Presenting, (re)constructing and arranging medieval artefacts from non-religious and religious contexts : challenges in the digital age
Antje Roggenkamp, 2024, original scientific article

Abstract: The influence of digitalised images on individual and societal life has become considerable. The digital media revolution exercises a particular impact on the way we engage with works of art. In contrast to other educational institutions, museums structure the relationship to the past primarily through the arrangement of objects and artefacts, and they ensure that religious and non-religious cultural heritage is preserved. However, the emergence of digital technologies is changing the self-image of museums. Even though digital copies are playing an important role for presenting medieval artefacts, there are still hardly any criteria to determine their use in muse-ums. In this regard, the present study begins with a practice-orientated re-reading of Walter Benjamin’s classic essay “The Work of art in the age of its Technological Reproducibility”. Benjamin’s essay focuses on the aura of an original work of art, which changes when it is technologically reproduced. In a practice-orientated re--reading, Benjamin’s aura can be considered from different aspects: as practices of describing, seeing and comparing. From this perspective, a deeper re-reading takes these practices as a starting point for developing further criteria: modes of presen-ting, (re)constructing and arranging. as a result, the application of these practices and criteria opens up new perspectives not only for engaging with works of art and their technologically reproduced copies, but also for digital copies. Two case studies will be used to examine whether and to what extent the crite-ria gained by re-reading Benjamin’s essay are suitable for facilitating the accessibi-lity of artefacts through digital copies. The chosen artefacts date from the period to which Benjamin ascribes the largest dense aura – the Middle ages: the Bayeux Tapestry and the Halderner altar.
Keywords: practice-theoretical approach, (religious) work of art, original artefacts, Bayeux tapestry, Halderner altar, (religious) materiality, digital copy, mechanical produced copy

The precarious relationship between embodiment and digital religion
Tobias Friesen, 2024, original scientific article

Abstract: This article presents a critique of the prevalent notion that the digital realm is characterized by a condition of disembodiment and excarnation. In order to sub-stantiate its argument, this article initially presents an example of the discourse surrounding the disembodiment thesis, namely Richard Kearney’s considerations of touch in the digital age. In this context, the article uncovers a dominant discur-sive framing of harmonization vs. over-problematization. It then proceeds to exa-mine the work of Thomas Fuchs and his phenomenological critique of virtuality, which also emphasizes the aspect of disembodiment. Lucy Osler presents a coun-terargument to the thesis of disembodiment, simultaneously contributing to both phenomenological and embodiment research. Following Osler, this article argues that embodiment is inherently precarious and that the digital sphere requires a theory of multiple modes of embodiment rather than the creation of a dichotomy between embodiment and the digital. The article concludes with some theoretical considerations of digital religion and theological reflections on the possibility of an online Eucharist, a topic that was prevalent in Christian theology during the COVID-19 pandemic.

Materiality, religion and the digital : a theoretical exploration of material religion in immersive platforms
Victoria Dos Santos, Eduardo Rodrigues da Cruz, 2024, original scientific article

Abstract: This article proposes that the material dimension of religion can be articulated and experienced online. Considering that religion is an embodied phenomenon which relies on material elements, this paper will particularly focus on religious practices taking place in immersive virtual platforms in order to comprehend how the material dimension is manifested by users in their everyday life. Through a the-oretical analysis, we propose that 3D social virtual worlds efficiently enable users to experience key material aspects such as embodiment and space, due to their high levels of immersivity, interactivity, and agency, by embodying avatars in customi-zable spaces. Meyer’s theory of mediation, Hoover and Echchaibi’s Third Spaces of Digital Religion, and Campbell’s theory of Religious–Social Shaping of Digital Technology (RSST) allows us to center the discussion on how religions are practi-ced and experienced by individuals and communities through various mediation practices, and how digital media acquires more affective meanings when they are involved in religious pursuits.

Higher-order asynchronous effects
Danel Ahman, Matija Pretnar, 2024, original scientific article

Abstract: We explore asynchronous programming with algebraic effects. We complement their conventional synchronous treatment by showing how to naturally also accommodate asynchrony within them, namely, by decoupling the execution of operation calls into signalling that an operation's implementation needs to be executed, and interrupting a running computation with the operation's result, to which the computation can react by installing interrupt handlers. We formalise these ideas in a small core calculus and demonstrate its flexibility using examples ranging from a multi-party web application, to pre-emptive multi-threading, to (cancellable) remote function calls, to a parallel variant of runners of algebraic effects. In addition, the paper is accompanied by a formalisation of the calculus's type safety proofs in Agda, and a prototype implementation in OCaml.
Keywords: algebraic effects, asynchrony, concurrency, interrupt handling, signals, promises

When objects go wandering - lost and found objects from the Skušek collection
Helena Motoh, 2025, original scientific article

Abstract: This paper examines the phenomenon of “wandering objects” through the lens of the Skušek Collection, the largest collection of East Asian objects in Slovenia, which was brought to Ljubljana by Ivan Skušek Jr. and his Japanese wife, Tsuneko Kondō Kawase, in 1920. This collection, which traversed private ownership and eventual institutionali-sation, illustrates the dynamic mobility of artefacts. This study focuses on the movement of these objects both within and outside the family network, exploring how they were dispersed and sometimes reintegrated into the collection. By analysing specific cases, such as the three Japanese screens and other key objects, this paper identifies unique mobility patterns that differ from more common notions of dissociation and “orphaning” in the research of museum collections. The findings highlight the symbolic roles these “wander-ing objects” played in reinforcing social ties and cultural identity. This research contributes to a broader understanding of object mobility and provenance, offering a new conceptual framework for the research of private and institutional collections.

Establishing benchmark properties for 3D-printed concrete : a study of printability, strength, and durability
Alise Sapata, Maris Šinka, Genadijs Šahmenko, Lidija Korat Bensa, Lucija Hanžič, Katarina Šter, Sandris Rucevskis, Diana Bajare, Fred P. Bosselman, 2025, original scientific article

Abstract: This study investigates the fresh state and hardened state mechanical and durability properties of 3D-printed concrete. The mechanical tests focused on its anisotropic behavior in response to different load orientations. Compressive, flexural, and splitting tensile strengths were evaluated relative to the print layers orientation. Results showed that compressive strength varied significantly, achieving 85% of cast sample strength when the load was applied parallel to the print layers ([u] direction), 71% when the load was applied perpendicular to the print object’s side plane ([v] direction), while only reaching 59% when applied perpendicular to the top plane ([w] direction). Similar trends were observed for flexural strength, with average values reaching 75% of cast sample strength when the load was applied perpendicular to the print layers ([v.u] and [w.u] directions), but decreasing to 53% when the load was applied parallel to print layers ([u.w] direction), underscoring the weaknesses at interlayer interfaces. The splitting tensile strength remained relatively consistent across print orientations, reaching 90% of the cast sample strength. Durability assessment tests revealed that 3D-printed concrete exhibits reduced resistance to environmental factors, particularly at the layer interfaces where the cold joint was formed, which are prone to moisture penetration and crack formation. These findings contribute valuable insights into the mechanical and durability properties of 3D-printed concrete, emphasizing the importance of print orientation and interlayer bonding in its performance. This understanding helps guide the optimal use of 3D-printed elements in real-life applications by aligning load or exposure to environmental factors with the material’s strength and durability characteristics.

The different aspects of the housing quality of older adults : which criteria should be prioritized?
Richard Sendi, Maša Filipovič Hrast, Ajda Šeme, Boštjan Kefo Kerbler, 2024, original scientific article

Abstract: Various studies have identified that older adults’ assessment oftheir housing quality differs from that deemed as good quality housing by housing professionals. This has prompted the need to advance academic discourse beyond simply reporting highlevels of satisfaction in older adult’s housing surveys. This studyattempts to achieve this by using empirical data gatheredthrough a mixed quantitative and qualitative research approachconducted with older adults in Slovenia. While the quantitativesurvey revealed generally high levels of satisfaction, the qualitative face-to-face interviews revealed numerous deficiencies,irrespective of whether older adults tended to express satisfaction with their dwellings. Therefore, our findings suggest thatattributes such as ownership, period of residence, and neighborhood relations are far more important in determining housing satisfaction. Thus, we conclude that policies and programsfor modifying housing for older adults must be based ona deeper understanding of their specific needs. During thepolicy formulation process and the implementation of specifichousing improvement programs, emphasis should be placed onthe social-historical aspects related to the lifestyle of each specific older adult.

Ljubljana - European green capital 2016 : from strategic spatial planning to governance
Kaliopa Dimitrovska Andrews, Matej Nikšič, Luka Mladenovič, Boštjan Cotič, Barbara Mušič, Boštjan Kefo Kerbler, 2024, original scientific article

Abstract: Ljubljana was the first post-socialist city awarded with the title European Green Capital. The title awarded by the European Commission is given to a city that is achieving high environmental standards, is setting ambitious goals for further environmental improvement and sustainable development, and can act as a role model to inspire other cities and promote best practices to all other European cities. The article is based on a hypothesis that at the moment when Ljubljana applied for (and was awarded) the European Green Capital title, it had strong strategic spatial planning and successful territorial governance, as well as the interweaving of both. To prove the hypothesis, the timetable and characteristics of the strategic spatial planning and territorial governance in Ljubljana are presented in this article and critically evaluated. Critical evaluation and analyses are also assessed using a qualitative research method, i.e., semi-structured in-depth interviews among experts from four professional fields including spatial planning, urbanism, architecture, and management. The results confirmed the hypothesis: Ljubljana’s sustainability-oriented strategic spatial plan prepared by a variety of stakeholders, experts, and citizens, as well as the effective governance system established by the mayor, a manager by profession, were two factors that coincided at a crucial moment. This was recognized by the European Commission and Ljubljana was awarded a prestigious title. Ljubljana can therefore serve as an excellent sustainable example for other post-socialist cities in terms of strategic spatial planning and governance.

Quaternionic Cartan coverings and applications
Jasna Prezelj, Fabio Vlacci, 2025, original scientific article

Abstract: We present the topological foundations for solvability of multiplicative Cousin problems formulated on an axially symmetric domain ΩH. In particular, we provide a geometric construction of quaternionic Cartan coverings, which are generalizations of (complex) Cartan coverings as presented in Section 4 of Forstnerič and Prezelj (Math. Ann. 322(4), 633-666 (2002)). Because of the requirements of symmetry inherent to the domains of definition of quaternionic regular functions, the existence of quaternionic Cartan coverings of Ω is not a consequence of the existence of complex Cartan coverings; for the latter, there are no requirements for the symmetries with respect to the real axis. Due to the real axis’s special role, also the covering restricted to ΩR must have additional properties. All these required properties were achieved by starting from a particular symmetric tiling of the symmetric set Ω(R+iR). Finally, we apply these results to prove the vanishing of ’antisymmetric’ cohomology groups of planar symmetric domains for n2.
