  text: Customer misbehavior poses a major risk in the sharing economy. For example,
    property damage to shared accommodations imposes burdens on both sharing platforms
    and hosts, especially if misbehaving guests purposefully, not coincidentally conceal,
    or fail to report damages. Such misbehavior might be facilitated by remote listing
    management and the lack of face-to-face interactions between hosts and guests.
    Therefore, this study investigated the effects of host–guest interaction modes
    (face-to-face, online-only) and frequency on guests’ misbehavior concealment intentions.
    Social identification and irritation emerged as bright- and dark side mediators,
    respectively. Guests who interacted face-to-face (vs. online-only) with hosts
    exhibited weaker intentions to conceal their misbehavior due to increased social
    identification. Platforms can elicit social identification by engaging guests
    in virtual communities. However, when face-to-face interactions become excessive,
    guests experience irritation and are more likely to conceal their misbehavior.
    These insights offer practical implications for both peer-to-peer sharing platforms
    and hosts.

  text: CAPTCHAs are challenge-response tests that aim at preventing unwanted machines,
    including bots, from accessing web services while providing easy access for humans.
    Recent advances in artificial-intelligence based attacks show that the level of
    security provided by many state-of-the-art text-based CAPTCHAs is declining. At
    the same time, techniques for distorting and obscuring the text, which are used
    to maintain the level of security, make text-based CAPTCHAs diffcult to solve
    for humans, and thereby further degrade usability. The need for developing alternative
    types of CAPTCHAs which improve both, the current security and usability levels,
    has been emphasized by several researchers. With this study, we contribute to
    research through (1) the development of two new face recognition CAPTCHAs (Farett-Gender
    and Farett-Gender&Age), (2) the security analysis of both procedures, and (3)
    the provision of empirical evidence that one of the suggested CAPTCHAs (Farett-Gender)
    is similar to Google's reCAPTCHA and better than KCAPTCHA concerning effectiveness
    (error rates), superior to both regarding learnability and satisfaction but not
    effciency.

  text: Peripheral visual cues lead to large shifts in psychometric distributions
    of temporal-order judgments. In one view, such shifts are attributed to attention
    speeding up processing of the cued stimulus, so-called prior entry. However, sometimes
    these shifts are so large that it is unlikely that they are caused by attention
    alone. Here we tested the prevalent alternative explanation that the cue is sometimes
    confused with the target on a perceptual level, bolstering the shift of the psychometric
    function. We applied a novel model of cued temporal-order judgments, derived from
    Bundesen’s Theory of Visual Attention.We found that cue–target confusions indeed
    contribute to shifting psychometric functions. However, cue-induced changes in
    the processing rates of the target stimuli play an important role, too. At smaller
    cueing intervals, the cue increased the processing speed of the target. At larger
    intervals, inhibition of return was predominant. Earlier studies of cued TOJs
    were insensitive

  text: For an environment to be perceived as being smart, contextual information
    has to be gathered to adapt the system's behavior and its interface towards the
    user. Being a rich source of context information speech can be acquired unobtrusively
    by microphone arrays and then processed to extract information about the user
    and his environment. In this paper, a system for joint temporal segmentation,
    speaker localization, and identification is presented, which is supported by face
    identification from video data obtained from a steerable camera. Special attention
    is paid to latency aspects and online processing capabilities, as they are important
    for the application under investigation, namely ambient communication. It describes
    the vision of terminal-less, session-less and multi-modal telecommunication with
    remote partners, where the user can move freely within his home while the communication
    follows him. The speaker diarization serves as a context source, which has been
    integrated in a service-oriented middleware architecture and provided to the application
    to select the most appropriate I/O device and to steer the camera towards the
    speaker during ambient communication.

  text: In the present study, we examined whether the detection advantage for negative-face
    targets in crowds of positive-face distractors over positive-face targets in crowds
    of negative faces can be explained by differentially efficient distractor rejection.
    Search Condition A demonstrated more efficient distractor rejection with negative-face
    targets in positive-face crowds than vice versa. Search Condition B showed that
    target identity alone is not sufficient to account for this effect, because there
    was no difference in processing efficiency for positive- and negative-face targets
    within neutral crowds. Search Condition C showed differentially efficient processing
    with neutral-face targets among positive- or negative-face distractors. These
    results were obtained with both a within-participants (Experiment 1) and a between-participants
    (Experiment 2) design. The pattern of results is consistent with the assumption
    that efficient rejection of positive (more homogenous) distractors is an im
