Dynamic Shear Rheometer for rheological investigation of bitumen in road applications : The impact of measurement technique

The rheological properties of bituminous binders tested with a dynamic shear rheometer (DSR) as a function of loading time and temperature can more accurately represent real road situations with rising traffic loads and densities combined with climatic change. This method is more effective than traditional methods such as measuring the softening point and penetration. Complex shear modulus and pha

Making Sense without Meaning : Christopher Alexander and the Automation of Design

In his contribution to the infuential “Architecture and the Computer”conference in 1964, Christopher Alexander summarised the reorganisation of intellectual labour that, beginning in the 19th century,became fnally concretised in the technologies of the computer. Inhis opinion, computers should be regarded as nothing else than hugearmies of clerks, stupid and without initiative, but able to follow

Roadmap for AI Policy Research

This roadmap, developed through collaborative discussions at the recent AI PolicyResearch Summit, reflects a shared vision for advancing research on responsibleAI policy and governance. It emphasizes the critical role of policy research inensuring that AI development is guided by robust evidence, ethicalconsiderations, and a commitment to sustainability and inclusivity. By prioritizingtransparency

Stumpan, kan du sätta på lite kaffe och hämta chefen? - En kvalitativ studie om kvinnliga ledares upplevelser av inkludering på en mansdominerad arbetsplats

Forskningsfråga: Hur uppfattar kvinnor i ledarskapspositioner sin inkludering på en mansdominerad arbetsplats?; Hur förhåller sig kvinnorna till sin inkludering? Syfte: Studiens syfte är att nyansera kvinnliga chefers upplevda inkludering på mansdominerade arbetsplatser. Metod: För att uppnå uppsatsens syfte har en kvalitativ studie genomförts med en abduktiv ansats. Empirin består av 15 stycken s

Ledarskap som följarskap?

Titel: Ledarskap som följarskap - En kvalitativ studie av hur organisationskulturen formar ledarskapet inom IKEA Seminariedatum: 17 januari 2025 Kurs: FEKH49 - Examensarbete i organisation på kandidatnivå, 15 hp. Författare: Perya Khezri, Maria Nguyen, Cathina Cronquist Wigvall Handledare: Stefan Sveningsson Nyckelord: Ledarskap, organisationskultur, följarskap, social identifiering, kulturell un

Decision-making under uncertainty - The role of Descriptive, Predictive and Prescriptive Analytics

This study examines how descriptive, predictive, and prescriptive analytics are applied in decision-making during stable operations and disruptive events, focusing on the Swedish food retail sector during the Covid-19 pandemic. Using a qualitative case study approach with semi-structured interviews and pattern-matching analysis, the research reveals key differences in analytics usage. During stabl

Ideology and Self-censorship in Swedish University Students: A Survey Finding Support for Self-censorship Relating to Ideology

Populationen av västerländska akademiker och studenter visar tecken på ideologisk bias i termer av sin sammansättning och villighet att självcensurera. Denna studie undersökte en svensk population av studenter (N = 89), huvudsakligen från samhällsvetenskapliga områden, i termer av ideologi (Moral Foundations; MFQ-20 och Social Dominance Orientation; S-SDO). Studien undersökte också relationen mellThe population of western scholars and students shows signs of ideological bias in terms of its composition and willingness to self-censor. This study surveyed a Swedish student population (N =89) of predominantly social scientists on ideology (Moral Foundations; MFQ-20 and Social Dominance Orientation; S-SDO). The study also explored the relation between self-censorship (SC), age, gender and univ

Critical thinking in the age of big data and AI

This study examines the relationship between critical thinking and the use of Big Data Analytics (BDA) in decision-making among white-collar professionals. It focuses on three key areas: the influence of BDA reliance on critical thinking, the connection between professional experience and cognitive reasoning, and the demands of strategic decision-making compared to tactical and operational roles.

Assessing the Effect of Specimen Preparation Methods on DSR Test Results of Bitumen Using Factorial Design Analysis

A two-level three-factor factorial design experiment was conducted to study the influences of three critical specimen preparation parameters on the measurement results of bitumen by a dynamic shear rheometer (DSR). The investigated factors were (1) the pre-heating temperature (HT) for manufacturing the specimen, (2) the bonding temperature (BT) onto the rheometer, and (3) the trimming (Trim) opera

The Impact of Switch Faults on Train Delays : A Case Study of the Swedish Railway Network

Switches and crossings are prone to failure thus making them drivers of unreliability in the operation of many railway systems. Unreliability is directly linked to punctuality which continues to limit, among other factors, the uptake of railways as a sustainable mode of transport. To fix this issue, there is a need for a better understanding of the contribution of railway sub-systems to train dela

Real-time High-Speed Train Delay Prediction using Seemingly Unrelated Regression Models

Understanding the impact of various factors on train arrival delays is a prerequisite for effective railway traffic operating control and management. Existing studies model the train delay prediction problems using a single, generic equation, restricting their capability in accounting for heterogeneous impacts of spatiotemporal factors on arrival delays as the train travels along its route. The pa

Sámi Resurgence through Heritage Work : Exploring Sámi Cosmology in Negotiation with Lutheran Christianity

With the aim to reach deeper insights into dynamics of resilience and resurgence in Sámi systems of knowledge, this article explores how Sámi worldviews and knowledges are enacted and passed on despite violent efforts of erasure by colonial state actors and settler colonialists. I analyze a variety of sources—interviews, a podcast, a documentary and a magazine—to highlight Sámi resilience and resu

Conferencing in times of climate crisis and Covid-19 : feminist and queer reflections on the digital shift in academic work

This article employs a holistic understanding of environmental, social, and economic sustainability to explore the interaction between neoliberalism, climate crisis, digitalization, and academic work with a focus on its everyday aspects. Drawing our experience of organizing an online conference during the Covid-19 pandemic and our dialogue with conference participants, we first problematize the pr

Schwarz Waveform Relaxation for a Single Column Climate Model with Activated Sea Ice Component

Sea ice is strongly impacted by global warming, and its decline further alters the global climate. Climate models are important tools for examining those future sea ice changes and the interaction of sea ice with other Earth system components such as the atmosphere and the ocean. Typically, these components are simulated with separate codes. The interaction between these components is typically mo
