11. Role of the dopamine system in motor skill learning : implications for neurodevelopmental disorders
Sammanfattning : Dopamine (DA), released by midbrain neurons, is critical for motor performance, motor skill learning, and corticostriatal synaptic plasticity. Dysregulation of DAergic signaling in corticostriatal circuitry has also been implicated in several highly heritable neurodevelopmental disorders, such as attention/deficit hyperactivity disorder (ADHD), which are often associated with deficits in fine motor skills.

12. Adopting Information Systems Perspectives from Small Organizations
Sammanfattning : Why do organizations adopt information systems? Is it just because of financial reasons, of concerns for efficiency? Or is it due to external pressures, such as competitor pressure, that an organization adopts an information system?And, how does the adoption take place? Is it a linear process, or is the process one of conflicts? Does a specific person govern this process, or do we have multiple parties involved? What happens if these conflicts occur among those involved? How does the organization move on and achieve a successful information system adoption?By investigating two organizations, one international academic journal and one South American manufacturing company, this thesis aims to investigate the whys and hows of information system adoption, and aims to contribute to the discourse on information system adoptions in small organizations – an often underrepresented segment in information system adoption literature.By adopting different theoretical lenses throughout the five research papers included, this body of work suggests that even when seemingly simple, information system adoptions can become rather complex.

13. Dynamic Modelling of Physical Processes in Magmatic Systems: Dyke Emplacement and Flow-Induced Crystal Rotations
Sammanfattning : The main motivation for this thesis is to develop and improve numerical tools and methods that help further our comprehension of the volcanic plumbing system and its dynamics.The commonly used standard elastic model predicts solutions of dyke shape, thickness, over-pressure and fracturing criteria that do not always fit natural observations.

14. Global Ocean Futures : Governance of marine fisheries in the Anthropocene
Sammanfattning : This PhD thesis provides an analysis of how an adaptive governance approach can be applied to address existing and emerging challenges in global governance with a focus on marine, wild-capture fisheries. All the papers share a coupled social-ecological framing while providing diverse but complementary perspectives. LÄS MER
15. The accessory gene regulator, agr, a system for coordinate control of virulence genes in Staphylococcus aureus
Sammanfattning : Bacterial pathogenicity is generally multifactorial, and genes encoding virulence factors are often subject to coordinate regulation. The regulating systems are supposed to adapt the production of virulence factors in response to changes in the environment during the process of infection. LÄS MER
