within Twin Pairs? [PDF]

open access: yes
A large number of studies in labor economics estimate the returns to schooling using data on monozygotic twins, under the assumption that educational attainment is random within twin pairs. This exogeneity assumption has been commonly questioned, however,

Stem-Like Adaptive Aneuploidy and Cancer Quasispecies [PDF]

open access: yes, 2013
We analyze and reinterpret experimental evidence from the literature to argue for an ability of tumor cells to self-regulate their aneuploidy rate. We conjecture that this ability is mediated by a diversification factor that exploits molecular mechanisms

Genetic Susceptibility to Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Aim: The aim of this narrative review was to identify genes carrying risk alleles associated with an increased risk of periodontitis and to place them in a biological context. Methods: The literature was reviewed based on predefined criteria. Results: The identified genes largely fall into functions linking immune response with tissue repair. The genes

Sleep and Maladaptive Personality Traits: A Twin Study

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep is essential for human functioning, but little attention has been paid to the interplay between sleep and maladaptive personality traits. We examined genetic and environmental associations between sleep and four maladaptive domains (MDs)—Negative Affectivity, Detachment, Disinhibition, and Psychoticism—within the framework of the DSM‐5 ...

The Returns to Education: A Meta‐Study

open access: yesKyklos, EarlyView.
ABSTRACT There have been many studies estimating the causal effect of an additional year of education on earnings. The majority employ administrative changes in the minimum school‐leaving age as the mechanism allowing identification. Here, we survey 79 such estimates.
