    Of people, land and bonds : contributions to lordship and administration in North-East Scotland in the Later Middle Ages
    (2026) Rogge, Jörg; Berlandi, Matthias; Weil, Sebastian
    Via three exemplary chapters the authors present the results of the DFG-funded research project entitled ‚Man Rent or Land Rent? Significance and function of land transfer for the practice of lordship of kings, lay lords and ecclesiastics in north-east Scotland in the later Middle Ages‘. This volume tried to offer a modified perspective on the organisation of the political society in late Medieval Scotland, formed through the bottom-up view of regional lordship and its respective sources. Scottish history should not only be told from the perspective of crown, magnates and the sources produced by and for them but bottom-up: There are large enough quantities of mostly underused sources stemming from clerical institutions, nobility and the burghs, which can further enhance our knowledge of the political structure and the socio-economic composition of the kingdom.

    Utilizing information communication technologies (ICTs) during the process of disaffiliating from the ultra-Orthodox community
    (2025) David, Yossi; Shomron, Baruch
    The ultra-Orthodox community is characterized by high levels of commitment to community and religion and insulation from the outside world. Leaving such a community resembles the process of migration, in which the individual encounters new cultures, norms, and behaviors. This presents challenges with integration and disaffiliated community members do indeed often lack the tools, skills, and knowledge to successfully integrate into their new societies. Through qualitative in-depth interviews, we examine the role of information communication technologies (ICTs) and media in the processes of disaffiliation from ultra-Orthodox communities. Findings reveal the enablers and constraints these individuals experience in their journey and shed light on the importance of media and ICTs in individuals’ attempts to build new lives outside the ultra-Orthodox community. This study contributes to a better understanding of the role of media and ICTs in the lives of people undergoing major life changes, such as disaffiliation from the ultra-Orthodox community.

    Numerical modelling of diffusion-limited mineral growth for geospeedometry applications
    (2025) Stroh, Annalena; Aellig, Pascal S.; Moulas, Evangelos
    Diffusion and crystal growth are common processes in nature and can be observed in rocks that have experienced relatively high temperatures. Information about these processes is stored in the composition gradients of minerals. Diffusion can either occur within single crystals or across mineral interfaces. In the case of intercrystalline ion exchange, composition profiles across the interfaces are always discontinuous and may exhibit sharp compositional gradients. The compositional discontinuity and the associated gradients require an accurate treatment for the interface boundary condition. Here, we present a software package (MovingBoundaryMinerals.jl) that is openly available. In this package, we use an adaptive finite element method to describe the diffusion-couple equilibrium by taking into account the moving boundary separating the two phases. In addition, we utilize an adaptive grid approach to resolve the compositional gradients accurately at the interface region. This approach allows modelling a wide range of applications from mineral diffusion, simple ion exchange between diffusion couples, and diffusion-limited growth. The package has been tested versus variable available analytical solutions for diffusion and growth, and several benchmark cases are presented. Finally, our package can be used to model compositional gradients in growing/dissolving/diffusing crystals in the framework of diffusion chronometry and geospeedometry. This approach can provide thermal/time constraints in various geologic phenomena.
