    • Middlemen: good for resources and fishermen? 

      Pham, Thi Thanh Thuy; Flaaten, Ola; Skonhoft, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-16)
      This paper studies the role of middlemen in open-access fisheries and how the organization of the supply chains affects resource exploitation and the level and distribution of economic rent. Imperfect competition among middlemen can help ensure that fish stocks are not depleted, which is typically the case in open-access fisheries with competitive markets. Middlemen with market power can also induce ...

      <i>Background</i>: Changes of direction (COD) repeated sprints (RSs) might have greater relevance to football than linear RSs. We aimed to compare the effects of linear and COD RSs on intermittent high intensity running (HIR) over an entire season. <p> <p><i>Methods</i>: In total, 19 high-level male football players (16–19 years) randomly performed linear RSs or COD RSs twice a week during their ...
    • What makes women with food hypersensitivity do self-management work? 

      Jakobsen, Monika Dybdahl; Obstfelder, Aud; Braaten, Tonje; Abelsen, Birgit (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-08)
      <i>Background</i>: Managing a chronic condition takes work, and it is considered important that patients carry out this work. However, knowledge is lacking on what elements enhance self-management work. Persons with food hypersensitivity (FH) seem to do self-management work despite the relatively little support they receive. Our aim is to explore what makes women with FH carry out the work of ...
    • Spasticity, gait, and balance in patients with multiple sclerosis: A cross‐sectional study 

      Norbye, Anja M. Davis; Midgard, Rune; Thrane, Gyrd (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-09)
      <p><i>Objective - </i>More than 80% of people with multiple sclerosis (MS) are affected by spasticity. Spasticity is known to reduce quality of life and contribute to additional symptoms, such as pain and reduced mobility, but the association between spasticity, balance, and mobility has not yet been established. Our aim was to examine whether a relationship exists between spasticity in the lower ...
    • Rodent population cycle as a determinant of gastrointestinal nematode abundance in a low-arctic population of the red fox 

      Mørk, Torill; Ims, Rolf Anker; Killengreen, Siw Turid (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-22)
      We analyzed an 11-year time series (2005–2015) of parasite abundance for three intestinal nematode species in the red fox (<i>Vulpes vulpes</i>) as a function of the multi-annual rodent population cycle in low-arctic Norway, while correcting for other potential covariates that could influence prevalence and abundance. Rodents are paratenic and facultative intermediate hosts for the two Ascarididae ...

    • Dust trajectory simulations around Sun, Vega, and Fomalhaut 

      Stamm, Johann Immanuel; Czechowski, Andrzej; Mann, Ingrid; Baumann, Carsten; Myrvang, Margaretha (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-20)
      <p><i>Context - </i>Vega and Fomalhaut display a thermal emission brightness that can possibly arise from hot dust near the stars, an inner extension of their planetary debris disks. There was brought up an idea that nm-sized dust particles are kept in the vicinity of the stars by electromagnetic forces. This resembles the trapping that model calculations show in the corotating magnetic field in the ...
    • The relationship between the firm's social media strategy and the consumers' engagement behavior in aviation 

      Sigurdsson, Valdimar; Larsen, Nils Magne; Sigfussdottir, Arna Dogg; Fagerstrøm, Asle; Alemu, Mohammed H.; Folwarczny, Michal; Foxall, Gordon R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-05)
      Social media platforms constitute a new frontline for brands to build relationships with their customers. Nevertheless, the literature on social media engagement behavior is unidimensional, as it focuses on customer engagement while neglecting the customer's influence on managerial decisions. The current paper goes a step further by applying the theory of the marketing firm (TMF). We investigated ...

    • Perceptions of assessment in Norwegian occupational therapy students 

      Bonsaksen, Tore; Gramstad, Astrid; Mørk, Gry; Johnson, Susanne Grødem (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      In addition to securing minimum standards of learning among students, assessment is increasingly used as a tool to improve students’ learning. Assessment quality is measured as part of the Course Experience Questionnaire; however, the original ‘appropriate assessment’ scale has demonstrated ambiguous psychometric properties. The current study aimed to gain knowledge about occupational therapy students’ ...
    • Contrasting associations between breeding coloration and parasitism of male Arctic charr relate to parasite species and life cycle stage 

      Johansen, Ida Beitnes; Henriksen, Eirik Haugstvedt; Shaw, Jenny Carolyn; Mayer, Ian; Amundsen, Per-Arne; Øverli, Øyvind (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-23)
      Conspicuous carotenoid ornamentation is considered a signal of individual “quality” and one of the most intensely studied traits found to co-vary with parasitism. Since it has been suggested that only “high quality” individuals have enough resources to express excessive sexual ornaments and resist parasites, current theory struggles to explain cases where the brightest individuals carry the most ...
    • High intensity long interval sets provides similar enjoyment as continuous moderate intensity exercise. The Tromsø Exercise Enjoyment Study 

      Sagelv, Edvard Hamnvik; Hammer, Tord; Hamsund, Tommy; Rognmo, Kamilla; Pettersen, Svein Arne; Pedersen, Sigurd (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-06)
      <i>Objective</i>: High intensity interval exercise sessions with interval sets over 3 min may provide superior cardiorespiratory fitness benefits. To our knowledge, the exercise enjoyment of interval sets over 3 min is not yet elucidated. The aim of this study was to examine exercise enjoyment following one session with four intervals of 4 min high intensity exercise (HIIE) versus one session ...
    • Implications of tag positioning and performance on the analysis of cetacean movement 

      Mul, Evert; Blanchet, Marie-Anne; Biuw, Martin; Rikardsen, Audun H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-17)
      <p><i>Background - </i>Satellite-linked animal-borne tags enable the study of free-ranging marine mammals. These tags can only transmit data while their antenna is above the surface for a sufficient amount of time. Thus, the position of the tag on the animal’s body will likely influence the quality and the quantity of location estimates. We explored the effects of tag placement and tag performance ...
    • Change in physical activity is not associated with change in mental distress among adolescents: The Tromsø Study: Fit Futures 

      Opdal, Ida Marie; Morseth, Bente; Handegård, Bjørn Helge; Lillevoll, Kjersti; Ask, Helga; Nielsen, Christopher Sivert; Horsch, Alexander; Furberg, Anne-Sofie; Rosenbaum, Simon; Rognmo, Kamilla (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-09)
      <i>Background</i>: Previous research shows that physical activity has a protective effect on mental distress in adults, but the relationship is less researched and seems more ambiguous for adolescents. Studies in this field have typically been cross-sectional by design and based on self-reported physical activity measures, which are known to be vulnerable to response bias. The aim of this study ...
