Transforming Criminal Justice Internships into Capstone Courses: A Response to the Challenges of the COVID-19 Crisis
The COVID-19 pandemic in March 2020 resulted in the declaration of a national emergency that closed universities across the nation. With no warning, faculty were required to move classes from face-to-face to completely online instruction. This situation posed many difficulties, but particularly for faculty who were teaching and supervising students completing internships. Interns were removed from their internships abruptly as agencies and departments moved to essential personnel only. Faculty scrambled to create online learning experiences that met academic learning outcomes and the goals of criminal justice students enrolled in these courses. This paper details our experiences with these challenges, particularly as we revised criminal justice internship courses and developed capstone courses to replace face-to-face internship experiences. While the challenges we faced involved criminal justice internships, they were not unique to the major, and the approaches taken and lessons learned are likely applicable to a host of disciplines

Teacher Immediacy Behaviors and Studentsâ Public Speaking Anxiety: More and Less Helpful than Anticipated
Public speaking anxiety inhibits students in the basic course classroom, whether face-to-face, hybrid or online, and beyond. Equipping instructors with the tools necessary to empower students to manage that anxiety and excel in their basic communication course is a goal of scholars and practitioners. In this study, the researchers examine applying and testing a math anxiety model (i.e., Kelly at al., 2015) to the challenge of public speaking anxiety. We expanded the original model by examining instructor verbal immediate behaviors alongside their nonverbal immediate behaviors. We also tested the Instructional Beliefs Model (IBM; Weber et al., 2011), which indicates that student beliefs (i.e., perceived immediacy mediates the relationship between student characteristics (i.e., intrinsic motivation) and instructor behaviors (i.e., verbal and nonverbal immediate behaviors) and the instructional outcome (i.e., public speaking anxiety) The data best fit the adapted math anxiety model; however, the influences were extremely low. This calls into question whether instructor immediate behaviors and student public speaking anxiety have been examined together many times before, but never published due to statistically insignificant results or low effect sizes
Student and Faculty Perceptions of the Impact of Masks on Student Learning and Communication in the Classroom
As a result of the COVID-19 pandemic, facemask requirements while indoors were implemented in colleges and universities, both in the United States and beyond. Empirical evidence has shown that such mandates improved the health and safety of students, faculty, staff, and administrators. However, the impacts of such precautions on student learning and communication have to date gone largely unexplored. The current study surveyed students and faculty at one regional midwestern institution to assess their perceptions on the impact of masks on student learning and communication in the classroom. Findings are included, followed by a discussion of their implications

Effects of Short- and Long-Term Variation in Resource Conditions on Soil Fungal Communities and Plant Responses to Soil Biota
Soil biota can strongly influence plant performance with effects ranging from negative to positive. However, shifts in resource availability can influence plant responses, with soil pathogens having stronger negative effects in high-resource environments and soil mutualists, such as arbuscular mycorrhizal fungi (AMF), having stronger positive effects in low-resource environments. Yet the relative importance of long-term vs. short-term variation in resources on soil biota and plant responses is not well-known. To assess this, we grew the perennial herb Asclepias speciosa in a greenhouse experiment that crossed a watering treatment (wet vs. dry treatment) with a manipulation of soil biota (live vs. sterilized soil) collected from two geographic regions (Washington and Minnesota) that vary greatly in annual precipitation. Because soil biota can influence many plant functional traits, we measured biomass as well as resource acquisition (e.g., root:shoot, specific leaf area) and defense (e.g., trichome and latex production) traits. Due to their important role as mutualists and pathogens, we also characterized soil fungal communities in the field and greenhouse and used curated databases to assess fungal composition and potential function. We found that the experimental watering treatment had a greater effect than soil biota origin on plant responses; most plant traits were negatively affected by live soils under wet conditions, whereas responses were neutral or positive in live dry soil. These consistent differences in plant responses occurred despite clear differences in soil fungal community composition between inoculate origin and watering treatments, which indicates high functional redundancy among soil fungi. All plants grown in live soil were highly colonized by AMF and root colonization was higher in wet than dry soil; root colonization by other fungi was low in all treatments. The most parsimonious explanation for negative plant responses in wet soil is that AMF became parasitic under conditions that alleviated resource limitation. Thus, plant responses appeared driven by shifts within rather than between fungal guilds, which highlights the importance of coupling growth responses with characterizations of soil biota to fully understand underlying mechanisms. Collectively these results highlight how short-term changes in environmental conditions can mediate complex interactions between plants and soil biota
Barriers to ideal outcomes after pediatric liver transplantation
Longâterm survival for children who undergo LT is now the rule rather than the exception. However, a focus on the outcome of patient or graft survival rates alone provides an incomplete and limited view of life for patients who undergo LT as an infant, child, or teen. The paradigm has now appropriately shifted to opportunities focused on our overarching goals of âsurviving and thrivingâ with longâterm allograft health, freedom of complications from longâterm immunosuppression, selfâreported wellâbeing, and global functional health. Experts within the liver transplant community highlight clinical gaps and potential barriers at each of the pretransplant, intraâoperative, earlyâ, mediumâ, and longâterm postâtransplant stages toward these broader mandates. Strategies including clinical research, innovation, and quality improvement targeting both traditional as well as PRO are outlined and, if successfully leveraged and conducted, would improve outcomes for recipients of pediatric LT.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151257/1/petr13537.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151257/2/petr13537_am.pd
A core outcome domain set for clinical research on capillary malformations (the COSCAM project):an e-Delphi process and consensus meeting
BACKGROUND: There is limited evidence on the best available treatment options for capillary malformations (CMs), mainly due to the absence of uniform outcome measures in trials on therapies. A core outcome set (COS) enables standard reporting of trial outcomes, which facilitates comparison of treatment results. OBJECTIVES: To develop a core outcome domain set (CDS), as part of a core outcome set (COS), for clinical research on CMs. METHODS: Sixtyâseven potentially relevant outcome subdomains were recognized based on the literature, focus group sessions, and input from the COSCAM working group. These outcome subdomains were presented in an online Delphi study to CM experts (medical specialists and authors of relevant literature) and (parents of) patients with CM (international patient associations). During three eâDelphi study rounds, the participants repeatedly scored the importance of these outcome subdomains on a sevenâpoint Likert scale. Participants could also propose other relevant outcome subdomains. Consensus was defined as â„ 80% agreement as to the importance of an outcome subdomain among both stakeholder groups. The CDS was finalized during an online consensus meeting. RESULTS: In total 269 participants from 45 countries participated in the first eâDelphi study round. Of these, 106 were CM experts from 32 countries, made up predominantly of dermatologists (59%) and plastic surgeons (18%). Moreover, 163 (parents of) patients with CM from 28 countries participated, of whom 58% had SturgeâWeber syndrome. During the two subsequent eâDelphi study rounds, 189 and 148 participants participated, respectively. After the entire consensus process, consensus was reached on 11 outcome subdomains: colour/redness, thickness, noticeability, distortion of anatomical structures, glaucoma, overall healthârelated quality of life, emotional functioning, social functioning, tolerability of intervention, patient satisfaction with treatment results, and recurrence. CONCLUSIONS: We recommend the CDS to be used as a minimum reporting standard in all future trials of CM therapy. Our next step will be to select suitable outcome measurement instruments to score the core outcome subdomains. What is already known about this topic? Besides physical and functional sequelae, capillary malformations (CMs) often cause emotional and social burden. The lack of uniform outcome measures obstructs proper evaluation and comparison of treatment strategies. As a result, there is limited evidence on the best available treatment options. The development of a core outcome set (COS) may improve standardized reporting of trial outcomes. What does this study add? A core outcome domain set (CDS), as part of a COS, was developed for clinical research on CMs. International consensus was reached on the recommended core outcome subdomains to be measured in CM trials: colour/redness, thickness, noticeability, distortion of anatomical structures, glaucoma, overall healthârelated quality of life, emotional functioning, social functioning, tolerability of intervention, patient satisfaction with treatment results, and recurrence. This CDS enables the next step in the development of a COS, namely to reach consensus on the core outcome measurement instruments to score the core outcome subdomains. What are the clinical implications of this work? The obtained CDS will facilitate standardized reporting of treatment outcomes, thereby enabling proper comparison of treatment results. This comparison is likely to provide more reliable information for patients about the best available treatment options
Jet energy measurement with the ATLAS detector in proton-proton collisions at root s=7 TeV
The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of âs = 7TeV corresponding to an integrated luminosity of 38 pb-1. Jets are reconstructed with the anti-kt algorithm with distance parameters R=0. 4 or R=0. 6. Jet energy and angle corrections are determined from Monte Carlo simulations to calibrate jets with transverse momenta pTâ„20 GeV and pseudorapidities {pipe}η{pipe}<4. 5. The jet energy systematic uncertainty is estimated using the single isolated hadron response measured in situ and in test-beams, exploiting the transverse momentum balance between central and forward jets in events with dijet topologies and studying systematic variations in Monte Carlo simulations. The jet energy uncertainty is less than 2. 5 % in the central calorimeter region ({pipe}η{pipe}<0. 8) for jets with 60â€pT<800 GeV, and is maximally 14 % for pT<30 GeV in the most forward region 3. 2â€{pipe}η{pipe}<4. 5. The jet energy is validated for jet transverse momenta up to 1 TeV to the level of a few percent using several in situ techniques by comparing a well-known reference such as the recoiling photon pT, the sum of the transverse momenta of tracks associated to the jet, or a system of low-pT jets recoiling against a high-pT jet. More sophisticated jet calibration schemes are presented based on calorimeter cell energy density weighting or hadronic properties of jets, aiming for an improved jet energy resolution and a reduced flavour dependence of the jet response. The systematic uncertainty of the jet energy determined from a combination of in situ techniques is consistent with the one derived from single hadron response measurements over a wide kinematic range. The nominal corrections and uncertainties are derived for isolated jets in an inclusive sample of high-pT jets. Special cases such as event topologies with close-by jets, or selections of samples with an enhanced content of jets originating from light quarks, heavy quarks or gluons are also discussed and the corresponding uncertainties are determined. © 2013 CERN for the benefit of the ATLAS collaboration
Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector
The inclusive and dijet production cross-sections have been measured for jets
containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass
energy of sqrt(s) = 7 TeV, using the ATLAS detector at the LHC. The
measurements use data corresponding to an integrated luminosity of 34 pb^-1.
The b-jets are identified using either a lifetime-based method, where secondary
decay vertices of b-hadrons in jets are reconstructed using information from
the tracking detectors, or a muon-based method where the presence of a muon is
used to identify semileptonic decays of b-hadrons inside jets. The inclusive
b-jet cross-section is measured as a function of transverse momentum in the
range 20 < pT < 400 GeV and rapidity in the range |y| < 2.1. The bbbar-dijet
cross-section is measured as a function of the dijet invariant mass in the
range 110 < m_jj < 760 GeV, the azimuthal angle difference between the two jets
and the angular variable chi in two dijet mass regions. The results are
compared with next-to-leading-order QCD predictions. Good agreement is observed
between the measured cross-sections and the predictions obtained using POWHEG +
Pythia. MC@NLO + Herwig shows good agreement with the measured bbbar-dijet
cross-section. However, it does not reproduce the measured inclusive
cross-section well, particularly for central b-jets with large transverse
momenta.Comment: 10 pages plus author list (21 pages total), 8 figures, 1 table, final
