The political instrumentalization of the history of Ukraine carried out by the Russian Federation in the framework of the information war against Ukraine is covered in this article. This instrumentalization is exercised through media communication employing historical and political myths and narratives to vindicate Russia's aggressive actions. The latest information and communication technologies used by the Kremlin in the information war against Ukraine have been identified in this paper. Such destructive efforts often derail Ukrainian-Polish relations, which are particularly sensitive to historical and political issues. The reasons for the drawbacks of the Ukrainian authorities in counteracting the information aggression on the part of the Russian Federation are distinguished, and the measures that would contribute to an effective response to such aggression are outlined.

Semantische Datenmodelle sind das Verbindungsglied zwischen der Sicht und den Erwartungen des Nutzers an die Daten und der physischen Realisation und Implementation der Datenbasis. Der vorliegende Beitrag stellt das 'Entity Relationship Model' als das zur Zeit bekannteste semantische Modell vor. Dieses Modell operiert mit den fünf Kategorien Gegenstand, Wert, Assoziation, Attribut und Bindung. Alle für einen gegebenen Nutzer interessierenden Erscheinungen eines Ausschnitts der realen Welt müssen auf diese Kategorien abgebildet werden. Die Vorgehensweise beim Design eines solchen Systems wird am Aufbau des geographisch-historischen Informationssystems GEOHIST demonstriert. (pmb)

The interdisciplinary field of historical geographic information systems (HGIS) took root and flourished at the Social Science History Association (SSHA) in the late 1990s and early 2000s. This essay first recounts the growth of HGIS at SSHA and beyond. It then considers challenges that GIS continues to pose for historians and other scholars, such as the unfamiliarity of its conceptual framework and the time and expense often involved in building HGIS databases. The bare-bones visual culture ofSocial Science Historymay inhibit submissions by HGIS scholars, whose work typically includes color maps. Yet the enduring methodological and interdisciplinary interests of SSHA members provide a strong basis for continuing involvement by historians who use GIS. The essay closes with new directions in HGIS scholarship, including study of empirical uncertainty, historical gazetteers, textual analysis linked to GIS mapping, and comparison of topology and topography.

AbstractThis study applied the theory of motivated information management (TMIM) to examine how married couples manage uncertainty about partners' family health history. Spouses reported (N = 626) on TMIM variables and information seeking/provision at Time 1 and on actual information seeking/provision behavior 3 weeks later. Findings largely supported paths proposed in the TMIM, but the model did not predict actual information management behaviors. As the first TMIM study to analyze dyadic, two‐wave data, results underscore the interdependent nature of information management processes in that seeker's efficacy assessments were associated with provider's direct information provision, and these effects were mediated by provider's perceptions of seeker efficacy assessments. Information seeker's perceptions did not play as significant a role in the process.
