    Nútímakenningar um skólastjórnun beina kastljósinu m.a. að sýn skólastjóra á hlutverk sitt, þeim gildum sem hafa áhrif á starfshætti þeirra (Begley, 2004; Branson, 2005) og hvernig þeir forgangsraða verkefnum sínum. Á síðasta aldarfjórðungi hafa ...
  • Dini, Kevin Tanguy Elian (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2018)
    Light matter coupling is a eld that has rapidly grown in the past decades to become one of the most important interdisciplinary research subject. It combines the phenomena of condensed matter and quantum optics and brings a new panel of unique e ects. ...
  • Larranaga, Nicolas; Valdimarsson, S.K.; Linnansaari, T.; Steingrímsson, Stefán Óli (Wiley, 2018-02-28)
    Streams fluctuate in water flow because of natural (e.g., rain) and human‐induced events (e.g., hydropeaking). Magnitude, frequency, and predictability of these events can have drastic consequences for fish populations. We studied how rapid modifications ...

    Objective Few studies have explored the potential interrelated associations of screen time and physical activity with mental health in youth, particularly using objective methods. We examined cross-sectional associations of these variables among ...
  • Kokorsch, Matthias; Karlsdóttir, Anna; Benediktsson, Karl (Springer Nature, 2015-10-14)
    Icelandic fisheries have gone through tremendous changes since the 1980s and the gradual implementation of individual transferable quotas. The paper investigates to what extent the power of different stakeholders in the fisheries management system ...

    Acute pancreatitis (AP) is one common clinical acute abdominal disease, for which specific pharmacological or nutritional therapies remain elusive. Lactose, a macronutrient and an inducer of host innate immune responses, possesses immune modulatory ...
  • Huang, Guo-yuan; Ohlsson, Tommy; Zhou, Shun (American Physical Society (APS), 2018-04-05)
    We investigate possible interactions between neutrinos and massive scalar bosons via g ϕ ¯ ν ν ϕ (or massive vector bosons via g V ¯ ν γ μ ν V μ ) and explore the allowed parameter space of the coupling constant g ϕ (or g V ) ...

    Background The term Asthma and COPD Overlap (ACO) describes a condition where asthma and COPD overlap. We aimed to investigate associations between ACO and insomnia and respiratory symptoms, and to investigate the prevalence of ACO and the characteristics ...
  • Edvardsson, Kristinn Nikulás; Păstrăv, Cezara; Benediktsson, Karl (Elsevier BV, 2018-08)
    Consolidation of the fishing industry worldwide is an issue heavily debated among scholars. Many economists have argued for its necessity, while others – such as sociologists, anthropologists and geographers – have pointed out negative effects of ...

    Lava flows pose a hazard in volcanic environments and reset ecosystem development. A succession of dated lava flows provides the possibility to estimate the direction and rates of ecosystem development and can be used to predict future development. We ...

    Hekla volcano is known to have erupted at least 23 times in historical time (last 1100 years); often producing mixed eruptions of tephra and lava. The lava flow volumes from the 20th century have amounted 80% to almost 100% of the entire erupted ...

    Lava flow thicknesses, volumes, and effusion rates provide essential information for understanding the behavior of eruptions and their associated deformation signals. Preeruption and posteruption elevation models were generated from historical stereo ...
  • Xiaxia Di (University of Iceland, School of Health Sciences, Faculty of Pharmaceutical Sciences, 2019-01-07)
    A substantial diversity of secondary metabolites from marine invertebrates has been described; however, only a few studies have investigated secondary metabolites of marine invertebrates collected in Icelandic waters. The unique marine environment ...
