Att återberätta glädje : En studie av struktur och språk i fem pojkars personligt återgivande texter
The aim of this study is to investigate how five boys in grade 3 of compulsory school structure and use language when they write narrative texts retelling and assessing personally experienced events. This is studied by interpreting how the boys use genre steps that are typical of the structure of personal narrative texts and by detecting and naming different linguistic features in the texts. The material in the study consists of five boys?personal reports and the method, which is based on the theories of genre pedagogy (see Johansson & Sandell Ring 2012:28ff, 223f), comes from systemic functional linguistics. A central finding of the study is that the boys structure their texts in varying combinations of genre steps which commonly occur in texts of a narrative kind.
Rektorn och skolbiblioteket : uppfattningar om skolbiblioteket
The purpose of this thesis is to describe how principals apprehend the school library. In order to respond to this I formulated three questions: How was the improvement of the school libraries carried out in one municipality? Is the school library experienced as a part of the schools organization? How is the use of the school´s library experienced? To be able to answer these questions, for the purpose of this thesis, I have studied relevant literature on school libraries, the school organization and literature on qualitative methods. I have made six qualitative interviews. The objects of the interviews were three librarians and three principals.
Reformation i förändring? : Bilden av reformationen i svenska kyrkohistoriska verk
ABSTRACTIn this study I have analyzed, throughout a gender perspective, two textbooks Den levandelitteraturen and Upplev litteraturen which are purposed to be used as teaching materials inSwedish schools in the subject of Swedish when teaching the history of literature. The intentof this study was to provide a gender analysis of two textbooks and the focus was on thepresentations of female and male writers, because they have not been studied earlier. In thisstudy, a qualitative text analytic method was used to achieve the best results as possible.Theories used in this study were Yvonne Hirdman?s and Raewyn Connell?s theories. Hirdmanclaims that there are differences between men and women at different levels in the societywhile Connell believes that this is a myth because, according to her, men and women arepsychologically alike.
Evaluation of the retinal ON- and OFF-responses in the dog ERG
The aim of the study was to examine the retinal ON- and OFF-pathways of the canine electroretinogram (ERG). The ON- and OFF-pathways are used to distinguish objects from
their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background.
This study shows that the dog ERG has both ON- and OFF-responses and that these responses can be separated by prolonging the flash duration over 50 ms. The dog OFF-response waveform was more similar to the cat OFF-response than the human OFF-response
(Frishman, 2006; Zrenner and Gouras, 1979).
In this study six female three-year-old Beagle dogs were included. Both background and flash stimuli were provided by LEDs (light emitting diodes) with a wavelength of 470 nm, a wavelength that is absorbed almost as effectively by the canine M/L-cones as by the S-cones.
These stimuli gave ERGs with both ON- and OFF-responses.
Komfortsanalys med hänsyn till vibrationer orsakade av människoaktiviteter. : Ett modernt dimensioneringsproblem för huskonstruktörer
Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.
"Information-as-thing": Förhållandet mellan biblioteks- & informationsvetenskapen och materialbibliografin
The relation between LIS and physical bibliography is examined primarily through an analysis of such LIS literature as applies physical bibliography in research or otherwise discusses its relevance to information studies. Quite a number of scholars are stressing the usefulness of this bibliographical tradition, even though its position in LIS agenda as a whole seems to be less established. These scholars suggest that physical bibliography presents interesting conceptual and theoretical implications for many of the central objects of study in LIS, for example, knowledge organization, information retrieval, and information seeking. It is also suggested that physical bibliography could help deepen our knowledge and understanding of the digital media ecology. Physical bibliography is foremost seen as a method for the analysis of documents, a method in which not least its terminological apparatus may be a significant tool.
Detaljhänsyn efter slutavverkning : kvantitet och inverkan på framtida produktion hos SCA i Västerbotten
According to FSC (Forest Stewardship Council) shall at least a mean of 10 trees per hectare including riparian zones and other areas with high biological values be left in final felling. In addition large clear areas should not be created and all retained trees with high environmental value shall be spared. To leave trees in final felling means a lower cutting volume and hence a lower income from the cutting, but it also means that the production in the next generation becomes less because of competition. The aim of this study was to evaluate the effect retained trees have on the production in the new generation of forest, and to investigate if there is any way to lower this effect. The environmental care has also been estimated by the amount left in final felling.
Rissepareringens effekter på viltets nyttjandegrad av GROT
Successful forest regeneration is a prerequisite for sustainable forest management. Therefore, it is important to prevent browsing damage on the commercially important tree species Scots pine. In this study I have tested a new alternative way to increase the available amount of forage and increase the use of these resources by especially moose. The method is based on a slash treatment at harvest, where the accessibility of slash as forage is increased during final felling or commercial thinning by gathering the slash and putting the Scots pine slash on top of the slash piles. This study has compared the availability of forage, the amount of browsed biomass and the number of fecal pellet groups between conventional and slash treated stands after final felling and commercial thinning in southern Sweden.
Nollföljdsmodellering av transformator-Beräkningar av följdproblem vid ökad kablifiering på mellanspänningsnivå
Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.
Den gotländska Stridsyxekulturen : migration, interaktion eller regionalitet?
This one-year master's thesis investigates the late part of the Middle Neolithic on the island of Gotland. This thesis has been written without the influence of a singular theoretical pespective, and has therefore seen input from the processual, and postprocessual theories. By using several perspectives, an attempt is made to view the material remains used in the most objective manner possible. The specific aim of this thesis is to investigate whether the Mid-Neolithic inhabitants of Gotland were a part of the Corded Ware culture (or as it is called in Sweden, the Battleaxe culture or the Boataxe culture). Most recent literature has concluded that Gotland was never a part of the Battlexe culture, though this thesis has discovered many parallels with the mainland culture, including the production of similar objects and ritual practices.
Ger man sig in i leken, får man leken tåla- eller? : En kvalitativ intervjustudie med poliser om våld och hot i arbetslivet
Våld i arbetslivet har de senaste tio-femton åren uppmärksammats inom den kriminologiska forskningen. Tidigare sågs ämnesområdet som tämligen ointressant ur forskningssynpunkt, främst eftersom våld i arbetslivet skiljer sig från det traditionella ?gatuvåldet?. I tidigare studier har man intervjuat vårdpersonal och restaurangpersonal där resultaten tyder på att personalen blir utsatt för våld, men att våldet ses som en del av arbetet.Denna studie består av kvalitativa intervjuer med fem poliser om deras upplevelser av våld och hot i arbetslivet. Studiens syfte är att undersöka vad poliserna själva upplever som våld och hot samt om de anser att de måste tåla en viss typ av våld eller hot i tjänsten.
Generationsskräpsamling med explicit kontroll av hårdvarucache
This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..
E-learning ? en utbildningsmetod och dess nytta
Companies that invest in e-learning have different expectations regarding the outcome of the investment. According to literature and articles it is common that companies see reduction of costs as the primary benefit with e-learning. Therefore we ask ourselves the question if companies have attained the expected benefit of the investment in e-learning and to what extent cost reduction have been a determining factor in the investments? The purpose of the thesis is to examine if companies that invest in e-learning have attained the expected benefits. We also want to examine what the reason for investing in e-learning is and if cost reduction is the primary reason for investing.
Östersjöledningen : En studie i åsikter och människors trygghetsupplevelse belyst av media
The Nord Stream natural gas pipeline has been a controversial project. The debate was primarily escalated by Poland's strong negative reaction to the project in the spring of 2006 over safety and security and then alternated back and forth in Europe until the approval by the nations most concerned in the Baltic region during the autumn of 2009.In the case study an approach is used that primarily maps out the media image of the various viewpoints that deal with the pipeline and how these viewpoints position themselves, primarily through political and environmental dimensions. Simultaneously there?s an attempt to map out the spatial spread of the media image views as to the proximity and distance to the pipeline in Sweden, Poland and Germany. A key question is whether distance or proximity to a large facility can affect people's attitudes.A parallel focus of the study is to explore the role of the Nord Stream natural gas pipeline in the cross-border hinterland region of Szczecin-?winouj?cie.
Media och dess inverkan : exponering av idealiserade könsroller och dess inverkan på unga människor
The purpose of this study is to examine the impact that idealised body images found in media have on the body-image and wellbeing of young men and women. The study was carried out using questionnaires based on the BAQ and HAD scales to examine the participants' views of themselves as well as symptoms of anxiety and depression. Time spent by the participants using different kinds of media, as well as their degree of social support, was used with the purpose of examining relations and differences in body-image between men and women. The questionnaire contained advertising images to examine whether short time exposure had any impact on the participants. In order to determine this, one half of the questionnaires contained idealised body-images, whilst the other half contained images without human objects.
