title: Designing ground truth for Machine Learning - conceptualisation of a collaborative design process between medical professionals and data scientists
Creators: name: Zajac, Hubert Dariusz

Year: 2022

description: The development of Machine Learning (ML) models is a complex process consisting of several iterative steps like problem definition, data collection and processing, feature engineering, model training, and evaluation. While the amount of research on ML model development is growing, little is known about the design process of ground truth in datasets that serve as the backbone of many ML-based systems. Design choices made before the labelling process often become invisible, and the ground truth becomes an infrastructural part of the data, which prevents it from being inspected in the event of problems at the later stages of the data science cycle. I conducted observations of the collaborative work of radiologists and data scientists on ground truth design. I report on the adopted process divided into three stages: Stage 1 - assessment of data requirements and labelling practices; Stage 2 - design and evaluation of label structure; and Stage 3 - design and evaluation of labelling tool. Moreover, I introduce two activities of Stage 2: ideation and stress test to design high-quality labels. At last, I pose outstanding questions to unpack the tensions and motivations observed during the ethnographic work.

description: This paper aims at studying the Iwasawa $λ$-invariant of the $p$-primary Selmer group. We study the growth behaviour of $p$-primary Selmer groups in $p$-power degree extensions over non-cyclotomic $\mathbb{Z}_p$-extensions of a number field. We prove a generalization of Kida's formula in such a case. Unlike the cyclotomic $\mathbb{Z}_p$-extension, where all primes are finitely decomposed; in the $\mathbb{Z}_p$-extensions we consider, primes may be infinitely decomposed. In the second part of the paper, we study the relationship for Iwasawa invariants with respect to congruences, obtaining refinements of the results of R. Greenberg-V. Vatsal and K. Kidwell. As an application, we provide an algorithm for constructing elliptic curves with large anticyclotomic $λ$-invariant. Our results are illustrated by explicit computation.

description: We present a case study on co-creating a research data infrastructure together with social policy researchers. Over three years, we investigated how the social scientists worked with data, and designed a collaborative system to support them in the harmonization, validation, exploration, and sharing of research data. We conducted several co-creation workshops, interviews, surveys, and user studies not only to co-design the system but also to assess the benefts and limitations of our participatory approach for this interdisciplinary collaboration. The evaluation uncovered that the researchers were satisfed with the processes and tools that we developed, and that the system was successfully adopted. We found that when working in a large interdisciplinary project, especially in the context of social policy research, it is critical to assess the status of the data early on, and to discuss how the group and individual goals connect with each other, to ensure long-term engagement and commitment.

description: Filamentary textures can take the form of braided, rope-like superstructures in nonlinear media such as plasmas and superfluids. The formation of similar superstructures in solids has been predicted, for example from flux lines in superconductors. However, their observation has proved challenging. Here, we use electron microscopy and numerical methods to reveal braided superstructures of magnetic skyrmions in thin crystals of B20-type FeGe. Their discovery opens the door to applications of rich topological landscapes of geometric braids in magnetic solids.

description: Redistrict, a fully integrated web interface, proposes a new platform for proximity-based public schools boundary deliberations. It has been pilot-tested on one school system in the US and aims to shift, educate, and bring visibility to policy and geographical constraints. It extends current deliberations’ state of practice, held in person or over video conference using static pdf/printed maps. This research draws knowledge from computer science, educational policy, social sciences, and geographic information systems (GIS) to allow public school officials, parents, and community at large to compute “what if ” scenarios towards a better understanding, discovery learning, and optimization when redesigning school attendance zones. We explore possible areas of improvement for the broader community to cast an informed, unique vote, while maintaining privacy, supporting ingenuity, and transparency. This speculative research prototype creates space to support a concrete path of much needed advancement in complex social deliberation using interdisciplinary research.

description: Exploring and establishing artificial neural networks with electrophysiological characteristics and high computational efficiency is a popular topic in the field of computer vision. Inspired by the working mechanism of primary visual cortex, pulse-coupled neural network (PCNN) can exhibit the characteristics of synchronous oscillation, refractory period, and exponential decay. However, electrophysiological evidence shows that the neurons exhibit highly complex non-linear dynamics when stimulated by external periodic signals. This chaos phenomenon, also known as the " butterfly effect", cannot be explained by all PCNN models. In this work, we analyze the main obstacle preventing PCNN models from imitating real primary visual cortex. We consider neuronal excitation as a stochastic process. We then propose a novel neural network, called continuous-coupled neural network (CCNN). Theoretical analysis indicates that the dynamic behavior of CCNN is distinct from PCNN. Numerical results show that the CCNN model exhibits periodic behavior under DC stimulus, and exhibits chaotic behavior under AC stimulus, which is consistent with the results of real neurons. Furthermore, the image and video processing mechanisms of the CCNN model are analyzed. Experimental results on image segmentation indicate that the CCNN model has better performance than the state-of-the-art of visual cortex neural network models.

description: This work presents a practice-based design and research approach that was used to explore individual, contextual, and institutional requirements, conceptualize and design AR-based Outdoor-scenarios for individual and joint activities in outdoor sports. Based on the need for social interaction and computer-supported collaborative sports and the decreasing physical activity across all ages, game scenarios for the context of outdoor sports were formulated and implemented with a head-worn multimodal AR interface. Members from seven different sports associations were interviewed and design workshops conducted to understand how to design AR-applications to promote an active lifestyle. The prototype and approach presented here will serve to discuss and reflect our future research activities, methodological concepts, and experiences in the field of HCI, CSCS, CSCW, and Design Communities.
title: Cultural Design Compass: Who Do You Design For?

description: The cultural background of our users and its impact on using technology as well as the cultural background of the developers and its infuence on design decisions, is often not considered in research. This paper demonstrates how to self-assess previously derived design recommendations regarding cultural preferences and how to discover potential for improvement. Therefore, 52 design recommendations for large public displays were assigned to cultural dimensions of Hofstede. They were derived by our research group within the last 4 years. As a result, a cultural design compass was developed, visualizing the distribution of design recommendations across the cultural dimensions and indicating areas of focus (e.g. high uncertainty avoidance). The distribution of design recommendations among the cultural dimensions almost completely coincide with Hofstede’s cultural dimension indices for the German culture, showing that there is a high chance to subconsciously derive design recommendations based on our own cultural imprint. In addition, the compass can be used to incorporate cultural indices of other user groups and nationalities to identify design aspects that need improvement. Consequently, without having in mind that cultural preferences and differences exist, the design may not ft u sers w ith d ifferent c ultural b ackgrounds. T he c ultural d esign c ompass s hould support future research within human-computer- interaction to design more precisely for a particular user group, to better classify design recommendations, and to verify whether they match the required users’ cultural preferences.

description: Living cells are known to generate non-Gaussian active fluctuations significantly larger than thermal fluctuations owing to various active processes. Understanding the effect of these active fluctuations on various physicochemical processes, such as the transport of molecular motors, is a fundamental problem in nonequilibrium physics. Therefore, we experimentally and numerically study an active Brownian ratchet comprising a colloidal particle in an optically generated asymmetric periodic potential driven by non-Gaussian noise having finite-amplitude active bursts, each arriving at random and decaying exponentially. We find that the particle velocity is maximum for relatively sparse bursts with finite correlation time and non-Gaussian distribution. These occasional kicks, which produce Brownian yet non-Gaussian diffusion, are more efficient for transport and diffusion enhancement of the particle than the incessant kicks of active Ornstein-Uhlenbeck noise.

description: Augmented Reality (AR) is a powerful tool for supporting remote scenarios. Despite the broad adoption of Hand-Held Devices (HHDs), one common assumption is that Head-Mounted Displays (HMDs) may revolutionize such activities, since collaborators can visualize situated instructions given by remote experts, while in a ’hands-free’ setting. This claim is typically based on toy problem user studies with rather low complexity (Lego Blocks/Tangram puzzles), but what works best for real-life scenarios is not clear. This shows a need for understanding the use/adoption of such devices in real scenarios. In this work, motivated by a partnership with the Industry sector, we discuss how HMDs and HHDs are viewed by different audiences (user study participants, domain experts and target users) for supporting on-site workers during remote maintenance tasks. After all, most stakeholders defend HHDs are still the way to go to address real-life scenarios.

description: We consider a tower of generalized rook monoid algebras over the field $\mathbb{C}$ of complex numbers and observe that the Bratteli diagram associated to this tower is a simple graph. We construct simple modules and describe Jucys-Murphy elements for generalized rook monoid algebras. Over an algebraically closed field $\Bbbk$ of positive characteristic $p$, utilizing Jucys-Murphy elements of rook monoid algebras, for $0\leq i\leq p-1$ we define the corresponding $i$-restriction and $i$-induction functors along with two extra functors. On the direct sum $\mathcal{G}_{\mathbb{C}}$ of the Grothendieck groups of module categories over rook monoid algebras over $\Bbbk$, these functors induce an action of the tensor product of the universal enveloping algebra $U(\hat{\mathfrak{sl}}_p(\mathbb{C}))$ and the monoid algebra $\mathbb{C}[\mathcal{B}]$ of the bicyclic monoid $\mathcal{B}$. Furthermore, we prove that $\mathcal{G}_{\mathbb{C}}$ is isomorphic to the tensor product of the basic representation of $U(\hat{\mathfrak{sl}}_{p}(\mathbb{C}))$ and the unique infinite-dimensional simple module over $\mathbb{C}[\mathcal{B}]$, and also exhibit that $\mathcal{G}_{\mathbb{C}}$ is a bialgebra. Under some natural restrictions on the characteristic of $\Bbbk$, we outline the corresponding result for generalized rook monoids.

description: This paper describes a Participatory design case study on how the reuse of context. While many Third Sector Organisations collect data about their own services and existing data can local communities’ needs, this data is rarely reused by the organisation or shared with others, due to a lack of resources and funding. To explore this issue, we have engaged in Participatory Design research with six locally based social organisations from Scotland. As an outcome of this research, the organisations have imagined the concept of the “Datashare” platform. This is a platform that would allow reusing and sharing of their data by exchanging it widely through the sector and beyond. The paper contributes to knowledge by bringing reflections on the role of the PD process in fostering open data culture for collaboration for Third Sector Organisations highlighting the potential impact of the designed solution.

description: We propose a new theory of second-order viscous relativistic hydrodynamics which does not impose any frame conditions on the choice of the hydrodynamic variables. It differs from Mueller-Israel-Stewart theory by including additional transient degrees of freedom, and its first-order truncation reduces to Bemfica-Disconzi-Noronha-Kovtun theory. Conditions for causality and stability are explicitly given in the conformal regime. As an illustrative example, we consider Bjorken flow solutions to our equations and identify variables which make a hydrodynamic attractor manifest.

description: Organized information campaigns on social media platforms have influence on collective opinions through processes such as social influence and majority opinion formation. Evaluating the effect of such campaigns has become a critical question. We proposed a method by first characterize user engagement and the semantics in public discussions with social media data, then apply a causal impact analysis to measure the effect. We conducted a case study to examine the effect of the 16 Days Campaign (a campaign organized by UN Women) through changes in public discussions of the MeToo, which is a related topic the campaign was aimed to impact. Results showed there were significantly more discussions in MeToo after the launch of the campaign. Hashtags on 16Days topics were used more and by more people. The proposed methods evaluate the direct and indirect diffusion effect of a campaign by quantifying the difference had the campaign not taken place based on social media data. The method enables to evaluate the overall outcome of collaborative work in a social media campaign.

description: We present a calculation of the heavy quark momentum diffusion coefficients in a quark-gluon plasma under the presence of a strong external magnetic field, within the Lowest Landau Level (LLL) approximation. In particular, we apply the Hard Thermal Loop (HTL) technique for the resummed effective gluon propagator, generalized for a hot and magnetized medium. Using the derived effective HTL gluon propagator and the LLL quark propagator we analytically derive the full results for the longitudinal and transverse momentum diffusion coefficients as well as the energy losses for charm and bottom quarks beyond the static limit. We also show numerical results for these coefficients in two special cases where the heavy quark is moving either parallel or perpendicular to the external magnetic field.

description: In this paper, we reflect on the experiences from two Grounded Design (GD) research projects conducted by a multidisciplinary group of researchers between 2019 – 2021 and highlight the methodological foundations and related obstacles for iterative designing. Both projects investigate the phenomena of knowledge sharing and crisis-related learning in business organizations under the GD paradigm, which has been increasingly adopted within the Computer- supported Cooperative Work (CSCW) community. During these projects, the researchers with backgrounds in computer science, business informatics, software engineering, and sociology experienced the need for systematization to transition between the stages of GD. Looking back, we realize that our teams arrived at this systematization by blending the prior knowledge from team members’ original educational backgrounds. While blending practices most likely happens intuitively in interdisciplinary projects, as is often the case of the user-centered design initiatives seen in CSCW and Human-Computer Interaction, little can be found on how this usually happens and its implications. In this paper, we respond to this literature gap by discussing how this blending can facilitate the realization of GD projects and lead to a praxeological information science research perspective, which has ‘methods appropriation’ as key to systematizing abstraction, broader traceability, and flexibility of research methods.

description: The HCI field has seen a growing body of qualitative research, making use of a wide range of activities and methods. Interviews and workshops are some of the main techniques used to help understand user needs and to conduct co-design activities with them. However, these methods might be conducted in various ways and have different advantage and disadvantages. An important aspect influencing the types of activities and methods used is the culture of research participants. This paper aims to compare the research methods conducted in the context of the Saudi Arabian culture. It provides a reflection on the methods used to understand user needs when designing social commerce platforms, including interviews, co-design workshops and critique design workshops. We found that each method has its positives and negatives in terms of user preferences, and can help to obtain useful information at different levels of detail. For example, conducting semi-structured interviews by text was preferred by participants who are at home with their families. However, they can be slower than other methods.

description: Regions and their innovation ecosystems have increasingly become of interest to CSCW research as the context in which work, research and design takes place. Our study adds to this growing discourse, by providing preliminary data and reflections from an ongoing attempt to intervene and support a regional innovation ecosystem. We report on the benefits and shortcomings of a practice-oriented approach in such regional projects and highlight the importance of relations and the notion of spillover. Lastly, we discuss methodological and pragmatic hurdles that CSCW research needs to overcome in order to support regional innovation ecosystems successfully.

description: Family Solemyidae Gray, 1840
Remarks. Scarlato & Starobogatov (1979) introduced the family Acharacidae based on the type genus Acharax Dall, 1908, but most authors consider this synonymous with the more familiar family Solemyidae Gray, 1840. Acharacidae was recognized by Amler (1999) in his bivalve classification, but it was moved to the level of subfamily Acharacinae Scarlato & Starobogatov, 1979, by Bieler et al. (2010). The latest comprehensive synoptical bivalve classification by Carter et al. (2011), followed here, does not recognize Acharacidae, so we place our specimens in the Solemyidae.
Among reports of fossil seep solemyids, Acharax is reported extensively from Japan and southwestern and northwestern USA, with nine species so far having been identified: A. cretacea Kanie & Nishida, 2000 from northern Japan (Amano et al. 2007; Jenkins et al. 2007a; Kiel et al. 2008a); A. dalli (Clark, 1925) from northwestern USA (e.g. Goedert et al. 2003; Campbell & Bottjer 1993); A. gigas (Kanno, 1960) from central Japan (Kanie et al. 1999; Kurihara 2000; Majima et al. 2005); A. johnsoni (Dall, 1891) from central Japan (Nobuhara 2003); A. mikasaensis Kiel, Amano & Jenkins, 2008a from northern Japan (Kiel et al. 2008a); A. stantoni (Vokes, 1955) from south-western USA (Kaim et al. 2014); A. tokunagai (Yokoyama, 1925) from central Japan (Shibasaki & Majima 1997); A. ventricosa (Conrad, 1849) from north-western USA (Campbell & Nesbitt 2004; Nesbitt & Campbell 2004a, b; Campbell et al. 2006); and A. yokosukensis Kanie & Kuramochi, 1995 from central Japan (e.g. Amano & Kanno 1991; Kanie et al. 1992; Kanie 1996; Kanie & Sakai 1997; Amano 2003).
The only other solemyid genus to which seep fossil bivalves have been confidently assigned is Solemya Lamarck, 1818, and these reports are less numerous. They include S. lomitensis Olsson, 1931 from Peru (Olsson 1931), S. sulcifera Cooke, 1919 from Cuba (Kiel & Peckmann 2007), S. cf. angusticaudata Nagao, 1932, from Japan (Kanie et al. 1993) and S. (Petrasma) cf. woodwardiana Leckenby, 1859, from Svalbard (Hryniewicz et al. 2014). Hryniewicz et al. (2016) report older Devonian aged solemyids from Morocco as Dystactella? eisenmanni sp. nov. The only solemyids previously found in the New Zealand fossil record are Solemya from the Cretaceous (Spencer et al. 2009), but Acharax clarificata Dell, 1995, has been reported from modern New Zealand seep environments of the east coast of North Island (Baco et al. 2010; Campbell et al. 2010).

description: The digital twin is a key technology of Industry 4.0. It offers a digital replica of a physical system. As part of research work with SNCF Réseau, we have sought to explore the role the digital twin can play to support coordination mechanisms. We conducted a multi- sited ethnography, which allowed us to define a technology probe to explore our research question in-situ. This exploratory work shows that the digital twin enables the rapid design of computational coordination mechanisms. Furthermore, we raise the point that a digital twin can bind descriptive information about the physical system and information used in coordination practices to move towards effortless coordination.

description: Multi-access edge computing (MEC) emerges as an essential part of the upcoming Fifth Generation (5G) and future beyond-5G mobile communication systems. It adds computational power towards the edge of cellular networks, much closer to energy-constrained user devices, and therewith allows the users to offload tasks to the edge computing nodes for low-latency applications with very-limited battery consumption. However, due to the high dynamics of user demand and server load, task congestion may occur at the edge nodes resulting in long queuing delay. Such delays can significantly degrade the quality of experience (QoE) of some latency-sensitive applications, raise the risk of service outage, and cannot be efficiently resolved by conventional queue management solutions. In this article, we study a latency-outage critical scenario, where users intend to limit the risk of latency outage. We propose an impatience-based queuing strategy for such users to intelligently choose between MEC offloading and local computation, allowing them to rationally renege from the task queue. The proposed approach is demonstrated by numerical simulations to be efficient for generic service model, when a perfect queue status information is available. For the practical case where the users obtain only imperfect queue status information, we design an optimal online learning strategy to enable its application in Poisson service scenarios.

title: I think "Hedging" could be a Feminist Issue in Software Engineering

description: When it comes to software engineering and the development life-cycle, there are a number of opportunities for under-represented groups, gender being the focus of this paper, for decisions to be affected by language. Considering existing linguistics research surrounding gendered language, specifically "Hedging", alongside various stages of the development life-cycle, this paper poses that "Hedging" should be seen as a feminist issue in software engineering, and presents five areas for further research to uncover the potential negative effects it is having, and what can be done to mitigate these. This paper focuses on the subtleties in conversation, and how conversation takes place, building on Feminist Conversation Analysis, Feminist Methodologies, and Software Engineering Methodologies.

description: Solemyidae gen. indet.
(Fig. 3 B)
Material. Three specimens from Moonlight North (Y16/f0694), two medium sized, L4647, L4648, one larger, L4649 (Fig. 3 B), UOA.
Description. Shell small (H up to ca. 12 mm, L up to ca. 21 mm), inequilateral, elongate oval; faint radial striae in anteroventral area, absent in other areas; posterior margin narrowly rounded; anterior margin more broadly rounded; dorsal and ventral margins gently convex; umbones prominent, angulated, situated ca. 20% along shell length from anterior margin; anterior portion of pallial line subparallel to ventral margin, adjoining anterior adductor scar directly medioventrally; anterior adductor scar rather large, situated with centre just in dorsal half of shell close to anterior margin.
Remarks. New Zealand Miocene seep solemyids are known from only three poorly preserved internal moulds. A tenuous pallial line and anterior adductor scar were observed faintly in one of the three specimens. Critically, the posterodorsal region is never well enough preserved to show the presence or absence of an external ligament. Therefore, from the appearance of the shells and quality of preservation it is not possible to categorically place the specimens within any particular solemyid genus. Not only does the preservation of the New Zealand seep specimens hinder identification, but solemyid taxonomy is complex (e.g. Taylor et al. 2008; Kamenev 2009; Oliver et al. 2011) and external shell morphology in this group is conservative (e.g. Taviani et al. 2011; Hryniewicz et al. 2014). The Moonlight North locality is inferred as a bathyal deposit (Saether et al. 2010), and of those solemyid genera found in the New Zealand fossil record and at modern New Zealand seeps, Acharax is a deep-water genus. Solemya is found predominantly in shallower waters of the continental shelf and upper slope (Neulinger et al. 2006; Oliver et al. 2011), although Solemya has been recorded from bathyal depths (Kamenev 2009; Rodrigues et al. 2011; Sato et al. 2013).

description: Collaboration and communication technologies are essential for the support of cooperative work in organisations. Unlike the situation with ERP Systems, there is no single integrated Enterprise Collaboration System that provides systematic and compre- hensive support for all the different forms of collaborative activities. As a consequence, organisations must combine multiple tools, applications and systems to build their Enter- prise Collaboration Platform. In this paper, we present the findings of a focused empirical study that examines the complex collaborative technology landscape in user organisa- tions in order to characterise and understand the evolving portfolios of collaboration soft- ware that have been implemented. Based on a literature review combined with an analy- sis of existing commercial software products, we developed a classification scheme for Areas of Collaborative Work (ArCoW), which is then used to structure an online ques- tionnaire. The analysis of data from 23 responding user companies revealed three typical “configurations” of Enterprise Collaboration Platforms: concentration, where the platform is highly focused on a core ECS/suite with only a few additional collaboration software tools, diversity that also builds around a core ECS/suite but extends this with a wide range of additional tools and dual core characterised by two ECS/Suites with few addi- tions.
