Det vi vet när vi glömt allt vi lärt oss : den politiska debatten om utbildning för nyanlända elever på 1970-talet och 2000-talet
The purpose of the present paper is to examine the political debate on the education of newly arrived immigrant pupils at secondary school age. The following issues are under scrutiny:What are the goals, expressed by politicians during the examined periods, for the education of newly arrived pupils?What ideas about education and what educational ideals can be observed in the political debate on the education of newly arrived pupils?Has there been any change, during the examined period, in the policy debate on the education of newly arrived pupils?The research material consists of reports and statements of the Education Committee, as well as a number of parliamentary protocols. Two five-year periods, 1971-1975 and 2006-2010, are studied and compared. All in all, the material consists of 23 documents issued during these periods.
Förekomst av penicillinkänslighet hos blododlingsisolat av Staphylococcus aureus
Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.
Det etiska ledarskapets roll i kampen mot korruption - En studie om antikorruptionsarbete i den svenska banksektorn
Despite Sweden's ranking as one of the least corrupt countries in the world, recent studies suggest that the prevalence of corruption in the private sector is growing, now approaching international levels. Over the past couple of years, Sweden has witnessed a growing number of scandals involving unethical behavior on the part of its corporate sector. Corruption has gained the attention of authorities, legislators and the public - putting the private sector under pressure to take action to prevent such corporate misconduct. As a result, companies increasingly prioritize strategies and policies aiming to prevent corruption. This study aims to contribute to the understanding of the role of leadership in such preventive work.
Enklare korglutning
This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.
Att investera i en karriär : Övergången mellan studier och arbete för studenter med utländsk bakgrund vid Växjö universitet
Numerous studies raise the topic of highly educated immigrants whose education and list of qualifications devalue in the context of the Swedish labour market. However, little is known of those with foreign background who enter into higher education in Sweden. Our study attempts to shed some light onto the value of higher education relative to that of a person?s ethnic background. The background material features nine in-depth interviews of foreign background academics, as well as data extracted from an extensive survey study previously carried out at Växjö University. Initially, the quantitative data showed that students with foreign background, including Swedish-born children of immigrants, had not managed to find qualified work upon completion of studies to the same extent as their Swedish background counterparts.
Genetiska studier på fågelinfluensa :
In the spring of 2006 we had our first outbreak of avian influenza of highly pathogenic H5N1 (HPAI) among wild birds in Sweden. This disease have impact on poultry industries world wide. Sporadically the virus infects other species than birds and we now know it can even cause fatal infection of humans. There are not yet any confirmed cases of transmission of the disease between humans though a suspected case in an Indonesian family is under investigation. If a mutation occurs that changes the pathogenicity and host affinity to humans we are at a risk of a new pandemia, perhaps like the Spanish flu in 1918-1920.
Den Svenska Självgodheten: Hur kan CSR och den sociala dimensionen i Sverige för detaljhandeln förstås, när detaljister gör anspråk på CSR samtidigt som personalvillkoren i branschen försämras
The concept of corporate social responsibility (CSR) has lately gained popularity throughout the globalized world. Swedish retail industry is no exception. Though increased levels of explicitly claimed responsibilities of companies, a number of other facts points out a development that contradicts this trend. Labour conditions and forms of employment is substantially retrograding, with an increased level of insecurity characterizing the Swedish retail labour market. At the same time, almost all Swedish retail companies explicitly state claims on social responsibility.

Autumn water sources for understory vegetation and fungi in a boreal forest : an evaluation using stable isotopes
Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest
components. During early autumn in boreal forests, temperature falls and large events of rain are frequent which may influence soil water availability. To better understand the autumn plant-soil-fungi water relationships in this ecosystem, I used stable isotopes techniques in this
study to examine the water sources for ericaceous shrubs and fungi in a Scots pine forest following a large, early autumn rain event. I hypothesize that ericaceous shrubs of two functional groups (evergreen vs.
Survey of Fusarium species on yellow onion (Allium cepa) on Öland
It has been observed by both onion producers and a plant protection advisor on Öland (an island off the east coast of Sweden) that basal rot is the largest contributory factor to reduced onion quality and yield. Basal rot is mainly caused by species of Fusarium fungi. The aim of this study was to: a) investigate which species of Fusarium that can be found in onion produced on Öland, b) describe the symptoms caused by the different Fusarium fungi found and c) explore, through interviews with the onion producers on Öland, the mechanisms that may be involved in the observed increase in basal rot.Onion bulbs (Allium cepa) were sampled on two occasions. In total 181 onions from 11 different fields were analysed. In addition, eight onion producers were interviewed.

Privata och offentliga riskreduceringsmekanismer och dess inverkan på beviljande av handelskrediter
Bakgrund och problem: Majoriteten av försäljningen mellan företag, samt mellan företag och offentlig sektor sker via handelskrediter. Detta leder till att företagen ofta blir utsatta för risker i form av sena och uteblivna betalningar. I sådana situationer finns det behov av riskreduceringsmekanismer som ska reducera och minimera dessa risker. Mekanismerna för reducering av risker har vi fördelat i två kategorier, privata och offentliga. Avsikten med uppsatsen är att undersöka vilka av dessa mekanismer som har störst inverkan på beviljandet av handelskrediter.
Kognitionsforskning i djurhållningen: grisars kognition och dess tillämpning vid slaktsvinshållning
Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made.
A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.
Kontraktsstyrning och kvalitetsindikatorers utformning vid kommunal upphandling : En flerfallsstudie
Management by contract is nowadays a common method within the public sector since the NPM overtook as paradigm with its mechanisms of control inspired by the private sector. The public agency is foremost a service provider where they interact with citizens in the service process. Swedish eldercare has significantly increased its expose to competition which means that eldercare can be executed not only by the municipalities own provider. Such an adaption increases the requirements to inspect quality and how the purchasers assure goal achievement by control. The outmost liability stays with the municipality to ensure that the service produces god care since their position as the service purchaser implies the responsibility to plan, precise and evaluate the required work that the executor has to accomplish.
Odour-mediated behaviour in codling moth, Cydia pomonella : do fermentation odours affect the attraction and oviposition behaviour in codling moth?
The codling moth, Cydia pomonella is a common pest in apple orchards and can be found worldwide. Feeding by codling moth larvae can cause a substantial decrease in apple yield. Control methods comprise for example the use of pesticides, viruses and pheromones. As a sustainable control method, pheromones have been successfully applied to disrupt moth mating behaviour. Other behaviours like foraging, search for mating sites or host finding could be potential targets for additional odour-mediated behavioural manipulation but need further investigations of the underlying odour stimuli and behavioural plasticity.
Many insects are attracted to the smell of fermenting fruit and associated microorganisms.
