Debatten om bibliotekarieutbildningen ? inför förändringarna av utbildningen år 1972 respektive år 1993 ? sådan den återspeglas i bibliotekstidskrifter

The purpose of this thesis is to examine the debate in library journals and in official reports on the subject of library education in Sweden. We focus on two periods: the period just before the year 1972 ? when the library education was transformed into being occupationally-oriented and the period just before the year 1993, when the library education was transformed into being ?academised?. This Master?s thesis shows that the debate and the arguments among initiated people in the library world have had some impact on how the library education was transformed later on.

Vad styr förekomsten av sälg och asp? : en studie av olika beståndstyper inom Hamra kronopark, Dalarna

Aspen (Populus tremula L.) and goat willow (Salix caprea L.) are two important tree species in the aspect of nature conservation. Due to the elimination of forest fires, a former negative attitude towards deciduous trees in forestry and a strong herbivore pressure, these tree species have been negatively affected during the last fifty years. The aim of this study was to investigate whether the occurrence of aspen and goat willow could be related to either human impact or to site properties, such as ground moisture and vegetation type. A side study included an inventory of a number of cyanobacterial tree lichens on aspen and goat willow in order to try to relate the occurrence of these lichens species to stand history and stand properties. The study was performed in Hamra State Forest in northern Dalarna. Nature reserves were compared with stands in managed areas.

Kärnkraft : Ett arbete för drifttekniker?

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

Fördelning av frambensskador på ytliga böjsenan hos galopphästar :

Superficial digital flexor tendon injuries are common causes of premature retirement or pre-longed convalescence periods for race horses. The curve gradient at Täby Galopp race track is very small and most races as well as high speed training are done on the left rein. It is believed that the horses left foreleg is under considerably more strain then the right foreleg when being ridden on the left rein during gallop at high speed. During gallop on the left rein the horse puts its entire weight on the left foreleg when regaining ground contact. The purpose of this study has been to find out, through analyzing the statistics concerning the horses that visited the ATG clinic at Täby during a period between January 2003 and September 2006, whether there is a higher frequency of superficial digital flexor tendon injuries on the left leg rather than the right and if so, can this support the theory that the design of the race track in combination with continuous left rein races can be a contributing cause of these injuries. The result of the study shows that 57% of the tendon injuries occurred on the left front leg and 38% on the right front leg. The difference is not large enough to support the above theory of the underlying cause of these injuries..

Energikartläggning och driftoptimering genom behovsstyrning i befintlig fastighet

Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.

Vem skapar nyheterna? : En kvantitativ studie av nyheters ursprung och prioritering i svenska riksmedier

Syftet med undersökningen är att analysera varifrån nyheterna har sitt ursprung och hur återanvändandet av nyheter ser ut i fyra av de största riksmedierna under en arbetsvecka.De fyra medier som ingår i undersökningen är Svenska Dagbladet, Dagens Nyheter, Sveriges Televisions Rapport och Sveriges Radios Ekot. I undersökningen ingår 356 analysenheter och det är en kvantitativ undersökning. För att förstå och analysera resultatet har teorierna gatekeeping, mediernas kommersialisering och nyhetsvärdering använts.Undersökningens resultat visade bland annat att 27 procent av analysenheterna består av köpt eller kopierat material från nyhetsbyråer eller material som är omskrivet från andra medier. Undersökningen visar också att det är stora skillnader mellan olika medietyper. Den största andelen material från nyhetsbyråer kom från tidningarna Dagens Nyheter och Svenska Dagbladet (såväl procentuellt som i absoluta tal).

Utveckling och formgivning av en framtida radio

Arbetet syftar till att genom en litteraturstudie samt ett antal kortare intervjuer som skickas ut via e-post göra en grundläggande undersökning av CFRP (Carbon fibre reinforced polymers) därtill hur användningen av förstärkningsmetoderna ser ut idag. Rapporten skall ta upp hur projektörer bör arbeta när de träffar på produkter som är nya på marknaden.Att förstärka betongkonstruktioner med kolfiberförstärkning har blivit allt mer vanligt under de senaste åren. Även stålband eller stålbalkar används för att förstärka bjälklag och liknande konstruktionselement. Anledningen till att en byggnad eller annan typ av konstruktion måste förstärkas kan bero på ett flertal olika saker, bland annat om byggnadens användningsområde ändras.Kolfiberförstärkning är i jämförelse med stål mycket starkt i förhållande till sin vikt. Tunna förstärkningar gör stor skillnad.

Det brinner i förortens ungdomsroman : bilden av unga män med utländsk härkomst i 2009 års samhällsrealistiska ungdomsroman.

The aim of this paper is to examine how young men of foreign background are pictured in the realistic adolescence novels of 2009. In my process of work I have used a classical schedule for literature analysis from which I have worked out a few questions to use on my texts. The questions are related to the main characters and some of the most important minor characters ? all are young men with foreign background ? and focuses on aspects of for example where they live, who their friends are and what they think about and dream of.To put these pictures into a wider perspective I compare my results with the well known stereotype picturing of men with foreign background in media. I then discuss how or if this affects the young men?s picture of themselves and the majority society?s picture of them.

Syftet har varit att med hjälp av en diskursanalytisk ansats studera nationella mediediskurser som berör de som benämns ?gömda flyktingbarn?. Detta för att se hur de framställs och vilka möjliga konsekvenser det får för det sociala arbetet.

Två dagar senare ... En uppsats om helgens guldkant

About a year ago, Göteborgs-Posten, one of Sweden's largest daily newspapers, decided it was unprofitable to continue producing their feature-style weekend magazine, Två Dagar. Standing at a crossroads,not wanting to stop producing the weekend magazine altogether, they decided to outsource. Spoon Publishing AB, a content agency with strong ties to Göteborg, were assigned with taking over the production.Going forward, Spoon has taken over a majority of the responsibility for the conceptual work and actual production, all with the main purpose of reducing cost and increasing efficiency.Normally Spoon does content marketing for a wide range of customers in an equally wide spectra of channels, from print to radio, television and web.The main purpose of this essay has been to investigate and establish whether the journalistic integrity and quality has in fact been maintained despite the weekend magazine being outsourced. We have analyzed selected editions of the magazine, first and foremost inarticles under the vignette fashion, using a qualitative method for content analysis, scrutinizing everything from the denotation of single words to the big picture. This specific vignette contains the most frequent contributions by in-house, or at least reappearing, journalists.Perusing the material in Två Dagar, we have come to the conclusion that the magazine has indeed retained its level of quality and still reflects the same core values as before being outsourced..

Barn med 22q11.2 deletionssyndromet ? hur hör de?

The 22q11.2 deletion syndrome is a common genetic disorder that affects for example the heart, palate, immune system and hearing and therefore affects a child?s development. The purpose of this study was to investigate the proportion of children (0-18 years) with 22q11.2 deletion syndrome who have a hearing loss. A retrospective study of 103 children diagnosed with 22q11.2 deletion syndrome was conducted by medical records. Of the 103 children, 51 were boys and 52 were girls.

Vilken reklamkanal av annonsering, direktreklam, tv- och radioreklam skapar störst uppmärksamhet och intresse hos singelhushållen i en medelstor stad, där avsändaren är en livsmedelshandlare?

Bakgrunden till följande rapport var att vi ville undersöka vad singelhushåll i en medelstor stad anser om reklam, samt vilken reklamkanal av radio, tv, direktreklam och annonser som skapar störst intresse och uppmärksamhet hos dem som målgrupp. För att kunna undersöka målgruppen singelhushåll utformades följande frågeställning: ?Vilken reklamkanal av annonsering, direktreklam, tv- och radioreklam skapar störst uppmärksamhet och intresse hos singelhushållen i en medelstor stad, där avsändaren är en livsmedelshandlare?? Undersökningen var för oss relevant eftersom det tidigare inte utförts någon undersökning av denna målgrupp och för att singelhushållen idag växer i antal. Teorierna som användes i denna rapport handlade om hur företag med hjälp av marknadskommunikation kan nå ut till sina konsumenter. Det står om vad reklam är och i vilka kanaler den kan förmedlas.

Hållbarhetsredovisning i svenska företag: - utveckling, trender och drivkrafter

This study aims to investigate development and reasons behind sustainability reporting in large Swedish companies. By examining 15 companies? environmental and sustainability reports between the years 2000 and 2008, data was collected on matters such as frequency, scope and design. Identified trends were to a large extent in line with previous studies on international development; sustainability reporting is growing in several aspects. The authors have found one major reason for this development to be increasing requirements and expectations from stakeholders and a need for companies to legitimize their actions.

Skyddande isolering i samband med stamcellstransplantation : Patienters upplevelser av den skyddande isoleringen samt uppfattningar om sjuksköterskans roll under vårdtiden

When going through a stem cell transplantation a patient is forced to undergo protective isolation to inhibit risk of opportunistic infections related to the low leucocyte count as a result of aggressive pre-transplant chemotherapy treatment. Protective isolation has shown to have an impact on patient experiences during treatment and the aim of this study is to elucidate experiences of protective isolation of patients undergoing hematopoietic stem cell transplantation and to deduce patient perceptions of the role of nurses in protective isolation care. The presented study was performed as a mixed qualitative and quantitative survey at a hematopoietic ward in Sweden. Results were analyzed by Mayring (2000) and by descriptive frequency charts and show that patients in protective isolation experience alienation, necessity, safety and anxiety with regards to their protective situation. Considering the role of nurses patients perceive their role to be attendant, informant and acting as an executioner of medical implementations.

Högfrekventa tryckvariationer under de senaste århundradena

Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.
