"I am definitely manipulated, even when I am aware of it. It’s ridiculous!" - Dark Patterns from the End-User Perspective

Online services pervasively employ manipulative designs (i.e., dark patterns) to influence users to purchase goods and subscriptions, spend more time on-site, or mindlessly accept the harvesting of their personal data. To protect users from the lure of such designs, we asked: are users aware of the presence of dark patterns? If so, are they able to resist them? By surveying 406 individuals, we found that they are generally aware of the influence that manipulative designs can exert on their online behaviour. However, being aware does not equip users with the ability to oppose such influence. We further find that respondents, especially younger ones, often recognise the "darkness" of certain designs, but remain unsure of the actual harm they may suffer. Finally, we discuss a set of interventions (e.g., bright patterns, design frictions, training games, applications to expedite legal enforcement) in the light of our findings. [less ▲]

“I didn’t know water could be so messy”: Coteaching in elementary teacher education and the production of identity for a new teacher of science

Through the examination of the experiences of a pre-service teacher participating in a field-based science methods course, we make evident the ways in which a combination of collaborative teaching experiences and reflexive dialogues allowed for the evolution and transformation of her identity. This teacher is Johaira Lara, the second author of this paper, and we have engaged in a cowriting approach that has created layers of writings over time, with the focus of providing evidence of her changing perceptions and understandings of teaching and learning science. We describe the ways coteaching and cogenerative dialogues provided the opportunity for Johaira to examine and reconsider her views on science teaching, and mediated the production and transformation of her identity. We offer an evolving analysis of her identity transformation related to specific aspects of the course that were pivotal for her emergence as an elementary teacher of science. [less ▲]

“I Feel More Luxembourgish, but Portuguese Too” Cultural Identities in a Multicultural Society

The present investigation focused on cultural identity and the dealing with the belonging to different cultural frames as a migrant in a highly culturally diverse context by comparing two generations of Portuguese families living in Luxembourg. Quantitative standardized questionnaires complemented by in-depth qualitative interviews with parent-child dyads were used in order to assess possible (dis)similarities between first generation Portuguese immigrant parents and their adult children (i.e. second generation) concerning their cultural identities. Generational differences were found regarding the dealing with several cultural frames, language competences and attachment to both discussed cultures. Adult children were more prone to find themselves in a “compatible” identity orientation, compared to the parental generation. Yet, when focussing specifically on the second generation, qualitative data highlighted some issues regarding the perceived views of others on one’s own cultural belonging and the perception of a certain sense of cultural identity denial from others. Our findings contribute to the existing theoretical literature on cultural identity by elucidating some major differences between immigrant parents and their adult children on how they enact the sense of belonging and the dealing with multiple cultural frames on a daily-life basis.

“I Felt so Old This Morning.” Short-Term Variations in Subjective Age and the Role of Trait Subjective Age: Evidence from the ILSE/EMIL Ecological Momentary Assessment Data

Subjective age, how old people feel compared to their chronological age, is a central indicator of age identity and highly predictive for developmental outcomes. While mostly used as a trait-like concept in previous research, recent studies employing experimental designs and daily assessments suggest that subjective age can vary after experimental manipulations or between days. However, less is known about whether subjective age varies over even shorter time frames such as within moments on a given day, how such short-term variability differs by age and its association with trait subjective age. We examined these questions with data obtained from 123 young–old (Mage = 67.19 years) and 47 old–old adults (Mage = 86.59 years) who reported their momentary subjective age six times a day over 7 consecutive days as they were going about their everyday lives. Participants felt younger on a large majority of occasions, and 25% of the total variability in subjective age could be attributed to within-person variation. Within-person variability in subjective age amounted to an average of about 3 years from one moment to the next and did not differ between age groups. However, those with younger trait subjective ages exhibited larger moment-to-moment variation. Our findings extend the literature on subjective age by showing that how old people feel can vary on a momentary basis and that state and trait components of subjective age are related. Further research should investigate the contextual predictors of variability in subjective age and the links between trait and state concepts and developmental outcomes. [less ▲]

Android applications may leak privacy data carelessly or maliciously. In this work we perform inter-component data-flow analysis to detect privacy leaks between components of Android applications. Unlike all current approaches, our tool, called IccTA, propagates the context between the components, which improves the precision of the analysis. IccTA outperforms all other available tools by reaching a precision of 95.0% and a recall of 82.6% on DroidBench. Our approach detects 147 inter-component based privacy leaks in 14 applications in a set of 3000 real-world applications with a precision of 88.4%. With the help of ApkCombiner, our approach is able to detect inter-app based privacy leaks. [less ▲]
