Extra! Extra! En studie i urval och nyhetsvärdering av push-notiser

This case study aims to find out whether the promotion of Swedish news through push technology, and the selection process behind it, obeys the traditional criteria of news values.A months-worth of push notifications, sent out by the mobile phone applications of newspapers Dagens Nyheter and Expressen, were analysed through the application of a number of taxonomies meant to determine their newsworthiness.These taxonomies were, however, based on 20th century media, and do not necessarily adapt well to analysis of digital news publication forms. The purpose of this study is therefore to find out which criteria are still relevant to the news selection behind a digitalformat such as push notifications; and which have become obsolete.The basis of this study is the criteria of news values originally designed by Galtung and Ruge in 1965 and revised by Harcup and O?Neill in 2001; as well as the model of assessing front page news proposed by Hvitfelt. The content analysis was conducted in a manner as similar to that of Harcup and O?Neill?s own study as possible, so as to constitute a re-revisal ?revamped for the digital age.Our results show that the criterion of ?frequency? ? that is the conformance between the time-span of an event and the publication frequency of a medium ? has acquired an ambiguous importance.

Uppamma mod och utjämna makt : Ett aktionsforskningsprojekt där arbetsredskap utformades tillsammans med sjuksköterskestudenter för att kunna lindra för personer att leva med ovisshet.

Uncertainty is a well-known phenomenon that is recurring in biographies, imaginative literature and science, but is less studied in nursing science. The aim of this participatory action research project was to, in collaboration with nursing students; explore nursing activities for relieving patients? uncertainty. A qualitative approach was chosen with focus groups and the text was content analyzed. The students studied their third semester on a nursing program.

Uppgradering av biogas med aska från trädbränslen

The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

Hur kommer barn till tals i domen?

The purpose of this essay was to see how the child's voice was being heard in the verdicts in trials. I looked into court cases where parents wanted custody of their child/children. The focus of my analysis was on how the verdicts were presented and if the child/children were described in the court cases. The method that I used was qualitative documentanalysis. I chose seven court cases to investigate and analyse.I described theories of Foucault's power to get a different perspective on courtroom cases and the children's voice.

Debatten om Biblioteksdatoriseringen : tendenser i Biblioteksbladet, Bis och DIK-forum 1970-1999

The purpose of this thesis was to trace and discuss tendencies in the debate of the computerization of the libraries, in Swedish library press during the period of 1970-1999. The set-out was the issue of how the library journals, as representatives and mouthpieces of a by tradition humanistic profession, coped with a revolutionary innovation related to a field (data technology) which they hadn't any knowledge or even interest in. The examination included three Swedish library journals: Biblioteksbladet with connection to Sweden?s most established library organization (SAB); Bis which is founded upon a socialistic base and; DIK-forum rooted in the union. The analysis of the debate was partly based on three different sets of values related to data and systems development.

Outsourcing av urval och inköp : En studie av hur bibliotekariens kompetens och yrkesroll påverkas av Bibliotekstjänsts profiltjänster

Traditionally, the majority of Swedish public libraries have carried out most of their acquisitions through Bibliotekstjänst's binding booklets. In recent years, however, many libraries have complemented the binding booklets and other services from Bibliotekstjänst by other ways of acquiring books, such as Internet bookshops, while other libraries have stopped using the binding booklets altogether. There are various reasons for this development, such as Information Technology making it possible for librarians to compare prizes and services from different retailers. Another important reason is the need for public libraries to meet new needs from their patrons, while remaining on a restrained budget, which often causes a need for reorganization of staff and resources.As a way of meeting the new needs for libraries, Bibliotekstjänst has created Profile Services (profiltjänster), a service in which a library outsources its acquisitions to Bibliotekstjänst. The staff of the library, in dialogue with Bibliotekstjänst, design a profile for the acquisitions for the library in question, in order to determinate which types and genres of literature the library and its patrons are requesting.

Informationspark? Informationsstrukturerna hos bioteknikföretagen på Ideon

This thesis deals with information provision to the knowledge intense biotechnology businesses of Ideon Science Park in Lund, Sweden. Previous research concerning the information needs of Science Park companies has been conducted from the information provider s perspective. Instead, we apply a user perspective to find out what information needs these companies have, and how they prefer to acquire information. Central terms are: information, -needs, -acquisition, -consciousness, -strategy, small and medium sized enterprises, scientists and engineers, information (resources) management, networks, tacit knowledge, knowledge transfer and innovative milieux. The companies need scientific and business information; the latter is easily obtained within Ideon.

The Nature and Role of Experiment in Science Education

Experimentets art och roll i naturvetenskaplig undervisning är ett fundamentalt och omfattande ämne. I föreliggande litteraturstudie görs ett försök att sätta in frågan i ett historiskt, pedagogiskt och vetenskapligt sammanhang. Innan experimentets roll diskuteras, ställs dock frågan vad naturvetenskap är, varför och hur det skall undervisas, och vad som kännetecknar praktiskt arbete och experimentell verksamhet i skolan. Med denna bakgrund refereras några forskares och lärares erfarenheter och åsikter. Det visar sig, föga överraskande, att formerna för och avsikterna med experiment i undervisningen är skiftande.

Omvärldsbevakning på bibliotek

The purpose of this article is to investigate how and from which sources librarians collect information on their profession with respect to factors that are important for their work. In order to achieve this goal, a questionnaire-based survey will be conducted at three medium-sized central-public-libraries in southern Sweden. Using this survey, I wish to answer the following four questions: To what extent do librarians acquaint themselves with changes and developments within regional and cultural policy arenas important to their work? To what extent do librarians acquaint themselves with information using conferences and library debates that are focussed on changes and developments relevant to their work? Do librarians consider that they have enough time within the limits of their work hours to follow developments within the librarian profession, for example with respect to developments within information technology, and how would they appraise the future demand for information technology-based services at the library? From which source(s) do librarians collect information relevant to their work? The theoretical basis of this paper can be compared to a radar as it scans subjects-of-interest to the organization in the field of business intelligence. This investigation uses a quantitative method, with data collected via a survey consisting of 13 questions.

Att skilja på sak och person - Hur ökad personifiering i media kan leda till bättre politisk kunskap hos mottagarna

Mass media is becoming more and more personalized and despite common ideas it could actually be a good thing. Instead of affecting the actual content of news coverage it might only have an effect on the way in which news are presented. Famous politicians more regularly become symbols and synonyms for their parties or for the government and are being used to create interest in the beginning of articles.Those are the results from a content analysis of the newspaper coverage of the Swedish parliamentary election in 1976 and 2006 in which the scientist categorized each article in one of four ideal types, counted quotes and analyzed whether personal names were interchangeable with party names without affecting the content. All three methods showing that it is the presentation, not the content, which has been personalized.At the same time, psychology-science tells us about the human brains associative learning processes, where memorizing becomes far more efficient when the information can be connected to an already known person. Increased personalization of news might therefore increase the political knowledge of the receivers..

Syftet med denna systematiska litteraturstudie var att undersöka studenters och sjuksköterskors inställning till informationsteknologi, samt studenters erfarenhet av IT och möjlighet att utnyttja IT i klinisk utbildning. Använda databaser var Medline, Science Direct, och Google Scholar. Följande sökord användes: nursing, student, documentation, attitudes to computers, computerized, och medical record. Femton artiklar ingick, varav nio hade kvantitativ ansats och sex kvalitativ ansats. Resultatet visade att yngre studenter inte hade lika högt förtroende för teknologi som äldre studenter.

Homosexualitet i tre klassifikationssystem under tre decennier: Ett queerteoretiskt perspektiv på SAB, UDK och DDC.

The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.

TECHNOLOGY MEETS THE EYE : Utveckling av system för att jämföra eye tracking data med visuellt stimuli

The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..

Förväntningar på Framtida Mobila Tjänster

Today?s society is very focused around technology and something that is very popular is the usage of mobile devices such as Smartphones or Tablet computers. One of the reasons why these devices are so popular, is because of the large amounts of services or ?apps? that they can provide for the user. They can do a lot of things that makes everyday living easier for the users.The focus of this study is to find out what kinds of mobile services the users of these devices are expecting and/or wishes to see in the future and what is required to be able to develop and use these services in a good way.We started of the study by searching for earlier studies on the same or similar subjects.
