Näthat : I gråzonen mellan straffrättsligt ansvar och yttrandefriheten

The following thesis concerns the conceptualization of openness within the open access movement. Open accesscan be understood as a phenomenon or a movement that aims at changing the current system of scholarly communication.Consequentially, the movements goals arose in relation to the escalating serials crisis in scholarly communicationand the increasing power of commercial publishers. The purpose of the thesis is to study three centralopen access declarations with the aim of uncovering the different conceptualizations of openness found withinthese texts. Leaning on the theoretical position known as actor-network theory, the declarations role within a surroundingnetwork is explored by focusing on how openness as a concept has been produced and reproduced bycentral actors. Two overarching questions frames the study: How is openness conceptualized within the declarations?And how can openness, as a concept, be understood as an effect generated by a larger network?The first part of the study focuses on the first question.

Skadlig kod och sårbarheter i Windows : En studie i virusens historia och nutidens olika säkerhetsrisker

I dag kan man oftast läsa om olika säkerhetshot och risker en datoranvändare måste tänka på för att inte ge någon utomstående möjlighet att komma åt känslig och/eller privat information. Här talas det om nya virus och nya typer av trojaner som sprids som epidemier över Internet, och i bland handlar det om ett spionprogram som följer med en nedladdad fil. Det är svårt att hålla reda på alla typer av skadlig kod som nämns fast med ökad förståelse ökar också chanserna för att klara sig från smitta. Det har visat sig att utvecklingen av skadlig kod är lika stark som den inom kommersiella mjukvaror. Från persondatorns uppkomst i början av 80-talet och fram till i dag, har utveckling skett i alla områden av den skadliga kod det handlar om strategi, syfte och framförallt ren kodkomplexitet.Dagens ledande leverantör av operativsystem och webbläsare, Microsoft, lovar allt mer sofistikerade säkerhetslösningar varje gång en ny version av ett program släpps.

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.

Gr?n Gentrifiering p? Hisingen: En spatial och kvantitativ analys av gentrifieringsvariabler och parker 2015-2023

This study examines whether a spatial relationship exists between blue-green infrastructure and indicators of gentrification in Hisingen, Gothenburg, during the period 2015?2023. Using a GIS-based approach, sociodemographic changes across 83 demographic statistical areas (DeSO) were analysed in relation to six parks established or significantly developed during the study period. Changes in mean income, educational attainment, share of residents with foreign background, and mean age were combined into a gentrification index, which was then tested against distance to the nearest park through linear regression analysis.The results show that socioeconomic changes consistent with gentrification occurred across parts of Hisingen during the period, with the highest index values concentrated in the central and south-eastern parts of the district. However, these changes were geographically selective rather than district-wide.

Sjuksköterskans följsamhet till hygienriktlinjer i omvårdnaden av sjukhusvårdade patienter

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures.

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.
