Arts Funding Snapshot: GIA's Annual Research on Support for Arts and Culture, 2014

Foundation Center offers these key findings from GIA's thirteenth snapshot of foundation giving to arts and culture. The definition of arts and culture used for this snapshot is based on the National Taxonomy of Exempt Entities and encompasses funding for the performing arts, museums, visual arts, multidisciplinary arts, media and communications, humanities, and historical preservation. Most importantly, the findings tell us about the changes in foundation giving for the arts between 2011 and 2012 by a matched set of 714 funders and the distribution of 2012 arts and culture giving by the 1,000 largest US foundations by total giving.1 They are based on all arts grants of $10,000 or more reported to Foundation Center by these sets of the largest US foundations, hereafter referred to as "the sample".2 The Center has conducted annual examinations of the giving patterns of the nation's largest foundations for close to four decades

Observational implications of lowering the LIGO-Virgo alert threshold

The recent detection of the binary-neutron-star merger associated with GW170817 by both the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo and the network of electromagnetic-spectrum observing facilities around the world has made the multi-messenger detection of gravitational-wave (GW) events a reality. These joint detections allow us to probe GW sources in greater detail and provide us with the possibility of confidently establishing events that would not have been detected in GW data alone. In this Letter, we explore the prospects of using the electromagnetic (EM) follow-up of low-significance GW event candidates to increase the sample of confident detections with EM counterparts. We find that the GW-alert threshold change that would roughly double the number of detectable astrophysical events would increase the false-alarm rate (FAR) by more than five orders of magnitude from 1 per 100 years to more than 1000 per year. We find that the localization costs of following up low-significance candidates are marginal, as the same changes to FAR only increase distance/area localizations by less than a factor of 2 and increase volume localization by less than a factor of 4. We argue that EM follow-up thresholds for low-significance candidates should be set on the basis of alert purity (P_(astro)) and not FAR. Ideally, such estimates of P_(astro) would be provided by LIGO-Virgo, but in their absence we provide estimates of the average purity of the GW candidate alerts issued by LIGO-Virgo as a function of FAR for various LIGO-Virgo observing epochs

Weak spatial-genetic structure in a native invasive, the southern pine beetle (Dendroctonus frontalis), across the eastern United States

The southern pine beetle, Dendroctonus frontalis, is a native pest of pine trees that has recently expanded its range into the northeastern United States. Understanding its colonization, dispersal, and connectivity will be critical for mitigating negative economic and ecological impacts in the newly invaded areas. Characterization of spatial-genetic structure can contribute to this; however, previous studies have reached different conclusions about regional population genetic structure, with one study reporting a weak east-west pattern, and the most recent reporting an absence of structure. Here we systematically assessed several explanations for the absence of spatial-genetic structure. To do this, we developed nine new microsatellite markers and combined them with an existing 24-locus data matrix for the same individuals. We then reanalyzed this full dataset alongside datasets in which certain loci were omitted with the goal of creating more favorable signal to noise ratios. We also partitioned the data based on the sex of D. frontalis individuals, and then employed a broad suite of genotypic clustering and isolation-by-distance (IBD) analyses. We found that neither inadequate information content in the molecular marker set, nor unfavorable signal-to-noise ratio, nor insensitivity of the analytical approaches could explain the absence of structure. Regardless of dataset composition, there was little evidence for clusters (i.e., distinct geo-genetic groups) or clines (i.e., gradients of increasing allele frequency differences over larger geographic distances), with one exception: significant IBD was repeatedly detected using an individual-based measure of relatedness whenever datasets included males (but not for female-only datasets). This is strongly indicative of broad-scale female-biased dispersal, which has not previously been reported for D. frontalis, in part owing to logistical limitations of direct approaches (e.g., capture-mark-recapture). Weak spatial-genetic structure suggests long-distance connectivity and that gene flow is high, but additional research is needed to understand range expansion and outbreak dynamics in this species using alternate approaches

Ubercalibration of the Deep Lens Survey

We describe the internal photometric calibration of the Deep Lens Survey, which consists of five widely separated fields observed by two different observatories. Adopting the global linear least-squares ("ubercal") approach developed for the Sloan Digital Sky Survey (SDSS), we derive flatfield corrections for all observing runs, which indicate that the original sky flats were nonuniform by up to 0.13 mag peak to valley in \z band, and by up to half that amount in {\it BVR}. We show that application of these corrections reduces spatial nonuniformities in corrected exposures to the 0.01-0.02 mag level. We conclude with some lessons learned in applying ubercal to a survey structured very differently from SDSS, with isolated fields, multiple observatories, and shift-and-stare rather than drift-scan imaging. Although the size of the error caused by using sky or dome flats is instrument- and wavelength-dependent, users of wide-field cameras should not assume that it is small. Pipeline developers should facilitate routine application of this procedure, and surveys should include it in their plans from the outset.Comment: accepted to MNRA

Student experiences and perceptions of compulsory research projects: a veterinary perspective

Background Although research underpins clinical work, many students training to be clinicians are not inherently interested in developing research skills. Aim To characterise and understand veterinary student experiences and perceptions of compulsory research projects. Methods This was an explanatory sequential mixed-methods study, with a questionnaire survey of an entire cohort informing purposive selection for focus group discussions. Student views were triangulated with staff questionnaire data. Results About a third of the cohort felt that the project had not been worthwhile or had not fostered useful skills. Focus group data analysis identified fragility of motivation and lack of clear schemata for the research process as key themes. Students were easily demotivated by typical research challenges and lack of schemata contributed to a poor understanding of the rationale for the project, encouraging highly extrinsic forms of motivation. Triangulation with staff questionnaire data indicated that staff understood students’ challenges, but were more likely than students to consider it to be a valuable learning experience. Conclusions Findings support ongoing curriculum development and emphasise that, to optimise motivation, engagement and learning, students training to be clinicians need a clear rationale for research, based on development of critical inquiry skills as a core clinical competency
