The research presented examines how pervasive technology can support intra-family communication, supporting existing practices and complimenting them by addressing communication needs currently unmet by current communication media like mobile phones, social networking systems, and so forth. Specifically the investigation focused on busy families, understood here to be families with two working parents and at least one child sharing the same roof. The class of technologies the authors consider are awareness systems, defined as communication systems that support individuals to maintain, with low effort, a peripheral awareness of each other's activities and whereabouts. This research combined a variety of research methods including interviews, web surveys, experience sampling, and field testing of functional prototypes of mobile awareness systems. It also involved the development of several applications, which were either seen as research tools in support of the methods applied or as prototypes of awareness systems that embody some of the envisioned characteristics of this emerging class of technologies. The contribution of this research is along two main dimensions. First in identifying intra-family communication needs that drive the adoption of awareness systems and second in providing directions for the design of such systems.

Does pervasive technology have a role to play in supporting the communication of busy couples? Especially when they are already living together and already have a high degree of awareness of each other's rhythms of daily life, their whereabouts and needs? A two week long field study of an awareness system allowed eight working couples to automatically exchange place, activity and calendar information as well as messages and photos. Data analysis provides both qualitative and quantitative evidence which suggest strongly that such a system can provide support for availability, coordination, reassurance and affection for this group. Findings which inform the design of such systems are: the need for transitions in places instead of location information to support coordination, the two tracks of daily communication of busy parents (reassurance and emergency) and usability barriers in current mobile applications which prevent this group from engaging in photo sharing. The contexts and unexpected uses that participants found in the system are described in detail.

Designers are not always aware of all social consequences of technology, despite practicing usercentred research. With the introduction of disruptive technologies intended and unintended social impacts can be expected, therefore they need to be anticipated. But in general design practices social impacts are completely overlooked. An awareness of the need to anticipate social impacts will not develop automatically. For this purpose a model of awareness has been developed. The model has been evaluated by 12 students. It appeared that the students were able to use the working model, but it turned out to be difficult to imagine changing social practices. It was therefore concluded that students need to increase understanding of the complexity of social practices.

Educators in professional higher education experience difficulties addressing students’ self-awareness in their courses. The topic is often dismissed by students as ‘vague’ or ‘irrelevant’. This is detrimental for learning since knowing who you are and who you want to be is crucial: it guides behaviour and helps to feel balanced and in control. Support is needed to trigger students’ self-awareness and to make this process less demanding. In this paper we present guidelines for interactive triggers supporting students in developing their self-awareness. We asked students to discuss self-made photos in small groups and offered them three paper prototypes of triggers to work with. Questionnaire results and analysis of students’ discussions resulted in insights on how these triggers provoke distinct interaction and support self-awareness. Insights in advantages and disadvantages of the triggers can be used to design and implement innovative interactive systems that engage students in the process of developing self-awareness.

Learning teams in higher education executing a collaborative assignment are not always effective. To remedy this, there is a need to determine and understand the variables that influence team effectiveness. This study aimed at developing a conceptual framework, based on research in various contexts on team effectiveness and specifically team and task awareness. Core aspects of the framework were tested to establish its value for future experiments on influencing team effectiveness. Results confirmed the importance of shared mental models, and to some extent mutual performance monitoring for learning teams to become effective, but also of interpersonal trust as being conditional for building adequate shared mental models. Apart from the importance of team and task awareness for team effectiveness it showed that learning teams in higher education tend to be pragmatic by focusing primarily on task aspects of performance and not team aspects. Further steps have to be taken to validate this conceptual framework on team effectiveness.

This paper describes a project to explore the possibilities of virtual worlds in educating Green IT. In the project a virtual world has been created with various assignments which are meant to create awareness on sustainability aspects of IT. The world (and the assignments) will be incorporated in a course for first-year IT students. In order to measure the effects of the course, a questionnaire has been developed which can be used before and after the course to measure the attitude towards green IT.

Behaviour Change Support Systems (BCSS), already running for the 10th time at Persuasive Technology, is a workshop that builds around the concept of systems that are specifically designed to help and support behaviour change in individuals or groups. The highly multi-disciplinary nature of designing and implementing behaviour change strategies and systems for the strategies has been in the forefront of this workshop from the very beginning. The persuasive technology field is becoming a linking pin connecting natural and social sciences, requiring a holistic view on persuasive technologies, as well as multi-disciplinary approach for design, implementation, and evaluation. So far, the capacities of technologies to change behaviours and to continuously monitor the progress and effects of interventions are not being used to its full potential. The use of technologies as persuaders may shed a new light on the interaction process of persuasion, influencing attitudes and behaviours. Yet, although human- computer interaction is social in nature and people often do see computers as social actors, it is still unknown how these interactions re-shape attitude, beliefs, and emotions, or how they change behaviour, and what the drawbacks are for persuasion via technologies. Humans re-shape technology, changing their goals during usage. This means that persuasion is not a static ad hoc event but an ongoing process. Technology has the capacity to create smart (virtual) persuasive environments that provide simultaneously multimodal cues and psycho-physiological feedback for personal change by strengthening emotional, social, and physical presence. An array of persuasive applications has been developed over the past decade with an aim to induce desirable behaviour change. Persuasive applications have shown promising results in motivating and supporting people to change or adopt new behaviours and attitudes in various domains such as health and wellbeing, sustainable energy, education, and marketing. This workshop aims at connecting multidisciplinary researchers, practitioners and experts from a variety of scientific domains, such as information sciences, human-computer interaction, industrial design, psychology and medicine. This interactive workshop will act as a forum where experts from multiple disciplines can present their work, and can discuss and debate the pillars for persuasive technology.

Introduction: The contemporary scientific literature indicates that numeracy is a multifaceted concept. The ongoing societal and technological transformations underscore the imperative to re-evaluate the attributes characterizing a numerate individual and the strategic initiatives that policymakers should devise and implement to ensure that individuals are not marginalized from participation in public and private domains due to their lack of numeracy proficiency. Numerous empirical investigations on numeracy consistently affirm its pivotal role in enabling individuals to engage autonomously across diverse contexts within their daily lives. However, numeracy’s fundamental role has often been neglected in our societies. The present study scrutinizes the overarching challenges associated with numeracy, particularly emphasizing the challenges regarding healthcare, finance, and the critical utilization and interpretation of data awareness. Methods: A two-phase research framework was adopted to address this inquiry. A comprehensive literature review was conducted to discern the prevalent challenges regarding numeracy awareness. Subsequently, two illustrative case studies were undertaken in Slovenia and Spain to contrast and deliberate upon the insights derived from the literature review. Qualitative research methods were employed to engage in a nuanced exploration of the gathered data. Results: This empirical analysis deduced guidelines aimed at enhancing awareness and ameliorating some of these challenges. Discussion and Conclusion: We conclude that making visible the awareness that adults already have about numeracy in aspects of their lives, such as finance, health, or the use and critical interpretation of data, can give policymakers and curriculum developers clues to design effective numeracy programs to address the multifaceted challenges confronting contemporary society, both in the immediate and foreseeable future.

Innovations are required in urban infrastructures due to the pressing needs for mitigating climate change and prevent resource depletion. In order to address the slow pace of innovation in urban systems, this paper analyses factors involved in attempts to introduce novel sanitary systems. Today new requirements are important: sanitary systems should have an optimal energy/climate performance, with recovery of resources, and with fewer emissions. Anaerobic digestion has been suggested as an alternative to current aerobic waste water treatment processes. This paper presents an overview of attempts to introduce novel anaerobic sanitation systems for domestic sanitation. The paper identifies main factors that contributed to a premature termination of such attempts. Especially smaller scale anaerobic sanitation systems will probably not be able to compete economically with traditional sewage treatment. However, anaerobic treatment has various advantages for mitigating climate change, removing persistent chemicals, and for the transition to a circular economy. The paper concludes that loss avoidance, both in the sewage system and in the waste water treatment plants, should play a key role in determining experiments that could lead to a transition in sanitation. http://dx.doi.org/10.13044/j.sdewes.d6.0214 LinkedIn: https://www.linkedin.com/in/karel-mulder-163aa96/

PurposeThis study aims to identify variability in aviation operators in order to gain greater understanding of the changes in aviation professional groups. Research has commonly addressed human factors and automation in broad categories according to a group’s function (e.g., pilots, air traffic controllers [ATCOs], engineers). Accordingly, pilots and Air Traffic Controls (ATCOs) have been treated as homogeneous groups with a set of characteristics. Currently, critical themes of human performance in light of systems’ developments place the emphasis on quality training for improved situational awareness (SA), decision-making and cognitive load.Design/methodology/approachAs key solutions centre on the increased understanding and preparedness of operators through quality training, the authors deploy an iterative mixed methodology to reveal generational changes of pilots and ATCOs. In total, 46 participants were included in the qualitative instrument and 70 in the quantitative one. Preceding their triangulation, the qualitative data were analysed using NVivo and the quantitative analysis was aided through descriptive statistics.FindingsThe results show that there is a generational gap between old and new generations of operators. Although positive views on advanced systems are being expressed, concerns about cognitive capabilities in the new systems, training and skills gaps, workload and role implications are presented.Practical implicationsThe practical implications of this study extend to different profiles of operators that collaborate either directly or indirectly and that are critical to aviation safety. Specific implications are targeted on automation complacency, bias and managing information load, and training aspects where quality training can be aided by better understanding the occupational transitions under advanced systems.Originality/valueIn this paper, the authors aimed to understand the changing nature of the operators’ profession within the advanced technological context, and the perceptions and performance-shaping factors of pilots and ATCOs to define the generational changes.
