ABSTRACT

PurposeSome communities in the USA are remarkably better at responding to civic challenges than others. These communities are more competent at marshaling their resources - material and human - in service of their own needs. The authors' purpose in this paper is to enhance their collective understanding of ideas related to community-driven change and to describe the development of a civic capacity index (CCI), a measure of a community's capacity to respond to civic challenges and disruptions like COVID-19.Design/methodology/approachThe authors used a concept mapping process (akin to grounded theory) to develop the CCI. Using this process, a panel of 34 scholars and practitioners of civic leadership and civic engagement worked together to create measurable descriptors of civic capacity.FindingsThe CCI measures dynamic processes related to collective leadership, inclusion of diverse voices, how institutions and coalitions address shared challenges and collaboration among community members. Sample data from several states show the CCI's scales to have high internal reliabilities and to correlate strongly with validation scales such as collective efficacy, social justice and community connectedness. Confirmatory factor analyses support a bifactor model of a general CCI factor and six CCI scales.Practical implicationsWith the help of the CCI, civic actors can take advantage of existing civic capacity, understand where it is lacking and build resilience for the future.Originality/valueTo date, most scholars have used qualitative research to determine the elements of civic capacity. The authors wanted to know what civic capacity looks like in sufficient detail to assess the extent to which it is present or not in a community. Other efforts to quantify or assess civic capacity or related ideas are less comprehensive or lack the specificity to provide guidance for building and mobilizing it in communities. This work enhances our understanding of leadership in the civic arena, a little understood aspect of leadership studies.

ABSTRACT

INTRODUCTION: The etiology of myocarditis often remains undetermined. A large variety of infectious agents, systemic diseases, drugs, and toxins can cause the disease. We report the case of a 19-year-old man who developed myocarditis three days after Pfizer-BioNTech COVID-19 booster vaccination. CASE REPORT: A 19-year-old man, presenting with troponin-positive acute chest pain, was referred to our department. He had received the Pfizer-BioNTech COVID-19 vaccine three days prior to his admission. The diagnosis of acute myocarditis was confirmed by cardiovascular magnetic resonance imaging. Patient hemodynamic status remained stable during hospitalization. The left ventricular ejection fraction was preserved during hospital stay and at one-month follow-up. We found no evidence for another infectious or autoimmune etiology. CONCLUSION: Although imputability of the vaccine cannot be formally established on the basis of this case report, the findings raise the possibility of an association between mRNA COVID-19 vaccination and acute myocarditis.

ABSTRACT

The COVID-19 pandemic has resulted in dramatic changes to the daily habits of billions of people. Users increasingly have to rely on home broadband Internet access for work, education, and other activities. These changes have resulted in corresponding changes to Internet traffic patterns. This paper aims to characterize the effects of these changes with respect to Internet service providers in the United States. We study three questions: (1) How did traffic demands change in the United States as a result of the COVID-19 pandemic?;(2) What effects have these changes had on Internet performance?;(3) How did service providers respond to these changes? We study these questions using data from a diverse collection of sources. Our analysis of interconnection data for two large ISPs in the United States shows a 30–60% increase in peak traffic rates in the first quarter of 2020. In particular, we observe traffic downstream peak volumes for a major ISP increase of 13–20% while upstream peaks increased by more than 30%. Further, we observe significant variation in performance across ISPs in conjunction with the traffic volume shifts, with evident latency increases after stay-at-home orders were issued, followed by a stabilization of traffic after April. Finally, we observe that in response to changes in usage, ISPs have aggressively augmented capacity at interconnects, at more than twice the rate of normal capacity augmentation. Similarly, video conferencing applications have increased their network footprint, more than doubling their advertised IP address space. © 2021, Springer Nature Switzerland AG.

ABSTRACT

This article summarizes the conclusion of a two-days interprofessional online workshop held under the auspices of the Brocher Foundation. The objectives were to review the impact of COVID on adolescent health and development and to generate some key responses to the situation. The pandemic has severely affected the mental health of a large proportion of adolescents and has significantly reduced access to health care. It has as well disturbed the school education of vulnerable youngsters and decreased social contacts with adults and peers. In the future, authorities should better consider the rights of young people and request their opinion and participation in decision making. Physicians should systematically explore their young patients' opinions and queries regarding the COVID and address problematic situations such as family conflicts, misuse of internet or risky behaviour.
