    Urban policymakers of the 2020s must act within various types of wicked socio-ecological disruptions. Under deep uncertainty and time pressure, they must make decisions which will define the scope of possible actions in the future. Our aim was to develop a research instrument that would enable researchers and practitioners to learn about such policymaking. We designed and ran a half-day simulation exercise, the Policy Operations Room (POR). The participants were the top politicians and a group of senior experts from the City of Helsinki, Finland. The design of the exercise was based on a review of simulation and gaming research literature. The exercise managed to integrate - albeit imperfectly - the utilitarian and emancipatory dimensions in futures studies: it gave the participants the utilitarian possibility to practice decision-making and the emancipatory possibility to critically reflect on decision-making in wicked, science-based scenarios. It also gave the researchers a chance to witness urgent decision-making in action. Issues deserving further attention include the inclusion of social-political complexity in the scenarios and practitioner involvement in the design process of the exercise. All in all, the POR constitutes a unique way of integrating science-based assessment of future path dependencies into science-policy research and interaction.

    Farsighted formulations of coalitional formation, for instance, by Harsanyi and Ray and Vohra, have typically been based on the von Neumann-Morgenstern stable set. These farsighted stable sets use a notion of indirect dominance in which an outcome can be dominated by a chain of coalitional "moves" in which each coalition that is involved in the sequence eventually stands to gain. Dutta and Vohra point out that these solution concepts do not require coalitions to make optimal moves. Hence, these solution concepts can yield unreasonable predictions. Dutta and Vohra restricted coalitions to hold common, history-independent expectations that incorporate optimality regarding the continuation path. This paper extends the Dutta-Vohra analysis by allowing for history-dependent expectations. The paper provides characterization results for two solution concepts that correspond to two versions of optimality. It demonstrates the power of history dependence by establishing nonemptyness results for all finite games as well as transferable utility partition function games. The paper also provides partial comparisons of the solution concepts to other solutions.

    Augmented reality (AR) applications have recently emerged for entertainment and educational purposes and have been proposed to have positive effects on social interaction. In this study, we investigated the impact of a mobile, indoor AR feature on sociability, entertainment, and learning. We conducted a field experiment using a quiz game in a Finnish science center exhibition. We divided participants (N = 372) into an experimental group (AR app users) and two control groups (non-AR app users; pen-and-paper participants), including 28 AR users of follow-up interviews. We used Kruskal-Wallis rank test to compare the experimental groups and the content analysis method to explore AR users' experiences. Although interviewed AR participants recognized the entertainment value and learning opportunities for AR, we did not detect an increase in perceived sociability, social behavior, positive affect, or learning performance when comparing the experimental groups. Instead, AR interviewees experienced a strong conflict between the two different realities. Despite the engaging novelty value of new technology, performance and other improvements do not automatically emerge. We also discuss potential conditional factors. Future research and development of AR and related technologies should note the possible negative effects of dividing attention to both realities.

    The rise of modern socio-digital technologies has fundamentally changed the everyday environments in which young people communicate with each other and cultivate interests. To gain a more sophisticated understanding of this phenomenon, this study provides in-depth, qualitative insights into adolescents’ experiences of their socio-digital developmental ecologies. The 15 interview participants were recruited based on a previously conducted questionnaire. The semi-structured theme interview addressed the socio-digital aspects of the participants’ interest-driven behaviours and related networks with the aid of participant-generated egocentric maps. The data not only qualitatively enrich the picture on adolescents’ friendship- and interest-driven socio-digital participation but also provide new perspectives on the phenomena through the added network-layer of analysis. The youth seem to vary in their motivational profiles related to their participation and the potential relevant psychological background factors for this variation are considered. Educational implications of these results are discussed when it comes to effective student engagement and connected learning.

    In this study we investigate the effects of long-term technology enhanced learning (TEL) in mathematics learning performance and fluency, and how technology enhanced learning can be integrated into regular curriculum. The study was conducted in five second grade classes. Two of the classes formed a treatment group and the remaining three formed a control group. The treatment group used TEL in one mathematics lesson per week for 18 to 24 months. Other lessons were not changed. The difference in learning performance between the groups tested using a post-test; for that, we used a mathematics performance test and a mathematics fluency test. The results showed that the treatment group using TEL got statistically significantly higher learning performance results compared to the control group. The difference in arithmetic fluency was not statistically significant even though there was a small difference in favor of the treatment group. However, the difference in errors made in the fluency test was statistically significant in favor of the treatment group.

    We study pure coordination games where in every outcome, all players have identical payoffs, 'win' or 'lose'. We identify and discuss a range of 'purely rational principles' guiding the reasoning of rational players in such games and compare the classes of coordination games that can be solved by such players with no preplay communication or conventions. We observe that it is highly nontrivial to delineate a boundary between purely rational principles and other decision methods, such as conventions, for solving such coordination games.

    The notion of “deontic rights”—the capacity of an individual to determine action—is described as a tool to analyze human power plays in the turn‐by‐turn unfolding of social interaction. Drawing on various bodies of literature, the paper portrays the organization of the adjacency‐pair sequence as the key locus of negotiation over deontic rights. How such negotiations happen in practice is also considered. Two deontic patterns instantiating themselves in sequential relations—deontic congruence and deontic incongruence—are discussed. Negotiations of deontic rights are suggested to take place specifically in and through three different forms of deontic incongruence, each of which involves a subtle mismatch between the claims of deontic rights of the first speaker and the recipient's treatment of these claims. These implicit power plays easily escape the eye and are therefore difficult to reflect upon and counteract by the participants themselves, which makes a thorough understanding of these mechanisms important.

    In this article, learning is studied in in situ applications that involve sensors. The main questions are how to conceptualize experiential learning involving sensors and what kinds of learning applications using sensors already exist or could be designed. It is claimed that experiential learning, context information and sensor data supports twenty first century learning. The concepts of context, technology-mediated experiences, shared felt experiences and experiential learning theory will be used to describe a framework for sensor-based mobile learning environments. Several scenarios and case examples using sensors and sensor data will be presented, and they will be analyzed using the framework. Finally, the article contributes to the discussion concerning the role of technology-mediated learning experiences and collective sensor data in developing twenty first century learning by characterizing what kinds of skills and competences are supported in learning situations that involve sensors.

    We investigated user experiences from 117 Finnish children aged between 8 and 12 years in a trial of an English language learning programme that used automatic speech recognition (ASR). We used measures that encompassed both affective reactions and questions tapping into the children' sense of pedagogical utility. We also tested their perception of sound quality and compared reactions of game and nongame-based versions of the application. Results showed that children expressed higher affective ratings for the game compared to nongame version of the application. Children also expressed a preference to play with a friend compared to playing alone or playing within a group. They found that assessment of their speech is useful although they did not necessarily enjoy hearing their own voices. The results are discussed in terms of the implications for user interface (UI) design in speech learning applications for children.
