WHAT ARE THE KEY FACTORS INFLUENCING HOUSEHOLD FORMATION AND CO-RESIDENCE PATTERNS? LEARNING FROM SOUTHEASTERN EUROPE by Siegfried Gruber, Daniel-Armin Đumić

“…This study presents updated maps that offer a more nuanced view of household structures in the region. The maps, based on individual-level data, reveal significant variation in marriage patterns, household formation, and co-residence across SEE, challenging earlier binary classifications of European household systems and highlighting the diversity within and beyond the Hajnal line. …”

Calcium effect on the Nernst coefficient in double-substituted Y1-xCaxBa2Cu2.8Zn0.2Oy by Чжан Суньпэн, Виталий Эдуардович Гасумянц

“…From this analysis, we determine the charge carrier mobility across all studied samples and then analyze its variation with increasing calcium content. It is shown that all experimental and calculated results can be explained if we take into account that both calcium and zinc directly affect the structure of the band responsible for the conduction process in the YBa2Cu3Oy system. …”
