This thesis addresses how verbal comprehension is affected by seeing the speaker and in particular when the speaker is an animated virtual speaker. Two people visually co-present – one talking and the other listening, trying to comprehend what is said – is a central and critical scenario whether one is interested in human cognition, communication or learning. Papers I & II are focused on the e

Control systems can be vulnerable to security threats where an attacker gathers information about the execution of the system. In particular, side-channel attacks exploit the predictability of real-time control systems and of their schedules. To counteract their action, a scheduler can randomize the temporal execution of tasks and limit the amount of information the attacker can gather. Schedule r

The diversity of herbivorous insects may arise from colonization and subsequent specialization on different host plants. Such specialization requires changes in several insect traits, which may lead to host race formation if they reduce gene flow among populations that feed on different plants. Behavioural changes may play a relevant role in host race formation, for example if different races evol

Culture and discourses affect our understanding of the archive in the digital environment: preconceptions, norms, and practices developed in a paper-based administration colour and limit perceptions of digital archives. It can be difficult to reimagine the archive in the context of e-government and the networked environment, where the complexity of archival issues increases. This is a global probl

Traditionally, public records have been handled and preserved by each creating or receiving agency separately. The existing legal framework in Sweden is still based on this principle. However, recent developments – digital technologies paired with new ways of working – create a more dispersed and complex body of archives. What this means for the practical records management can be discussed. This

Lately, evidence for early-Holocene emerging sedentism has been suggested among foragers in Northern Europe. The core of this suggested sedentism lies in the increasing dependency on large-scale fishing and mass consumption of fish and a territorial behaviour associated with access to the best fishing locations. This territoriality might also be associated with increasing numbers of people settlin

High-grade serous ovarian cancer (HGSOC) is the predominant and most lethal histological type of epithelial ovarian cancer. During the last few years, several new treatment options with PARP inhibitors have emerged. The FDA has approved the PARP inhibitor olaparib (Lynparza™) as maintenance treatment after first-line platinum-containing chemotherapy and olaparib, niraparib (Zejula™) and rucaparib

Several toxigenic cyanobacteria produce the cyanotoxin (microcystin). Being a health and environmental hazard, screening of water sources for the presence of microcystin is increasingly becoming a recommended environmental procedure in many countries of the world. This study was conducted to assess the ability of freshwater cyanobacterial species Westiellopsis prolifica to produce microcystins in

Osteoporosis and osteoporosis related fractures are a major health care challenge both in Sweden and globally. The cost and suffering from osteoporosis are expected to increase since the population of elderly is increasing. Bone health can be affected by altered mineral homeostasis, which in its turn can be affected by reduced kidney function. However, the course of age-related decline in kidney f
