“…It was likely that the context intervention was not strong enough to improve memorability, even though some previous studies have found a context effect for seemingly weak context interventions (e.g., listening to music (Smith, 1985). A background scene on a computer monitor has been found to provide context effects (Stefanucci et al, 2007). However, in that instance, there was a very large monitor accompanied by ambient noises.…”

Authentication verifies users’ identities to protect against costly attacks. Graphical authentication schemes utilize pictures as passcodes rather than strings of characters, numbers, and symbols. Pictures are more memorable than alphanumeric passwords. Two studies investigated the memorability of graphical passcodes when users need to remember multiple passcodes or longer passcodes. Longer passcodes provide advantages to security by protecting against brute force attacks, and multiple passcodes need to be investigated as users need to authenticate for numerous accounts. It was found that participants have strong item retention for passcodes of up to eight images and for up to eight accounts. Also, these studies examined whether context can facilitate memorability. The impact of context was not found as assumed in the literature. Overall, memorability was still higher for all the number and length passcode conditions compared with alphanumeric passwords. These studies take steps toward understanding the readiness of graphical schemes as an authentication option.

“…The provision of contextualized memory aids should help consultants to overcome their difficulties to integrate additional knowledge from external information sources into the verbal discussions with clients (addressing SO3). Context information can provide consultants with additional memory cues (Stefanucci et al, 2007), thus giving them additional thematic connection points for integrating new knowledge suitably into ongoing discussions.…”

Purpose -The purpose of this paper is to investigate the face-to-face citizen service encounter in public administrations' front offices, and present a novel qualification approach to empower service personnel on-the-job, and thereby deepen the knowledge on the role of information and communication technology for advancing governmental reforms. Design/methodology/approach -The presented study follows a design science research methodology, conducted in collaboration with the public administration of a major German city. Data were collected using multiple quantitative and qualitative methods, including questionnaires, semi-structured interviews and video analysis. Findings -A novel on-the-job qualification approach for empowering public employees in their job-related skills, building on the concept of affordances, is developed. Thereto, six design principles for equipping artifacts with counseling affordances are presented. Evaluations in real-world environments provide first evidence that "learning with counseling affordances" constitutes an effective qualification measure to initiate experiential learning on-the-job, helping employees in the resource-restricted work environment of public front offices to obtain the skills to provide superior advisory services. Research limitations/implications -The "learning with counseling affordances" approach was developed in collaboration with an individual major German city and the paper provides first evidence of its effectiveness and suitability. Hence, the study's insights should be approved by further research to strengthen generalizability. Originality/value -The paper highlights the previously neglected aspects of employee's skills and qualification for promoting governmental transformation. By highlighting the beneficial relationship between affordances and on-the-job learning, the paper provides novel insights on the role of information and communication technology to promote governmental transformation.
