    In response to the need for the Astro2020 Decadal Survey to explicitly engage early career astronomers, the National Academies of Sciences, Engineering, and Medicine hosted the Early Career Astronomer and Astrophysicist Focus Session (ECFS) on October 8-9, 2018 under the auspices of Committee of Astronomy and Astrophysics. The meeting was attended by fifty six pre-tenure faculty, research scientists, postdoctoral scholars, and senior graduate students, as well as eight former decadal survey committee members, who acted as facilitators. The event was designed to educate early career astronomers about the decadal survey process, to solicit their feedback on the role that early career astronomers should play in Astro2020, and to provide a forum for the discussion of a wide range of topics regarding the astrophysics career path. This white paper presents highlights and themes that emerged during two days of discussion. In Section 1, we discuss concerns that emerged regarding the coming decade and the astrophysics career path, as well as specific recommendations from participants regarding how to address them. We have organized these concerns and suggestions into five broad themes. These include (sequentially): (1) adequately training astronomers in the statistical and computational techniques necessary in an era of "big data", (2) responses to the growth of collaborations and telescopes, (3) concerns about the adequacy of graduate and postdoctoral training, (4) the need for improvements in equity and inclusion in astronomy, and (5) smoothing and facilitating transitions between early career stages. Section 2 is focused on ideas regarding the decadal survey itself, including: incorporating early career voices, ensuring diverse input from a variety of stakeholders, and successfully and broadly disseminating the results of the survey

    The Science Performance of JWST as Characterized in Commissioning

    This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performance of the spacecraft, telescope, science instruments, and ground system, with an emphasis on differences from pre-launch expectations. Commissioning has made clear that JWST is fully capable of achieving the discoveries for which it was built. Moreover, almost across the board, the science performance of JWST is better than expected; in most cases, JWST will go deeper faster than expected. The telescope and instrument suite have demonstrated the sensitivity, stability, image quality, and spectral range that are necessary to transform our understanding of the cosmos through observations spanning from near-earth asteroids to the most distant galaxies.Comment: 5th version as accepted to PASP; 31 pages, 18 figures; https://iopscience.iop.org/article/10.1088/1538-3873/acb29

    The James Webb Space Telescope Mission

    Full text link
    Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least 4m4m. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the 6.5m6.5m James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

    In Battering States: The Politics of Domestic Violence in Israel, anthropologist Madelaine Adelman utilizes an impressive array of ethnographic methods to examine how statecraft shapes domestic violence. Her thoughtful project is interdisciplinary in nature and analyzes when and how intimate partner violence intersects with cultural politics of the state. Her focus centers on Israel, where a number of distinctive factors make this a particularly compelling site for the type of study in which she engages: the existence of a “contentious multinational and multiethnic population,” “competing and overlapping sets of religious civil family law” (p. 2), pervasive state securitism and political violence, and widening economic disparity. As Adelman argues, while this exact combination of processes is unique to Israel, its component parts are not atypical of states with diverse populations in an era of globalization

    Classed Conceptions of Academic Self-Efficacy at an Elite University

    No full text
    Using the classic triadic model of class (lower, middle and upper), this paper explores how a students’ class-based cultural capital relates to their conceptualization and development of academic efficacy. Academic efficacy refers to the ability, not only of a student to think positively about their academic selves, but also to have and carry out plans that support their academic selves. Academic efficacy is positively associated with a myriad of student outcomes (Zajacova, Lynch and Espenshade 2005; Lent, Brown and Hackett 2000; Alfaro, Umaña-Taylor and BĂĄmaca 2006). The findings, based on in-depth interviews with 44 students at a highly selective private university, reveal that, compared to upper-class students, who predominantly reported high academic efficacy, the orientations among non-elite students were not as great. Findings suggest that policy makers should be paying attention not only to the experiences of lower-class students, but also to the difficulties unique to middle-class students at an elite university

    Battered Women Whose Cases Have Gone Through the System: The Role of Social Support

    No full text
    This paper explores the role of social support in the lives of battered women whose cases have gone through the criminal justice system. Using longitudinal data collected from almost 200 battered women whose cases went through the criminal justice system in three jurisdictions in the United States, explored are the types of support they received, variations in who receives support, differences between informal support and formal support, and the implications of social support in terms of violence and victims use of the criminal justice system
