The Influence of Disciplinary Background on Peer Reviewers’ Evaluations of Engineering Education Journal Manuscripts

This is the first of a series of studies that explore the relationship between disciplinary background and the weighting of various elements of a manuscript in peer reviewers’ determination of publication recommendations. Research questions include: (1) To what extent are tacit criteria for determining quality or value of EER manuscripts influenced by reviewers’ varied disciplinary backgrounds and levels of expertise? and (2) To what extent does mentored peer review professional development influence reviewers’ EER manuscript evaluations? Data were collected from 27 mentors and mentees in a peer review professional development program. Participants reviewed the same two manuscripts, using a form to identify strengths, weaknesses, and recommendations. Responses were coded by two researchers (70% IRR). Our findings suggest that disciplinary background influences reviewers’ evaluation of EER manuscripts. We also found evidence that professional development can improve reviewers’ understanding of EER disciplinary conventions. Deeper understanding of the epistemological basis for manuscript reviews may reveal ways to strengthen professional preparation in engineering education as well as other disciplines

Building a Community of Mentors in Engineering Education Research Through Peer Review Training

Peer review of scholarship is critical to the advancement of knowledge in a scholarly discipline. Despite this, scholars receive little or no training in effective and constructive peer review. The process of peer review has been routinely criticized in higher education for lack of quality reviews and reviewers, and reviews that are personal and not constructive. As a discipline, engineering education research (EER) benefits from diverse disciplinary backgrounds and perspectives of scholars, and as such relies on peer review of scholarship to generate, interpret, and translate knowledge. Supported by funding through the National Science Foundation, this project is developing, implementing, and assessing a project that conducts training in EER peer review for journal articles and grant proposals. This paper describes the Engineering Education Research Peer Review Training (EER PERT) project, which is designed to develop EER scholars’ peer review skills through mentored reviewing experiences. The overall goals of the EER PERT project are twofold: to establish, assess and evaluate a mentored reviewer program for 1) EER journal manuscripts and 2) EER grant proposals. In the first year of the project, two cohorts have participated in the mentored EER journal manuscript program through partnership with the Journal of Engineering Education (JEE), where triads (two mentees and one mentor) work collaboratively to review three manuscripts. Triads work with coaches informally to provide feedback on their experience and discuss manuscripts they are reviewing. Across the two cohorts, 42 mentees have collaborated with 18 mentors and 3 coaches, with some mentors and coaches participating in both cohorts. Project evaluation activities for the mentored manuscript review program included focus groups and exit surveys with both mentees and mentors in the first cohort. The main findings from the evaluation of the first cohort included the following themes: 1) the program provided valuable training and increased participant’s confidence in conducting EER scholarship, 2) the program fostered a sense of community and inclusion, particularly for those without EER backgrounds and from outside the US, and 3) program logistics could create barriers for participants, including working across time zones and tracking triad progress. Two main changes were implemented for the second cohort, including 1) a program dashboard for teams to track progress and organize update form submissions and 2) an optional monthly discussion meeting to supplement initial program orientation and triad meetings. The monthly discussions are intended to provide additional training in peer review topics and develop community among participants through networking opportunities. Planned discussion topics include updated JEE Author Guidelines and Review Criteria, inclusive language in scholarly publications, anti-racism in peer review, getting involved with the EER community, and roles and processes within the JEE Editorial Board. Program evaluation of the mentored manuscript review program is being leveraged to develop a mentored grant proposal review program wherein participants will work with former NSF program officers to review six grant proposals and participate in a mock review panel. This paper will present an overview of the journal manuscript and proposal mentored reviewer programs and findings from program evaluation

Identifying Best Practices for Management of Electric Scooters

Course Code: AEDE 4567The purpose of this project was to conduct an analysis of the usage of rentable electric scooters (eScooters) and to identify any potential areas of safety concern regarding the usage of the eScooters within the City of Columbus. From there, we benchmarked Columbus to other cities based on policy regulations concerning the status of eScooters. We could then offer the City policy recommendations in order to properly manage the eScooters. This project was conducted in partnership with SMART Columbus and The Ohio State University.SMART ColumbusAcademic Major: Environment, Economy, Development, and Sustainabilit

Patterns of cell movement within the Dictyostelium slug revealed by cell type-specific, surface labeling of living cells

There are cells acattered in the rear, prespore region of the Dictyostelium slug that share many of the properties of the prestalk cells and that are therefore called anterior-like cells (ALCs). By placing the gene encoding a cell surface protein under the control of an ALC-specific promoter and immunologically labeling the living cells, we analyze the movement of ALCs within the slug. There is a posterior to anterior cellular flow, and the ALCs change their movement pattern as they enter the prestalk zone. Prestalk cells are periodically shed from the migrating slug. They must be replaced if the correct ratio of prestalk to prespore cells is to be maintained, and we present evidence for the trans-differentiation of prespore into prestalk cells, with ALCs functioning as intermediates in the transition. The slug has, therefore, a surprisingly dynamic structure, both with respect to cellular differentiation and cell movement

The Comprehensive Native Interactome of a Fully Functional Tagged Prion Protein

The enumeration of the interaction partners of the cellular prion protein, PrPC, may help clarifying its elusive molecular function. Here we added a carboxy proximal myc epitope tag to PrPC. When expressed in transgenic mice, PrPmyc carried a GPI anchor, was targeted to lipid rafts, and was glycosylated similarly to PrPC. PrPmyc antagonized the toxicity of truncated PrP, restored prion infectibility of PrPC-deficient mice, and was physically incorporated into PrPSc aggregates, indicating that it possessed all functional characteristics of genuine PrPC. We then immunopurified myc epitope-containing protein complexes from PrPmyc transgenic mouse brains. Gentle differential elution with epitope-mimetic decapeptides, or a scrambled version thereof, yielded 96 specifically released proteins. Quantitative mass spectrometry with isotope-coded tags identified seven proteins which co-eluted equimolarly with PrPC and may represent component of a multiprotein complex. Selected PrPC interactors were validated using independent methods. Several of these proteins appear to exert functions in axomyelinic maintenance

Computational Models of Stellar Collapse and Core-Collapse Supernovae

Core-collapse supernovae are among Nature's most energetic events. They mark the end of massive star evolution and pollute the interstellar medium with the life-enabling ashes of thermonuclear burning. Despite their importance for the evolution of galaxies and life in the universe, the details of the core-collapse supernova explosion mechanism remain in the dark and pose a daunting computational challenge. We outline the multi-dimensional, multi-scale, and multi-physics nature of the core-collapse supernova problem and discuss computational strategies and requirements for its solution. Specifically, we highlight the axisymmetric (2D) radiation-MHD code VULCAN/2D and present results obtained from the first full-2D angle-dependent neutrino radiation-hydrodynamics simulations of the post-core-bounce supernova evolution. We then go on to discuss the new code Zelmani which is based on the open-source HPC Cactus framework and provides a scalable AMR approach for 3D fully general-relativistic modeling of stellar collapse, core-collapse supernovae and black hole formation on current and future massively-parallel HPC systems. We show Zelmani's scaling properties to more than 16,000 compute cores and discuss first 3D general-relativistic core-collapse results.Comment: 16 pages, 5 figures, to appear in the proceedings of the DOE/SciDAC 2009 conference.

Diurnal timing of nonmigratory movement by birds: the importance of foraging spatial scales

Timing of activity can reveal an organism's efforts to optimize foraging either by minimizing energy loss through passive movement or by maximizing energetic gain through foraging. Here, we assess whether signals of either of these strategies are detectable in the timing of activity of daily, local movements by birds. We compare the similarities of timing of movement activity among species using six temporal variables: start of activity relative to sunrise, end of activity relative to sunset, relative speed at midday, number of movement bouts, bout duration and proportion of active daytime hours. We test for the influence of flight mode and foraging habitat on the timing of movement activity across avian guilds. We used 64 570 days of GPS movement data collected between 2002 and 2019 for local (non‐migratory) movements of 991 birds from 49 species, representing 14 orders. Dissimilarity among daily activity patterns was best explained by flight mode. Terrestrial soaring birds began activity later and stopped activity earlier than pelagic soaring or flapping birds. Broad‐scale foraging habitat explained less of the clustering patterns because of divergent timing of active periods of pelagic surface and diving foragers. Among pelagic birds, surface foragers were active throughout all 24 hrs of the day while diving foragers matched their active hours more closely to daylight hours. Pelagic surface foragers also had the greatest daily foraging distances, which was consistent with their daytime activity patterns. This study demonstrates that flight mode and foraging habitat influence temporal patterns of daily movement activity of birds.We thank the Nature Conservancy, the Bailey Wildlife Foundation, the Bluestone Foundation, the Ocean View Foundation, Biodiversity Research Institute, the Maine Outdoor Heritage Fund, the Davis Conservation Foundation and The U.S. Department of Energy (DE‐EE0005362), and the Darwin Initiative (19-026), EDP S.A. ‘Fundação para a Biodiversidade’ and the Portuguese Foundation for Science and Technology (FCT) (DL57/2019/CP 1440/CT 0021), Enterprise St Helena (ESH), Friends of National Zoo Conservation Research Grant Program and Conservation Nation, ConocoPhillips Global Signature Program, Maryland Department of Natural Resources, Cellular Tracking Technologies and Hawk Mountain Sanctuary for providing funding and in-kind support for the GPS data used in our analyses

Measurement of the nuclear modification factor for muons from charm and bottom hadrons in Pb+Pb collisions at 5.02 TeV with the ATLAS detector

Heavy-flavour hadron production provides information about the transport properties and microscopic structure of the quark-gluon plasma created in ultra-relativistic heavy-ion collisions. A measurement of the muons from semileptonic decays of charm and bottom hadrons produced in Pb+Pb and pp collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV with the ATLAS detector at the Large Hadron Collider is presented. The Pb+Pb data were collected in 2015 and 2018 with sampled integrated luminosities of 208 mu b(-1) and 38 mu b(-1), respectively, and pp data with a sampled integrated luminosity of 1.17 pb(-1) were collected in 2017. Muons from heavy-flavour semileptonic decays are separated from the light-flavour hadronic background using the momentum imbalance between the inner detector and muon spectrometer measurements, and muons originating from charm and bottom decays are further separated via the muon track's transverse impact parameter. Differential yields in Pb+Pb collisions and differential cross sections in pp collisions for such muons are measured as a function of muon transverse momentum from 4 GeV to 30 GeV in the absolute pseudorapidity interval vertical bar eta vertical bar < 2. Nuclear modification factors for charm and bottom muons are presented as a function of muon transverse momentum in intervals of Pb+Pb collision centrality. The bottom muon results are the most precise measurement of b quark nuclear modification at low transverse momentum where reconstruction of B hadrons is challenging. The measured nuclear modification factors quantify a significant suppression of the yields of muons from decays of charm and bottom hadrons, with stronger effects for muons from charm hadron decays
