Lessons from the Field: Striving for Transformative Change at the Stuart Foundation

The Stuart Foundation's Child Welfare Program provides a compelling example of what can be accomplished by a foundation that has clear goals, coherent, well-implemented strategies, and relevant performance indicators. This case study describes how Stuart implements its strategy to achieve its goal to improve life outcomes for foster youth

Compton scattering from the proton at NLO in the chiral expansion

We present calculations of differential cross sections for Compton scattering from the proton, using amplitudes calculated to fourth order in heavy baryon chiral perturbation theory. We compare with available data up to 200 MeV. We find that the agreement for angles below 90 degree is acceptable over the whole energy range, but that at more backward angles the agreement decreases above about 100 MeV, and fails completely above the photoproduction threshold.Comment: 13 pages RevTeX, 7 eps figures. Revised version correcting some errors, principally in the coding of 3rd order contributions; figures changed slightly and contribution from diagram 1h revised. Conclusions are largely unchanged, but the failure of the chiral expansion is visible at rather lower angles than appeared previously to be the cas

Outreach 2002: A collaborative schools project

In 2002, QUT Library conducted Outreach 2002, a collaborative trial project in which teaching staff from the Library and MacGregor SHS (MGSHS) developed models for the design, development and delivery of information literacy within the senior school curriculum

Calling Dick Tracy! Or, Cellphone Use, Progress, and a Racial Paradigm

The hero and phone-watch from Dick Tracy are evoked regularly in news and studies of cellphone use. This paper argues that the racial paradigm of White law enforcer and Dark law-breaker in the comic strip resonates in contemporary evocations and in discussions of cellphone use and crime. Representations of mobile communication and racialized criminality in Dick Tracy were inspired by the 1930s “war on crime” that intersected with wireless innovations and with lynching. This paper interprets that repeated evocation of the comic strip is a “perverse nostalgia” for an old-fashioned form of law and order premised on racialized violence and viewing

Spruce Budworm and Other Lepidopterous Prey of Eumenid Wasps (Hymenoptera: Eumenidae) in Spruce-Fir Forests of Maine

Three species of eumenid wasps, Ancistrocerus adiabatus, Ancistrocerus antilope, and Euodynerus Ieucomelas, accepted and provisioned trap-nesting blocks with lepidopterous larvae, A pyralid. Nephopteryx sp., was the most commonly provisioned prey. A. adiabarus and E. leucomelas preyed on late instars of the spruce budworm, Choristoneura fumiferana: however. budworms accounted for only 6% of the provisioned prey. Estimates of budworm population densities before and after wasp predation, and subsample-s of provisioned prey indicated no significant reductions i = 0.065%) in budworm populations attributable to trap-nesting wasps

Hidden in Plain Sight: Achieving More Just Results in Hostile Work Environment Sexual Harassment Cases by Re-Examining Supreme Court Precedent

Control of a hydraulic crane is considered. Due to the oscillatory character of the system smooth the operation of the crane is a demanding task. In order to improve the handling properties feedback control of the crane is studied. Based on linearized models feedback regulators of both LQG and PID type are designed. The feedback is based on position, pressure and acceleration measurements. Since the properties of the system change with load and operating point adaptive control is also introduced. The use of accelerometer signals for impact detection is also discussed. The proposed solutions are tested in both simulations and experiments on a real crane

Comment on "Nucleon spin-averaged forward virtual Compton tensor at large Q^2"

In recent work, Hill and Paz apply the operator product expansion to forward doubly virtual Compton scattering. The resulting large-$Q^2$ form of the amplitude $W_1(0,Q^2)$ is compatible with the one we obtain by extrapolation of low-$Q^2$ results from a chiral effective field theory, providing support for our approach. That paper also presents a result for the two-photon contribution to the Lamb shift in muonic hydrogen that has a much larger uncertainty than in previous work. We show that this an overestimate arising from the inclusion of the proton pole term in the subtracted dispersion relation for $W_1$.Comment: 3 pages; version accepted for publicatio
