Technology generation to dissemination: lessons learned from the tef improvement project
2018
Indigenous crops also known as orphan crops are key contributors to food security, which is becoming increasingly vulnerable with the current trend of population growth and climate change. They have the major advantage that they fit well into the general socio-economic and ecological context of developing world agriculture. However, most indigenous crops did not benefit from the Green Revolution, which dramatically increased the yield of major crops such as wheat and rice. Here, we describe the Tef Improvement Project, which employs both conventional- and molecular-breeding techniques to improve tef—an orphan crop important to the food security in the Horn of Africa, a region of the world w…
HorTILLUS—A Rich and Renewable Source of Induced Mutations for Forward/Reverse Genetics and Pre-breeding Programs in Barley (Hordeum vulgare L.)
2018
TILLING (Targeting Induced Local Lesions IN Genomes) is a strategy used for functional analysis of genes that combines the classical mutagenesis and a rapid, high-throughput identification of mutations within a gene of interest. TILLING has been initially developed as a discovery platform for functional genomics, but soon it has become a valuable tool in development of desired alleles for crop breeding, alternative to transgenic approach. Here we present the HorTILLUS ( Hordeum-TILLING-University of Silesia) population created for spring barley cultivar "Sebastian" after double-treatment of seeds with two chemical mutagens: sodium azide (NaN3) and N-methyl-N-nitrosourea (MNU). The populatio…
β-Amyrin Synthase1 Controls the Accumulation of the Major Saponins Present in Pea (Pisum sativum)
2021
Abstract The use of pulses as ingredients for the production of food products rich in plant proteins is increasing. However, protein fractions prepared from pea or other pulses contain significant amounts of saponins, glycosylated triterpenes that can impart an undesirable bitter taste when used as an ingredient in foodstuffs. In this article, we describe the identification and characterization of a gene involved in saponin biosynthesis during pea seed development, by screening mutants obtained from two Pisum sativum TILLING (Targeting Induced Local Lesions IN Genomes) populations in two different genetic backgrounds. The mutations studied are located in a gene designated PsBAS1 (β-amyrin s…
Over-ordering and food waste: The use of food delivery apps during a pandemic
2021
There is a paucity of research on the role of food delivery apps (FDAs) in food waste generation. This gap needs to be addressed since FDAs represent a fast-growing segment of the hospitality sector, which is already considered to be a key food waste generator globally. Even more critically, FDAs have become a prominent source of ordering food during the COVID-19 pandemic. In addition, the growing usage of FDAs warrants an improved understanding of the complexities of consumer behavior toward them, particularly during a health crisis. The present study addresses this need by examining the antecedents of FDA users’ food ordering behavior during the pandemic that can lead to food waste. The s…

Tid og rom for likestilling? : En kvalitativ studie av likestillingsarbeid sett i lys av barnehagens struktur
2017
Masteroppgave pedagogikk PED511 - Universitetet i Agder 2017 Background and purpose of the project The purpose of this study has been to investigate whether structural factors in kindergarten can affect gender equality in the children's group. Status reports from the kindergarten field show that gender equality is proving challenging in practiceand my research aims to look into what may be the reasons for this. Looking at the kindergarten structure, specifically time and space, I wanted to look at the role of time frames and different rooms in the gender equality issue. My research question is: What significance can the kindergarten's structural form have for the implementation of gender eq…
Kvinner på topp : hvem er de og hvordan har de kommet seg dit?
2006
Masteroppgave i offentlig politikk og ledelse 2006 - Høgskolen i Agder, Kristiansand På tross av lover og regler som sikrer likestilling har Norge et av Europas mest kjønnsdelte arbeidsmarkeder. Vi har blant Europas høyest utdannede og yrkesaktive kvinner, problemet er at gutter og jenter i Norge fremdeles tar svært tradisjonelle valg. Denne skjevheten gjelder spesielt blant toppledere og da særlig innenfor næringslivet. Jeg har i denne oppgaven valgt å fokusere på de kvinnene som faktisk har lykkes og i dag besitter topplederjobber i næringslivet. Mitt fokus er på olje- og energisektoren, som er svært mannsdominert. De siste 30 årene har man prøvd å komme med forklaringer på den lave kvinn…
Hvordan skapes rom for «omvendt deltakelse» i bærekraftig lokal samfunnsutvikling – aksjonsforskningens roller og bevegelser
2021
Det er økende oppmerksomhet på potensialer for borgeres engasjement i bærekraftig omstilling og lokaliseringen av FNs bærekraftsmål. Flere forsknings- og policyrapporter etterlyser bedre forståelse for hvordan bærekraft kan «oversettes» og implementeres i lokal planlegging og handling. Bærekraftig samfunnsomstilling krever bedre forståelser for hvordan offentlige/kommunale systemer kan samarbeide med borgerinitiativer – samtidig som de lokale initiativene bevarer selvstendighet og lokal forankring. I denne artikkelen tar vi utgangspunkt i en aksjonsforskningsprosess med borgerinitiativer i Oslo og ByKuben, Oslo kommunes senter for byøkologi. Vi utforsker hvordan det kan skapes rom for delta…
Når preposisjonar erstattar kasus : om preposisjonsobjekt (objektsadverbial) frå norrønt til moderne norsk
2006
Masteroppgave i Nordisk språk og litteratur 2006 - Høgskolen i Agder, Kristiansand Dette arbeidet har to hovuddelar. Den første delen er ei valensundersøking. Formålet med denne undersøkinga er å finne ut kva for valens verb som i moderne norsk krev preposisjonsobjekt, hadde på det norrøne språksteget. Den andre hovuddelen er ein analyse av preposisjonsobjekt i moderne norsk, med grunnlag i det teoretiske rammeverket i arbeidet, Lexicase Dependency Grammar (Starosta 1988). Sentrale prinsipp i Lexicase Dependency Grammar (LCDG) blir presenterte i kap. 2. I dette kapittel blir også metodiske spørsmål i samband med valensundersøkinga diskuterte, og korpusa som dannar grunnlag for undersøkingan…
Feedbacksløyfer i teater for svært unge tilskuere. Et bidrag til en performativ teori og analyse
2010
Feedback loops in theatre for very young audiences contributes to a performative theatre theory and performance analysis. Moreover, the dissertation explores an underexposed field in theatre studies: theatre for children under three years of age – sometimes as young as six months old. My starting point has been the presumption that theatre artists receive productive challenges from such young audiences, and that aesthetic strategies in performances can be read as answers to such challenges. The study focuses on the significance of very young children’s pronounced presence as theatre audiences, in what I call a non-discreet audience style. The methodological aim has been to develop a mode of…
