This study investigated the role of Self-Service Technologies (SSTs) in dance-based exercise in order to begin exploring the motivations behind the use (or not) of SSTs by ordinary men and women in this context. The research approach employed interviews to gain insights into participants' use of SSTs and their exercise practices, in order to start establishing ways in which dance can be re/incorporated into people's lives through the design of appropriate SSTs. Findings from this study highlight the significant opportunity to further explore how the properties of music and dance can be integrated into the design of new SSTs. Literature suggests dance could be a beneficial exercise format for many people and self-service technology abounds for exercise but is often not used consistently. Our interviews asked participants about dance-based exercise and SSTs for exercise and showed that there is an opportunity to design SSTs to help people access dance-based exercise. SSTs should help people learn dance, build confidence, and dance alone or with others. SSTs could facilitate movement and increase engagement with physical activity whilst addressing issues around logistics, confidence and dance knowledge and experience.

Objective: This research investigates security screeners’ knowledge and the effect that differences in knowledge have on the performance of problem-solving activities. We argue that the development of problem-solving knowledge enables security screeners to perform effective problem-solving activity, which assists search and decision-making processes. Background: Airport security screening research has investigated the many variables that affect security screeners’ search and decision making during simulated threat-detection tasks. Although search and decision making are essential aspects of security screening, few studies have investigated the problem-solving knowledge and activities that support security screening task performance. Method: Sixteen more-experienced and 24 less-experienced security screeners were observed as they performed x-ray screening in the field at an Australian international airport’s departure security checkpoint. Participants wore eye-tracking glasses and delivered concurrent verbal protocol. Results: When interacting with other security screeners, more-experienced screeners demonstrated situational knowledge more than less-experienced screeners, whereas less-experienced screeners experienced more insufficient knowledge. Lag-sequential analysis using combined data from both screener groups showed that situational knowledge facilitated effective problem-solving activity to support search and decision making. Insufficient knowledge led screeners to seek assistance and defer decision making. Conclusion: This study expands current understandings of airport security screening. It demonstrates that security screeners develop knowledge that is specific to problem solving. This knowledge assists effective problem-solving activity to support search and decision making, and to mitigate uncertainty during the x-ray screening task. Application: Findings can inform future security screening processes, screener training, and technology support tools. Furthermore, findings are potentially transferable to other domains.

damage has been done. The association between a range of skin and eye diseases and exposure to UV light is well established. [1] Despite this knowledge leading to public health education campaigns, the improvement and increased use of broad spectrum sunscreens, sun-related skin cancers continue to be a major health concern. [2,3] Clearly, prevention is better than a cure, and so new innovations are needed to improve people's awareness of their risk when enjoying the sun.Solar UV radiation is typically classified into three classes: UV-A (315-400 nm), UV-B (280-315 nm), and UV-C (100-280 nm). UV-C radiation (and high energy UV-B <300 nm), while being the highest in energy, is of little concern in a sun protection setting on the Earth's surface, as radiation in this spectrum is effectively filtered by the ozone layer (Figure 1). Typically it is the UV-B range that is considered the highest risk for disease, as light in this spectral range can affect direct damage to DNA. [4,5] UV-A is typically regarded as capable of damaging connective tissue and blood vessels in deeper dermal layers and is therefore responsible for ageing, but there is a growing body of evidence for the causal link between UV-A radiation and cancer through indirect damage by reactive oxygen species (ROS). [1,4,5] As such, protection from light across the UV spectrum with broad spectrum sunscreens and UV protective clothing has become increasingly important.Although the link between sun exposure and cancer risk has been established, the role of human behavior in mitigating this risk is critical. [3] Broad spectrum sunscreen is capable of protecting from UV radiation, however, appropriate application is often lacking, and can lead to increased exposure time (and overall dose) in sun-seeking individuals. [7] Conversely, while the deleterious link between UV light and disease is well communicated in the community, there is also a need for UV-B light for the metabolism of the essential vitamin D 3 . [8] Vitamin D deficiency can lead to a range of medical conditions, and so a small, sub-damaging dose of UV exposure is necessary for a healthy life. It is clear there are significant challenges in measuring a person's exposure to UV light, providing an estimation of their level of risk, to enable educated decisions about their sun-seeking behavior.A wide range of laboratory prototypes and commercial wearable UV sensors have been developed that aim to improve sun protection. [9,10] They can be broadly divided into two classes, Despite education campaigns linking sun overexposure and skin cancer, it remains one of the leading preventable cancer diagnoses. Skin cancer risk is correlated with overexposure to UV light in sunlight and can be prevented by avoiding exposure. While sun protection can be achieved using sunscreen and clothing, people must be made aware of their risk to facilitate behavior change. Herein, new rewearable UV sensors which overcome the single-use limitations of other products are presented. These sensors utilize diarylethene photoswitch...
