1. Functional Traits in Sphagnum
Sammanfattning : Peat mosses (Sphagnum) are ecosystem engineers that largely govern carbon sequestration in northern hemisphere peatlands. I investigated functional traits in Sphagnum species and addressed the questions: (I) Are growth, photosynthesis and decomposition and the trade-offs between these traits related to habitat or phylogeny?, (II) Which are the determinants of decomposition and are there trade-offs between metabolites that affect decomposition?, (III) How do macro-climate and local environment determine growth in Sphagnum across the Holarctic?, (IV) How does N2 fixation vary among different species and habitats?, (V) How do species from different microtopographic niches avoid or tolerate desiccation, and are leaf and structural traits adaptations to growth high above the water table?Photosynthetic rate and decomposition in laboratory conditions (innate growth and decay resistance) were related to growth and decomposition in their natural habitats.

2. Samverkan på spel : Rationalitet och frustration i nätverksstyrning och svensk stadsdelsförnyelse
Sammanfattning : Grounded in a rational choice perspective, this thesis tries to develop the study of network governance. The starting point is a puzzling pattern of local multi-organizational cooperation observed in official evaluation reports on urban neighbourhood renewal in Sweden. LÄS MER
3. Spirande polisidentiteter : En studie av polisstudenters och nya polisers professionella identitet
Sammanfattning : Who am I? Who are we? And how are the two entities connected? These are key issues of this study. Socialization and other sense making processes create new social identities. One possible identity is a professional one. LÄS MER
4. The Global City 2.0 : An International Political Actor Beyond Economism?
Sammanfattning : The aim of this thesis is to increase our understanding of the Global City’s pursuit of what can be regarded as independent foreign and security policies, despite the fact that such policies have traditionally been considered to be a core function of central governments. By studying how the Global City’s role in the globalized world is constructed in local public narratives as the local government develops and pursues specific international policies, the thesis argues, we can come closer to an understanding of what it means to be and to govern a Global City, and why its local government find it to be in the city’s interest to claim international political authority.
