RESUMEN
An organizational crisis is a low-probability, high-impact event that threatens the survival of organizations and individuals, often with little warning. In response, people seek clarity, reassurance, and hope from organiza-tional leaders. Yet, crises also vary in nature and impact (e.g., a product failure versus the COVID-19 pan-demic), which presents diverse challenges to leaders and differing stakeholder perceptions. Based on a critical analysis of 69 empirical articles, we provide a comprehensive, systematic, interdisciplinary review of the crisis leadership literature. Our review utilizes the Coombs and Holladay (1996) crisis typology, where crises are categorized according to mutually exclusive attributional dimensions (i.e., internal-external and intentional-unintentional). We conduct a thematic analysis of crisis leadership within and across these four cri-sis categories and find that each is associated with a different leadership theme. We also examine the method-ological quality and rigor of the qualitative and quantitative articles in our review. Based on our findings, we also offer suggestions to guide future crisis leadership research, and provide guidance for organizational lead-ers in how to respond to various crises.
RESUMEN
The development of SARS-CoV-2 vaccines during the COVID-19 pandemic has prompted the emergence of COVID-19 vaccine data. Timely access to COVID-19 vaccine information is crucial to researchers and public. To support more comprehensive annotation, integration, and analysis of COVID-19 vaccine infor-mation, we have developed Cov19VaxKB, a knowledge-focused COVID-19 vaccine database (http://www. violinet.org/cov19vaxkb/). Cov19VaxKB features comprehensive lists of COVID-19 vaccines, vaccine for-mulations, clinical trials, publications, news articles, and vaccine adverse event case reports. A web-based query interface enables comparison of product information and host responses among various vaccines. The knowledge base also includes a vaccine design tool for predicting vaccine targets and a statistical analysis tool that identifies enriched adverse events for FDA-authorized COVID-19 vaccines based on VAERS case report data. To support data exchange, Cov19VaxKB is synchronized with Vaccine Ontology and the Vaccine Investigation and Online Information Network (VIOLIN) database. The data integration and analytical features of Cov19VaxKB can facilitate vaccine research and development while also serving as a useful reference for the public. (c) 2022 University of Michigan.
