PublicationA Characterisation of Ambiguity in BPM( 2023)
;Hugo A. Lopez ;Andrea Burattin ;Luciano Garcia BanuelosBusiness Process Management is concerned with processrelated artefacts such as informal specifications, formal models, and event logs. Often, these process-related artefacts may be affected by ambiguity, which may lead to misunderstandings, modelling errors, non-conformance, and incorrect interpretations. To date, a comprehensive and systematic analysis of ambiguity in process-related artefacts is still missing. Here, following a systematic development process with strict adherence to established guidelines, we propose a taxonomy of ambiguity, identifying a set of concrete ambiguity types related to these process-related artefacts. The proposed taxonomy and ambiguity types help to detect the presence of ambiguity in process-related artefacts, paving the road for improved processes. We validate the taxonomy with external process experts.Type: conference contribution -
PublicationA digital assistant for healthcare providers targeting 10 to 15-year-old patients with asthma and their family: results from a pilot study(Center for Digital Health Interventions, 2019-10-05)
;Harperink, Samira ;Dittler, Ullrich ;Xiao, Grace ;Stanger, Catherine ;Oswald, HelmutMoeller, AlexanderBackground: Asthma is one of the most common chronic conditions worldwide. Successful asthma management requires knowledge about the condition, treatment adherence, and behavioral skills. In addition, when treating children with asthma, a trustful and empathetic collaboration between healthcare providers, patients and their family is necessary for successful asthma management. However, resources of healthcare providers are limited to few face-to-face consultations, and personal support in the everyday life of chronic patients is not feasible. Digital assistants may overcome this challenge, because they are computer programs that imitate human interactions and can be designed to support healthcare providers in reaching out to patients in their everyday lives. Until now, however, it has not been clear whether digital assistants would be adopted by healthcare providers, patients or supportive family members and whether they could have a positive impact on the management of asthma in children. Objective: The goal of this project was to develop and test an empathetic digital assistant for healthcare providers that targets 10 to 15-year-olds with asthma and a supportive family member. Method: The digital assistant MAX was collaboratively designed by healthcare providers, young patients, a media didactician, a clinical psychologist and computer scientists. MAX communicated with all relevant stakeholders along a pre-defined intervention schedule, i.e., with healthcare providers via email, with patients via a mobile chat app and with a family member via SMS. The 14 lessons focused on asthma knowledge (e.g., what to do in case of an asthma attack), treatment adherence (i.e., discussion of medication plans), and behavioral skills (i.e., inhalation and breathing techniques). A family member was requested to actively participate in seven lessons. Healthcare providers were requested to assess patients’ inhalation technique based on video clips recorded by a family member. A pilot study was carried out to assess reach, impact, therapeutic alliance, technical feasibility and acceptability of MAX. Reach was measured by the proportion of patients approached and those who started to interact with MAX. Impact was assessed via a pre-post asthma knowledge test of a validated asthma quiz and by the number of inhalation mistakes made after healthcare providers gave their feedback. Therapeutic alliance between MAX and patients was assessed by the Session Alliance Inventory. Finally, technical feasibility and acceptance of MAX were evaluated by patients’ adherence, the number of technical shortcomings, and qualitative feedback gathered from healthcare providers, patients and family members. The study was approved by the first author’s institutional review board. Results: Overall, 99 children with asthma were screened by healthcare providers at 6 study sites (4 hospitals and 2 local Swiss Lung Association sites, a home care provider for integrated care in Switzerland) between January and April 2019. Overall, 49 (49.5% of those screened) young patients (33 male, 27 iOS and 22 Android users) with an average of 12 years (SD=1.54) fulfilled all inclusion criteria (i.e., asthma diagnosis, 10 to 15 years old, German-speaking, smartphone available, interested in investing ca. 4h of their time, supportive family member with smartphone access), and started to interact with MAX. Thirty-nine (79.6%) patients who completed Lesson 2 indicated that they had lived with asthma for 5.61 years (SD=4.17) and 13 (30%) reported that they were uncertain about how to manage their asthma. The average completion rate of the 49 participants regarding the 14 MAX lessons was 80.4%, and 37 (75.5%) patients completed all lessons in 3 weeks. A paired t-test with the baseline observation carried forward showed that asthma knowledge had increased significantly from the first lesson until the last lesson with a large effect (d=0.91). Out of 192 random lesson assessments, patients indicated 86 times (44.8%) that they learned a lot, 73 times (38.0%) that they learned some new aspects and 33 times (17.2%) that they already knew everything about asthma. The technical quality of all 42 inhalation video clips was good, and it took healthcare providers ca. 118s to assess each video clip. Patients received feedback on their inhalation technique within 1.9 days through a second chat channel of the MAX app dedicated to communication with their healthcare provider. On average, healthcare providers identified 1 inhalation mistake in each video clip, and 3 serious inhalation mistakes were identified and corrected in a second video clip. Out of 275 lessons, patients indicated 269 times (97.8%) that they were supported by family members in collaborative exercises. Only 74 (0.5%) of all chat interactions took place in the chat channel dedicated to healthcare provider communication whereas 15’087 (99.5%) interactions took place in the scalable chat channel with MAX. Therapeutic alliance was rated very high by the patients, who also enjoyed using the mobile app and stated they wanted to continue working with MAX. The young patients also found the MAX app easy to use and reported that it offered clear benefits. Overall, MAX was assessed very positively by all relevant stakeholders, and several suggestions for improvement and technical barriers, particularly related to the technical infrastructure in the participating hospitals, were provided (e.g., lack of easy WIFI access to patients or access to state-of-the-art browser technology for healthcare providers). Conclusion: Digital assistants for healthcare providers targeting 10 to 15-year-old patients with asthma and a family member have the potential to improve asthma knowledge, treatment adherence, and behavioral skills. The reach of such interventions is limited by the technical infrastructure of healthcare providers. Future work should assess the impact of digital assistants on asthma outcomes.Type: conference contribution -
PublicationA Mimetic Theory of User Behaviors in Online Communities: A Computational Study of GitHub( 2023-08-01)
;Michael GauYoungjin YooOnline communities are virtual communities where users exchange knowledge, organize tasks, and accomplish work. We focus on how individual users influence the ways others behave. We draw from mimetic theory and leverage computationally intensive theorizing to examine the influence of popular developers on other developers in GitHub, the largest and most popular open source software development community. Analyzing a subsample of 324 projects, we find that the behavior of rockstars –i.e. exceptionally popular developers– is imitated by other developers, and thus strongly influences overall work patterns in projects. We further find that this effect is stronger when a rockstar is more active in a project. Our findings offer important contributions for research on online communities, specifically by shedding light on the significant role that individual actors can have in such communities. Crucially, to our knowledge, our study offers the first empirical evidence that online communities actually change user behaviors through memetic processes.Type: conference contribution -

PublicationA Social-Topography of Art Basel: Hierarchies in the Global Art Market( 2013-10-03)The paper applies Pierre Bourdieu's theory of interactions between socially and physically acquired space to Art Basel, which, as the "Art Olympics", represents the wealthiest sector of the art world in terms of symbolic and economic capital, and is generally considered the most important art fair. Art Basel represents a temporal and spatial concentration of the global art market. Here the hierarchies, positions and structures of the field of the galleries are reflected in the "(An)Ordnung" (Löw): in the configuration of the boxes allocated by the exhibition management and thereby reproduced. The struggle not only for the around 300 exhibitor spaces, but also for the most prestigious locations at the exhibition itself, is outlined by the actors on site in qualitative interviews. At Art Basel, "front row" galleries benefit from their exclusive location, which also helps to generate symbolic capital. Inequality in terms of symbolic capital is reinforced through the inequalities of placing themselves in attractive locations in the space. Galleries "on the fringes" are allocated their space due to their limited capital resources, and at the same time this space results in less opportunity of generating symbolic capital. An initial analysis of Art Basel 2012 shows that galleries from certain countries are able to generate "profit from space" (Bourdieu). The "prime positions" around the circular courtyard are mainly occupied by galleries from the United States and Switzerland. More generally, the centres and peripheries of the global art field are reflected at Art Basel. Through the process of correspondence analysis, these connections are indicated systematically. In addition, qualitative interviews with gallery owners and a questionnaire are incorporated into the social-topographical analysis at Art Basel.Type: conference contribution

PublicationAligning Strategies: How Digital Health Technologies Are Used by a Swiss Insurance Company to Foster a Sustainable Healthcare Landscape( 2024)
;Alina Luisa Liebich ;Livia JacobEscalating healthcare costs, as well as an outdated traditional healthcare landscape, are placing considerable strain on European healthcare systems, pushing society to re-evaluate current business models. Sustainable solutions require stakeholders to collaborate and innovate. For this Position Paper, we interviewed a representative of SWICA, one of Switzerland’s largest health insurance companies, to gain insight into their perspective and expectations regarding the upcoming challenges. The results show that SWICA has developed a portfolio of multiple digital health technologies to promote an integrated and preventive care approach in collaboration with new partners in the healthcare system.Type: conference contributionJournal: Proceedings of the 17th International Joint Conference on Biomedical Engineering Systems and Technologies -
PublicationAmbivalent alternatives: Male managers struggling with their support for gender equality( 2023-09-15)In this talk I am aiming at furthering our understanding of men’s roles, but also the struggles, challenges and ambivalences involved when becoming change agents in equality initiatives. Analysing how men talk about gender equality in ten group discussions with male managers in five companies in Switzerland, I show that they are both invested in gender equality and as well critical about hegemonic masculinity. However, being critical of face time, full-time work, and the ideal of the heroic leader does not result in disengaging from hegemonic masculinity or an actual positioning as alternative men. Rather, the discussions end in silence and a general feeling of helplessness.Type: conference contribution

PublicationAn Event-Centric Metamodel for IoT-Driven Process Monitoring and Conformance Checking( 2023-09)Process monitoring and conformance checking analyze process events describing process executions. However, such events are not always available or in a form suitable for these analysis tasks, for example for manual processes and (semi-)automated processes whose executions are not controlled by a Process-Aware Information System. To bridge this gap, we propose to leverage Internet of Things (IoT) technologies for sensing low-level events and abstracting them into high-level process events to enable process monitoring and conformance checking. We propose an event-centric metamodel for monitoring and conformance checking systems that is agnostic with respect to process characteristics such as level of automation, system support, and modeling paradigm. We demonstrate the applicability of the metamodel by instantiating it for processes represented by different modeling paradigms.Type: conference contributionJournal: 21st International Conference on Business Process Management (BPM) Workshops

PublicationAn Object-centric Approach to Handling Concurrency in IoT-aware Processes( 2023-09)
;Florian Gallik ;Yusuf KirikkayisManfred ReichertThe increasing adoption of IoT in the context of Business Process Management (BPM) makes it necessary to efficiently coordinate concurrent processes and activities that involve physical resources. Traditional approaches to handling concurrency in BPM systems are not suitable for automating IoT-aware processes due to novel challenges raised by the IoT. We propose to handle concurrency in IoT based on objectcentric processes implemented in the PHILharmonicFlows framework. The framework facilitates the data-driven modeling and coordination of object lifecycles and interactions, which are suitable to address concurrency in IoT-aware processes. The approach is demonstrated in a scenario from smart manufacturing. The results show that PHILharmonicFlows offers a flexible and comprehensible solution for coordinating concurrent activities in IoT settings with constrained physical resources.Type: conference contributionJournal: 21st International Conference on Business Process Management (BPM) Workshops
