Strategic Entrepreneurship Journal, EarlyView.Abstract Research summary Entrepreneurship unfolds under uncertainty, which complicates entrepreneurs' efforts to align idea, action, and environment to reach product–market fit. To illuminate how entrepreneurs perform such alignment, we complement the theory‐based view and its focus on cognitive uncertainty with a discussion of behavioral uncertainty.

Does innovation success need advocacy? Stakeholder involvement in firm innovation
Strategic Management Journal, EarlyView.Abstract Research Summary Prior research documents that firms often collaborate with advocacy groups to mitigate stakeholder contention. Integrating stakeholder theory into a performance model of collaborative innovation, we propose an overlooked explanation for such collaborations: to enhance the adoption of firms' innovations.

IEEE AccessAdvancing the firing angle implemented by the commutation failure prevention (CFPREV) is an effective method for commutation failure (CF), but the increase of reactive power consumption of local inverter would cause adverse influence on voltage at the ac

Bypassing SM strategy applied in interconnected LCC-HVDCs for commutation failure mitigation
, 2017 Recently, DC current reduction control for commutation failure mitigation is executed through point-to-point LCC-HVDC's rectifier. For an interconnected LCC-HVDC system through MMC-based DC-DC converter (MDC), MDC can be used to reduce the DC current ...

High Voltage, EarlyView.ABSTRACT To effectively suppress transient overvoltages in HVDC systems, the design and experimental validation of a multi‐module series controllable arrester are presented. The voltage‐limiting performance, series voltage equalisation capability, and robustness under fault conditions in high‐voltage scenarios require further research.

, 2021 Commutation failure at the inverter side of an MIDC (multi-infeed HVDC) is usually caused by AC system faults. Suppose the converter bus voltage cannot recover to the normal operation level in time: in that case, the commutation failure will then develop

The Mysterious Stranger and Modern Enchantment
The British Journal of Sociology, EarlyView.ABSTRACT Sociological accounts of modernity have long emphasized rationalization, alienation, and the attenuation of affective intensity. While these diagnoses capture crucial dynamics of modern social order, they leave underexplored a persistent and generative dimension of social life: enchantment.

A Quantile Model of Firm Investment
International Economic Review, EarlyView.ABSTRACT Are firms risk averse? We propose a dynamic model of firm investment under uncertainty that captures firms' risk attitudes through quantile preferences. The firm maximizes its present value, defined as current profits and investment plus the discounted value of the τ$\tau$‐quantile of its value next period.
