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. .

Optimization and validation of a triplex real-time PCR assay for thermotolerant Campylobacter species associated with foodborne disease

The genus Campylobacter is globally recognised as the leading bacterial cause of human foodborne gastroenteritis. Every year around 8000 Swedes are infected by Campylobacter. Most people are infected by thermotolerant Campylobacter species, commonly C. jejuni and C. coli.

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.

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.

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.

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.

-Villkorligt välkomna- En kvantitativ studie av civila integrationspolicys inverkan på immigrationen av icke EU-medborgare i Västeuropa

As scholars argue, there has been a rapid diffusion of civic integration policies in Western Europe the last decade. In the light of the debate about the extent of civic integration policies, recent studies have shown that the diffusion is limited to certain countries. Despite a flurry of literature based on civic integration policies, attention drawn to the implication of these policies has been quite inferior. This paper tries to examine what civic integration policies means in relation to immigration. Are civic integration policies used as an informal tool for the purpose of limiting certain groups of immigrants? I argue in this paper that the conditional factor in the civic integration policies creates a barrier for affected immigrants and their possibilities to gain long term residence.

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.

Antibiotic resistance associated with bacteria in irrigation water : a case study of irrigation ponds in Southern Sweden

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.
