Spinn i det nya medielandskapet : Nya medieaktörers inflytande på den traditionella journalistiken

Aim With this study we want to highlight and analyze the media spin of the PR campaign Miss Skinny by clarifying; a diffusion pattern which covers posts published by bloggers and journalists; a framing pattern from the first audited post to the last; how journalists are influenced by user generated content, and what consequences this may have for the news coverage.Method We have conducted a studied of news posts and blog posts about the Swedish PR campaign Miss Skinny through content analysis, diffusion analysis and mapped direct links between blog posts and news posts.Main result We found that a surprisingly large amount of news postings contained direct links to previous blog posts and that the former media serial no longer can be applied on today's modern media where journalists and other players come together on the converged media arena. .

På spaning efter drivkrafter och rötter: En motivanalys av drivkrafter inom Sveriges Pensionärers Intresseparti samt om inspirationskällor vid partiets uppkomst

One aim of this thesis has been to trace the driving forces among active members of the Swedish Pensioners? Interest Party (SPI), but also to render how party values and ideas are connected to the concepts of is-sue space, distrust, and New Party Politics (mainly populism). Since there are several pensioners? parties in other countries, my second aim has been to investigate whether the party is a result of a diffusion proc-ess of copying a successful equivalent party; in other words to find out whether a master frame has inspired the forming of a Swedish pension-ers? party. Through interviews and document analysis, I have found seven issue dimensions explaining the motives behind my respondents? engagement in the party.

Reducering av DOC beroende av karaktär med fyra dricksvattenberedningstekniker : Jämförelse mellan fällning (FeCl3 och Al2(SO4)3), membranfiltrering och jonbyte med MIEX®

Halten löst organiskt material (DOC) har under de senaste 20 åren ökat i våra sjöar. Det har också skett förändringar i karaktären. DOC ställer till problem för vattenverk som använder ytvatten som dricksvattenkälla genom att det kan ge lukt, smak och färg till vattnet. Det ger också ett ökat behov av fällningskemikalier, större slambildning och större bildning av potentiellt skadliga desinfektionsprodukter. I och med förändringarna i halt och karaktär av DOC behöver nuvarande reningstekniker förbättras och nya tekniker utvecklas.I den här studien undersöktes två konventionella reningstekniker; fällning med järnklorid och fällning med aluminiumsulfat, samt två modernare tekniker; jonbyte med MIEX® och membranteknik.

När tar man fram kondomen? : En studie om lärares attityder till UR och RFSU:s projekt för en bättre sexualundervisning

The debate in the media on a new Swedish sex education movie sparked our interest in this study. The twenty-eight minutes long movie ?Sex on the map? is the first of it?s kind in twenty-five years. It is also part of a bigger sex educational project that contains, apart from the movie, a book about sex education, a documentary and a teachers guide. The project is a co-production between the Swedish Educational Broadcasting Company (UR) and the Swedish Association for Sexuality Education (RFSU).We were interested in how teachers received information about the project, and what their attitudes were towards it.

Specifik omvårdnad under ambulanstransport vid hjärtinfarkt-Jämförande studie mellan kvinnor och män

Studie av koldioxidgradienter i havets ytskiktSofia SöderholmDenna studie bygger på ett nyligen utvecklat instrument som har mätt koldioxidkoncentrationer på tre olika djup i vattnet samt en nivå i luften. Då detta instrument var oprövat i vatten har en utvärdering av mätmetodens lämplighet för vattenmätningar utförts. Syftet med mätningarna var att undersöka ytvattnets vertikala koldioxidgradient för att med hjälp av denna kunna beskriva flödet av koldioxid mellan hav och atmosfär bättre. Detta flöde är en viktig del av den globala kolcykeln och en djupare förståelse för koldioxidflödets beteende kan i framtiden bidra till mer noggranna klimatprognoser. Hur de beräknade flödena från profilinstrumentet påverkas av temperaturgradienterna i vattnets ytskikt har även det studerats.

I förändringens spår En undersökning av referensbibliotekariers accepterande av tillgängliggörandet och användandet av databaser på och via folkbibliotek

In Sweden most public libraries give users access to databases. These databases are sometimes possible to reach outside the library by internet at any time and this provides a change for the library and the society. Librarians function as change agents when they give access to databases and when databases are introduced to users. However, reports show that the use of databases, especially those in English, is not high in reference work. This study aims at analysing attitudes of librarians to access and use of databases on and by public libraries.

Koncentrisk hämning och stimulans av bakterietillväxt i agarkulturer

The aim of this study is to elucidate factors that effect growth of Sarcina lutea and Bacillus subtilis, exposed to the growth inhibitor SDS (Sodiumdodecylsulfat). Agar diffusion experiments revealed repeated, concentric zones of inhibition and stimulation upon exposure to Sodiumdodecylsulphate or to Amoxicillin. Temperature, nutrient concentration and inhibitor concentration were controlled. Formation of successively repeated zones of inhibition, stimulation, inhibition and stimulation is discussed: ? The extension of the primary inhibition zone is due to the concentration of applied Sodium dodecyl sulphate.? Immediately outside the primary inhibition zone the bacteria have access to diffusing nutrients that have not been consumed in the primary inhabitation zone.? In zones of dense bacterial growth the bacteria may produce inhibiting substances, affecting growth of bacteria in adjacent zones.? In zones of dense bacterial growth the nutrients will soon become depleted, thus affecting bacteria in adjacent zones..

Ledning av komplexa projekt : Det nationella införandet av Pascal ordinationsverktyg i hälso- och sjukvården

Det ökande behovet av nationella IT-stöd inom hälso- och sjukvård har lett till att en nationell IT-strategi för vård och omsorg har utarbetats och att flera projekt inom ramen för denna strategi har startats. Ett av dessa projekt är utvecklingen och det nationella införandet av det nya ordinationsverktyget Pascal vilket innefattar samtliga landsting och kommuner. Förutsättningarna för projektet och dess storlek medför att ledningen måste finna tillämpbara strategier för att hantera dess komplexa förhållanden. Det har konstaterats att ett stort antal projektmisslyckanden kan bero på att komplexa projekt leds genom icke tillämpbara strategier. Ledning av komplexa projekt försvåras av det faktum att linjära strategier inte är tillämpbara, strategierna bör istället situationsanpassas och väljas efter de olika problemen som måste bemötas under projektets gång.Denna fallstudie ämnar identifiera vilka komplexiteter projektet uppvisar samt hur de kan hanteras utifrån projektets förutsättningar.

Implementering av Virtuellt Byggande i byggprocessen : Fallstudie av NCC Construction Sverige AB

Virtual Design and Construction (VDC) is the definition for using BIM in the construction process to simulate and analyse the building. Resulting use of the technology will according to proponents lead to fewer construction errors, a better understanding between stakeholders for the construction project, less communication problems and a smoother construction process. Although BIM has according to researchers a big potential, few companies have succeeded in broad and continues implementation. The study aims to identify the factors affecting the implementation. More precisely identify what factors influencing the decision to adopt VDC and potential barriers in the diffusion process. The empirical findings are based on a case study of NCC Construction Sweden.

Nätverkskommunikation för jämställdhet

AbstractTitle: Network communication for equal opportunities (Nätverkskommunikation för jämställdhet)Number of pages: 47 (54 with enclosures)Author: Hillevi GoodTutor: Ylva EkströmCourse: Media and Communication Studies DPeriod: Spring Semester 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The aim of this essay is to study the possibilities to bring about change by the means of communication in two networks, focusing on the implementation of the Swedish Equal Opportunities Act.Material and method: The study draws on data collected in an electronic survey among representatives of two networks consisting of representatives from trade unions and employer?s associations. The material is analyzed using descriptive tools, cross tables and correlation matrices in which general characteristics as well as individual understandings of the network communication are presented and discussed.Main results: The general results indicate that the network communication serves important purposes, such as providing support and motivation for the members and changing attitudes towards equal opportunities. The analysis suggests that the network members have good communicative possibilities to serve as agents of change within their organisations. Moreover, there is an observed relation between, on the one hand, organizational context and, on the other hand, the network members? own communicational behaviour and their experienced possibility to influence their organizations.Keywords: network communication, diffusion of innovations, behaviour change, Equal Opportunities Act.

Hoppa på tåget eller stå kvar vid stationen? : Organisationers användning av sociala medier

Purpose:The purpose of this paper is to investigate and clarify some of the factors that influence organizations to adopt or reject the social media, and if the emergence of social media influenced the organization's communication.Metohodology:A qualitative methodology has been used to execute the study. The source has been semi structured interviews with chosen representatives from several organizations.Theoretical perspective:The theoretical basis for the execution of the methodology is based on the provisional theoretical demarcation uses and gratifications theory. For analysis diffusion of innovations theory is applied.Emperical findings:The empirical material includes interviews with representatives from twelve selected organizations, defined as companies in the industry and authorities, in seven different industries.Conclusion: The main factors affecting an adoption of social media is the organization?s open structure, the ability to see opportunities with social media and that they are seen as a natural part of development in the communications field. The main factors affecting a rejection of social media is ignorance, the organization's governance and that there must be a need that social media can fill.

The diffusion of minimum tillage in agricultural China : a study of the factors influencing the farmers? choice of tillage system

The Chinese government´s aim to be self-sufficient in food production in combination with the increased food consumption in China has put high pressure on the productivity within the Chinese agricultural sector (He j et al, 2010). In order to increase the productivity, modernization and adoption of new farming techniques are essential. The opportunity to adopt and import foreign technology has lately been possible in China, as more authority and decision rights have been given to the individual farmers and the country has opened up for foreign trade (Zheng, 2012 & Fan, 1991). A more open Chinese market enables new opportunities for foreign agricultural companies to expand their businesses by introducing their products to Chinese farmers. But to succeed with this strategy the Chinese farmers must be willing to adopt these, for them new innovations. Minimum tillage is a tillage practice used worldwide that is suitable in northern China where drought and erosion are the main problems in the crop production (pers.com., Arvidsson, 2012). Potential users? opinion of new innovations such as minimum tillage is closely related to adoption (Rogers, 2003).

?Det är trevligt att bläddra?? : om anledningar till varför man läser papperstidningar

Purpose/Aim: To investigate why people in the age group of 30-40 subscribe to the traditional morning newspaper even though they can get the same information at a much lower cost from for example TV, the internet or the free daily papers. The aim is to also look at possible future alternatives to the traditional morning newspaper.Material/Method: Focus group interviews were used to gather the empirical material. These consisted of a total number of twelve people, divided into three groups. The results from the focus group interviews were analysed with help from established uses & gratifications theories and two diffusion theories.Main results: This study shows that people read the traditional morning newspaper to get a good mixture of entertainment and local, national and global news. It is relaxing to read the newpaper on paper compared to reading it on the internet, mainly because you get a good overview which makes it a lot easier to find exactly want you want to read.
