This thesis explores the extent to which the Southern Transitional Council (STC) in Yemen has manifested itself as a partner of the Arab coalition and its aspirations to take the lead in regional and international politics and conflict resolution through the Yemen crisis. It also uses Qualitative Content Analysis to analyze fourteen interviews with key stakeholders and experts from various politic

Genom empiriska exempel från Danmark och Sverige diskuterar denna artikel hur den moderna, masstillverkade cykeln blev ett viktigt verktyg i händerna på en ny generation politiska ungdomar. Under mellankrigsåren (1918–1939) utgjorde de unga sig själva som en egen samhällsgrupp. För allra första gången i historien blev ungdomen nyckelaktörer på den politiska scenen och de tog med sig moderna former

This chapter presents two case analyses, one situated in Sweden and the other in Poland, where attempts have been made to intervene in the existing laws regulating access to abortion. The first case involves the lawsuits filed by midwives in Sweden who claimed to have been discriminated against on the grounds of their religion when they had been turned down for work due to their objection to perfo

In this paper, a novel three-dimensional (3D) irregularshaped geometry-based stochastic model (IS-GBSM) is proposedfor sixth-generation (6G) millimeter wave (mmWave) massivemultiple-input multiple-output (MIMO) vehicle-to-vehicle(V2V) channels. To investigate the impact of vehicular trafficdensity (VTD) on channel statistics, clusters are divided into staticclusters and dynamic clusters, which are

This article addresses the role of the corporate purpose in strategic financial communication from the perspective of investor relations officers (IROs) with particular reference to their sensemaking process. Strategic financial communication increasingly includes intangible assets that contribute to the value of the company. At the same time, more and more companies are publishing corporate purpo

The COST2100 channel model is a reference channel model which provides dynamic multiple-input multiple-output channel responses for radio system simulations. In this paper, channels created by the COST2100 model were compared to channel measurements in order to understand behaviours of the model. Model parameters of the COST2100 model were derived by dynamic double-directional channel measurements

Academic research increasingly focuses on environmental sustainability as a specific societal mission to be addressed. However, the effects of the increasing sustainability orientation on output generation in public research organizations are largely unexplored. In this paper, we analyse the effects of the increasing importance of sustainability-oriented research topics on research and teaching ef

Many people do not act together against climate change or social inequalities because they feel they or their group cannot make a difference. Understanding how people come to feel that they can achieve something (a perception of self-efficacy) is therefore crucial for motivating people to act together for a better world. However, it is difficult to summarize already existing self-efficacy researc

The Russian war of aggression against Ukraine caused an escape of >7 million people to other European countries. In this extreme context, the accommodation of refugees has been an urgent need and an unexpected challenge for the host cities and societies. This short paper discusses insights and learnings on housing and accommodation of Ukraine war refugees at the local scale. It summarises challeng

Based on the Fenchel duality we build a primal-dual framework for minimizing a general functional consisting of a combined L1 and L2 data-fidelity term and a scalar or vectorial total variation regularisation term. The minimization is performed over the space of functions of bounded variations and appropriate discrete subspaces. We analyze the existence and uniqueness of solutions of the respectiv

In the western world, approximately 50% of all cancer patients receive radiotherapy alone or in combination with surgery or chemotherapy. Image-guided radiotherapy (IGRT) has in recent years been introduced to enhance precision of the delivery of radiation dose to tumor tissue. Fiducial markers are often inserted inside the tumor to improve IGRT precision and to enable monitoring of the tumor posi

Normal science is a characterization of science in our epoch and a demarcation of what “scientific” means. It divides science in disciplined/normed paradigms. Mathematical epidemiology is the paradigm that regulates the activity of mathematicians with respect to the study of epidemics. It also represents the interest (multiple meanings implied) of the community that guards it. In contrast, a real

Reliability is becoming increasingly important for many applications envisioned for future wireless systems. A technology that could improve reliability in these systems is massive MIMO (Multiple- Input Multiple-Output). One reason for this is a phenomenon called channel hardening, which means that as the number of antennas in the system increases, the variations of channel gain decrease in both t
