The Effect of eWOM from Identity and Non-Identity Social Media on Movie Sales.

Social media platforms differ in the extent to which users reveal their identities, as well as users\u27 ability to detect others\u27 identities, both of which could lead to differential effects of social media generated word-of-mouth (eWOM) on actual consumer behavioral responses. Based on prior research on social identification, and relationship orientation of social networks in marketing, the authors examine whether eWOM on identity-focused (e.g., Facebook) and non-identity-focused (e.g., Youtube) platforms impact an objective consumer response variable: motion pictures box office sales. Using social media posts data for 58 randomly selected movie releases across all platforms during the period November 2014 - February 2017, the authors demonstrate that the overall volume of eWOM across all social media is positively associated with movie box office sales. The authors further find that eWOM on identity and nonidentity-focused platforms each have a positive effect on sales, and the magnitude of their effect is not significantly different, suggesting that both types of platforms merit attention from marketing managers

Integrating and evaluating interdisciplinary sustainability and STEM curriculum in geographical education: A case of three teaching modalities

The effectiveness of interdisciplinary sustainability curriculum remains understudied in geography education. Accordingly, we deployed and evaluated an interdisciplinary sustainability and STEM module for in-person and online sections of a fall 2018 Human Geography course. Results indicate that sustainability knowledge improved after the interdisciplinary curricular intervention irrespective of course modality. Another focus is to explore student reactions to teaching modality due to COVID-19 disruptions. Results indicate that online student sustainability knowledge also improved during COVID-19 (fall 2020). For students in a section converted from in-person to blended, sustainability knowledge did not improve. Implications are provided

Susceptibility Provision Enhances Effective De-escalation (SPEED): utilizing rapid phenotypic susceptibility testing in Gram-negative bloodstream infections and its potential clinical impact

Abstract Objectives We evaluated the performance and time to result for pathogen identification (ID) and antimicrobial susceptibility testing (AST) of the Accelerate Pheno™ system (AXDX) compared with standard of care (SOC) methods. We also assessed the hypothetical improvement in antibiotic utilization if AXDX had been implemented. Methods Clinical samples from patients with monomicrobial Gram-negative bacteraemia were tested and compared between AXDX and the SOC methods of the VERIGENE® and Bruker MALDI Biotyper® systems for ID and the VITEK® 2 system for AST. Additionally, charts were reviewed to calculate theoretical times to antibiotic de-escalation, escalation and active and optimal therapy Results ID mean time was 21 h for MALDI-TOF MS, 4.4 h for VERIGENE® and 3.7 h for AXDX. AST mean time was 35 h for VITEK® 2 and 9.0 h for AXDX. For ID, positive percentage agreement was 95.9% and negative percentage agreement was 99.9%. For AST, essential agreement was 94.5% and categorical agreement was 93.5%. If AXDX results had been available to inform patient care, 25% of patients could have been put on active therapy sooner, while 78% of patients who had therapy optimized during hospitalization could have had therapy optimized sooner. Additionally, AXDX could have reduced time to de-escalation (16 versus 31 h) and escalation (19 versus 31 h) compared with SOC. Conclusions By providing fast and reliable ID and AST results, AXDX has the potential to improve antimicrobial utilization and enhance antimicrobial stewardship

Pass/fail grading in medical school and impact on residency placement

Objective: There is a trend toward using pass/fail (P/F) grading in the first 2 years of medical school as it has been noted to improve student well-being and academic performance is not negatively impacted. It is important that medical students are afforded the best medical education possible to prepare them for residency placement. Thus, the purpose of this study was to evaluate the impact of P/F grading in medical school on residency placement. Methods: This study compared archival residency match data from two medical school classes. The Class of 2016 had tiered grading and the Class of 2017 had P/F grading in the first year of medical school. Doximity’s Residency Navigator was used to rank the residency programs and an independent samples t-test was calculated to determine if residency rankings differed by class. Results: The findings showed no statistically significant differences in residency placement when comparing a cohort of medical school graduates with tiered grading to a cohort with P/F grading in the first year of medical school. Conclusion: These findings may be useful to medical education leaders when making decisions about grading systems. Medical education leaders should consider implementing P/F grading into the first year of medical school

The Power of Community: The Role of Community-Based Organizations in Mitigating COVID-19-Related Impacts on Well-Being Among South Florida's Minoritized Populations

The rapid closure of schools and businesses during the COVID-19 pandemic has had a significant impact in South Florida, highlighting diverse challenges to community well-being. Community-based organizations (CBOs) have served as a source of support for community members, particularly in stressful times. Using a combination of quantitative and qualitative methods, and in collaboration with Breakthrough Miami, a CBO committed to addressing the educational opportunity gap in Miami-Dade County, we conducted a study to assess challenges to the well-being of systematically minoritized families during the heart of the COVID-19 pandemic. The study included longitudinal survey data collected via ecological momentary assessment and in-depth interviews with Breakthrough Miami families to gather richer and nuanced data regarding indicators of well-being and CBO engagement. Quantitative results indicated that as perceived stress increased over time, so too did emotional and informational support. Follow-up qualitative interviews indicated that 100% of families identified Breakthrough Miami as a source of academic support during the pandemic. Additionally, families cited the important role Breakthrough Miami played beyond their standard academic programs and services in coping with the most significant sources of stress reported through the pandemic: meeting basic needs and threats to socioemotional well-being. Implications for CBOs are addressed

Direct antimicrobial susceptibility testing of positive blood cultures: A comparison of the accelerate Pheno™ and VITEK® 2 systems

Objectives To compare the performance and time-to-result (TTR) for antimicrobial susceptibility testing (AST) of positive blood cultures (PBC) using the Accelerate Pheno™ system (AXDX) and both a direct VITEK® 2 card inoculation workflow (DV2) and traditional FDA-approved VITEK® 2 workflow using subcultured isolates (V2). Methods Patient samples with monomicrobial Gram-negative rod bacteremia were tested on AXDX and DV2 in tandem, and compared to V2 AST results. Categorical agreement (CA) errors were adjudicated using broth microdilution. Instrumentation times and AST TTR were compared. Results AXDX and DV2 had a CA of 91.5% and 97.4%, respectively, compared to V2. Post-adjudication, AXDX, DV2, and V2 had CA of 94.7%, 95.7% and 96.5%, respectively. Instrument run times were 6.6 h, 9.4 h, and 9.2 h, and AST TTR were 8.9 h, 12.9 h and 35.5 h, respectively. Conclusions AXDX and DV2 AST is fast and reliable, which may have significant antimicrobial stewardship implications
