När pojkar betraktas som män : en kvantitativ och kvalitativ studie om åldersgräns för tonårspojkar på Sveriges kvinnojourer
This paper aimed to investigate to what extent there is an age cut-off for teenage boys in the women?s shelters of Sweden and how a possible cut-off is described and maintained. This occurrence has not been investigated earlier to a large extent, which emphasizes the importance of this paper. A mixed strategy was used to cover both the frequency as well as the explanations to the age cut-off. The quantitative survey was sent to all women?s shelters in Sweden and the result showed that 56 % of the shelters had an age cut-off for teenage boys from 12 years of age and above.
Modelering av Wideband : Code Division Multiple Access
Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.
Electronic Journals, Just in Case, Just in Time, Just for You ? användning av elektroniska tidskrifter vid Chalmers tekniska högskola
This user study was carried out at the library at Chalmers University of Technology in Gothenburg in the spring of 1999. Chalmers wanted to investigate how much their employees use electronic journals. To facilitate decision-making and be cost effective, the library needed to know about their customers' opinions. The main purpose was to investigate the usage of electronic journals, how the library's choice of these journals affects the frequency of use and what the attitudes towards them are. A questionnaire was sent out to 2 400 employees; 477 replies were received.
Vox pop, enkät och fem funderar. : En kvantitativ innehållsanalys av enkäter i tre svenska dagstidningar åren 1997 och 2007.
The purpose of this BA-thesis was to study how three daily Swedish newspapers use a specific type of exemplars, which are recognized by a number of attributes. A photograph of the person that is interviewed always illustrates this type of exemplars and at least two persons are asked the same question. The three newspapers that have been compared in this study each represent one of the major types of Swedish newspapers: morning press, tabloids and local press. By using a quantitative content analysis, one month was examined in all three newspapers in the year of 1997 and 2007. Two of the theories that have been central in the thesis are Colin Sparks model of tabloidization, which demonstrates the process of tabloidization and McQuail?s description of commercialization.
Hjärtinfarkt borde vara så självklart : Sjuksköterskors upplevelser av att vårda äldre kvinnor med hjärtinfarkt
BackgroundWhen women have breast pain this usually is not associated with myocardial infarction, which results in that they get less attention and wrong treatment. The nurse has an important role in informing and educating patients and families during hospitalization, which is usually short. Continuous training, written information and repetition for patient and family throughout the hospital stay are of considerable importance to clarify that the patient understands and to reduce the anxiety of being discharged.AimThe aim is to describe nurses' experiences of caring for older women with myocardial infarction.MethodsA qualitative method was used. The collection of data was done by six interviews with nurses in geriatric care and elderly care. Dataset has been processed based on a content analysis and divided into subcategories and main categories using meaningful units.ResultsNot having knowledge of older women with myocardial infarction was expressed as frustrating and nurses described how they were afraid to ask their colleagues.
Hydroakustisk kommunikation med bandspridningsteknik
This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.
Elevers användning av digital film i gymnasieskolans matematikundervisning : Vinster och möjligheter
Vi har idag god tillgång till tekniska hjälpmedel för att förmedla kunskap, Statistiska Centralbyråns [SCB] undersökningar från Sverige visar att nästan alla i åldrarna 16-24 år har tillgång till en dator i hemmet. För många av våra barn och ungdomar är det vardag att kunna hantera en dator. Detta skapar goda förutsättningar för ett fortsatt användandet av film i matematikundervisningen. Forskning visar att användandet av mediepedagogik är gynnsamt för språkutvecklingen och ett välutvecklat matematiskt språk är en av förutsättningarna för att kunna utveckla den matematiska förståelsen.Studien behandlar matematiska filmer av den art man finner på internet. Syftet är att studera hur gymnasielever använder sig av dem, vilka parametrar som fångar elevernas förståelse och intresse samt att få svar på vilka vinster och möjligheter mediet kan ge enligt eleverna.
Intensiv Stamningsterapis effekt på stamningsbeteenden, förståelighet och attityd till kommunikation hos fem barn
The purpose of this study was to investigate the effects ofparticipation in an integrated intensive stuttering program (IST) on stutteringbehavior, intelligibility and communication attitude, at individual and grouplevels. Five children aged eight to twelve years participated in the study.Stuttering behavior and intelligibility were judged by two independentstudents in speech and language pathology based on a total of eight videorecordings, before, during and after therapy. Communication attitude wasmeasured by the Swedish version of the self-report questionnaireCommunication Attitude Test (CAT-S). At an individual level, the initialstuttering profile and the changes shown during and after the IST varied. Ata group level, a significant decrease in stuttering frequency and asignificantly higher level of intelligibility were found, after as compared tobefore therapy.

Dramapedagogik utifrån fyra perspektiv : En hermeneutisk litteraturstudie med utgångspunkt i frågorna vad, varför och hur?
I denna studie fördjupar jag mig i ämnesområdet dramapedagogik. Med utgångspunkt i fyra dramapedagogiska perspektiv försöker jag beskriva och förklara dramapedagogik samt skapa förståelse för och inspirera till arbete med detta. För att uppnå detta har jag genom en hermeneutisk litteraturstudie utgått från de didaktiska frågorna vad, varför och hur. Dramapedagogik är ett ämnesområde vilket kan delas in i fyra pedagogiska perspektiv. Med agering som grundstomme fokuserar varje perspektiv på olika sidor av personlighets-, förståelse- och kunskapsutveckling.
Reagera och agera: Styrka och snabbhet i den manuella responsen för emotionella stimuli
In this study I investigated whether the strength in the manual response for emotional and neutral stimulus search arrays can explain some of the difference in reaction times (RT:s) for emotional stimuli, or not. Earlier, perceptual, cognitive and attentional processes has mostly been used to explain the variance in RT:s. Thirtythree individuals were asked to, as fast as possible, detect a target picture among distractor pictures in 3 rows x 4 columns arranged search arrays. The pictures were categorized in fear relevant animals (snake, spider) and neutral animals (cat). The results showed, more correct responses for cat target.

Arrangering : Arrangera rocklåtar för blåsinstrument och kompgrupp
Denna text beskriver hur jag under höstterminen 2013 jobbat med att arrangera rocklåtar för blåsinstrument och kompgrupp. Den beskriver mitt arbete inför ett uppförande av mina arrangemang och beskriver min process och tillvägagångssätten för att uppnå mina mål.Mina arrangemang spelades upp på en privat fest på Berns salonger den 9 november i Stockholm. Då tiden var knapp och endast en kort repetition med alla medverkande musiker var inbokad inför konserten så handlade stor del av mitt arbete att försöka jobba så effektivt som möjligt. Detta för att spara tid, samt för att de medverkande musikerna skulle få sina noter i god tid. För mig har det varit en lärorik period.
Hur har införandet av automatiska mjölkningssystem påverkat juverhälsan hos mjölkkor och vilka riskfaktorer finns?
Today, there are more than 12 000-14 000 farms worldwide using an automatic milking system (AMS). Studies have shown that transition to AMS affects the udder health of cows adversely, recognized primarily as elevated somatic cell counts. There are several reasons for this, for example the greater variation in milking frequency seen in AMS. On one hand, short milking intervals may lead to bad teat condition of the cows due to the stress the milking procedure exposes the teats to. Too long milking intervals, on the other hand, seem to predispose for milk leakage, which is, in turn, a risk factor for the development of mastitis.
