Screening For Trauma In the Foster Care Community
Children within the foster care community experience health disparities on a variety of levels, from physical and mental health conditions, developmental delay, and impaired social interactions. Many of these conditions can stem from the experience of trauma or adverse childhood events that color each component of their lives. For healthcare providers to be successful in the assessment and treatment of this community, an understanding of traumatic events and the delivery of trauma-informed care is essential. The complex needs of this community are such that the provision of healthcare must be specialized, multidimensional, and organized. The purpose of this project is to assist in the development of a clinic that specializes in the delivery of primary care to the foster care community, with a focus on screening and assessment for the experience of trauma. Children were screened for child trauma as well as for resiliency behaviors, and a tool for chart review was used to examine current health status and services. With the assistance of stakeholders, meticulous follow up on screening results, referrals and recommendations made ensured that no opportunities were missed to provide the highest quality care for this underserved community
A Hubble Space Telescope Survey of X-ray Luminous Galaxy Clusters: Gravitationally Lensed Arcs and EROs
We are conducting a systematic lensing survey of X-ray luminous galaxy
clusters at z~0.2 using the Hubble Space Telescope and large ground-based
telescopes. We summarize initial results from our survey, including a
measurement of the inner slope of the mass profile of A383, and a search for
gravitationally lensed Extremely Red Objects.Comment: 4 pages, 2 figures. To appear in "A New Era in Cosmology" (ASP

Taxonomy of some Galeommatoidea (Mollusca, Bivalvia) associated with deep-sea echinoids: A reassessment of the bivalve genera Axinodon Verrill & Bush, 1898 and Kelliola Dall, 1899 with descriptions of new genera Syssitomya gen. nov. and Ptilomyax gen. nov.
The type species of Axinodon ellipticus Verrill & Bush, 1898 and Kellia symmetros Jeffreys, 1876 are re-described. It is concluded that the two species are not conspecific and that K. symmetros cannot be placed in the genus Axinodon. The family affinity of Axinodon is not resolved, although it is probable that this genus belongs to the Thyasiridae. Kellia symmetros is the type species of Kelliola and is placed in the Montacutidae. Kelliola symmetros is most probably associated with the echinoid Aeropsis rostrata and is not the species previously recorded from North Atlantic Pourtalesia echinoids under the name of Axinodon symmetros. This commensal associated with the North Atlantic Pourtalesia is here described as new and placed in the new genus as Syssitomya pourtalesiana gen. nov. sp. nov., Syssitomya gen. nov. differs from all other genera in the Montacutidae by having laminar gill filaments modified for harbouring symbiotic bacteria and it is thus assumed to be chemosymbiotic. A montacutid associated with the hadal Pourtalesia heptneri is described as Ptilomyax hadalis gen. nov. sp. nov
Hubble, chandra and keck constraints on massive galaxy clusters at z=0.2 and z=0.5
I present recent observations from two Hubble Space Telescope(HST)/ACS programs
that target the most X–ray luminous and thus (presumably) most massive galaxy clusters at
z=0.5 – the highest redshift at which complete, well–defined samples of such rare systems
are available. The first program (GO:9836, PI: R.S. Ellis) exploits a huge mosaic of 41 ACS
pointings spanning a 10 Mpc region centered on MS0451-03. This is the largest contiguous
space–based image of a cluster to date. I describe a preliminary weak–lensing analysis and a new
Keck/DEIMOS redshift catalog of 1000 galaxies in this field. The second program (GO:9722,
PI: H. Ebeling) studies the core regions of the twelve most luminous clusters at z≥0.5 from
the MAssive Cluster Survey (MACS; Ebeling et al. 2001). Multi–color ACS observations in
combination with recent Keck/LRIS spectroscopy of gravitational arcs constrain the distribution
of mass in the cluster cores, thus laying the foundation for detailed multi–diagnostic (lensing,
X–ray, near–infrared, SZE) investigation of this sample. For example, it is of particular interest
to explore how the structure and state of relaxation of massive clusters evolved between this
sample at z≥0.5 that measured by Smith et al. (2004, astro–ph/0403588) at z=0.2
LoCuSS: Weak-lensing mass calibration of galaxy clusters
We present weak-lensing mass measurements of 50 X-ray luminous galaxy
clusters at , based on uniform high quality observations with
Suprime-Cam mounted on the 8.2-m Subaru telescope. We pay close attention to
possible systematic biases, aiming to control them at the per cent
level. The dominant source of systematic bias in weak-lensing measurements of
the mass of individual galaxy clusters is contamination of background galaxy
catalogues by faint cluster and foreground galaxies. We extend our conservative
method for selecting background galaxies with colours redder than the
red sequence of cluster members to use a colour-cut that depends on
cluster-centric radius. This allows us to define background galaxy samples that
suffer per cent contamination, and comprise galaxies per square
arcminute. Thanks to the purity of our background galaxy catalogue, the largest
systematic that we identify in our analysis is a shape measurement bias of
per cent, that we measure using simulations that probe weak shears upto
. Our individual cluster mass and concentration measurements are in
excellent agreement with predictions of the mass-concentration relation.
Equally, our stacked shear profile is in excellent agreement with the Navarro
Frenk and White profile. Our new LoCuSS mass measurements are consistent with
the CCCP and CLASH surveys, and in tension with the Weighing the Giants at
significance. Overall, the consensus at that is
emerging from these complementary surveys represents important progress for
cluster mass calibration, and augurs well for cluster cosmology.Comment: 30 pages, 14 figures, 7 tables : accepted for the publication in

Bi-directional route learning in wood ants
Some ants and bees readily learn visually guided routes between their nests and feeding sites. They can learn the appearance of visual landmarks for the food-bound or homeward segment of the route when these landmarks are only present during that particular segment of their round trip. We show here that wood ants can also acquire landmark information for guiding their homeward path while running their food-bound path, and that this information may be picked up, when ants briefly reverse direction and retrace their steps for a short distance. These short periods of looking back tend to occur early in route acquisition and are more frequent on homeward than on food-bound segments
Carbon in soils
Carbon is the fourth most common element in the galaxy(by mass) but does not even rank in the twelve most abundant elements on Earth. By far the most abundant source of carbon on Earth is in the crust as inorganic rocks such as calcite and limestone in marine and sedimentary deposits. These rocks have taken many millions of years to form. Other major inorganic sources are in the oceans and atmosphere
Holonomy and Projective Equivalence in 4-Dimensional Lorentz Manifolds
A study is made of 4-dimensional Lorentz manifolds which are projectively
related, that is, whose Levi-Civita connections give rise to the same
(unparameterised) geodesics. A brief review of some relevant recent work is
provided and a list of new results connecting projective relatedness and the
holonomy type of the Lorentz manifold in question is given. This necessitates a
review of the possible holonomy groups for such manifolds which, in turn,
requires a certain convenient classification of the associated curvature
tensors. These reviews are provided.Comment: Comments: 23 pages, LaTeX; typos corrected, page 9 last line
