Contract Aware Components, 10 years after
The notion of contract aware components has been published roughly ten years
ago and is now becoming mainstream in several fields where the usage of
software components is seen as critical. The goal of this paper is to survey
domains such as Embedded Systems or Service Oriented Architecture where the
notion of contract aware components has been influential. For each of these
domains we briefly describe what has been done with this idea and we discuss
the remaining challenges.Comment: In Proceedings WCSI 2010, arXiv:1010.233
Internet banking acceptance model: Cross-market examination
This article proposes a revised technology acceptance model to measure consumersâ
acceptance of Internet banking, the Internet Banking Acceptance Model (IBAM). Data
was collected from 618 university students in the United Kingdom and Saudi Arabia. The
results suggest the importance of attitude, such that attitude and behavioral intentions
emerge as a single factor, denoted as âattitudinal intentionsâ (AI). Structural equation
modeling confirms the fit of the model, in which perceived usefulness and trust fully
mediate the impact of subjective norms and perceived manageability on AI. The
invariance analysis demonstrates the psychometric equivalence of the IBAM
measurements between the two country groups. At the structural level, the influence of
trust and system usefulness on AI vary between the two countries, emphasizing the
potential role of cultures in IS adoption. The IBAM is robust and parsimonious,
explaining over 80% of AI
Digital Food Marketing to Children and Adolescents: Problematic Practices and Policy Interventions
Examines trends in digital marketing to youth that uses "immersive" techniques, social media, behavioral profiling, location targeting and mobile marketing, and neuroscience methods. Recommends principles for regulating inappropriate advertising to youth
Affective interactions between expressive characters
When people meet in virtual worlds they are represented by computer animated characters that lack a variety of expression and can seem stiff and robotic. By comparison human bodies are highly expressive; a casual observation of a group of people mil reveals a large diversity of behavior, different postures, gestures and complex patterns of eye gaze. In order to make computer mediated communication between people more like real face-to-face communication, it is necessary to add an affective dimension. This paper presents Demeanour, an affective semi-autonomous system for the generation of realistic body language in avatars. Users control their avatars that in turn interact autonomously with other avatars to produce expressive behaviour. This allows people to have affectively rich interactions via their avatars
Towards a Holistic Approach to Designing Theory-based Mobile Health Interventions
Increasing evidence has shown that theory-based health behavior change
interventions are more effective than non-theory-based ones. However, only a
few segments of relevant studies were theory-based, especially the studies
conducted by non-psychology researchers. On the other hand, many mobile health
interventions, even those based on the behavioral theories, may still fail in
the absence of a user-centered design process. The gap between behavioral
theories and user-centered design increases the difficulty of designing and
implementing mobile health interventions. To bridge this gap, we propose a
holistic approach to designing theory-based mobile health interventions built
on the existing theories and frameworks of three categories: (1) behavioral
theories (e.g., the Social Cognitive Theory, the Theory of Planned Behavior,
and the Health Action Process Approach), (2) the technological models and
frameworks (e.g., the Behavior Change Techniques, the Persuasive System Design
and Behavior Change Support System, and the Just-in-Time Adaptive
Interventions), and (3) the user-centered systematic approaches (e.g., the
CeHRes Roadmap, the Wendel's Approach, and the IDEAS Model). This holistic
approach provides researchers a lens to see the whole picture for developing
mobile health interventions
