Beboernes opplevelse av middagsmåltidet på sykehjem/helseinstitusjon. Betydningen av sensoriske opplevelser og tilfredshet med måltidsmiljø og middagsmat
(Master thesis; Mastergradsoppgave, 2018-11-30)Underernæring og dårlig matlyst blant sykehjemsbeboere er et aktuelt tema både i media og innenfor helse- og omsorgssektoren. Det er et tilsynelatende fokus på mat og ernæring, men det finnes lite informasjon om hva beboerne selv mener om måltidsituasjonen. Formålet med denne studien er å undersøke hvordan beboere på sykehjem/helseinstitusjon opplever middagsmåltidet basert på individenes sanseinntrykk ... -
Sources of superprofit in a well-regulated fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-23)This study is motivated by the ongoing debate on resource rent taxation in Norwegian fisheries. Drawing on strategy literature, this paper argues that resource rent is just one of several conceivable sources of above-normal profit (superprofit) for a firm in a natural resource-based industry. The financial statements of almost the whole population of the Norwegian purse seine fleet were analyzed (61 ... -
Is the Norwegian cod industry locked into a value-destructive volume logic?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-02)Wild cod is a scarce and valuable natural resource. However, cod fishing along the coast of northern Norway has largely been about fishing as much as possible with the least possible resource effort, and thereby at the lowest cost. This traditional volume logic is rooted in biology, meteorology, and small scale capture technology. The logic is further enhanced by new large scale capture technology ... -
Towards operational sea ice type retrieval using L-band Synthetic aperture radar
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-14)Operational ice services around the world have recognized the economic and environmental benefits that come from the increased capabilities and uses of space-borne Synthetic Aperture Radar (SAR) observation system. The two major objectives in SAR based remote sensing of sea ice is on the one hand to have a large areal coverage, and on the other hand to obtain a radar response that carries as much ... -
Maximilian Hell (1720–92) and the Ends of Jesuit Science in Enlightenment Europe
(Book; Bok, 2020)The Viennese Jesuit court astronomer Maximilian Hell was a nodal figure in the eighteenth-century circulation of knowledge. He was already famous by the time of his celebrated 1769 expedition for the observation of the transit of Venus in northern Scandinavia. However, the 1773 suppression of his order forced Hell to develop ingenious strategies of accommodation to changing international and domestic ... -
The Impact of Additive Noise on Polarimetric RADARSAT-2 Data Covering Oil Slicks
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-14)We attempt to understand how a set of well known polari-metric Synthetic Aperture Radar (SAR) features are impacted by the additive system noise for mineral oil and produced water slicks. For this, we use quad-polarimetric SAR scenes from Radarsat-2. Oil slicks at sea can be detected using SAR instruments, and the dual- (HH-VV) and quad-polarimetric modes can provide additional information about the ... -
The marine sedimentary environments of Kongsfjorden, Svalbard: an archive of polar environmental change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-16)Kongsfjorden, a fjord in north-western Svalbard, is characterized by large environmental gradients driven by meltwater processes along the margins of tidewater glaciers and the inflow of relatively warm Atlantic Water, the main heat source for the European Arctic. These factors make Kongsfjorden a key area to investigate changes in the polar climate–ocean–glacier system and to examine the resulting ... -
Implications of Coastal Darkening for Contaminant Transport, Bioavailability, and Trophic Transfer in Northern Coastal Waters
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-13)The increased transport of terrestrially derived organic material (tOM) from catchments to rivers and lakes is leading to browning of northern freshwaters.(1) Although the same environmental drivers can be expected to lead to widespread increases in tOM and subsequent darkening in adjacent coastal systems,(2) this has received considerably less attention, and long-term monitoring data for detecting ... -
Fisketillatelser og pant - lovfesting av den rettslige løsningen i "Barents Eagle"?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-02)Forfatteren tar utgangspunkt i Thor Falkangers påpekning av svakheter i Høyesteretts syn på fisketillatelser som aksessorium til fiskefartøyet i Rt. 2009 s. 1502 «Barents Eagle». Han reiser spørsmål om Høyesteretts forståelse av fiskerisystemet fortsatt er uttrykk for gjeldende rett, eller om den rettslige subsumsjonen vil være en annen i kjølvannet av senere endringer av fiskerilovgivningen. I ... -

Sodium and Potassium Intake Assessed by Spot and 24-h Urine in the Population-Based Tromsø Study 2015–2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-16)Reduction of salt intake is a public health priority and necessitates the surveillance of salt intake in the population. The validity of salt intake assessed by dietary surveys is generally low. We, therefore, aimed to estimate salt intake by 24-h urine collection and to assess the usefulness of spot urine collection for surveillance purposes. In the population-based Tromsø Study 2015–2016, 493 men ... -
Organically-preserved multicellular eukaryote from the late Neoproterozoic Nyborg Formation, Arctic Norway.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-10)Eukaryotic multicellularity originated in the Mesoproterozoic Era and evolved multiple times since, yet early multicellular fossils are scarce until the terminal Neoproterozoic and often restricted to cases of exceptional preservation. Here we describe unusual organically-preserved fossils from mudrocks, that provide support for the presence of organisms with differentiated cells (potentially an ... -

On the status of Concordantia Temporum in Spanish: An experimental approach
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-23)Subjunctive clauses in Spanish are traditionally claimed to obey Concordantia Temporum (CT), an agreement in tense between the matrix and subjunctive clauses. Treating this phenomenon literally as agreement is problematic, so an analysis in which CT falls out from general principles of tense interpretation, as in Laca (2010a), is very attractive. Nevertheless, this analysis seems to make some <i>prima ... -
En komparativ casestudie om balansert målstyring i en norsk kommune. Et verktøy eller et symbol?
(Master thesis; Mastergradsoppgave, 2019-08-31)Harstad kommune innførte styringsverktøyet balansert målstyring som et resultat av et pilotprosjekt. Konseptet balansert målstyring ble introdusert av Kaplan og Norton på begynnelsen av 1990-tallet. Formålet med balansert målstyring er å operasjonalisere overordnet strategi til både finansielle og ikke-finansielle mål i en samlet ramme, oftest kalt et målekort. I form av en komparativ casestudie ...
