Ad Watch 3.0: Developing Audiovisual and Narrative Techniques for Engaging the Audiovisual Content of Political Advertising

Analysis of the evolution and practice of ad watch journalism during the 2000, 2004, 2008, and 2012 presidential campaigns suggests a robust level of ad watch activity, fostered in part by advances in communications technology and the proliferation of actors with means and motive. The efforts of ad watch practitioners to police egregious distortions and deceptions continue to provide an important baseline in the broader discourse surrounding the veracity of campaign claims. Efforts to place the transgressions of campaign spots in a proper context, however, have been met with at best, mixed success. Among the principal challenges to building a better ad watch for the 21st century are engaging the way audiovisual elements of ads advance their case by evoking readily accessible narrative frames grounded in popular culture; developing the multiple metrics by which candidates’ fidelity to the truth over time can be effectively evaluated; and addressing arguments about the character of candidates, arguments often ostensibly framed in overtly policy terms

A high resolution millimetre and submillimetre study of W3

The continuum bolometer receiver on the James Clerk Maxwell telescope has been used to map the dense core of the star formation region W3 with a spatial resolution of 15-20 arcsec. At 350 and 800 μm, the region appears as two principal peaks around the known IR sources IRS4 and IRS5, while at 1100 μm, a further peak is noted which is interpreted as being due to free-free emission around IRS2. Taking into account the free-free contribution to the intensity, the continuum dust emission from the region is found to be consistent with optically thin emission at all of the three wavelengths considered. Values for the dust optical depth, hydrogen column density, mass, and central density have been obtained for each of the main peaks

Submillimetre CO observations of the Cepheus A outflow

The authors have carried out spectral mapping of the Cep A region in the J = 3-2 transition of CO. The high velocity wings symptomatic of outflowing gas are evident over a region ~6×6 arc min in extent (~1.3×1.3 pc). There appear to be 2 outflows, as found also for HCO+ by Loren et al. (1985). The CO J = 3-2 red wing intensity is enhanced relative both to lower transition CO data and to HCO+ J = 1-0, particularly to the south and east of Cep A, a result which suggests the presence of hot, optically thin gas in the flow. No such significant enhancement is seen, however, in the blue wing. The data are discussed in terms of a 2 component outflow in which the HCO+ emission originates mainly from dense clumps in the flow while a less dense (but >4×104cm-3) interclump medium is responsible for most of the 12CO emission

Submillimeter wavelength molecular spectroscopy of the Orion molecular cloud

A submillimeter wavelength spectroscopic study of the Orion molecular cloud has been made in the J = 4-3 HCN, H13CN, HCO+, H13CO+, and J = 7-6 CS molecular transitions. Densities of up to a few times 106 cm-3 are found coupled with high inferred brightness temperatures, indicating kinetic temperatures of 120 K. Evidence for lower densities in the surrounding ambient molecular cloud is presented along with maps of HCN and HCO+ emission. The maps indicate different spatial distributions in the two lines. The abundances of HCN and HCO+ in the plateau source are found to be enhanced relative to those in the surrounding molecular cloud, and there is a suggestion that a number of small-angular-diameter clumps may be present. The present observations do not confirm the previously reported detection of CO+ in the interstellar medium

Evaluation of an Emergency Department Educational Campaign for Recognition of Suicidal Patients

Introduction: To evaluate the impact of a simple emergency department (ED)–based educational intervention designed to assist ED providers in detecting occult suicidal behavior in patients who present with complaints that are not related to behavioral health.Methods: Staff from 5 ED sites participated in the study. Four ED staff members were exposed to a poster and clinical guide for the recognition and management of suicidal patients. Staff members in 1 ED were not exposed to training material and served as a comparator group.Results: At baseline, only 36% of providers reported that they had sufficient training in how to assess level of suicide risk in patients. Greater than two thirds of providers agreed that additional training would be helpful in assessing the level of patient suicide risk. More than half of respondents who were exposed to the intervention (51.6%) endorsed increased knowledge of suicide risk during the study period, while 41% indicated that the intervention resulted in improved skills in managing suicidal patients.Conclusion: This brief, free intervention appeared to have a beneficial impact on providers’ perceptions of how well suicidality was recognized and managed in the ED.

Abundance, behavior, and movement patterns of western gray whales in relation to a 3-D seismic survey, Northeast Sakhalin Island, Russia

A geophysical seismic survey was conducted in the summer of 2001 off the northeastern coast of Sakhalin Island, Russia. The area of seismic exploration was immediately adjacent to the Piltun feeding grounds of the endangered western gray whale (Eschrichtius robustus). This study investigates relative abundance, behavior, and movement patterns of gray whales in relation to occurrence and proximity to the seismic survey by employing scan sampling, focal follow, and theodolite tracking methodologies. These data were analyzed in relation to temporal, environmental, and seismic related variables to evaluate potential disturbance reactions of gray whales to the seismic survey. The relative numbers of whales and pods recorded from five shore-based stations were not significantly different during periods when seismic surveys were occurring compared to periods when no seismic surveys were occurring and to the post-seismic period. Univariate analyses indicated no significant statistical correlation between seismic survey variables and any of the eleven movement and behavior variables. Multiple regression analyses indicated that, after accounting for temporal and environmental variables, 6 of 11 movement and behavior variables (linearity, acceleration, mean direction, blows per surfacing, and surface-dive blow rate) were not significantly associated with seismic survey variables, and 5 of 11 variables (leg speed, reorientation rate, distance-from-shore, blow interval, and dive time) were significantly associated with seismic survey variables. In summary, after accounting for environmental variables, no correlation was found between seismic survey variables and the linearity of whale movements, changes in whale swimming speed between theodolite fixes, mean direction of whale movement, mean number of whale exhalations per minute at the surface, mean time at the surface, and mean number of exhalations per minute during a whales surface-to-dive cycle. In contrast, at higher received sound energy exposure levels, whales traveled faster, changed directions of movement less, were recorded further from shore, and stayed under water longer between respirations

Observation of direct-photon collective flow in sqrt(s_NN)=200 GeV Au+Au collisions

The second Fourier component v_2 of the azimuthal anisotropy with respect to the reaction plane was measured for direct photons at midrapidity and transverse momentum (p_T) of 1--13 GeV/c in Au+Au collisions at sqr(s_NN)=200 GeV. Previous measurements of this quantity for hadrons with p_T < 6 GeV/c indicate that the medium behaves like a nearly perfect fluid, while for p_T > 6 GeV/c a reduced anisotropy is interpreted in terms of a path-length dependence for parton energy loss. In this measurement with the PHENIX detector at the Relativistic Heavy Ion Collider we find that for p_T > 4 GeV/c the anisotropy for direct photons is consistent with zero, as expected if the dominant source of direct photons is initial hard scattering. However, in the p_T < 4 GeV/c region dominated by thermal photons, we find a substantial direct photon v_2 comparable to that of hadrons, whereas model calculations for thermal photons in this kinematic region significantly underpredict the observed v_2.Comment: 384 authors, 6 pages, 3 figures, and 1 table.

Azimuthal anisotropy of pi^0 and eta mesons in Au+Au collisions at sqrt(s_NN)=200 GeV

The azimuthal anisotropy coefficients v_2 and v_4 of pi^0 and eta mesons are measured in Au+Au collisions at sqrt(s_NN)=200 GeV, as a function of transverse momentum p_T (1-14 GeV/c) and centrality. The extracted v_2 coefficients are found to be consistent between the two meson species over the measured p_T range. The ratio of v_4/v_2^2 for pi^0 mesons is found to be independent of p_T for 1-9 GeV/c, implying a lack of sensitivity of the ratio to the change of underlying physics with p_T. Furthermore, the ratio of v_4/v_2^2 is systematically larger in central collisions, which may reflect the combined effects of fluctuations in the initial collision geometry and finite viscosity in the evolving medium.Comment: 384 authors, 71 institutions, 11 pages, 9 figures, and 2 tables.

Azimuthal anisotropy of neutral pion production in Au+Au collisions at sqrt(s_NN) = 200 GeV: Path-length dependence of jet quenching and the role of initial geometry

We have measured the azimuthal anisotropy of pi0's for 1 < pT < 18 GeV/c for Au+Au collisions at sqrt s_NN = 200 GeV. The observed anisotropy shows a gradual decrease in 3 < pT < 7 - 10 GeV/c, but remains positive beyond 10 GeV/c. The magnitude of this anisotropy is under-predicted, up to at least 10 GeV/c, by current perturbative QCD (pQCD) energy-loss model calculations. An estimate of the increase in anisotropy expected from initial-geometry modification due to gluon saturation effects and initial-geometry fluctuations is insufficient to account for this discrepancy. Calculations which implement a path length dependence steeper than what is implied by current pQCD energy-loss models, show reasonable agreement with the data.Comment: 384 authors, 6 pages text, 3 figures.
