Aeromagnetic investigations in East Greenland

open access: yesRapport Grønlands Geologiske Undersøgelse, 1975
During 1974, aeromagnetic profiling and mapping were carried out in two different parts of East Greenland (fig. 20). The most southerly area comprised the continental shelf between 63°30' and 66°N (Angmagssalik district), while the northern area covered the sedimentary basin of late Palaeozoic and Mesozoic rocks forming the land surface between 70° and

Lake sturgeon (Acipenser fulvescens) growth and longevity estimated from adult capture–mark–recapture data

open access: yesJournal of Fish Biology, EarlyView.
Abstract Effective fishery management policy depends on accurate life‐history data, particularly for harvested species. Longevity is a core life‐history trait that is directly related to annual survival and lifetime reproductive potential, but fish longevity is generally not well documented, particularly for long‐lived species.

Import competition and stock price crash risk

open access: yesJournal of Financial Research, EarlyView.
Abstract We investigate how globalization‐induced import competition affects stock price crash risk. Import competition increases price pressure and reduces profit margins, prompting managers to withhold negative information, resulting in higher crash risk. Based on a sample of US manufacturing firms from 1974 to 2019, we find that firms whose products
