Activation Programs, Benefit Take-Up, and Labor Market Attachment
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Essay 1 (with Ulrika Vikman): Previous literature shows that activation requirements for welfare participants reduce welfare participation, but the dynamics behind these results have not been fully examined. In this paper we use a rich set of register data covering the entire working age population in a Swedish municipality to study how the introduction of mandatory activation programs aimed at unemployed welfare participants affect the probability of entering and exiting welfare. Our results indicate that the reduction in the number of welfare participants is mainly due to an increase in welfare exits. The effect is larger for unmarried individuals without children and for young individuals. Among the young we also find a reduction in welfare entries. It thus seems that individuals with fewer family responsibilities are more responsive to the reform.Essay 2: We study the impact of a set of labour market programs directed to unemployed welfare participants on criminal behaviour. To isolate the causal effect we exploit the sequential implementation of activation programs in municipalities and districts in Stockholm county. We find that criminal activity increased as a result of the programs. The size and significance levels of the estimates should be interpreted with caution, but we can conclude that the reform did at least not have a mitigating effect on crime. We find no evidence that the effect is larger for financially motivated crime.Essay 3: Given the trend towards more active policies on reducing the take-up of welfare benefits, the consequences of leaving welfare constitutes an important issue. This paper studies disposable income and poverty among welfare leavers in Sweden during 19 years (1990-2008). Using a rich set of register data we can accurately measure disposable income and labor market outcomes. We find that there are large significant differences in post welfare financial situation among those working full time and those who work only a little or not at all. Leavers neither working nor receiving benefits from social insurance are likely to be financially dependent on family members, and are more likely than others to be in poverty. We conclude that leaving welfare is not always associated with becoming financially better off, post welfare well being depend heavily on labor market outcomes.Essay 4 (with Matz Dahlberg and Linna Martén): In 1999, the Swedish government announced one of the largest reforms of the national defense in modern times, which led to closures and significant downsizing of several military bases, as well as large reductions of the workforce. Previous studies have found that workers that have been displaced from their previous employers experience significant earnings declines, even in the long run. In this paper we study the labor market effects of the involuntary job losses following the drastic changes of the Swedish security policy. Using population wide register data we estimate how labor income and unemployment benefit take-up changed among those employed at the affected military bases, relative to workers at unaffected military units. We find a decrease in labor earnings, primarily among civil servants. We find no effect on neither unemployment nor employment, indicating that the drop in earnings is likely to be driven by lower re-employment wages.

Adolfsbergsskolan - folkskola mitt i den mångkulturella byn
- 2001

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I tre fallrapporter från forskningsprojektet Framgångsrikt skolledarskap i olika skolkulturer presenteras resultat från omfattande empiriska undersökningar vid tre skolor. I rapporterna beskrivs och problematiseras skolornas respektive kultur: den aktuella gymnasieskolans kunskapskultur, där bildning kommit att bli ett kännetecken; den utvalda f-9-skolans karriärkultur, utsatt för ett kraftfullt förändringstryck från både elever och från den förvandling av såväl pedagogiska arbetsformer som av lärarnas arbete som nu pågår; slutligen f-6-skolan där en ursprunglig tvångskultur förvandlats till en skolkultur som betonar elevernas sociala och kulturella integration. Detta är emellertid endast bakgrunden till rapporternas egentliga fokus: undersökningen av tre välfungerande skolledares sätt att utöva skolledarskap i olika skolkulturer. Ur ett omfattande undersökningsmaterial växer tre skolledarskap fram. Här finner vi rektorn som är en kulturell insider men som förväntas utöva ett kulturförändrande ledarskap på en synnerligen traditionstyngd skola. Och visionären som har denna kulturförvandling bakom sig och som nu förväntas profilera en gymnasieskola med vikande söktal och som gör det genom att knyta an till skolans humanistiska bildningstradition. Slutligen den kommunikative skolledaren som skyr företeelsen lojalitet och som framgångsrikt lett förvandlingen av en problemtyngd skola till en folkskola mitt i den mångkulturella byn.

Adopting Open Source development tools in a commercial production environment : are we locked in?

Konferensbidrag (refereegranskat)abstract
- Many companies are using model-based techniques to offer a competitive advantage in an increasingly globalised systems development industry. Central to model-based development is the concept of models as the basis from which systems are generated, tested and maintained. The availability of high-quality tools, and the ability to adopt and adapt them to the company practice, are important qualities. Model interchange between tools becomes a major issue. Without it, there is significantly reduced flexibility, and a danger of tool lock-in. We explore the use of a standardised interchange format (XMI) for increasing flexibility in a company environment. We report on a case study in which a systems development company has explored the possibility of complementingtheir current proprietary tools with open source products for supporting their model-based development activities. We found that problems still exist with interchange, and that the technology needs to mature before industrial- strength model interchange becomes a reality.

Advances of dual source, dual-energy imaging in postmortem CT
- 2008

Tidskriftsartikel (refereegranskat)abstract
- This paper focuses on the use of multi-detector row dual-energy computed tomography (DECT) in the evaluation of postmortal examinations. The use of dual energy moves postmortem CT to an entirely new dimension of diagnostic sensitivity where contrast in the image is not merely limited to X-ray attenuation differences, but may include elements of functional and tissue characterization. This additional information may be used to improve the benefit postmortem imaging can provide to supplement and simplify the conventional autopsy. © 2008 Elsevier Ireland Ltd. All rights reserved.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Ett mycket vanligt påstående i skolforskningslitteraturen är att skolan är en synnerligen trög institution som motstår förändring. Om man däremot beger sig till en skola och talar med personalen där beskriver de mycket sällan skolan i termer av stabilitet, utan snarare att skolan är i förändring. Syftet med föreliggande text är att problematisera och försöka förstå dels dubbelheten vad gäller föreställningar om förändring i skolan, dels skolan som både trög och föränderlig institution.
