Exploring Maintainability Assurance Research for Service- and Microservice-Based Systems: Directions and Differences
To ensure sustainable software maintenance and evolution, a diverse set of activities and concepts like metrics, change impact analysis, or antipattern detection can be used. Special maintainability assurance techniques have been proposed for service- and microservice-based systems, but it is difficult to get a comprehensive overview of this publication landscape. We therefore conducted a systematic literature review (SLR) to collect and categorize maintainability assurance approaches for service-oriented architecture (SOA) and microservices. Our search strategy led to the selection of 223 primary studies from 2007 to 2018 which we categorized with a threefold taxonomy: a) architectural (SOA, microservices, both), b) methodical (method or contribution of the study), and c) thematic (maintainability assurance subfield). We discuss the distribution among these categories and present different research directions as well as exemplary studies per thematic category. The primary finding of our SLR is that, while very few approaches have been suggested for microservices so far (24 of 223, ?11%), we identified several thematic categories where existing SOA techniques could be adapted for the maintainability assurance of microservices
Scaling Participation -- What Does the Concept of Managed Communities Offer for Participatory Design?
This paper investigates mechanisms for scaling participation in participatory
design (PD). Specifically, the paper focuses on managed communities, one
strategy of generification work. We first give a brief introduction on the
issue of scaling in PD, followed by exploring the strategy of managed
communities in PD. This exploration is underlined by an ongoing case study in
the healthcare sector, and we propose solutions to observed challenges. The
paper ends with a critical reflection on the possibilities managed communities
offer for PD. Managed communities have much to offer beyond mere generification
work for large-scale information systems, but we need to pay attention to core
PD values that are in danger of being sidelined in the process
An investigation into the perspectives of providers and learners on MOOC accessibility
An effective open eLearning environment should consider the target learner’s abilities, learning goals, where learning takes place, and which specific device(s) the learner uses. MOOC platforms struggle to take these factors into account and typically are not accessible, inhibiting access to environments that are intended to be open to all. A series of research initiatives are described that are intended to benefit MOOC providers in achieving greater accessibility and disabled learners to improve their lifelong learning and re-skilling. In this paper, we first outline the rationale, the research questions, and the methodology. The research approach includes interviews, online surveys and a MOOC accessibility audit; we also include factors such the risk management of the research programme and ethical considerations when conducting research with vulnerable learners. Preliminary results are presented from interviews with providers and experts and from analysis of surveys of learners. Finally, we outline the future research opportunities. This paper is framed within the context of the Doctoral Consortium organised at the TEEM'17 conference
Exploring the Referral and Usage of Science Fiction in HCI Literature
Research on science fiction (sci-fi) in scientific publications has indicated
the usage of sci-fi stories, movies or shows to inspire novel Human-Computer
Interaction (HCI) research. Yet no studies have analysed sci-fi in a top-ranked
computer science conference at present. For that reason, we examine the CHI
main track for the presence and nature of sci-fi referrals in relationship to
HCI research. We search for six sci-fi terms in a dataset of 5812 CHI main
proceedings and code the context of 175 sci-fi referrals in 83 papers indexed
in the CHI main track. In our results, we categorize these papers into five
contemporary HCI research themes wherein sci-fi and HCI interconnect: 1)
Theoretical Design Research; 2) New Interactions; 3) Human-Body Modification or
Extension; 4) Human-Robot Interaction and Artificial Intelligence; and 5)
Visions of Computing and HCI. In conclusion, we discuss results and
implications located in the promising arena of sci-fi and HCI research.Comment: v1: 20 pages, 4 figures, 3 tables, HCI International 2018 accepted

How to make privacy policies both GDPR-compliant and usable
It is important for organisations to ensure that their privacy policies are General Data Protection Regulation (GDPR) compliant, and this has to be done by the May 2018 deadline. However, it is also important for these policies to be designed with the needs of the human recipient in mind. We carried out an investigation to find out how best to achieve this.We commenced by synthesising the GDPR requirements into a checklist-type format. We then derived a list of usability design guidelines for privacy notifications from the research literature. We augmented the recommendations with other findings reported in the research literature, in order to confirm the guidelines. We conclude by providing a usable and GDPR-compliant privacy policy template for the benefit of policy writers
Weaving Lighthouses and Stitching Stories: Blind and Visually Impaired People Designing E-textiles
We describe our experience of working with blind and visually impaired people to create interactive art objects that are personal to them, through a participatory making process using electronic textiles (e-textiles) and hands-on crafting techniques. The research addresses both the practical considerations about how to structure hands-on making workshops in a way which is accessible to participants of varying experience and abilities, and how effective the approach was in enabling participants to tell their own stories and feel in control of the design and making process. The results of our analysis is the offering of insights in how to run e-textile making sessions in such a way for them to be more accessible and inclusive to a wider community of participants
