    Economic performance has a well-known relationship to political trust. If the economy is perceived as performing well, the levels of political trust are likely to improve. During the 2008 economic crash in Iceland, this relationship seemed vindicated ...

    The ethnic diversity of modern states raises the question of where successful countries are in terms of immigrant inclusion. The number of immigrants in Iceland has increased significantly since 2004, and by the end of 2016, immigrants made up around ...

    The chemical composition of Icelandic rain and snow is dominated by marine aerosols, however human and volcanic activity can also affect these compositions. The six month long 2014–15 Bárðarbunga volcanic eruption was the largest in Iceland for more ...
  • Hess, Jonathan L.; Sigurdsson, Engilbert; Stefansson, Hreinn; Stefansson, Kari (Springer Science and Business Media LLC, 2019-09-06)
    Based on the discovery by the Resilience Project (Chen R. et al. Nat Biotechnol 34:531–538, 2016) of rare variants that confer resistance to Mendelian disease, and protective alleles for some complex diseases, we posited the existence of genetic variants ...
  • Reginsson, Gunnar W.; Ingason, Andrés; Euesden, Jack; Bjornsdottir, Gyda; Ólafsson, Sigurgeir; Sigurdsson, Engilbert; Óskarsson, Högni; Tyrfingsson, Þórarinn; Rúnarsdóttir, Valgerður; Hansdóttir, Ingunn; Steinberg, Stacy; Stefánsson, Hreinn; Gudbjartsson, Daniel; Thorgeirsson, Thorgeir; Stefansson, Kari (Wiley, 2017-02-23)
    We use polygenic risk scores (PRSs) for schizophrenia (SCZ) and bipolar disorder (BPD) to predict smoking, and addiction to nicotine, alcohol or drugs in individuals not diagnosed with psychotic disorders. Using PRSs for 144 609 subjects, including 10 ...
  • Sigurðardóttir, Álfheiður Edda (University of Iceland, School of engineering and natural sciences, Faculty of physical sciences, 2024-09)
    We study the rings of polynomials in several complex variables whose exponents are restricted to the dilates of a compact convex set that contains the origin. We study the properties of weighted extremal functions associated to these polynomial rings, ...
  • Snæbjarnarson, Auðunn (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2019-03-29)
    The first main theme of this thesis is the approximation of holomorphic functions on Stein manifolds by polynomials. In our setting a polynomial is an entire function whose absolute value is bounded from above by $\exp(a\psi+b)$ on the complement of a ...
  • Thorsson, Bolli; Eiriksdottir, Gudny; Sigurðsson, Sigurður; Guðmundsson, Elías Freyr; Bots, Michael L; Aspelund, Thor; Arntzen, Kjell Arne; Mathiesen, Ellisiv B; Gudnason, Vilmundur (BMJ, 2018-05-01)
    Objectives Population statistics for carotid plaque and cardiovascular risk factors reported in scientific journals are usually presented as averages for the population or age and sex adjusted, rather than sex and age groups. Important population ...
  • Jonasson, Jonas Pall (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-01)
    The marine ecosystem around Iceland is shaped by its position in one of the most hydrographically complicated regions of the North Atlantic. The response of marine populations to those diverse conditions is expected to be different across taxonomically ...
  • Southon, Sara B.; Beres, Stephen B.; Kachroo, Priyanka; Saavedra, Matthew Ojeda; Erlendsdóttir, Helga; Haraldsson, Gunnsteinn; Yerramilli, Prasanti; Pruitt, Layne; Zhu, Luchang; Musser, James M.; Kristinsson, Karl G. (American Society for Microbiology, 2020-06-10)
    Resistance to macrolide antibiotics is a global concern in the treatment of Streptococcus pyogenes (group A Streptococcus [GAS]) infections. In Iceland, since the detection of the first macrolide-resistant isolate in 1998, three epidemic waves of ...
  • Eyþórsson, Elías (University of Iceland, School of Health Sciences, Faculty of Medicine, 2019-06-05)
    Streptococcus pneumoniae is a Gram-positive diplococcus that is both a commensal bacterium in the upper respiratory tract of humans, and a common pathogen. The infectious manifestations of pneumococci span a range from benign to serious; from acute ...
  • Cerezo-Araujo, Maite (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2024-05)
    Population numbers result from the combined effect of exogenous (weather, food, predation, anthropogenic impact) and endogenous (behaviour, density) factors on the population, which often act simultaneously resulting in spatial variation in population ...
  • LeBlanc, Nathalie M.; Stewart, Donald T.; Pálsson, Snæbjörn; Elderkin, Mark F.; Mittelhauser, Glen; Mockford, Stephen; Paquet, Julie; Robertson, Gregory J.; Summers, Ron W.; Tudor, Lindsay; Mallory, Mark L. (Wiley-Blackwell, 2017-03-31)
    The Purple Sandpiper (Calidris maritima) is a medium-sized shorebird that breeds in the Arctic and winters along northern Atlantic coastlines. Migration routes and affiliations between breeding grounds and wintering grounds are incompletely understood. ...

    Sediment cores from Kløverbladvatna, a threshold lake in Wahlenbergfjorden, Nordaustlandet, Svalbard were used to reconstruct Holocene glacier fluctuations. Meltwater from Etonbreen spills over a threshold to the lake, only when the glacier is significantly ...
  • Brader, Martin D.; Lloyd, Jeremy M.; Barlow, Natasha L.M.; Norddahl, Hreggvidur; Bentley, Michael J.; Newton, Anthony J. (Elsevier BV, 2017-08)
    Relative sea-level (RSL) data provide constraints on land uplift associated with former ice loading and can be used to differentiate between contrasting ice unloading scenarios. Isolation basin, coastal lowland and geomorphological evidence is employed ...
  • Sigurjónsdóttir, Æsa (University of Iceland, School of Humanities, Faculty of History and Philosophy, 2023-10)
    To travel north has always been a challenge for the explorer, the natural scientist, the poet, the cartographer, the photographer, and the artist. Long present in the European imaginary, Iceland’s natural phenomena has functioned to affirm an idea of ...
