To share belongings between friends is a common phenomenon. However, sharing as a business trend or even an economic system, in which unfamiliar individuals share assets and skills via online platforms, usually for a fee, is a newer phenomenon. The economic system is generally called “the sharing economy” or “collaborative consumption”. Characteristic for companies involved within the sharing econ
Hur ska radikalisering förstås och bekämpas? Grundläggande för all problemlösning är att problemet är korrekt definierat. Så är inte fallet i frågan om våldsbejakande extremism. Uppsatsen argumenterar för att det grundläggande problemet är att ideologin som faktor är negligerad. Syftet är att beskriva komplexiteten i fenomenet radikalisering och att bidra till diskussionen om åtgärdsalternativ gen
In this master’s thesis I examine two discursive figures that have especially caught my attention in media texts, and that I have found are closely connected to each other. I call them childhood libraries and childhood reading experiences. In this thesis I study how childhood is working performatively and rhetorically together with library and reading in the discursive figures, and in what way the
Ichthyosaurierna (fisködlorna) är en grupp marina reptiler som levde under mesozoikum. De är alla inkluderade i överordningen Ichthyopterygia som består av minst 36 släkten och 80 arter. De tidigaste formerna förekommer i sediment avsatta under etagen olenek i äldre trias (dvs. för ca 250 miljoner år sedan), och de sista fisködlorna dog ut under cenoman i slutet av krita, (dvs. för ca 90 miljoner Ichthyosaurs (‘fish lizards’) are a group of marine reptiles that lived during the Mesozoic Era. They are all included in the superorder Ichthyopterygia, which consists of at least 36 genera and 80 species. The earliest ichthyosaurs occur in sediments deposited during the Olenekian in the Early Triassic (about 250 million years ago), and the last forms became extinct during the Cenoman in the Late
Pre-mixed nitromethane/air/nitrogen flames on a heat-flux burner are investigated at atmospheric pressure with equivalence ratios of =0.8 and =1.2. Flame thermometry and chemiluminescence spectrum were used to characterise the flame before carrying out saturated laser induced fluorescence on NO molecules. The temperature profile revealed three zones of nitromethane combustion with maximum temperat
Att drabbas av en kritisk sjukdom och vårdas på intensivvårdsavdelning är en traumatisk upplevelse som både patient och anhöriga bär med sig under lång tid. Denna studie utgår från ett patientperspektiv där individens subjektiva upplevelse studeras. Syftet var att belysa intensivvårdspatienters upplevelser av återhämtning efter utskrivning från sjukhuset. En kvalitativ intervjustudie genomfördes o
This thesis is about how social movements write history. Sooner or later most social movements decide to write their own history, even though this is in no way included in their original ambition. Why is that, and what can we learn from it? To make this study possible I have chosen to study the labour movement in Sweden, and its two biggest archives, the ones in Stockholm and Malmö. The periodical
Faro- och riskidentifiering i råvatten - förbises alarmerande miljögifter? I ett land som Sverige borde man kunna känna sig trygg med att myndigheter och dricksvattenproducenter uppbjudit alla krafter för att garantera ett rent dricksvatten. Av denna studie verkar det som att så inte är fallet och att systemet som ska förebygga miljögifter i dricksvatten är för ostrukturerat och oprioriterat. MeThis study examines drinking water producer’s performance of hazard and risk analyses and how they take emerging chemicals into account. The high-profile cases in 2011-2013 with PFOS contaminating drinking water in Kallinge, Botkyrka and Uppsala highlighted the problem of emerging chemicals in sources of drinking water. Through literature study and analysis of performed hazard and risk analyses fr
The purpose of this study is to examine digital information loss at three Swedish archives. Digital preservation is a complex issue and something most archival institutions struggle with today. While there is merit in focussing on successes in this struggle, doing so to the exclusion of failures runs the risk of creating a blind spot for existing problems. We hope that this study will contribute t
Several digital technologies are now available to record and document archaeological excavations. A large number of studies have been published concerning the use of laser scanning, image based 3D modelling and GIS. By integrating different typologies of 3D data from Uppåkra, an Iron Age central place in southern Sweden, this thesis focuses on the development and evaluation of how 3D Geographic In
Denna studie anlägger ett diskurs- och fältteoretiskt perspektiv i syfte att förstå hur offentliga organisationer hanterar spänningen mellan deras till synes oundvikliga interna motsättningar och ambitionen att integrera kommunikationen. Malmö stads samordning i syfte att tala med en röst i relation till det så kallade ”Sorgenfrilägret” studerades som fall. Administrativa tjänstemän och lokalpolitDrawing upon discourse and field theory, this study sets out to understand how public organisations manage the tension between inherent internal contradictions and the ambition to integrate their communications. Malmö city’s work coordi-nating the city’s communication in relation to the so called ‘Sorgenfri camp’ was studied as a case. Administrative employees and local politicians involved with t
During steady state, the intestinal immune system functions to maintain the bowel’s physiological function in the face of constant bombardment by environmental materials (potentially infectious agents, commensal bacteria and foreign proteins). Immune responses thus maintain a delicate balance between immunogenicity against harmful invading pathogens and tolerance of the harmless diet and commensal
Femtosecond pulse shaping is a versatile tool that enables the generation of ultrashort laser pulses with nearly arbitrary temporal shapes. Among others, the technique is of use in ultrafast spectroscopy experiments where it can be employed for dispersion control and the generation of well-defined laser pulse sequences. In this work, a Fourier-transform pulse shaper based on a pixelated liquid crys
This paper investigates the linkages between stock markets of the United States and the Greater China Economic Area including China mainland, Hong Kong and Taiwan. In order to find the effects of the 2008 global financial crisis, we use the weekly stock market indices of Standard and Poor’s 500, Dow Jones China 88, Hang Seng and Taiwan Stock Exchange Weighted for each stock market from January, 20
This master’s thesis is a discourse analysis of a media debate, which mainly took place in the summer of 2015, concerning disturbing situations caused by patrons in public libraries. In the early stages of the debate a lot of attention was spent on defining the patrons causing violent and threatening situations towards librarians and other patrons. Soon the media debate also came to focus on what
This thesis investigates the determinants of tax morale by assessing different channels of tax morale identified in the previous literature. Survey data from the World Values Survey and the European Values Study is combined, and complemented by aggregated data on governance, tax burden and GDP per capita. The data is analysed primarily using ordered probit estimation. Several other estimation meth
Bostäder och lokaler utgör 39 % av Sveriges totala energiomsättning. Enligt EU-direktiv; ”Direktivet om Energieffektivisering”, 2012/27/EU ska energiomsättningen i fastigheter minska med 20 % fram till år 2020. För att detta mål ska kunna nås behöver befintliga fastigheter och nyproduktion börja energioptimeras. I befintliga byggnader görs detta genom en energikartläggning följt av en energieffektToday, residential and facilities represents 39 % of Sweden’s total energy turnover. According to EU directives; "The Directive on Energy Efficiency", 2012/27 / EU the energy turnover shall decrease by 20 % until 2020. To achieve this goal, the existing properties and new construction need to be energy optimized. In existing buildings this is done by an energy audit followed by energy ef
