Syftet med avhandlingen är att beskriva och analysera hur Försäkringskassans organisationskultur har förändrats. Mer specifikt är syftet att fånga förändringarna i Försäkringskassans organisationskultur genom att studera tjänstemännens relationer, reaktioner och handlingsstrategier över tid. De centrala frågeställningarna är följande: ”Hur har försäkringskassans organisationskultur förändrats?”, ”In 2005, The Swedish Social Insurance Agency (Försäkringskassan), was reformed from being local county authorities to a nationalized and integrated organization. The aim of this thesis is to describe how Försäkringskassan’s organizational culture has changed. The key questions are: ”How has Försäkringskassan’s culture changed?”, ”How are the organizational culture perceived and handled by the empl

This thesis deals with various aspects of growth, convergence and technological change, all analysed from an empirical perspective. A common theme throughout the six chapters is the analysis of economic historical questions of productivity growth with the use of quantitative statistical techniques. An introductory chapter is followed by two chapters on the Western European regional growth and conv

This study investigates the sensitivity of wastewater treatment plant (WWTP) model performance to the selection of one-dimensional secondary settling tanks (1-D SST) models with first-order and second-order mathematical structures. We performed a global sensitivity analysis (GSA) on the benchmark simulation model No. 2 with the input uncertainty associated to the biokinetic parameters in the activ

Male-female differences may significantly impact stroke prevention and treatment in men and women, however underlying mechanisms for sexual dimorphism in stroke are not understood. We previously found in males that cerebral ischemia upregulates contractile receptors in cerebral arteries, which is associated with lower blood flow. The present study investigates if cerebral arteries from men and wom

III-V semiconductors have attractive transport properties suitable for low-power, high-speed complementary metal oxide-semiconductor (CMOS) implementation, but major challenges related to cointegration of III-V n- and p-type metal-oxide-semiconductor field-effect transistors (MOSFETs) on low-cost Si substrates have so far hindered their use for large scale logic circuits. By using a novel approach

Precision hard turning is an emerging innovated machining technology for machining hardened workpiece (60 similar to 62 HRC) with characteristic of better flexibility, high production rate, and cost saving. However, one of problem in this process is that it is difficult to remove the thermal distortion of the workpiece induced by the heat generated during the process, especially in the case of pre

Rheumatoid arthritis (RA) is a systemic disease not only restricted to the joints, but can also be associated with the development of extra-articular manifestations. Extra-articular RA (ExRA) is of clinical importance because of the associated morbidity and increased risk of premature mortality compared with RA patients in general. The aims of this work were to identify patients with ExRA in early

Aims. We seek to provide 2MASS and OGLE identifications and coordinates for all stars in the finding chart published by Arp (1965, ApJ, 141, 43). This chart covers the low extinction area around NGC 6522, also known as Baade's window, at coordinates (l, b) = (1.02, -3.92). Methods. A cross correlation, using numerical techniques, was performed between a scan of the original finding chart from Arp

The article examines leader ship as an aspect of everyday work inter actions. Drawing on the findings of an ethnographically inspired study of superior-subordinate relations in a bank, it argues that leader ship can be understood as embedded in everyday work-activities, rather than seen as distinct from these. Relying on the framework of discursive psychology, a micro-level analysis of an informal

We present a theory for a mesoscopic turnstile that produces spatially separated streams of electrons and holes along edge states in the quantum Hall regime. For a broad range of frequencies in the nonadiabatic regime the turnstile operation is found to be ideal, producing one electron and one hole per cycle. The accuracy of the turnstile operation is characterized by the fluctuations of the trans

While each new generation of processors gets larger caches and more compute power, external memory bandwidth capabilities increase at a much lower pace. Additionally, processors are equipped with wide vector units that require low instruction level divergence to be efficiently utilized. In order to exploit these trends in ray tracing, we present an alternative to traditional depth-first ray traver

This paper presents a novel control architecture for hybrid stiff and compliant control for minimally invasive surgery which satisfies the constraints of zero lateral velocity at the entry point for serial manipulators. For minimally invasive surgery it is required that there is no sideways motion at the point where the robots enter the abdomen. This is necessary to avoid any damage to the patient

Soft tissue sarcomas (STS) are challenging as they represent a morphologically and genetically heterogeneous groups of tumors. A multitude of genetic changes, often in the form of fusion genes, were recognized during the 1980's and now constitute a diagnostic lexicon in several STS subtypes, whereas many of the more common subtypes are genetically complex without distinct alterations. Refined STS

Popular Abstract in English A central requirement in the design of bridge, or any structure, is that they are safe and do not fail unexpectedly. To ensure that such occurrences are acceptably rare involves predicting the various ways in which the bridge can fail and ensuring that provisions are made to prevent or control these potential failure. In other words, the risks associated with failure shEngineering design, in concise terms, is what engineers do using what they know. It is the underlying decision making activity that determines what is to be built and how it should be built. An ever present requirement in engineering design is that the structure should be safe. While historical approaches to safety in design relied on experience and engineering judgment, modern approaches have rat

Network formation of graphene oxide (GO) nanoplatelets was held accountable for the modification of the rheological properties of nanocomposites based on poly(3-hydroxybutyrate) (PHB). The nanocomposites were prepared by a casting procedure from the green solvent γ-butyrolactone. The nature of the GO network and percolation limits were analyzed by making use of the molar mass reduction of PHB that

Anomaly detection is becoming a powerful and necessary component as wireless networks gain popularity. In this paper, we evaluate the efficacy of PCA based anomaly detection for wireless mesh networks. PCA was originally developed for wired networks. Our experiments show that it is possible to detect different types of anomalies in an interference prone wireless environment. However, the sensitivi
