Power-law city-size distributions are a statistical regularity researched in many countries and urban systems. In this history of science treatise we reconsider Felix Auerbach’s paper published in 1913. We reviewed his analysis and found (i) that a constant absolute concentration, as introduced by him, is equivalent to a power-law distribution with exponent $$\approx 1$$ ≈ 1, (ii) that Auerbach describes this equivalence, and (iii) that Auerbach also pioneered the empirical analysis of city-size distributions across countries, regions, and time periods. We (...) further investigate his legacy as reflected in citations and find that important follow-up work, e.g. by Lotka (Elements of physical biology. Williams & Wilkins Company, Baltimore, 1925) and Zipf (Human behavior and the principle of least effort: an introduction to human ecology, Martino Publishing, Manfield Centre, CT (2012), 1949), does give proper reference to his discovery—but others do not. For example, only approximately 20% of city-related works citing Zipf (1949) also cite Auerbach (Petermanns Geogr Mitteilungen 59(74):74–76, 1913). To our best knowledge, Lotka (1925) was the first to describe the power-law rank-size rule as it is analyzed today. Saibante (Metron Rivista Internazionale di Statistica 7(2):53–99, 1928), building on Auerbach and Lotka, investigated the power-law rank-size rule across countries, regions, and time periods. Zipf’s achievement was to embed these findings in his monumental 1949 book. We suggest that the use of “Auerbach–Lotka–Zipf law” (or “ALZ-law”) is more appropriate than “Zipf’s law for cities”, which also avoids confusion with Zipf’s law for word frequency. We end the treatise with biographical notes on Auerbach. (shrink)

Inspiré de la pratique de l’auteure auprès de personnes en situation d’exil et de précarité rencontrées en centre d’hébergement pour demandeurs d’asile, cet article questionne la parentalité interne (Ciccone, 2012) dans l’économie psychique d’un homme confronté pendant son enfance aux mauvais traitements de son père et au départ définitif de sa mère, longtemps violentée. L’auteure s’intéresse à ses efforts pour se différencier des violences subies mais aussi à la reproduction inconsciente des rapports d’emprise et d’abandon, manifeste dans le lien transférentiel, (...) et à sa propre paternité dans un parcours d’exil et d’errance en quête d’objets parentaux. Le travail thérapeutique se focalise sur la restauration de ses capacités de contenance et de transformation dans une clinique du lien intersubjectif et intrapsychique. (shrink)
