Abstract Background North America is amidst an opioid overdose epidemic. In many settings, particularly Canada, the majority of overdose deaths occur indoors and impact structurally vulnerable people who use drugs alone, making targeted housing-based interventions a priority. Mobile applications have been developed that allow individuals to solicit help to prevent overdose death. We examine the experiences of women residents utilizing an overdose response button technology within a supportive housing environment. Methods In October 2019, we conducted semi-structured qualitative interviews with 14 residents of a women-only supportive housing building in an urban setting where the overdose response button technology was installed. Data was analyzed thematically and framed by theories of structural vulnerability. Results While participants described the utility and disadvantages of the technology for overdose response, most participants, unexpectedly described alternate adoptions of the technology. Participants used the technology for other emergency situations (e.g., gender-based violence), rather than its intended purpose of overdose response. Conclusions Our findings highlight the limitations of current technologies while also demonstrating the clear need for housing-based emergency response interventions that address not just overdose risk but also gender-based violence. These need to be implemented alongside larger strategies to address structural vulnerabilities and provide greater agency to marginalized women who use drugs.

The Way

An inexpensive colour-picture generating system is described and a few applications are indicated. The basic equipment comprises a microprocessor; a colour television monitor with R, G, and B inputs; and a number of video memories. The most important characteristic of the apparatus is the way in which video memories are used in combination with a set of colour registers and very fast digital/analog converters. The equipment permits display of any kind of figure with a maximum of eight colours simultaneously present. Figures may be generated point by point by the experimenter, or by computer. Colours can be changed continuously with the R, G, and B channels each receiving one out of 256 possible values.

Audio Stimulus

The power of visual and audio messages on television commercial (TVC) is critical to create the advertised brand awareness. The use of popular songs as an advertisement attraction is often used in television commercials. This paper is a case study of Mizone TVC in 2012. The popular song should be able to help the visual appeal used in helping audiences remember brands and advertisements. This study aims to determine the role and impact of visual appeal on TVC that use popular song as the appeal of music to brand reminders. The method used in this study is based on marketing approach and advertisement evaluation research through advertising stimulus recall test method. The first stage is an audio stimulus test by playing a popular song from the case study. The second stage is a visual stimulus test by showing some advertising frames as a visual stimulus. The third stage is to show the ads as a whole to know the response about the attractiveness of the ad to brand recall. This method is tested on the respondent which is the target audiences of Mizone. The analysis of the visual stimulus visual recall shows the use of visual appeal not only from TVC talents but also through advertising messages packaged with unique, distinct visual approaches and identity that can help audiences to better remember the brand.

AbstractSensorimotor synchronization (SMS), the rhythmic coordination of perception and action, is a fundamental human skill that supports many behaviors, from daily repetitive routines to the most complex behavioural coordination, including music and dance (Repp 2005; Repp & Su, 2013). Research on SMS has been mostly conducted in the laboratory using finger tapping paradigms, where participants typically tap with their index finger to a rhythmic sequence of auditory stimuli. However, these experiments require equipment with high temporal fidelity to capture the asynchronies between the time of the tap and the corresponding cue event. Thus, SMS is particularly challenging to study with online research, where variability in participants’ hardware and software can introduce uncontrolled latency and jitter into recordings. Here we present REPP (Rhythm ExPeriment Platform), a novel technology for measuring SMS in online experiments that can work efficiently using the built-in microphone and speakers of standard laptop computers. The audio stimulus (e.g., a metronome or a music excerpt) is played through the speakers and the resulting signal is recorded along with participants’ responses in a single channel. The resulting recording is then analyzed using signal processing techniques to extract and align timing cues with high temporal accuracy. This analysis is fully automated and customizable, enabling researchers to monitor online experiments in real time and to implement a wide variety of SMS paradigms. In this paper, we validate REPP through a series of calibration and behavioural experiments. We demonstrate that our technology achieves high temporal accuracy (latency and jitter within 2 ms on average), high test-retest reliability both in the laboratory (r = .87) and online (r = .80), and high concurrent validity (r = .94). We also suggest methods to ensure high data quality in online SMS experiments using REPP while minimizing recruitment costs. REPP can therefore open new avenues for research on SMS that would be nearly impossible in the laboratory, reducing experimental costs while massively increasing the reach, scalability and speed of data collection.

Self Motion

Reaction times (RTs) to purely inertial self-motion stimuli have only infrequently been studied, and comparisons of RTs for translations and rotations, to our knowledge, are nonexistent. We recently proposed a model (Soyka et al., 2011) which describes direction discrimination thresholds for rotational and translational motions based on the dynamics of the vestibular sensory organs (otoliths and semi-circular canals). This model also predicts differences in RTs for different motion profiles (e.g., trapezoidal versus triangular acceleration profiles or varying profile durations). In order to assess these predictions we measured RTs in 20 participants for 8 supra-threshold motion profiles (4 translations, 4 rotations). A two-alternative forced-choice task, discriminating leftward from rightward motions, was used and 30 correct responses per condition were evaluated. The results agree with predictions for RT differences between motion profiles as derived from previously identified model parameters from threshold measurements. To describe absolute RT, a constant is added to the predictions representing both the discrimination process, and the time needed to press the response button. This constant is approximately 160 ms shorter for rotations, thus indicating that additional processing time is required for translational motion. As this additional latency cannot be explained by our model based on the dynamics of the sensory organs, we speculate that it originates at a later stage, e.g., during tilt-translation disambiguation. Varying processing latencies for different self-motion stimuli (either translations or rotations) which our model can account for must be considered when assessing the perceived timing of vestibular stimulation in comparison with other senses (Barnett-Cowan and Harris, 2009; Sanders et al., 2011).
