Local labor market frictions and platform‐based entrepreneurship

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Building on prior research about the heterogeneous impact of labor shocks on individuals' propensity to start businesses, we explore how local labor market frictions affect individuals' selection into platform‐based entrepreneurship.

A novel control strategy to suppress transient overvoltage balancing active power impact reduction caused by commutation failure

International Journal of Electrical Power & Energy Systems
The line-commutated high voltage direct current (LCC-HVDC) is easy to occur commutation failure (CF), during the CF and recovery period, lots of reactive power surplus can cause transient overvoltage (TOV) in the sending end system.

Visionary, engineer, and experimenter: Three forms of entrepreneurship in the quest for product–market fit

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.

Fixing the Leaky Pipeline: Affirmative Action in Local Elite Colleges and Subject Choice

Southern Economic Journal, EarlyView.
ABSTRACT Women are largely underrepresented in STEM careers associated with higher labor market returns. This gender gap is even more stark in a context where societal biases are prevalent and female role models are lacking. This paper investigates the impact of an affirmative action (AA) policy implemented in an elite educational institution in India ...

Monitoring the effects of ovariectomy on seasonal movement behavior in suburban female white‐tailed deer using internet of things‐enabled devices

Wildlife Biology, EarlyView.
Abundant deer populations often cause conflicts in suburban communities, yet traditional population reduction methods, such as controlled hunting, can be challenging to implement. Fertility control, specifically through ovariectomy, can limit reproduction and reduce populations in certain settings, but its effect on movement behavior remains poorly ...

Investigation of the Simplified Equivalent Circuit Model of the Post‐Arc Sheath Stage in DC Vacuum Circuit Breakers

High Voltage, EarlyView.
ABSTRACT This paper presents a simplified equivalent circuit model (ECM) for the post‐arc sheath stage in DC vacuum circuit breakers and outlines the method for calculating circuit parameters using the particle‐in‐cell Monte Carlo collision (PIC‐MCC) method. The post‐arc sheath is modelled as a parallel combination of a variable resistor and a variable
