Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

A rocket ozonesonde for geophysical research and satellite intercomparison [PDF]

The in-situ rocketsonde for ozone profile measurements developed and flown for geophysical research and satellite comparison is reviewed. The measurement principle involves the chemiluminescence caused by ambient ozone striking a detector and passive ...

Saving Bambi from the mower? Using a drone with thermal camera to evaluate a low‐tech scaring technique to reduce roe deer fawn mortality during grass harvest

Wildlife Biology, EarlyView.
Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

Miniaturized atmospheric ionization detector [PDF]

, 2018
A small scintillator-based detector for atmospheric ionization measurements has been developed, partly in response to a need for better ionization data in the weather-forming regions of the atmosphere and partly with the intention of producing a ...

Experimental assessment of large mammal population estimates from airborne thermal videography

Wildlife Biology, EarlyView.
Wildlife resource management requires reliable, fast, and affordable methods of surveying wildlife populations to develop and adaptively adjust policies. Thermal video from drones can yield high rates of detection over large areas with relative speed and safety.

A dog makes a difference: exploration of potential biases in moose‐hunting associated citizen science

Wildlife Biology, EarlyView.
The collection of citizen data is often employed to generate insights regarding species distribution, population sizes, and population structure; however, biases inherent in citizen science are seldom addressed. In this study, we examined the factors influencing hunters' observations of moose, Alces alces, during the moose hunting season in Finland. By
