(American Geophysical Union, 2022)Space weather: the international journal of research and applicationsWe present a methodology that allows researchers to simulate in real time the spatiotemporal dynamics of the ground electric field (GEF) in a given 3-D conductivity model of the Earth based on continuously augmented data on the spatiotemporal evolution of the inducing source. The formalism relies on the factorization of the source by spatial modes (SM) and time series of respective expansion coefficients and exploits precomputed GEF kernels generated by corresponding SM. To validate the formalism, we invoke a high-resolution 3-D conductivity model of Fennoscandia and consider a realistic source built using the Spherical Elementary Current Systems (SECS) method as applied to magnetic field data from the International Monitor for Auroral Geomagnetic Effect network of observations. The factorization of the SECS-recovered source is then performed using the principal component analysis. Eventually, we show that the GEF computation at a given time instant on a 512 × 512 grid requires less than 0.025 s provided that GEF kernels due to pre-selected SM are computed in advance. Taking the 7–8 September 2017 geomagnetic storm as a space weather event, we show that real-time high-resolution 3-D modeling of the GEF is feasible. This opens a practical opportunity for GEF (and eventually geomagnetically induced currents) nowcasting and forecasting.

(2001)This is a study of all the reasons why it is impossible to allow the Miccosukee Tribe of Florida to use their own culturally determined mode of dispute resolution to settle a homicide case. However, it is simultaneously also a methodological experiment on the way anthropological approach can be used to study state law. Thus, despite the importance of answers to the question posed here, at least equal significance is placed on all the ancillary information acquired on the way to answers: what kind of difficulties such an approach entails, and what kind of methodological choices can be used to overcome them. In other words the attempt is to take rather orthodox, although modified, anthropological methods to a whole new setting, and to study both what kind of new insights could be gained from such an approach, and to examine what kind of contributions the method could offer to this new field. Further questions are also created on the relationship of state law to other modes of social control - should all of them be the subject of study, or should clear division be maintained between formal and casual modes dispute resolution? What should then be identified as social control, and who should be identified as its author? Overall the study derives from a variety of sources, including newspaper articles, communications from the attorneys of the parties involved and other online documents.

(2019)This article defends a formalist interpretation of Wittgenstein’s later thought on music by comparing it with Eduard Hanslick’s musical formalism. In doing so, it returns to a disagreement I have had with Bela Szabados who, in his book Wittgenstein as a Philosophical Tone-Poet, claims that the attribution of formalism obscures the role that music played in the development of Wittgenstein’s thought. The paper scrutinizes the four arguments Szabados presents to defend his claim, pertaining to alleged differences between Wittgenstein and Hanslick on their accounts of theory, beauty, rules, and the broader significance of music. I will argue that in each case the similarities between Wittgenstein’s and Hanslick’s respective views outshine possible differences. Ultimately, I will argue that instead of rendering music a marginal phenomenon suited for mere entertainment, formalism –as presented by Hanslick and Wittgenstein, whom I read as influenced by Kant’s aesthetics– underscores music’s ability to show fundamental features of reality and our relation to it. Music does this precisely as a sensuous yet structured medium that is irreducible to any conceptually determined domain.
