Employee perspectives on value realization from data within data-driven business models
Autor: Matthias Förster, Bastian Bansemir, Angela Roth
Publikováno v: Electronic Markets. 32:767-806
Firms are innovating data-driven business models (DDBMs) to realize value from data. Yet, making DDBMs work is challenging, and DDBMs often fall short of expected value realization. One reason for this shortfall is that firms do not know how employee

Light Ion Dynamics in the Topside Ionosphere and Plasmasphere during Geomagnetic Storms
Autor: Ivan Pakhotin, Johnathan Burchill, Matthias Förster, Levan Lomidze
Storm-time topside ionosphere plasma composition, especially the light ion fraction, is an important parameter which controls magnetosphere-ionosphere coupling, plays a part in the growth of local instabilities, and provides information about the rin

Solar flux influence on the in-situ plasma density at topside ionosphere measured by Swarm satellites
Autor: Chao Xiong, Haicheng Jiang, Rui Yan, Hermann Lühr, Claudia Stolle, Fan Yin, Artem Smirnov, Mirko Piersanti, Yiwen Liu, Xin Wan, Piero Diego, Zeren Zhima, Xuhui Shen, Matthias Förster, Stephan Buchert, Dieter Bilitza
Publikováno v: Journal of Geophysical Research: Space Physics
In this study, we perform the first comprehensive comparison of ion density (Ni) in the topside ionosphere measured by the Langmuir probe (LP) and faceplate (FP) of the thermal ion imager on board Swarm satellites. Our results show a systematic diffe

Journal of Geophysical Research (JGR): Space Physics
When the geomagnetic field is weak, the small mirror force allows precipitating charged particles to deposit energy in the ionosphere. This leads to an increase in ionospheric outflow from the Earth's polar cap region, but such an effect has not been

International audience; The geomagnetic storm occurred on 25-26 August 2018 as a surprise to forecasters. The arrival of a weak coronal mass ejection did not show a sudden impulse in the magnetic data, however, when the IMF Bz turned southward, it in

Hall current variations in different time sectors during six magnetic storms from the summer seasons in 2003 and 2005 (Ritter, 2018) are examined, namely three storms in the day–night meridional sector and three storms in the dawn–dusk sector. Th
