The struggle for the subjects: Reactions on the Swedish High School reform Gy 2007
Arbetet är en källstudie över inlägg publicerade på skolverkets hemsida. Studien undersöker reaktioner gentemot förändringar i det samhällsvetenskapliga programmet gällande ämnena religionskunskap, filosofi och psykologi. Skolverkets förslag att slå samman filosofi med psykologi kritiserades utifrån administrativa problem. Ämnena ansågs dessutom vara alltför olikartade för att slås ihop med hänsyn till deras vetenskapliga metoder, innehåll och historik. Resultatet är i linje med Lindes begrepp ämnesprofessionell kod och Hargreaves begrepp påtvingad kollegialitet.
Odlingsstrategier på organogena jordar : en studie om beslutsfattande bland KRAV-anslutna lantbrukare
This study examines how farmers certified by KRAV face proposed regulations on organic soils put forward by KRAV economic association among others, and how they are affected economically. These soils are, from an environmental perspective, interesting as a target for production regulations as they cause greenhouse gas emissions through decomposition of organic material when cultivated. The regulations advocate that organic soils should be grown with pasture where soil cultivation is only allowed every fith year which implies that possible adjustments of cultivation have to be made in order to fulfill the regualtions. Collection of data have been made through a questionnaire sent out to 574 farmers certified by KRAV. The answers have been analysed using a decision making model and statistical findings suggest that proportion of organic soils, type of production, economic conditions and farmers? goals and values have an influence on whether the regulations and potential cultivation adjustments have been considered or not.
Är det möjligt att förutsäga utfall av cochleaimplantation hos barn med auditiv neuropati spektrumstörning? ? En litteraturstudie
Auditory Neuropathy Spectrum Disorder (ANSD) is a collective term for a specific form of hearing loss within a heterogeneous population of patients with mutual audiological test-profile. Cochlear implantation in children with ANSD has been found to result in good outcomes. Previous research, however, has shown the existence of a subgroup of children with ANSD who do not benefit from cochlear implantation but instead are in need of alternative methods of communication. The aim of this literature review was to examine the possibilities to predict outcomes of cochlear implantation in children with ANSD by pre-, intra- or postoperative examinations/measurements and thereby evaluate in which cases cochlear implantation is an appropriate intervention within this group of patients. The material consisted of 10 scientific papers published between 2007-2014.
Detektering av sprickor i vägytor med hjälp av Datorseende
This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.
Letar Svenska kyrkan på rätt ställe? : - en kritisk diskursanalys av Svenska kyrkans reklamkampanjer
AbstractAim: The aim of this essay has been to study how the Swedish church has created the image of their religious activity through media. This has been by studying the three commercial campaigns launched by the Swedish church during the years 2000, 2001 and 2003. Questions asked are: How has the Swedish church chosen to profile it self? Which discourses can be recognized in the campaigns? Which messages has been communicated through the campaigns? How has these discourses created the image of the Swedish church?Method: The methodological framework is critical discourse analysis inspired by Norman Faircloughs? three-dimensional model. Thirteen images all part of the campaigns are analysed using a semiotic method.
Sammanställning av möjligheter att konvertera ICD till AIS för bedömning av risken för medicinsk invaliditet : En systematisk litteraturstudie
The aim of this study is to create an increased understanding of shared leadership and how it takes shape in the relationship between first-line managers in human service organizations. Shared leadership is seen as a complement to the traditional one-man leadership and briefly means that two managers share the role that usually is held by a single leader. The study has a qualitative approach based on semi-structured interviews with managers in human service organizations. The interviews mention the mangers thoughts and experiences about shared leadership and gain approval in the hermeneutic science field. The study is analyzed based on symbolic interactionism where perspectives from the theoreticians Mead and Goffman are used.
Skydd mot yterosion i slänter av finmorän
Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.
Att utkräva ansvar - en analys av Vattenfalls verksamhet i Tyskland
With the expansion onto the international market almost a decade ago, Swedish energy corporation Vattenfall began it's breaking and burning of coal on German soil. Criticism aimed at Vattenfall peaked in the mid 2000s with the revelation of large quantities of carbon dioxide emissions and the re-location of villages and graveyards in German states Brandenburg and Saxony. The purpose of this thesis is to show where the responsibility for these activities lie. By analyzing the history of, and the political debate surrounding, Vattenfall, I will show that the prevailing policies of right- as well as left-wing parties in the 20th century were all, regarding this matter, market oriented. I will also show that these market promoting policies made possible a situation where the transparancy of, and state control over, Vattenfall were close to eliminated.
Varför och hur integreras medier med svenskämnet? : En kvalitativ studie av tre pedagogers uppfattning om inkluderande arbetssätt
This essay is about why and how the media is integrated with Swedish as a subject. The purpose of the study is to investigate if the teachers who use different media when teaching Swedish consider that this pedagogy develops the students? learning. I also aim to find out if there are any differences and/or similarities between the teachers.To fulfil the purpose I have done a qualitative study with three teachers who work at a school. I have focused on following issues: How, when, where and why do the teachers use media when teaching Swedish?The investigation shows that media is popular today and it is becoming more so all the time.
Agroprotein som fodermedel till slaktkyckling
Destillers dried grains with soluble (DDGS) is a by-product when producing ethanol. DDGS from wheat has a high crude protein content and a good amino acid profile, which makes it an interesting feed ingredient for poultry. The disadvantage of feeding DDGS from wheat to poultry is that it also contains a high fiber content that chickens don?t have the ability to break down. Lantmännen Agroetanol has developed a new protein feedstuff from DDGS by extracting wheat protein from DDGS, the product name is Agroprotein SD.
Möjligheter att förutsäga kvävegödslingsbehov i höstvete med Yara N-tester
The Yara N-Tester is a handheld chlorophyll meter which can be used in several different
crops as an aid to determine if there is a need of complementary fertilization with nitrogen
(N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha.
The possibility to assess the need of N depends on the strong relation that exists between
chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series
?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was
carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters
ability to estimate the need of N in winter wheat, will be presented for the years
2008-2011.
Kvickrotsstudier: 1. Kvickrotens reaktion på myllningsdjup, kvävemängd och kväveplacering i konkurrens med gröda. 2. Reducerad glyfosatanvändning på trädad åkermark :
1. Reaction on burial depth and nitrogen availability and placement in competition with a crop
In this trial it was investigated how couch grass (Elymus repens) changes its ability to compete in stands of wheat and barley with different burial depth and different amounts and placement of nitrogen. More knowledge in this area can be valuable in the attempt to decrease the use of herbicides and still keep the weeds under control.
The trial was carried out in the summer of 2004 as an outdoor pot experiment. The pots contained 15 litres of soil with a surface of 0,06 m2.
Städer och planetära gränser : En utvärdering av Stockholms ochNorra Djurgårdsstadens påverkan påde planetära processerna
The concept of planetary boundaries was introduced in the year 2009 by a group ofresearchers led by Johan Rockström and Will Steffen. The group presented a draft of thelimits of the planet regarding nine Earth System processes concerning climate change, oceanacidification, stratospheric ozone depletion, atmospheric aerosol loading, interference with Pand N cycles, global freshwater use, land-system change, rate of biodiversity loss andchemical pollution. The starting point for the study presented in this report was that asustainable development only can be achieved if humankind stays within the boundaries. It istherefore, based on the ongoing urbanization, relevant to evaluate how cities affect the EarthSystem processes. The aim of the study was to investigate if Stockholm Royal Seaport (NorraDjurgårdsstaden), a district in the northeast of Stockholm with a clear environmental profile,affects the Earth System processes less than Stockholm in general does.
Investeringar i privat och kommunal verksamhet : En studie om faktorer som påverkar investeringar
The decisions for investment are forward-looking and the base of a long-term strategy. The research within investment have focused on diverse formulas which are used in financial assessment, which also should be complemented with qualitative evaluation. Consequently, the focus should not only be on the execution of the formulas. Less time have been spent on research concerning what actually initiates the investment proposals and affects the decision-making. This will be highlighted in this essay.
Visualisering av informationskvalitet : Utformning av kvalitetsindikatorer för Lantmäteriets Fastighetsregister
Fastighetsregistret (The Cadastre) is a large and important information sourcesupplied by Lantmäteriet (the Swedish mapping, cadastral and land registrationauthority). Fastighetsregistret provides geographical information about the 3.2 millionestates in use in Sweden. Fastighetsregistret has a large number of users who trustthat the provided data is reliable, but experience shows that the data can have varyingquality. As a user it is not always possible to access more detailed information inorder to assess to what extent the data in Fastighetsregistret is reliable.The purpose of this master's thesis is to investigate the possibilities of a system with agraphical user interface that present, classify and visualize the quality of the data inFastighetsregistret. The defined user group for this suggestion is internal users atLantmäteriet who have a good understanding of Fastighetsregistret.
