    • The Role of the Three Rs in Improving the Planning and Reproducibility of Animal Experiments 

      Smith, Adrian John; Lilley, Elliot (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-14)
      Efforts to improve the design of animal studies have tended to focus on the more mathematical aspects, such as randomization, blocking and statistical analysis. There are, however, many other factors that affect the data from preclinical studies. To improve validity, scientists must collaborate closely with the animal facility involved as soon as the decision to use animals has been made. Such ...
    • Role of the “differently-abled” researcher: Challenges and solutions in inclusive research 

      Melbøe, Line (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-30)
      This article examines the role of the “differently-abled” researcher in facilitating inclusive research with adults (age 16 and older) with intellectual disabilities living in Sami areas of Norway. Topics discussed include challenges that may arise while conducting such research due to the nature of the project (externally-funded pre-existing project), methods applied (quantitative) and people ...
    • Role of transfer functions in PSO to select diagnostic attributes for chronic disease prediction: An experimental study 

      Malakar, Samir; Sen, Swaraj; Romanov, Sergei; Kaplun, Dmitrii; Sarkar, Ram (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-22)
      Particle Swarm Optimization (PSO) is a classic and popularly used meta-heuristic algorithm in many reallife optimization problems due to its less computational complexity and simplicity. The binary version of PSO, known as BPSO, is used to solve binary optimization problems, such as feature selection. Like other meta-heuristic optimization techniques designed on the continuous search space, PSO ...
    • The role of trust in sustainable management of land, fish, and wildlife populations in the Arctic 

      Schmidt, Jennifer Irene; Clark, Douglas; Lokken, Nils; Lankshear, Jessica; Hausner, Vera Helene (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-01)
      Sustainable resource management depends on support from the public and local stakeholders. Fish, wildlife, and land management in remote areas face the challenge of working across vast areas, often with limited resources, to monitor land use or the status of the fish-and-wildlife populations. Resource managers depend on local residents, often Indigenous, to gain information about environmental ...

      Flygel, Trym Thune (Master thesis; Mastergradsoppgave, 2019-06-01)
      Objectives: To systematically review existing literature on what role history of tuberculosis (TB) plays in lung function abnormalities and the development of chronic lung disease of HIV infected children and adolescents in Africa, as the burden of paediatric HIV and TB coinfection is the highest in this region. Methods: Systematic searches were performed in PubMed and EMBASE databases using PICO ...
    • The role of ultrasonic vocalizations in the formation of rat groups in a semi-natural environment 

      Skagen, Bjørn (Master thesis; Mastergradsoppgave, 2018-05-03)
      This study investigated if ultrasonic vocalizations (USV) had an effect on the formation of groups of rats in a semi-natural setting that allowed the rats to live closer to their natural state in the wild. This was done by letting four groups of rats into a semi-natural environment. Where prior to release into the environment, all the rats received surgery. Where some of the rats had the nerve to ...
    • The role of underspecification in grammar 

      Lohndal, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-17)
      In order to understand the human ability for language, we cannot simply focus on the idealized monolingual speaker or signer (Chomsky, 1965). Rather, as much work in second language acquisition has recognized, it is also necessary to study instances where a person masters two or more languages at different levels of proficiency. Today’s globalized world with increased migration will further ...
    • The role of variety seeking in consumers’ fish consumption: a study in Sri Lanka 

      Salpage, Nesha Dushani (Master thesis; Mastergradsoppgave, 2011-05-16)
      The primary purpose of this study was to explore the role of variety seeking behaviour towards fish consumption frequency. Second, it aimed to investigate how personality related factors; variety seeking tendency (related to food and personality) and perceived behavioural control affect the nature of variety seeking behaviour. Third, to investigate how product and motivational related factors; ...
    • Role of Virus-Induced Host Cell Epigenetic Changes in Cancer 

      Pietropaolo, Valeria; Prezioso, Carla; Moens, Ugo (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-03)
      The tumor viruses human T-lymphotropic virus 1 (HTLV-1), hepatitis C virus (HCV), Merkel cell polyomavirus (MCPyV), high-risk human papillomaviruses (HR-HPVs), Epstein-Barr virus (EBV), Kaposi’s sarcoma-associated herpes virus (KSHV) and hepatitis B virus (HBV) account for approximately 15% of all human cancers. Although the oncoproteins of these tumor viruses display no sequence similarity to one ...
    • The role of Vitamin D binding protein, total and free 25-hydroxyvitamin D in diabetes 

      Jorde, Rolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-19)
      Vitamin D is important for bone health, but may also have extra-skeletal effects. Vitamin D and its binding protein DBP have immunological effects and may therefore be important in the development of type 1 diabetes (T1DM), and low serum levels of 25-hydroxyvitamin D (25(OH)D) are associated with later development of type 2 diabetes (T2DM). However, it has so far been difficult to convincingly show ...
    • The role of water mass advection in staging of the Southern Ocean Salpa thompsoni populations 

      Henschke, Natasha; Espinasse, Boris Dristan; Stock, Charles A.; Liu, Xiao; Barrier, Nicolas; Pakhomov, Evgeny A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-01)
      Salpa thompsoni is an important grazer in the Southern Ocean. Their abundance in the western Antarctic Peninsula is highly variable, varying by up to 5000-fold inter-annually. Here, we use a particle-tracking model to simulate the potential dispersal of salp populations from a source location in the Antarctic Circumpolar Current (ACC) to the Palmer Long Term Ecological Research (PAL LTER) study ...
    • The role of white wing bands in parental care and mate choice in the female Common eider (Somateria mollissima) 

      Hoholm, Marte Sørbø (Master thesis; Mastergradsoppgave, 2008-11-15)
      The female Common eider (Somateria mollossima) is a drab, lightly coloured bird, easily distinguished from the brightly ornamented male. Unlike the male, the female has white bands on the tips of her wings, and these white wing bands have been shown to reflect individual quality in previous studies. In this study the potential role of the white wing bands in parental care and mate choice is studied, ...
    • THE ROLE OF WORK AND THE SENSE OF ECONOMIC FREEDOM AMONG REFUGEE WOMEN WITH FAMILIES IN TROMSØ, NORWAY 

      Ofosuhene, Adjoa Korankyiwa (Mastergradsoppgave; Master thesis, 2023-05-14)
      The thesis reflects on the discussions surrounding refugee participation in work. Furthermore, the thesis seeks to find out the experiences of refugee women after five years of work participation. Focusing on their personal empowerment, relationship with children, changing ideals about femininities across transnational spaces, and creation of social networks, the thesis explores how these factors ...
    • Role of zero-point vibrational corrections to carbon hyperfine coupling constants in organic pi radicals 

      Chen, Xiao; Rinkevicius, Zilvinas; Ruud, Kenneth; Ågren, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      By analyzing a set of organic π radicals, we demonstrate that zero-point vibrational corrections give significant contributions to carbon hyperfine coupling constants, in one case even inducing a sign reversal for the coupling constant. We discuss the implications of these findings for the computational analysis of electron paramagnetic spectra based on hyperfine coupling constants evaluated at the ...
    • The role of “green” licences in defining environmental controls in Norwegian salmon aquaculture 

      Nikitina, Ekaterina (Master thesis; Mastergradsoppgave, 2015-05-14)
      The study examines the problem of externalities in the Norwegian aquaculture sector. The two main environmental challenges of Norwegian salmon aquaculture at the moment are the sea lice spread and farmed fish escape. Without dealing with these challenges, no increase in production was possible. At the same time the growth in the output is needed to satisfy the increasing demand for salmon products ...
    • Roles for advisory science in the International Council for the Exploration of the Sea (ICES) 

      Linke, Sebastian; Nielsen, Kåre Nolde; Ramirez-Monsalve, Paulina (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-12)
      What role should science take when providing advice in support of policy and politics? Should a provider of science-based advice have its own position on the issues it provides advise on? Or should it be as impartial as possible from the value and policy context of the advice? This theme, long debated, gained new attention in fisheries and marine governance. Starting from theoretical concepts and ...
    • The roles of brain lipids and polar metabolites in the hypoxia tolerance of deep-diving pinnipeds 

      Martens, Gerrit A.; Geßner, Cornelia; Folkow, Lars; Creydt, Marina; Fischer, Markus; Burmester, Thorsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-14)
      Lipids make up more than half of the human brain's dry weight, yet the composition and function of the brain lipidome is not well characterized. Lipids not only provide the structural basis of cell membranes, but also take part in a wide variety of biochemical processes. In neurodegenerative diseases, lipids can facilitate neuroprotection and serve as diagnostic biomarkers. The study of organisms ...
    • Roles of human papillomavirus (HPV) and human immunodeficiecyvirus (HIV) in cervix uteri cancer 

      Moatshe, Gilbert B. (Master thesis; Mastergradsoppgave, 2002-08)
    • The Roles of Light Absorbing Particles in the Norwegian Arctic Snow 

      Olanrewaju, Olasubomi Quadri (Mastergradsoppgave; Master thesis, 2023-05-08)
      Light absorbing particles (LAPs) such as black carbon (BC) and dust can reduce snow albedo and have a positive radiative forcing. Previous studies investigating LAP in snow in Tromsø focused on black carbon (BC) also called elemental carbon because it has human sources, but dust should also be considered because, while largely from natural sources, it is present in higher concentrations. To quantify ...
    • The roles role play plays : The form and function of bilectal codeswitching in North Norwegian pre-school children’s role play 

      Strand, Bror-Magnus S. (Doctoral thesis; Doktorgradsavhandling, 2022-08-25)
      It is well known that Norwegian children code-switch from their native dialect to something resembling Central or Standard East Norwegian in their in-character role utterances during role play. Despite this, the structural aspects of the phenomenon are not exhaustively studied and understood, and the function of this role-play register as a tool for communication in role play deserves further ...
