Å gjøre «det som er liksom planen, da» – en kvalitativ intervjustudie av skolestress blant unge jenter som et strukturelt problem
2021
Stress blant jenter ser ut til å være knyttet til press om å gjøre det bra på skolen og er videre relatert til psykiske plager. I denne artikkelen undersøker vi hvordan skolestress arter seg i unge jenters hverdagsliv, og hvilke institusjonelle prosesser jentenes erfaringer inngår i. Vi tar utgangspunkt i 22 intervjuer med 10 jenter på 10. trinn fra skoler i Norge og beskriver vurderingsarbeid – deres tankearbeid og gjøremål som er knyttet til testing, vurdering og individuell forbedring. Vi drøfter skolestresset og vurderingsarbeidet elevene gjør opp mot prinsippene om tydelig vurderingskultur og forbedring i skolen slik som det kommer fram gjennom den pedagogiske satsingen Vurdering for l…
Multi-parameter analysis of the obstacle scattering problem
2022
Abstract We consider the acoustic field scattered by a bounded impenetrable obstacle and we study its dependence upon a certain set of parameters. As usual, the problem is modeled by an exterior Dirichlet problem for the Helmholtz equation Δu + k 2 u = 0. We show that the solution u and its far field pattern u ∞ depend real analytically on the shape of the obstacle, the wave number k, and the Dirichlet datum. We also prove a similar result for the corresponding Dirichlet-to-Neumann map.
Intern kommunikasjon i Glencore Nikkelverk
2016
Masteroppgave samfunnskommunikasjon- Universitetet i Agder, 2016 Denne masteroppgaven omhandler intern kommunikasjon i Glencore Nikkelverk i Kristiansand. Fokuset er rettet mot interne kommunikasjonsmedier og mediebruk i avdelingene Nikkelelektrolysen og Kontrollrommet. Undersøkelsen omfatter i tillegg ansattes erfaringer med interne kommunikasjonsmedier og ansattes meninger om informasjon som gjelder sikkerhet og forbedringsarbeid. Nikkelverket jobber kontinuerlig med forbedringer som øker produktiviteten, samtidig er sikkerhet det viktigste bedriften fokuserer på hver dag. Bedriften benytter rundt 10 ulike medier for å formidle denne informasjonen til sine ansatte. Disse mediene brukes i …
Självbedömning av muntlig kommunikationskompetens
2016
Tutkielman tarkoituksena oli kartoittaa kahdeksan lukio-opiskelijan käsityksiä itsearvioinnista B1-ruotsissa ja verrata heidän itsearviointejaan suullisessa kommunikaatiotaidossa opettajan antamaan arvioon. Lisäksi tavoitteena oli testata ja arvioida uusimman opetussuunnitelman taitotasoasteikon mukaan luotua itsearviointilomaketta. Itsearviointilomake, opettajan arviointilomake sekä kaikkien tutkimushenkilöiden haastattelu toimivat tutkimuksen materiaalina. Materiaalin analyysissa käytin sisällönanalyysin menetelmiä ja itsearviointivastauksia havainnollistettiin myös kvantitatiivisesti. Tutkimukseni mukaan lukioryhmällä on realistinen käsitys omista suullisista kommunikaatiotaidoistaan, si…
AI Ethics - Critical Reflections on Embedding Ethical Frameworks in AI Technology
2021
Embedding ethical frameworks in artificial intelligence (AI) technologies has been a popular topic for academic research for the past decade [1, 2, 3, 4, 5, 6, 7]. The approaches of the studies differ in how AI technology, ethics, role of technical artefacts and socio-technical aspects of AI are perceived. In addition, most studies define insufficiently what the connection between the process of embedding ethical frameworks to AI technology and the larger framework of AI ethics is. These deficiencies have caused that the concept of AI ethics and the construct of embedding ethical parameters into AI are used in an ambiguous, rather than in a complementary manner. One reason for the ambiguity…
Modelling of the air purification from volatile organic compounds in a trickle-bed bioreactor
2016
Badano proces oczyszczania powietrza ze styrenu, substancji zaliczanej do grupy lotnych związków organicznych (LZO), prowadzony w pilotowym bioreaktorze strużkowym (TBB). Ponieważ najważniejszym etapem procesu oczyszczania powietrza z LZO w bioreaktorze strużkowym jest biologiczna reakcja jego rozkładu, zatem, projektując proces, należy przede wszystkim starannie wyselekcjonować mikroorganizmy efektywnie rozkładające usuwane z powietrza zanieczyszczenie, określić warunki najkorzystniejsze dla ich wzrostu oraz wyznaczyć kinetykę reakcji. W wyniku testów porównawczych wyselekcjonowano szczep efektywnie wykorzystujący styren jako jedyne źródło węgla i energii. Był to, pochodzący z kolekcji VTT…

Flow-bed interactions analysis and application of automatic close range digital photogrammetric survey in a laboratory flume
2014
This paper reports on a laboratory study in which the automatic digital photogrammetric survey was applied to derive the high-resolution Digital Surface Model (DSM) of the bed topography, used for the flow-bed interactions analysis, in a large amplitude meandering laboratory flume. The analysis has been conducted with the aid of detailed data of three-dimensional flow field previously collected using the acoustic Doppler velocity profiler DOP2000. The applied surveying procedure has allowed the evaluation of the DSM with a resolution of ±0.5 mm. The detailed DSM has been compared with peculiar maps describing the flow velocity pattern (downstream and the crossstream flows) and the shear vel…
Hydro-mechanical analysis of volcanic ash slopes during rainfall
2016
Rainfall-induced landslides in volcanic ashes represent a major natural hazard in many regions around the world. Owing to their loose structure, volcanic ash slopes are prone to rainfall-induced landslides. The paper presents a continuum modelling approach for the analysis of wetting-induced instability phenomena at the onset of failure in loose volcanic ash slopes. A numerical simulation of a landslide-prone volcanic slope in Costa Rica is carried out with a two-dimensional hydro-mechanical finite-element slope model. A constitutive model based on the effective stress concept extended to partially saturated conditions is used to reproduce the volcanic ash hydro-mechanical behaviour. The m…
Electrochemical properties of graphite/nylon electrodes additively manufactured by laser powder bed fusion
2023
Nowadays, additive manufacturing, known as 3D printing, is vigorously employed at various enterprises due to the ability of industrial series production and customization in conjunction with geometry freedom. While, material design and fabrication of composite materials, meeting the desired architecture and properties, is another promising application of additive manufacturing. For instance, additive manufacturing of the material exhibiting electrochemical properties is beneficial for the development of freestanding electrodes that might be used in electrochemical energy storage systems. Herein, the graphite/nylon composite with a high carbon ratio of 30 wt% was produced by laser powder bed…
