    Change Agents: The Goals and Impact of Women’s Foundations and Funds
    (2019-12-10) Gillespie, Elizabeth
    This research extends knowledge of women’s foundations and funds in the U.S. following the publication of a landscape scan of these organizations in May 2019. The landscape scan revealed that women’s foundations and funds use philanthropy to empower women, create positive change, and impact women and the broader community. They foster empowerment, change, and impact through grantmaking and by engaging in other activities, including advocacy and collaboration. The landscape scan also found that women’s foundations and funds often apply grantmaking philosophies, such as social change and gender lens philanthropy, and carry out their work through a variety of approaches. This study builds on the landscape scan to better understand how these organizations set goals, measure impact, and take action to advance the causes they care about.

    Change Agents: The Goals and Impact of Women’s Foundations and Funds - Executive Summary
    (2019-12-10) Gillespie, Elizabeth
    An earlier landscape scan of women’s foundations and funds in the U.S. revealed that they use philanthropy to empower women and create positive change that benefits women and the broader community. Change Agents builds on that landscape scan, extending knowledge of women’s foundations and funds to better understand how these organizations set goals, measure impact, and take action to advance women.

    How Women and Men Approach Impact Investing
    (2018-05-22) Osili, Una; Mesch, Debra; Ackerman, Jacqueline; Bergdoll, Jonathan; Preston, Linh; Pactor, Andrea
    The term impact investing evokes widespread interest, but few people have a deep understanding of the topic, and even fewer practice impact investing. What is impact investing? Who uses this investment strategy, and what are their objectives? Impact investing is relatively new and has developed rapidly over the last decade. The term itself was introduced in 2007 when the Rockefeller Foundation convened leaders in the fields of finance, philanthropy, and development, with the aim of building an industry of investing for impact.1 While a great deal has been written about the subject, most of this work comes from the world of finance and asks questions about financial return, comparing impact investing with investing purely for profit. The practice of impact investing is evolving exponentially, in contrast to research on this still-underexplored subject.

    Numerical Simulation of Impact Behavior of Ceramic Coatings Using Smoothed Particle Hydrodynamics Method
    (ASME, 2021-04) Zhang, Jian; Lu, Zhe; Sagar, Sugrim; Choi, Hyunhee; Jung, Yeon-Gil; Park, Heesung; Koo, Dan Daehyun; Zhang, Jing; Mechanical and Energy Engineering, School of Engineering and Technology
    In this work, the impact behavior of an alumina spherical particle on alumina coating is modeled using the smoothed particle hydrodynamics (SPH) method. The effects of impact angle (0 deg, 30 deg, and 60 deg) and velocity (100 m/s, 200 m/s, and 300 m/s) on the morphology changes of the impact pit and impacting particle, and their associated stress and energy are investigated. The results show that the combination of impact angle of 0 deg and velocity of 300 m/s produces the highest penetration depth and largest stress and deformation in the coating layer, while the combination of 100 m/s and 60 deg causes the minimum damage to the coating layer. This is because the penetration depth is determined by the vertical velocity component difference between the impacting particle and the coating layer, but irrelevant to the horizontal component. The total energy of the coating layer increases with the time, while the internal energy increases with the time after some peak values, which is due to energy transmission from the spherical particle to the coating layer and the stress shock waves. The energy transmission from impacting particle to coating layer increases with the increasing particle velocity and decreases with the increasing inclined angle. The simulated impact pit morphology is qualitatively similar to the experimental observation. This work demonstrates that the SPH method is useful to analyze the impact behavior of ceramic coatings.
