Polare maskuliniteter

Hauan, Marit Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)

Abstract:

In this paper my aim is to read and understand the journal of Gerrit de Veer from the last journey of William Barents to the Arctic Regions in 1596 and the journal of captain Junge on his hunting trip from Tromsø to Svalbard in 1834.It is nearly 240 years between this to voyages. The first journal is known as the earliest report from the arctic era. Gerrit de Veer adds instructive copper engravings to his text and give us insight in the crews meeting with this new land. Captain Junges journal is found together with his dead crew in a house in a fjord nearby Ny-Ålesund and has no drawings, but word. Both of these journals may be read as sources of the knowledge and understanding of the polar region. They might also unveil the ideas of how to deal with and survive under the challenges that is given. In addition one can ask if the sources can tell us more about how men describe their challenges. Can the way they expressed themselves in the journals give us an understanding of masculinity? And not least help us to create good questions of the change in the ideas of masculinities which is said to follow the change in understanding of the wilderness.

Range shifts and global warming: ecological responses of Empetrum nigrum L. to experimental warming at its northern (high Arctic) and southern (Atlantic) geographical range margin

Buizer, B; Weijers, S; van Bodegom, PM; Alsos, Inger Greve; Eidesen, Pernille Bronken; van Breda, J; de Korte, M; van Rijckevorsel, J; Rozema, J (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)

Abstract:

Global change is expected to lead to range shifts of plant species. The ecological mechanisms underpinning these shifts are currently not well understood. Here, we compared ecological responses possibly underlying southern range contraction and northern range expansion of Empetrum nigrum, a key species in northern heathlands, which may be related to global change. We hypothesized a negative response to warming in the ‘south’ (i.e. the Netherlands) and a positive response at the northern range margin (the tundra on Svalbard). Open top chambers (OTCs) were used to simulate global warming. In the ‘south’, OTC warming caused enhanced shoot growth and growth rate, biomass increment, advanced phenology, larger and heavier berries of Empetrum, while its growing season was extended by 75 days. Under OTC warming co-occurring Calluna vulgaris also showed an increased growing season length (by 98 days) as well as increased shoot growth rate and biomass growth, plant cover and height. Still, we found no evidence for increased competitiveness relative to Empetrum. In the ‘north’, Empetrum responded with increased shoot and biomass growth, enhanced berry development and ripening to warming. These responses exceeded those of co-occurring Cassiope tetragona with the exception of its biomass response. The direct and indirect ecological responses found do not readily explain the observed northward retreat of Empetrum at the southern range margin. The direct ecological responses found at its northern range margin are, on the other hand, in line with the increased occurrences of this species on Svalbard.

Recent decline in body condition of departing Common Guillemots Uria aalge at Hornøya, North Norway

Barrett, Robert T (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)

[+]

[-]

Abstract:

Since 1980, there has been large variation and a recent decline in the mass and body condition of Common Guillemot Uria aalge chicks departing from the nest site in NE Norway. This may be related to deterioration in the feeding conditions off the colony and is alarming considering the critically endangered status of the species in Norway. To measure body condition, earlier studies have caught, weighed and measured guillemot chicks either while still on the breeding site or as they leave the colony. This study emphasises the importance of choosing and defining which method to use as they give different results.

Roald Amundsen : fortellinger om en polarhelt

Aarekol, Lena (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)

[+]

[-]

Abstract:

2011 is the Nansen-Amundsen Year in Norway. This year celebrate two anniversaries with great significance for Norway. It is 150 years since the birth of Fritdjof Nansen and 100 years since Roald Amundsen, accompanied by four of his men, arrived as the first at the South Pole. During this year several new exhibitions has been made and displayed in different museums in Norway. The article surveys the role of today’s museums has in forming the narratives about the Norwegian polar history, the polar heroes and Roald Amundsen especially. An examination of a so called traditional Polar exhibition shows that their main focus on artifacts and their lack of contextualization, gives the exhibition an aura of authenticity. While new exhibitions are characterized by emphasis on contextualization, critical questions and giving different groups a voice. It is argued that the museums both contributes to conserve the prevailing concepts and representations, but also contributes to give new understandings and perspectives of Roald Amundsen and the Norwegian Polar history. It is important to understand how the museums exhibitions are contributing to the collective memory.

Synthetic Aperture Focusing of Ultrasonic Data From Multilayered Media Using an Omega-K Algorithm

Skjelvareid, Martin H.; Olofsson, Tomas; Birkelund, Yngve; Larsen, yngvar (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)

[+]

[-]

Abstract:

The synthetic aperture focusing technique (SAFT) is used to create focused images from ultrasound scans. SAFT has traditionally been applied only for imaging in a single medium, but the recently introduced phase shift migration (PSM) algorithm has expanded the use of SAFT to multilayer structures. In this article we present a similar focusing algorithm called multi-layer omega-k (MULOK), which combines PSM and the ω-k algorithm to perform multilayer imaging more efficiently. The asymptotic complexity is shown to be lower for MULOK than for PSM, and this is confirmed by comparing execution times for implementations of both algorithms. To facilitate the complexity analysis, a detailed description of algorithm implementation is included, which also serves as a guide for readers interested in practical implementation. Using data from an experiment with a multilayered structure, we show that there is essentially no difference in image quality between the two algorithms.

Teater på tvers i høyere utdanning. Studenters praksiserfaringer som teater i undervisningen.

Eriksen, Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)

[+]

[-]

Abstract:

I artikkelen beskrives og diskuteres to prosjekter der dramastudenter har produsert teater på bakgrunn av profesjonsstudenters praksiserfaringer, og de ferdige produktene har blitt brukt i utdanningen av nye studenter. Hvordan studenter kan bidra gjensidig til hverandres læring, på tvers av profesjonsutdanninger, fakulteter og faggrenser, er artikkelens problemstilling. Gjennom observasjon, filmdokumentasjon, intervju og skriftlige tekster dokumenteres det at studentene har opplevd prosjektene både som motiverende og faglig relevante. Teorigrunnlaget for diskusjon av prosjektene er frigjørende teater og frigjørende pedagogikk.

The moose throat bot fly Cephenemyia ulrichii larvae (Diptera: Oestridae) found developing in roe deer (Capreolus capreolus) for the first time

Isomursu, Marja; Nilssen, Arne C.; Oksanen, Antti (Journal article; Tidsskriftartikkel; Peer reviewed, 02-Jun-2008)

Abstract:

About fifty larvae of Cephenemyia ulrichii Brauer (Diptera: Oestridae), some of them nearly fullgrown third instars, were found in the throat of a roe deer (Capreolus capreolus) in June 2007 near Helsinki in Finland. The parasite is considered to be host specific, occurring only in the moose (Alces alces), and this paper is apparently the first report of a successful infestation in an aberrant host.

Trans-Atlantic genetic uniformity in the rare snowbed sedge Carex rufina

Westergaard, Kristine; Alsos, Inger Greve; Engelskjøn, Torstein; Flatberg, Kjell Ivar; Brochmann, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)

[+]

[-]

Abstract:

The red-listed, amphi-Atlantic sedge Carex rufina is highly specialized to certain alpine snowbeds, and threatened by current changes in snow cover duration and moisture conditions. Here we address its range-wide genetic diversity, history, and conservation using amplified fragment length polymorphisms (AFLPs). Despite extensive primer testing, we detected very low overall diversity (4.1% polymorphic markers). Only a single AFLP phenotype was found throughout Norway and across the Atlantic to Iceland and Greenland, while another was found in Canada, suggesting glacial survival in one East and one West Atlantic refugium. East Atlantic C. rufina has probably been heavily bottlenecked in a small refugium, possibly situated within the maximum limits of the ice sheets. Its lack of diversity is likely maintained through local clonal growth causing longevity of genotypes. Habitat availability appears as the main limiting factor for C. rufina, and its currently occupied habitats need to be preserved to ensure its long-time survival.

Tønsnes havn, Tromsø kommune, Troms : rapport fra arkeologiske utgravninger i 2008 og 2009

Skandfer, Marianne; Grydeland, Sven Erik; Henriksen, Siv; Nilsen, Roy Anders; Valen, Christian Roll (Research report; Forskningsrapport, 2010)

[+]

Abstract:

Utgravningene av totalt elleve lokaliteter på Skarpeneset i 2008, med et begrenset tillegg i 2009, avdekket overraskende fire store, rektangulære tufter, mer eller mindre nedgravde i bakken, på to av lokalitetene. Tuftene er datert samlet til 7000 – 6500/6400 f.Kr. Det foreslås at de er rester etter hus med parvis skråstilte, takbærende stolper, uten markerte ildsteder og med minst to åpninger/innganger. Til tross for klare likhetstrekk framviser tuftene relativt stor morfologisk variasjon med hensyn til størrelse, form, grad og form på nedgravning i gulvet, konstruksjon av vegger, samt rominndeling. Markkjemiske analyser viser at enkelte av veggene ble brukt som avfallsområder (møddinger). Funnmaterialet var konsentrert innenfor og i veggene på tuftene. Harde bergarter, inkludert flint fra lokale morenemasser, kvarts, kvartsitt og chert, dominerer. Redskapsmaterialet består av avslag med ulike typer retusj, flekker, mikroflekker, noen få tverrspisser, stikler og bor. Flekke- og mikroflekkekjerner finnes i materialet, men vanligst er bipolare kjerner. Funn av en liten, slipt skiferøks og fragmenter av to andre økser kan muligens ses i sammenheng med påvist sekundær bruk. De resterende ni lokalitetene som ble utgravd i 2008 ga lite informasjon til kulturhistoria for Skarpeneset.

Unintended consequences: how the recovery of sea eagle Haliaeetus spp. populations in the northern hemisphere is affecting seabirds

Hipfner, Mark J.; Blight, Louise K.; Lowe, Roy W.; Wilhelm, Sabina I.; Robertson, Gregory J.; Barrett, Robert; Anker-Nilssen, Tycho; Good, Thomas P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)

Abstract:

The recovery of sea eagle Haliaeetus spp. populations in the temperate northern hemisphere in the closing decades of the 20th century is one of the great conservation success stories of recent times, but the re-establishment of these apex predators in marine systems has had consequences for seabirds. Sea eagles affect seabirds both directly (by taking adults and offspring and by inducing potentially costly behaviors to minimize danger) and indirectly (by facilitating the nest predators of seabirds, mainly gulls and corvids). Repeated disturbance by hunting eagles has caused seabirds to abandon colonies and subcolonies in the tens to hundreds of thousands of pairs. In recent years, sea eagles have been widely implicated in local declines of surface-nesting seabirds in the northeast Pacific Ocean, the northwest Atlantic Ocean and northern Europe. The extent to which recent events simply reflect a return to a more “natural” ecological baseline as sea eagle populations recover from decades of persecution and chemical pollutants is discussed. We argue that there is need for a research effort to investigate the conservation implications of increasing sea eagles in the context of multiple threats to seabird populations.

Virological and serological surveillance for type A influenza in the black-legged kittiwake (Rissa tridactyla)

Tønnessen, Ragnhild; Germundsson, Anna; Jonassen, Christine M; Haugen, Irene; Berg, Kristin; Barrett, Robert; Rimstad, Espen (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)

Abstract:

The epidemiology of avian influenza viruses (AIVs) in gulls is only partially known. The role of the world's most numerous gull species, the black-legged kittiwake (Rissa tridactyla), as a potential AIV reservoir species has been unclear. The prevalence of AIV and humoral response against AIV were therefore studied in a colony of apparently healthy black-legged kittiwakes breeding in a nesting cliff in the South West Barents Region of Norway (70°22' N, 31°10' E), in 2008 and 2009. AIVs were detected from the oropharynx and cloaca in low amounts, with prevalences of 15% and 5%, in 2008 and 2009, respectively. Direct, partial sequencing of the hemagglutinin (HA) gene revealed that the H4 subtype was present. In 2009, antibodies to influenza A virus were detected in sera from 57 of 80 adult birds. In contrast, none of the three-week-old chicks (n = 18) tested seropositive. Hemagglutination inhibition (HI) assays demonstrated that the adult kittiwakes primarily had antibodies specific to the gull-associated H13 and H16 subtypes, with antibodies to H16 being most common. These results support that the highly pelagic black-legged kittiwake is a reservoir of AIV. The serological findings suggest that H16 might be the main AIV subtype in the black-legged kittiwake. Further studies are needed to understand the ecology of AIV in the black-legged kittiwake and in gulls in general.

"Lærerforum". Læreres bruk av og vurdering av et nettbasert veiledningstilbud.

Lund, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)

[+]

[-]

Abstract:	Mange tiltak foreslås for å ruste norske lærere til å møte stadig større pedagogiske utfordringer. Nettbasert veiledning er ett slikt tiltak, og forventningene til de teknologibaserte løsningene har vært store. Imidlertid mangler forskning på hvordan lærere anvender, og vurderer tilbud om nettbasert faglig støtte. Artikkelen belyser funn fra en studie av læreres bruk av det nettbaserte veiledningstilbudet ”Lærerforum”. Lærerne vurderer forumets relevans som høy, men er mer tilbakeholdne i sin vurdering av effekt av å bruke forumet. Videre ser man at bruk av et nettbasert veiledningsforum ikke synes å fortrenge faglige samtaler med kolleger. Nyansene i funnene gir viktig informasjon for videre utvikling av lignende tilbud.
