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

Strategic Management Journal, EarlyView.Abstract Research Summary Though scholars employ abduction, there is no agreed‐upon structure to reporting their findings. Moreover, the traditional hypo‐deductive reasoning structure does not align with the epistemology of abduction. We propose an abductive testimonial structure, termed PEEBI, which consists of five sections in which the authors take ...

Small Methods, EarlyView.Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

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.

Advanced Hybrid Techniques for Cyberattack Detection and Defense in IoT Networks
SECURITY AND PRIVACY, Volume 8, Issue 2, March/April 2025.ABSTRACT The Internet of Things (IoT) represents a vast network of devices connected to the Internet, making it easier for users to connect to modern technology. However, the complexity of these networks and the large volume of data pose significant challenges in protecting them from persistent cyberattacks, such as distributed denial‐of‐service (DDoS)

Reverse engineering strut‐and‐tie models for assessing reinforced concrete structures
Structural Concrete, EarlyView.Abstract Strut‐and‐tie models enable the design of reinforced concrete structures with static or geometrical discontinuities, providing interpretability and control over the load path. These models are valuable for designing discontinuity regions of new structures and for validating nonlinear finite‐element analysis results. However, developing a strut‐

A Review on Jahn–Teller Distortions in Prussian Blue Analogs Molecular Magnets
The Chemical Record, EarlyView.This review highlights the central role of the Jahn–Teller effect in governing structural stability and electrochemical performance in Prussian blue analogs (PBAs). It establishes clear structure–property relationships and summarizes effective mitigation strategies, providing design guidelines for developing stable, high‐performance PBA‐based energy ...

The Value of Financial Advice and Portfolio Rebalancing for Retirement Savings
Accounting &Finance, EarlyView.ABSTRACT Utilising a sample of over 55,000 retirement portfolio rebalances, we examine (i) who seeks financial advice prior to rebalancing, and (ii) compare portfolio outcomes between advised and self‐directed rebalances. We find that wealthier, older, and female members are more likely to receive financial advice prior to rebalancing, and that advice ...

Identifiability conditions in cognitive diagnosis: Implications for Q‐matrix estimation algorithms
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract The Q‐matrix of a cognitively diagnostic assessment (CDA), documenting the item‐attribute associations, is a key component of any CDA. However, the true Q‐matrix underlying a CDA is never known and must be estimated—typically by content experts.

British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract The social relations model (SRM) is commonly used in psychological research to analyse interdependent data from round‐robin designs, where all members of a group rate each other. Based on the recently suggested social relations confirmatory factor analysis (SR‐CFA), we present general formulas for determining the reliability of composites of ...
