- A common research process in visualization is for visualization researchers to collaborate with domain experts to solve particular applied data problems. While there is existing guidance and expertise around how to structure collaborations to strengthen research contributions, there is comparatively little guidance on how to navigate the implications of, and power produced through the socio-technical entanglements of collaborations. In this paper, we qualitatively analyze reflective interviews of past participants of collaborations from multiple perspectives: visualization graduate students, visualization professors, and domain collaborators. We juxtapose the perspectives of these individuals, revealing tensions about the tools that are built and the relationships that are formed — a complex web of competing motivations. Through the lens of matters of care, we interpret this web, concluding with considerations that both trouble and necessitate reformation of current patterns around collaborative work in visualization design studies to promote more equitable, useful, and care-ful outcomes.

- Visualization research methods help us study how visualization systems are used in complex real-world scenarios. One such widely used method is the interview — researchers asking participants specific questions to enrich their understanding. In this work, we introduce the pair-interview technique as a method that relies on two interviewers with specific and delineated roles, instead of one. Pair-interviewing focuses on the mechanics of conducting semi-structured interviews as a pair, and complements other existing visualization interview techniques. Based on a synthesis of the experiences and reflections of researchers in four diverse studies who used pair-interviewing, we outline recommendations for when and how to use pair-interviewing within visualization research studies.

Tidskriftsartikel (refereegranskat)abstract
- Two-neutrino double electron capture (2νECEC) is a second-order weak-interaction process with a predicted half-life that surpasses the age of the Universe by many orders of magnitude. Until now, indications of 2νECEC decays have only been seen for two isotopes, 78Kr and 130Ba, and instruments with very low background levels are needed to detect them directly with high statistical significance. The 2νECEC half-life is an important observable for nuclear structure models and its measurement represents a meaningful step in the search for neutrinoless double electron capture—the detection of which would establish the Majorana nature of the neutrino and would give access to the absolute neutrino mass. Here we report the direct observation of 2νECEC in 124Xe with the XENON1T dark-matter detector. The significance of the signal is 4.4 standard deviations and the corresponding half-life of 1.8 × 1022 years (statistical uncertainty, 0.5 × 1022 years; systematic uncertainty, 0.1 × 1022 years) is the longest measured directly so far. This study demonstrates that the low background and large target mass of xenon-based dark-matter detectors make them well suited for measuring rare processes and highlights the broad physics reach of larger next-generation experiments.

Past and Future Embedded in the Present : A Cultural History of a Local Shopping Street
- 2018
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Most of the literature accumulated around retail change derive a linear, progressive understanding, typically coined with the term “retail evolution”. Once it is formulated as such, a need for adopting a historical perspective to study present becomes superfluous, because the past is understood as something that is left behind, something incapable of making an impact on the present. In this research, taking a local shopping street, it is showed that present is an assemblage of different material and sensorial layers of past and imagined futures, and the street’s retail history has had a fluctuating, non-linear, circular and accumulative character. Likewise, it has been in dynamic relationship with cultural manifestations of consumers, and also their shopping performances. Södergatan is the main shopping street of the stigmatized district Söder in Helsingborg, a middle-size city in south Sweden. Söder was established as a working-class district in the mid 19th century, and thereby Södergatan functioned as a retail geography primarily serving the needs of the working-class families living in the area. Starting from the1910s, gradually, more modern retail formats, such as department stores, supermarkets, and national and international chain stores made an entrance, which enabled novel ways of shopping. After the 1980s, along with global trends, independent retailers and service stores expanded in the retail geography once again, this time it was transcultural migrant entrepreneurs who run the retail places. Finally, in the last couple of years, a number of new construction and renovation projects have been initiated in Söder, including a high-class hotel, a bohemian art gallery, and renovation of the old local shopping mall to upscale experience and residential center, which facilitated multiple future scenarios.The study is based on analysis of written and visual historical documents, and visual ethnographic research conducted on consumers’ shopping performances on the street.

Praxitopia : Co-constituting a vibrant local street through shopping
- 2021
-
Konferensbidrag (refereegranskat)abstract
- In the last decades shopping’s spatiotemporal manifestations are changed radically in conjunction with proliferation of car usage, internationalization of retail sector, and construction of out-of-town malls (Wrigley & Lowe, 1996; Mansvelt, 2005; Kärrholm & Nylund, 2011; Aslan & Fredriksson, 2017). However, the main empirical focus laid mostly on the mainstream and spectacular geographies of shopping; there is little literature on how shopping is enacted in “other” retail geographies, and how these geographies are co-constituted through enactments of shopping (cf. Jones et al., 2007; Rabikowska, 2010; Hall, 2012; Findlay & Sparks, 2012; Kuppinger, 2014; Carmona, 2015; Zukin et al., 2016; Clossick, 2017). Södergatan, a local shopping street in the ‘superdiverse’ southern part of Helsingborg, Sweden, was chosen as a case study for the study, which aims to contribute to the literature on retail geographies from sociocultural perspectives, through studying how enacted modes of shopping shape a local street into a lively urban space. The study draws on “practice theory”, which supplies a profound conceptual vocabulary and dynamic epistemological gaze for concentrating on shopping as the main analytical unit (Schatzki, 1996, 2019; Schatzki et al., 2001; Reckwitz, 2002; Warde, 2005, 2014; Shove et al., 2012). In order to grasp the enmeshed character of shopping in the street, complicated by cultural, spatial, temporal, material, and sensorial layers, video ethnography is employed as the umbrella research method (Pink, 2007). The research shows that there are some major modes of shopping that are enacted in the street; framed and analysed as convenience shopping, social shopping, shopping-in-destination, alternative shopping, and budget shopping. It is also shown that this mix of modes of shopping, bundling with each other, co-constitute the street into a meaningful and vibrant part of the city, by interacting with the shopping street’s sensomateriality in the states of engagement formulated as “onness”, “throughness”, “withness”, and “inness”, as well as entangling with its spatiotemporality in the directions of interrelation of “verticality”, “horizontality”, “circularity”, and “linearity”.

Praxitopia : How shopping makes a street vibrant
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- During recent decades, shopping’s geographical manifestations have altered radically and the presumed ‘death’ of town centre retailing has become a public concern. The social, cultural, and economic backgrounds of this decentralisation of retail and its effects on city life have been studied comprehensively. However, to date, few studies have examined the changing dynamics of non-mainstream shopping geographies, particularly local shopping streets. How shopping is enacted in such places, and shopping’s part in shaping them, has been largely overlooked. Aspiring to fulfil this knowledge gap, this dissertation examines shopping activities on Södergatan, a local shopping street in a stigmatized ‘super-diverse’ district of Helsingborg, Sweden known as Söder, and contributes to the literature on shopping geographies by drawing on a sociocultural perspective.The study draws on practice theory and focuses on shopping as the main unit. The analysis is built on a sensitivity to the interrelationships existing between social practices and place, emerging from the epistemic positioning resulting from the identification of 'modes of practices'. In order to grasp the enmeshed character of shopping, which is complicated by cultural, spatial, temporal, material, and sensorial layers, video ethnography was employed as the primary research collection method, in combination with go-along interviews, observation and mental-mapping.The research reveals five major modes of shopping practice which jointly represent a typology for understanding shopping in terms of being enacted in the street; i.e. convenience shopping, social shopping, on-the-side shopping, alternative shopping, and budget shopping. This thesis also shows that the bundling of these modes of shopping shapes the street into a vibrant part of the city by interrelating with the shopping street’s sensomaterial and spatiotemporal dimensions in complex and multifaceted directions. Consequently, the local shopping street is conceptualized as a praxitopia, a place co-constituted through social practices.
