In 2022, food prices increased rapidly, prompting this investigation into how the price shock has impacted consumer behavior. Previous studies have found that price shocks affect low- income households with children the most. A switch to more calorie-dense food and a decreased consumption of snacks. This study aims to estimate the price elasticity of various food products and to identify how the elasticities differ among various types of households. The elasticities are calculated using OLS regression on receipt data from Coop. Results show that household variables, including income level, presence of children, shopping location, and organic product preferences, significantly impact the price elasticity of food products. Low-income households without children, living outside major cities and their suburbs, have a higher price elasticity, meaning these shoppers are more sensitive to price changes. The same tendencies were observed for all products even though the exact parameters could only be proven for a third of the products. The findings have important implications for understanding how price changes affect consumer behavior and can inform food policy decisions. / Under 2022 ökade livsmedelspriserna kraftigt, vilket inspirerade denna undersökning av hur prischocken har påverkat konsumenternas beteende. Tidigare studier visar att prischocker har störst påverkan på låginkomsthushåll med barn. Även en övergång till mer kaloririk mat och en minskad konsumption av snacks har observerats. Syftet med denna studie är att uppskatta priselasticiteten för olika livsmedel och identifiera hur elasticiteten skiljer sig åt mellan olika typer av hushåll. Elasticiteterna beräknas med hjälp av en OLS-regression på kvittodata från Coop. Resultaten visar att hushållsvariabler, inklusive inkomstnivå, barn i hushållet, varans inköpsplats och val av ekologiska produkter, påverkar priselasticiteten för livsmedel markant. Hushåll med låg inkomst utan barn, som bor utanför större städer och deras förorter, har en högre priselasticitet, vilket innebär att dessa kunder är mer priskänsliga. Samma tendenser observerades för alla produkter även om de exakta parametrarna endast kunde bevisas för en tredjedel av produkterna. Resultaten har viktiga implikationer för förståelsen av hur prisförändringar påverkar konsumentbeteenden och kan även informera livsmedelspolitiska beslut.

Syftet med denna undersökning var att belysa tre aktörsperspektiv på den kommande renoveringsvågen av GotlandsHems byggnadsbestånd: fastighetsägar-, kulturvård- och brukarperspektivet. Utifrån dessa perspektiv ville undersökningen identifiera målkonflikter samt nyansera och problematisera den rådande diskussionen kring kulturvärden i GotlandsHems bebyggelse från 1930–1975 samt sätta in renoveringsvågen av GotlandsHems bostadsbestånd i en större nationell och internationell kontext. Frågeställningarna inkluderade huruvida kulturvärden tar någon plats i diskussionen kring den kommande renoveringsvågen av GotlandsHems bostadsbestånd och vilka målkonflikter, mellan vilka aspekter, som gick att identifiera. Renoveringsvågen place- rades i en större kontext genom sitt ursprung i EU:s gröna giv och Sveriges nationella strategier. En fallstudie med tre kvalitativa intervjuer och en innehållsanalys genomfördes. Analysen identifierade fem teman: oro för hyreshöjningar, kommunikation, för- delar med energieffektivisering, återbruk och varsam renovering. I diskussionen identifierades fem målkonflikter mellan aspekterna hyresgäster, affärsmål, energieffektivisering och kulturvärden. Slutsatsen var att kulturvärden har diskuterats rikligt med flera olika infallsvinklar av alla aktörsperspektiv i denna undersökning. Diskussionen har däremot inte riktigt fått den plats som GotlandsHem borde ha gett den i förarbetet inför renoveringsvågen. En tidig utredning i renoveringsvågens projekteringsprocess av kulturvärden i GotlandsHems bostadsbestånd kommer göra avvägningar och konflikthantering mellan affärsmål, energieffektivisering, hyresgäster och kulturvärden enklare. / The purpose of this study was to highlight three perspectives on the upcoming renovation wave of GotlandsHem's building stock: the property owner, integrated conservation and user perspectives. The study wanted to identify goal conflicts as well as nuance and problematize the current discussion on cultural values in GotlandsHem's building stock from 1930-1975. From these perspectives it also aimed to place the renovation wave in a broader national and international context. The research questions included whether cultural values are considered in the discussions about GotlandsHem's upcoming renovations and which goal conflicts, between which aspects, that could be identified. The renovation wave was contextualized with a walkthrough of EU's Green Deal and Sweden's national strategies. A case study with three qualitative interviews and a content analysis was carried out. The analysis identified five themes: concerns about rent increases, communication, benefits of energy efficiency, reuse, and careful renovation. The discussion identified five goal conflicts between the aspect’s tenants, business goals, energy efficiency, and cultural values. The conclusion was that cultural values has been discussed abundantly with several different angles from all perspectives in this survey. However, the discussion has not really been given the place that Gotland- sHem should have given it in the preparatory work for the renovation wave. An early investigation in the renovation wave's planning process of cultural values in GotlandsHem's housing stock will make trade-offs and conflict management between business goals, energy efficiency, tenants and cultural values easier.

<p>Proučavane su koroziona postojanost i tendencija lepljenja različitih<br />materijala u kontaktu sa tečnom Al&ndash;Si&ndash;Cu legurom. Ispitivanjem su<br />obuhvaćeni čelik za rad na toplo, plazma nitrirani čelik i dupleks<br />slojevi sa CrN, TiAlN, TiAlSiN i CrAlN prevlakama, različitog nivoa<br />površinske hrapavosti. Za ispitivanja pomenutih fenomena<br />primenjena je metoda izvlačenja, koja je unapređena kako bi se povećale<br />njena tačnost i verodostojnost simulacije procesa livenja. Korozioni<br />efekti su pojačani tako što su uzorci osim kratkog kontakta sa odlivkom<br />zadržavani i u dužim periodima u kontaktu sa tečnom legurom (5 i 20<br />min). Uprkos opštim stavovima, za ispitivane materijale je<br />ustanovljeno da su sile izvlačenja uzoraka iz Al&ndash;Si&ndash;Cu odlivaka<br />nezavisne od njihovog hemijskog sastava. Uticaj hrapavosti je izražen<br />kod uzoraka sa prevlakama kod kojih pri smanjenju hrapavosti dolazi do<br />povećanja sile izvlačenja. Sve ispitane prevlake su sklone mehaničkom<br />lepljenju Al&ndash;Si&ndash;Cu legure za svoje površine, ali sa aspekta korozije u<br />tečnom metalu značajno prevazilaze performanse čelika i plazma<br />nitriranog sloja. Duži kontakt livene legure sa površinama prevlaka<br />uzrokovao je niže vrednosti sila izvlačenja, što je posledica<br />oksidacije površina prevlaka. Ustanovljeno je da su ispitivane<br />prevlake inertne ka tečnoj leguri aluminijuma. Međutim, dolazi do<br />oksidacije i korozije materijala podloge kroz greške rasta koje su<br />prisutne u prevlakama. Stečena znanja o identifikovanim<br />mehanizmima habanja i propadanja zaštitnih slojeva prevlaka<br />poslužiće daljem razvoju dupleks slojeva namenjenih za zaštitu alata<br />za livenje pod pritiskom.</p> / <p>Corrosion resistance and soldering tendency of different materials in molten<br />Al&ndash;Si&ndash;Cu alloy were studied. Hot-working tool steel, plasma nitrided steel and<br />duplex layers with CrN, TiAlN, TiAlSiN and CrAlN top coatings, which were<br />produced to various degree of surface roughness, were covered by the study.<br />An ejection test was employed for investigation of the concerned phenomena.<br />The ejection test was improved in order to increase its accuracy and the<br />reliability of process simulation. Samples were examined in both short and<br />extended periods of contact (5 and 20 min) with liquid casting. Casting<br />solidification was extended in order to intensify the corrosion effects. Contrary<br />to common findings, it was found that the ejection force of the investigated<br />materials does not depend on their chemical composition. For the coated<br />samples, a pronounced dependence of the ejection force on the surface<br />roughness was found. The ejection force increases with decrease in surface<br />roughness. All investigated coatings are prone to mechanical soldering by Al&ndash;<br />Si&ndash;Cu alloy. Still, their corrosion resistance substantially exceeds the corrosion<br />resistance of steel and plasma nitrided layer. Longer exposure of coated<br />samples to cast alloy induced lower ejection forces, which is a consequence<br />of coatings oxidation. It was found that the investigated coatings are inert to<br />liquid aluminium. However, the underlying material undergoes oxidation and<br />corrosion through coating growth defects. The findings concerning the wear<br />mechanisms of protective layers support further development of duplex layers<br />intended for die casting tools protection.</p>
