While institutional frameworks are the dominant approach to analysing the geography of finance, this article focuses on how individual policymakers influence the characteristics of financial institutions and set, or even alter, financial centre development. The historical narratives from Central and Eastern Europe (CEE) that this article presents reveal post-socialist reformers' contrasting philosophies and approaches, despite their shared goals of market liberalisation and European integration. These reforms (or lack thereof) differentiated the securities markets in Warsaw, Prague, and Budapest, especially with respect to financial intermediary mechanisms. Although the legacies of such reforms continue to shape an uneven landscape of financial centres in CEE, this article proposes reformer-centred narratives as an alternative to deterministic institutional thinking. The article argues that historical narratives that foreground the actions and ideas of key policymakers need to be included in the observation framework of financial centre development, in a similar way to how scholars analyse foreign policy by focusing on the heads of governments and ministers.

How successful, and by what measure, has the accession of the 10 Member States in 2004 been? Reviewing European Union Accession addresses a wide range of issues, deliberately without any thematic constraints, in order to explore EU enlargement from a variety of perspectives, both scientific and geographical, internal and external. In contrast to the major works in this field, we highlight the interrelated, and often unexpected, nature of the integration process - hence the subtitle, unexpected results, spillover effects and externalities.

This special issue embeds the discourse on EU-Russia relations in International Society (IS) theory in order to create a level-playing field that has thus far eluded scholarly debates.

To know the properties of a particle or a wave, one should measure how its energy changes with its momentum. The relation between them is called the dispersion relation, which encodes essential information of the kinetics. In a magnet, the wave motion of atomic spins serves as an elementary excitation, called a spin wave, and behaves like a fictitious particle. Although the dispersion relation of spin waves governs many of the magnetic properties, observation of their entire dispersion is one of the challenges today. Spin waves whose dispersion is dominated by magnetostatic interaction are called pure-magnetostatic waves, which are still missing despite of their practical importance. Here, we report observation of the band dispersion relation of pure-magnetostatic waves by developing a table-top all-optical spectroscopy named spin-wave tomography. The result unmasks characteristics of pure-magnetostatic waves. We also demonstrate time-resolved measurements, which reveal coherent energy transfer between spin waves and lattice vibrations. Observation of the entire dispersion relation for spin waves remains a challenge which prevents the full understanding of many intriguing magnetic properties. Here, the authors develop a table-top all-optical approach to map out the dispersion curve of pure-magnetostatic waves in magnetic films.

The Cosmic Gems arc is among the brightest and highly magnified galaxies observed at redshift z  ≈ 10.2 (ref.  1 ). However, it is an intrinsically ultraviolet faint galaxy, in the range of those now thought to drive the reionization of the Universe 2 – 4 . Hitherto the smallest features resolved in a galaxy at a comparable redshift are between a few hundreds and a few tens of parsecs (pc) 5 , 6 . Here we report JWST observations of the Cosmic Gems. The light of the galaxy is resolved into five star clusters located in a region smaller than 70 pc. They exhibit minimal dust attenuation and low metallicity, ages younger than 50 Myr and intrinsic masses of about 10 6 M ⊙ . Their lensing-corrected sizes are approximately 1 pc, resulting in stellar surface densities near 10 5 M ⊙  pc −2 , three orders of magnitude higher than typical young star clusters in the local Universe 7 . Despite the uncertainties inherent to the lensing model, they are consistent with being gravitationally bound stellar systems, that is, proto-globular clusters. We conclude that star cluster formation and feedback likely contributed to shaping the properties of galaxies during the epoch of reionization. JWST observations of the Cosmic Gems arc resolve the light of an infant galaxy into five gravitationally bound star clusters located in a region smaller than 70 pc.
