Konferensbidrag (refereegranskat)abstract
- Cross-sectoral collaboration has been touted as a solution to a range of problems in various sectors. In the construction context, public-private partnerships have recently given promises of increased productivity and innovative solutions through business models combining logics and governance structures from both the public and private sectors. Little is, however, known about how partnerships are established to combine different logics in response to competing institutional demands. Drawing on a study of a municipality's efforts to create cost efficient services, we analyse the formation of two partnerships as emerging hybrid organizations in the intersection between four institutional logics. We show how different logics are mobilized in the process of shaping the partnerships in response to the institutional pluralism and complexity they face. On this background, we discuss how the contours of two different forms of hybrid organization emerged, even though the partnerships initially operated and responded similarly to the institutional demands. We conclude that partnerships can be seen as 'trading zones' that follow different trajectories in coping with institutional demands, and hence the development of hybrid organizational forms.

- Hybrid organisations have been touted as solutions to a range of societal problems. In a construction context, strategic partnerships, as a particular type of hybrid organisation, have given promises of increased productivity and innovation through business models combining logics and governance structures from both the public and private sectors. Little is however known about how strategic partnerships are established and develop throughout their lifespan by combining different logics in response to institutional complexity. Drawing on a study of a public client’s efforts to create cost efficient services, we analyse the formation of two strategic partnerships as emerging hybrid organisations in the intersection between a market logic, a project logic, a community logic, and an administrative logic. It is shown how different logics are mobilised in the dynamic shaping of the partnerships in response to moments of institutional complexity. On this background, we discuss how the contours of two different forms of hybrid organisation emerged, even though the partnerships initially operated and responded similarly to the institutional demands. On this basis, it is concluded that strategic partnerships can be seen as “trading zones” that follow different trajectories in coping with institutional demands, and hence the development of hybrid organisational forms.

Tidskriftsartikel (refereegranskat)abstract
- This article adopts practice-based theory for understandinginter-organisational knowledge work and extends it with a discussion of the role of redundancy. In this view, a constellation of firms is a multiple configuration of communities of practices, characterised by overlappingpractises, multiple memberships and different levels of participation, and accompanied by a governance frame. The paper discusses central mechanisms for coordinating knowledge in such a complex construction project. Theknowledge relations are conceptualised through focusing on redundancy,understood as negotiated common assignment of meaning, brokers (e.g., design managers), boundary objects (e.g., drawings) and arenas (e.g., meetings). Thepaper presents an ethnographic case study of a project partnership between engineers, architects and contractors in construction using the partnering concept. The focus is on two dialogue excerpts, one on process, and one onproduct knowledge exchanges. The diversity and disjunctive feature of the practices form a condition of possibility for knowledge handling and synthesis into the built construct. Relation-based interaction is necessary with boundary objects and brokers, requisite redundancy and governance.

Konferensbidrag (refereegranskat)abstract
- The recent development of technologies, processes and methods of sustainable building has enabled anunprecedented quantum leap in the available solutions. These possibilities could be interpreted asradical, yet they appear at a time as results of a long emergent development. The aim of this paper is tocritically scrutinize, theoretically and empirically, whether radical innovation is occurring insustainable building and what the implication are.The theoretical framework is based on concepts ofradical innovation, inventions and sustainability. Radical sustainable innovation (RSI) should becharacterized by high degrees of newness in the entire life cycle. RSI should offer significantenhancements of known benefits, entirely new benefits, or substantial cost reductions, leading to thetransformation of existing markets, the creation of sustainable growth, and global sustainability. Thus,if buildings were RSI, it would be a shift in paradigm of how buildings are designed, build andused.Serious limitations on these notions are addressed. Buildings are large complex products realisedthrough complex processes and with a long lifecycle. It appears impossible that an entire buildingshould/could be radically new. How to evaluate radicality is a major challenge. It is tentativelyproposed, to use standards for sustainable office buildings. Standards are developed to accelerate thesustainable development but has to some extent come to constrain possibilities of radical innovation.As the criteria of newness is incorporated in standards, going beyond them, could be viewed as radical.Empirically a selection of international cases of office buildings with very high scores of BREEAM,LEED and DGNB are examined. Six selected cases were analysed more in detail, one ofthem,GeelensCounterflow’s Headquarters, being the most outstanding.This handful of office buildingshave reached remarkable higher level of sustainability than contemporary building regulations. Thereisindeed a gap between these few buildings and the majority, making them more radical, yet due toweak social sustainability, they are not evaluated as radical innovation.

Murmuration as metaphor for sustainable innovation processes
- 2018
-
Ingår i: Proceeding of the 34th Annual ARCOM Conference, ARCOM 2018. ; , s. 179-188
-
Konferensbidrag (refereegranskat)abstract
- The construction industry stands before an extensive and essential transition towards sustainability; however, the configuration of the innovation processes that lead to such transition is unclear. In this paper, the concept of murmuration, i.e. the collective behaviour of starlings, is introduced as a metaphor for sustainable innovation processes in construction. The murmuration metaphor captures the flowing, ever-changing non-structure that characterises innovation processes within sustainable construction. This conceptual hypothesis is based on an empirical observation, and the potentials of the metaphor are explored at two interdisciplinary workshops with actors from the Danish construction industry. The empirical validation shows that the murmuration metaphor can generate a useful framework for understanding and discussing sustainable innovation processes in construction. Furthermore, murmuration can be a fruitful addition to the understanding of the societal transition towards sustainability as an elaboration of the niche-to-regime processes emphasised in the Multi-Level Perspective.

Tidskriftsartikel (refereegranskat)abstract
- Radical innovations are essential for the sustainable transition of society; however, such innovations are struggling to establish a solid position in the ecosystem. Through a case study, the influence of the ecosystem on a radical, sustainable innovation is investigated. The study shows that the ecosystem causes bottleneck challenges for the innovation and that a lineage of exploratory projects is essential to transforming the ecosystem and thereby supporting the breakthrough of the innovation. A model for lineage ecosystem management is proposed, extending and contributing to the multiproject lineage management approach, with a particular focus on radical, sustainable innovations.

Direct observation of a ferri-to-ferromagnetic transition in a fluoride-bridged 3d-4f molecular cluster
- 2012

Ingår i: Chemical Science. - : Royal Society of Chemistry (RSC). - 2041-6520. ; 3:4, s. 1024-1032

Tidskriftsartikel (refereegranskat)abstract
- We report on the synthesis, crystal structure and magnetic characterisation of the trinuclear, fluoride-bridged, molecular nanomagnet [Dy(hfac)(3)(H2O)-CrF2(py)(4)-Dy(hfac)(3)(NO3)] (1) (hfacH = 1,1,1,5,5,5-hexafluoroacetylacetone, py = pyridine) and a closely related dinuclear species [Dy(hfac)(4)-CrF2( py)(4)]center dot 1/2 CHCl3 (2). Element-specific magnetisation curves obtained on 1 by X-ray magnetic circular dichroism (XMCD) allow us to directly observe the field-induced transition from a ferrimagnetic to a ferromagnetic arrangement of the Dy and Cr magnetic moments. By fitting a spin-Hamiltonian model to the XMCD data we extract a weak antiferromagnetic exchange coupling of j -0.18 cm(-1) between the Dy-III and Cr-III ions. The value found from XMCD is consistent with SQUID magnetometry and inelastic neutron scattering measurements. Furthermore, alternating current susceptibility and muon-spin relaxation measurements reveal that 1 shows thermally activated relaxation of magnetisation with a small effective barrier for magnetisation reversal of Delta(eff) 3 cm(-1). Density-functional theory calculations show that the Dy-Cr couplings originate from superexchange via the fluoride bridges.

Relational contracting in Nordic construction – a comparative longitudinal account of institutional field developments

Tidskriftsartikel (refereegranskat)abstract
- Purpose: Relational contracting is increasingly being applied to complex and uncertain construction projects. However, it has proved hard to achieve stable performance and industry-level learning in this field. This paper employs an institutional perspective to analyze how legitimacy for relational contracting has been produced and challenged in Denmark, Finland, Norway and Sweden, including implications for dissemination and learning. Design/methodology/approach: A collaborative case study design is used, where longitudinal accounts of the developments in relational contracting over more than 25 years in four Nordic countries were developed by scholars based in each country. The descriptions are underpinned by literature sources from research, practice and policy. Findings: The countries share similar problem perceptions that have triggered the de-institutionalization of traditional contracting practices. Models and policies developed elsewhere are important sources of knowledge and legitimacy. Most countries have seen pendulum movements, where dissemination of relational contracting is followed by backlashes when projects fail to meet projected outcomes. Before long, however, relational contracting tends to re-emerge under new labels and in slightly new forms. Such a proliferation of concepts presents further obstacles to learning. Successful institutionalization is found to rely on realistic goals in combination with broad competence development at the organizational and industry levels. Practical implications: In seeking inspiration from other countries, policymakers should go beyond contract models to also consider strategies to manage industry-level learning. Originality/value: The paper provides a unique longitudinal cross-country perspective on the field of relational contracting. As such, it contributes to the small stream of literature on long-term institutional change in the construction sector.

Randomised comparison of provisional side branch stenting versus a two-stent strategy for treatment of true coronary bifurcation lesions involving a large side branch : the Nordic-Baltic Bifurcation Study IV
- 2020
-
Ingår i: Open heart. - : BMJ Publishing Group Ltd. - 2053-3624. ; 7:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: It is still uncertain whether coronary bifurcations with lesions involving a large side branch (SB) should be treated by stenting the main vessel and provisional stenting of the SB (simple) or by routine two-stent techniques (complex). We aimed to compare clinical outcome after treatment of lesions in large bifurcations by simple or complex stent implantation.Methods: The study was a randomised, superiority trial. Enrolment required a SB >= 2.75 mm, >= 50% diameter stenosis in both vessels, and allowed SB lesion length up to 15 mm. The primary endpoint was a composite of cardiac death, non-procedural myocardial infarction and target lesion revascularisation at 6 months. Two-year clinical follow-up was included in this primary reporting due to lower than expected event rates.Results: A total of 450 patients were assigned to simple stenting (n = 221) or complex stenting (n=229) in 14 Nordic and Baltic centres. Two-year follow-up was available in 218 (98.6%) and 228 (99.5%) patients, respectively. The primary endpoint of major adverse cardiac events (MACE) at 6 months was 5.5% vs 2.2% (risk differences 3.2%, 95% CI -0.2 to 6.8, p=0.07) and at 2 years 12.9% vs 8.4% (HR 0.63, 95% CI 0.35 to 1.13, p = 0.12) after simple versus complex treatment. In the subgroup treated by newer generation drug-eluting stents, MACE was 12.0% vs 5.6% (HR 0.45, 95% CI 0.17 to 1.17, p = 0.10) after simple versus complex treatment.Conclusion: In the treatment of bifurcation lesions involving a large SB with ostial stenosis, routine two-stent techniques did not improve outcome significantly compared with treatment by the simpler main vessel stenting technique after 2 years.

Protein-altering variants associated with body mass index implicate pathways that control energy intake and expenditure in obesity
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Genome-wide association studies (GWAS) have identified >250 loci for body mass index (BMI), implicating pathways related to neuronal biology. Most GWAS loci represent clusters of common, noncoding variants from which pinpointing causal genes remains challenging. Here we combined data from 718,734 individuals to discover rare and low-frequency (minor allele frequency (MAF) < 5%) coding variants associated with BMI. We identified 14 coding variants in 13 genes, of which 8 variants were in genes (ZBTB7B, ACHE, RAPGEF3, RAB21, ZFHX3, ENTPD6, ZFR2 and ZNF169) newly implicated in human obesity, 2 variants were in genes (MC4R and KSR2) previously observed to be mutated in extreme obesity and 2 variants were in GIPR. The effect sizes of rare variants are similar to 10 times larger than those of common variants, with the largest effect observed in carriers of an MC4R mutation introducing a stop codon (p.Tyr35Ter, MAF = 0.01%), who weighed similar to 7 kg more than non-carriers. Pathway analyses based on the variants associated with BMI confirm enrichment of neuronal genes and provide new evidence for adipocyte and energy expenditure biology, widening the potential of genetically supported therapeutic targets in obesity.
