1. Uncertainty modeling and stability assessment of minimum spanning trees in network designAhmad Hosseini, 2024, original scientific article Abstract: The Minimum Spanning Tree (MST) problem in networks focuses on finding efficient routes, with applications in transportation, logistics, telecommunications, and more. However, catastrophes can make these networks uncertain, requiring robust computational models for decision-making. This paper introduces an uncertainty theory-based model to analyze the stability of MSTs in uncertain networks. By incorporating reliability and risk variables, we assess the robustness of uncertain MSTs (UMSTs) and address the challenge of computing link tolerances, which define the range within which network links can vary without compromising MST optimality. This study proposes computational formulations to systematically calculate these tolerances, offering a more efficient alternative to traditional re-optimization methods.

2. The thread : master's thesisAnastasija Kojić, 2024, master's thesis Abstract: This thesis explores combination and intersection of activism and art through creative project that addresses issues of gender-based violence, precisely verbal abuse. The project was done in several phases, beginning with photography. Selection and photographing model, followed up by participating in the exhibition where women and girls wrote answers to main question on printed photographs. To gain a broader perspective, three focus groups with participants of different ages were held, additionally more insights were obtained by online conversations with selected participants. Inspired by the work of Chiharu Shiota, a red thread is used in the embroidery of photographic canvases, symbolizing resilience and reclaiming identity. Final installation was displayed in a way to encourage visitors to interact with embroidered canvass. This thesis advocates the idea that art can serve as a powerful vehicle for social commentary and healing, creating a platform for voices and encouraging dialogue on key social issues.

3. Promoting the use of open educational resources to improve teaching and learning of science subjects in secondary schools in Tanzania : master's thesisLucian Vumilia Ngeze, 2024, master's thesis Abstract: A number of challenges have hindered the integration of Open Educational Resources (OERs) in schools from developing countries. The rate of adoption of OERs in teaching and learning in schools in Tanzania is low. This research focused on capacity of secondary school science teachers on creating and adapting open educational resources to improve the teaching and learning of science subjects. The research used a Design-based Research methodology to achieve research objectives.
Results show that challenges such as lack of ICT devices, poor Internet connection, network accessibility issues, unstable power supply and large class sizes hindered the integration of OER in the teaching of science subjects. As teachers created OERs, they stated factors such as levels of the learners, developing engaging content, simple and self-explanatory content, alignment with learning objectives and relevancy of OER as initial considerations they considered when creating OERs. It was important to investigate the change in teachers’ attitude towards the use of OER in teaching science subjects OER creation ability, OER in teaching, teaching improvements, increased teaching resources, and application of skills.
It was concluded that regular teacher professional development programmes must be set to support school teachers in using OERs to improve teaching and learning and in creating OER for teaching. Engaging with relevant government bodies is encouraged to ensure that more teachers are involved in such developed online courses.

4. Taming the forest : embracing the complexity of art-sci research through microhistory, bioeconomics and intermedia artNikita Peresin Meden, Kristina Pranjić, Peter Purg, 2024, original scientific article Abstract: An ongoing collaborative project between art and science, Taming the Forest (2022) was implemented by a team of students, artists and researchers charting an interdisciplinary project among bioeconomics, environmental history, policy and artistic practice. In this article, the project acts as a case study for researching the conflicting narratives of history and economics about biodiversity in general, and specifically about forests. It shows how different blends of methodologies in artistic-cum-scientific research can become relevant for both realms, opening new creative pathways and pedagogical registers while repeatedly returning to a specific forest’s microhistory. Moreover, the article stresses the need for a new sensibility and complex knowledge, moving beyond an objective study and becoming attentive to different dimensions of research and its outputs that emerge through the introduction of artistic thinking and methodologies. This kind of transdisciplinary approach becomes necessary in order to tackle the manifold large-scale problems such as the climate and biodiversity crises, which call for both acting decisively and transforming radically, above all with regard to how humans perceive, relate to and manage nature.
Keywords: biodiversity, climate crisis, environmental history, forest management, Karst, transdisciplinary, artistic thinking, artistic research

6. Dancing sympathy beyond human failure : artistic research as cosmopolitical defuturingPeter Purg, 2023, original scientific article Abstract: abstract
The article explores the concepts, tools and methods that may be taken on board by artistic researchers when venturing into uncertain futures. The approaching hay-day of Artistic Research calls for a repositioning of this academic and cultural avantgarde that is assuming real power and must thus take clear opposition against dominant politics and corporate capitalism keeping the human and non-human kinds in perpetual crisis. Next to Science and Technology, Art has finally reached a status of an equivalued cornerstone, and within this level playing field a new research-based approach is needed where power relationships, decision-making mechanisms, dominant narratives or prevalent aesthetics are boldly investigated and critically questioned, (re)instituting the importance of artistic disruption and establishing art-thinking as the key to not only question but also design pathways to meaningful change. Deeply intertwined research methodologies ranging from social to natural sciences, from humanities via (critically reflected) technologies to the (technologically emancipated) arts, should be left to safely mingle and mutually inspire. Rather than colonizing it with yet another false supremacy, we should be learning from the Global South, where collective dancing, storytelling or performing still presents a norm of how to generate new knowledge or reach consensus. Artistic Research can contribute to crafting better worlds even once AI entities get accepted as fellow researchers (if not dancers), their agency reflected in an attitude of radical sympathy (re)instituting care, justice and solidarity by ways of sound research activism.
