The extent to which voters and parties agree on policies is an important way through which political scientists have empirically studied political representation. This opinion congruence is most often measured by comparing preferences on a number of policy statements. While the selection of policy statements has not escaped scholarly attention, its impact on the reliability of congruence scores, i.e. the degree to which similar levels of opinion congruence are found when different samples of policy statements are used, has been less investigated. This article looks at which factors of statements samples and voters affect the reliability of congruence measures. It does so by simulating over 5 million opinion congruence scores on the basis of a dataset containing 134 voter and party policy preferences. It finds that both the number of statements and their topic diversity positively affect the reliability of congruence estimates. In addition, the congruence estimates of politically less sophisticated voters are more reliable but only when many left-right policy statements are included in the statement selection. Finally, explorative analyses suggest that increasing topic diversity also increases the validity of congruence measures. [less ▲]

If starting to run is an easy decision, committing to a long-term running routine proves to be a more challenging endeavor for many people. In this pictorial, we unravel the design process of Asynja, an artefact that triggers exercise imagery by using natural scents related to running. Relying on peripheral interaction, this research probe subtly nudges users to go running, thereby supporting them to transform their positive intentions into actions. Exploring sensoriality as a design opportunity for behavior change interventions, we invite the community to expand the design space of exercise-related motivational products and systems. [less ▲]

The psychological needs-driven UX approach is a well-explored area in UX research and a powerful framework for the design of optimal experiences with systems and products. However, the transfer from research to practice is slow and this approach is not yet widely used by practitioners. As card- based methods have been shown to support designers in both the generation of ideas and the evaluation of their designs, we created the UX needs cards as a pragmatic tool able to support a needs-driven UX process. We present the iterative development of the card-set and its associated techniques and report on three use cases, demonstrating the effectiveness of this tool for user research, idea generation and UX evaluation. Our empirical findings suggest that the UX needs cards are a valuable tool able to support design practice, being easily understood by lay users and a source of inspiration for designers. Acting as a tangible translation of a research framework, the UX needs cards promote theory-driven design strategies and provide researchers, designers, and educators with a tool to clearly communicate the framework of psychological needs.

Aware of the consequences of their inactive lifestyles, many people still struggle to integrate enough physical activity into their busy lives. Interventions that nudge to reinforce existing active behavior seem therefore more likely to be effective than those adding an activity to daily routines. To encourage people to increase their physical activity level, we designed Discov, a network of physical waypoints triggering people to lengthen their walks. Placed in a public park, Discov encourages people to explore their surroundings in a fun and challenging way by creating an interactive walking experience. Adopting a Research-through-Design approach, we explore the potential of the design of accessible infrastructures and human-environment interactions to impact public health by nudging citizens into being more physically active. We discuss insights gathered through this process and report on first user tests of this interactive walking experience. [less ▲]

This chapter surveys the nascent experimental research on the interaction between human and algorithmic (bot) traders in experimental markets. We first discuss studies in which algorithmic traders are in the researcher’s hands. Specifically, the researcher assigns computer agents as traders in the market. We then followed it up by discussing studies in which the researcher allows human traders to decide whether to employ algorithms for trading or to trade by themselves. The paper introduces the types and performances of algorithmic traders that interact with human subjects in the laboratory, including zero-intelligent traders, arbitragers, fundamentalists, adaptive algorithms, and manipulators. We find that whether algorithm traders earn more profit than human traders crucially depends on the asset’s fundamental value process and the market environment. The potential impact of interactions with algorithms on the investor’s psychology is also discussed. [less ▲]

We live in a post-truth society, where “objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.” In this context, the core claim of this chapter is that to understand the definition and implications of the post-truth society, it is necessary to analyze the theoretical framework under which the concept of post-truth emerged: post-modernism. Under the theoretical framework of post-modernism, the analysis of the precautionary principle is utterly significant since it can be defined as a “paradigmatic principle” of post-modern law. Indeed, as this chapter will demonstrate, the precautionary principle shares the same features of flexibility (in its double dimension of smooth and adaptable principle) and complexity (as an interdisciplinary principle negotiated by scientific experts and political decision-makers) that belong to post-modern principles.

Attentional biases have been posited as one of the key mechanisms underlying the development and maintenance of chronic pain and co-occurring internalizing mental health symptoms. Despite this theoretical prominence, a comprehensive understanding of the nature of biased attentional processing in chronic pain and its relationship to theorized antecedents and clinical outcomes is lacking, particularly in youth. This study used eye-tracking to assess attentional bias for painful facial expressions and its relationship to theorized antecedents of chronic pain and clinical outcomes. Youth with chronic pain (n = 125) and without chronic pain (n = 52) viewed face images of varying levels of pain expressiveness while their eye gaze was tracked and recorded. At baseline, youth completed questionnaires to assess pain characteristics, theorized antecedents (pain catastrophizing, fear of pain, and anxiety sensitivity), and clinical outcomes (pain intensity, interference, anxiety, depression, and posttraumatic stress). For youth with chronic pain, clinical outcomes were reassessed at 3 months to assess for relationships with attentional bias while controlling for baseline symptoms. In both groups, youth exhibited an attentional bias for painful facial expressions. For youth with chronic pain, attentional bias was not significantly associated with theorized antecedents or clinical outcomes at baseline or 3-month follow-up. These findings call into question the posited relationships between attentional bias and clinical outcomes. Additional studies using more comprehensive and contextual paradigms for the assessment of attentional bias are required to clarify the ways in which such biases may manifest and relate to clinical outcomes.

We present a unified approach to the design of social index numbers. Our starting point is a model that employs an exogenously given partition of the population into subgroups. Three classes of group-dependent measures of deprivation are characterized. The three groups are nested and, beginning with the largest of these, we narrow them down by successively adding two additional axioms. This leads to a parameterized class the members of which are based on the differences between the income (or wealth) levels of an individual and those who are better off. We then proceed to show that our measures are sufficiently general to accommodate a plethora of indices, including measures of inequality and polarization as well as distance-based measures of phenomena such as diversity and fractionalization.

This chapter reports on the design, delivery and evaluation of an online research article writing course for doctoral students. The course format was a response to COVID-19 but was designed to be sustainable through enabling flexible, interactive, personalised and independent learning. Its five major components are independent learning tasks, online workshops, writing output, peer review and consultations. Moodle is used for resources and assignments; WebEx for workshops and consultations. Students independently use the e-coursebook to read the theory and submit tasks based on their own texts and articles in their discipline ahead of a workshop on the topic. Additionally, they periodically submit article drafts and engage in peer review. Consultations with the instructor further personalise learning. Having described the course, the chapter goes on to evaluate its affordances and issues by reporting student feedback and teachers’ experiences. It was found that students greatly appreciated the systematic work on their writing in tasks and workshops. However, workshop preparation was very time-consuming for teachers and students would prefer them to be ‘offline’. Furthermore, multidisciplinary peer reviewing and the need to write throughout the course were positively perceived, although requiring greater flexibility in submission times. Consultations were also rated as extremely useful. We conclude with recommendations regarding online course delivery and a blended adaptation for post-COVID purposes. [less ▲]

It is often said that the entrepreneurs of today are the family businesses of tomorrow. This assertion is supported by findings in a Global Entrepreneurship Monitor (2019-20) Report on ‘Family Entrepreneurship’ which cites that 75% of respondent entrepreneurs across 48 economies indicate that their family was actively involved in either starting or developing a new business . In spite of this, and the fact that it is becoming more popular for family firms to encourage entrepreneurialism within the younger generation, it is often challenging for Next Gens to ‘carve out’ an entrepreneurial identity for themselves. This is even more so the case if the intention is to pursue new ideas that are not central to the core business and which might disturb long-planned succession strategies, or expectations held by senior family members. Making the decision to get on board the entrepreneur(ship) is an important career decision that has huge implications, not only for the Next Gens who are planning this, but also for current members of the family business who might have to adjust their expectations.
