T1 - Coronitalization BT - Effekte der Corona-Pandemie auf die Digitalisierung der Verwaltung T2 - Handbuch Digitalisierung der Verwaltung N2 - Nach mehreren Jahren weltweiter Pandemie ist deutlich geworden, dass Corona Verwaltungshandeln in erheblichem Maße beeinflusst und bestimmt hat. Dieser Beitrag fasst die Forschung und empirischen Erkenntnisse zur Verwaltungsdigitalisierung während der Corona-Pandemie in Deutschland thematisch zusammen. Dabei wird untersucht, inwiefern die Kontaktbeschränkungen und Infektionsschutzmaßnahmen die Digitalisierungsvorhaben in der öffentlichen Verwaltung beeinflusst und vorangebracht haben. Insgesamt ist von einem Schub für die Digitalisierung durch die Corona-Pandemie auszugehen. Eine solche Coronitalization äußerte sich vor allem in verstärkten Investitionen in IKT und E-Services und der vermehrten Abkehr von analogen Prozessen sowie dem Einsatz flexibler Arbeitsmodelle, wie dem Homeoffice, unter Zuhilfenahme digitaler Infrastruktur.

Just about every company has been affected in one way or another. This first empirical study on the effects of the COVID-19 crisis on family firms allows initial conclusions to be drawn about family firm crisis management. Design/methodology/approach Exploratory qualitative research design based on 27 semi-structured interviews with key informants of family firms of all sizes in five Western European countries that are in different stages of the crisis. Findings The COVID-19 crisis represents a new type and quality of challenge for companies. These companies are applying measures that can be assigned to three different strategies to adapt to the crisis in the short term and emerge from it stronger in the long run. Our findings show how companies in all industries and of all sizes adapt their business models to changing environmental conditions within a short period of time. Finally, the findings also show that the crisis is bringing about a significant yet unintended cultural change. On the one hand, a stronger solidarity and cohesion within the company was observed, while on the other hand, the crisis has led to a tentative digitalization. Originality/value To the knowledge of the authors, this is the first empirical study in the management realm on the impacts of COVID-19 on (family) firms. It provides cross-national evidence of family firms' current reactions to the crisis.

Mit der Pandemie änderte sich die Situation unerwartet und womöglich auch nachhaltig. Vor dem Hintergrund unterschiedlicher Erfahrungen ist die Frage nicht mehr ob, sondern wie zukünftig in der Verwaltung mobil, flexibel und dezentral sowie in virtuellen Teams gearbeitet werden kann und soll. Dieser Beitrag untersucht diese Konzepte genauer, veranschaulicht deren praktische Anwendung und erörtert entsprechende Perspektiven für das zukünftige Arbeiten im öffentlichen Dienst.

A1 - Chintzoglou, Georgios T1 - Triggering an Eruptive Flare by Emerging Flux in a Solar Active-Region Complex JF - Solar physics : a journal for solar and solar-stellar research and the study of solar terrestrial physics N2 - A flare and fast coronal mass ejection originated between solar active regions NOAA 11514 and 11515 on 2012 July 1 (SOL2012-07-01) in response to flux emergence in front of the leading sunspot of the trailing region 11515. Analyzing the evolution of the photospheric magnetic flux and the coronal structure, we find that the flux emergence triggered the eruption by interaction with overlying flux in a non-standard way. The new flux neither had the opposite orientation nor a location near the polarity inversion line, which are favorable for strong reconnection with the arcade flux under which it emerged. Moreover, its flux content remained significantly smaller than that of the arcade (). However, a loop system rooted in the trailing active region ran in part under the arcade between the active regions, passing over the site of flux emergence. The reconnection with the emerging flux, leading to a series of jet emissions into the loop system, caused a strong but confined rise of the loop system. This lifted the arcade between the two active regions, weakening its downward tension force and thus destabilizing the considerably sheared flux under the arcade. The complex event was also associated with supporting precursor activity in an enhanced network near the active regions, acting on the large-scale overlying flux, and with two simultaneous confined flares within the active regions.

A tight linkage through the nuclear envelope connects the cytosolic centrosome with the clustered centromeres within the nuclear matrix. At G2/M the corona dissociates, and the core structure duplicates, yielding two spindle poles. CP148 is a novel coiled coil protein of the centrosomal corona. GFP-CP148 exhibited cell cycle-dependent presence and absence at the centrosome, which correlates with dissociation of the corona in prophase and its reformation in late telophase. During telophase, GFP-CP148 formed cytosolic foci, which coalesced and joined the centrosome. This explains the hypertrophic appearance of the corona upon strong overexpression of GFP-CP148. Depletion of CP148 by RNAi caused virtual loss of the corona and disorganization of interphase microtubules. Surprisingly, formation of the mitotic spindle and astral microtubules was unaffected. Thus, microtubule nucleation complexes associate with centrosomal core components through different means during interphase and mitosis. Furthermore, CP148 RNAi caused dispersal of centromeres and altered Sun1 distribution at the nuclear envelope, suggesting a role of CP148 in the linkage between centrosomes and centromeres. Taken together, CP148 is an essential factor for the formation of the centrosomal corona, which in turn is required for centrosome/centromere linkage.

At the G2/M transition, the corona dissociates and the core structure duplicates, yielding two spindle pole bodies. Finally, in telophase, the spindle poles mature into two new, complete centrosomes. CP55 was identified in a centrosomal proteome analysis. It is a component of the centrosomal core structure, and persists at the centrosome throughout the entire cell cycle. FRAP experiments revealed that during interphase the majority of centrosomal GFP-CP55 is immobile, which indicates a structural task of CP55 at the centrosome. The CP55null mutant is characterized by increased ploidy, a less structured, slightly enlarged corona, and by supernumerary, cytosolic MTOCs, containing only corona proteins and lacking a core structure. Live cell imaging showed that supernumerary MTOCs arise in telophase. Lack of CP55 also caused premature recruitment of the corona organizer CP148 to mitotic spindle poles, already in metaphase instead of telophase. Forces transmitted through astral microtubules may expel prematurely acquired or loosely attached corona fragments into the cytosol, where they act as independent MTOCs. CP55null cells were also impaired in growth, most probably due to difficulties in centrosome splitting during prophase. Furthermore, although they were still capable of phagocytosis, they appeared unable to utilize phagocytosed nutrients. This inability may be attributed to their partially disorganized Golgi apparatus.
