Denna uppsats behandlar förekomsten av rumslig autokorrelation i residualer till paneldatamodeller med tvåvägsfel. Tre modelltyper undersöks: den linjära paneldatamodellen, en dynamisk paneldatamodell och en spatial paneldatamodell. Ett känt resultat för den linjära modellen, att minsta kvadrat-skattaren tillämpad på oberoende observationer resulterar i en rumslig korrelation i residualserien varsThis thesis examines the spatial autocorrelation in residuals of two-way error panel data models. Three types of models are examined: the standard linear panel data model, the dynamic panel data model, and the spatial lag panel data model. A known theoretical result for the linear model, that the within estimator applied to independent observations results in a spatial correlation in the residuals

Rising costs of healthcare in most OECD-countries have contributed to a quest for research into the field of healthcare costs and efficiency, something that has not been free of controversies. As a result of that, healthcare financers as well as providers have become more inclined to measure performance and compare themselves to others with the same responsibilities. In Sweden, the Association of

We report on the application of simultaneous single-shot imaging of CH and OH radicals using planar laser-induced fluorescence (PLIF) to investigate partially permixed turbulent jet flames. Various flames have been stabilized on a coaxial jet flame burner consisting of an outer and an inner tube of diameter 22 and 2.2 mm, respectively. From the outer tube a rich methane/air mixture was supplied at

A lyotropic nonionic lamellar system composed of pentaethyleneglycol mono n-dodecyl ether and D(2)O was studied using natural abundance (13)C NMR under magic-angle spinning. Applying a two-dimensional recoupling method proposed by Dvinskikh (R-PDLF), (1)H-(13)C dipolar couplings were estimated over a range of temperatures (300-335 K), thus enabling analysis of structural changes in the liquid crys

Context. The Bulge is the least understood major stellar population of the Milky Way. Most of what we know about the formation and evolution of the Bulge comes from bright giant stars. The underlying assumption that giants represent all the stars, and accurately trace the chemical evolution of a stellar population, is under debate. In particular, recent observations of a few microlensed dwarf star

We have studied the effect of a grain boundary in front of a short edge crack on its propagation under cyclic loading conditions in bcc iron. The used model is a combination of a discrete dislocation formulation and a boundary element approach where the boundary is described by dislocation dipole elements, while the local plasticity is modeled by discrete dislocations. The grain boundary is consid

Both globally and from an individual perspective, water is the most important resource we have on earth. Knowledge of groundwater and groundwater recharge is important from many perspectives, such as environmental, socio-economic and structural engineering. The thesis is written at Lund University in Environmental sciences and aims to highlight groundwater recharge to the crystalline bedrock and g

This paper analyzes the interactions between Kazakhstan stock market index and maroeconomic variables. The vector autoregressive model (VAR) is employed; Granger causality, impulse responses and variance decomposition tests are implemented. The results show weak interactions among tested variables and the market. The only variable that could be used as explanatory power for price movements in stoc

University teachers funded to engage in educational development projects have been found to become increasingly engaged in the scholarship of teaching and learning. However, research also points to obstacles such as departmental culture, lack of support from management, and unhelpful administrative processes. In this study, I interview university teachers and their heads of departments in an educa

Rural Germany is massively dependent on fossil fuel driven cars. But in many villages, socio-technical innovations have emerged to tackle this dependency. Electric carsharing, often organised in grassroots-settings, is one of them. For such innovations to spread and grow, different projects from across the country need intermediariesto connect them in networks, or share ideas, and experiences. Thi

This paper contains some new results on the hadronic light-by-light contribution (HLbL) to the muon g − 2. The first part argues that we can expect large effects from disconnected diagrams in present and future calculations by lattice QCD of HLbL. The argument is based on the dominance of pseudo-scalar meson exchange. In the second part, we revisit the pion loop HLbL contribution to the muon anoma

The article is a result of field studies on the transformations of multicultural heritage in the east-central European cities of Cracow, Wrocław, Lviv and Chernivtsi. In all these cities, a majority of the pre-war populations (and in Wrocław, practically all pre-war residents) disappeared as a result of WWII. After decades of silence imposed by the ruling communist elites, collective memories of t

Environmental management in the City Tunnel Project was a three-year, sociology of law research project (1999-2003) on how the new Environmental Code was applied to one of the largest infrastructural projects in Sweden: the City Tunnel in Malmö. The aim of this article is, after some years, to reflect on and re-examine what happened during the two extended consultations processes to try to find an

Background: Drug therapy in primary care is a challenge for general practitioners (GPs) and the prescribing decision is influenced by several factors. GPs obtain drug information in different ways, from evidence-based sources, their own or others? experiences, or interactions with opinion makers, patients or colleagues. The need for objective drug information sources instead of drug industry-provi

Popular Abstract in Swedish Målsättningen med föreliggande studie är att belysa det komplexa och varierade bruket av skogliga utmarker under järnålder, medeltid och tidig modern tid. Fysiska lämningar från landskapet Värmland i västra Sverige undersöks, med särskilt fokus på lokalsamhällena Dalby och Gunnarskog.

Material evidence from the landscape of Värmland, in Western Sweden, will be examined, focusing on the local societies of Dalby and Gunnarskog. Evidence for the reconstruction of outland activities comes from a range of sites, including pit
