Peer Networking and Community Change: Improving Foundation Practice
No full text· This article brings together the Annie E. Casey Foundation’s 15 years of experience with peer networking— examining through two research studies the process of peer networking and its impact, both with community-based and funder groups.
· Peer networking helps people with common interests to exchange information, disseminate good practices, and build a leadership structure for work they do together, such as a community change initiative.
· Casey’s research identified 10 good practices for effective peer networking, as well as 10 challenges that can affect its success; a four-level model was created to provide context for these findings.
· The research indicates that peer networking can have significant impact for communities and in meeting philanthropic goals, but it is costly and must be carefully structured if it is to be successful.
· Casey is working to synthesize its peer networking practices into a more strategic framework, and other foundations might use some of its lessons learned to enhance their own practices in this area

No full textProgress Code: completedHenk Brolsma and Roger Handsworth of the Australian Antarctic Division carried out GPS surveys at Casey, Casey skiway and Mitchell Peninsula in February 2009.<br/>At Casey they surveyed the quarry face, the wharf and the road from the quarry to the station and then to the wharf. They also collected the location of the tide gauges installed at the wharf.<br/>The Casey skiway was surveyed at the request of Andrew Pappas of Aeronautical Engineers Australia so the slope of the skiway could be determined.<br/>The survey at Mitchell Peninsula was done at the request of Casey Station Leader Graham Cook who considered the area surveyed to be a possible alternative site for a skiway.<br/><br/>The GPS data, shapefiles exported from the GPS data after postprocessing of the rover files against the base files and a document summarising the survey are available for download from a Related URL. <br/>The elevations of the point data in the shapefiles are above the WGS84 ellipsoid. <br/><br/>GIS data for Casey and the Windmill Islands were derived from the survey data.<br/>Casey: spot heights, quarry face, wharf, tide gauges.<br/>Windmill Islands: spot heights.<br/>The elevations of the spot height data are in metres above mean sea level.<br/>These data are part of the data available for download for Casey and the Windmill Islands - see Related URLs.<br/>The survey data were also used as a guide for revision of some of the road data for Casey, together with advice from the Station Leader Graham Cook. <br/>The GIS data are formatted according to the SCAR Feature Catalogue which includes data quality information.

Casey Station GIS Dataset update from various sources
No full textProgress Code: onGoingStatement: Usually mapped to a Universal Transverse Mercator projection, Zone 49.The Australian Antarctic Data Centre's Casey Station GIS data were originally mapped from Aerial photography (January 4 1994). Refer to the metadata record 'Casey Station GIS Dataset'. Since then various features have been added to these data as structures have been removed, moved or established. Some of these features have been surveyed. These surveys have metadata records from which the report describing the survey can be downloaded. <br/>However, the locations of other features have been obtained from a variety of sources. <br/>The data are included in the data available for download from the provided URLs. <br/>The data conforms to the SCAR Feature Catalogue which includes data quality information.

Tragidion densiventre Casey, new status
No full textTragidion densiventre Casey, new status (Figs 3 D–E, 7 E) Tragidion densiventre Casey, 1912: 322 Tragidion auripenne: Linsley, 1962: 115 Material examined: 57 specimens, including the type at USNM. Diagnosis. Linsley (1962) considered this species to be conspecific with T. auripenne. However, males of these two species are morphologically distinct. The integument of the head, legs, and scape of T. densiventre is red-brown, the elytra are tawny-tan in color with very deeply impressed elytral costae that curve slightly inward toward the suture, the basal black band of the elytra is broad and exceeds the scutellum by 2 × its length, the antennal tubercles are large and pronounced, and it is larger in size. Females of T. densivente are similar to females of T. auripenne. Tragidion densiventr e females can be distinguished by costae that curve inward toward the suture, and elytra that are red-orange (contrasted to yellow-orange in T. auripenne). Distribution (Fig. 7 E). The southern portions of the states of Arizona, New Mexico, and Texas, USA, and in northern Sonora and Chihuahua Mexico. Ecology. This species is predominantly found in xeric lowland desert habitats. Adults have been reared from Prosopis glandulosa and Acacia greggii. Adults aggregate on sap of Baccharis sarothroides, as well as on the flowers of the larval host plants. The biology of the larvae is unknown. Cope (1984) reported on the larval hosts of T. auripenne, however, this material now likely represents T. densiventre.Published as part of Swift, Ian & Ray, Ann M., 2008, A review of the genus Tragidion Audinet-Serville, 1834 (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini), pp. 1-25 in Zootaxa 1892 on pages 19-20, DOI: 10.5281/zenodo.27450
T–T Neutron Spectrum from Inertial Confinement Implosions
No full textA new technique that uses inertial confinement implosions for measuring low-energy nuclear reactions important to nuclear astrophysics is described. Simultaneous measurements of n–D and n–T elastic scattering at 14.1 MeV using deuterium–tritium gas-filled capsules provide a proof of principle for this technique. Measurements have been made of D(d,p)T (dd) and T(t,2n)[superscript 4]He (tt) reaction yields relative to the D(t,n)[superscript]He (dt) reaction yield for deuterium–tritium mixtures with fT/fD between 0.62 and 0.75 and for a wide range of ion temperatures to test our understanding of the implosion processes. Measurements of the shape of the neutron spectrum from the T(t,2n)[superscript 4]He reaction have been made for each of these target configurations.National Laser User’s Facility (Grant NA0000877)United States.

Investigation of the transition between hydrodynamic and kinetic regimes for DT exploding pushers at OMEGA and the NIF
No full textPrevious experiments were conducted to
study the transition from hydrodynamic-like to ion kinetic regimes
for D3He exploding pushers [1], demonstrating the importance of an
ion kinetic approach for formulating more robust predictions of implosion
characteristics. This presentation details a series of planned
experiments at the OMEGA Facility and the NIF using thin-glass
exploding pushers with DT fuel. D and T ions have the same charge,
unlike D and 3He, yet their masses are unaltered from the D and
3He case. This allows for the investigation of whether ion-thermal
decoupling and species separation are largely a result of charge or
mass. [2] The initial gas fill pressure will be varied in order to scan
the transition from strongly hydrodynamic to strongly kinetic implosions,
while leveraging the expansive diagnostic suite developed
at NIF and OMEGA.∗This work was supported in part by LLE, the U.S. DoE (NNSA,
