Introduction:
Despite the central importance of cross-disciplinary collaboration in the Clinical and Translational Science Award (CTSA) network and the implementation of various programs designed to enhance collaboration, rigorous evidence for the efficacy of these approaches is lacking. We conducted a novel randomized controlled trial (RCT; ClinicalTrials.gov identifier: NCT05395286) of a promising approach to enhance collaboration readiness and behavior among 95 early career scholars from throughout the CTSA network.
Methods:Participants were randomly assigned (within two cohorts) to participate in an Innovation Lab, a week-long immersive collaboration experience, or to a treatment-as-usual control group. Primary outcomes were change in metrics of self-reported collaboration readiness (through 12-month follow-up) and objective collaboration network size from bibliometrics (through 21 months); secondary outcomes included self-reported number of grants submitted and, among Innovation Lab participants only, reactions to the Lab experience (through 12 months).
Results:Short-term reactions from Innovation Lab participants were quite positive, and controlled evidence for a beneficial impact of Innovation Labs over the control condition was observed in the self-reported number of grant proposals in the intent-to-treat sample. Primary measures of collaboration readiness were near ceiling in both groups, limiting the ability to detect enhancement. Collaboration network size increased over time to a comparable degree in both groups.
Conclusions:The findings highlight the need for systematic intervention development research to identify efficacious strategies that can be implemented throughout the CTSA network to better support the goal of enhanced cross-disciplinary collaboration.

The Australian SKA Pathfinder (ASKAP) radio telescope has carried out a survey of the entire Southern Sky at 887.5 MHz. The wide area, high angular resolution, and broad bandwidth provided by the low-band Rapid ASKAP Continuum Survey (RACS-low) allow the production of a next-generation rotation measure (RM) grid across the entire Southern Sky. Here we introduce this project as Spectral and Polarisation in Cutouts of Extragalactic sources from RACS (SPICE-RACS). In our first data release, we image 30 RACS-low fields in Stokes I, Q, U at 25$^{\prime\prime}$ angular resolution, across 744–1032 MHz with 1 MHz spectral resolution. Using a bespoke, highly parallelised, software pipeline we are able to rapidly process wide-area spectro-polarimetric ASKAP observations. Notably, we use ‘postage stamp’ cutouts to assess the polarisation properties of 105912 radio components detected in total intensity. We find that our Stokes Q and U images have an rms noise of $\sim$80 $\unicode{x03BC}$Jy PSF$^{-1}$, and our correction for instrumental polarisation leakage allows us to characterise components with $\gtrsim$1% polarisation fraction over most of the field of view. We produce a broadband polarised radio component catalogue that contains 5818 RM measurements over an area of $\sim$1300 deg$^{2}$ with an average error in RM of $1.6^{+1.1}_{-1.0}$ rad m$^{-2}$, and an average linear polarisation fraction $3.4^{+3.0}_{-1.6}$ %. We determine this subset of components using the conditions that the polarised signal-to-noise ratio is $>$8, the polarisation fraction is above our estimated polarised leakage, and the Stokes I spectrum has a reliable model. Our catalogue provides an areal density of $4\pm2$ RMs deg$^{-2}$; an increase of $\sim$4 times over the previous state-of-the-art (Taylor, Stil, Sunstrum 2009, ApJ, 702, 1230). Meaning that, having used just 3% of the RACS-low sky area, we have produced the 3rd largest RM catalogue to date. This catalogue has broad applications for studying astrophysical magnetic fields; notably revealing remarkable structure in the Galactic RM sky. We will explore this Galactic structure in a follow-up paper. We will also apply the techniques described here to produce an all-Southern-sky RM catalogue from RACS observations. Finally, we make our catalogue, spectra, images, and processing pipeline publicly available.

Communal hunting of small game such as hares has probably occurred for 10,000 years in the Great Basin. Ethnohistoric accounts of the nineteenth century indicate that indigenous peoples communally hunted large game (e.g., pronghorn, mountain sheep, deer, bison) across much of western North America including the Plains, desert Southwest, California, and Great Basin subregions, during and immediately preceding the contact era. Research in the Plains subregion suggests that communal large game hunting occurred there prior to the adoption of the bow-and-arrow between ca. 1,500 and 2,000 years ago, and in fact may have occurred as early as 9,000 to 10,000 years ago. Nineteenth- and early twentieth-century ethnohistoric accounts suggest that communal pronghorn (Antilocapra americana) hunts involving the construction of a corral with associated wings were utilized by many Great Basin peoples at the time of historic contact. This paper asks: (1) did communal pronghorn hunts occur prior to the Protohistoric Period (before ca. 600 ¹⁴C B.P.) in the north-central Great Basin? (2) if so, how ancient is this practice? and (3) did the methods or behaviors of the participants of these communal hunts vary through time? Detailed analysis of sites containing dozens, and in many cases, hundreds of projectile points that predate ca. 600 ¹⁴C B.P. found in or near existing juniper branch corrals and wings suggest that communal pronghorn hunting has occurred for at least 4,000 to 5,000 years in the north-central Great Basin. Further, behavioral variability is seen through time in the material remains of these communal hunts, with earlier (Middle Archaic) communal kills characterized by greater use of local toolstone sources, gearing-up just prior to the kill, and perhaps a greater reliance on shooting the trapped pronghorn rather than clubbing compared to Protohistoric communal kills.
