"De är ett väldigt nyfiket släkte, barnbibliotekarierna". En kvalitativ undersökning av hur 1990-talets samhällsförändringar påverkat barnbibliotekariernas arbetsuppgifter, kvalifikations- och fortbildningsbehov
The purpose of this master thesis is to investigate what the work situation of children's librarians looks like in the year 2000, after the changes in society which took place since the 1980's. Did the tasks of children's librarians change during the nineties, and if so, in what way and why have they changed? Which new knowledge needs emerged for children's librarians during the nineties, and what was the cause of these new needs? Finally I want to know which needs for professional development arose, and how these needs are fulfilled. The thesis is based on qualitative interviews with children's librarians, library managers, library consultants, one representative of the Swedish school of Library and Information Studies and one member of SAB's children and youth committee. The study reveals that the identity of children's librarianship is strongly associated with the stimulation of language and reading.

Alkoholintag efter träning och dess inverkan på muskeluppbyggnad och återhämtning hos vuxna män - En systematisk litteraturöversikt
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Alcohol consumption after training and its effects on muscle gain and recovery adult menAuthor: Frida Carlstedt, Puck JanssonSupervisor: Frode SlindeExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 09, 2014Background: Today, the Swedish population exceeds the recommendations for alcohol intake while advised to move at least thirty minutes a day. It is well established what happens if you drink alcohol before a workout or if you workout the day after an alcohol intake, but it is less well established how muscle gain and recovery are affected by an intake of alcohol in the phase of recovery.Objective: The objective of this review is to investigate if there is a relation between alcohol intake after a workout and effected recovery and muscle gain. This was performed by measuring the outcomes cortisol, testosterone, creatine kinase as well as different measures of muscle strength. The issue was ?Does an intake of alcohol after training affect recovery and muscle gain??Search strategy: A systematic review in the databases PubMed and Scopus with the MeSH-terms: exercise, muscles, recovery of function, training, athletic performance, performance, sport, alcohol drinking, alcohols, alcohol and ethanol.Selection criteria: Criteria for articles to be included in this review were that they would be RCT- and human studies in healthy subjects as well as containing an ethanol intake after a physical activity that consisted of weight training in the form of resistance training or other forms of activity that promotes strength.Data collection and analysis: A systematic search for literature as mentioned above (search strategy) was performed as well as an analysis with the SBU quality review template for randomized studies, and a quality review for each measure of outcome according to Gothenburg University summarized evidence template for measures of outcome.4Main results: Many studies are authored by the same group of researchers and/or are of a lower quality.
Design of a Direct-conversion Radio Receiver Front-end in CMOS Technology
In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.
Wickrpedia : Integrering av sociala tjänster
The web has evolved much through the years. From being a place where author and reader were clearly distinguished, it now invites everyone to take part in the development of both content and technology. Social services are central in what is called Web 2.0. Wikis, blogs and folksonomies are all examples of how the users and their communities are key to the development of services. Collaborative writing, tags and API:s are central.
"Kolla vad jag hittade!" Förskolebarns bilderbokssökning med samspel i fokus
The purpose of this study is to investigate how children search for and choose picture books while visiting the library together in a preschool group. How do children interact with each other and their teacher while searching for picture books? Which aspects of children's everyday lives are apparent in their choice of picture books? The theoretical frame of reference consists of Brenda Dervin's sense-making approach to information seeking and William Corsaro's sociological approach to studying children's routine activities within a peer culture. To capture children's interaction, we have observed a preschool group consisting of six 3- to 5-year olds and their teacher in a library setting during three visits. Our study shows that children's search for picture books is a social activity that involves various verbal and nonverbal strategies in order to include and exclude each other when they find a picture book that interests them.
Kan Hedvig lösa De mystiska tecknen? : en studie av två biblioteksdataprogram för barn
This thesis examines which function the information technology may have in thechildren's library, with the example from two library computer programmes. One is anexpert system, Hedvig, which will help children to choose and to find books, and theother is a computer game, The mysterious signs, that will teach children library user education.The main question is: What conceptions do the project-leaders, the children'slibrarians and the children have concerning the function of these two programmes in thechildren's library?The study is based upon qualitative interviews with two projects-leaders, fourlibrarians, three computer programmers and twenty-eight children.The theoretical material consists of examples on other library computer programmesfor children developed in Denmark and USA, some American studies in children'sabilities to use computerized information retrieval systems, and studies concerningchildren's relations to computers.The adult's conceptions of the computer programmes are divided into categories asfollows: Democracy, aspect of sex, complement, marketing, reading promotion,development of competence, information technology development, pedagogics, adulteducational activities, compensation and armusement, pedagogics, usefulness,effectiveness and information. These categories shall be seen as the conclusions of the thesis..
Värdering av katastrofers miljökonsekvenser
When a disaster occurs the main focus is on the loss of human lives. Here the environmental effects have been in the centre of attention. This work has had two main purposes. The first one was to formulate attributes, variables that together present a complete picture of the consequences that an event has had on the environment. The other main purpose was to investigate how people value the impact that a disaster can have on the environment.
Nostalgiska Ljud
Det finns ljud som är på väg att försvinna i takt med teknologins utveckling. Dagens ungdomar har aldrig hört ljud från den äldre teknologin, som den äldre generationen har fått växa upp med såsom skrivmaskinen, modemet m.m. Dessa produkter gav ifrån sig ett speciellt ljud som numera inte hörs lika mycket idag. Men vad händer när tekniken utvecklas till den grad att ljud blir en säkerhetsfråga? Förutom teknikljud finns det ljud från förhistoriska och nyligen utdöda djur som forskare har lyckats återskapa genom studier av kvarlevornas anatomi.

Att se världen i svart och vitt : En kritisk granskning av SOS Barnbyars reklamkampanjer
The purpose of this thesis is to do a critical review of the aid organization SOS Children?s Villages text- and video campaigns, from a postcolonial perspective. Our purpose is divided into two questions: Are there colonial values in the advertising campaigns? Which language- and image strategies are used by SOS Children?s Villages to put across their messages? Our material consists of 10 selected video clips, and four printed ads that are made up of an image and a short text, which are part of a campaign named: Inte ett enda barn ska behöva vara ensamt (translation: Not a single child should have to be alone). We have chosen to use text- and image analysis as a method in our review of the material.
