Stability and leptogenesis in the left-right symmetric seesaw mechanism
- 2007

Journal article (peer-reviewed)abstract
- We analyze the left-right symmetric type I+II seesaw mechanism, where an eight-fold degeneracy among the mass matrices of heavy right-handed neutrinos M-R is known to exist. Using the stability property of the solutions and their ability to lead to successful baryogenesis via leptogenesis as additional criteria, we discriminate among these eight solutions and partially lift their eight-fold degeneracy. In particular, we find that viable leptogenesis is generically possible for four out of the eight solutions.

Challenges in project management : Grabbing the elephant
- 2007
-
In: Projects & Profits. ; 7:12, s. 33-37
-
Journal article (peer-reviewed)abstract
- Projects and project management tend to have special meanings to the individuals involved in a specific line of research. This article reports on some topics covered in an informal Swedish network devoted to study project management. Ten topics are selected for discussion that fall into three broad categories—projects as practice, productivity in projects and education in a PM curriculum.

Discretized gravity in 6D warped space
- 2007
-
In: Nuclear Physics B. - : Elsevier BV. - 0550-3213 .- 1873-1562. ; 278:1-3, s. 32-63
-
Journal article (peer-reviewed)abstract
- We consider discretized gravity in six dimensions. where the two extra dimensions have been compactified on a hyperbolic disk of constant curvature. We analyze different realizations of lattice gravity on the disk at the level of an effective field theory for massive gravitons. It is shown that the observed strong coupling scale of lattice gravity in discretized five-dimensional flat or warped space can be increased if the latticized fifth dimension is wrapped around a hyperbolic disk that has a non-trivial warp factor. As an application, we also study the generation of naturally small Dirac neutrino masses via a discrete volume suppression mechanism and discuss briefly collider implications of our model.

Development of Virtual Teams and Learning Communities
- 2005
-
In: Recent Research Developments in Learning Technologies. - Badajos, Spain : Formatex Research Center. ; , s. 1184-1189
-
Conference paper (peer-reviewed)abstract
- Students of an Internet based course in project management worked during a 20 week period in teams of 4-6 persons. The course consisted of Swedish students living in Sweden or abroad which made it impossible for many of the teams to have any face-to-face interaction. During the course the teams were assigned to a series of discussion questions and cases. The study, based on a survey of 287 students who participated in the course, examined their experience of teamwork and showed that many of the classical team development issues also evolve in a virtual team. Furthermore, the study showed that students considered their teamwork was efficient and that being able to communicate, discuss and share experiences was essential for developing a positive learning community.

Project as practice : making project research matter
- 2006
-
In: Proceedings of IRNOP VII project research conference. - Beijing : China Publishing House of Electronics Industry. - 712103252X ; , s. 540-549
-
Conference paper (peer-reviewed)abstract
- Project theory is not only an immature field of research, it is insubstantial when it comes to understanding what is really going on in projects. This paper contributes to making project research matter to the academic as well as the practitioner through the theoretical development of a project-as-practice approach, aligned with an ongoing debate in social science research. We outline the framework of project-as-practice and argue that there are two major challenges to the researcher: the relevance challenge and the pattern challenge. We suggest how these challenges can be met and give some examples of earlier studies that have done so. The practice approach is not a substitute to present theorizing but rather a complement that brings substance. Finally, underlying notions of the practice approach are outlined in order to have a fruitful future development of a project-as-practice approach that makes project theory matter!

Avvikelsens mekanismer : Observationer av projekt i praktiken
- 2009
-
Doctoral thesis (other academic/artistic)abstract
- Bakgrund I det närmaste alla organisationer strävar efter att använda sina resurser så effektivt som möjligt. Vad som dock inte diskuterats i någon större utsträckning är att den starkt kopplade komplexa organisationen inte klarar av att bemöta ens den minsta avvikelsen utan att ägna den direkt uppmärksamhet. Den övergripande frågan är därför Hur hanteras avvikelser i starkt kopplade projekt? Det teoretiska ramverket är först och främst projektlitteratur men ramverket vidgas sedermera till att omfatta praktikansatslitteratur samt Weicks (1976) ”Loosely coupled systems”. Metod Givet ansatsen faller det sig naturligt att göra en fallstudie med observationer som huvudsaklig metod. Utöver tolv veckors observationer förlitar jag mig på 57 intervjuer och mängder av dokument. En organisation, två projektgrupper och 118 avvikelser observerades totalt under perioden. De data som samlades in analyserades med hjälp av dataprogrammet Nvivo. Resultat Analysen är uppdelad i tre integrerade kapitel. Det första kapitlet diskuterar avvikelser som företeelse och definierar begreppet närmare. En avvikelse definieras som en händelse som kräver såväl identitet som handlingskraft. Det andra analyskapitlet analyserar praktiken närmare. Allt som allt observerades 29 praktiker vilka kunde grupperas i åtta praktikmönster. Praktikmönstren kunde sedermera inordnas i två distinkta löskopplingsmönster i en teoretiskt underbyggd och empiriskt styrkt figur. Figuren och följaktligen praktikmönstren beskriver hur avvikelsen görs löst kopplad. Det tredje analyskapitlet diskuterar fem mekanismer som följer av med de löst kopplade avvikelserna. Dessa fem mekanismer kan sedermera betonas och utnyttjas av projektledaren. Slutsatser Slutsatserna följer två spår. Det ena spåret fokuserar på projekt i allmänhet och projektledning i synnerhet. Slutsatsen som kan dras där är att det finns en inneboende osäkerhet i projekt som kan utnyttjas för att hantera avvikelser. Alla avvikelser har inte stora konsekvenser men de besitter vissa gemensamma egenskaper. Det andra spåret är ett bidrag till teorin om löst kopplade system. Länge har en processuell och praktikbaserad studie saknats. Genom att undersöka löskopplingsprocesser i ljuset av en praktikansats har jag visat hur löskopplingsprocesser ser ut.
