Investigating European genetic history through computer simulations.

BACKGROUND/AIMS The genetic diversity of Europeans has been shaped by various evolutionary forces including their demographic history. Genetic data can thus be used to draw inferences on the population history of Europe using appropriate statistical methods such as computer simulation, which constitutes a powerful tool to study complex models. METHODS Here, we focus on spatially explicit simu...

Investigating Population History Using Temporal Genetic Differentiation

The rapid advance of sequencing technology, coupled with improvements in molecular methods for obtaining genetic data from ancient sources, holds the promise of producing a wealth of genomic data from time-separated individuals. However, the population-genetic properties of time-structured samples have not been extensively explored. Here, we consider the implications of temporal sampling for an...

Flexure on Dione: Investigating subsurface structure and thermal history

Using stereo generated topography of Dione, a moon of Saturn, we infer flexure across a prominent ridge on the leading hemisphere to estimate local elastic thickness and place constraints on Dione’s thermal evolution. Assuming topography is related to the flexing of a broken elastic plate, we estimate an effective elastic thickness of 3.5 ± 1 km. This local estimate is in good agreement with gl...

Investigating baseline neurocognitive performance between male and female athletes with a history of multiple concussion.

OBJECTIVE The purpose of this study was to examine, using a dose-response model, sex differences in computerised neurocognitive performance among athletes with a history of multiple concussions. DESIGN Retrospective with randomly selected concussion cases from four levels/numbers of previous concussion. SETTING Multicentre analysis of NCAA student-athletes.

Roots run deep: Investigating psychological mechanisms between history of family aggression and abusive supervision.

In this article, we examine the relationships between supervisor-level factors and abusive supervision. Drawing from social learning theory (Bandura, 1973), we argue that supervisors' history of family aggression indirectly impacts abusive supervision via both hostile cognitions and hostile affect, with angry rumination functioning as a first-stage moderator. Using multisource data, we tested t...
