      Nordengen, Kaja; Kirsebom, Bjørn-Eivind Seljelid; Richter, Grit; Pålhaugen, Lene; Gisladottir, Berglind; Siafarikas, Nikias Ioannis; Nakling, Arne Exner; Rongve, Arvid; Bråthen, Geir; Grøntvedt, Gøril Rolfseng; Gonzalez, Fernando; Waterloo, Knut; Sharma, Kulbhushan; Karikari, Thomas; Vromen, Eleonora M.; Tijms, Betty M.; Visser, Pieter J.; Selnes, Per; Kramberger, Milicia G.; Winblad, Bengt; Blennow, Kaj; Fladby, Tormod (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-13)
      Background - Brain innate immune activation is associated with Alzheimer’s disease (AD), but degrees of activation may vary between disease stages. Thus, brain innate immune activation must be assessed in longitudinal clinical studies that include biomarker negative healthy controls and cases with established AD pathology. Here, we employ longitudinally sampled cerebrospinal fluid (CSF) core AD, ...

    • A longitudinal investigation of immigrant children’s ethnic and national identities 

      Froehlich, Laura; Martiny, Sarah E.; Deaux, Kay (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-22)
      How immigrants define their ethnicity and nationality is relevant for integration: They can identify with their ethnic group, the receiving society, and a combination of both. A longitudinal study with elementary-school children with migration background (N = 200; age 9-10) in Germany investigated the predictors and stability of ethnic and national identity. Ethnic identity was more highly endorsed ...

    • Læring av erfaring med snøskredulykke 

      Andersen, Mitra Hofgaard; Bjerkan, Stine Angelica; Jenssen, Jan Petter (Master thesis; Mastergradsoppgave, 2020-12-15)
      Det sies at vi best lærer av våre feil. Hvis man ved høyrisikoaktiviteter som skikjøring i skredterreng lærer best ved å faktisk oppleve en ulykke vil det kunne få alvorlige konsekvenser. Likevel viste studie til Mannberg, Hetland og Pfuhl (2020) at 38% av de som har opplevd snøskredulykke blir tatt gjentatte ganger. Hva lærer vi etter en snøskredulykke? Denne studien hadde fire forskningsspørsmål: ...

    • Male and female immediate fear reaction to white noise in a semi-natural environment: A detailed behavioural analysis of the role of sex and oestrogen receptors 

      Le Moene, Olivia; Ramirez-Renteria, Mayra; Ågmo, Anders j (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-01)
      In classical rodent anxiety models, females usually display lower anxiety than males, whereas anxiety disorders are more prevalent in women. Perhaps this contradiction is caused by the use of behavioural models with low external validity. Therefore, we analysed immediate reactions to a sudden 90-dB white noise in a semi-natural environment. We observed mixed-sex groups of rats for the 60 seconds ...

    • Male rat sexual behavior: Insights from inter-copulatory intervals 

      Huijgens, Patty Thalia; Guarraci, Fay; Olivier, Jocelien; Snoeren, Eelke (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-09)
      The assessment of sexual behavior in male rats with the aim of unraveling underlying neurobiological mechanisms has in the recent decades been reduced to the annotation of mounts, intromissions and ejaculations. To provide a better understanding of the structure and patterns of copulation, it is necessary to extend and tailor the analysis to the natural organization of male rat copulation. This will ...

    • «Mamma, er du mest glad i telefonen eller i meg?» En kvalitativ studie av småbarnsforeldres erfaringer med og forhold til mobilbruk rundt barna 

      Augustson, Anders; Klepaker, Peder Tanke (Master thesis; Mastergradsoppgave, 2021-12-14)
      Det er gjort mye forskning på hvilke innvirkninger småbarnsforeldres mobilbruk kan ha på forelder-barn-interaksjoner og potensielt barns utvikling. Færre studier har undersøkt foreldres holdninger til mobilbruk og blant norske populasjoner er forskningen knapp. Vi gjennomførte en kvalitativ studie med semistrukturerte intervjuer for å undersøke hvilke holdninger småbarnsforeldre har rundt sin egen ...

    • Man Enough to Care: Masculinity Threat and Misfit of Men Studying Communal Occupations 

      Lund, Ingvild Marie Hansen (Mastergradsoppgave; Master thesis, 2023-04-28)
      Fra en ung alder har menn internalisert kjønnsstereotypier av hva det vil si å være en "ekte" mann. Maskulinitetstrussel er frykten en mann opplever når de internaliserte kjønnsstereotypene ikke opprettholdes, de føler at maskuliniteten deres blir truet. I denne studien tar vi sikte på å undersøke om det å fremheve viktigheten av omsorgstrekk for mannlige studenter – men ikke kvinnelige studenter – ...

    • Managers as Moral Leaders: Moral Identity Processes in the Context of Work

      This qualitative study explores how business leaders narrate their personal ways of recognizing, reasoning, and resolving moral conficts and what these stories reveal about their moral identity processes within organizational contexts. Based on interviews with 25 business leaders, 4 moral identity statuses were identifed: achievement (commitment to a personally meaningful moral value framework ...

    • Managing Risk of Non-Communicable Diseases in Women with Bulimia Nervosa or Binge Eating Disorders: A Randomized Trial with 12 Months Follow-Up 

      Mathisen, Therese Fostervold; Sundgot-Borgen, Jorunn; Rosenvinge, Jan H; Bratland-Sanda, Solfrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-03)
      Persons with bulimia nervosa (BN) or binge eating disorder (BED) have an elevated risk of non-communicable diseases (NCDs). However, lowering this risk is rarely addressed in standard cognitive-behavioral treatment (CBT). We aimed to compare CBT with an intervention combining physical exercise and dietary therapy (PED-t), and hypothesized that the PED-t would do better than CBT in lowering the risk ...

      Vasylenko, Olena; Gorecka, Marta Maria; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel, 2018-03-12)
      This study aimed to better characterize age‐related differences in dexterity by using an integrative approach where movement times and kinematics were measured for both hands. Forty‐five young (age 19–31) and 55 healthy older adults (age 60–88) were evaluated during unimanual and bimanual performance of the Purdue Pegboard Test. Gender effects were also assessed. From video‐recorded data, movement ...

    • Manual dexterity in young and healthy older adults. 2. Association with cognitive abilities 

      Vasylenko, Olena; Gorecka, Marta Maria; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-02)
      Currently, little is known about the cognitive constraints underlying manual dexterity decline in aging. Here, we assessed the relationship between cognitive function and dexterity in 45 young and 55 healthy older adults. Effects of gender on the cognition‐dexterity association were also explored. Cognitive assessment comprised neuropsychological tests of executive function, working memory, attention, ...

Our sample consisted of 231 mothers responding in the first data collection that took place June 2020, 97 mothers ...

    • Mate Choice could be Random in Female Rats (Rattus norvegicus) 

      Le Moëne, Olivia; Snoeren, Eelke (Journal article; Tidsskriftartikkel, 2017-11-01)
      Female mate choice is often investigated in terms of reproductive success in order to understand how male characteristics contribute to sexual attractiveness. Previous studies have found that females rats prefer mating with their first encounter rather than males visited subsequently, suggesting that the rewarding value of this first encounter is enough to reinforce mating with the first partner. ...

    • Maternal well-being, mother-child interaction and child psychosocial outcome in the context of HIV/AIDS : a literature review with a keen eye on sub-Saharan Africa 

      Moyo, Kathrine Rasch (Master thesis; Mastergradsoppgave, 2008-11-01)
      The paper reviews the psychosocial literature regarding the impact of maternal HIV on mothers and their uninfected children. Drawing on the ecological theory of Urie Bronfenbrenner, the review proposes a framework that both demonstrates the link between maternal HIV and child psychosocial outcome, and examines the pathways that account for this relationship. Maternal HIV has been found to potentially ...
