Econometrics and archival data: Reflections for purchasing and supply management (PSM) research

Purchasing and supply management (PSM) has faced unprecedented disruption over the past two years due to COVID-19 pandemic, input shortages, extended supplier lead times, record international transportation costs, and commodity price increases. Studying such phenomena is often best completed using archival data, such as data from government agencies or international organizations. This manuscript emphasizes how leveraging archival data often necessitates an iterative research process whereby researchers must first familiarize themselves with the data to ensure their scientific hypotheses can be appropriately tested. We further provide recommendations regarding how researchers should formulate generalized linear models (GLMs) to test theoretical predictions. Our approach emphasizes mapping scientific hypotheses to statistical hypotheses, as opposed to centering on issues of omitted variable bias (OVB). An illustrative example is provided where Census Bureau trade data are compiled to test whether the insurance and freight costs for waterborne containerized imports from Asian nations that enter through West Coast ports have risen more than the same products imported through East Coast ports. The research suggests the need to reorient how GLMs are formulated to better ensure researchers structure them to appropriately test their theory, in contrast to the current zeitgeist that overly emphasizes OVB.

The Personal Experiences of Pastoral Leaders During the COVID-19 Quarantine

COVID-19 proved to be a unique crisis for churches and their pastoral leaders as they were forced to move their worship and work to an online format. This article reports on 33 pastoral leaders in 13 states who identified surprisingly positive experiences to go with the unsurprisingly negative reality of quarantine. It would appear that COVID-19, while brutal in its methods, naturally incubated reflection and positive growth in the lives of these pastoral leaders.

Multisystem inflammatory syndrome in children associated with novel coronavirus SARS-CoV-2: Presentations to a pediatric emergency department in Michigan.

The SARS-CoV-2 is a respiratory virus of the coronavirus family responsible for a global pandemic since December 2019. More than 35 million people have been affected with the novel coronavirus disease (COVID-19), with more than one million deaths worldwide. Michigan was one of the top three states in the United States that was severely affected by the SAR-CoV-2 pandemic with more than 7000 deaths in adults and greater than 145,000 confirmed infections. However, compared to adults, the majority of children until recently were either asymptomatic or had a mild illness with SARS-CoV-2. Recently, a rare but potentially serious presentation associated with SARS-CoV-2 called multisystem inflammatory syndrome in children (MIS-C) has been recently reported and the Centers for Disease Control (CDC) released a case definition for the same. We report the clinical and laboratory presentations and outcomes of 34 children with MIS-C who were evaluated within a 12 week period at a pediatric emergency department (PED) of single institution in Michigan. These cases presented approximately three weeks after the peak of adult SAR-CoV-2 related deaths occurred in the state. While many children presented with clinical characteristics similar to incomplete Kawasaki disease (KD), they also exhibited certain unique features which differentiated MIS-C from KD. The information presented below will aid clinicians with early recognition, evaluation and management of MIS-C in the emergency department.
