This qualitative study used interviews with editors at college newspapers throughout Florida to better understand the close-knit relationships they have with members of the college community and whether these journalists take advantage of these connections as newsgatherers. The study found that editors' strong personal relationships with fellow students and members of the college community do often help them find and develop stories that are newsworthy and relevant to their readership. In addition, editors interviewed recognize this advantage and use naturally strong community connections as an "insider advantage" as they go about their work.Includes bibliographical references

Controlled Release Characteristics of Aqueous PEO‐PPO‐PEO Micelles With Added Malachite Green, Erythrosin, and Cisplatin Determined by UV–Visible Spectroscopy

Dynamic diffusion experiments were performed on aqueous polymeric micelles mixed with malachite green (0.05% mass v−1), erythrosin (0.1% mass v−1), and cisplatin (0.1% mass v−1) to gauge release from sequestered structures using ultraviolet–visible spectroscopy. The additives were formulated with 20% mass v−1 aqueous solutions of polyethylene oxide‐polypropylene oxide‐polyethylene oxide, PEO‐PPO‐PEO (F127). Each additive was tested neat at room temperature, neat at 40 °C, and formulated with F127 at room temperature, and 40 °C. After constructing calibration curves, the dynamic release for each ternary additive and corresponding diffusion coefficients were calculated. Results show that F127 retards permeation at room temperature. In general, the neat additives at 40 °C showed the highest permeability for both malachite green and erythrosin. Malachite green released almost 90% of the dye by 60 min of permeation. When formulated with F127 at 40 °C, sizeable release was still noted, but with an induction period of 10–30 min to register release. The behavior with cisplatin was more complicated as the first 5 h of permeation resulted in a burst delivery with cisplatin (6% total release with cisplatin‐F127‐RT compared to 4% total release cisplatin‐RT) but with overall lower release. The higher fluence at elevated temperature is attributed to reducing the blocking effect of the amphiphiles on the walls of the dialysis tubing as they are directed to form colloidal gels. There is also likely a correlation between higher temperature and higher overall permeability if the membrane pores also expand with temperature.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/142528/1/jsde12001.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/142528/2/jsde12001_am.pd

Psychological Flexibility as Shared Process of Change in Acceptance and Commitment Therapy and Exposure and Response Prevention for Obsessive-Compulsive Disorder: A Singe Case Design Study

Changes in psychological flexibility were tracked in a combined protocol of exposure and response prevention (ERP) and acceptance and commitment therapy (ACT) for adults with OCD to assess if changes in psychological flexibility processes were unique to ACT intervention (e.g., not impacted by ERP). Using a non-concurrent multiple baseline design, four participants received sessions of ERP and ACT while data was collected on psychological flexibility processes of change and OCD symptom severity. Results indicate treatment response for three of four participants based on OCD scores. Contrary to predictions, data suggest both ERP and ACT have positive effects on psychological flexibility. Implications of these findings are discussed in relation to recent research on ACT and ERP for OCD. This study also illustrates a type of research design that can be accomplished in clinical practice

LAURA Users Manual: 5.6

This users manual provides in-depth information concerning installation and execution of Laura, version 5. Laura is a structured, multiblock, computational aerothermodynamic simulation code. Version 5 represents a major refactoring of the original Fortran 77 Laura code toward a modular structure afforded by Fortran 95. The refactoring improved usability and maintainability by eliminating the requirement for problem-dependent recompilations, providing more intuitive distribution of functionality, and simplifying inter- faces required for multi-physics coupling. As a result, Laura now shares gas-physics modules, MPI modules, and other low-level modules with the Fun3D unstructured-grid code. In addition to internal refactoring, several new features and capabilities have been added, e.g., a GNU-standard installation process, parallel load balancing, automatic trajectory point sequencing, free-energy minimization, and coupled ablation and flow field radiation

Proto-Neutron Star Winds with Magnetic Fields and Rotation

We solve the 1D neutrino-heated non-relativistic MHD wind problem for conditions that range from slowly rotating (spin period P > 10 ms) protoneutron stars (PNSs) with surface field strengths typical of radio pulsars (B < 10^13 G), to "proto-magnetars" with B ~ 10^14-10^15 G in their hypothesized rapidly rotating initial states (P ~ 1 ms). We use the simulations of Bucciantini et al. (2006) to map our monopole results onto a more physical dipole geometry and to estimate the spindown of PNSs when their winds are relativistic. We then quantify the effects of rotation and magnetic fields on the mass loss, energy loss, and r-process nucleosynthesis in PNS winds. We describe the evolution of PNS winds through the Kelvin-Helmholtz cooling epoch, emphasizing the transition between (1) thermal neutrino-driven, (2) non-relativistic magnetically-dominated, and (3) relativistic magnetically-dominated outflows. We find that proto-magnetars with P ~ 1 ms and B > 10^15 G drive relativistic winds with luminosities, energies, and Lorentz factors (magnetization sigma ~ 0.1-1000) consistent with those required to produce long duration gamma-ray bursts and hyper-energetic supernovae (SNe). A significant fraction of the rotational energy may be extracted in only a few seconds, sufficiently rapidly to alter the asymptotic energy of the SN remnant, its morphology, and, potentially, its nucleosynthetic yield. Winds from PNSs with more modest rotation periods (2 - 10 ms) and with magnetar-strength fields produce conditions significantly more favorable for the r-process than winds from slowly rotating PNSs. Lastly, we show that energy and momentum deposition by convectively-excited waves further increase the likelihood of successful r-process in PNS winds.Comment: 21 pages, 12 figures, final version accepted to Ap

Blood Flow Restriction Training After Patellar INStability (BRAINS Trial)

Background Patellar instability is a common and understudied condition that disproportionally affects athletes and military personnel. The rate of post-traumatic osteoarthritis that develops following a patellar dislocation can be up to 50% of individuals 5–15 years after injury. Conservative treatment is the standard of care for patellar instability however, there are no evidence-informed rehabilitation guidelines in the scientific literature. The purpose of this study is to assess the effectiveness of blood-flow restriction training (BFRT) for patellar instability. Our hypotheses are that this strategy will improve patient-reported outcomes and accelerate restoration of symmetric strength and knee biomechanics necessary to safely return to activity. Methods/Design This is a parallel-group, superiority, randomized, double-blinded, placebo-controlled clinical trial at the University of Kentucky, sports medicine clinic that aims to recruit 78 patients with acute patellar dislocations randomly allocated into two groups: (1) sham BFRT and (2) BFRT. Both groups will receive the current standard of care physical therapy 3 times per week for up to 9 weeks. Physical therapy sessions will consist of typical standard of care treatment followed by BFRT or sham BFRT. Primary outcomes include the Norwich Patellar Instability Scale, quadriceps strength, and imaging and biochemical biomarkers of cartilage degradation. Discussion The current standard of care for non-operative treatment of patellar instability is highly variable does not adequately address the mechanisms necessary to restore lower extremity function and protect the long-term health of articular cartilage following injury. This proposed novel intervention strategy uses an easily implementable therapy to evaluate if BFRT significantly improves patient-reported outcomes, function, and joint health over the first year of recovery.
