- Design in general, including participatory design, has been and is still closely entangled with an idea of progress molded by modernism, technological development, rationality and economic growth. Today, when trying to shift towards other motivations and meanings in designing, we as designers find ourselves being haunted by this legacy. In this workshop we invite participants to make present and carefully untie designs’ entanglements with progress and to craft concrete imaginaries of a more socio-ecological just design after progress. Through this workshop we hope to start building a community around present-ing design histories and making a repertoire of narratives of how to be better haunted in participatory design.The workshop will take the form of a séance that is based on stories and images from the participants’ ongoing work that speaks to where they have sensed a haunting by the ghosts of progress embedded in design. This could for example be in a design method that you are using, a learning objective in your design curricula, an evaluation criterion, a design outcome that you have been involved with as a professional design practitioner, design educator or design researcher.It is imperative that the participants are in agreement with the workshop organisers that the séance is in itself an experimental attempt to explore a non-linear way of searching for the barely present or not easily discernible ideals or mechanisms of progress in participatory design. It is not to be confused with calling for supernatural spirits or deceased kins.

Acute effects of vibration on thermal perception thresholds
- 2006

Konferensbidrag (refereegranskat)abstract
- Objective This study focuses on the acute effects of vibration and how vibrations influence the measures of the thermal perception thresholds during different vibration magnitudes, frequencies, and durations.Methods The fingers of ten healthy subjects, five males and five females, were exposed to vibration under 16 conditions with a combination of different frequency, intensity and exposure time. The vibration frequency was 31.5 and 125 Hz and exposure lasted between 2 and 16 min. The energy-equivalent frequency weighted acceleration, according to ISO 5349-1, for the experimental time of 16 min was 2.5 or 5.0 m/s(2) (r.m.s.), corresponding to a 8-h equivalent acceleration, A(8) of 0.46 and 0.92 m/s(2), respectively. A measure of the thermal perception of cold and warmth was conducted before the different exposures to vibration. Immediately after the vibration exposure the acute effect was measured continuously on the exposed index finger for the first 75 s, followed by 30 s of measures at every minute for a maximum of 10 min. If the subject's thermal thresholds had not recovered, the measures continued for a maximum of 30 min with measurements taken every 5 min.Results For all experimental conditions and 30 s after exposure, the mean changes of the thresholds compared with the pre-test were found to be 0.05 and -0.67C for the warmth and cold thresholds, respectively. The effect of the vibration exposure was only significant on the cold threshold and only for the first minute after exposure when the threshold was decreased. The warmth threshold was not significantly affected at all. The frequency and the exposure time of the vibration stimuli had no significant influence on the perception thresholds for the sensation of cold or warmth. Increased equivalent frequency weighted acceleration resulted in a significant decrease of the subjects' cold threshold, not the warmth. The thresholds were unaffected when changes in the vibration magnitude were expressed as the frequency weighted acceleration or the unweighted acceleration.Conclusion When testing for the thermotactile thresholds, exposure to vibration on the day of a test might influence the results. Until further knowledge is obtained the previous praxis of 2 h avoidance of vibration exposure before assessment is recommended.

Lessons from the Regulation of E-scooters through the MDS Standard: Policy Lessons for Connected Vehicles
- 2023
-
Ingår i: Proceedings of the 56th Hawaii International Conference on System Sciences. - : IEEE. - 9780998133164

Konferensbidrag (refereegranskat)abstract
- Connected vehicles generate new data streams that present promising opportunities for policymakers to monitor and learn from events and behavior. To explore what we can learn from how public entities leverage ubiquitous data streams for policy development and enforcement, we draw on a case study of the standard Mobility Data Specification (MDS) and its use by cities to regulate E-scooter operators. Our findings suggest that (1) the richness of real-time data changes the speed of policy revision, (2) data access enables moving some micro-decisions to the edge, and (3) policy will be formulated as fixed or flexible with different amendment rules.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In this article, we describe the research and societal needs as well as ongoing efforts to shape Swedish as a Second Language (L2) infrastructure. Our aim is to develop an electronic research infrastructure that would stimulate empiric research into learners’ language development by preparing data and developing language technology methods and algorithms that can successfully deal with deviations in the learner language.

Studying Power and Knowledge in the Technology Classroom: Towards a Conceptual Framework
- 2014
-
Ingår i: BERA Annual Conference 2014.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper reports on an empirical exploration of the constitution of power and knowledge in science and technology (S&T) classrooms. A deepened examination of the teaching of S&T is partly motivated by high status of these subjects in society, how they are portrayed as crucial both for the individual, in order to function in an increasingly technologically advanced society, and for the society at large, while finding it increasingly difficult to attract interest among the youth. The aim of this paper is to develop and illustrate the use of a conceptual framework for exploring how power relations are constituted in the technology classroom – in terms of what Foucault (1982/2002) conceptualises as ‘actions upon actions’ (p. 340) – by the research questions: 1) How are teacher actions communicating how and what knowledge is privileged in the classroom? 2) How is this knowledge privileging establishing power relations, in terms of possibilities for student actions? The conceptual framework makes use of practical epistemological analysis (Wickman & Östman 2002) as an analytical tool for describing teacher actions that involves a privileging of a certain educational content. Furthermore, it also utilises an adaptation of Brousseau’s (1997) concept ‘didactical contract’ that includes a Foucauldian conceptualisation of power. The empirical design relies on a purposive sampling of classrooms, documenting classroom activities using video recordings. This paper will illustrate the use of the conceptual framework, by an analysis of a case of three lessons in one Swedish technology classroom in grade 8. The topic of these lessons concerns solid and stable constructions. The pupils work in smaller groups with construction of bridges, a very common activity when working with this topic in Swedish classrooms. The first stage of the analysis focuses the actions initiated by the teacher, through the identification of epistemological moves (Lidar et al. 2006), such as instructional or confirming moves. In a second stage, the analysis focuses on how these ‘moves’ are functional in constituting a ‘didactical contract’, that is ‘the (specific) set of behaviours of the teacher which are expected of the students and the set of behaviours of the student which are expected by the teacher’ (Brousseau & Warfield 1999, p. 47). In summary, we argue that the investigation of how power and knowledge interrelate in moment-to-moment interactions in the classroom may provide additional clues to how micro-inequalities, adding up to patterns of exclusion in S&T (Rosser 2012), occur in the classroom context.

Exemplifying different methodological approaches of analysing textbooks in mathematics
- 2022
-
Ingår i: The relation between mathematics education research and teachers' professional development. - Göteborg : Svensk förening för MatematikDidaktisk Forskning - SMDF. - 1651-3274. - 9789198402452 ; 16, s. 125-129, s. 125-129
-
Konferensbidrag (refereegranskat)abstract
- In this symposium, we will discuss different ways of analysing mathematics textbooks from a methodological point of view. The discussion will be based on examples from five separate ongoing analyses of Swedish textbooks divided into two methodological approaches; one where analysis is conducted within an established theoretical framework, and one where analytical tools are constructed through combining aspects of different theories. The symposium will be held at the conference MADIF-13.
