Utvikling av fysisk form hos barn og unge over en 10 års periode : betydningen av deltakelse i fysisk aktivitet og foreldrestøtte
2014
Masteroppgave idrettsvitenskap -Universitetet i Agder 2014 The aim of this master's project was to investigate changes in physical activity levels and relative physical fitness among Norwegian children over a period of 10 years. 55 six year old Norwegian children were tested using a comprehensive test battery from Fjørtoft et al (2011). A questionnaire that was used to answer research questions referred to physical activity and sport participation. The same tests and measurements were performed at 13 years (n = 45) and 16 years (n = 34), (i.e. seven and ten years later, respectively). Experienced parental support in terms of participation in physical activity was also measured. The sample w…
Frikjøreres atferd og egenskaper : en undersøkelse av relasjonen mellom risikotaking, sensation seeking og mental tøffhet på frikjørere
2014
Masteroppgave idrettsvitenskap- Universitetet i Agder 2014 The aim of this study was to determine freeskiers mental toughness, sensation seeking and risk taking behavior and if mental toughness or sensation seeking can predict a risk taking behavior. 37 athletes from The Norway Freeride Cup conducted the questionnaire. A correlation and regression analysis was used to examine the theses. The results showed that freeskiers are mentally tough, sensation seekers and risk takers. Sensation seeking proves to be a predictor for a risk taking behavior. Especially the scale “Boredom Susceptibility” (SS-BS) showed a high correlation to risk taking behavior. Mental toughness could not predict a risk …
Lidenskap for terrengsykling : en studie av relasjonen mellom dualistisk lidenskap, treningsavhengighet og tilfredshet med livet
2014
Masteroppgave idrettsvitenskap Universitetet i Agder , 2014 The aim of this study was to examine the relationship between passion (harmonious and obsessive) for mountain biking and satisfaction with life. In addition, the study examines the dualistic model of passion and its relationship with exercise dependence symptoms. Exercise dependence symptom’s effects on satisfaction with life were also investigated. A total of 990 riders who participated in Grenserittet or Farrisrunden completed the questionnaire. A correlation and regression analysis was used to examine the hypotheses. Results showed that the bike riders who reported a high degree of harmonious passion typically responded higher o…
Imprints of latitude, host taxon, and decay stage on fungus-associated arthropod communities
2022
Interactions among fungi and insects involve hundreds of thousands of species. While insect communities on plants have formed some of the classic model systems in ecology, fungus-based communities and the forces structuring them remain poorly studied by comparison. We characterize the arthropod communities associated with fruiting bodies of eight mycorrhizal basidiomycete fungus species from three different orders along a 1200-km latitudinal gradient in northern Europe. We hypothesized that, matching the pattern seen for most insect taxa on plants, we would observe a general decrease in fungal-associated species with latitude. Against this backdrop, we expected local communities to be struc…
The ecomorphology of southern African rodent incisors: Potential applications to the hominin fossil record.
2018
AbstractThe taxonomic identification of mammalian fauna within fossil assemblages is a well-established component of paleoenvironmental reconstructions. However, many fragmentary specimens recovered from fossil sites are often disregarded as they can be difficult to identify with the precision required for taxonomic methods. For this reason, the large numbers of isolated rodent incisors that are often recovered from hominin fossil bearing sites have generally been seen as offering little interpretive value. Ecomorphological analysis, often referred to as a “taxon-free” method, can potentially circumvent this problem by focusing on the adaptive, rather than the taxonomic significance of rode…
Fungal-Mediated Multitrophic Interactions : Do Grass Endophytes in Diet Protect Voles from Predators?
2009
Plant-associated micro-organisms such as mycotoxin-producing endophytes commonly have direct negative effects on herbivores. These effects may be carried over to natural enemies of the herbivores, but this has been rarely explored. We examined how feeding on Neotyphodium endophyte infected (E+) and endophyte free (E−) meadow ryegrass (Scherodonus pratensis) affects body mass, population size and mobility of sibling voles (Microtus levis), and whether the diet mediates the vulnerability of voles to least weasel (Mustela nivalis nivalis) predation. Because least weasels are known to be olfactory hunters, we also examined whether they are able to distinguish olfactory cues of voles fed on E+ a…
Engagement as a Driver of Growth of Online Health Forums: Observational Study
2017
Background: The emerging research on nurturing the growth of online communities posits that it is in part attributed to network effects, wherein every increase in the volume of user-generated content increases the value of the community in the eyes of its potential new members. The recently introduced metric engagement capacity offers a means of quantitatively assessing the ability of online platform users to engage each other into generating content; meanwhile, the quantity engagement value is useful for quantifying communication-based platform use. If the claim that higher engagement leads to accelerated growth holds true for online health forums (OHFs), then engagement tracking should be…
Etestw versus broth microdilution for ceftaroline MIC determination with Staphylococcus aureus: Results from PREMIUM, a European multicentre study
2017
Objectives: To compare the concordance of ceftaroline MIC values by reference broth microdilution (BMD) and Etest (bioMérieux, France) for MSSA and MRSA isolates obtained from PREMIUM (D372SL00001), a European multicentre study. Methods: Ceftaroline MICs were determined by reference BMD and by Etest for 1242 MSSA and MRSA isolates collected between February and May 2012 from adult patients with community-acquired pneumonia or complicated skin and soft tissue infections; tests were performed across six European laboratories. Selected isolates with ceftaroline resistance in broth (MIC >1 mg/L) were retested in three central laboratories to confirm their behaviour. Results: Overall concordance…
The relationship between Polypharmacy and Trajectories of Cognitive Decline in People with Dementia: a large representative cohort study
2019
Polypharmacy, defined through the number of medications prescribed, has been linked to a range of adverse health outcomes in people with dementia. It is however unclear whether a numerical threshold of concurrently prescribed drugs is a suitable predictor for cognitive decline. We aimed to test associations between polypharmacy and both short-term (six months) and long-term (three years) cognitive trajectories in patients with incident dementia. Using data from a large mental health and dementia care database in South London, a cohort of 12,148 patients (mean age = 80.7 years, 61.1% female, mean MMSE = 18.6) clinically diagnosed with dementia was identified. We determined the number of medi…
Adherence to a Mediterranean diet is associated with lower incidence of frailty: A longitudinal cohort study
2018
Background & aims There is a paucity of data investigating the relationship between the Mediterranean diet and frailty, with no data among North American people. We aimed to investigate if adherence to a Mediterranean diet is associated with a lower incidence of frailty in a large cohort of North American people. Methods This study included subjects at higher risk or having knee osteoarthritis. Adherence to the Mediterranean diet was evaluated using a validated Mediterranean diet score (aMED) as proposed by Panagiotakos and classified into five categories. Frailty was defined using the Study of Osteoporotic Fracture (SOF) index as the presence of ≥2 out of: (i) weight loss ≥5% between b…
