Not All Games Play the Same: Specifying How Components of Video Games May be Associated With Creativity

The Journal of Creative Behavior, EarlyView.
ABSTRACT Understanding the impacts of digital media such as video games is critical for scholarship during the digital transformation. While the literature on the effects of video games continues to grow, there is little work on positive effects, including creativity, either as an outcome from or process within games.

Survive the economic downturn: Operating flexibility, productivity, and stock crash

Journal of Operations Management, EarlyView.
Abstract Operating flexibility supports a firm's resilience strategy during challenging times by enabling them to promptly cut down operating costs associated with unproductive resources. We employ a real options model to formalize this insight. Our empirically grounding analytics motivate a firm‐level proxy for downscale operating flexibility (FLEX ...

A Comparison of the Electrochemical Oxidative Dissolution of Pyrite and Chalcopyrite in Dilute Nitric Acid Solution

ChemistryOpen, EarlyView.
This research was primarily driven by the aim to extract residual encapsulated gold in sulfidic minerals, which would require the dissolution of the mineral. The electrochemical oxidation of pyrite and chalcopyrite in 0.5 M nitric acid was investigated here, using cyclic voltammetry and electrochemical impedance spectroscopy, to see if there are any ...
