- Den här artikeln utforskar olika implementeringar av och lärares erfarenheter från utmaningsdriven utbildning och liknande lärandemetoder inom ingenjörsutbildning och andra högre utbildningssammanhang. Genom en aktionsforskningsmetod kan centrala problem bland lärarna och likheter och skillnader mellan de studerade kurserna identifieras. Studien belyser potentialen i dessa inlärningsmetoder, som medel för att bryta och gå bortom de traditionella gränserna för högre utbildning, förbättra och korsbefrukta ingenjörsutbildning med andra discipliner och ge studenterna makt både som professionella och människor. Det indikerar också potentiella barriärer och inbyggda spänningar som är avgörande att hantera för framgångsrik implementering. Studien visar vidare på stora möjligheter till ömsesidigt lärande och samarbete mellan lärare från olika sammanhang och bakgrunder. Resultaten diskuteras i relation till forskning inom områden som hållbarhetsutbildning, transformativt lärande och framtidsstudier, och möjligheter till vidare forskning och utveckling beskrivs.

Transformation-Driving Education: Perspectives Emerging in a Dialogue between Teachers with Experiences from Challenge-Driven Education
- 2022

Konferensbidrag (refereegranskat)abstract
- This Research Full Paper explores different implementations of and teachers’ experiences from challenge-driven education and similar learning approaches in engineering education and other higher education contexts. Through an action research approach key concerns among the teachers and similarities and differences between the studied courses can be identified. The study highlights the potential in these learning approaches, as means for breaking and going beyond the traditional boundaries of higher education, enhancing and cross-fertilizing engineering education with other disciplines, and empowering students both as professionals and humans. It also indicates potential barriers and in-built tensions that are crucial to handle for successful implementation. The study further shows on great opportunities for mutual learning and collaboration between teachers from diverse contexts and backgrounds. The findings are discussed in relation to research within domains such as sustainability education, transformative learning, and futures studies, and opportunities for further research and development are outlined.

- Protein synthesis is believed to be involved in stabilizing synaptic plasticity. Effects lasting longer than about 2-3h are considered to require synthesis of new proteins, implying a functional separation between early (E) and late (L) components. However, the issue of constitutive vs. new protein synthesis is still unclear, especially in young animals. Here, we examined the effects of two protein synthesis inhibitors, anisomycin and emetine, on long-term-potentiation (LTP) in CA1 area of hippocampal slices from 12- to 20-day-old rats. Either drug was applied from -30 min to +30 min with respect to LTP induction, a time window previously reported to be critical. However, the LTP remained stable under the entire recording period of 4h (anisomycin), or 8h (emetine). Proper preparation of emetine solution was evidenced by the fact that, in separate experiments, prolonged treatment with emetine gradually blocked baseline responses. Although no corresponding effect was observed with anisomycin, the drug was judged to be potent by its ability to inhibit yeast growth. The ability of anisomycin to inhibit protein synthesis was further confirmed by radiolabeling experiments assessing the degree of leucine incorporation. Our data suggest that LTP up to at least 8h is not dependent on triggered protein synthesis but can be attained by utilizing proteins already available at induction time.

- Surging glaciers are glaciers that experience rapidly accelerated glacier flow over a comparatively short period of time. Though relatively rare worldwide, Alaska is home to the largest number of surge-type glaciers globally. However, their impact on the broader socioecological system in the state is both poorly understood and under-researched, which poses a challenge in developing appropriate sustainability decisions in Alaska. We investigated how the surge patterns of the Bering Glacier in Alaska have potentially devastating effects on the local ecological biodiversity of its watershed via a structured decision-making analysis of the different possible consequences. Specifically, this analysis was conducted to explore the various outcomes of a Bering Glacier surge particularly if humans have an increased presence near the glacier due to the area potentially becoming a state park. This work explored the benefits of applying a risk and decision analytical framework in a cryosphere context, to better understand the socioeconomic impact of glacier surges. This is a novel approach in which a decision analysis tool was used to better understand an environmental sustainability challenge, offering an innovative method to support the achievement of the United Nations Sustainability Development Goals in Alaska. We therefore emphasise the need for integrated biophysical and socioeconomic analyses when it comes to understanding glacier hazards. Our research highlights the importance of understanding and researching biophysical changes as well as using a structured decision-making process for complicated hazard planning scenarios, exemplified via glaciated regions in Alaska, in order to create adaptation strategies that are sustainable and encompass the range of possible outcomes.

- A new European Union regulatory framework for the telecom sector has been under a process of transposition to national laws by its member states that should have been completed by the end of 2020, notwithstanding some delays. A core purpose of the regulatory framework is to guarantee that most citizens will have access to very fast Internet connections, capable of 100 Mbps download link speed, regardless of where they live. According to this new framework, in areas where the market does not deliver, governments are to launch public tenders for the deployment, maintenance, and operations of network infrastructure as well as services, and public funds should be used to support the deployment of these broadband networks in less densely populated areas. Needless to say, public tenders of this nature are subject to different criteria when it comes to candidate evaluation. In this paper, we present a decision model for the selection of operators to deploy and maintain broadband networks in scarcely populated areas, taking into consideration infrastructure costs, the technical quality offered by the solutions, and the credibility of the candidates. We suggest an integrated multi-stakeholder multi-criteria approach and demonstrate how it can be used in this complex area and find that in the example provided, taking a relevant set of criteria into the analysis, optical fibre networks hold much higher chances to be used in these public tenders compared to networks based on the broadly favoured 5G technology.

A real options approach to decision making in broadband technology selection

Tidskriftsartikel (refereegranskat)abstract
- The European Union has recently launched an ambitious plan to mitigate drastically, by 2025, the number of households lacking access to a 100 Mbps broadband connection through the subsidisation of the deployment of network infrastructure in rural areas. Decision makers such as governments and regulatory authorities therefore have to choose, among a pool of alternatives, a technology capable of delivering the required throughput on a large scale, based on a trade-off between the infrastructure costs and the subscribers’ perceived utility for each alternative. Such a trade-off is not simple, since there is no straightforward manner to rank the subscribers’ perceived utility against the network infrastructure cost. In this article, we propose a methodology based on real options, which outputs the value of each technology using multi-attribute value theory as an input, alongside the project’s risk and its costs.
