Micro‐transitions and work identity: The case of academic entrepreneurs
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary This paper examines how academic entrepreneurs—scientists who found research‐based startups while remaining in academia—construct and sustain their professional identities amid frequent transitions between academic and entrepreneurial roles.

Energies, 2012 With their highly robust nature and simple design, switched reluctance machines are finding their way into numerous modern day applications. However, they produce oscillatory torque that generates torque ripple and mechanical vibrations.

Deepening the real options debate: Real options as dynamic optimization
Strategic Management Journal, EarlyView.Abstract Research Summary Is real option theory useful for management research? This topic was hotly debated two decades ago. Real options were said to be inapplicable to management research and to lack conceptual distinctiveness. Whereas responses to the claim about the non‐distinctiveness of real options were disparate, the concern about the theory's

A Test of the Coase Conjecture Using Prices of Electronic Books
Southern Economic Journal, EarlyView.ABSTRACT The Coase Conjecture predicts that a durable‐goods monopolist without commitment will rapidly cut price toward marginal cost. We test this prediction in the electronic‐book market using release‐day prices. To proxy for marginal cost, we use competitive prices of public‐domain electronic books on the same platforms.

IET Electric Power Applications, 2020 This study presents comparative researches on performances of a double‐sided switched reluctance linear machine (DSRLM) under different winding connection modes. The static self/mutual inductances of a 6/4 yokeless DSRLM under two winding connection modes are calculated through the finite element method (FEM).

Managing Competency‐Based Resistance in Video‐Mediated L2 Peer Feedback Sessions
TESOL Quarterly, EarlyView.Abstract Though there is growing empirical evidence on managing advice resistance as an institutional work of higher status party with superior epistemic knowledge domain (e.g., trainer) across diverse settings (e.g., supervision meetings), there is still a lack of research on how second language (L2) learners handle peer resistance in real time once ...

Proctoring in a Second Language: Exploring Fairness and Justice in Remote English Language Testing
TESOL Quarterly, EarlyView.Abstract Remote proctoring is increasingly common in English language testing (Isbell & Kremmel, 2020), yet it often requires communication in the target language, unlike in‐person centers that may offer support in test‐takers' first language. Although prior studies have noted communication challenges in remote testing environments (Green & Lung, 2021;
