Germline Cancer Predisposition and De Novo Contributions in Pediatric Rhabdomyosarcoma: A Report From the Children's Oncology Group

International Journal of Cancer, EarlyView.
ABSTRACT Approximately 6%–8% of children and adolescents with rhabdomyosarcoma (RMS) have an underlying cancer predisposition disorder (CPD), which varies between embryonal and alveolar subtypes and other clinical characteristics. Identifying a CPD remains challenging, as traditional approaches rely on clinical features and family history. Additionally,

How Does Entrepreneurs' Grit Predict Effectual Decision‐Making?

Strategic Change, EarlyView.
ABSTRACT Entrepreneurs' grit is one of the most relevant predictors of new venture performance. We investigate whether the “stubbornness” of entrepreneurs' grit negatively relates to their effectual decision‐making abilities. Understanding the underlying mechanisms is relevant because the effectual decision‐making abilities of founders are crucial for ...
