Contrasting population genetic structures of congeneric coastal flounders associated with different early life histories

open access: yesJournal of Fish Biology, EarlyView.

Social media, high‐frequency trading, and market making after‐hours – Evidence from presidential tweets

open access: yesJournal of Financial Research, EarlyView.

Short selling ETFs and market performance

open access: yesJournal of Financial Research, EarlyView.
Abstract We examine short selling activity in leveraged Exchange‐Traded Funds (ETFs) and its impact on underlying index performance. Using a novel measure of ETF short exposure, which includes long positions in inverse leveraged ETFs, we document that high short exposure is associated with positive performance in the subsequent period.

Identifying Out‐of‐the‐Box Virtual Reality Applications With Geriatric Applicability and Value

open access: yesJournal of the American Geriatrics Society, EarlyView.
ABSTRACT Background Virtual reality (VR) has the potential to improve the quality of life for older adults. Most studies use proprietary VR programs, specifically designed for one goal, which vastly limits the generalizability and use by the older adult population.
