- This paper identifies different university spin-off (USO) roles related to resource interaction among business parties. It does so by mapping how USOs become part of business networks in terms of their roles relative to other parties. The theoretical frame of reference focuses on roles and resource interaction based on an industrial network approach to business markets. The empirical research is based on five cases of USOs representing a variety in terms of technology, degree of newness, sector, and area of application. As a result of the analysis, three different roles are identified: the USO as resource mediator, resource re-combiner and resource renewer. These roles reflect how USOs adapt resources to, or require changes among, business parties' resources. The paper also discusses the main resource interfaces associated with the three roles and related challenges. The paper contributes to previous research through illustrating USOs' roles relative to business parties from a resource interaction point of view, and by pointing to the establishment of new companies in business networks as a way of implementing innovation. Finally, the paper discusses the managerial implications of the research in terms of the USO's need to understand which role to take and how to develop it.

Anatomy of a 21st-century sustainability project: The untold stories
- 2020
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- What does a sustainability project look like in the 21st century? Not the glossy version, but the naked truth? Tired of manicured, over-theorised accounts of the ‘musts’ and ‘shoulds’ of sustainability transitions, we got to the bottom of things; actually, to the very bottom of the project hierarchy: the individual. Our point of departure is that projects are nothing but temporarily interconnected people. This means that if we don’t know what people do and what they think about their work, we will never be able to create a deeper understanding of the project, its rationale and future impact. Making use of the autoethnographic method, this book provides critical insights into what it’s like being part of a 21st-century project. Building on unfiltered first-hand contributions from 73 authors representing the five organs of a project’s anatomy – the brain (theoreticians), the skeleton (leaders), the limbs (strategists), the heart (local stakeholders) and the lungs (researchers) – the book covers all the important aspects of contemporary project-making: (1) projectification as a societal phenomenon; (2) sustainability as the main project buzzword; (3) transdisciplinarity as a hot working method; (4) economy as the invisible project propeller; (5) space as the contextual project qualifier; (6) gender and integration as the obstinate orphans of project-making; (7) trends as the villains of thoughtless project mimicry; (8) politics as the “necessary evil” of projects; and (9) knowledge production as the cornerstone of all project work. The book ends with an extensive critical analysis of what makes a project tick and how to avoid project failure. We infer that talking about project outcomes and impacts is just that… talking. What makes a difference is what can be done to the project in itself. Three important virtues – the ABC of project-making – emanate from this book’s 40 chapters: building good relationships (Affinity), having the guts to make a change (Bravery), and showing willingness to learn (Curiosity). These are the basis for the successful execution of future sustainability projects, where complexity, unpredictability and desperation will become a staple force to recon with. The original contribution of this book is to shed light on the silent triumphs and hidden pathologies of everyday project-making in an effort to elevate individual knowledge to a level of authority for solving the wicked – yet project-infused – problems of our time.

Energy and exergy analysis of a cruise ship
- 2018

Tidskriftsartikel (refereegranskat)abstract
- In recent years, the International Maritime Organization agreed on aiming to reduce shipping’s greenhouse gas emissions by 50% with respect to 2009 levels. Meanwhile, cruise ship tourism is growing at a fast pace, making the challenge of achieving this goal even harder. The complexity of the energy system of these ships makes them of particular interest from an energy systems perspective. To illustrate this, we analyzed the energy and exergy flow rates of a cruise ship sailing in the Baltic Sea based on measurements from one year of the ship’s operations. The energy analysis allows identifying propulsion as the main energy user (46% of the total) followed by heat (27%) and electric power (27%) generation; the exergy analysis allowed instead identifying the main inefficiencies of the system: while exergy is primarily destroyed in all processes involving combustion (76% of the total), the other main causes of exergy destruction are the turbochargers, the heat recovery steam generators, the steam heaters, the preheater in the accommodation heating systems, the sea water coolers, and the electric generators; the main exergy losses take place in the exhaust gas of the engines not equipped with heat recovery devices. The application of clustering of the ship’s operations based on the concept of typical operational days suggests that the use of five typical days provides a good approximation of the yearly ship’s operations and can hence be used for the design and optimization of the energy systems of the ship.

- 1989 was a turning point within the socio-economic development in the former Eastern bloc, initiating a system transformation that affected the society at large. It also contributed to the crystallisation of certain cultural landscapes, hitherto largely illegible due to the inhibition of spatial processes encountered during Communism. In Poland, after a quarter-century of free market economy, the focus on social problems began to expand to the spatial realm as well. It became apparent that the progressive social polarisation that followed was most prominent in environments striated by a particular landscape type – the former State Agricultural Farm (PGR). Considering PGRs “the epitome of rurality” subject to ideas informing the direction of contemporary “rural development” prompts a different way of looking at the problem. In this paper, we investigate the concept of rurality in the discursive tenor of implemented policy and contrast it with contextualised empirical examples. Our findings suggest that efficient policy should be confronted with the expectations of residents at the local level, while introducing top-down actions usually ends in failure as in the case of post-PGR estates.

The potential role of forest management in Swedish scenarios towards climate neutrality by mid century

- Swedish climate policy targets net zero greenhouse gases (GHG) by mid-century, with road transport independent of fossil fuels by 2030, requiring far-reaching changes in the way energy is used. Forest management is expected to support carbon sequestration and provide biomass for various uses, including energy. In this paper, we combine two energy scenarios with four forest scenarios and quantify GHG balances associated with energy-use for heat, electricity, and road transport, and with forest management and production, use, and end-of-life management of various forest products, including products for export. The aggregated GHG balances are evaluated in relation to the 2-degree target and an allocated Swedish CO2 budget. The production of biofuels in the agriculture sector is considered but not analyzed in detail.The results suggest that Swedish forestry can make an important contribution by supplying forest fuels and other products while maintaining or enhancing carbon storage in vegetation, soils, and forest products. The GHG neutrality goal is not met in any of the scenarios without factoring in carbon sequestration. Measures to enhance forest productivity can increase output of forest products (including biofuels for export) and also enhance carbon sequestration. The Swedish forest sector can let Sweden reach net negative emissions, and avoid “using up” its allocated CO2 budget, thereby increasing the associated emissions space for the rest of the world.

The concept of 'rural' as a psychosocial process: From concept attainment to concept unlearning
- 2019

Ingår i: Quaestiones Geographicae. - : Adam Mickiewicz University Poznan. - 2081-6383 .- 0137-477X .- 2082-2103. ; 38:4, s. 15-28

- Realising that human geography has been defined less by its canonical works but rather by its canonical concepts, the current status of the concept 'rural' puts a question mark over progress in human geography in terms of how well we have been able to adapt knowledge to reciprocate with societal change at large. As one of the oldest geographical concepts still in widespread use, 'rural' stands in stark contrast to the immense changes encountered by the society during the last century, let alone decades. And while this problem has been approached both empirically and philosophically, not enough stress has been put on the cognitive and sociological processes that have governed the attainment and retention of 'rural' in science, and beyond. In this vein, the aim of this paper is to provide a structured argument for facilitating a view of 'rural' less as a geographical space and more as a concept purportedly thought to define such space by way of inculcation.

Tidskriftsartikel (refereegranskat)abstract
- Yellow pea and faba bean are potential candidates to replace soybean-based ingredients due to their suitability for cultivation in the northern hemisphere, non-genetically modified organisms cultivation practice and low risk of allergenicity. This study examined the functionality of local yellow pea and faba bean protein isolates/concentrate as meat analogue products. The most critical factors affecting the texture properties of meat analogue were also determined. Extrusion was used to produce high-moisture meat analogues (HMMAs) from yellow pea and faba bean protein isolates/concentrates and HMMAs with fibrous layered structures was successfully produced from both imported commercial and local sources. The texture properties of the HMMA produced were mainly affected by the ash, fiber and protein content and water-holding capacity of the source protein. Three extrusion process parameters (target moisture content, extrusion temperature, screw speed), also significantly affected HMMA texture. In conclusion, functional HMMA can be produced using protein isolates derived from locally grown pulses.

Image Reconstruction in Microwave Tomography Using a Dielectric Debye Model
- 2012
-
Ingår i: IEEE Transactions on Biomedical Engineering. - 0018-9294 .- 1558-2531. ; 59:1, s. 156 - 166

Tidskriftsartikel (refereegranskat)abstract
- In this paper, quantitative dielectric image reconstruction based on broadband microwave measurements is investigated. A time-domain-based algorithm is derived where Debye model parameters are reconstructed in order to take into account the strong dispersive behavior found in biological tissue. The algorithm is tested with experimental and numerical data in order to verify the algorithm and to investigate improvements in the reconstructed image resulting from the improved description of the dielectric properties of the tissue when using broadband data. The comparison is made in relation to the more commonly used conductivity model. For the evaluation, two examples were considered, the first was a lossy saline solution and the second was less lossy tap water. Both liquids are strongly dispersive and used as a background medium in the imaging examples. The results show that the Debye model algorithm is of most importance in the tap water for a bandwidth of more than 1.5 GHz. Also the saline solution exhibits a dispersive behavior but since the losses restrict the useful bandwidth, the Debye model is of less significance even if somewhat larger and stronger artifacts can be seen in the conductivity model reconstructions.
