We compare different procedures for combining fixed-order tree-level matrix element generators with parton showers. We use the case of W-production at the Tevatron and the LHC to compare different implementations of the so-called CKKW scheme and one based on the so-called MLM scheme using different matrix element generators and different parton cascades. We find that although similar results are o
Popular Abstract in Swedish Organisationskreativitet och psykologiskt v älbefinnande. I den föreliggande avhandling föreslås det att hur kreativitet och innovation uttrycks i organisationen är kontextberoende. Att kreativitet och innovation kan bidra till en ekonomisk tillväxt är allmänt känt.

Present day organizations in a globalized society are experiencing external challenges and changes more than ever before and in order to adapt and react to these changes creativity and innovation are seen as some of the most important means. The standpoint in this thesis is that all employees have creative potential, and how the creative pote
Platelet-derived growth factor-B (PDGFB) is necessary for normal cardiovascular development, but the relative importance of different cellular sources of PDGFB has not been established. Using Cre-lox techniques, we show here that genetic ablation of Pdgfb in endothelial cells leads to impaired recruitment of pericytes to blood vessels. The endothelium-restricted Pdgfb knockout mutants also develop
Popular Abstract in Swedish Denna avhandling analyserar frågor som berör tillfälliga jobb på den svenska arbetsmarknaden under perioden 1990-1999. Ett viktigt bidrag i avhandlingen är att den stora gruppen tillfälliga jobb delas upp i mindre undergrupper för att ta i beaktande den heterogenitet som finns mellan olika former av tillfälliga jobb. En röd tråd som löper genom hela avhandlingen är fokuThis thesis analyses different aspects of temporary jobs in the Swedish labour market during 1991-1999. Throughout the thesis we put special focus on differences between the genders, and differences between native-born and foreign-born workers. In chapter 1, An Introduction to Temporary Jobs in Sweden, we describe the evolution of different types of temporary jobs in Sweden during the 1990s, we re
International organisations (IOs) play increasingly important roles in world politics. As states face more complex challenges they have joined together in IOs to solve their common problems. Yet once an IO has been created it may take on a life of its own, and it becomes difficult for its state founders to control what it does. Permanent secretariats populated by experts are one of the most import
Under istider, när stora mängder havsvatten var bundet i inlandsisar, var den globala havsnivån lägre än idag och stora delar av kontinentalsockeln torrlagd. Den senaste istiden (cirka 115 000–12 000 år sedan) var inget undantag, då torrlagda områden utvecklades till ekologiskt rika kustområden som möjliggjorde människans spridning över världen. När inlandsisarna smältesteg havsnivån och dessa lanDuring times of lower global sea level, vast areas of the coastal shelf were exposed and converted into ecologically diverse coastal landscapes that wereattractive for human occupation. The landscapes were subsequently flooded during the deglaciation, but well-preserved remains of these landscapes andtheir inhabitants can today be found on the seafloor. In the southern Baltic Basin, where the comp
The following study explores the economical and political determinants influencing the Swedish parliamentary election outcomes, through the lens of statistical modeling. With analysis of election data from 1970-2022, we employed both multiple regression and ridge regression to explore the following key variables: immigration, taxation, unemployment, inflation, poll performance, incumbency, margina
Frågan om alkohol- och drogtester på arbetsplatser har blivit en alltmer framträdande och komplex fråga. Med en betydande ökning av sådana tester under de senaste åren har debatten om balansen mellan kontroll och personlig integritet intensifierats. Å ena sidan söker arbetsgivare att minimera risker associerade med alkohol- och droganvändning genom att skapa en säker och drogfri arbetsmiljö. Å andThe issue of alcohol and drug testing in the workplace has become an increasingly prominent and complex issue. With an increase in such tests in recent years, the debate about the balance between control and privacy has intensified. On the one hand, employers seek to minimize risks associated with alcohol and drug use by creating a safe and drug-free work environment. On the other hand, workers fa
Arbetet undersöker huruvida vägran att tillämpa det förväntade lagförslaget om anmälningsplikt, den så kallade anmälningslagen, dels kan motiveras utifrån civil olydnad, dels kan rättfärdigas. Anmälningslagen är fortfarande under utredningen men ett förslag förväntas presenteras hösten 2024. För-slaget har kritiserats av fackförbund, kommuner och intresseorganisationer, varav en del av kritikerna The paper aims to investigate whether the refusal to apply the proposed Re-porting Act might be justified. The Reporting Act is still under investiga-tion, but a proposal is expected to be presented in the fall of 2024. Unions, municipalities, and various organizations have criticized the Act, and a few of them have called on the people to break the law in advance. They claim that civil disobedien
This thesis explores the positioning of internal crisis communication in relation to external communication, specifically within the context of governmental crisis response. Guided by the case of the Lebanon crisis in 2024, this study investigates how crisis experts from a European Ministry of Foreign Affairs interpret internal communication across the three phases of crises, drawing on the Rhetor
Bakgrund: En lindrande åtgärd för patienter som drabbats av artros är höftprotesoperation. En höftprotesoperation är inte riskfri utan flera komplikationer kan uppstå för patienten och några av dessa är infektion och djup ventrombos (DVT). Förebyggande åtgärder mot infektioner efter höftprotesoperation är antibiotika vilket det finns klara direktiv för. I förebyggande mot DVT efter höftprotesoBackground: A hip replacement surgery is a major surgery with several complications that can occur to the patient such as infection and deep vein thrombosis (DVT). Preventive measures against infections after hip replacement surgery are antibiotics for which there are clear directives. In prevention against DVT after hip replacement surgery, thrombosis prophylaxis is given. Thrombosis prophyla

I denna studie användes en kritisk realistisk tematisk analys för att besvara studiens frågeställThe present study examined which factors patients with panic disorder with or without agoraphobia (PD/A) describe as helpful in Panic Control Treatment (PCT) and Panic-Focused Psychodynamic Psychotherapy (PFPP). RCT-studies have indicated that PCT and PFPP are effective treatments for PD/A. This study applied a critical realistic thematic analysis to answer the research question. The 32 participan
Popular Abstract in Swedish Små, trådlösa och portabla apparater utgör idag en stor del av vår uppkopplade värld. Under det senaste decenniet har dock flera teknologiska framsteg lett mot en utveckling där allt från maskiner till kläder kommunicerar med varandra. Detta brukar kallas för "sakernas internet" och uppskattas involvera 50 miljarder enheter år 2020. Genom att förse dessa enheter med småThe modern small devices of today require cheap low power radio frequency (RF) transceivers that can provide reliable connectivity at all times. In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. There are several architectures for implementing an ADC, but in the last decade, continuous-time Delta-Sigma mod
I svensk rätt finns det en huvudregel i 21 kap. 2 § rättegångsbalken om en skyldighet för en misstänkt i brottmål att närvara vid huvudförhandling i tingsrätt och hovrätt. En sådan skyldighet finns inte om målet kan avgöras utan att den misstänkte är närvarande och närvaron kan antas vara utan betydelse för utredningen. Är den misstänkte skyldig att infinna sig personligen, ska rätten förordna om In Swedish law there is a rule in Chapter 21. 2 § RB on the obligation of a suspect in criminal cases to be present at the main hearing in court. Such an obligation does not exist if the case can be settled without the accused being present, and presence can be assumed to be irrelevant to the investigation. When the suspect is required to appear in person, the court shall notify the accused in adv

Cholesterol is an essential membrane component enriched in plasma membranes, growth cones, and synapses. The brain normally synthesizes all cholesterol locally, but the contribution of individual cell types to brain cholesterol metabolism is unknown. To investigate whether cortical projection neurons in vivo essentially require cholesterol biosynthesis and which cell types support neurons, we have
Omfattningen av fukt- och mögelskador på uteluftsventilerade kalla vindar har ökatunder de senaste decennierna. Detta beror på ett flertal samverkande faktorer såsom ettvälisolerat vindsbjälklag samt byte från lokal värmekälla med varm skorstensstock tillandra uppvärmningsformer som inte bidrar till uppvärmningen av vindsutrymmet. En-ligt gängse rekommendationer ska kalla vindsutrymmen ventileras On a cold-ventilated attic, there is always an outer roof that must be tight against snow and meltwater, which means that there are also materials in the construction that make it more or less vapour tight. In traditional roofs, the waterproofing layer often consists of an asphalt-impregnated paperboard on a tonged and grooved board. As an alternative to the conventional solution, a less diffusion
