Powerful Arts Education Practice

This document describes 10 dimensions of powerful arts education practice — building blocks for organizations that engage young people in this practice. It also shares examples of the kinds of things you might see and feel at an organization — indicators — that could let you know these dimensions are at play.A working group of arts education leaders illuminated these dimensions and indicators through a collaborative process co-facilitated by Sarah Crowell, an expert practioner, and Lauren Stevenson, a researcher. Stevenson synthesized the group's insights and elaborated emerging dimensions and indicators through interviews with additional arts education leaders and iterative feedback from the working group. Working group members and interviewees included youth participants, youth mentors, young alumni, teaching artists, program managers, and artistic and executive directors at organizations known for powerful arts education practice. The following dimensions and indicators reflect their collective wisdom.

The shaky foundations of simulating single-cell RNA sequencing data

BACKGROUND: With the emergence of hundreds of single-cell RNA-sequencing (scRNA-seq) datasets, the number of computational tools to analyze aspects of the generated data has grown rapidly. As a result, there is a recurring need to demonstrate whether newly developed methods are truly performant-on their own as well as in comparison to existing tools. Benchmark studies aim to consolidate the space of available methods for a given task and often use simulated data that provide a ground truth for evaluations, thus demanding a high quality standard results credible and transferable to real data. RESULTS: Here, we evaluated methods for synthetic scRNA-seq data generation in their ability to mimic experimental data. Besides comparing gene- and cell-level quality control summaries in both one- and two-dimensional settings, we further quantified these at the batch- and cluster-level. Secondly, we investigate the effect of simulators on clustering and batch correction method comparisons, and, thirdly, which and to what extent quality control summaries can capture reference-simulation similarity. CONCLUSIONS: Our results suggest that most simulators are unable to accommodate complex designs without introducing artificial effects, they yield over-optimistic performance of integration and potentially unreliable ranking of clustering methods, and it is generally unknown which summaries are important to ensure effective simulation-based method comparisons

Prospective Associations from Family-of-Origin Interactions to Adult Marital Interactions and Relationship Adjustment

To test the social learning-based hypothesis that marital conflict resolution patterns are learned in the family-of-origin, we used longitudinal, observational data to assess prospective associations between family conflict interaction patterns during adolescence and offspring’s later marital conflict interaction patterns. Forty-seven participants completed an observed family conflict resolution task with their parents at age 14. Seventeen years later, they completed an observed marital conflict interaction task with their spouse, as well as a measure of marital adjustment. As predicted, levels of hostility and positive engagement expressed by parents and adolescents during family interactions were prospectively linked with levels of hostility and positive engagement expressed by offspring and their spouses during marital interactions. Family-of-origin hostility was a particularly robust predictor of marital interaction behaviors; it predicted later marital hostility and engagement controlling for psychopathology and positive family-of-origin engagement. For men, family-of-origin hostility also predicted poorer marital adjustment, an effect that was mediated through hostility in marital interactions. These findings suggest a long-lasting influence of family communication patterns, particularly hostility, on offspring’s intimate communication and relationship functioning

Without Face-to-Face Limits: Using Online Modules to Expand Specialty Focused Residency EBM Instruction for the ACGME Milestone Project

Objective: The Accreditation Council for Graduate Medical Education (ACGME) Milestone Project has created the need for specialty focused, developmentally tiered and competency based evidence-based medicine (EBM) instruction. The University of North Carolina at Chapel Hill Health Sciences Library is extending current staff capacity for face-to-face sessions by creating online module templates that can be adapted to meet the specific needs of more residency programs. Method: Testing the effectiveness, quality and usability of the draft templates is part of the project development plan. The specialty focused EBM face-to-face instruction session of the Clinical Based Year (CBY) anesthesiology residents' Academic Medicine Rotation is the model for the online template. In order to be able to compare the validity of the online modules in comparison with face-to-face sessions, baseline data was gathered from a pre-test/post-test completed by the ten anesthesiology resident participants in the 2015 program. The pre-test/post-test included five knowledge questions and two self-perception questions. After the face-to-face session, the anesthesiology residents were asked to review the online module version of the instruction and answer a brief survey about ease of use and preferred learning mode. Results: Seven of ten residents increased their number of correct answers on the post-test. There were no perfect scores on the pre-test and five perfect scores on the post-test. Three of ten residents indicated a higher self-perceived comfort level for completing a PubMed EBM search. Two of ten residents had an increase level of agreement that their PubMed searching skills are sufficient. Seven of ten residents evaluated the online module and rated it as clearly organized and easy to understand and use. Four would prefer to learn and practice the EBM content in a group session with an instructor, two did not have a preference and one strongly preferred to learn online. Conclusion: Pre-test/post-test data confirmed face-to-face instruction had a positive impact on EBM knowledge and moderately improved self-perceived comfort with EBM searching. This baseline data will be used to compare with residents who only use the online format in the future. Positive feedback on ease of using the online module confirms that the template is functional. A more formal objective evaluation is planned. The variety of learning preferences within this small group indicates that face-to-face instruction is preferred by some, but that online modules will better meet the needs of others and appear to be an adequate way to expand our overall reach

Development and Validation of a Symptom-Based Activity Index for Adults With Eosinophilic Esophagitis

Standardized instruments are needed to assess the activity of eosinophilic esophagitis (EoE), to provide endpoints for clinical trials and observational studies. We aimed to develop and validate a patient-reported outcome (PRO) instrument and score, based on items that could account for variations in patients’ assessments of disease severity. We also evaluated relationships between patients’ assessment of disease severity and EoE-associated endoscopic, histologic, and laboratory findings
