    Jesu mor – från Kana till korset: En hermeneutisk analys av bibelkommentarer till Johannesevangeliet2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna uppsats söker besvara frågan ”Hur tolkas Jesu mor i nutida bibelkommentarer till Johannesevangeliet, utifrån de exegetiska forskningsfälten historicitet, litterärkritik och teologi?”. Syftet är att bidra till ett kritiskt och reflekterande samtal kring den exegetiska bibelkommentaren som genre, och i synnerhet bidra till en ökad förståelse av hur nutida exegetiska bibelkommentarer behandlar en teologiskt omstridd biblisk gestalt. Uppsatsen utgår från en teoretisk utgångspunkt som innebär att exegetik inte kan bedrivas opåverkad av exegetens egna föreställningar, varför skillnader mellan olika tolkningar är att förvänta. Uppsatsen har en kvalitativ, hermeneutisk metodansats. Det metodologiska tillvägagångssättet är att med hjälp av problemformuleringen och arbetsfrågorna analysera och diskutera hur Jesu moders historiska, litterära och teologiska roll i bibeltexterna Joh 2:1-11 och 19:25-27 tolkas i nio utvalda exegetiska kommentarer till Johannesevangeliet.I kapitel 1 introduceras teori, metod, avgränsningar, begrepp, angränsande forskning, material och disposition. I kapitel 2 presenteras de grekiska texterna till de aktuella perikoperna 2:1-11 och 19:25-27, som ett stöd för läsaren. I kapitel 3 analyseras de nio bibelkommentarerna i tur och ordning enligt arbetsfrågorna. I kapitel 4 sätts bibelkommentarernas respektive tolkningar i relation till varandra; och en diskussion kring likheter, skillnader och mönster förs. I samma kapitel presenteras en sammanfattande diskussion, uppsatsens slutsatser och förslag till framtida forskning.Uppsatsens slutsatser är (1) att Jesu mor som historisk gestalt är indirekt föremål för diskussion, genom en mer övergripande diskussion om Johannesevangeliet som ögonvittnesskildring eller ej, (2) att Jesu mor i allmänhet framstår som en rund, statisk (se 1.3 Teori och metod för en förklaring av dessa begrepp) karaktär i de analyserade kommentarerna, och (3) att Jesu mor av de flesta anses som en viktig teologisk gestalt, framförallt som en del i en uppfattad johanneisk teologi om en familj av troende som instiftas av Jesus; en ståndpunkt som dock väcker debatt och möter motstånd

    Ett tillfälle för avslappning?: En enkätundersökning om svenska gymnasieelevers syn på meditation i klassrummet2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Introduction: What would a Swedish upper secondary student say if suddenly, meditation was introduced as an optional addition to his or her schedule. Would they be optimistic and see it as an opportunity for relaxation in their hectic day? Or would they be of the opinion that meditation is a religious practice and should not be allowed in a secular school? Perhaps they would think neither, instead holding a more neutral opinion? This was the central question for this questionnaire study. It was asked based on the reaction yoga received when it was introduced in a Swedish school, as some adults saw it as a religious practice. Later it was decided by the School Inspection that it was to be allowed, as attendance was completely voluntary.Method: The questionnaire in this study used four closed questions to get information on the attitude of upper secondary students towards meditation in schools, their interest in attending the hypothetic meditation and the most frequently used arguments for and against it. The questionnaire was modelled after Alan Brymans book Social research methods. After the questionnaire was finalized, it was sent out to mentors of third year students of several high schools in Västerbotten County. The goal was to get 100 responses from upper secondary school students, in the end 78 responses were obtained. The results of the questionnaire were presented in circle and bar graphs.Results: The gathered information showed that a majority of the surveyed upper secondary students had a positive attitude towards meditation in their schools. Among the most frequently used arguments pro and against the meditation, the most frequent argument for the inclusion of meditation was that it would be an opportunity for relaxation. Of the arguments against the inclusion of meditation the most frequent was that it would take up unnecessary space in their schedule.Conclusion: Through the information gathered with the questionnaire we can see a theme of positive attitude from the students. A clear majority of them are either interested in trying meditation, sees it as a useful tool, or simply has a positive view of it while perhaps being less interested of trying it themselves.

    Fågelfångstanläggningar: Sockensamer & skogsfågelfångst i Gävleborg och Västernorrland under historisk tid2018Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This paper seeks to provide a better understanding of the supposed connection between Parish Sami and the little researched stone remnants of grouse trapping, i.e. bird mazes, that show a spatial concentration to Västernorrland and Gävleborg counties - by using spatial analysis, historical-ethnographical analogies, folklore studies and two case studies. The results are contradicting; the spatial analysis shows no or little signs of a connection between remains of Sami type and place names indicating Sami presence. The analogies show a likeness between methods where sticks and branches were used instead of stones to create the fences which lead the birds to the snare-traps. However, these methods were used by both Swedish farmers and Sami. There are several folklore records that connect Sami and the bird mazes, and one tells of how the Sami taught the parish inhabitants the method. The case studies show an apparent spatial connection between bird mazes and a Parish Sami home and a nomadic Forest Sami complex. Nomadic Forest Sami in the region have been shown to be the ancestors of Parish Sami. Based on these results, the author proposes that the bird maze method was first used by Forest Sami and later used by their descendants Parish Sami, but somewhere along the way the method was taught to or picked up by Swedish farmers. In any case, this study might be used as a jumping off point for the further work and research into the physical remains of Sami in the region that are well needed, in particular the Parish Sami, but also bird mazes.

    Själens skakningar: Livskraft, kropp och känslor i C.W. Hufelands Konsten at lefwa länge2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay will examine the Swedish edition of the German treatise, Makrobitoik oder die Kunst das Leben zu verlängern (1796), which was published in Sweden in 1798. The treatise became immensely popular throughout Europe after it was published and its author, C. W. Hufeland became known for his macrobiotic; that is the art of prolonging one’s lifespan.

    The Swedish edition, Konsten at lefwa länge, will be examined from a medical history per-spective with the intention to analyze the connections between vitalism, emotions and the body. The analysis is primarily an exploration into the depiction of emotions, their connec-tions to the body and to medicine but will also analyze the treatise’s vitalist theory. The essay will also examine the portrayed difference between the sexes. The aim of the analysis is to further the knowledge of the history of the body, medicine and of emotions from an eight-eenth century scientific viewpoint.

    The analysis establishes the importance of the vitalist theory for the treatise’s view on the body and on emotions. The body was largely controlled and in symbiosis with a lifeforce that originated from nature itself. It was very important to properly manage the lifeforce and doing so also meant controlling the emotions. An emotional outburst was believed very dangerous and especially feelings of melancholia, hypochondria and envy could seriously affect one’s health. Possible outcomes of these unhealthy emotions were the drainage of the body’s lifeforce which then affected other functions, such as the digestion, the cardiac cycle and the nervous system. This could ultimately result in the body’s decay and finally death.

    It is also established that women were more likely than men to suffer the dangers of emo-tions. Since their lifeforces and bodies were frailer they were also more prone to suffer from hypochondria and emotional affliction. The treatise also explains that the male lifeforce was in some ways preferable to the female lifeforce which made men more durable.

    Though just like some emotions were deemed unhealthy and dangerous there were also emotions that were vital to a long life. Love, happiness and tranquility for instance were im-portant components for the body’s health though self-control and a rational use of one’s emo-tions were deemed most important.

    Tittar du på mig?: En kvantitativ studie om videomarknadsföring på Instagram2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Sociala medier är ett vanligt förekommande fenomen som används av allt fler människor världen över. På sociala medier ges både företag och privata användare möjlighet att publicera videoinnehåll. I linje med att video på sociala medier växt fram, har möjligheter att använda video i marknadsföringssyfte utvecklats. Det har resulterat i att allt fler företag och marknadsförare insett fördelen med att inkludera video som en aspekt i marknadsföringsstrategier.

    Det har identifierats ett teoretiskt gap inom forskning som behandlar vilka attribut som bör inkluderas i en video för att fånga en konsuments intresse och främja videodelning. Syftet med denna studie är således att få kunskap kring attribut som är av betydelse vid utformning av videomarknadsföring på sociala medier och om dessa attribut är av betydelse för huruvida en video sprids genom videodelning. Författarna ämnar dessutom undersöka om video på sociala medier kan ha en eventuell påverkan på tittarens köpintention. Studien ämnar således besvara följande forskningsfråga:

    Vilka attribut bör inkluderas i videomarknadsföring på sociala medier för att attrahera tittare och generera spridning?

    Studien har utförts utifrån en kvantitativ metod och studieobjektet är användare Instagram. I samband med att Instagram introducerade möjligheten att publicera video, har videomarknasföring blivit allt vanligare och mer framträdande i kanalen. Via videomarknadsföring på Instagram har företag och marknadsförare potential att nå ut till en stor publik. Utifrån syftet och den forskningsfråga som författarna ämnar besvara har teori gällande native advertising, viral marknadsföring, videodelning, elektronisk word- of-mouth (eWOM), AIDA-modellen samt attribut inom video inkluderats i studiens teoretiska referensram.

    Den empiriska data som återfinns i studien har samlats in genom en webbenkät och den urvalsstrategi som använts är snöbollsurval. Statistiska tester i from av chitvå-test samt korrelationstest har genomförts för att härleda samband mellan olika variabler. Cronbach’s Alpha har genomförts för att styrka studiens inre reliabilitet. Utifrån den data som samlats in och utifrån de statistiska tester som genomförts har det konstaterats att attributen underhållning, engagemang och utformning bör inkluderas i videomarknadsföring för att attrahera tittare och generera spridning.

    Studien bidrar med en teoretisk modell som revideras utifrån studiens resultat. Modellen bidrar med teorier och attribut som är av relevans att beakta vid utformning av videomarknadsföring på sociala medier av såväl företag som marknadsförare.

    Utdelningar och Återköp: - Hur har distributionen av finansiella medel utvecklats samt vad förklarar företagens beslut om utbetalningspolicy?2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Trots att ämnet utbetalningspolicy har studerats i över ett halvt sekel anses det ändå av forskare vara ett pågående pussel. Utbetalningspolicyn i publikt handlade företag innefattar olika val och interna riktlinjer vad gäller att distribuera finansiella medel till aktieägarna. För att öka värdet på investerarnas kapital gör företagen en årlig avvägning mellan att betala ut finansiella medel till aktieägarna och att kvarhålla dessa i företaget för att återinvestera i nya projekt. Efter denna avvägning finns två huvudsakliga sätt att betala ut återstående medel till aktieägarna, det vill säga kontant utdelning och återköp av egna aktier.

     

    Studiens teoretiska referensram bygger på kontanta utdelningar som den traditionella formen av utbetalning till aktieägarna. Sedan återköp av egna aktier i USA tog fart under 1980-talet har dock senare forskning visat att utdelningar minskat och att återköp tagit över som distributionsmetod. Detta fenomen benämns substitutionshypotesen och innebär att företag i större utsträckning köper tillbaka egna aktier med finansiella medel som annars hade använts för att öka utdelningarna.

     

    Vilken form av utbetalning som företagens investerare prefererar kan dock vara olika. För att optimera sina investeringar är det av vikt för dem att förstå vad som påverkar företagens beslut om utdelningar respektive återköp. Syftet med den här studien var därför att undersöka ämnet utbetalningspolicy bland svenska företag inom segmentet large cap. Utifrån detta formulerades följande frågeställning:

     

    Hur har utbetalningspolicyn bland svenska large cap företag utvecklats samt vad förklarar deras beslut att distribuera finansiella medel genom utdelningar respektive återköp av egna aktier?

     

    För att besvara denna fråga utformades hypoteser för att testa om det skett en signifikant förändring i företagens utbetalningspolicy mellan åren 2007–2016. Studien har även testat om det finns ett signifikant samband mellan ett företags utbetalningspolicy och de inom tidigare forskning mest frekvent förklarande variablerna årsresultat, lönsamhet, storlek samt historiska utdelningar/återköp.

     

    Resultatet visar att det inte skett någon större förändring bland företagens utdelningar över den valda tioårsperioden. Däremot upptäcktes att återköpen av egna aktier signifikant minskat vilket motsäger vad tidigare teorier sagt om att återköp som utbetalningsform tagit över. Vidare konstaterades att de variabler som har en påverkan på företagens beslut om utdelningar respektive återköp är dess historiska nivåer. Resultatet från denna studie bidrar således till att investerarna får en vidare förståelse för vad som påverkar företagen i deras beslut om utdelningar respektive återköp för att i största mån välja att investera i företag som optimerar investeringarna baserat på deras egna preferenser.

    Lite snack och mycket verkstad: En studie om vilka verktyg som kan hjälpa restauranger att bli mer hållbara2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Klimatkrisen är en svår utmaning som alla på planeten tillsammans måste försöka att lösa. En av de branscher som idag har en stor negativ påverkan på klimatet är restaurangbranschen där verksamheterna främst arbetar med livsmedel, vilket har påvisats bidra till en stor mängd växthusgasutsläpp. Restaurangbranschens verksamheter behöver därmed ställa om till att bli mer hållbara när det kommer till såväl ekonomisk som social och ekologisk hållbarhet. Det finns en efterfrågan från restauranger som vill ha hjälp med att ställa om sina verksamheter till att bli mer hållbara, då de har svårt att veta vart och hur de påbörjar detta arbete. En genomlysning av aktuell forskning har visat på att det finns ett behov av att ta fram konkreta verktyg som underlättar hållbarhetsarbetet för verksamheter.Denna studie har därför haft som avsikt att besvara problemformuleringen:Vilka verktyg är praktiskt tillämpbara för att uppnå en hållbar restaurangverksamhet?Vi författare till denna studie valde att genomföra en explorativ studie då detta ansågs ge bättre möjligheter till att skapa en djupare förståelse inom vårt valda problemområde. För att ta reda på vilka verktyg som kan anses vara lämpliga för restaurangverksamheter har teorier, kopplat till förutsättningar och hinder, presenterats för att skapa en förståelse för vad som kan påverka valet av lämpliga hållbarhetshanteringsverktyg. De verktyg som har valts ut till denna studie är: hållbarhetsredovisningar, livscykelanalys, kvalitetsledningssystem, nätverk, utbildning samt grön nudging.Semi-strukturerade intervjuer genomfördes där respondenternas svar tyder på att det finns förutsättningar inom restaurangbranschen för att arbeta med hållbarhet. Intervjuerna visade även på att det finns hinder för detta, främst i form av tid, pengar och snäv kunskap om hållbarhet. Som komplement till intervjuerna framtogs en enkät för att undersöka respondenternas attityd till de utvalda verktygen. Det som anses vara det bäst lämpade verktyget för restauranger att implementera är utbildning, då kunskap är grundläggande för ett framgångsrikt hållbarhetsarbete. Även verktygen nätverk och grön nudging har visat sig vara väl lämpade för restaurangverksamheter.Studien har även bidragit med framtagandet av en modell, vars syfte är att bidra med struktur till studien, som visar de olika steg som restauranger bör genomgå innan implementering av ett verktyg på den operativa nivån av verksamheten. Vidare visas även vilka förutsättningar som är väsentliga och vilka hinder som kan uppstå, för att kunna arbeta med hållbarhet i verksamheten. De verktyg som anses vara mest praktiskt tillämpbara för restauranger är också de verktyg som har bäst förutsättningar och minst hinder för att kunna implementeras i verksamheternas dagliga drift.

    Skulle en finansiell förändring påverka bolånetagare i Sverige?2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Finansmarknaden har visat sig ha stor effekt på länders ekonomier. I den globaliserade värld vi idag lever i innebär det att en kris i ett land kan sprida sig till resten av världen. Detta var vad som hände under finanskrisen 2008–2009. Då uppstod en kris i USA med grund i ett flertal faktorer. Bidragande faktorer var bland annat en generös utlåningspolitik och en tickande bostadsbubbla.

    Sveriges bostadsmarknad har under en lång tid präglats av stigande bostadspriser och historiskt låga räntor. Detta har, tillsammans med amorteringskravet, skapat spekulationer kring ökade räntor och fallande bostadspriser. Trots spekulationer och förändringar på marknaden, finner vi ingen tydlig förklaring till hur dessa händelser skulle påverka bolånetagare i Sverige. Några menar att bolånetagare i Sverige är väl rustade för en finansiell förändring, medan några hävdar att det skulle påverka vissa bolånetagare i högre utsträckning.

    Studiens teoretiska grund är huvudsakligen tre teorier, dessa är flockbeteende (herd behavior), finansiell förståelse (financial literacy) samt asymmetrisk information (asymmetric information). Studiens syfte uppfylldes genom att vi med stöd från dessa teorier undersökte hur bolånehandläggare i jämförelse med andra låntagare i Sverige påverkas vid finansiella förändringar.

    Studiens hypoteser testades utifrån insamlad primärdata från respektive grupp. Datat analyserades sedan genom MWU-tester, Multipla regressioner samt Chi2-tester. Vi finner utifrån resultatet att bolånehandläggarna är den grupp som skulle kunna hantera en finansiell förändring i form av en räntehöjning bättre. Det påvisades dock ingen signifikant skillnad mellan hur en bolånehandläggare, i jämförelse med andra låntagare skulle påverkas vid ett prisfall på bostadsmarknaden. Det kunde dock påträffas stöd för att bolånetagare generellt är högt belånade i Sverige. Vilket kan leda till att de skulle påverkas om ett framtida fall i bostadspriserna sker. Skillnaden vid påverkan av en räntehöjning mellan grupperna kunde förklaras med stöd från studiens teorier. Det visade sig att bolånehandläggarna är den grupp som inte följer flockbeteendet i samma utsträckning, har en bättre finansiell förståelse samt ett informationsövertag gentemot andra låntagare.

    Dessa resultat ger en insikt i vad som avgör hur bolånetagare i Sverige påverkas av finansiella förändringar på bostadsmarknaden. Det redogörs även för vad bolånetagarna kan göra för att minska denna påverkan. Då studien jämför två grupper av bolånetagare visar resultatet tydligt vad som skiljer grupperna åt i beteende, finansiell kunskap samt informationsinhämtning. Dessa resultat är därför viktiga i vägledande syfte för bolånetagare i Sverige.

    Hållbar kreditgivning: En kvalitativ studie om hur banker bör agera pionjärer för hållbar utveckling2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vår omvärld förändras i snabb takt och hållbarhetsfrågorna blir allt viktigare i en värld där klimatförändringar och sociala problem får allt större fokus i samhället. Bankbranschen är en stor del av samhället med bland annat en utlåning som motsvarar nästan hela Sveriges BNP vilket gör att bankerna har en stor indirekt påverkan. Branschen har på senare år fått ett bredare hållbarhetsperspektiv gällande fondsidan samt vid kreditgivning. Tidigare forskning finns på ett djupare plan för just fondsidan menkreditsidandäremottycks vara eftersatt där forskning inte alls existerar i samma utsträckning. FI genomförde år 2015 en studie i ämnet där de i slutsatsen efterfrågade en större transparens från bankerna kring hållbarheten vid kreditgivning. Med utgångspunkt i denna undersökning införde Svenska Bankföreningen riktlinjer kring detta och hur bankerna skulle arbeta för att skapa större transparens kring området. Dessa två studier och riktlinjer har sedermera använts som inspiration för att forma vår studie. Vår studie undersöker hur bankerna arbetar med hållbarhet i kreditgivningsprocessen samt huruvida detta skiljer sig bankerna emellan. Syftet med studien är att undersöka hur bankerna definierar hållbarhet och hur det integreras i deras kreditanalys. Vidare undersöker vi vilka risker som är förknippat med hållbarhet och hur detta påverkar bankens risktagande samt hur de har möjlighet att ha en indirekt påverkan på samhället. Med hjälp av fyra stycken semi-strukturerade intervjuer med respondenter som arbetar i roller som kreditanalytiker eller liknande har vi sedermera besvarat syftet med studien. I studien har vi använt oss av tre huvudsakliga teorier som bas, samt tre stycken mer specifika teorier för att fördjupa den teoretiska aspekten avstudienytterligare. De teorier som har valts är CAPM för att se relationen mellan risk och avkastning, Triple Bottom Line; för att undersöka huruvida det enbart är det ekonomiska resultatet som spelar roll för företagen samt Kuznets Curve för att undersöka relationen mellan miljöförstöring och ekonomisk tillväxt. Frågeställningen för studien lyder: Hur arbetar banker med att analysera hållbarhetsaspekter och risker kring dessa vid kreditgivning till stora företag?Samt i vilken utsträckning kan banker bidra till hållbar samhällsutveckling genom att ställa krav på kredittagarens hållbarhetsarbete?Vår studie visar hur bankerna har kommit olika långt i sitt arbete med detta, där vissa har hållbarhetsanalysen som en separat del och vissa har den integrerad i analysen. Gemensamt för samtliga banker är att de tar frågan på stort allvar och attde ser hållbarhet som en delav den totala riskanalysen. Resultatet visar även hur samtliga banker anser att de kan påverka och har en stor del i hur hållbarhetsfrågan kan drivas framåt i samhället.

    Motivation bland anställda  : En studie om balansen mellan handlingsfrihet och styrning och dess inverkan på anställdas motivation inom hotell- och restaurangbranschen2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Ett förekommande problem hos individer på arbetsplatser är motivationsbrist, till den grad att anställda inte längre vill gå till arbetet som i sin tur kan resultera i att de väljer att säga upp sig. Detta påverkar såväl de anställda och företagen, som ekonomin och folkhälsan i samhället. Problematiken med hög personalomsättning är betydande inom den svenska hotell- och restaurangbranschen där få anställda väljer att stanna under en längre tid. Det finns diverse potentiella orsaker till den höga personalomsättningen i hotell- och restaurangbranschen, en av dessa potentiella faktorer kan vara motivationsbrist bland anställda. Därav kommer studiens fokusområde att vara anställdas motivation på arbetet.

     

    Efter en litteraturundersökning av tidigare forskning inom ämnesområdet, har det konstaterats att en grundläggande faktor till individens motivation är handlingsfrihet. Detta då studier menar på att det existerar ett positivt samband mellan handlingsfrihet och motivation, genom att en hög grad av handlingsfrihet genererar i en ökad motivation hos den anställde. Vidare menar forskare att handlingsfrihet har ett nära samband med styrning, då en hög grad av styrning genererar en lägre grad av handlingsfrihet bland anställda och vice versa. Därav kan balansen mellan handlingsfrihet och styrning inte betraktas som en precis punkt på en skala, utan snarare en indikation av anställdas behov av dessa två faktorer. Vi ser ett intresse av att undersöka detta fenomen bland anställda inom hotell- och restaurangbranschen då det återfinns en problematik inom branschen i och med den höga personalomsättningen. Denna problembakgrund leder oss vidare till vår problemformulering som studien avser att undersöka: Skapa förståelse kring vilken inverkan balansen mellan handlingsfrihet och styrning har på anställdas motivation inom hotell- och restaurangbranschen.

     

    Studiens syfte är att skapa en förståelse kring anställdas behov av handlingsfrihet och styrning i sitt arbete och hur det påverkar motivation. Vidare syftar studien till att bidra till ett resultat som kan användas av både ledare och anställda inom hotell- och restaurangbranschen. Denna studie har sin utgångspunkt i en kvalitativ forskningsmetod där vi använder oss av ett deduktivt angreppssätt. Vi har tillämpat semistrukturerade intervjuer vid undersökningen av sex stycken respondenter som är verksamma på olika företag inom den svenska hotell- och restaurangbranschen.

     

    Resultatet av denna studie indikerar att inverkan av balansen mellan handlingsfrihet och styrning på anställdas motivation kan vara av olika karaktär beroende på den enskilda individens behov samt yttre faktorer såsom organisationen och branschens förutsättningar. Då det råder balans för individen upplevs graden av handlingsfrihet respektive styrning som optimal för den anställde vilket i sin tur påverkar motivationen på positivt sätt. Undersökningen visar att anställda efterfrågar handlingsfrihet inom ramar för att gynna en balans och därmed motivationen, där graden av handlingsfrihet är större än graden av styrning. Denna studie indikerar även på att det är viktigt att det finns tillräckligt med stöd, samhörighet och kompetens i samband med anställdas handlingsfrihet, annars tenderar handlingsfriheten att påverka motivationen negativt.

    rättvisande bild av bolaget. För att revisorers arbete ska kunna ses som tillförlitligt krävs

    det att de producerar revision av hög kvalitet, vilket kräver att de är opartiska, har rätt

    kompetens och följer de riktlinjer och standarder som finns. Ett vanligt sätt att mäta

    revisionskvalitet är genom antalet fortsatt drift-kommentarer som utfärdats i

    revisionsberättelsen hos konkursdrabbade bolag.

    Att bristande revisionskvalitet har en negativ inverkan på samhället visades tydligt efter

    de uppmärksammade revisionsskandaler som inträffade under början av 2000-talet. Till

    följd av detta blev revisionskvaliteten starkt ifrågasatt, diskussioner och arbete för att höja

    revisionskvaliteten påbörjades. Forskning fokuserade mycket på att finna vilka faktorer

    som påverkar revisionskvaliteten. Dessa visade varierade resultat och det har även

    efterfrågats forskning med fokus på hur en revisors egenskaper kan påverka

    revisionskvaliteten. Det ger tydliga indikationer till att mer forskning gällande revisorers

    egenskaper behövs.

    Syftet med studien var att genom fortsatt drift-kommentarer uppskatta revisionskvalitet

    för att se om det skett en förbättring mellan åren 2012–2017. Syftet var också att

    undersöka hur en revisors kön, erfarenhet, ålder och storleken på staden revisorn arbetar

    i påverkar revisionskvaliteten. Studien genomfördes med en kvantitativ metod där ett

    urval på 1871 på bolag gjordes. De bolag som inkluderades i urvalet var svenska

    aktiebolag som har inlett en konkurs mellan 2012-01-01 och 2018-03-16. Det krävdes att

    konkursen var inledd inom loppet av tolv månader från det senaste bokslutsåret och att

    bolaget har haft en årsredovisning med en revisionsberättelse tillgänglig.

    Resultatet visar att det skett en procentuell förbättring av revisionskvalitet mellan år 2012

    och 2017. Dock har det endast skett en signifikant förbättring från år 2012 fram till 2014.

    Resultatet visar även att det finns ett negativt samband mellan revisionskvalitet och en

    revisors ålder respektive erfarenhet. Sambandet innebär att yngre och mindre erfarna

    revisorer håller högre revisionskvalitet jämfört med äldre och mer erfarna revisorer.

    Studien visar att det inte förekommer något samband mellan en revisors kön och

    revisionskvalitet. Det identifierades endast ett svagt samband mellan stadsstorleken på

    staden som revisorn arbetar i och revisionskvalitet. Dock finns indikationer att revisorer

    som arbetar i storstäder håller högre revisionskvalitet.

    Analysprogram för grip- och lyftkraft2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    To be able to regulate your grip force and lift an object can be simple for healthy

    people. However, for people with disabilities of neurological diseases such as hydrocephalus

    and Parkinson’s disease it has been found that their diseases can affect

    their grip force. If the grip power is affected, it may be used in healthcare to check

    the course of disease, if it gets better after treatment.

    At the department of Biomedical Engineering - Research and developmet a measurement

    device for analysing grip force and acceleration when lifting an object has been

    developed. In order for this instrument to be more useful in clinical practice, an

    analysis program is required to produce the result after measurements made with

    the equipment. A computerized analysis program has the potential to be significantly

    faster, more efficient and more objective compared to the manual analysis

    used today.

    The purpose of this project was to create an analysis program that can replace the

    work of the manual analysis and which can generate results from measured data.

    The results should not be different between a manual analysis and the automatic

    analysis. The goal was that the analysis should be fast, efficient and objective and

    also provide the same results as a manual analysis would provide.

    The program that was designed became faster and more efficient than the manual

    analysis. Measurements on six healthy volunteers were used to compare the automatic

    and manual analyzes. No significant differences could be detected for any of

    the parameters that were analyzed, and this shows that the results of the automated

    analysis are comparable to the manual analysis and thus can replace these to analyze

    future measurements. However, the automatic analysis has only been tested

    on healthy people, so if the automatic and manual analyzes are comparable even for

    people with a neurological disease should be further investigated before using the

    automatic analysis method on patient data.

    BLOCKET, FACEBOOK ELLER TRADERA?: Påverkande faktorer när unga väljer plattform för digital begagnathandel2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Den digitala strukturomvandling vårt samhälle genomgår har bidragit till att den digitala kompetensen är stor oavsett åldersgrupp. Idag är internet en stor del av vår vardag och används dagligen, både privat, i skolan och i arbete. En konsekvens av digitaliseringen är att stora förändringar har skett i hur handel av varor och tjänster sker och att utbudet av dessa har ökat. Trots att digitaliseringen har stor påverkan på vårt samhälle, är fortfarande forskning inom området till viss del begränsad. Ett exempel på detta är forskningsområdet two-sided markets (TSM). Begreppet TSM har sedan millennieskiftet använts för att beskriva marknader med två kundsidor där handel mellan dessa två sker. I och med digitaliseringen har nya företag och marknader trätt fram där Netflix, Spotify och AirBnb är några exempel på företag som agerar på olika typer av TSM. I denna studie undersöks en typ av TSM, digital begagnathandel, där de två sidorna består av köpare och säljare av begagnade varor.

    Kunders beteende har även det förändrats i och med digitaliseringen och användningen av internet. Hur kunder genomför digitala köp sker nödvändigtvis inte på samma sätt som i traditionella fysiska miljöer. Användandet skiljer sig även åt mellan olika kundgrupper och åldrar. Att företag förstår kunders digitala beteende och hur de väljer plattform är därmed av stor vikt. Nya företag har under de senaste åren trätt in på marknaden för digital begagnathandel och konkurrensen förväntas öka. Vilken affärsmodell och strategi företag använder samt design på plattformar blir därmed avgörande för framgång på marknaden. Den yngre målgruppen, framtidens konsumenter, är mer eller mindre uppväxta med internet och har därför god kunskap om det. De anses ha enorm köpkraft och är därför viktiga kunder för företag som agerar på en TSM. Genom att förstå deras beteende och hur de väljer plattform kan företag vara konkurrenskraftiga. Denna studie har genom kvalitativa intervjuer undersökt hur personer i åldrarna 18–25 år väljer plattform för digital begagnathandel. I denna studie har vi besvarat frågeställningen:

    Vilka faktorer påverkar valet av plattform för digital begagnathandel?

    Resultatet av studien visar att fem faktorer påverkar valet av plattform för digital begagnathandel. Dessa är: användarupplevelse, kundbeteende, social påverkan, prispåverkan och säkerhet. De fem faktorerna har även underliggande attribut som påverkar dessa faktorer. Studien visar även att faktorerna påverkar till olika grad. Social påverkan påverkar till störst grad, därefter kommer prispåverkan, säkerhet och kundbeteende, och den faktor som visat ha minst påverkan är användarupplevelse. Faktorerna påverkar hela beslutsprocessen överlag, dock i varierande grad. Vi kan även konstatera att om köp är återkommande förändras beslutsprocessen och vissa steg kan alterneras eller hoppas över.

    Plastic contacts in particle based simulations2018Independent thesis Advanced level (degree of Master (Two Years)), 300 HE creditsStudent thesis
    Abstract [en]

    Granular materials, large collections of macroscopic particles, are something that is commonly found in both nature and industry. Examples of such can be sand, ore, grains, seeds or snow. Simulations of granular materials are important in many industrial cases. It gives an opportunity to study the behavior of the particles as they interact with machinery and gives an indication of how efficient new designs perform.

    In some areas, such as vehicle-terrain interaction, plastic deformation of the particles can be an important factor. The Ume˚a based company Algoryx Simulation can simulate granular materials in their physics engine AGX Dynamics using a nonsmooth discrete element approach (NDEM), but currently lack support for plastic deformation. The purpose of this thesis is to implement a plastic contact model in the source code of AGX Dynamics, such that plastic deformation can be observed.

    The implementation was first tested for single particle-particle compression where measured contact forces were compared to theoretical models. Uniaxial compression tests were performed for bulk testing, filling a cylinder with particles and compressing them while monitoring the axial stress and strain.

    The results from the single particle compression correspond well to theory, giving the correct plastic deformation for a given contact force and correctly illustrates the effects of changing different model parameters. Plastic deformation could also be observed in the results from bulk testing. Additionally, it was observed that the current version of the implementation is best suited for simulating either very cohesive materials, where particles stick to each other when colliding, or cohesionless materials, where colliding particles are separated after impact. Additional research is needed to study how the separation velocity for colliding particles should be updated in a way that is consistent with the plastic model parameters and experimental results.

    Characterisation of a Gas Modulation Refractometer for Detection of Gases at 1550 nm2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Only very few molar polarizabilities are known with high accuracy; and when so, they are in general only known at a given wavelength. There is therefore a need to assess the molar polarizability with high accuracy of various gases, at different wavelengths.

    The molar polarizability of a gas is a measure of the susceptibility of a molecule to have its charge distribution affected by light. It is also the entity that relates the index of refraction to the (molar) density of a gas in Lorentz-Lorenz equation.

    Hence, for high precision measurements of the density of a gas, it is important to know the molar polarizability of the gas to high accuracy.

    In this work a GAMOR system has been used to determine the wavelength-dependent molar polarizability of Ar at 1550 nm.  However, a high accuracy assessment of the molar polarizability of a gas requires that the gas density is known with high accuracy. Since this is not trivial to assess, the molar polarizability of argon has been assessed in terms of that of nitrogen, which is assumed to be known with high accuracy. Hence, to minimise measurement errors, the measurement cavity was alternately filled with nitrogen and argon and the ratio between the signals provided by the GAMOR system represents the ratio of the molar polarizabilities of the two gases. It was found that the molar polarizability of argon was  0.94393(5) times that of nitrogen. Since the latter one has been assessed to 4.34828(3) x 10^-6  m^/mol, the molar polarizability of argon could be assessed to 4.10446(5) x 10^-6 m^3/mol.

    Field-Aligned Currents and Flow Bursts in the Earth’s Magnetotail2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    We use electric and magnetic field data from MMS spacecraft between 2016 and 2017 tostatistically investigate earthward propagating plasma flow bursts and field-aligned currents(FACs) inside the plasma sheet of the geomagnetic tail. We observe that the occurrence rateof flow burst peaks around the midnight region with decreasing trend towards Earth and theplasma sheet flanks. Further, we distinguish between long and short FACs. Long FACs laston average 6 sec and have a magnitude of 5-20 nA/m 2 . Short FACs last on average 10 timesshorter and have an magnitude of 10-50 nA/m 2 . Both, long and short FACs occur on averageone time per flow burst, on minimum 0 times and on maximum 4 times per flow burst. Intotal, 43 % of the observed FACs are located in a flow burst, 40 % before and 17 % right after aflow burst.

    Wave study Seaflex mooring system: Wave study to illuminate how first and second order wave force transfer to and affects the loading of flexible Seaflex mooring system2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    When constructing a marina, one must consider many factors for calculating the mooring forces transferred to the mooring system of the docks. The forces transferred from waves is of course one of the most important. The wave induced forces may be described in different orders, the first-order wave forces from the frequency domain and the second-order wave forces determined from a wave field of different standing waves acting together. All floating objects are subjected to these wave forces, but for different mooring systems the transferred mooring force may vary. To describe the need for different calculations depending on the mooring system, a comparison to a spring system is made for both a Seaflex hawser and a guided pile system, which illustrates a significant difference in transferred mooring load. This is due to the hysteresis giving a low spring constant to the Seaflex hawser, which in turn transfers very little of the frequency induced first-order forces to the mooring system. This gives the conclusion that different methods for scaling the Seaflex mooring system is needed, since the first-order wave forces are not as significant than for a semi-rigid mooring system.

    Integration of hydrothermal processes on a forest-based biorefinery site2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The pulp and paper industry (PPI) is a business that produce large amounts of residues annually. Besides bark, large quantities of sludge are produced from the various parts of the industrial process. The sludge that comes from the biological wastewater purification process is denoted biosludge and is known as a particularly problematic waste product. It is of interest to reduce the amount of sludge from the PPI or to find new ways of handling the produced sludge. The common way to treat the PPI sludge is by incineration in the site’s bark boiler. The material is however difficult to dewater and often does more harm than good in the boilers. Different technologies to try and dewater the sludge further have been investigated previously, one that has recently been noted is hydrothermal treatment. The technology described in this thesis work is called hydrothermal carbonization (HTC) which uses water as a reaction media to turn the sludge into a coal-like material called hydrochar. The hydrochar has a higher heating value than the initial sludge and is more hydrophobic which makes it easier to dewater.

    This Master’s thesis describes the process technologies of the HTC process and presents some of the recent work done within the area. The properties of different residues from the PPI are presented before the integration of an HTC process on the biorefinery site in Domsjö, Sweden is discussed using previously published articles. A survey concerning sludge from industries within a 500 km range of the Domsjö biorefinery site is made to investigate whether residual streams similar to the ones at the Domsjö site are available in the vicinity.

    The results show that an HTC process demands energy in the form of steam and/or electricity. A previously made pinch and total site analysis show that the most accessible steam at the Domsjö biorefinery site, that most appliances and process steps uses, is at 7 bars. There are also steam levels of 20 and 32 bar in the area, which is within the range an HTC plant requires. The HTC process water demands further treatment which puts an extra stress on the already existing water purification process. The Domsjö biorefinery site produces 6000 tonnes of biosludge per year. Several HTC companies produce units that normally treat 20000-50000 tonnes of sludge per year, which indicates that additional sludge could be added to reach full capacity. The survey shows that there are similar materials available in the surroundings. It is concluded that further investigations concerning the sludge materials must be made before real implementation consequences can be calculated.

    Can hidden Markov models be used for inference about operational risk?2018Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to investigate the possibility if hidden Markov models (HMM) can be used for inference about operational risk given financial time series data of Auditchanges and Audit prices. The models tested vary in the number of possible states each underlying latent process can take. All models have been implemented usingR-statisticalsoftware along with the depmixS4 package. From the evaluation of the work, it was shown that there was a clear difference between the states, according to the the types of observation they emitted, for the final model. The thesis shows that the biggest factors affecting operational risk were the number of changes of the trades and the time between those changes. It also showed that it was, in large part, the same trader who carried out all the trades as well as changes and only within the internal department. The final conclusion is therefore that HMMs are possible and appropriate to use for inference about operational risk, but that more labeled data are required to express the models predictive performance.

    Cash Flow Simulation in Private Equity: An evaluation and comparison of two models2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The uncertain pattern of cash flows poses a liquidity and risk management challenge for investors of private equity funds. The structure of a private equity investment, where the total committed capital will be paid out in portions at an undetermined schedule, makes it vital for the investor to have sufficient levels of cash in order to meet the called capital from the fund manager. As an investor can hold several investments, it is important to predict future cash flows in order to have effective cash management.

     

    The purpose of this thesis is to increase the supporting institution’s knowledge in cash flow predictions of investments in private equity. To do this, an analysis and evaluation of two models have been executed for cash flow predictions from the view of a limited partner, i.e. the investor. The comparison is done between a deterministic model, the Yale model, that is currently used by the supporting institution to this thesis and a new stochastic model, the Stochastic model, that has been implemented during the work of this thesis.

     

    The evaluation of the models has been done by backtests and with a coefficient of determination test, R2 test, of the Institution’s portfolio. It is hard to make an absolute conclusion on the performance of the two models as they outperform each other on different periods. Overall, the Yale model was better than the Stochastic model on the conducted tests, but the Stochastic model offers desirable attributes from a risk management perspective that the deterministic model lacks. This gives the Stochastic model potential to outperform the Yale model as a better option for cash flow simulation in private equity, provided a better parameter estimation.

    Installation av frikyla och vilka kostnader det innebär: Projektering och kostnadsberäkning för användning av frikyla i kylsystem2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this work, a refrigeration centre with the use of free-cooling has been projected, drawn and then cost-calculated. The work began drawing a flowchart for the cooling system in the cooling centre, this flowchart were drawn in a program called Autodesk Autocad. After that, the work continued by drawing and projecting the cooling centre with the reality of a threedimensional modeling. This projection was done in Autodesk Autocad´s MagiCAD plug-in. Meanwhile when these flowcharts and model drawings were constructed, communication with manufacturers and suppliers of the major machines in the system was done parallel with the modeling. This was made to get the correct values, measurements and budget sacrifices. Once both the flowchart and the three-dimensional, realistic looking model were completed, a product calculation was initiated in Wikells Sektionsdata. The calculation includes all products in the entire refrigeration centre, as well as things that were previously unpublished. Examples of items that were not in the flowchart nor the three-dimensional model, but included in the product calculation are welding work, bolt joints, primary and secondary works. A product calculation was made for the system both with and without free-cooling, just to see how much the free-cooling installation will cost. The result was that the freecooling installation will cost 1 225 725 SEK. Subsequently, calculations were made to see how profitable it is for the company to invest in free-cooling. These calculations were made largely from an energy calculation from Ramböll. With those calculations, there was a result in the form of payback time. The payback time for free-cooling was calculated to just under 8,3 years.

    Energiuppföljning på två flerbostadshus i centrala Skellefteå.2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    One third of Sweden's energy use is used by residential and commercial buildings, of which nearly 60 % go to heating. Opportunities are great for using energy more efficiently and there is a great potential to save energy by improving the construction of the building. The EU places higher demands on energy use and means that monitoring of energy use is becoming increasingly important. From 2021, all new production of buildings in EU Member States will be "close to zero energy houses". The definition of "near zero energy house" has not yet been established in Sweden, but in a throw-out of BBR is the requirement to tighten by 40 % discussed. Efforts to get more energy-efficient buildings are under way and are being carried out in close collaboration with BBR.

     

    This degree project has been carried out on behalf of Skebo, where the goal is to establish the real specific energy use in operation for two properties in Skellefteå, Ringduvan and Odenskrapan. Compare and analyze deviations from projected specific energy use. Ringduvan was ready for occupation in spring 2014 and Odenskrapan in early 2016.Both buildings have electricity and district heating from Skellefteå Kraft. Ringduvan is projected by NCC and Oden of Lindbergs Energi & VVS AB.

     

    Sveby ("Standardize and Verify Energy Performance in Buildings") is a development program run by actors in the construction and real estate industry. Svebys aim is to develop an industry standard that increases the accuracy of the project between projected and real energy use. With increased knowledge of user-related use, a standardized approach, energy monitoring and enhanced cooperation between actors, the goal is to reduce the deviations. Operators in the industry may choose to enter into a Sveby agreement, which includes a common method of procurement, design and verification.

     

    The projected specific energy use for Ringduvan is 76 kWh/m2,year and the real is 101 kWh/m2,year. Odenskrapan projected is 53 kWh/m2,year and the real is 93 kWh/ m2,year. That is, the specific energy use exceeds the estimated energy consumption by 33 % for Ringduvan and 75 % for Odenskrapan. This means that much more district heating and real estate is needed than expected.

     

    In general, potential causes of higher energy use have been identified. But nothing has been confirmed and more work is required against the buildings in order to compare and identify the exact reasons.

    Abstract [en]

    Background Adolescents aiming to become elite floorball players need to eat optimally to perform during practice, games and in school. The diet is an important factor to the

    adolescents who are still in a growth and development phase and an improper diet can lead to injuries, sleep disorders and eating disorders.

    Objective The purpose of the study is to evaluate the food and meal situation for pupils who are studying at the nationwide sports gymnasium with floorball alignment.

    Method A quantitative method was used and a web survey was distributed to the 46 pupils at the nationwide sports gymnasium, all the pupils responded. The questionnaire concerned their food and meal situation. The level of significance was set to p<0,05 and differences between groups were tested with Chi-square or Fishers exact test.

    Results The majority of the pupils cooked dinner daily and rarely ate ready-made meals. A significant difference was seen depending on what grade the pupils went in and how often they cooked with friends (p = 0.046). More than half of the students in grades one and two cooked food together with friends at least once a week compared to one third from in grade three. One other difference between the grades could be seen how often they cooked so they could get food boxes for days to come. The majority sometimes cooked food boxes while some pupils in grade one and two never did it (p = 0.049). Pupils had a perceived good knowledge of both the practical to cook a meal and the theoretical planning a meal.

    Conclusion Overall, the pupils experienced that they had good practical and theoretical knowledge about cooking and the majority cooked dinner daily. Basic dietary knowledge in the curriculum and posts concerning food and diets on social media can be contributing factors.

    Abstract [en]

    Abstract

    Background Households produce the biggest amount of food waste and the amount of groceries being bought online increases by every year. A big part of these purchases are pre-planned grocery bags with recipes and associated ingredients, which is an effective concept based on a time-saving perspective. This area was largely unexplored and it is not known how effective it is through a food waste-perspective. 

    Objective The aim with this study was to examine food waste among consumers who bought pre-planned grocery bags online. If there was any food waste, which groceries were thrown and by what reasons?

    Method A quantitative method has been used where data was collected through an online survey. It was distributed by an ICA-store in Umeå to their customers who bought pre-planned grocery bags, but also on Facebook and different forums on the internet.

    ResultsA total of 126 respondents participated in the survey and the majority discarded food by every fifth or fewer times and vegetables was discarded the most. Those who bought Family bag were shown to cause food waste more frequently (p=0,025), more fish/meat (p=0,032) and vegetarian products (p=0,032) than those who bought other grocery bags. The results showed large variation regarding the question if the respondents perceived wasting more food when purchasing pre-planned grocery bags online, compared to when they bought groceries in a physical store.

    Conclusion The majority of the respondents in this study caused a small amount of food waste when purchasing pre-planned grocery bags and the reasons to food waste were shown to be many with great variation. Two common reasons to food waste were that the recipes weren’t appealing and food didn’t taste good enough. This can be interpreted that the grocery bags weren’t optimized in a food waste perspective. To purchase Family bag were shown to be significative with increased food waste.

    Näringslära: I hem- och konsumentkunskapsundervisningen2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund Folkhälsoproblematiken ökar allt mer i Sverige. Elever behöver därför få kunskap om hur måltider sätts samman efter individuella behov, vilket också är ett kunskapskrav i läroplanen för hem- och konsumentkunskap (HKK) i grundskolan.

    Syfte Studiens syfte var att studera vad HKK-lärare anser om elevers kunskaper i näringslära, samt hur det påverkar deras möjligheter att undervisa mot kunskapskraven i HKK.

    Metod En webbaserad enkätstudie, skickades ut till HKK-lärare i Sverige, vårterminen 2018. Rekrytering skedde i två Facebook-grupper för HKK-lärare.

    Resultat Totalt deltog 86 HKK-lärare. Alla utom fyra ansåg att eleverna hade otillräckliga kunskaper inom näringslära när de kom till HKK-undervisningen. Av dessa ansåg 73 lärare att kunskaperna var så låga att det påverkade deras undervisning. Strax under hälften av alla ansåg att eleverna behöver näringsläran för att kunna tillgodogöra sig undervisningen. Alla utom fem uppgav att de undervisar i både tallriksmodellen och näringsämnena inom området ”individuella behov”. De som arbetar ämnesövergripande med andra ämnen inom kost och hälsa såg framgång hos eleverna, de uppgav dock att det var svårt att få till samplanering. Det fanns ingen skillnad mellan grupperna, yngre och äldre lärare, vad gäller ämnesövergripande arbete (p = 0,80). 

    Slutsats Resultaten tyder på att HKK-lärare anser att elevers kunskaper i näringslära är otillräckliga. Så pass att flera anser att deras undervisning påverkas. För att öka elevernas kunskaper bör ämnena i skolan arbeta ämnesövergripande. För att lyckas krävs det att skolledningen möjliggör det genom att skapa rutiner för lärarna att följa kring samplanering.

    Optisk mätning av koncentrerade paraboliska solfångare: Kvalitetssäkring av den geometriska formen på tråget2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Absolicon Solar Collector AB has started to investigate the possibility to implement a quickquality insurance for concentrating parabolic solar collectors to their new power train. This will be done by calculating the geometrical shape on the trough by letting cameras move over the through and detect the edges on the reflected receiver pipe. Measure data will be sent to a central computer through Message Queuing Telemetry Transport(MQTT) that handles the calculation of the troughs geometrical shape. The project has been named ARGQOS and is an acronym for Absolicon Robotized GeometricalQuantification Ocular System. In the project eight identical camera houses should be designed, constructed and tested where the camera and the computer would be mounted. LED-lights should also be located on top of the camera house to communicate the operational status of the unit to the operator. The software also had to be developed for edge recognition algorithms, communication to the system central computer over MQTT, where measure data and other important information will be send. Tests has been made to determine the function of the camera house where the first test consisted of the evaluation of the hardware of the camera house for industrial usage. The second test that was made was the evaluation of the software and a test scheme was established to mimic a real measurement on a concentrated parabolic solar collector. Even the communication with the central computer trough MQTT was tested. In the third test a measurement was done to a real concentrating parabolic solar collector to see how well the reflected edges could be detected. Also the status of the solar collector by calculating if the detected points hit the receiver pipe or not. The fourth and final test that was made was to validate the method by first measure a defect parabolic solar collector with a laser to where the laser hit and missed the receiver pipe and then measure the same solar collector with the system ARGQOS and compare the results. The tests show that the camera houses have the intended function for industrial usage and that the program is working well and is stable with only a few minor bugs. Measurements on parabolic solar collectors can be done repeatedly without any problems. The cameras could detect the reflected edges on almost the whole trough with only a few problem areas. It also displayed that the measurement was sensitive to outer disturbances that was reflected in the trough and the system was sensitive to the ambient light. In the validation test the comparison between the measurement between the system and the laser displayed the same result. More tests need to be performed to be sure that the validation holds.

    Från tweet till revolution: En jämförande studie av mediefenomenet #metoo2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    On October 15th, 2017, the American actress Alyssa Milan posted a tweet on the Social Media Platform Twitter which soon would have led to major consequences for people across the globe. Milano urged her followers to comment “#metoo” on the post if they had ever been subjected to sexual harassment or abuse – an action of hers which quickly evolved into a widespread campaign in USA as well as in other countries, there among Sweden. With #metoo's great impact, we now have a unique opportunity to explore today's gender equality debate and feminist discourse based on the new type of networking community. Thus, this study aims – with a comparative as well as a charting intention – to further explore the #metoo phenomenon based on media reporting from the largest daily newspaper in Sweden (Dagens Nyheter) and in the USA (USA Today). The main purpose is to investigate how the journalism takes place in relation to contemporary gender discourse and how it differs between these two countries; which in the long run aims to contribute to increased knowledge about the inherent gender equality issues of #metoo and the discursive image of these problems each media has chosen to reproduce to their fellow residents. The method used in the study is sorted under a qualitative content analysis focusing on the interpretation and understanding of contentive meaningful aspects. Results show that articles from USA Today and Dagens Nyheter differ a lot in how they relate to theoretical concepts of performativity, normalization, power, and a broader understanding of gender structures. Correspondingly, large differences can be identified in how the articles relate – or lack to relate – to a further perception of "a male perpetrator" and "a female victim”. This variation is primarily derived from a lack of structural thinking in relation to perceptions about gender at the expense of a more individual- and celebrity- focused journalistic view but could also be partly correlated to an absent lingua franca within the gender discourse of these two countries.

    "Vi är överallt": En diskursanalys av relationen mellan AIK och dess supportrar på sociala medier2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Title: “We are everywhere” – an analysis of the discourse surrounding AIK football club on social media

     

    The purpose of this study is to discern what the discourse surrounding Swedish football club Allmänna Idrottsklubben (AIK) and its fans look like on the social media platforms Facebook, Twitter, and Instagram. This is done by examining every post by AIK on these platforms and the fan response to each post. The opportunities for clubs such as AIK to communicate directly with its fans has increased greatly with the invention of social media, and this breakthrough in communication has also had the added effect of allowing fans to much easier voice their own opinions. Thus, we are presented with an area of communication that represents an interesting object of study.

     

    The method used is based partly on Ernesto Laclau and Chantal Mouffes theory on discourse analysis and partly on Roland Barthes theory on myths. Both theories offers some tools for analysis and when combined provides the opportunity for in-depth study. The results show that the discourse is largely centred around nodal points such as “Love”, and “the Club Emblem”. Through these AIK communicate the importance of itself to its fans and gives them a reason to “be a part of something greater”. Some of the myths found such as the “Family myth” or the “Hero myth” adds to this notion. However, the supporters don’t always agree with AIK which is why another major theme in the discourse was their “Criticism”. The supporters could also be found arguing among themselves about what being an AIK-fan meant which exposed the “True-fan myth”. Through all of this the study found sign of an underlying importance of active participation within the fandom, which enhanced the experience of being a supporter.

     

    Key words: AIK, discourse analysis, fandom, supporter, myth, nodal point, communication, football

    "Vad innehåller lokaljournalistiken?": En veckas lokaljournalistik på webben i Västerbotten2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study ”What’s does the local news contain? - an analysis of a week’s local journalism on the web in Västerbotten, Sweden” examines the different discourses in the local journalism of newspapers and public service media. The aim is to find what makes the local news with the use of a quantitative content analysis combined with a Critical Discourse Analysis (CDA).The study uses a theoretical framework that includes theories surrounding agenda setting, the power of the media, local journalism, news values and web based journalism. For the quantitative content analysis the online text tool Textometrica was used.The analysis found that the local news mainly consisted of news regarding sports and negative news such as crime, accidents and court cases. It also found that the local news mainly focused on a small part of the municipality of Västerbotten in its news coverage, where the biggest city in the region was of the most interest. When other parts were covered it was mostly for sport events or negative news. The qualitative analysis also found that there was a high frequency of updates on the websites and non-local news that made it into the local news due to being sensational. A difference between the newspapers and the public service media was also found where the papers focused more on local debates and public service media wasn’t as tied to earlier theories regarding news values.The study could also state that the content of the local media during the week differed from what is said to be good journalism and also what is said to be the journalistic responsibility that citizens rely on to make democratic decisions.

    MAKING HERSTORY: En kritisk analys av dramatiserad kvinnohistoria i visuell media2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The media is not only a source of entertainment, it is also a way to better understand ourselves and a means to shape our identities. The purpose of different types of communication are never neutral, there is always a discourse and an underlying meaning at work. By continually portraying women as stereotypical characters, the patriarchal discourse is reproduced and perpetuates an unequal view of women in society. It is possible to reconstruct the hegemonic male domination and representation is key if there is a change to be had in this area. Thus, it is of utter importance to create productions that showcase a vast variety of social and gender roles.

    The purpose of this essay is to analyse female representation in visual media with a primary focus on women’s history, exemplified by how gender is created by female characters in the miniseries Fröken Frimans krig. The analysis has a basis in multimodal critical discourse analysis as well as critical narrative analysis, and also takes into consideration Mulvey’s theories on the male gaze. The theoretical framework is based on poststructural feminist theory with an aim to deconstruct notions of what constitutes a woman and a man.

    ”I look flawless all day long”: En studie av diskurser om skönhet i material producerat av influencers2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The internet and social media networks have created a changed world of media. Influencers work with creating content on these platforms. This study is focused on five female influencers which each has a large audience of viewers and that work within the category of beauty. They make content that mainly focuses on makeup and fashion. The study's aim is to examine discourses about beauty, identity and emotions in content created by these influencers, and to examine if norms and ideals about beauty is reproduced or challenged. The study relies on a theoretical framework with theories about influence marketing, identity and self-presentation online, the consumer society and how it relates to beauty, gender analysis, and also the role of emotion in cultural politics. The study uses two methods, the first being an analysis of content posted on Twitter using the tool Textometrica and the second being a multimodal discourse analysis of ten videos posted on YouTube. The results show that western ideals of beauty often are reproduced in this material, and that they are reproduced in different ways and forms. Multiple themes and topics within the discourse is discussed. These for example involving who the influencers are and what it takes to become a popular influencer, the identities these influencers build online and aspects of how they create their content, the myth that anyone can become as beautiful and sellable as the influencers if only they use the right products in the right ways, how the body and someone's appearance is seen as a never-ending project that can always be improved and also at theme about an internalised judging gaze. Beauty in this discourse is a word that metonymically becomes sticky with positive values and emotions and almost becomes a synonym for concepts of happiness and health. To be ideally beautiful becomes equivalent to be happy and confident.  To be ideally beautiful becomes equivalent to be healthy. The reproduction of these norms is problematic in many ways, where one of the most important is that it excludes people that does not live up to the norms. It can also be harmful in a way of effecting mental health and wellbeing of the people trying to live up to these norms.

    Visuell programmering av parametriskt modifierbart markobjekt vid broprojektering2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this report is to investigate whether, by means of visual programming, you can create parametrically-modifiable terrain objects to the Tekla Structures BIM program. The pros and cons of such an approach will then be analyzed and discussed, and the conclusions that can be drawn are presented. The report will begin by presenting some theory about the type of bridge construction used in the project and the different software used. After that, a review of the project will come and finally, the completed terrain object will be reviewed, and its different parts from the visual programming will be displayed and explained.

    The result of the work is that terrain objects can be projected in this way, but some problems exist with the ability to easily use the same model for different projects, as most project are different and unique

    Abstract [en]

    This studies purpose is to analyse the representation of media in the television series Mr. Robot as well as to analyse the representation of the prominent conglomerate called E-Corp that is central to the narrative of the series.  Theories used in the study is mainly concerned with mapping out the semiotic signs as well as using theories of representation by Stuart Hall to further understand the meanings behind the signs that are distinguished in the analysis. Foucault theory about panopticons is implemented when looking at surveillance from E-Corp as well as Jones theory about techno- and grunge-economies.  The results of the study show that media is often represented as lying or being shallow. According to the series it’s easy to get stuck in a simulation of reality where you can’t tell the difference between what’s real and what’s hyperreal. The representation of the corporation shows little about the regular employee but emphasizes that those in charge often are bad or simply manipulative people.

    Centralised Distribution Grid Energy Storage Systems: Placement and Utilisation for Grid Expansion Deferment2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Following an ongoing change towards an increasingly renewable power generation system Swedish grid operators are facing several challenges in coming years. As authorities plan for the decommissioning of nuclear power an increased reliance on de-centralised energy sources such as photo-voltaic distributed generation (PVDG) is expected. A technology observed in some cases to accompany local power quality issues severe enough to impose grid expansion measures from distribution system operators (DSOs). Considering a combination of an indicative utilisation inefficiency of classical grid expansion measures and a recent year maturing of various energy storage technologies, this report sets out to evaluate the possibility of utilising centralised energy storage systems (ESSs) for deferment of classical grid expansion measures.

    For the purpose of identifying the most prominent problem scenarios of modern production- and consumption behaviours as well as the possible solutions offered by centralised ESSs, a literature review of journal articles and technical reports was conducted in combination with a case-study of an existing urban grid operated by Umeå Energi Elnät AB (UEEN). The work regarding ESSs is directed with specific focus towards evaluating which ESS services can potentially facilitate grid expansion deferment and what ESS placement is advisable for efficient utilisation. Assessing possible grid safety implications, potential for peak load shaving and the presently most suitable energy storage technology was also within the scope of the study.

    The literature review reveals PVDG induced feeder line over-voltage and transformer overload the most likely and previously observed implications imposing grid expansion measures. The former more prominent in elongated, typically rural, grids and the latter in more densely populated urban grids. For deferment of over-voltage related grid expansion measures a centralised ESS can be utilised for voltage support provided placement is made close to the affected grid section, presumably far out the affected feeder line. This result is coherent throughout the reviewed literature and is supported by the results of the case-study. Distribution transformer overload and its imposed grid expansion measures can be deferred through load re-allocation and peak load shaving, two services proven achievable by centralised ESSs and the capacity for which increases if ESS placement is made closer the distribution transformer.

    Provided present regulatory and standards are adhered to upon installation, significant negative impact of centralised ESSs on distribution grid safety can be avoided. Most energy storage technologies, including battery based energy storage technologies indicated from the literature review providing the most suitable characteristics for use in centralised distribution grid ESSs, utilise well established systems for grid connection hence no presently unsolvable grid safety implications are identified. Technical reports of real applications of centralised ESSs reinforce this argument as successful implementation without ESS caused grid safety implications have been achieved in the Swedish distribution grid in the past.

    Ancient DNA in paleosols, SW Greenland: A tool for retrospective paleoenvironmental studies?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Ancient DNA (aDNA) is a useful tool for retrospective paleoenvironmental studies. Paleosols formed in Arctic environments constitute a potential archive of aDNA from terrestrial organisms living in past environments, given that the cold and dry climate prevailing at high latitudes favors DNA preservation and hamper post-depositional mobility of deposited fragments. However, to what extent aDNA is preserved in old buried soil layers (paleosol layers) are not well known. This study asses to what extent DNA older than 100 years is present in a paleosol profile from southwest Greenland. My main hypothesis was that aDNA from both plants and animals could be extracted from old buried soil layers. I found that oldest studied soil layers were more than 800 B.P. yr old. These old layers contained DNA from both plants and animals. The clean sampling protocol used showed no signs of contamination, suggesting that the DNA was from soil layers and not from modern contaminants. I conclude that my hypothesis seems valid and that a majority of the analyzed plant and animal DNA is ancient. Indeed, aDNA could be used to infer species presence in past paleoenvironments and widen our knowledge regarding how Arctic organism coped with climatic perturbations and thus, improve our understanding how they will respond to future climatic change.

    Supervision in the contact zone revisited: Critical reflections on supervisory practices through the lenses of time, place and knowledge2018In: Postcolonial Directions in Education, E-ISSN 2304-5388, Vol. 7, no 1, p. 37-61Article in journal (Refereed)
    Abstract [en]

    This article contributes to the discussion on intercultural doctoral supervision through a reflexive analysis of one supervisor’s practices during a joint Laotian/Swedish capacity-building project in 2005–2011. My practices were guided by postcolonial/feminist aspirations to shift power relations and to disrupt knowledge-production practices to allow what Singh (2011, p. 358) calls “pedagogies of intellectual equality”. These ideals, however, were challenged by the formal structure of the PhD programme and my socialisation into a Swedish/Western rationality about what a ‘good’ doctorate is. Using the conceptsof time, place, and knowledge (Manathunga, 2014), I reflect here upon my own practices and actions during supervision of four doctoral students from Lao People’s Democratic Republic. This supervision took place in what Pratt (2017/1990) calls the ‘contact zone’, the space where intercultural meetings take place. Manathunga (2014) argues that time, place, and knowledge are crucial to understanding intercultural supervision. I analyse the opportunities and challenges I met as a supervisor, and critically reflect upon how postcolonial theory and concepts of time, place,and knowledge can contribute to discussion on disrupting hegemonic patterns of knowledge production in doctoral training. The analysis shows how supervision in the contact zone may support assimilation at the expense of transculturation, the blending of knowledge from different contexts to create new knowledge (Manathunga, 2014, p. 4). The analysis also points to a third path, accommodation, towards the needs and strategies of doctoral students and supervisors affecting and changing training in unexpected ways.

    Abstract [en]

    This study aims to examine what happens when the Japanese food culture meets the Swedish. The purpose is to examine the cultural tension on an individual level when a person integrates into another food culture, with a focus on Japanese people. This study is based on semi-structured interviews. Background information was gathered through a systematic database search followed by a thematic analysis. The thematic analysis gave four themes: eating at restaurant, differences between restaurants in Japan and Sweden, differences in social behavior and Japanese adaptation to new food culture. After the informants came to Sweden their dining at restaurants has become less frequent which is caused by an inferior range of restaurants. The informants thought the service at restaurants were bad in Sweden compared to Japan because they might be used to the systematic service in Japan. The purpose of eating out at restaurants has changed from a social to a nostalgic purpose. There are further differences in behavior when eating, for example lifting your plate when eating in Japan. After moving to Sweden, the informants were forced to change their diet because some japanese ingredients may not be available. They either swap Japanese ingredients to Swedish or use the ingredients that exist.

    Abstract [en]

    The purpose of this study is to clarify and explain the term terroir from an interdisciplinary point of view. A field study was conducted in Burgundy where observations took place as well as qualitative interviews with winemakers about their relation to terroir. The study includes a scientific background that illustrates several different viewpoints on terroir as well as economic, psychological, relational and sensory aspects which are all connected to illuminate the complexity of terroir. The acquired data was analysed through a qualitative data analysis and the results show that terroir is a complex, relativistic term that influences many aspects of life in the region including viticulture, vinification, economics and social relations.

    Abstract [en]

    How cookbooks' design and content have changed is an area that has not been investigated to a greater extent. Cookbooks are part of cultures culinary history, which allows you to understand who the food was cooked for and which food was cooked. The essay is about how cookbooks changed from 1755-1951 in terms of design, structure and content. Five cookbooks with about 50 years intervals have been studied to see similarities and differences. The method is based on a content analysis of five books where the foreword and recipes have been compiled, analyzed and compared to each other to see how they have changed during this time period. The result shows that there are differences in the books but also some similarities. In particular, we can see that technical developments have influenced the contents of the books due to the raw materials and cooking methods that were used. By contrast, the target group has not changed during this period.

    Ourclimate is changing ata rapid speed whichleads to older constructions with less thermal insulationhaving a higher chance of experiencingproblems with ice on roofs. This could also become a problem for future construction if not the right amount of insulationis chosen.The intention of this thesis is to investigateif it’s possible for ice formations on roofs with low slopewhen theinside temperature is20°C.The goal is to prove with calculations and simulations if there is any chance of ice toform on the roof constructions.The thesis will be carried out with calculations for a stationary one-dimensional heat transport together with the simulation program WUFI Pro to be able to make comparisons in the results.The results display that the choice of insulationinfluences the condition of snow melting on the roofs. However, the snow depths havea greater influence on the hours of snow melting.In conclusion, the thickness of the insulationcan make a difference for ice formation even though the snow itself has a higherimpact.

    Energieffektivisering vid platta på mark för lättare byggnader vid ändring av grundläggningsmaterialet2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Energy efficiency of buildings is becoming increasingly more relevant in an industry where energy requirements are getting higher and higher. The different options for achieving a more energy-efficient building are few and generally aimed at increasing the insulation thickness ofa specific building component. This may prove to be a challenge in urbancities where plot areas are limited, and the possibility of increasing wall and roof thickness’s is not a viable option.This report examines the possibility of replacing the architectural concrete in the foundation to a lighter, more insulation concrete called LWAC, or lightweight aggregate concrete. This would in turn reduce the building’s heating demand by increasing the foundations insulation capacity and reduce the buildings overall heat loss. This replacement takes place in the energy simulation program IDA-ICE. In IDA-ICEsix simulations are performed in six different cities around the world. Allthe simulations are performed for a building model that has the same structure, material layers, installations and characteristic material values as an existing building, Backen 6:1, located in Umeå, Sweden. In the simulations, the heat demand for the model are compared while using architectural concrete in the foundation vs using lightweight aggregate concrete. The results from these six simulations showsan overall decrease forthe buildings U-valuebut an increase in the building’soverallheat demand. This result is later linked to the lightweight aggregate concretes lower density and inferior heat storage capacity compared to the architectural concretes higher density and superior heat storage capacity.

    Perfusion magnetic resonance imaging changes in normal appearing brain tissue after radiotherapy in glioblastoma patients may confound longitudinal evaluation of treatment response2018In: Radiology and Oncology, ISSN 1318-2099, E-ISSN 1581-3207, Vol. 52, no 2, p. 143-151Article in journal (Refereed)
    Abstract [en]

    Background: The aim of this study was assess acute and early delayed radiation-induced changes in normal-appearing brain tissue perfusion as measured with perfusion magnetic resonance imaging (MRI) and the dependence of these changes on the fractionated radiotherapy (FRT) dose level.

    Patients and methods: Seventeen patients with glioma WHO grade III-IV treated with FRT were included in this prospective study, seven were excluded because of inconsistent FRT protocol or missing examinations. Dynamic susceptibility contrast MRI and contrast-enhanced 3D-T1-weighted (3D-T1w) images were acquired prior to and in average (standard deviation): 3.1 (3.3), 34.4 (9.5) and 103.3 (12.9) days after FRT. Pre-FRT 3D-T1w images were segmented into white-and grey matter. Cerebral blood volume (CBV) and cerebral blood flow (CBF) maps were calculated and co-registered patient-wise to pre-FRT 3D-T1w images. Seven radiation dose regions were created for each tissue type: 0-5 Gy, 5-10 Gy, 10-20 Gy, 20-30 Gy, 30-40 Gy, 40-50 Gy and 50-60 Gy. Mean CBV and CBF were calculated in each dose region and normalised (nCBV and nCBF) to the mean CBV and CBF in 0-5 Gy white-and grey matter reference regions, respectively.

    Results: Regional and global nCBV and nCBF in white-and grey matter decreased after FRT, followed by a tendency to recover. The response of nCBV and nCBF was dose-dependent in white matter but not in grey matter.

    Conclusions: Our data suggest that radiation-induced perfusion changes occur in normal-appearing brain tissue after FRT. This can cause an overestimation of relative tumour perfusion using dynamic susceptibility contrast MRI, and can thus confound tumour treatment evaluation.

    Abstract [en]

    The introductory chapter in this study introduces the reader to the overall problem that concernsLawrence Kohlberg and Sven G. Hartman's moral education models. The purpose and questions ofthis studie specifies the overall problem in order to facilitate the process of answer the researchquestions, which is largely about which of Kohlberg's and Hartman's theory one can reasonablyadvocate in the context of, when teachers plan their lessons. Also how do the theories relate to eachother based on the source material. This chapter also describes the hermeneutical method anddocument analysis used to answer the questions. Both Kohlberg's and Hartman's theories aredescribed in this chapter, as well as a problematisation of them. Since the source material consistsof freely written texts of young people, this chapter also discuss ethical considerations. Chapter Twopresents the result, consisting of quoted texts written by the youngsters. The texts presents theirthoughts and arguments about different moral or ethical problems. These problems are divided intothree categories, material and resource distribution, power distribution (political) and solutions toinequality. This chapter also includes the analyses of the result by Kohlberg's and Hartman'stheories. Chapter three, analysis and discussion, answers the questions as to whether teachers haveany benefit from these theories, as well as what one can derive from comparing these theories witheach other. In conclusion, this chapter presents a discussion about which theory is most suitable touse by teachers in the schools, based on the source material. Although the chapter, analysis anddiscussion, mentioning advantages of both theories, the analysis suggests that Kohlberg's theoryweighs a little heavier in a school kontext than Hartman's theory.

    Seed rain and dispersal possibilities between process domains: Comparing seed dispersal abundance between lakes, rapids and slow-flowing reaches2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Process domains are formed by geomorphological process, these geological formation act as water pathways for river systems and affects hydrochory potential for seeds. Hydrochory acts differently depending on fluvial settings and is an important factor for diversity in the riparian zone along streams and lakes. The aim of this study was to (1) determine if process domains influence plant species abundance and diversity, and (2) if certain environmental factors associated with different process domains affects species abundance and diversity. The sample sites are parts of a dendritic water system located in tributaries for Hjuksån summer 2017 in northern Sweden. Seed samples were collected from three process domains (lake, rapids and slow-flowing) and later identified in lab. A greater species abundances and seed amount were found at lakes compared to rapids and slow-flowing reaches but there were no significant different between the process domains. None of the environmental factors showed to be important but there were indications that number of boulders might influence seed dispersal. Shannon Diversity index showed to be highest along slow-flowing reaches, but again no significant difference. Understanding process domains and their unique compositions in species abundance and diversity is for example an important factor for restoration techniques of anthropogenic modified streams.
