This thesis focuses on four different aspects of history teachers’ comprehensiveunderstanding of the school subject history. More specifically, the aim is tostudy the comprehension of the subject as perceived by individual historyteachers. Special emphasis is placed on identifying the concepts of the field ofhistory that are central to the teachers’ understanding of the school subject history.The first aspect studied is the teachers’ biographical changes. In a life historyperspective it seems as if the teachers’ subject conception changes from anunproblematic and tentative approach to a more complex and confident understandingof the subject. The second aspect treated is the rationale behind theirgrasp of the purpose and content of the subject. Three major positions areidentified, namely educational (bildung) orientation, critical orientation, andidentity orientation.The third aspect studied is the teachers’ interpretation of a curriculumnew to them. The teachers placed the curriculum in the field of tension betweenan education policy position, emphasizing more precise knowledge, onthe one hand, and a history science position, emphasizing concepts of historicalconsciousness. The fourth aspect studied is five different conceptual tools displayedin the teachers’ remarks on having completed the teaching of a newcourse. These are termed ‘history as narrative’, ‘history as time-space’, ‘historyas explanation’, ‘history as perspective taking’, and ‘history as skills’At the general level the study shows not only that subject conception is ofimportance to the teachers’ understanding of their obligation as teachers of historybut also how it is formed and constantly transformed by many differentfactors. In this process it is clear that the concepts used by the teachers, althoughvariously defined, can be seen as specific to the school subject historyand essential to the construction of history as a school subject.

The overall purpose of this study is to gain knowledge about dialogues in the setting of the preschool. The more in-depth purpose is to highlight what happens in dialogues between a teacher and a child when more children join the situation of interaction in which the dialogue is taking place. A further purpose is to attempt to understand what it is that influences change in the dialogue and what significance the actions of the teacher can have for this change. The study is based on several questions that concern interaction in preschools, who it is that initiates an increase in the number of participants in those situations that involve dialogue, and what happens with the dialogue when more children join and what causes the change in the dialogue. The study is based on video observations from a preschool; approximately 10 teachers and 50 children between the ages of one and six took part in the study. The situations that were observed and documented in video format were everyday activities (both indoor and outdoor) that were led at a nominal level by teachers. In total, 40 films were recorded. Film length was between one and 60 minutes. In 32 of the films, there was interaction between a teacher and several children, and 18 of these included dialogues between a teacher and several children. Dialogue is here given a specific significance and refers to the interaction that can be described in terms of presence, listening, reciprocity, and extending. This definition of dialogue derives from a combination of Martin Buber’s philosophy of dialogue and aspects of interaction that earlier research found to be significant for children’s learning. In two of the 18 films that showed dialogue, no other children became part of the situation of interaction; the remaining 16 films were transcribed; and both verbal and non-verbal events were made apparent in the transcriptions. Analyses of the recorded material and of the transcriptions were conducted using analytical terms borrowed from conversation analysis as well as the central term for this study dialogue.  The results demonstrate a complex practice and also demonstrate that dialogues in the sense given in this study take place between children and teachers. Situations of interaction also occur where dialogues take place in which a number of children join. It can be the child joining the situation of interaction who takes the initiative to an increased number of participants; however, it can also be the teacher or the child in the dialogue. The initial address can take place during a moment of transition in the interaction or at the same time as another participant is talking. The dialogue often changes when more children join the situation where the dialogue is taking place. The dialogue can end completely or be interrupted and resume. The results further demonstrate that the dialogue can continue without seemingly being affected by the fact that more children join. This happens when the child joining and the teacher in the dialogue interact in a non-verbal manner at the same time as the teacher is talking with the child in the dialogue. The dialogue can also be continued with more participants. Who takes the initiative, how the initial address occurs, and which content is given focus by the different participants are all factors that seem to affect what happens to the dialogue. How the teacher acts when more children join also appears to be significant in terms of what happens with the dialogue when more children join. In those situations where the teacher begins talking with a number of children about different subjects, the interaction ceases to be dialogic. When the teacher asks the joining child to wait, the dialogue is both interrupted and resumed, and on those occasions when the dialogue continues with more participants, the teacher listens to the joining child and the participants take turns speaking.

Toughness for a soft society? On medialisation, racialisation and the politics of spin in Sweden In recent years, issues concerning the future of “multicultural Sweden” have become a salient feature in Swedish politics. One important actor in recent years’ debates about the problems confronting “multicultural Sweden” is the Swedish Liberal Party. Since the general election of 2002, the party has gained both publicity and electoral support by focusing the question of “integration of immigrants” in terms of assimilation and intensified demands aimed at the “immigrant Others”. In this article, the party’s recent developments in the area of integration policy is analysed within the framework of two general processes in contemporary politics, the politics of racialisation and the medialisation of politics. The party’s successful interventions in the area of integration policy are built on an intimate as well as complex interplay between racialisation and medialisation. The agenda articulated by the party, further, has several similarities with the agenda of “authoritarian populist” movements throughout Europe.

Sedan 1990- talet har de offentliga organisationerna genomgått flera stora förändringar som medfört att enhetschefer inom den kommunala verksamheten fått ökat ansvar och befogenheter, vilket gör enhetschefsrollen mer komplext. Rapporter visar på svårigheter att rekrytera och behålla chefer, därför är viktigt att undersöka hur enhetschefens arbete ska kunna utvecklas till ett mer attraktivt arbete. Ett attraktivt arbete skapas genom att ge medarbetarna bra förutsättningar inom arbetsinnehåll, arbetstillfredsställelse, samt arbetsförhållanden. I chefsyrket ingår tre roller varav en är medarbetarrollen som enligt teorin inte är speciellt prioriterad eller synliggjord. Studiens syfte är att identifiera vad som gör enhetschefyrket till ett attraktivt arbete samt hur det kan utvecklas. I studien har en kvalitativ forskningsmetod används för att uppnå en djupare förståelse kring enhetschefernas arbetssituation. Detta har bidragit till att ett hermeneutiska synsätt valts, då vi strävar efter att få en ökad förståelse. Studien genomfördes på Falu kommun, där sex enhetschefer inom omvårdnadsförvaltningen intervjuades. Resultatet visar att enhetscheferna är tillfredsställda med sin arbetssituation och upplever arbetet som attraktivt. Faktorer som varierande, handlingsfrihet, problemlösning, sociala kontakter och delar av erkänsla hör till attraktivitetsfaktorer i yrket. Enhetscheferna beskriver tre utvecklingsområden för att öka attraktiviteten. Det första innefattar ledarskapet i organisationen där brister förekommer inom kommunikation och planering. Andra utvecklingsområdet handlar om arbetstakten genom att individanpassa arbetsgruppernas storlek samt tid för reflektion och återhämtning. Tredje utvecklingsområdet enhetscheferna belyser är bristen på erkänsla från organisationen. Utöver enhetschefernas brister har vi identifierat ytterligare ett utvecklingsområde för att öka attraktiviteten. Under intervjuerna har det framkommit att det råder stor avsaknad av kollegor att "bolla idéer" med vilket i sin tur medför att arbetet upplevs som ensamt. För att motverka ensamheten är chefsgruppshandledning ett alternativ, där reflektion och feedback ingår. Forskningen visar att detta även leder till ökad självkänsla, engagemang.

For the Swedish poet, essayist and aphorist Vilhelm Ekelund, ensamhet (solitude) and gemenskap (intellectual and spiritual community) were highly complex notions, with various and often contradictory meanings. In this article, I argue that both concepts have positive as well as negative connotations in Ekelund’s texts. Solitude can be sweet and delightful and the poet/writer may long for it, but it can also appear to him as a sordid and painful state. In the same way, life with other people may be just as difficult and complicated. I show that Ekelund as a young poet both embraced solitude as a positive notion and suffered from depressing isolation. The theme of solitude also appeared in his early prose as a heroic stance fitting for an extraordinary person. According to Ekelund, the fate of the truly gifted artist is loneliness, and he will find great difficulties connecting with people around him. In fact, he will find intellectual and spiritual community only when communicating with the great precursors – in Ekelund’s case that meant the prominent figures of Greek and Roman cultural heritage. “Modern” artists interested him only in so much as they openly venerated this classicist tradition. Ekelund may have despaired at the idea of an intellectual or spiritual community with his contemporaries; he was, nevertheless, optimistic regarding the ability of later generations to understand him. He was convinced that he did not write for people in his own time but, indeed, for posterity.

Stora idrottsevenemang är till stor del beroende av de intäkter som kommer från sponsrandeföretag. Inför skid-VM i Falun 2015 startade organisationen Beyond Skiing Foundation ABett projekt i form av ett sponsornätverk. Projektet kom att kallas Beyond Skiing och syftet varatt försöka locka regionala- företag, kommuner och organisationer att sponsra skid-VM.Tanken med sponsornätverket var att ge ett värde till projektets medlemmar som ville varamed och sponsra skid-VM, men som inte ville betala den summa pengar som krävdes för attbli huvudsponsorer till evenemanget.Syftet med denna undersökning är att förklara varför en heterogen grupp sponsorer utspriddaöver en stor region ingick i ett regionalt sponsornätverk. Urvalet bestod av medlemmarna iBeyond Skiing. Vidare gjordes ett urval att medlemmarna skulle vara lokaliserade i Dalarna,men utanför Falun. Anledningen till varför regionala sponsorer utan direkt geografiskkoppling till Falun valdes, var att kopplingen mellan deras sponsring av skid-VM kan påförhand ses som mer komplex och onaturlig jämfört med sponsorer från Falun, eftersomsponsring i mindre skala tenderar att röra samarbeten med sponsrade enheter inom samma ort.Data till studien samlades in genom fem kvalitativa telefonintervjuer. Resultatet indikerar påatt medlemmarna i Beyond Skiing hade tydliga kommersiella mål med sin sponsring av skid-VM och att sponsra endast genom goodwill var i detta fall mindre förekommande. Studien harvisat att sponsringssamarbetes specifika erbjudanden och regionala motiv har varit tvåbidragande orsaker till varför sponsorerna ville sponsra skid-VM. Särskilt nöjda varsponsorerna med nätverksträffarna som Beyond Skiing Foundation anordnade förmedlemmarna inom Beyond Skiing.

The power of homosociality: how young men “do” masculinity in groups and individually Using young men’s narratives, about other men, friends, dates and girlfriends, this article discusses the following questions: Can the interpretation – the understanding of young men’s collective presentations of masculinity as a surface that hides a more complex masculinity – undermine how we interpret young men’s talk about and interaction with other men, as well as with women? Can this disassembling understanding have an impact on how young men interpret and relive the interactions with other men, as well as with women? Can this disassembling of the homosocially created masculinity from the more individually created masculinity shape secondary gains for the young men, such as e.g. a more flexible and stretchable arena of responsibility, as well as more flexible space of acting? Thomas Johansson, Professor of Social Work social work, states that if we only focus the homosocially created masculinity, this will reshape a less nuanced picture of young men’s way of doing masculinity (Johansson 2005). Thus, young men’s vulnerability and difficulties remain hidden. However, this disassembling of the homosocially created masculinity from the more individually based doings of masculinity could possibly also give secondary gains, such as e.g. a more flexible and stretchable field of responsibility, as well as more flexible space of acting. This article shows that using a fragmentised and situated masculinity, as a way of understanding the complexity and the ambivalence in young men’s project of doing masculinity, makes evident – on the one hand – the vulnerability in young men’s process of doing masculinity. On the other hand, however, this view also makes it possible for young men to avoid responsibility for their actions. Instead the situated context – e.g. if in a peer group or alone, and what kind of relations the young man has – will be significant for how the act will be interpreted. The empirical material consists of six individual interviews and one group interview with four men. The age span of the participants is 16 to 24 years old. The overall theme for the discussions is heterosexual practice and relations.

This dissertation is a case study dealing with a school development project that took place in an upper secondary school as a result of a merger of two schools with different cultures. The project used a method called “Frirumsmodellen” and was planned to be conducted in three steps. The first was to carry out a cultural analysis in order to map the preconditions to start a school development project. The second was to carry out concrete actions and finally study eventual effects from such activities by doing a second cultural analysis. My role was to be a supervisor in the school development work, but at the same time study how this work was conducted and its impact in the ordinary school day. The dissertation takes its departure in the fact that schools are political governed. The mission of schools is never neutral; it is always an expression of behind laying social forces, ideologies and ideals of the contemporary society. Of this reason, there is a close connection between the macro political level and the micro political level. Another point of departure is the transition from a modern to a post modern society that gives the character to the changes that take place in schools. Steering of schools has partly been treated as a technical implementation problem. Schools contain on going conflicts between different interest groups that, more or less regularly, end up in educational reforms. These reforms generate school development activities in the single school. Undoubtedly, this makes school development to a complex process. At a rather late stage of the study I decided not to fulfil my task to follow the original plan. I instead let the school development project as a model to be in focus. The over all purpose was formulated: How is it possible to understand what happened in the school development project in the Falkgymnasiet and why was it not possible to carry it out as it was said in the project plan? To interpret what took place during the project I did create an interpretation frame of implementation and complexity theory that also made it possible to critically scrutinise the “Frirumsmodellen”. Already in an early stage of the process it was obvious that the “Frirumsmodellen” did not supply any tools to use and it became disconnected from the project. The project in it selves was marginalised and made invisible. The headmaster used the situation to change things she thought were important to develop. As a result, things happened, but most of the involved people did not at first hand connect this to the project. It is, of course, difficult in detail to say what caused what. The complexity theory successively made the hidden patterns revealed, hidden unofficial potentates visible, as well as unpredictable conditions that generated reactions from the personnel in front of a development work. Together this was rather efficient obstacles for not changing this school. I also discuss school development and implementation problems on a general level, for example, the possibility to transform a top-down initiated project to be bottom-up driven and using project as a tool for school development work. It was obvious that headmasters and teachers must be prepared to handle the ideological dimensions of problems schools have to face. Consequently, development work is about making problems visible and to handle these in the intersection point between the intentions of educational policies, pedagogical researchers, school administrators, headmasters, teachers and pupils. The ideological dimension also contains an existential issue. Do I as a teacher share the intentions for the development work? If not, how must I act?

Det mobila operativsystemet Android är idag ett ganska dominerande operativsystem på den mobila marknaden dels på grund av sin öppenhet men också på grund av att tillgängligheten är stor i och med både billiga och dyra telefoner finns att tillgå. Men idag har Android inget fördefinierat designmönster vilket leder till att varje utvecklare får bestämma själv vad som ska användas, vilket ibland kan leda till onödigt komplex kod i applikationerna som sen blir svårtestad och svårhanterlig. Detta arbete ämnar jämföra två designmönster, Passive Model View Controller (PMVC) och Model View View-Model (MVVM), för att se vilket designmönster som blir minst komplext med hjälp av att räkna fram mätvärden med hjälp av Cyclomatic Complexity Number (CCN). Studien är gjord utifrån arbetssättet Design & Creation och ämnar bidra med: kunskap om vilket mönster man bör välja, samt om CCN kan peka ut vilka delar i en applikation som kommer att ta mer eller mindre lång tid att testa. Under studiens gång tog vi även fram skillnader på om man anväder sig av den så kallade Single Responsibilyt Principle (SRP) eller inte. Detta för att se om separerade vyer gör någon skillnad i applikationernas komplexitet. I slutändan så visar studien på att komplexiteten i små applikationer är väldigt likvärdig, men att man även på små applikationer kan se skillnad på hur komplex koden är men också att kodkomplexitet på metodnivå kan ge riktlinjer för testfall.

Bakgrund: Patientens rätt att vara delaktig i planering och genomförande av sin vård betonas idag, men många patienter är mindre delaktiga än de önskar vara. Det finns många fördelar med att patienten är delaktig. Syfte: Att beskriva vilka faktorer som påverkar patientens delaktighet i omvårdnad från patientens och sjuksköterskans perspektiv inom somatisk slutenvård. Metod: Litteraturstudie baserad på 16 vetenskapliga artiklar, publicerade mellan åren 2006 och 2015. Sökning skedde i databaserna PubMed och CINAHL, samt i de funna artiklarnas referenslistor. Resultat: Fem kategorier med faktorer som påverkade patientens delaktighet i omvårdnad identifierades; kunskap, relationen mellan patienten och sjuksköterskan, sjuksköterskans förhållningssätt, patientens situation och egenskaper samt organisationen. Slutsats: Faktorerna inom de fem kategorierna utgör ett komplicerat samspel och varje patient är en unik person med egna önskemål och preferenser för delaktighet.

The recent advances in CMOS technology have allowed for the fabrication of transistors with submicronic dimensions, making possible the integration of tens of millions devices in a single chip that can be used to build very complex electronic systems. Such increase in complexity of designs has originated a need for more efficient verification tools that could incorporate more appropriate physical and computational models. Timing verification targets at determining whether the timing constraints imposed to the design may be satisfied or not. It can be performed by using circuit simulation or by timing analysis. Although simulation tends to furnish the most accurate estimates, it presents the drawback of being stimuli dependent. Hence, in order to ensure that the critical situation is taken into account, one must exercise all possible input patterns. Obviously, this is not possible to accomplish due to the high complexity of current designs. To circumvent this problem, designers must rely on timing analysis. Timing analysis is an input-independent verification approach that models each combinational block of a circuit as a direct acyclic graph, which is used to estimate the critical delay. First timing analysis tools used only the circuit topology information to estimate circuit delay, thus being referred to as topological timing analyzers. However, such method may result in too pessimistic delay estimates, since the longest paths in the graph may not be able to propagate a transition, that is, may be false. Functional timing analysis, in turn, considers not only circuit topology, but also the temporal and functional relations between circuit elements. Functional timing analysis tools may differ by three aspects: the set of sensitization conditions necessary to declare a path as sensitizable (i.e., the so-called path sensitization criterion), the number of paths simultaneously handled and the method used to determine whether sensitization conditions are satisfiable or not. Currently, the two most efficient approaches test the sensitizability of entire sets of paths at a time: one is based on automatic test pattern generation (ATPG) techniques and the other translates the timing analysis problem into a satisfiability (SAT) problem. Although timing analysis has been exhaustively studied in the last fifteen years, some specific topics have not received the required attention yet. One such topic is the applicability of functional timing analysis to circuits containing complex gates. This is the basic concern of this thesis. In addition, and as a necessary step to settle the scenario, a detailed and systematic study on functional timing analysis is also presented.

We propose several new metrics to describe the complex ownership structure of business groups, and provide simple formulas and algorithms to compute these metrics. We use these measures to describe in detail the ownership structure of Korean chaebols in the period of 2003 to 2004. In addition, we validate the usefulness of our new metrics by showing empirically that they are important for understanding the valuation and performance of group firms. In particular, we show evidence that firms that are central to the control structure of the chaebol (central firms), firms in cross-shareholdings, and firms that are placed at the bottom of the group (i.e., with lower ultimate ownership) have lower profitability than other group firms. The valuation results suggest that central firms and firms in cross-shareholding loops have lower valuations than other public Chaebol firms. The lower valuation of these firms is not explained by variation in measures of ownership concentration and separation between ownership and control.
