European airlines' strategic responses to the COVID-19 pandemic (January-May, 2020).

This paper analyzes airline reactions to the COVID-19 crisis in the spring months of 2020 along the typical crisis response strategies of retrenchment, persevering, innovating, and exit. Based on the content analysis of 148 news items filtered from a daily aviation industry newsletter published during the unfolding of the crisis in Europe (from January 6 to June 2), the paper specifies and differentiates European airlines' strategic responses, outlines key implications for the post-COVID-19 competitive landscape, and raises attention points for managers and policy makers.

Network of Networks: Preliminary Lessons from the Antwerp Port Authority on Crisis Management and Network Governance to Deal with the COVID-19 Pandemic.

In this article, the authors describe and illustrate what they call a "network of networks" perspective and map the development of a lead network for the Antwerp Port Authority that governed organizations and networks in the port community before and during the COVID-19 pandemic. They find that setting a collective focus and selective integration are crucial in the creation and reproduction of an effective system to adequately deal with a wicked problem like the COVID-19 pandemic. The findings on crisis management and network governance are used to engage practitioners and public policy planners to revisit the current design and governance of organizational networks within organizational fields that have been hit by the COVID-19 pandemic.

Minimally Invasive Distal Metatarsal Metaphyseal Osteotomy of the Lesser Toes: Learning Curve.

BACKGROUND: Minimally invasive surgery has a shorter surgical time, and in this study we focus on minimally invasive distal metatarsal metaphyseal osteotomy (DMMO). The operation seems to be less complex but requires a high learning curve. We report on our first patients to underline the need for extensive training and great awareness for the risks in the early learning stages. METHODS: We evaluated 27 patients (mean age = 60.9 years) with a mean follow-up time of 7.2 months. Indication was metatarsalgia, intractable plantar keratosis, and the (sub-)luxation of the metatarsophalangeal joint. Clinical results were evaluated with the 12-item Short Form (SF-12), Foot Function Index (FFI), Foot and Ankle Ability Measure (FAAM), and the American Orthopaedic Foot and Ankle Score (AOFAS). Radiographs and pedobarographic analysis were obtained. RESULTS: Scores ranged closely to standard value (AOFAS 88.07 points; FFI 93%; FAAM 36.4 points; SF-12 31.27 points). Pedobarography showed significant differences in several forefoot areas. We encountered nonunion/malunion and necrosis of the metatarsal head. CONCLUSIONS: The aim of this study was to demonstrate the need for intensive training before practicing DMMO. Results show that minimally invasive DMMO requires a high learning curve. Correct handling of the burr is associated with a lot of training. Wrong handling can lead to nonunion/malunion or necrosis. LEVELS OF EVIDENCE: Therapeutic, Level IV: Case series.
