Dewey’s Conceptualization of the Public as Polity Contextualized: The Struggle for Democratic Control over Natural Resources and Technology

This article explores John Dewey’s conceptualization of the public as polity in his lecture notes from 1928. Dewey’s conceptualization suggests an account of the democratic legitimacy of public regulation of economic activities by focusing on polity members’ mutual interest. Contextualized through Dewey’s involvement in practical politics the article specifies the conceptualization by a policy focus on natural resources and technology, and explores and discusses it through two issues for democratic control over policy development: centralization of power in federal government; and the failure to understand, predict and control consequences of technology. Finally, exploring its relevance in a context of economic globalization the article rearticulates the conceptualization in terms of transnational relations and solidarities, using the transnational peasant organization La Via Campesina as an example.acceptedVersio

Airborne Field Measurements and Model Simulations of Boundary Layer Properties over the Iceland Sea

The spatial and temporal distributions of a cold air outbreak (CAO) event over the Iceland- and southern Greenland Seas have been investigated during the IcelandGreenland Seas project (IGP) in February and March 2018. This area is arguably the least studied region of the North Atlantic sub-polar seas, and several observing platforms were therefore utilized in investigating the critical processes in the region. The focus of this study is on increasing the understanding of how the thermodynamic properties within the atmospheric boundary layer develop during a CAO. This is done by analysing observational data from a research aircraft and radiosondes. A distinct boundary layer deepening was observed over the marginal ice zone (MIZ), in the office direction, as the ocean transferred large amounts of heat and moisture to the atmosphere. In addition to providing in-situ measurements over the Iceland-Greenland Seas, the observational data are compared to the high-resolution regional COSMO_iso model in order to determine an optimal model setup for accurate simulations of the atmospheric water cycle. The accuracies of the model forecasts were observed to increase with decreasing lead time and finer resolution. A simulation with relatively long spin up time included large biases of surface temperature and humidity due to the development of an instability in the study area. These errors are reduced for the simulations with shorter spin-up time, at which a combination of fine resolution and 9-18 hours spin-up time is deemed optimal.Masteroppgave i meteorologi og oseanografiGEOF399MAMN-GEO

Life Cycle Cost Analysis of a Floating Wind Farm Located in the Norwegian Sea

This thesis aims to investigate the levelized cost of energy of an offshore floating wind farm, as well as evaluate its financial feasibility. Thus, the research question is as follows: How to estimate the life cycle costs of a floating wind farm off the coast of Norway? The investigated wind farm is located off the coast of Norway, more specifically in the Troll field area west of Bergen. This area has a water depth of 325 m and a distance to shore of 65 km. The wind farm is set to consist of 50 wind turbines and has a lifespan of 25 years. The OC4 Deepwind semisubmersible floater developed by the National Renewable Energy Laboratory, complemented with a 15 MW turbine, is used as the research model. To find the capital expenditures of the planned wind farm, the Offshore Renewables Balance-of-system and Installation Tool is used, while the operational expenditures are calculated based on the theoretical energy output. The total levelized cost of energy of the wind farm is calculated to be 100.69 $/MWh. Capital expenditure is the most prominent cost and constitutes 63.1 expenditures constitute the remaining 36.9 lifespan, capacity factor, and project discount rate are the factors with the most potential to influence the levelized cost of energy. The financial calculations show that the wind farm is not economically feasible as it has a computed net present value of negative$ 561 900 000. Finally, novel offshore wind energy solutions involving the utilization of shared substructures and mooring lines have been studied, and the findings suggest the possibility of a diminished levelized cost of energy

Stemmen til den uskyldige tredjepart. Barns erfaringer knyttet til foreldrenes skilsmisse

Innledning med bakgrunn: Over 17 000 barn i Norge opplevde at foreldrene ble skilt eller separert i 2021. Barns egne erfaringer rundt skilsmisse blir preget av aggressive, engstelige og depressive tanker og de føler seg ofte ikke hørt i spørsmål som omhandler dem. Mange barn beskriver tiden rundt foreldrenes skilsmisse som vanskelig, og etterlyser ressurspersoner som ser og følger dem over tid. Hensikten med denne litteraturgjennomgangen er å få innsikt i barns erfaringer knyttet til foreldrenes skilsmisse. Innsikt i barns erfaringer kan danne grunnlag for økt bevissthet og kunnskap hos helsesykepleier i deres arbeid med skilsmissebarn. Metode: Det ble gjennomført et systematisk litteratursøk i databasene CINAHL, PsycINFO, SveMed+, og MEDLINE i mars 2022. Tre artikler ble inkludert i litteraturgjennomgangen. Resultat: Barns erfaringer knyttet til skilsmisse er varierende, og en skilsmisse har ikke en utelukkende negativ konsekvens på deres hverdag. Forskning viser likevel at støy og ustabilitet knyttet til skilsmisse kan gi dem en mindre gunstig barndom. I denne litteraturgjennomgangen er barns forskjellige erfaringer presentert i tre kategorier: erfaringer knyttet til relasjoner, erfaringer knyttet til tilpasning, og erfaringer når det gjelder deres egen rolle i skilsmissen. Konklusjon: Å være skilsmissebarn kan heve stressnivået i et barns hverdag, og trygge relasjoner, både til familie og ressurspersoner utenfor hjemmet, er viktig for å ha en følelse av stabilitet og forutsigbarhet. Innsikt i barns erfaringer kan gjøre helsesykepleier bedre rustet til å være en viktig og støttende tredjeperson for skilsmissebarn

Dimensjonering av betongbruer i bruksgrensetilstand - Evaluering av beregningsgrunnlaget i Eurokode-systemet og norsk praksis

Bruksgrensedimensjonering er et viktig tema i BIA-prosjektet «DACS - Durability advanced concrete structures» (Kværner, Multiconsult, SVV). I den sammenheng er det blitt utført beregninger i bruksgrensetilstanden av en slakkarmert bru i betong i denne oppgaven. Brua var utført som en massiv tre spenns platebru, med en total lengde på 38,3 m. Brua hadde et hovedspenn på 16,3 m og var understøttet av to betongsøyler i hver akse, samt to sidespenn på 11 m. Formålet med denne oppgaven er å evaluere beregningsgrunnlaget for betongkonstruksjoner i dagens eurokoderegelverk i bruksgrensetilstanden. Evalueringen blir gjort ved å sammenligne oppførsel og målinger fra et be-lastningsforsøk på Smedstua bru, med beregninger etter nåtidens regelverk. I tillegg er det utført et litteraturstudium om bruksgrensedimensjonering av betongkonstruksjoner, og om skallteori for armerte betongelementer. Modellering og analyse ble utført i elementprogrammet Abaqus/CAE. Det ble benyttet skallelementer i modellen. Skivekreftene fra Abaqusmodel-len ble analysert med skallprogrammet BABE v1.0. På grunn av avvik i skallresultatene ble det valgt å gå videre med spenningene som ble bereg-net i Mathcad i henhold til lærebokmaterialet til Sørensen i stedet. Spenningsbegrensningen i EK2 konkluderte med at tverrsnittet vil risse opp på strekksiden i hovedfeltet og over søylene. Resultatet samsvarte med observasjonene i forsøket. Momentet fra egenvekten alene var 345 kNm i hovedfeltet, mens tverrsnittet vil risse opp ved 283 kNm i samme snitt iføl-ge beregningene. Spenningsbegrensningene ble oppfylt for samtlige snitt, sett bort ifra trykkspenningen i søylesnittet. Rissavstand- og rissviddebe-grensningene var tilfredsstilt for samtlige snitt, samt minimums armerings-mengde for rissbegrensning. Sammenligningen mellom nedbøyningsresulta-tene i forsøket og skallmodellen ga tilfredsstillende resultater. Jevnt over lå de opptredende tøyningene i forsøket nærmere beregnet stadium I-stivhet enn stadium II-stivhet, tross et opprisset tverrsnitt. Basert på analysen oppførte brua seg stivere under forsøket enn beregningene hentydet

Life cycle cost analysis of a floating wind farm in the Norwegian Sea

The offshore wind energy industry has witnessed rapid growth in the past decade. Still, there is a lack of commercial floating wind projects due to the relatively high development costs and other factors. To facilitate the holistic evaluation of floating wind farms in Norway, this article investigates the levelized cost of energy of a floating offshore wind farm and its economic feasibility. The Troll field west of Bergen, Norway, is assumed to be the target offshore site, and a farm size of 50 wind turbines with a lifespan of 25 years are considered. Each floating wind turbine has a 15-megawatt turbine mounted on a semi-submersible floater. Based on detailed analysis, the levelized cost of energy of the wind farm is estimated to be approximately 100.7 $/MWh. The capital expenditure is the most prominent cost and constitutes 63.1% of the total cost, and the operational expenditure constitutes the remaining 36.9%. Further, sensitivity analyses show the influence of the lifespan, capacity factor, and project discount rate on the levelized cost of energy. The present study contributes to techno-economic evaluation of floating wind projects at an early phase.publishedVersio
