The strong time-dependence of the dynamics of galactic bars yields a complex and rapidly evolving distribution of dense gas and star forming regions. Although bars mainly host regions void of any star formation activity, their extremities can gather the physical conditions for the formation of molecular complexes and mini-starbursts. Using a sub-parsec resolution hydrodynamical simulation of a Mil
Although conventional computer technology made a huge leap forward in the past decade, a vast number of computational problems remain inaccessible due to their inherently complex nature. One solution to deal with this computational complexity is to highly parallelize computations and to explore new technologies beyond semiconductor computers. Here, we report on initial results leading to a device
This paper addresses the problems associated with ambitious greenhouse gas (GHG) emission cut-off targets set for cities in recent years. Even though many cities have adopted an active approach to sustainability issues and climate change mitigation, they often lack appropriate and effective tools for achieving the cut-off targets. The primary purpose of this paper is to demonstrate the utilisation
The aim of this article was to investigate presentations of “wet” eldercare facilities in Sweden, a type of facility that provides care for older people with long-term alcohol problems and where the consumption of alcohol is allowed. Wet eldercare facilities challenge traditional Swedish policy on alcohol treatment, and their approach constitutes a breach of mainstream policies on alcohol and trea
This article discusses ineffective knowledge and information communication as an important barrier to improving energy efficiency in small and medium-sized enterprises (SMEs) and considers how to make functional communication an enabler of future SME energy-efficiency programmes. Energy audits – important tools when addressing energy efficiency in companies – are often performed by professionals w
Digital trace data can be used to capture organizational practices in granular detail and enable the automation of a wide range of managerial tasks. One example is Digital Productivity Assistants (DPA) that harness digital trace data about knowledge workers’ performance and make targeted suggestions for how to improve and optimize their work patterns. Previous research shows that despite benevolen
In multi-user multiple-input multiple-output (MU-MIMO) systems, the non-linear behavior of the power amplifiers (PAs) may cause degradation of the linear precoding schemes dealing with interference between user equipments (UEs), e.g., the zero-forcing (ZF) precoder. One way to minimize this effect is to use digital-pre-distortion (DPD) modules to linearize the PAs. However, using perfect DPD modul
Background When projects and programmes are becoming ever more present in many of today’s organizations, these are also playing an increasingly important role in implementing the corporate strategy. This thesis is focusing on internal change initiatives, named BT initiatives, which aims at implementing substantial changes to the current organization. Due to the size of the initiatives and their im
The global increase in overweight and obesity rates represent pressing public health concerns associated with severe comorbidities, amongst a rising incidence and impaired outcome of breast cancer. Yet, biological explanations for how obesity affects breast cancer are incompletely mapped. Herein, the joint impact by differentiated 3T3-L1 adipocytes and obesity-related metabolic conditions on breasThe global increase in overweight and obesity rates represent pressing public health concerns associated with severe comorbidities, amongst a rising incidence and impaired outcome of breast cancer.

Background: This study examines Swedish young adults (age 21) with a history of conduct disorder (CD) in adolescence. Research has established CD as a condition for a range of adverse outcomes. Intelligence, aggression, parent-child conflict, parent-child relation and peer-rejection are known factors influencing the outcome. Aim: The aim of this longitudinal study is to find how self-confidence an
Scenario-based approaches in environmental and policy assessment studies are increasingly applied within integrated assessment and modelling frameworks. The SEAMLESS project develops such an integrated framework (SEAMLESS-IF) aiming to assess, ex-ante, impacts of alternative agro-environmental policies on the sustainability of agricultural systems. A particular challenge in this context is the con
This article asks what key concerns emerge from the way responsibility is framed in United Nations summit documents on the Sustainable Development Goals (SDGs) adopted in 2015. Our conceptual framework serves to make the study of SDG responsibility more systematic by distinguishing three main senses of responsibility: cause, obligation, and accountability. The framework structures our analysis of
Monte Carlo simulations and variational calculations using a Gaussian ansatz are applied to a model consisting of a flexible linear polyelectrolyte chain as well as to an intrinsically stiff chain with up to 1000 charged monomers. Addition of salt is treated implicitly through a screened Coulomb potential for the electrostatic interactions. For the flexible model the electrostatic persistence leng
Flexible multibody dynamics (FMD) has found many applications in control, analysis and design of mechanical systems. FMD together with the theory of structural optimization can be used for designing multibody systems with bodies which are lighter, but stronger. Topology optimization of static structures is an active research topic in structural mechanics. However, the extension to the dynamic case
We investigated the relationship between the affective component (A: the level of offensiveness/intensity) and the behavioral component (B: the frequency of usage) of taboo words that are part of an individual’s natural language (C: the cognitive component). In Study 1, 900 US-residents generated the 10 most common taboo words they use in their daily lives (C).

There exist several datasets for developing self-driving car methodologies. Manually collected datasets impose inherent limitations on the variability of test cases and it is particularly difficult to acquire challenging scenarios, e.g. ones involving collisions with pedestrians. A way to alleviate this is to consider automatic generation of safety-critical scenarios for autonomous vehicle (AV) te
This thesis investigates Swedish crisis management. This thesis aims to contribute to crisis research by providing critical perspectives on the role of knowledge in crisis management settings. The papers in this thesis stem from empirical studies of the major cases of Swedish crisis management during the last decade, including the Swedish refugee crisis in 2015, the wildfires in 2018, and the Covi
