    Medierna och Syrien: En kvalitativ innehållsanalys av tre globala mediers rapportering av Syrienkonflikten.2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I september 2015 anslöt sig Ryssland som en militär part till kriget i Syrien genom att börja bomba oppositionella styrkor. I samband med detta hamnade Ryssland och USA ännu en gång på motsatta sidor av en militär konflikt, Ryssland stödjer den syriska regimen, samtidigt som USA tillsammans med flera andra länder, däribland Qatar, stödjer oppositionen.

    Vi har valt att avgränsa oss till fem specifika händelser under den pågående Syrienkonflikten och tre mediers rapportering av dessa. Medierna som kommer att undersökas är USA- baserade CNN, Ryssland-baserade RT (f.d. Russia Today) och Qatar-baserade Al-Jazeera. Att undersöka dessa tre konkurrenter är intressant då dessa är bland de största medierna i världen och når därmed miljontals människor med sin information. Dessutom står länderna där medierna är baserade i på olika sidor av den väpnade konflikten. Syftet är att undersöka om rapporteringen har varit allsidig eller tendentiös. Dessutom ska uppsatsen undersöka om rapporteringen är opartisk eller propagandistisk. Artiklarna analyseras med hjälp av en av oss konstruerad undersökningsmodell, som tar avstamp i Lundgren, Ney & Thuréns massmedieretoriska analysmodell, och som kompletterats med kritiska frågor hämtade från Hermans och Chomskys teorier om kritik av internationell krigsrapportering samt kriterier hämtade från den svenske statsvetaren Jörgen Westerståhls forskning om objektivitet och opartiskhet i medierapporteringen.

    Resultatet av undersökningen visar att RTs och CNNs rapportering till stor del var tendentiös, och innehöll det som Herman & Chomsky kallar för propaganda på nästan alla punkter, samtidigt som de uppfyllde väldigt få av Westerståhls punkter för opartiskhet. Vanligast var att båda medierna hade en stor obalans i användningen av vilken part som får komma till tals. Den tendentiösa rapporteringen kan förklaras genom bristen på förstahandskällor, en stor mängd tendentiösa källor - men även hur CNN och RT finansieras. CNNs kommersiella syften, samt det faktum att RT finansieras av den ryska staten, kan vara faktorer som påverkar rapporteringen. Men Al-Jazeeras rapportering såg dock annorlunda ut. I undersökningen hittades inte en enda artikel där någon propagandapunkt uppnåddes, samtidigt som punkterna för opartisk rapportering till största del uppfylldes. Dessutom visades en helt annan allsidighet i rapporteringen från kanalen.

    Islam i religionsboken: Framställningen av islam och muslimer i två religionsböcker för gymnasiet2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The main objective of this research was to examine description of Islam in two different schoolbooks about religion. The rapport starts with an introduction of the subject and discusses the background of the topic. After the presentation, aims, and the questions I present my methods and material used in this research. Following the method and material is earlier research where I mention some of the previous rapports and results of researchers within the discourse. The theory used to investigate the text is postcolonial and the orientalism theory presented by Edward Said.

    The intention of the research was to answer if the books representation contributed to an oriental description of Islam and Muslims and to see how the text and pictures where used and structured. Similar researches have been presented earlier but this rapport handles a completely new book and a reedited book. The first book is written by Lars-Göran Alm and is called “Religionskunskap A” this book has been published before and is commonly used in schools all around Sweden. The other book is written by Olov Jansson and Linda Karlsson and is called “Religionskunskap A, en mosaik” and had its first release in 2009. The result shows that the book written by Alm represents a more oriental description and the text structure leaves the reader sometimes confused and wanting more. Alm chooses to bring up subjects like Islamism and circumcision of girls but both books mentioned a willingness of Shia Muslims to commit suicidal bombings. Alm left out more spiritual aspects like religious holidays and Sufism. The other book written by Jansson and Karlsson had some tendencies to an oriental description of Islam but not in the same extent as Alm. Jansson and Karlsson also gave a clearer representation of a Swedish context, which made the religion more present and not as distant as Alm. Both books used pictures to complement the text and in most cases in Alms book the pictures were images of places and persons in other continents and countries then Europe and Sweden.

    Föräldraengagemang, finns det olika sätt?: En studie om en grupp mödrars förhållningssätt till föräldraengagemang2013Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this qualitative study was to illustrate and analyze the approach and parental involvement of a group of mothers in their children's schooling. Also their reflections on parental involvement will be highlighted and what the parents experience as obstacles in their involvement.

    Method: I conducted six semi structured interviews for my research. I chose to interview six mothers who have a child in the sixth grade. I chose specifically the sixth grade because the mothers will have had quite a few contacts with the school at this point. I also chose not to reveal their ethnicity because they cannot represent a whole ethnic group anyway.

    Result: The result of my interviews show that the parents have different approaches when it comes to parental involvement. The approaches are different between the mothers but one thing they have in common is that they care about their children. 

    Conclusion: One of the conclusions of this study is that the parents who do not participate in meetings and activities at school, are either because of language barrier or lack of information concerning what the school expects of them. Furthermore the study shows that their lack of participation in school activities does not mean that they are not involved as parents. Instead they express their involvement in different ways, mainly in their homes.

    Får jag lov att vara annorlunda?: en vetenskaplig essä2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Min essä handlar om en händelse som är självupplevd. Den beskriver att det finns brist på erfarenhet om interkulturellt förhållningssätt på vissa förskolor. Den beskriver även att jag och mina kollegor inte kunde hantera några situationer som man i förskolans värld kan hamna i. Dilemmat som framträder i händelsen handlar om brist på kunskap när det gäller interaktion mellan olika kulturer. Detta speciellt på de institutioner där den är som allra viktigast i samhället, nämligen i skolans- och förskolans värld. Uppsatsen visar det förhållningssätt som pedagoger har gentemot vuxna och barn, som i pedagogernas ögon anses vara annorlunda.

    Det här är en vetenskaplig essäform där mina egna erfarenheter möter olika teoretiska perspektiv. På det sättet försöker jag att nå svar på mina frågor men även lyfta fram dilemmat i min essä. Därför får den som läser möjlighet att se mina erfarenheter ur nya perspektiv. Jag inleder min uppsats med att diskutera bristande interkulturellt ledarskap i förskolans miljö. Därefter utvecklas den med hjälp av teoretiska perspektiv, genom att lyfta fram hur vi kan bli bättre på att utveckla ett interkulturellt förhållningssätt. I mitt slutord reflekterar jag kring viktiga ämnen som essän har lyft fram med fokus på möjliga förbättringar. Det viktigaste ämnet i essän är det förhållningssätt som vi pedagoger har när det gäller barnens olikheter.

    Emotioner och marknadsföring: en studie om parfymannonser2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Reaching out with a specific message to consumers is the idea of marketing. Advertising is among the most common elements when it comes to marketing a product or a service. There are various ways to provide marketing with a message. A relatively new way that has become larger in marketing is to provide marketing with emotions. It has been shown in several studies that emotions can have a direct or an indirect effect such as ad-attitude and brand-attitude, and that is what our essay is about. This essay will make a research on perfume ads and see if the emotions in the ads have any connection to ad- and brand attitude.

    The research began with a preliminary study to make sure that correct ads were selected for the purpose of the main study, which was to gain a greater understanding of how we are positively affected by different emotions in perfume-ads and how it may affect different variables in the effect hierarchy, such as attitude toward the ad, attitude toward the brand and brand awareness. The method that was chosen for the study was quantitative. The main study contained 5 perfume ads where emotions, ad-attitude, brand-attitude and brand-awareness were measured.

    The results showed that emotions have a tendency to act as moderating variables when it comes to ad-attitude and brand-attitude. Depending on the design and conception of the ad, the results showed a stronger or weaker correlation between these variables.

    Hur stärks ett företags varumärke genom sponsring?: Rosa Bandet kampanjen2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this study is to analyze and investigate how a company’s brand is strengthened by the sponsorship and in which way. We will also make a comparison between a main sponsor and smaller sponsors.Method: We have used a qualitative method, i.e. interviews. We interviewed a sponsor charge by the three sponsors, we have chosen and a representative from the Pink Ribbon Campaign.Results and Conclusion: A company’s brand is strengthened by the sponsorship depending on what conditions the companies have. This means the strength of cooperation between donors and sponsor takers have. The more a sponsor helps the more space it takes, thus strengthening the brand more. The degree of strength depends on how appropriate the brand is in the A-ERIC model.

    Ungdomars berättelser om Hovsjö: En kvalitativ studie om hur sex ungdomar i åldrarna 21-26 ser på sitt bostadsområde2012Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background and problems: All that is stated in social media might not always sometimes be right, which has consequences for the individual's view of the described phenomena. The individual interprets and takes in mass media messages, which can lead to that the wrong information makes believed to be is correct one. The news media’s photo illustrations might pictures result in bad images of the suburbs. Hovsjö, residential area in the city of Södertälje, occurs in the media depicted as is a bad place to live due to the high rate of crime there.

    Purpose and Issues: My main research question is: How do young people view their residential area Hovsjö in comparison with the image they believe consider is given in that the news media gives the area? Further questions of the study are: How do the young people of the district describe their residential area? How do the youth's react to the news media images of Hovsjö? Has the neighborhood helped to form their identity?

    Method: In my data collection I have chosen a qualitative approach with observation and semistructured interviews. The reason I chose to do interviews is because it gives respondents the opportunity to give their own experiences and feelings of living in Hovsjö. My method has been ethnographic for the reason that I want to describe but also to understand the informants' world.

    Results: According to the interviews the news media has generalized Hovsjö as poor housing site pointing out mainly negative messages from the area. The informants have a different view on their residential area which does not correspond with the news media's version. They see their neighborhood in a positive way, and they explain that the environment has formed them to be good people. They do not deny the “crime incidents” in Hovsjö but they believe that the news media exaggerate events to depict the residential area as a criminal and dangerous area. As summary, I have come to a conclusion that the respondents have a positive view of their neighborhood which they consider a safe and a social area to live in.

    Socialt ansvar i ett svenskt företag: En studie om hur ett företag inom livsmedelsbranschen arbetar med CSR2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Numera engagerar sig allt fler företag i sociala och miljömässiga frågor då det förekommer ett krav från intressenter om att företag ska ta sådant ansvar. Fler företag involverar verksamheten i aktiviteter som berör Corporate social responsibility (CSR), för att tillfredsställa externa intressenter och uppnå en fördelaktigare position hos verksamhetens intressentgrupper.

    Problemdiskussion: Det förekommer en uppfattning om att företag enbart involverar verksamheten i frågor kring CSR i syfte att endast främja den egna verksamheten. Forskare menar att CSR aktiviteter inom ett företag kan ha en god inverkan på varumärket medan en del anser att effekten av dessa inte är uppenbara och tydliga.

    Frågeställning: Hur inkorporerat är CSR i Coops affärsidé och hur implementeras dessa hållbarhetsstrategier på butiksnivå?

    Syfte: Syftet med studien är att undersöka hur ett företag i Sverige arbetar med Corporate Social Responsibility (CSR). Vidare är syftet att undersöka hur företagets strategier inom CSR stärkt varumärket samt hur har resultatet av deras hållbarhetsstrategier gjort detta.

    Metod: Denna uppsats har utgått ifrån en kvalitativ ansats för att undersöka företaget Coop, där tillvägagångssättet delvis varit intervjuer med konsumenter och butikschefer samt företagets hållbarhetschef. Vidare har studien utgått ifrån sekundärdata för att analysera verksamheten genom relevanta teorier. Den teoretiska referensramen innehåller teorier om CSR av olika forskare samt Carrolls CSR pyramid. Vidare har den insamlade datan analyseras genom teoriernaom CSR, Carrolls Pyramid, Brand Identity, Brand Equity, Corporate Identity samt kommunikation av CSR.

    Slutsats: CSR är väl interagerat i Coops affärsidé framförallt på central nivå inom organisation. Dock har deras hållbarhets strategier inte stärkt varumärket enligt den empiriska undersökningen. Coop bör bli tydligare i sin kommunikation av sina hållbarhetsaktiviteter annars kommer detta inte att vara en avgörande faktor som stärker Coops varumärke.

    Klimatneutrala företag - kan IT minska utsläppen?2007Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    The attention on environmental issues has never been as huge as today. The climate is changing and more and more evidence suggest that the cause behind climate changes is an increase of carbondioxide into the atmosphere. The increase in turn is considerd to be an act of human activity. Therefore some companies have decided to become climate neutral and implement information technology in their business in order to reduce their emissions. This thesis has three aimes: to calculate a small company´s carbondioxide emissions, study whether or not information technology could help to reduce these emissions and furthermore find out why some companies decided to become climate neutral and describe the concept climate neutral. The results show that if information technology is used properly and effectively there are great potential to reduce the emissions, especially emissions from transportation sector. Now that the environment issues has become number one in the news and in the political agenda many companies try to cut their emissions, which is why some companies decided to take one step further and become climate neutral. Most of the companies see this action as a necessity in order to survive in a high competitive market. By doing so, they get more PR and more credit from both their investers and custumers. That is also why GreenIT´s carbondioxide emissions where calculated here. GreenIT have intentions in becoming climate neutral and in order to becoming one they have to reduce their remaining emissions by investing in projects in developing countries. As GreenIT is a small company they don´t have large emissions to reduce. This action will not cost them much but will probably give them an advantage in the market and credit from other investors and customers.

    Psykiskt sjukas utsatthet i medierna: En granskning av Svenska Dagbladets och Expressens rapportering om psykiskt sjuka2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Denna studie gick ut på att se om publiceringen av artiklarna som handlar om psykiskt sjuka och rättspsykiatri, ökade i omfång i Expressen och Svenska Dagbladet efter mordet på utrikesministern Anna Lindh den 10 september 2003. Vi ville även analysera några utvalda texter som tar upp psykiskt sjuka i samband med brott. Vi använde oss av både kvantitativa och kvalitativa metoder för att få en så heltäckande studie som möjligt. Det vi kom fram till är att artikelantalet i båda tidningarna ökade efter mordet på Anna Lindh. Dessutom såg vi en tendens till att Expressens artiklar är mer dramatiserande och innehåller fler och större bilder än Svenska Dagbladets artiklar.

    "Rollen på Scenen": En studie om vakters uppfattningar av den främre och bakre regionen2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study aims to obtain a deeper understanding of how the opinions of security guards differ between their professional and the private roles that they occupy. Furthermore the purpose is to find out how violence and threats prevent the performance of a successful guard role. The method we have used was qualitative semi-structured interviews with eight security guards. The result of the study suggests that the professional life and the personal life may form two separate spheres. The presence of threats and violence shapes a professional role where the internal cooperation is the main key.

    Motivation i läraryrket: En studie i vad som motiverar lågstadielärare och hur nya skolreformer påverkar deras motivation.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund - Enligt Statistiska centralbyrån kommer det saknas så mycket som 40 000 lärare inom de närmsta åren och det är endast fem procent av lärarna som anser att yrket är uppskattat av samhället. Med en utgångspunkt i svenska elevers försämrade resultat i internationella kunskapsmätningar och att detta i sin tur ses som ett resultat av den svenska skolans kunskaps- och disciplinproblem. Har man för att lösa dessa problem genomfört ett stort antal skolreformer och man har gjort en stor satsning på lärares professionella utveckling. Om dessa reformer påverkar lärares motivation är dock ett högst relevant men outforskat ämne.

    Syfte - Syftet med den här studien är att få djupare förståelse i vilka faktorer som motiverar lågstadielärare i sitt dagliga arbete och om dessa faktorer skiljer sig beroende på om de börjat arbeta innan eller efter implementeringen av de nya skolreformerna, samt studera hur skolreformerna, införandet av lärarlegitimation och den nya professionen förstelärare, som trätt i kraft de senaste fem åren har påverkat dem.

    Metod - Studien har en kvalitativ forskningsansats för att skapa en djupare förståelse över ett redan existerande fenomen. Som forskningsdesign används en komparativ studie tillsammans med semi-strukturerade intervjuer.

    Slutsats - Studien har visat på att det både finns skillnader och likheter mellan vad som motiverar lågstadielärare som har arbetat olika länge inom yrket. Alla som medverkade i den här studien ansåg först och främst att det var eleverna och att se dem lyckas som främst motiverade dem i deras yrke. Det som skilde grupperna åt var att de nya lärarna motiverades mer utav de yttre faktorerna, så som lön, vilket inte var lika viktigt för de gamla lärarnas motivation. Studien har även visat på att de nya skolreformerna inte påverkat lågstadielärare särskilt märkbart. Det råder dock delade meningar huruvida skolreformerna är av positiv eller negativ karaktär för lärarna.

    Determination of gp120 & Trx80 dependent production of hydrogen peroxide in cell free & cell-dependent systems2009Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Hydrogen peroxide (H2O2), a reactive oxygen specie (ROS), is most commonly associated with oxidative stress causing cytotoxic effects on living cells. Oxidative stress has been implicated in various conditions including neurodegenerative diseases, autoimmune diseases and cancer. In addition H2O2 is produced as a defense mechanism against pathogens, as being released by activated phagocytes. In recent years, H2O2 has become established as an important regulator of signal transduction in eukaryotic cells. Hydrogen peroxide is generated both intracellularly and extracellularly in response to various stimuli including cytokines and growth factors. There are different mechanisms by which H2O2 is generated, facilitating signal transduction in cells; through NOX-system in miyochondria, via singlet oxygen, receptor/ligand interaction or by redox active metal ions. The HIV glycoprotein 120 (gp120) is associated with HIV dementia and it is known as a neurotoxin that causes neuronal damage. It has been proposed that free radicals may be involved in the pathogenesis caused by gp120. In addition the truncated form of thioredoxin (Trx80) is known to stimulate HIV replication in HIV infected cells, however, the exact mechanism is not known. A possible way both proteins may mediate their activity is by inducing H2O2 production. The aim of this study was to investigate H2O2 production induced by the proteins gp120 and Trx80. In order to detect H2O2 production an assay based on the fluorescent compound Amplex Red, was established. The assay was used to detect H2O2 released by gp120 and Trx80 in a cell-free environment, in a cell-system and in the presence of metal ions (copper ions) with a physiological reductant (ascorbate). We did not detect H2O2 production induced by gp120 and Trx80 respectively, using our assay, however, other ROS such as hydroxyl radicals may have been generated although they were not detectable with our method. Hence, further studies are needed in order to fully understand how gp120 and Trx80 mediate their activity.

    Franchising: - Franchisetagarens möjligheter till förändring av varuutbudet.2007Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    Franchise is a form of cooperation between two merging parts: a franchisor and franchisee. In similarity to other businesses, it is important for a company based on franchising to adjust to the rapid market changes in order to achieve a competitive advantage of commodities. Due to the strict franchise agreement, the franchisees are restricted in adapting to the market changes. The purpose of this thesis is, therefore, to get an understanding of the franchisees perspective in their business, and also to see to what degree the commodities are affected by the control from the franchisor. We have chosen to limit the study to brand retail-stores in the fashion industry because of the rapid changes that distinguish it. Adjustment to changes in order to become more competitive is the point of weight in our thesis. We have also restricted us to Business Format Franchising. Casestudies was performed to fulfil the purpose of the thesis. The study consists of interviews with franchisees from three brand-retail stores in Stockholm. The selected brand retail-stores are part of the two corporations, namely, RNB and Bestseller. An interview with the vice president of the Swedish Franchise Association was also conducted. Based on our findings in the empirical material and analysis we have come to the conclusion that the franchise agreement is the central controlling force that allows the franchisor to control their franchisees business. There are indifferences between the two parts when it comes to the franchise agreement and when it comes to changes in the supply. It is obvious that it leads to a power struggle between those involved. The franchisee has undeniably small opportunities to effect merchandise supply, interior decorating and marketing. This is because the franchisor holds a firm hand around the basic concept which acts as an identity for the franchise line. Thus, there is a need from the franchisees to more free thinking outside the borders of the agreement, specially in the matter of adapting to customer requests. That is because they daily encounter consumer needs and has an overview of the trends on the market.

    Abstract [en]

    This essay deals with the influence of leadership on student use of Smart phones as an ICT tool at after school care. I use a qualitative, hermeneutical method that departs from two stories. I also use qualitative interviews with both structured and unstructured questions. My reflections and interpretations are, through the interviews, complemented by my colleagues’ views of the use of Smart phones and how that is affected by how the activities are managed. I have faced a dilemma in my stories where I have to choose between following the school’s rules or help the students that need help with the use of Smart phones.

    Reflecting on the stories leads me to view my own leadership and style of leadership in a critical light and to view myself in a wider context within a problematic organization with a hierarchical leadership. This leads to other dilemmas that occur in a school organization, where helpful factors to a change can be seen in different perspectives with the open dialogue as an advantage.

    I den monokroma gestaltens gryningsland: Representationen av icke-vita och vita i John Q2005Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Uppsatsens övergripande syfte är att utröna huruvida ett specifikt samtida populärkulturellt verk – den amerikanska filmen John Q (2002) – i representationen av sina karaktärer befäster en kolonialistisk diskurs eller om dessa gestaltas på ett sätt som skiljer sig från denna diskurs representationsmönster. Med kolonialistisk diskurs avser jag här en diskurs som fundamentalt gror ur de idémönster som var verksamma under den egentliga kolonialismen. Utifrån ett poststrukturalistiskt perspektiv med teoretiska analysinstrument från diskursteori och postkolonialism analyseras kvalitativt filmens karaktärer som indelas i fyra subjektspositioner; icke-vit man/kvinna och vit man/kvinna. Dessas identiteter undersöks i analysen utifrån fem huvudsakliga aspekter; 1/ funktion/roll i narrativet, 2/ personlighet och icke-fysiska egenskaper, 3/ agerande och förehavanden, 4/ utseende och slutligen 5/ eventuellt tydligt intertextuellt förhållande till den skådespelare som representerar honom/henne.

    Analysen visar att filmen John Q i upprättandet av en gynnad dikotomi mellan människa och system konstruerar karaktärernas identiteter på ett sätt som nästintill fullständigt följer den kolonialistiska diskursens representationsmönster. Icke-vita gestaltas på för diskursen typiskt stereotypa sätt och bland filmens vita karaktärer representeras de som intar en god narrativ roll i enlighet med den kolonialistiska diskursens vita ideal. Samtidigt tillskrivs de vita karaktärer som manifesterar en ond gestalt en systemidentitet som får funktion av förklaring till deras misslyckande att fullgöra vithet. Det fåtal försök till diskursiv förändring i vissa karaktärer undergrävs effektivt genom ett framhävande av andra aspekter i karaktären ifråga som gestaltas på för diskursen typiska sätt. Endast en karaktär skiljer sig härvidlag från de övriga och upptar en paradoxal och diskursivt icke-tillsluten position.

    Dagens hotellbransch: En studie som belyser hur hotell i Stockholm arbetar för att behålla sina gäster2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Because of the large supply of information is today's leisure travelers very enlightened and have firsthand knowledge of what can be demanded on a hotel stay. Along with business travelers, who are not price sensitive, they place higher demands on the standards and service they require. It has become increasingly important to attract the visitors in a unique way.

    The purpose of this study is to reveal those aspects which hotels focus on in their business in order to keep their guests, despite the strong competition and the new demands of the changing hotel industry. The study has examined more closely if the hotels have specific concepts in their approach, if their servicescapes (the environment where the service is assembled) are designed in a unique way to attract visitors and if the hotels have special relationships with their guests.

    The study is qualitative and in order to answer the purpose has observations of the selected hotels and interviews with managers and receptionists been made.

    One of the conclusions that we reached is that the most important aspect in the hotels business is their relationship to the guests. Each respective hotel strives to have a special and unique relationship with its guests conveyed by its staff. But even if the hotels have the same purpose, they use different ways to create a unique relationship to their guests. As for concept, we have concluded that none of the hotels work with thematisation, but that they instead use various concepts to make their guests' experiences more positive. The servicescapes are valued not quite high by the hotels, however, they are designed in different ways that convey certain emotions.

    Multirelaxation-time lattice Boltzmann model for droplet heating and evaporation under forced convection2015In: Physical Review E. Statistical, Nonlinear, and Soft Matter Physics, ISSN 1539-3755, E-ISSN 1550-2376, Vol. 91, no 4, article id 043012Article in journal (Refereed)
    Abstract [en]

    We investigate the evaporation of a droplet surrounded by superheated vapor with relative motion between phases. The evaporating droplet is a challenging process, as one must take into account the transport of mass, momentum, and heat. Here a lattice Boltzmann method is employed where phase change is controlled by a nonideal equation of state. First, numerical simulations are compared to the D-2 law for a vaporizing static droplet and good agreement is observed. Results are then presented for a droplet in a Lagrangian frame under a superheated vapor flow. Evaporation is described in terms of the temperature difference between liquid-vapor and the inertial forces. The internal liquid circulation driven by surface-shear stresses due to convection enhances the evaporation rate. Numerical simulations demonstrate that for higher Reynolds numbers, the dynamics of vaporization flux can be significantly affected, which may cause an oscillatory behavior on the droplet evaporation. The droplet-wake interaction and local mass flux are discussed in detail.

    Simulation of a suspended droplet under evaporation with Marangoni effects2016In: International Journal of Heat and Mass Transfer, ISSN 0017-9310, E-ISSN 1879-2189, Vol. 91, p. 853-860Article in journal (Refereed)
    Abstract [en]

    We investigate the Marangoni effects in a hexane droplet under evaporation and close to its critical point. A lattice Boltzmann model is used to perform 3D numerical simulations. In a first case, the droplet is placed in its own vapor and a temperature gradient is imposed. The droplet locomotion through the domain is observed, where the temperature differences across the surface is proportional to the droplet velocity and the Marangoni effect is confirmed. The droplet is then set under a forced convection condition. The results show that the Marangoni stresses play a major role in maintaining the internal circulation when the superheated vapor temperature is increased. Surprisingly, surface tension variations along the interface due to temperature change may affect heat transfer and internal circulation even for low Weber number. Other results and considerations regarding the droplet surface are also discussed.

    Droplet deformation and heat transfer in isotropic turbulence2017In: Journal of Fluid Mechanics, ISSN 0022-1120, E-ISSN 1469-7645, Vol. 820, p. 61-85Article in journal (Refereed)
    Abstract [en]

    The heat and mass transfer of deformable droplets in turbulent flows is crucial. to a wide range of applications, such as cloud dynamics and internal combustion engines. This study investigates a single droplet undergoing phase change in isotropic turbulence using numerical simulations with a hybrid lattice Boltzmann scheme. Phase separation is controlled by a non-ideal equation of state and density contrast is taken into consideration. Droplet deformation is caused by pressure and shear stress at the droplet interface. The statistics of thermodynamic variables are quantified and averaged over both the liquid and vapour phases. The occurrence of evaporation and condensation is correlated to temperature fluctuations, surface tension variation and turbulence intensity. The temporal spectra of droplet deformations are analysed and related to the droplet surface area. Different modes of oscillation are clearly identified from the deformation power spectrum for low Taylor Reynolds number Re, whereas nonlinearities are produced with the increase of Re A, as intermediate frequencies are seen to overlap. As an outcome, a continuous spectrum is observed, which shows a decrease in the power spectrum that scales as similar to f(-3) Correlations between the droplet Weber number, deformation parameter, fluctuations of the droplet volume and thermodynamic variables are also developed.

    Lattice Boltzmann Method for the evaporation of a suspended droplet2013In: Interfacial phenomena and heat transfer, ISSN 2167-857X, Vol. 1, no 3, p. 245-258Article in journal (Refereed)
    Abstract [en]

    In this paper we consider a thermal multiphase lattice Boltzmann method (LBM) to investigate the heating and vaporization of a suspended droplet. An important benefit from the LBM is that phase separation is generated spontaneously and jump conditions for heat and mass transfer are not imposed. We use double distribution functions in order to solve for momentum and energy equations. The force is incorporated via the exact difference method (EDM) scheme where different equations of state (EOS) are used, including the Peng-Robinson EOS. The equilibrium and boundary conditions are carefully studied. Results are presented for a hexane droplet set to evaporate in a superheated gas, for static condition and under gravitational effects. For the static droplet, the numerical simulations show that capillary pressure and the cooling effect at the interface play a major role. When the droplet is convected due to the gravitational field, the relative motion between the droplet and surrounding gas enhances the heat transfer. Evolution of density and temperature fields are illustrated in details.

    Thermodynamics of a real fluid near the critical point in numerical simulations of isotropic turbulence2016In: Physics of fluids, ISSN 1070-6631, E-ISSN 1089-7666, Vol. 28, no 12, article id 125105Article in journal (Refereed)
    Abstract [en]

    We investigate the behavior of a fluid near the critical point by using numerical simulations of weakly compressible three-dimensional isotropic turbulence. Much has been done for a turbulent flow with an ideal gas. The primary focus of this work is to analyze fluctuations of thermodynamic variables (pressure, density, and temperature) when a non-ideal Equation Of State (EOS) is considered. In order to do so, a hybrid lattice Boltzmann scheme is applied to solve the momentum and energy equations. Previously unreported phenomena are revealed as the temperature approaches the critical point. Fluctuations in pressure, density, and temperature increase, followed by changes in their respective probability density functions. Due to the non-linearity of the EOS, it is seen that variances of density and temperature and their respective covariance are equally important close to the critical point. Unlike the ideal EOS case, significant differences in the thermodynamic properties are also observed when the Reynolds number is increased. We also address issues related to the spectral behavior and scaling of density, pressure, temperature, and kinetic energy.

    Abstract [en]

    The aim of this essay is to examine the view on children with disability´s in the end of the 19 Th to the beginning of the 20 Th. We will examine the children that lived in Eugeniahememt but we will also examnie the view the society had on the children who lived on Egueniahemmet. In our essay there are four questions that we are going to answer.

    - Who took the initive to start Eugeniahemmet and how did it affect the activity?

    - Which view had the society on the children who lived on Eugeniahemmet?

    - How did the work with the children look like?

    - Which view had the staff, in Eugeniahemmet, on the children?

    The method that is being used in this essay is trying to analyses what the material tells us about the view on the children and how the work with the children lookt liked in Eugeniahemmet.

    The theory that we use is about Michel Focaults look on madness. Focault says that a person who is mad dosen’t have a connection between body and soul and that creates hallucinations witch leeds to madness. We also use a gender theory by Yvonne Hirdman who explains that women and men have diffrent roles in the society. Womens role is to be responsible for their home and the mens role is to be responsible for the public business.

    The main conclusion is that the view on children with disability in the society made it hard for Eugeniahememt staff to work whit the home´s activity. The view of the children in the society was that they were more a burden on the society than good citizen. These children was learned fast, but if the children who did´t learned fast were called idiot´s. Another coclusion is that in the beginning of Eugeniahemmet activity they accepted everyone even the children who consider be impossible to be educate. But in the beginning of the 20 Th they started to exlude the children who were impossible to educate, because they were idiot´s.

    ”Vi låter oss inte stoppas av andras kamp mot grundläggande demokratiska värden”: En narrativ analys av Sverigedemokraternas kriskommunikation efter Utöya2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper examines the communicative crisis defense of the Sweden democrats after the criticism that appeared after the mass murder by the right-wing extremist Anders Behring Breivik at Utöya in 2011. In this analysis a narrative examination is made of the party leader Åkessons explanation to why the crisis emerged and how his apology interacts with the party’s internal story. The first part of the results shows that Åkesson structures a narrative where the society’s witch hunt on the party stands as an explanation to why the crisis has emerged. The second part of the analysis shows that Åkesson uses the crisis to strengthen the role of the Sweden democrats as an anti-establishment party by using dichotomies. In his crisis narrative he attributes similar characteristics to his critics and Breivik. The consequence of this is that the two actors stand as a collective villain in the narrative. To the contrary, the Sweden democrats became a hero in the narrative - the protector of democracy in Sweden.

    Utan den andres bekräftelse är jag ingenting: En studie om kvinnan i kärleksrelationer och relationer2007Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    The aim of this essay is to analyse young peoples view and thoughts about women. I have studied how young people “create women” in an opinion poll about love relations and relationships.

    The survey has been answered by high school student in a suburb in Stockholm. My main question is: What conceptions of the women are presented in love relationships and relationships in general?

    To analyse the data, I have used a qualitative method which means that I have tried to understand and interpret their answers. The study consists of two surveys, one about love relationships and the other about empathy. The outcome of the study is presented as different women characters such as the shy women, the affectionate and the rescuing women, the bimbo and the object. The study shows that women and men are indeed a part of the construction of women.

    The study shows a pattern of words and actions that the young people connect to the female. It also shows that it is more accepted and expected for girls to write about feelings and pain. Young people seem to define themselves in a connection to the opposite by comparing

    themselves to the opposite sex. For example a woman who shows her feelings serves a purpose, the action is done in a way to be confirmed of the people around her, that she is a woman. Both boys and girls are a part of constructing women. They perform a pattern of

    actions that clearly shows the existents of norms; the effect of repeated actions is gender. It means that young people ‘look for’ actions that confirms there gender.

    The keywords in this study are young people, women, gender, love relationships/relationships.

    Finally I would like to thank my tutor Ana Graviz and the research group who has given support and help during the study and at the time of writing. And a big thanks to those who made this study possible, the class that participated in the study and their teacher.

    Anställningsform och stress: Hur upplever polisaspiranter sin anställningsform i relation till stress?2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper discusses and aims to give the reader a greater understanding of how police cadets experiencing stress in relation to their employment status and a gender perspective on male and female cadets experience different demands and expectations. As scientists, we will also study how aspirants handle stress and how they experience the benefit of the work. This is because the one who is rejected by the aspirant will lose all possibilities of becoming a police officer. The essay will primarily highlight the impact of employment status have on stress according to police cadets and how gender can affect the stress.

    During the research process, the researcher will have worked through qualitative semi-structured interviews with six respondents who work as police cadets. We have analyzed our material by Karasek and Theorell of requirements, control and support model that is about the extent of demand and control individuals have the work-related aspects. We also give examples of how the requirements and control support model works for police cadets in the field with the help of research addressing the topic. The other theoretical starting point is an occupational stress research of Kelloway, Hurrel & Days (2008). Data collection shows, and supported by our theory that the form of employment is creating concerns over future work, and that perceived stress is equal for both men and women.

    The aim of this study was to investigate, illuminate and discuss teacher’s and multilingual student’s view on the connection between their mother tongue and their learning of other languages. This qualitative study is based on interviews with eight students in the 8th grade and two language-teachers from the same school, as well as ethnographic observations during English and Swedish lessons. With the help of some relevant theories, the empirical study is compared, analyzed and interpreted. The results show that the theories and informant’s view on the connection between the mother tongue and other languages are similar, which is that the mother tongue must be fully established before a new language can be taken in.

    Multi-step dielectrophoresis for separation of particles2006In: Journal of Chromatography A, ISSN 0021-9673, E-ISSN 1873-3778, Vol. 1131, no 1-2, p. 261-266Article in journal (Refereed)
    Abstract [en]

    A new concept for separation of particles based on repetitive dielectrophoretic trapping and release in a flow system is proposed. Calculations using the finite element method have been performed to envision the particle behavior and the separation effectiveness of the proposed method. As a model system, polystyrene beads in deionized water and a micro-flow channel with arrays of interdigited electrodes have been used. Results show that the resolution increases as a direct function of the number of trap-and-release steps, and that a difference in size will have a larger influence on the separation than a difference in other dielectrophoretic properties. About 200 trap-and-release steps would be required to separate particles with a size difference of 0.2%. The enhanced separation power of dielectrophoresis with multiple steps could be of great importance, not only for fractionation of particles with small differences in size, but also for measuring changes in surface conductivity, or for separations based on combinations of difference in size and dielectric properties.

    One of the major applications for dielectrophoresis is selective trapping and fractionation of particles. If the surrounding medium is of low conductivity, the trapping force is high, but if the conductivity increases, the attraction decreases and may even become negative. However, high-conductivity media are essential when working with biological material such as living cells. In this paper, some basic calculations have been performed, and a model has been developed which employs both positive and negative dielectrophoresis in a channel with interdigitated electrodes. The finite element method was utilized to predict the trajectories of Escherichia coli bacteria in the superpositioned electrical fields. It is shown that a drastic improvement of trapping efficiency can be obtained in this way, when a high conductivity medium is employed.

    Är sportjournalistiken offside?: En studie om framställningen av manliga och kvinnliga fotbollsspelare inom den svenska sportjournalistiken2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här kandidatuppsatsen granskar fördelningen av utrymmet på sportsidorna utifrån könstillhörighet. Vi undersöker hur mycket utrymme som tilldelas herrarnas respektive damernas slutspelsperioder under Europamästerskapen i fotboll år 2012, 2013, 2016 samt 2017 i Dagens Nyheter, Aftonbladet och Expressen. Vidare undersöker vi om det förekommer skillnader i rapporteringen om manliga respektive kvinnliga fotbollsspelare i Dagens Nyheter och Expressen år 2016 och 2017. Slutligen diskuterar vi frågan gällande på vilket sätt Dagens Nyheters och Expressens rapportering under slutspelen i fotbolls-EM år 2016 och 2017 bidrar till att upprätthålla de etablerade könsrollsuppfattningarna.

    Uppsatsen utgår från ett genusperspektiv och redogör för en del av den tidigare forskning som finns inom området genus. För att besvara frågeställningarna används kvantitativ innehållsanalys samt kvalitativ diskursanalys. Resultatet av vår kvantitativa analys är att herrarnas mästerskap värderades högre ur ett nyhetsvärderingsperspektiv och tilldelades mer utrymme än damernas mästerskap. Den kvalitativa diskursanalysen visar att det under herrarnas mästerskapsår rapporteras om enbart män, medan det under damernas år rapporteras om båda könen. Den kvalitativa analysen visar därmed att männen tilldelas mer plats i medierna än kvinnorna. Detta överensstämmer med resultatet av vår kvantitativa analys, samt den tidigare forskning som lyfts fram i vår studie. Slutsatsen är att herrarna är överrepresenterade på sportsidorna samt att medierna upprätthåller de etablerade könsrollsuppfattningarna.

    Is A Holistic Approach Relevant for Non-Governmental Organizations’ Agricultural Extension Strategies?: Case Studies from Tanzania2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Agricultural extension can play a major part in the development and adoption of sustainable agriculture practices. Local NGOs have a unique opportunity to serve as extension agents due to their acceptance and close relationship in communities. The paper argues that agricultural extension needs to adopt a holistic approach to the communities’ development to achieve a lasting and sustainable agriculture. This study examines four NGOs in Tanzania to see 1) how they provide extension services; 2) if they have a holistic approach; and 3) if the holistic approach is a conscious strategy. The findings show that a mixture of extension methods is commonly used by all four of the NGOs. More over the NGOs offer a wide variety of projects, which focus on different issues. This results in a holistic approach, even though this probably is rather a result of funding practices than a conscious extension strategy.

    Facebook: En intervjustudie om utformandet av Narcissismens kultur på nätverk2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The goal with this paper is to examine and analyze the way that the youth look at their use of Facebook. A survey was conducted on 10 high school students in Stockholm to review if Facebook reveal narcissistic behavior. To explain this, we gathered information about narcissistic culture, weak band strength, symbolic interactionism and the dramaturgical perspective. To our conclusion, the narcissism dominates on the social network level, as result of their attitudes and view of other members.

    Passa pucken eller inte?: En kvalitativ studie om maktrelationen mellan hockeyjournalister och citizen journalists2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna uppsats är att undersöka hur makt konstrueras inom hockeyinformationsflödet på Twitter. Genom att ta utgångspunkt i hockeyjournalisters utsagor är målet med uppsatsen att belysa rådande maktstrukturer mellan journalister och citizen journalists på Twitter. Jag vill även undersöka hur nya informationsteknologier har förändrat journalisternas yrkesroll och yrkespraktik, med ett stort fokus på den förändrade interaktionen med de olika typerna av användare (journalister, citizen journalists och ”vanliga” medieanvändare). För att ta reda på detta har uppsatsen analyserat relationen mellan citizen journalists och journalister ur ett maktperspektiv. För att undersöka hur makt konstrueras inom Twitter har jag utgått ifrån Manuel Castells diskussion kring makt och värdeskapande i nätverkssamhället. Jag har även valt att använda journalistikens ideologi och praktik i förändring samt citizen journalists och dess förhållande med journalister som teoretiska utgångspunkter för att undersöka hur nya informationsteknologier och den förändrade interaktionen med användarna har påverkat journalisternas yrkesroll och yrkespraktik. Genom kvalitativa forskningsintervjuer med fem hockeyjournalister på rikstäckande mediebolag visar de resultat jag fått fram att det har skett en maktförskjutning mellan citizen journalists och hockeyjournalisterna. Relationen verkar utåt sätt präglas av en demokratisk dialog och större informationsutväxling de två emellan, men hockeyjournalisterna verkar fortfarande befästa makt kring nyhetsprocessen genom att referera till den journalistiska ideologin. Detta gör att det fortfarande finns en tydlig hierarkisk ställning inom hockeyinformationsflödet. Resultatet visade även att hockeyjournalisternas yrkespraktik präglas av en mycket högre hastighet än tidigare vilket har förändrat journalisternas sociala praktik, där det stora informationsflödet har omvandlat deras tillvägagångssätt att hämta och distribuera nyheter och information. Till skillnad från vad andra studier visat så pekar min studie på att hockeyjournalisternas yrkesroll blivit mer individualiserad, med högre krav på tekniskt kunnande och kunskaper inom flera olika medieområden till följd av en mer krävande och kunnig publik.

    En studie om användandet av årsredovisningen vid bostadsrättsköp2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Find out how and in what way buyers of housing co-operatives use the association ́s annual report in their purchase decision and investigate whether they understand it or not.

    Method: The study is conducted using a qualitative method in the form of interviews. The Authors stood outside viewings and interviewed presumptive buyers of housing co-operatives in Stockholm.

    Empiricism: The study was conducted on 22 respondents, all interviewed outside a total of six different viewings around Stockholm. It turned out that the majority of respondents did not fully understood annual reports and most of them asked for help. The majority of those who felt they understood the annual report also asked someone in their surroundings to help them determine the stability of the housing association's economy. The result showed that homeowners usually use the annual report to see "warning signs" that indicate that a association will raise its fees. To evaluate the association ́s economy, most of the respondents used indebtness.

    Analysis: The study points out that since many homeowners did not fully understood the annual report, it could be difficult for them to make decisions based on it. This has been linked to previous research that highlighted similar problems. There are similarities between the improvement and change proposals developed by FAR together with other organizations and the results the study has shown.

    Conclusion: Presumptive buyers of housing-cooperatives generally do not understand annual reports so well that they can make a financial decision based on it. At the same time, the study has shown that even those homeowners who felt they understood asked for further help and advice from their surroundings. The study's conclusions are that there is a great deal of room for changing the accounting for housing co-opratives associations to make them more

    transparent and understandable to it ́s users. Furthermore, it was concluded that regardless of the individual's understanding of an annual report, he largely takes advantage of his surroundings as it is a major and comprehensive decision.

    En slumpmässig vandring eller genomsnittlig återgång: Råder förutsägbarhet på Stockholmsbörsen?2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study has been conducted in order to determine the existence of predictability for the Stockholm stock exchange. With this purpose the random walk theory has been raised against the theory of mean reversion in order to determine which theory is the most substantial. Data has been collected from Nasdaq OMX Nordic and furtherly been processed using the statistical software EViews. Swedish listed companies’ daily share values between 2000-2014 have been analyzed using two tests; an Augmented Dickey Fuller test and a Variance Ratio test. The results show generally that the null hypothesis - and thus the random walk - is rejected in the short term. This means that both on an aggregated level and on an individual level, the Stockholm stock exchange is predictable in the short term - in the form of mean reversion - and that it is most evident in small cap firms.

    Agencies towards Sustainable Development – A Study of Environmental Management Systems in Governmental Agencies 2005

    A vision of the Swedish government is to build an ecologically sustainable society. A tool in this effort is to implement environmental management systems (EMS). The aim of the thesis is to present in which phase of the implementation of EMS Swedish governmental agencies are. This will be done by compilation and evaluation of agencies’ yearly environmental reports.

    The thesis is written in co-operation with the Swedish Environmental Protection Agency (Swedish EPA). Swedish EPA has the responsibility to coordinate and drive forward the development of environmental management systems. The thesis is therefore a scientific tool to evaluate how the government’s decision, that governmental agencies have to implement an EMS, is fulfilled.

    Keywords: Sustainable development, environmental management systems, governmental agencies, environmental report.
