Bokkapitel (refereegranskat)abstract
- The chapter presents an analysis of individual development as an integrated process, in which mental, biological, and behavioral aspects of individual functioning and social, economic, and physical factors in the environment are involved. It is suggested that an individual's way of thinking, feeling, acting, and reacting at any stage of the life process is the result of an integrated transformation process which takes place on the basis of biologically based potentialities and restrictions. The measurement implications of this view are discussed with reference to a person approach in research on developmental processes.

- The design of an efficient process flow-sheet requires accurate extraction data for experimental set-up used. Often this data is provided as equilibrium data. Due to the small hold-up volume compared to the flow rate in centrifugal contactors the time for extraction is often too short to reach equilibrium D-ratios. In this work single stage kinetics experiments have been carried out to investigate the D-ratio dependence of the flow rate and to compare this with equilibrium batch experiments for a SANEX system based on CyMe4-BTBP. The first centrifuge experiment was run with spiked solutions while in the second a genuine actinide/lanthanide fraction from a TODGA process was used. Three different flow rates were tested with each set-up. the results show that even with low flow rates, only around 9% of the equilibrium D-ratio (Am) was reached for the extraction in the spiked test and around 16% in the hot test (the difference is due to the size of the centrifuges). In the hot test the lanthanide scrubbing was inefficient whereas in the stripping both the actinides and the lanthanides showed good results. Based on these results improvements of the suggested flow-sheet is discussed.

Tidskriftsartikel (refereegranskat)abstract
- District heating in Sweden has undergone changes in recent decades. Parallel with transition towards sustainability,a considerable ownership restructuring has occurred, due to liberalization of energy markets.The aim of this paper is to describe and analyze trends of mergers and acquisitions in the Swedish districtheating market. A systematic review of ownership in 290 municipalities has been performed throughannual reports, press releases, websites, municipal minutes, newspaper articles and personal contacts.The paper shows a transformation from municipal to diverse ownership, decreased municipal ownershipand increased internationalization. The window of opportunity provided by liberalization was usedespecially by the “big three” (E.ON, Fortum and Vattenfall) in order to strengthen market position early inthe wave of acquisitions. The time period 1996–2005 was especially hectic, showing strategies of cherrypicking hot spots for acquisitions, with the “big three” being responsible for a large proportion of these.The period after 2006 showed trends of companies selling several district heating businesses at once,through large-scale disinvestment. The paper shows a transformation of the district heating regime, firstas a reaction to changes on the electricity market and later in its own right, raising concerns regardingthe weak position of customers.

Ägarförändringar på den svenska fjärrvärmemarknaden : en översikt över förvärv och avyttringar 1990-2014
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna studie behandlar ägarförändringar på den svenska fjärrvärmemarknaden. Avregleringen av den svenska elmarknaden, och tillika kommersialiseringen av fjärrvärmemarknaden (denna period av omregleringar kallas sammantaget i rapporten för liberaliseringar) medförde en rad försäljningar av kommunala energibolag men även förvärv och avyttringar av energirörelser i privat regi. Tidigare har ingen fullständig genomgång gjorts över hur liberaliseringen påverkade fjärrvärmemarknaden och denna rapport ämnar bidra till den kunskapen.Syftet med rapporten är att beskriva och analysera hur ägandeförhållanden på den svenska fjärrvärmemarknaden förändrats sedan 1990. Frågeställningarna är följande: Vilka år har fjärrvärmerörelserna sålts? Hur har ägarformerna och ägarförhållandena för svenska fjärrvärmerörelser förändrats till en följd av liberaliseringen? Vilka politiska majoriteter har styrt i kommunerna vid försäljningen? Vilka mönster kring ägarförändringar går att urskönja?Studien har genomförts genom en systematisk genomgång av de 290 svenska kommunerna och sammanställning har då gjorts för vilka energibolag som bedriver fjärrvärmeverksamhet idag, hur ägandet ser ut, när eventuella ägarförändringar ägt rum samt vilka politiska majoriteter som rått vid försäljningen. Materialet har inhämtats via kommuners hemsidor, energibolags hemsidor och årsredovisningar, genom sökningar i mediedatabasen Retriever samt via kontakter med kommuner och energibolag. Insamlingen avslutades 31 maj 2014 och ägarförändringar därefter är således inte med i rapporten.Resultatet från studien visar att det kommunala ägandet fortsatt dominerar men att det var en stor mängd kommunala fjärrvärmerörelser som avyttrats, totalt 83 stycken. Särskilt många avyttringar gjordes perioden från 1995 och framåt och efter 2005 har enbart åtta kommunala bolag avyttrats. De politiska majoriteterna vid avyttringarna visar på att den politiska färgen varierat, då det i 45 kommuner var rött styre vid tidpunkten för försäljning, i 26 kommuner var det blått och i 12 blocköverskridande styre. Tidigare studier har visat att ideologi inte varit viktigaste skäl till försäljning utan snarare ofta ansträngd kommunal ekonomi.Sammanställningen visar även att det kommunala ägandet fortsatt dominerar, då det i 148 kommuner (52 % av de 283 kommuner som har fjärrvärme) är helägda kommunala bolag som bedriver fjärrvärmeverksamhet, i ytterligare 20 är det bolag som samägs av kommuner och i 58 kommuner (20 %) är det helägt privata. I ytterligare 29 kommuner är bolaget delägt kommunalt, tillsammans med antingen privata eller statliga ägare. Största ägaren är numera tyskägda privata bolaget E.ON som bedriver fjärrvärmeverksamhet i 22 kommuner, som antingen ensam ägare eller delägare.Det utländska ägandet har ökat det senaste åren men det svenska dominerar fortsatt, genom ägande i 201 kommuner. I 27 kommuner är det norskt ägande, i 20 helägt tyskt, i 19 delat svenskt och utländskt och i 16 kommuner är ägaren utländsk (ej inkluderat Tyskland och Norge).De senaste åren har visat på fortsatt rörlighet på marknaden, särskilt genom kommunala återköp av fjärrvärmerörelser. Detta har skett i 21 kommuner, antingen genom återköp av tidigare privatiserat bolag eller att bolag som de etablerat bolaget tillsammans med köpts ut.De tre stora ägarna, E.ON, Fortum och Vattenfall, har de senaste åren gjort strategiska storskaliga avyttringar av mindre fjärrvärmerörelser, varav flertalet av avyttringarna gjordes på ett bräde till ett och samma bolag. Det var på detta sätt som Solør, Neova och Värmevärden snabbt etablerade sig som ägare i många kommuner, men med begränsade sammanlagda värmeleveranser.

Tidskriftsartikel (refereegranskat)abstract
- It is seldom that it is only the patient who is affected when someone is admitted to compulsory psychiatric inpatient care, the next of kin is usually also impacted. The aim was to describe the lived experiences of being a next of kin to a woman in need of compulsory psychiatric inpatient care. Ten next of kin were interviewed and the material was analyzed with a Reflective Lifeworld Research approach. The results show loneliness and feelings that their existence has collapsed. An emotional duality is described in the realization that the care is needed but they are devastated that the woman is there. A trust exists, but it changes when the next of kin are no longer a part of the care process.

Applications and Extensions of Reference Attributed Grammars
- 2003
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Programming languages are the main tools used to describe models of the real world and algorithms which manipulate these models. Over time much effort has been devoted to the task of making programming languages more high-level by enhancing their expressiveness, bringing it closer to the way the programmer thinks and reasons. The development of object-oriented programming languages is one important step in this direction. Object-oriented languages include several abstraction mechanisms to support real world modelling. The resulting models represent a balanced view of data and computation aspects. Declarative programming is another important principle, offering features to build general libraries of functions. The model of programming is here clean and simple: the programmer specifies a result as a function of others, thereby concentrating on what relationsships there are between values rather than on the order of computations. This thesis deals with techniques for making specifications of computations on abstract syntax trees more high-level. Such computations are performed in different language-based tools e.g., compilers, smart syntax-sensitive editors, software metric tools, etc. Our basis is Reference Attributed Grammars (RAGs), which combines object-oriented features with declarative programming to specify computations on abstract syntax trees. RAGs have proven useful e.g., for performing static-semantic analysis of object-oriented languages. A RAG is an extension of traditional or classical attribute grammars (AGs) which is a formalism in which the static semantics of a programming language can be specified using a declarative approach. Traditional AGs are often considered clumsy and difficult to use for some aspects of compiler related tasks, for example name- and type-analysis of languages with complex scope rules. By allowing references between distant nodes in the AST the RAG formalism facilitates these tasks. The object-oriented view of the grammar used in RAGs is a conceptual extension of AGs which make it possible to apply all the object-oriented advantages. In the thesis we deal with extensions of RAGs and how they can be combined to facilitate tasks further for the attribute grammar author. We also explore applications of the combined extensions. Furthermore, we discuss evaluation techniques for extended AG formalisms. Some extensions are formal, e.g., allowing cyclic dependencies between attribute instances while others can be characterized as conceptual. Conceptual extensions include the object-oriented modelling of the grammar and modularization concepts. Even in extended AG formalisms some specifications can be complicated to express while their equivalent imperative style implementations are almost trivial. Another objective of this thesis is therefore to show how the declarative approach used in attribute grammars can be combined with imperative techniques in a tool using aspect-oriented modularization and where modules can be implemented in either imperative or declarative style. The thesis consist of an introduction and three papers. The first paper deals with the application of RAGs to a new problem area; program visualization. The second paper describes a practical system for RAGs, based on aspect-oriented programming and the combination of imperative and declarative programming. The third paper describes a formal extension of RAGs supporting circular dependencies (CRAGs). The extended formalism opens up new application areas which is also discussed in the paper. The techniques have all been implemented and tested in practice. Our tool JastAdd incorporates the extended AG formalisms. Its modularization concept also allows imperative style modules to be freely combined with AG modules. An automatic evaluator construction capability that can handle the extended formalisms has also been developed.
