- BACKGROUND: The aim was to study the clinicopathological characteristics, treatment, and outcome of liposarcoma in an unselected, population-based patient sample, and to establish whether treatment was according to the Scandinavian Sarcoma Group (SSG) treatment guidelines. METHODS: The SSG Pathology Board reviewed 319 liposarcoma cases reported between 1986 and 1998. After the review, 237 patients without metastasis were analyzed for local recurrence rate in relation to surgical margins, radiotherapy, occurrence of metastasis, and survival. RESULTS: Seventy-eight percent of the patients were primarily operated on at a sarcoma center, 45% with wide margins. All patients operated on outside the center had nonwide margins. Low-grade lesions constituted 67% of cases. Despite nonwide surgery, only 58% of high-grade lesions were treated with postoperative radiotherapy. The risk of local recurrence after nonwide surgery, without irradiation, was 47% for high-grade lesions. The estimated 10-year, local recurrence-free and metastasis-free survival in the low-grade group was 87% and 95%, respectively. In the high-grade group, it was 75% and 61%, respectively. Independent adverse prognostic factors for local recurrence were surgery outside a sarcoma center and histological type dedifferentiated liposarcoma. For metastases, they were old age, large tumor size, high grade, and histological type myxoid liposarcoma with a round cell component. Radiotherapy showed significant effect on local recurrence rate for the same grade and margin. CONCLUSIONS: Patients with liposarcoma should be treated at specialized centers. Postoperative radiotherapy decreases the local recurrence rate. To maintain quality and provide support for further trials, reporting to quality registers is crucial.

Spotify teardown : inside the black box of streaming music
- 2019
-
Bok (refereegranskat)abstract
- An innovative investigation of the inner workings of Spotify that traces the transformation of audio files into streamed experience. Spotify provides a streaming service that has been welcomed as disrupting the world of music. Yet such disruption always comes at a price. Spotify Teardown contests the tired claim that digital culture thrives on disruption. Borrowing the notion of "teardown" from reverse-engineering processes, in this book a team of five researchers have playfully disassembled Spotify's product and the way it is commonly understood. Spotify has been hailed as the solution to illicit downloading, but it began as a partly illicit enterprise that grew out of the Swedish file-sharing community. Spotify was originally praised as an innovative digital platform but increasingly resembles a media company in need of regulation, raising questions about the ways in which such cultural content as songs, books, and films are now typically made available online. Spotify Teardown combines interviews, participant observations, and other analyses of Spotify's "front end" with experimental, covert investigations of its "back end." The authors engaged in a series of interventions, which include establishing a record label for research purposes, intercepting network traffic with packet sniffers, and web-scraping corporate materials. The authors' innovative digital methods earned them a stern letter from Spotify accusing them of violating its terms of use; the company later threatened their research funding. Thus, the book itself became an intervention into the ethics and legal frameworks of corporate behavior.

Konferensbidrag (refereegranskat)abstract
- The Electric Solar Wind Sail (E-sail) is a novelpropulsion concept that enables faster space travel tomany solar system targets. E-sail uses charged solarwind particles as the source of its propulsion. This isachieved by deploying long, conducting and chargedtethers, which get pushed by the solar wind byCoulomb drag [1].E-sail technology is being developed to technicalreadiness level (TRL) 4-5 by the European Union’sSeventh Framework Programme for Research andTechnological Development, EU FP7, in a projectnamed ESAIL (http://www.electric-sailing.fi/fp7).Prototypes of the key parts are to be produced. Thedesign will be scalable so that a real solar winddemonstration mission could be scaled up from them.We review here the latest results of the constantlyevolving E-sail project.

A pathway for parking in line with the Paris Agreement
- 2022
-
Ingår i: Case Studies on Transport Policy. - : Elsevier BV. - 2213-624X. ; 10:2, s. 1223-1233

Tidskriftsartikel (refereegranskat)abstract
- Current European parking policies do not seem to steer towards a future where urban transport meets the climate goals. Prominent in current housing and parking policies are the so-called minimum parking standards. Recent research has shown that they contribute to increased car use and consequently to higher CO2 emissions. This is because they contribute to urban sprawl, extensive land use, increased housing and infrastructure construction costs, and that they restrict the number of flats per urban land unit. Other recent research shows that the construction of underground garages causes considerable CO2 emissions. This paper is based on previous research on the development of the transport sector to be in line with climate targets (i.e., the Paris Agreement). It intends to fill a research gap regarding how parking management can be designed to be consistent with these targets. Through a future study approach with Stockholm as a case example, this paper illustrates a policy shift in parking policies considered to be in line with national climate targets. The article presents concrete indicators to quantify the scope of change needed (e.g., removing 60,000 residential parking spaces and providing vehicle sharing with 7,500 cars and at least 7,500 bikes). The focus shift goes from providing physical parking spaces to providing satisfactory mobility and accessibility. We outline a pathway towards a future scenario of parking and mobility in Stockholm, with a combination of mobility services, parking restrictions (e.g., cap on parking spaces, removal of minimum parking standards), and citizen participation. The pathway is also analysed regarding equity, feasibility, and acceptance.

A Shift in Urban Mobility and Parking? : Exploring Policies in Relation to Practices
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The transport sector is associated with many environmental challenges, including carbon dioxide (CO2) emissions. Research indicate that CO2 emissions should decrease by at least 50 % per decade in order to be in line with the Paris Agreement, and the transport sector is highlighted as a particularly challenging sector. Sweden, which is the case study in this thesis, has a goal of reducing CO2 emissions from the transport sector with 70 % between 2010 and 2030. This target is, however, not likely to be met if current trends continue. New technology will probably not be enough to reach the target, and car ownership and car travel will probably also have to decrease. Furthermore, many households do not have access to cars, and do not benefit from policies that facilitate car use and car ownership. The purpose of this thesis is to critically analyse policy measures on parking and mobility in metropolitan areas in Sweden with the aim of being in line with the CO2 emission goals set by the Paris Agreement, as well as investigating how the aims of the Paris Agreement can be met with a backcasting study. All studied policy measures highlight the need to shift focus from physical infrastructure to accessibility. In each case, however, current practices and conditions render a transition more difficult. The first paper in the thesis studies the Swedish Transport Administration (STA) mandate to finance different measures. The STA states the importance of reducing the need to travel and making more efficient use of existing infrastructure, and stipulates that these types of measures should be considered before new infrastructure investments. However, the STA has a limited mandate to finance measures with the aim of reducing the need to travel, which results in ambiguous signals to, and frustration among, regional STA officials. This paper demonstrates that making the STA’s mandate more function-oriented would facilitate a transition in line with the sustainable mobility paradigm.The second policy measure discussed in this thesis is the shift from minimum parking requirements, where developers are obliged to build a minimum number of parking spaces in order to obtain a building permit, to flexible parking requirements, where the number of parking spaces provided depends on the local context, and where other mobility services may replace the need for parking. The second paper in this thesis follows two blocks of flats built with flexible parking requirements. Car ownership has decreased in both blocks of flats, and car use has decreased in one of the blocks of flats. Furthermore, car sharing membership and use have increased considerably. However, the process of leaving a car dependent social practice is slow and the conditions (e.g. the technology; and ways of finding, booking, and paying for services) need to be relatively stable for the practice to grow. Other policies may also be needed for emerging social practices to grow. Some of these policies have been implemented in Stockholm (e.g. congestion charges, on-street parking fees, extension of public transport and bicycle infrastructure). However, there is also a trend in the opposite direction; such as new urban highways. Future interventions could be made open to residents in adjacent properties, if more people are to be attracted to the mobility services. The third paper in this thesis discusses the feasibility of using a new parking management tool; “Parking Benefit Districts”, in a European context (Stockholm, Sweden). In a Parking Benefit Districts program, on-street parking charges are implemented, increased or extended, and the resulting revenues are returned to the areas where the charges were imposed. Citizens, or other stakeholders, then participate in deciding how to use these revenues. The underlying intention is to increase acceptance of parking charges, as on-street parking charges may be considered necessary by city planners but are unpopular among citizens and other stakeholders. This thesis shows that there are no legal barriers to implementing a Parking Benefit District programme in Sweden, but there are some limitations as to how revenues can be used. Moreover, Sweden does not have this planning tradition and the programme may not be perceived as legitimate. Another important issue is equity and participation, e.g. it is important to consider who to include and how to include them.The fourth paper is a target-oriented backcasting study. The paper depicts a future image for parking and mobility for the city of Stockholm that is in line with the CO2 emission goals in the Paris Agreement, and then examines how to plan for parking and mobility in order to steer towards this future image. The paper points out that current parking standards (the flexible parking standard discussed in Paper II) is far from being in line with the Paris Agreement, and emphasizes the necessity of a different planning approach. The paper also presents a path of development thought to be in line with the Paris Agreement.
