Dynamic relationship between board gender diversity and renewable energy
(Chapter, 2021)This chapter investigates whether board gender diversity affects firms’ renewable energy use. Employing a sample of U.S. environmentally responsible firms, I find support for the hypothesis that board gender diversity ... -
Dynamic relationship between multiple START assessments and violent incidents over time: a prospective cohort study
(Journal article; Peer reviewed, 2014)Background: Dynamic risk factors need to be assessed repeatedly over time rather than at a single time point to examine the relationship with violence. This predictive validity study sought to examine the degree of ... -
Dynamic renormalization group of interfaces in scalar active matter
(Master thesis, 2022)Biologiske systemer er ofte bygget opp av partikler som er kapable til å transformere kjemisk energy som er lagret i systemet til arbeid eller felles bevegelse. Slike systemer kalles aktive systemer og kan eksemplifiseres ... -
