The inside-out view on neutron-star magnetospheres
No full textWe construct hydromagnetic neutron star equilibria which allow for a non-zero electric current distribution in the exterior. The novelty of our models is that the neutron star's interior field is in equilibrium with its magnetosphere, thus bridging the gap between previous work in this area, which either solves for the interior assuming a vacuum exterior or solves for the magnetosphere without modelling the star itself. We consider only non-rotating stars in this work, so our solutions are most immediately applicable to slowly rotating systems such as magnetars. Nonetheless, we demonstrate that magnetospheres qualitatively resembling those expected for both magnetars and pulsars are possible within our framework. The ‘inside-out’ approach taken in this paper should be more generally applicable to rotating neutron stars, where the interior and exterior regions are again not independent but evolve together

Sound by Artists
No full textEditors Lexier and Lander present the anthology of the art of sound as an attempt to identify sound as an art practice and to highlight the non-visual aspects of perception. Includes 37 texts and a list of selected recorded works by the artists, biographical notes on the 35 contributors and an extensive bibliography (14 p.)
Nanosyntax: the basics
No full textThis chapter offers a thorough introduction to nanosyntactic theory, a development of the cartographic program in generative grammar. It discusses the foundations on which nanosyntax was conceived, such as the “one feature–one head” maxim and the universal functional sequence (fseq). It also provides a brief comparison of theoretical and terminological issues in nanosyntax vs. the competing framework of Distributed Morphology. It is seen that the syntactic component according to nanosyntax unifies aspects of (what are traditionally called) syntax, morphology, and formal semantics. This is reflected in the tools used to probe linguistic structure in the nanosyntactic approach, such as morphological decomposition, syncretism, and containment. The chapter also discusses the technical details of the syntax–lexicon relation, detailing the matching or spellout process and Starke’s view of spellout-driven movement. This chapter is meant to provide readers with the necessary background to understand and navigate the rest of the chapters in this volume
Refeudalization and the Crisis of Civilization. Political essays by Olaf Kaltmeier and Edgardo Lander
No full textKaltmeier O, Lander E. Refeudalization and the Crisis of Civilization. Political essays by Olaf Kaltmeier and Edgardo Lander. 1st ed. New York: Routledge; 2023.Discussing the civilizatory crisis and processes of refeudalization this volume brings into dialogue two of the most creative approaches, in Olaf Kaltmeier and Edgardo Lander, to rethink capitalism in the 21st century.
In Part 1, Olaf Kaltmeier, takes issue with the state of social inequality in the region, highlighting the concentration of wealth within the upper 1% of society in Latin America. Comparing the current economic situation with the ancient regime, the discussion centers around the new phenomena like billionaires as president, increased luxury consumption, an emerging culture of distinction, and the intensification of land and spatial segregation. In Part 2, Lander urgently assesses the current state and political legacy of the "Pink Tide" governments in his essay "Crisis of Civilization." Reviewing the past two decades of the new millennium, Lander critiques the failure of these governments to provide alternatives to extractivism and economic dependencies. Finally, Hans-Jürgen Burchardt connects the arguments through interviews where both authors sum their efforts to open the issues to future dialogue.
Refeudalization in Latin America provides an accessible and thought-provoking political diagnosis from the Global South which departs from the oft idiosyncratic and cyclical debates of the Global North to offer new vocabulary for social change. It will interest scholars and students of global studies, sociology, and political science
Magnetic fields in axisymmetric neutron stars
No full textWe derive general equations for axisymmetric Newtonian magnetohydrodynamics and use these as the basis of a code for calculating equilibrium configurations of rotating magnetized neutron stars in a stationary state. We investigate the field configurations that result from our formalism, which include purely poloidal, purely toroidal and mixed fields. For the mixed-field formalism, the toroidal component appears to be bounded at less than 7 per cent. We calculate distortions induced both by magnetic fields and by rotation. From our non-linear work, we are able to look at the realm of validity of perturbative work: we find for our results that perturbative-regime formulae for magnetic distortions agree to within 10 per cent of the non-linear results if the ellipticity is less than 0.15 or the average field strength is less than 10^17 G. We also consider how magnetized equilibrium structures vary for different polytropic indices
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
