EXPRESS: Leveraging Rational Addiction Theory to Reduce Mobile Usage
Full text linkThe pervasive use of smartphones has raised concerns about their addictive and maladaptive nature. This paper introduces an intervention based on rational addiction theory to cost-effectively nudge consumers to reduce smartphone usage, promoting sustainable digital consumption. We examine whether pre-announcing future targets to reduce smartphone usage influences current consumption and behavioral change. We develop a mathematical model incorporating habit formation, satiation, and projection bias, and test its predictions in three pre-registered randomized control trials using objectively measured smartphone usage. When future incentives and targets are pre-announced, consumers reduce usage pre-emptively compared to their baseline, consistent with rational addiction. This occurs only when participants are given fixed daily reduction targets, not when incentivized proportionally for reductions over time, and seems to reflect forward-looking habit formation, as other explanations (e.g., goal priming or capability testing) were unlikely to drive results. Interestingly, pre-emptive reductions are stronger among heavy users and those with stronger beliefs in meeting their targets. We also find that pre-emptive reductions help consumers meet their targets during the incentivized period and might support post-treatment behavioral sustenance. Our model fitting results reveal considerable heterogeneity and offer insights into how digital detox experiences can be structured to promote sustainable behavior change.yesPublishe

Global sensitivity analysis of uncertain parameters in Bayesian networks
No full textTraditionally, the sensitivity analysis of a Bayesian network studies the impact of individually modifying the entries of its conditional probability tables in a one-at-a-time (OAT) fashion. However, this approach fails to give a comprehensive account of each inputs' relevance, since simultaneous perturbations in two or more parameters often entail higher-order effects that cannot be captured by an OAT analysis. We propose to conduct global variance-based sensitivity analysis instead, whereby n parameters are viewed as uncertain at once and their importance is assessed jointly. Our method works by encoding the uncertainties as n additional variables of the network. To prevent the curse of dimensionality while adding these dimensions, we use low-rank tensor decomposition to break down the new potentials into smaller factors. Last, we apply the method of Sobol to the resulting network to obtain n global sensitivity indices, one for each parameter of interest. Using a benchmark array of both expert-elicited and learned Bayesian networks, we demonstrate that the Sobol indices can significantly differ from the OAT indices, thus revealing the true influence of uncertain parameters and their interactions.yesPublishe
GAME: GrAspable Media Entertainment
Full text linkThis research explores the development of a Tangible User Interface (TUI) designed for gaming purposes. GAME (GrAspable Media Entertainment) is an innovative project that enables users to physically interact with digital gaming elements, bridging the gap between the physical and virtual worlds. This is achieved through the integration of multiple technologies, including a motion capture system (Optitrack), a short-throw projector (Optoma UHD35STx), and an agent-based simulation software (GAMA). GAME supports interactive gameplay (e.g., Player vs. Player, Player vs. AI), offering a more immersive and versatile gaming experience than conventional screen-based implementations. Furthermore, GAME leverages blockchain technology, specifically the Ripple protocol (i.e., XRPL), to facilitate gameplay actions such as store progress checkpoints, secure in-game transactions, and track player scores. The addition of the blockchain component allows easy game customization, and enhances the overall gaming experience. In conclusion, the combination of tangible user interfaces with blockchain technology can pave the way for future developments in important fields such as education, training, and entertainment where novel interaction methods are paramount.yesPublishe
The Question of Principalities in Kyivan Rus’
Full text linkThe present article is the result and, to a certain extent, an example of the challenges posed by the use of digital humanities in the field of medieval studies. Digital humanities, as a new methodology, if properly used, should contribute to the fruitful opening of new avenues for research. Otherwise, it is just solipsistic entertainment.yesPublishe
Environmental sensitivity in the self-assessment of cultural intelligence development
Full text linkPurpose
Cultural intelligence (CQ) is a key ability that enables employees to effectively interact with individuals from different cultures. Research suggests that not all individuals self-assess their CQ learning similarly. This exploratory study aims to identify systematic inter-individual differences in self-assessed CQ development arising from environmental sensitivity, a relevant trait given that research estimates that 20–30% of individuals are highly sensitive.
Design/methodology/approach
This study examines the contribution of an intercultural learning program to CQ development. It draws on survey data collected from all participants in multiple cohorts over 11 years. The participants were highly qualified junior employees representing 25 countries, with 96% from Europe. Data were gathered prior to and following program participation to evaluate changes in self-assessed CQ.
Findings
Results indicate that participants with greater environmental sensitivity reported lower self-assessed CQ development. Team size moderated this relationship: the negative association was significant in dyads, but not in triads or quads. Higher levels of prior international experience did not significantly affect the outcome.
Originality/value
The study contributes to the understanding of CQ development by highlighting the role of environmental sensitivity, an often-overlooked trait, and it critically assesses the validity of the prevailing evaluation of the effectiveness of CQ learning based on self-assessments in both research and practice. The results offer insights for the design of CQ learning programs and underscore the need to consider the unique challenges faced by environmentally sensitive learners in enhancing their CQ.This work was supported by Ministerio de Ciencia, Innovación y Universidades (award-id: This paper was partially funded by PID2023-148086N) and EU-Lifelong Learning Programme (awardid: ERA10-2013-005, IP-2012-005 and IP/2011-09).YesPublishe
Can Politicians Say That? What Shapes Public Responses to Speech Scandals
No full textWhy do some politicians face greater backlash for using insensitive language against identity groups while others do not? Existing explanations focus either on the content of speech or the context in which it occurs. In this article, we propose an integrated framework that considers both and test it using a preregistered conjoint survey on a national U.S. sample. Our findings provide partial support for our expectations. Subjects react most negatively to insensitive speech when the target belongs to their own identity group, when aggravating circumstances exist, and when politicians are of an opposing political party. Our article extends growing scholarship on speech scandals, which has largely explained the fates of politicians as a function of a small number of causative variables in isolation.YesPublishe
Screening Dyslexia Using Visual Auditory Computer Games and Machine Learning
Full text linkReading acquisition is one the main keys for school success and a crucial component for empowering individuals to participate meaningfully in society. Yet, it is still a challenging skill to acquire for around 10% of children that have dyslexia, a type of neuro-developmental disorder that affects the ability to learn how to read and write. Dyslexia is often under-diagnosed, and normally children with dyslexia are only detected once they fail in school, even though dyslexia is not related to general intelligence. In this work, we present an approach for screening dyslexia using language-independent games in combination with machine learning models. To reach this goal, we designed the content of a computer game, collected data from 137 children playing this game (51 with dyslexia) in different languages -German, Spanish and English- and created a prediction model using different machine learning classifiers. Our method provides a precision of 0.78 and recall of 0.79 for German and a precision of 0.83 and recall of 0.80 for all languages when Extra Trees are used, with an accuracy of 0.67 and 0.75, respectively. Our results open the possibility of inexpensive online early screening of dyslexia for young children using non-linguistic elements.YesPublishe
A Meta-Analysis of Attitudes Towards Migrants and Displaced Persons
Full text linkSince the 2010s, social scientists have increasingly conducted survey-experimental studies that explore what factors drive public attitudes towards migrants in host countries. We conducted a systematic meta-analysis of 118 such studies, comprising 428,881 respondents from fifty-three countries. We find that sociotropic economic concerns play a key role, with individuals being more welcoming towards migrants who contribute to the economy through their professional occupation, education, or language skills. In contrast, there is limited evidence that hosts evaluate migrants based on egocentric economic concerns. Cultural concerns are also important; notably, we uncover a persistent anti-Muslim bias. Humanitarian concerns shape attitudes as well – especially towards forcibly displaced migrants, who are generally viewed more favorably than economic migrants. Climate migrants place between conflict migrants and economic migrants in terms of public perception. Our meta-analysis raises several questions that remain unanswered in the literature, suggesting important directions for future research.Peter van der Windt is thankful for funding from the Center of Behavioral Institutional Design and Tamkeen under the NYU Abu Dhabi Research Institute Award CG005.

The influence of self-brand connection on consumer reactions to symbolic incongruency and perceived betrayal
Full text linkThis research provides compelling evidence that consumer reactions toward symbolically incongruent brand behaviors depend on their level of self-brand connection. It challenges the conventional belief that high self-brand connection works as a protecting shield for brands and reveals that consumers with higher (vs. lower) self-brand connection react more negatively toward symbolically incongruent brand behaviors because they feel betrayed by the brand. The results unveil that a sense of betrayal can be incited,when a brand's behavior is symbolically incongruent with its established meaning. This pattern of consumer responses is consistent across four experimental studies,which involved a diverse sample of 563 participants from different countries,including the United States,the United Kingdom,and Spain and used various product categories. The results consistently show that individuals with high self-brand connection display an increased intention to engage in negative word of mouth,along with a decline in their brand attitudes and purchase intentions,driven by feelings of betrayal. This effect is further intensified for consumers with higher self-enhancement need. It is worth noting that prior literature on betrayal has often linked such feelings to more significant transgressions and behaviors with immoral connotations. © 2024 The Authors.
