Arctic sea-ice diatoms fuel polar marine food webs as they emerge from winter darkness into spring. Through their photosynthetic activity they manufacture the nutrients and energy that underpin secondary production. Sea-ice diatom abundance and biomolecular composition vary in space and time. With climate change causing short-term extremes and long-term shifts in environmental conditions, understanding ...

Sannhets- og forsoningskommisjonen (SFK) la fram sin rapport 1. juni 2023, og definerer det formelle sluttpunktet for statens fornorskningspolitikk overfor samene til 1959/1963. Med utgangspunkt i noen sentrale trekk ved historisk institusjonalisme, som stiavhengighet og kritisk vendepunkt, tar vi i artikkelen for oss denne tidsfastsettelsen og reiser spørsmålet om hvilken politikk overfor samene ...

School teachers are a professional group that are responsible for a large proportion of reports concerning suspected child abuse and neglect. This study looks at which concerns are more often reported by schools and if these reports are more likely substantiated when the school is the reporter. The study was designed as a retrospective case-file study (N = 883). Results show that concerns about the ...

A Cyber-Physical System (CPS) deployed in remote and resource-constrained environments faces multiple challenges. It has, no or limited: network coverage, possibility of energy replenishment, physical access by humans.<p> <p>Cyber-physical nodes deployed to observe and interact with the Arctic tundra face these challenges. They are subject to environmental factors such as avalanches, low temperatures, ...

Food-web structure determines the cycling pathways and fate of new production in marine ecosystems. Herbivorous zooplankton populations are usually seasonally coupled with pelagic primary producers. Synchrony of phytoplankton blooms with reproduction, recruitment and seasonal ascent of their main grazers ensures efficient transfer of organic carbon to higher trophic levels, including commercially ...

This study aimed to examine the cognitive effects of tDCS and the subjective cognitive improvement perceived by patients with schizophrenia. A total of 173 outpatients diagnosed with schizophrenia were recruited for this double-blind, randomized, placebo-controlled trial. Two different stimulation modes were applied: 2 mA 20 minutes active tDCS and sham tDCS. Ten daily sessions over 10 consecutive ...

Background: Children with speech sound difficulties often require educational psychology services, yet systematic reviews examining the association between these difficulties and language or reading problems are lacking. This meta-analysis examines whether these children are at higher risk of language and reading difficulties compared to their peers.<p> <p>Method: The study analyzed 290 effect ...

The study site, small (0.15 ha), shallow (mean depth of 1.5 m; for details see Poliakova et al. 2024) lake Tenndammen(N78°06.118′; E15°02.024′, altitude 5 m above sea level [a.s.l.]) is located about 1 km away from the Greenland Sea shore in the Colesdalen (Coles valley), Svalbard (Spitsbergen, Шпицберген). The research area is known as one of Svalbard’s biodiversity hotspots, with the highest number ...

The SAMINOR Study represents a unique data collection on health and diseases among the multiethnic population – including the Sámi population in Norway – making it a case study for discussing Sámi research data governance in a health context. This article describes how Sámi interests and needs in the SAMINOR Study are governed by two steps of a research application review process consisting of the ...
