Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This booklet is a report for a case study visit during four day field trip, a group of nine PhD students and their supervisors – all part of the National Research School for Architecture and Planning in the Urban Landscape, APULA – set out to explore what may be considered the outback of Western Europe’s conurbations, the transnational region of Kiruna -Narvik.Both “remote” and “resourceful”, “threatened” and “thriving” (equally relative notions), this region seemed to offer possibilities to reflect upon many of the current tendencies influencing contemporary planning practice and research.

Tidskriftsartikel (refereegranskat)abstract
- Background-Thrombus aspiration is still being used in a substantial number of patients despite 2 large randomized clinical trials showing no favorable effect of routine thrombus aspiration during primary percutaneous coronary intervention in patients with STsegment- elevation myocardial infarction. The aim of this observational study was to evaluate the impact of thrombus aspiration on mortality, stent thrombosis, and stroke using all available data from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR). Methods and Results--We identified 42 829 consecutive patients registered in SCAAR between January 2005 and September 2014 who underwent percutaneous coronary intervention for ST-segment-elevation myocardial infarction. Thrombus aspiration was used in 25% of the procedures. We used instrumental variable analysis with administrative healthcare region as the treatmentpreference instrumental variable to evaluate the effect of thrombus aspiration on mortality, stent thrombosis, and stroke. Thrombus aspiration was not associated with mortality at 30 days (risk reduction: -1.2; 95% confidence interval [CI] , -5.4 to 3.0; P=0.57) and 1 year (risk reduction: -2.4; 95% CI, -7.6 to 3.0; P=0.37). Thrombus aspiration was associated with a lower risk of stent thrombosis both at 30 days (risk reduction: -2.7; 95% CI, -4.1 to -1.4; P < 0.001) and 1 year (risk reduction: -3.5; 95% CI, -5.3 to -1.7; P < 0.001). In-hospital stroke and neurologic complications did not differ between groups (risk reduction: 0.1; 95% CI, -0.8 to 1.1; P=0.76). Conclusions--Mortality was not different between the groups. Thrombus aspiration was associated with decreased risk of stent thrombosis. Our study provides important evidence for the external validity of previous randomized studies regarding mortality.

- Measurements of DNA ploidy can be performed either with image cytometry (ICM) or flow cytometry (FCM); both methods provide independent prognostic information in primary breast cancer. The aim of the present investigation was to compare the two methods and to relate the findings to prognosis (median follow-up 42 months). Concordance in ploidy status (diploid, tetraploid, aneuploid) was obtained in 76% of the samples (168/222). When the fraction of S-phase cells (SPF) from FCM analysis was also taken into consideration, four different groups of samples were obtained (Flow I-IV), which were considered to correspond to the Auer classification (Auer I-IV) of DNA histograms obtained from image cytometry. Complete concordance between the two techniques now was 70% (155/222). Samples classified as Flow I (diploid or near-diploid with low SPF) and Auer I had a distant metastasis rate of 3/60 (5%), as compared to 62/154 (40%) for all other combinations of the Flow and Auer classifications taken together. Thus, the only findings of prognostic importance were that some samples were Flow I but not Auer I, or vice versa. These two groups represent 17 (7.7%) and 14 (6.3%), respectively, of the total number of samples, and had frequencies of distant metastasis similar to those of the other high-risk groups, namely, 7/17 and 5/14, respectively. In a multivariate analysis, flow cytometric S-phase value was a stronger prognostic factor than either the Flow and Auer classification. We conclude that when routine FCM DNA analysis is used, diploid or near-diploid samples with a low S-phase value should be reanalyzed with ICM.

Proposed EU Regulations’ Impact on Data Utilisation– A Multi-Case Study within Public Transport
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Motivation: In a broad sense data sharing onboard public transport vehicles is governed by two different business models – interoperable and free of charge access for some data versus data that is restricted to specific uses by commercial contracts and existing legislation. Under the Digital Decade the EU has proposed new legislation with the ambition to promote a single digital market. The question then arises – how will the upcoming regulations affect existing business models for data utilisation?Method: We have investigated two different cases where existing technology meets upcoming EU legislation. The questions have been framed through dialogue with actors in the industry, to cover topics and questions that are both concrete and current. Using the policy lab methodology, we have investigated the possibility to re-use surveillance film from public transport vehicles for passenger counting. The analysis compares GDPR and the Swedish camera surveillance act with the proposed AI Act, to see what new possibilities or obstacles arise. We have also explored the changes that the Data Act may impose on different actors’ access to data derived from the batteries installed in an electric bus.Results: The AI Act will not change the business models within the eco-system but facilitate access to more personal data (including personal data where GDPR otherwise would be a barrier), useful for training automated passenger counting. Those responsible for placing the system on the market will still need to ensure that they are compliant with GDPR in terms of processing personal data. In terms of the Data Act the outcome is more disruptive as the owner and user of a vehicle is entitled to all data representing their usage, free of charge, and this will impair existing business models for data access. It is also possible for multiple actors to be users, for instance if the vehicle is owned by a public transport authority and leased by an operator.Discussion: Our analysis shows that while the impact of the Data Act can resonate with the ambitions behind the regulation in terms of making more data interoperable and available free of charge, it can also have the opposite effect. The latter is specifically the case where altruistic data sharing already is in place and the Data Act imposes standard contracts for and role-based restrictions towards utilisation. Both the AI Act and the Data Act are complex and often difficult to assess. In relation to the Data Act, the recitals were helpful for interpreting the application of articles and definitions. For understanding the relationship between the AI Act and GDPR we combined the legal analysis with prototyping the impacts and relied on sharing insights with other actors. This highlights the need for multiple ways of performing the data collection and analysis as well as the suitability of policy labs as a research method

Bokkapitel (refereegranskat)abstract
- The fact that the debate concerning copyright in a digital society has been both intense and filled with polemic conflicts ever since the late 1990s makes it clear that it is a most complicated issue to solve, or even grasp. Basically, both the legal and societal discussion and development are explicitly dependent on a greater understanding of the on-going processes surrounding copyright. This presents a well-suited point of departure for research such as the one conducted within the Cybernorms research group – both in terms of providing valuable insights into the field of sociology of law when it comes to understanding how to relate to the framework provided by digitalization in general and the Internet in particular, and in terms of providing more accurate knowledge and toolsets to legislators in related fields.

- Efter en tid av hemlöshet har Kungl. Konsthögskolans examensutställningar tagit det utrymda biblioteket i Ellen Keys huset i besittning. På Kungl. Konsthögskolan strävar vi efter att, likt Key, ställa individens egna idéer och behov i centrum istället för att pressa in dem i en strömlinjeformad utbildningsmall.

- Gait disorders are a relevant factor for falls and possible to measure with wearable devices. If a wearable sensor can detect differences in gait parameters between fallers and non-fallers has not yet been studied. The aim of this study was to measure and compare gait parameters, vestibular function, and balance performance between fallers and non-fallers among a group of older persons. Participants were senior members (n = 101) of a Swedish non-profit gymnastic association. Gait parameters were obtained using an inertial measurement unit (IMU) that the participants wore on the leg while walking an obstacle course and on an even surface. Vestibular function was assessed by the Head-shake test, the Head impulse test, and the Dix-Hallpike maneuver. Balance was assessed by the Timed Up and Go, the Timed Up and Go manual, and the Timed Up and Go cognitive tests. Falls during the 12-month follow-up period were monitored using fall diaries. Forty-two persons (41%) had fallen during the 12-month follow-up. Fallers had more limited ability to vary their gait (gait flexibility) than non-fallers (p < 0.001). No other differences between fallers and non-fallers were found. The use of gait flexibility, captured by an IMU, seems better for identifying future fallers among healthy older persons than Timed Up and Go or Timed Up and Go combined with a cognitive or manual task.
