Popular Abstract in Swedish Den svenska grundskolan har under de senaste åren genomgått och genomgår fortfarande en stark utveckling inom ramen för den allmänna decentraliseringen i samhället. Beslut och ansvar läggs allt längre ner i organisationen. De krav som ställdes på en skolledare tillbaka i tiden var i första hand att han skulle vara administratör och den som bevakade att skolans verk-samThe issues of the study are: How do the assistant principals face the work as school leaders? Which demands of competence do the new school leaders face? Which needs of competence development exist for new school leaders? In the school studied the organization of the management was changed from one principal and one director of studies to one principal and six assistant principals. All of these we

The interaction of a solid target with an ultra-high intensity laser pulse can result in the laser plasma acceleration of ions. The recent proposal of a new laser plasma ion acceleration scheme, named chirped standing wave acceleration, has created interest in a new class of ultra-thin solid target materials, either freestanding or as a part of novel compound targets. In this thesis, it is assesse

This thesis aims to explore the workflow related to designing an application specific instruction-set processor (ASIP). An ASIP is a processor similar to a hardware accelerator (HAC) in terms of performance and efficiency, but containing elements of general purpose processors (GPPs) when it comes to programmability and flexibility. The thesis centers around the design of an ASIP which will handle

Wireless adhoc networks transmit information from a source to a destination via multiple hops in order to save energy and, thus, increase the lifetime of battery-operated nodes. The energy savings can be especially significant in cooperative transmission schemes, where several nodes cooperate during one hop to forward the information to the next node along a route to the destination. Finding the b

Damping is present in all dynamic systems. In one way or another energy is being dissipated in the system. To capture this aspect of reality in a computational model is a difficult task. A common simplification is to assume that the damping is of a linear viscous nature. This assumption provides an equation of motion (linear dynamics) which is easy to handle mathematically. However, the simplicity of

Den svenska rätten känner inget kollektivt straffansvar. Något som kan ses som ett avsteg från denna princip är den del av medverkansläran som kallas medgärningsmannaskap och då framförallt den variant som brukar kallas utvidgat medgärningsmannaskap. Medgärningsmannaskapet innebär att två eller flera personer döms som gärningsmän för att ha begått ett brott, tillsammans och i samförstånd eller gemThis thesis concerns the procedural aspect of the legal construction of joint perpetratorship. Joint perpetratorship is a part of the legal doctrine of complicity and applies when two or more persons together commit a criminal offence. According to this legal construction they can both be charged and sentenced as perpetrators if they were in agreement about committing the offence. This thesis sets

I takt med en ökande befolkningsmängd och den pågående digitaliseringsprocessen, finns det ett behov av en effektiv planeringsprocess. I Sverige finns det både nationella och internationella mål som berör detta. Detaljplaner är ett viktigt verktyg för att reglera planeringsprocessen. Vid nybyggnationer och förtätningar av städer krävs det att analyser utförs för att säkerställa att krav på buller,In line with an increasing population and the ongoing digitization process, there is a need for an effective planning process. In Sweden, there are both national and international goals that concern this. Zoning plans are an important tool for regulating the planning process. In the case of new constructions and densification of cities, it is required that analyzes are carried out to ensure that r

Type 2 diabetes has become a leading health problem throughout the world. The escalating epidemic of type 2 diabetes is believed to result from a collision between inherent biological susceptibilities (genotypes) and a shift toward dietary habits and lifestyle that promote obesity over the past several decades; the transition from “traditional” to modern “obesogenic” lifestyles is characterized by

Introduction: Universal screening for preterm delivery by adding transvaginal ultrasound measurement of cervical length to routine second trimester ultrasound has been proposed. The aim is to estimate inter- and intraobserver agreement and reliability of second trimester transvaginal ultrasound measurements of cervical length performed by specially trained midwife sonographers. Material and method

This dissertation deals with design and characterization of functional structures for scattering of electromagnetic waves. An abundance of these structures can be found in nature, such as the structural coloration in the feathers of a peacock, the scales of butterflies and the shell of scarab beetles. Human design of structures providing specific interactions with electromagnetic waves have a long

The aim of this thesis was to characterize a personal denuder/filter sampler for isocyanate aerosol and to study the emission of airborne particles from the interaction between studded tires and pavements. Both types of aerosols are highly relevant for health studies in public and occupational environments. The adverse health effects of airborne isocyanate exposure are well known in the occupatio

Background: Vasovagal syncope (VVS) is a common yet challenging condition with limited effective treatments. Elastic compression stockings (ECS) have been proposed as a potential therapy, but their real-world effectiveness remains unclear. Objectives: This study sought to compare the effectiveness of lower extremity compression with thigh-high ECS vs sham stockings for the prevention of VVS recurr
