Advancing Information Design for Architectural Image Interfaces
A Level II Digital Humanities Start-Up grant of $49,673 is requested for the design and implementation of an innovative and highly sophisticated user interface for the Brumfield Russian Architecture Photographic Collection of some 30,000 images, which has been digitized and cataloged by the University of Washington Libraries-- an enormously labor-intensive process. This work was supported by an NEH grant in 2006-2009, an earlier pilot grant from the Gladys Kriebel Delmas Foundation, and subsequent smaller awards from the Allen and Smith Foundations. This project will realize in a fully functioning interface both the possibilities inherent in the already innovative metadata structure devised for the collection under the previous grants, and the potential of the most recent techniques and strategies for managing and presenting large and complex data sets on the internet
Dear Officer Bogash: Policing Black Bodies on College Campuses
Students\u27 Critical Reflections on Racial (in)justic
Lemons Into Lemonade: Black Undergraduate Women\u27s Embodiment of Strength and Resilience at a PWI
This dissertation is a qualitative research project for Black undergraduate women and about Black undergraduate women. The aim of this dissertation is to lift, center, and share the lived experiences of Black undergraduate women as they reflect on the messages and memories of coming into their Blackness, their transition to and experiences while attending a PWI, and the ways in which they continue to make meaning of space. Informed by Black Feminist Theory and Critical Race Theory, the framework and methods used in this project prioritize the care of the participants and allow them to be co-creators of their own experiences. I argue throughout that there is an opportunity in more traditional higher education literature to approach the work from an interdisciplinary lens, bringing in Black Feminist Theory as a critical body of scholarship that tells us something else about Black undergraduate women from an intersectional lens. Without approaching scholarship about Black undergraduate women from an intersectional framework, we miss the voices and stories that my participants shared. At a moment when the need to heal from racial trauma was heightened, this study demonstrated the power of SOLHOT as a method and the ways in which intentional design, sustained dialogue, and an understanding of Black women allows for a beautifully unique space in higher education at PWIs. Through this dissertation, I found that Black undergraduate women (1) receive ongoing messages prior to attending college that inform them and their coming into Blackness experience, (2) are resilient despite the barriers, obstacles, and violence they encounter at their PWI, and (3) seek space that allows them to show up as authentically as possible and affirms, honors, and acknowledges them as enough. This dissertation aims to disrupt the majoritarian narratives about us, educated Black women, and invites the reader to see, hear, and feel us as whole people with deeply powerful stories and resiliency that is unmatched. As Black women, we always make lemonade when given lemons because we are innately strong, empowered, and fierce
The ACS Virgo Cluster Survey XV. The Formation Efficiencies of Globular Clusters in Early-Type Galaxies: The Effects of Mass and Environment
The fraction of stellar mass contained in globular clusters (GCs), also
measured by number as the specific frequency, is a fundamental quantity that
reflects both a galaxy's early star formation and its entire merging history.
We present specific frequencies, luminosities, and mass fractions for the
globular cluster systems of 100 early-type galaxies in the ACS Virgo Cluster
Survey, the largest homogeneous catalog of its kind. We find that 1) GC mass
fractions can be high in both giants and dwarfs, but are universally low in
galaxies with intermediate luminosities. 2) The behavior of specific frequency
across galaxy mass is dominated by the blue GCs. 3) The GC fractions of
low-mass galaxies exhibit a dependence on environment. Nearly all dwarf
galaxies with high GC fractions are within 1 Mpc of the cD galaxy M87,
presenting the first strong evidence that GC formation in dwarfs is biased
toward dense environments. 4) GC formation in central dwarfs is biased because
their stars form earliest and most intensely. Comparisons to the Millennium
Simulation show that central dwarfs have older stellar populations and form
more stars at higher star formation rates (SFRs) and SFR surface densities. The
SFR surface density in simulated dwarfs peaks before the total SFR, naturally
producing GC populations that are older and more metal-poor than the field
stars. 5) Dwarfs within ~40 kpc of the giant ellipticals M87 and M49 are red
and have few or no GCs, suggesting that they have been tidally stripped and
have contributed their GCs to the halos of their giant neighbors. The central
dwarfs with high GC mass fractions are thus likely to be the survivors most
similar to the protogalaxies that assembled the rich M87 globular cluster
system.(Abridged)Comment: 27 pages, 21 figures, 7 tables. Accepted for publication in the

The ACS Fornax Cluster Survey. II. The Central Brightness Profiles of Early-Type Galaxies: A Characteristic Radius on Nuclear Scales and the Transition from Central Luminosity Deficit to Excess
We analyse HST surface brightness profiles for 143 early-type galaxies in the
Virgo and Fornax Clusters. Sersic models provide accurate descriptions of the
global profiles with a notable exception: the observed profiles deviate
systematically inside a characteristic "break" radius of R_b ~ 0.02R_e where
R_e is the effective radius of the galaxy. The sense of the deviation is such
that bright galaxies (M_B < -20) typically show central light deficits with
respect to the inward extrapolation of the Sersic model, while the great
majority of low- and intermediate-luminosity galaxies (-19.5 < M_B < -15) show
central light excesses; galaxies occupying a narrow range of intermediate
luminosities (-20 < M_B < -19.5) are usually well fitted by Sersic models over
all radii. The slopes of the central surface brightness profiles, when measured
at fixed fractions of R_e, vary smoothly as a function of galaxy luminosity in
a manner that depends sensitively on the choice of measurement radius. We show
that a recent claim of strong bimodality in slope is likely an artifact of the
galaxy selection function used in that study. To provide a more robust
characterization of the inner regions of galaxies, we introduce a parameter
that describes the central luminosity deficit or excess relative to the inward
extrapolation of the outer Sersic model. We find that this parameter varies
smoothly over the range of ~ 720 in blue luminosity spanned by the Virgo and
Fornax sample galaxies, with no evidence for a dichotomy. We argue that the
central light excesses (nuclei) in M_B > -19 galaxies may be the analogs of the
dense central cores that are predicted by some numerical simulations to form
via gas inflows. (ABRIDGED)Comment: To appear in the Astrophysical Journal, December 2007. Full

Preceptor Facilitated Debriefing Improves Athletic Training Student’s Clinical Performance and Work Efficacy
Debriefing is an essential part of healthcare training that utilizes a planned conversation to allow clinicians to analyze their actions, thought processes, and emotions with the goal of improving patient care and outcomes. Debriefing requires two-way communications between the athletic training student and facilitating preceptor. The process is more than providing feedback on clinical performance, but a communication process that fosters reflective insight into of behaviors and decisions. Debriefing after patient care encounters has been shown to increase critical thinking, confidence, clinical skill and clinical reasoning. With this enhancement in cognition and behavior, debriefing allows the student to strengthen their own capabilities and efficacy, better preparing themselves for real time clinical practice. Facilitating effective debriefing is challenging for seasoned educators, as well as practitioners untrained to facilitate effective debriefing
Intergalactic Globular Clusters
We confirm and extend our previous detection of a population of intergalactic
globular clusters in Abell 1185, and report the first discovery of an
intergalactic globular cluster in the nearby Virgo cluster of galaxies. The
numbers, colors and luminosities of these objects can place constraints on
their origin, which in turn may yield new insights to the evolution of galaxies
in dense environments.Comment: 2 pages, no figures. Talk presented at JD6, IAU General Assembly XXV,
