Summer 2020 Re Visiting a Past Event
REINVENTING AMERICAN DEMOCRACY FOR THE 21ST CENTURY THE INTERSECTION OF DEMOCRACY & RELIGION A Nation in Crisis SUMMER 2020 RE VISITING A PAST EVENT Policy Perspectives on Police Use of Lethal Force As America reckons with its relationship to police violence, we are reminded that progress can be slow. It has been more than five years since the deaths of Michael Brown and Eric Garner. On February 4, 2015, the Academy convened a discussion at the University of California, Berkeley, led by Andrea Roth (Assistant Professor of Law, University of California, Berkeley School of Law) and Franklin Zimring (William G. Simon Professor of Law, University of California, Berkeley School of Law) about the hundreds of people who are killed each year by police, the racial disparity among the victims, and the incomplete data that make analyzing the problem so difficult. The conversation also covered the effectiveness of various avenues for police reform. To read the full transcript of this event (published in the Spring 2015 issue of the Bulletin) and hundreds of other Stated Meetings from the last twenty years, please visit amacad.org/bulletin.

An Interview with Ewine Van Dishoeck
Issue 52 j October 2018 . Dear Colleagues, Welcome to the 5th anniversary edition of AstroPAH! What better way to cele- brate this festive occasion with you than with a show of lasers as featured on our cover. This year’s Nobel Prize in physics went to Arthur Ashkin, Gerard´ Mourou and Donna Strickland for their ground-breaking work in creating tools made of light. As the cover reveals, this has been of utmost importance to multiple fields amongst which astronomy and chemistry. Noteworthy is that Donna Strickland is the 3rd woman ever to win a Nobel Prize in physics (and the 1st in over 50 years). We would further like to celebrate our anniversary with a tribute to our Kavli-price winner Ewine van Dishoeck, who was awarded this ”Nobel-price for astronomy” for her ”combined contributions to observational, theoretical, and laboratory astrochemistry, elucidating the life cycle of interstellar clouds and the formation of stars and planets” Enjoy our interview with her in the In Focus. Of course our newsletter itself is also ’In Focus’ with some nice numbers from your feedback, showing our impact in the community. Thanks to all of you who responded to our survey! We will take your feedback into account to improve our newsletter and continue to keep you updated on the rich field of PAH-related research. We also thank everyone who has sent their paper abstracts to us, in this issue and all previous ones. Once again, our abstract section is full of interesting papers on the- oretical, experimental, and observational studies of astronomical PAHs and so much more. -

Biography Authored Books Edited Books Journal Articles
Kirstie Fryirs Faculty of Science and Engineering Email: [email protected] Phone: +61 2 9850 8367 Biography Kirstie's work focuses on fluvial geomorphology and river management. Her research focusses on how rivers work, how they have evolved, how they have been impacted by anthropogenic disturbance, how catchment sediment budgets and (dis)connectivity work, and how to best use geomorphology in river management practice. She is probably best known as the co-developer of the River Styles Framework and portfolio of professional development short courses (see www.riverstyles.com). The River Styles Framework is a geomorphic approach for the analysis of rivers that includes assessment of river type and behaviour, physical condition and recovery potential. These analyses are used to develop prioritisation and decision support systems in river management practice. Uptake of the River Styles Framework has now occurred in many places on six continents. Kirstie has strong domestic and international collaborations in both academia and industry. She has worked for many years on various river science and management projects as part of multi-disciplinary, collaborative teams that include ecologists, hydrologists, social scientists, practitioners and citizens. Kirstie has also been lucky enough to work in Antarctica for two summer seasons, undertaking research on heavy metal contamination at Casey and Wilkes stations. Kirstie has co-written and co-edited three books titled "Geomorphology and River Management" (Blackwell, 2005), "River Futures" (Island Press, 2008) and "Geomorphic Analysis of River Systems: An Approach to Reading the Landscape" (Wiley, 2013). She holds several research, teaching and postgraduate supervision awards including the international Gordon Warwick medal for excellence in research. -

Sternberg TRIENNIAL REPORT 2009-2012 1. Introduction The study of molecules in space, known as astrochemistry or molecular astrophysics, is a rapidly growing field. Molecules exist in a wide range of environments in both gaseous and solid form, from our own solar system to the distant early universe. To astronomers, molecules are indispensable and unique probes of the physical conditions and dynamics of regions in which they are detected, especially the interstellar medium. In particular, the many stages of both low-mass and high-mass star formation are better understood today thanks to the analysis of molecular observations. Molecules can also yield a global picture of the past and present of sources. Moreover, molecules affect their environment by contributing to the heating and cooling processes that occur. Molecular observations are currently being used to study the interstellar gas and dust in diffuse interstellar clouds, dense molecular clouds, protostellar objects, maser and star-forming regions, envelopes of evolved stars, protoplanetary disks, (exo-)planetary atmospheres and comets. In addition to our own Milky Way Galaxy, molecules and solid- state features are routinely detected in interstellar regions of external galaxies ranging from the nearby Magellanic Clouds to distant starbust galaxies at redshifts of more than 6. -
