    Review on Mechanistic Effect Models Used in Ecological Risk Assessment of Pesticides According to the European Food Safety Authority Guidance2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In ecological risk assessment, mechanistic effect models (MEMs) are thought to overcome the limitation of standard laboratory single species test by accurately extrapolating the models to population-level. This review introduces the basic theory of MEMs-dynamic energy budget theory which can connect with toxicokinetic/ toxicodynamic models to describe the interaction of toxicants and organisms. This review summarizes some typical MEMs which simulate different scenarios, pesticides and species, and compared their modelling performance according to the guidance on good effect models of European Food Safety Authority, in order to judge if it is accounting for all modelling steps. In addition, a summary of the linkage of MEMs in pesticides ecological risk assessment have been discussed, especially evaluating the linkage results of ‘MODELINK’ workshop. However, there is no genuine application of MEMs in pesticides ecological risk assessment in real world today, because there is no validated model built with acceptable predictive power to motivate the ecological assessors or shareholders to use effect models confidently. Therefore, there is still a long way to develop an effect model which is valid enough and has strong prediction power.

    Identifying influencers on Instagram: Important factors to consider when identifying influencers to use for sponsorships and collaborations2018Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The growth of the Internet and social media has led to companies considering the use of influencers in sponsorships and collaborations on Instagram. The subject has been problematized and the gap found is a need for a framework combining different factors when identifying influencers, which resulted in the following research question; From both a company- and consumer perspective, which factors are important to take into account when identifying an influencer for sponsorships and collaborations on Instagram?

    The purpose is first to identify and incorporate important factors discussed in previous research into a proposed framework, which aims to be used when identifying influencers to sponsor on Instagram. Second, after conducting the empirical research, the framework is extended depending on the new collected information. Background theories and concepts that lay the foundation to influencer marketing are presented. Also, previous frameworks regarding identification of influencers are introduced. The theoretical framework chapter is concluded with a proposed framework alongside introducing the factors.

    Abductive research strategy is used as well as a method triangulation, using both a qualitative and a quantitative approach. The study is an explorative research due to conducting both a documentary analysis and a questionnaire. The factors studied have shown to be of different importance for companies and consumers.

    The findings indicate that there are multiple types of influencers. The Updated influencer identification model consists of seven important factors; ideal, trust, popularity, productivity, managing sponsorships and collaborations, information content and visual aspect.

    Hur och på vilket sätt kopplar lärare samman No-undervisningen med elevernas vardag?2018In: FND 2018: Forskning i naturvetenskapernas didaktik: Samhällsfrågor i naturvetenskaplig undervisning, 2018, p. 12-12Conference paper (Refereed)
    Abstract [sv]

    Upplevelser och händelser som sker i elevernas vardag kan ibland problematiseras utifrån en naturvetenskaplig kontext. I denna studie har vi analyserat vi hur lärare,som undervisar elever i årskurs nio, använder sig av elevernas vardagserfarenheter då de undervisar, analysen bygger påKamberelis och Wehunt (2012) definition av hybrid diskurs-praxis. Analysen fokuseraspå den första inledande delen av lektionen, då läraren oftast är den främsta aktören i undervisningen. Denövergripande anledningentill att göra dessa analyser är indikationerna i PISA som visar att de svenska eleverna upplever den naturvetenskapliga undervisningen relevant men ointressant. I detta sammanhang blir det därför relevant att undersöka hur lärare talat om naturvetenskap i relation till elevernas vardagserfarenheter. Studien gjordes vid 6 olika skolor där totalt 44 lektioner spelades, dessa lektioners inledningar analyserades. 67 situationer detekterades och kategoriserades i tre övergripande grupper; Vardaglig kontext, Skolkontext och Språklig kontext. Vardagligkontext delades sedan i underkategorier ett exempel är: underkategorin, förklarande berättelser (12 situationer), har vi samlat de situationer där läraren, till synes spontant, hittar på berättelser för att kontextualisera naturvetenskapen. Noterbart är att inga längre berättelser förekom utan samtliga historier var korta kontextualiserande berättelser. Skolkontext hade inga underkategorier utan samtliga situationer referenser till andra skolämnen innebär att läraren relaterar till andra skolämnen genom att beskriva ämnesinnehållet som en del av en större enhet och skapar därmed en hybriditet mellan de olika skolämnena. Vid sex tillfällen gjordes sådana kopplingar till andra ämnen. Språkligkontext har tre underkategorier var av en är, Sammankopplar naturvetenskapliga ord med vardagsord, i denna underkategoriåterfinns främst på en av skolorna och då i ämnet kemi, när eleverna arbetade med ämnesområdet organiska syror. Genom att namnge de organiska syrorna med både vetenskapliga och vardagligt språk ger läraren eleverna möjligheter att se sambandet mellan det kemins ordval, askorbinsyra, och det ordval som görs i vardagen, C-vitamin.
