Overcoming barriers? The mixed results of social innovation accelerator programs for women entrepreneurs

Strategic Management Journal, Volume 47, Issue 6, Page 1576-1639, June 2026.
Abstract Research Summary Entrepreneurship accelerators are increasingly promoted as structural interventions to close gender gaps, yet studies have not established a differential impact of participation for women. This prior evidence—drawn from high‐tech, male‐dominated settings—may overlook how outcomes differ in more feminized domains such as social

A Hybrid Advanced Statistical Analysis and Decision Tree Algorithm Method for Power Transformer Fault Classification

Energies
Problems with power transformers reduce grid reliability and can lead to large financial losses. Traditional Dissolved Gas Analysis (DGA) methods, such as the Key Gas Method, Ratios, and Duval Triangle, often give unclear results when faults are complex ...
