The Swedish security policy has changed from stressing neutrality to embrace co-operation within the EU and other organisations. New threats like terrorism, boarder-crossing criminality and natural disasters require new ways to deal with this type of problems to protect the society. Since the beginning of 21st century the high Russian economic growth has made it possible for the country to play an increasingly role as a superpower on the international political stage. In the same time the democratic development has been replaced by an autocratic rule which has obstructed the Russian- European relations. From a Swedish security policy view the Russian political development is of importance and the picture of Russian as a threat has changed from 1996 to 2008/09.

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

Syftet med studien ?r att unders?ka hur omsorg till?mpas f?r att fr?mja l?rande och utveckling f?r elever inom anpassad grundskola som l?ser ?mnesomr?den. Det insamlade datamaterialet har analyserats tematiskt med st?d av socialkognitiv teori. Begreppet self-efficacy, ?ven kallat sj?lvtillit eller sj?lvf?rm?ga, ?r centralt inom denna teori och utg?r tillsammans med Noddings omsorgsteori k?rnan i analysen. Denna etnografiska studie bygger p? 50 timmar kvalitativa videoobservationer, tillsammans med deltagande observationer och f?ltanteckningar av den pedagogiska praktiken p? tv? anpassade grundskolor. Resultatet visar att l?rares och paraprofessionellas f?rv?ntningar p? elevernas f?rm?gor, samt hur omsorg till?mpas, har en betydande inverkan p? elevernas self-efficacy och d?rmed deras f?ruts?ttningar f?r l?rande och utveckling. I resultatet framtr?der tre perspektiv av omsorg, vilka ben?mns som fr?mjande, assisterande och h?mmande.

Syftet med denna studie har varit att fa? kunskap om vilka a?tga?rder som kan vidtas i en implementeringsprocess och lyfta fram vad som sto?djer eller hindrar att projektresultat implementeras i ordinarie verksamhet. Vi valde att formulera tre fra?gesta?llningar; Vilka a?tga?rder kan vidtas i en implementeringsprocess? Vilka faktorer sto?djer implementering? Vilka faktorer hindrar implementering? Studien har genomfo?rts pa? en kommunal arbetsrehabiliterande verksamhet som genomfo?rt ett trea?rigt ESF-projekt. Studien har genomfo?rts med hja?lp av en metodkombination besta?ende av semistrukturerade intervjuer, en deltagande observation samt dokument fra?n verksamheten och projektet.

The public sector in Sweden has in recent decades undergone a large change due to market and liberalism impact. This change has meant that marketing communication and its concepts have been adopted by administrative authorities.

Then the fire fighting properties are evaluated, including manoeuvrability and safety for users.

The main focus of this essay is to analyze whether strict employment protection legislation has a negative effect on the labour market possibilities for youth in the EU or not. To empirically examine the labour market possibilities for youth, data for unemployment rates and incidence of temporary jobs are used. By doing simple correlations between the different labour market characteristics and OECD?s employment protection legislation index the effect of the latter is tested. The result is that a tendency for youth unemployment and frequency of youth with temporary employment to be higher when employment protection legislation is strict can be seen.

A tough working climate and the lack of extrinsic motivation at workplaces within health care raise the question of what instead drives employees within this industry. A possible answer to this is Public Service Motivation (PSM) - a type of motivation that is based on the desire to do good for society and its individuals. In order to investigate this further we have performed a qualitative study consisting of ten interviews with people working with institutional care, where the purpose has been to identify the sources of motivation and determine the impact of PSM. The results show that the compassion dimension of PSM appears to be one of the most salient motivational factors. While the rest of the PSM dimensions fail to explain the level of motivation to the same extent as compassion, other factors are recognized, such as relatedness and aspects of the nature of the work itself.

Syftet med studien a?r att underso?ka psykosocial oha?lsa med utmattning i fokus utifra?n arbetsrelaterade faktorer, konflikt mellan arbete och familj och ko?n hos la?kare pa? ett universitetssjukhus i Sverige. Studien grundar sig pa? tva?rsnittsdata fra?n projektet Health and Organisation among University hospital Physicians in Europe (HOUPE), da?r arbetsrelaterad oha?lsa bland la?kare pa? ett universitetssjukhus studerats.

Problem: Hur påverkas medarbetarnas attityd av högteknologiska förändringar? Hur påverkar implementeringen av ett högteknologiskt system kundnöjdheten bland resenärer?Syfte: Syftet med uppsatsen är att utreda om ett nyligen implementerat högteknologiskt biljett- och informationssystem kan skapa värde för resenärer och medarbetare.Teori: Den teoretiska referensram som använts är kundnöjdhet, teknikbaserad självservice, tjänstekvalitet, förväntningar, förändringar, motivation och teknikmognad.Metod: Kvalitativa intervjuer med förare och en kvantitativ enkätundersökning med resenärer har genomförts. Även vissa observationer på bussar har utförts.Empiri: I empirin presenteras förarnas mest intressanta och relevanta åsikter. Enkätunderso?kningen har sammanställts i tabeller.Analys: I analysen har empirin kopplats samman och analyserats med teorin för att kunna besvara uppsatsens frågesta?llningar och syfte.Slutsats: Empirin visar att förarna överlag är missnöjda med implementeringen, detta främst för att systemet känns föråldrat och fallerar.

Studien unders?ker vad det ?r som f?r l?rarna att fr?ng? den traditionella tj?nstemannarollen f?r att bedriva aktivism p? Twitter. F?r att g? till botten med fr?gan kommer de senaste decenniernas skolreformer att utforskas s?v?l som hur l?rarens tj?nstemannaroll har p?verkats av dessa reformer. Med netnografi som metod kommer Carol Lee Bacchis problemanalys att anv?ndas f?r att med hj?lp av hur l?rarna upplever konsekvenserna av politikens implementering f?rst? de underliggande antaganden som motiverat reformerna och ?ven dess implikationer.

Att skriva sig till la?sning, ASL, a?r en metod som mer och mer anva?nds i svenska skolor. Denna metod byter ut pennan mot datorn i den tidiga la?s- och skrivinla?rningen. Eleverna la?r sig la?sa genom sitt eget skrivande.
