Abstract: Spherical silica (SiO2), zinc sulfide (ZnS), and core-shell particles of these materials undergo substantial anisotropic plastic deformation under high-energy ion irradiation. In idual particles can be turned into oblate or prolate ellipsoids with exact control over the aspect ratio. In this letter, we report on the fabrication and optical characterization of thin three-dimensional photonic crystals of spherical particles, which have been anisotropically deformed into spheroidal oblates by means of ion irradiation. As a result of the collective deformation process, both the unit cell symmetry and the particle form factor have been changed leading to appreciable tunability in the optical properties of the photonic crystal.

Abstract: The emergence of autonomous vehicles (AV) heralds new methods of alcohol delivery that are likely to have substantial implications for home drinking. The aim of this study was to explore the factors that have the potential to hasten or restrict widescale increases in alcohol availability resulting from AVs. Thirty-six interviews were conducted with 44 stakeholders across erse sectors. Interviewees discussed their perceptions of how AVs will evolve and the implications for alcohol access. The interview transcripts were analysed to develop a typology of factors that need to be addressed to minimise harms associated with greater home alcohol consumption due to AVs. The interviewees identified a range of demand-side (e.g., enhanced convenience for consumers) and supply-side (e.g., increased efficiency for providers) factors associated with AV home deliveries that could increase the prevalence and volume of home drinking. A third category of factors related to potential forms of regulation: suggested harm-minimisation options related to appropriate enhancements of licensing restrictions and responsible service requirements and the use of various fiscal levers to introduce price barriers. The suggested strategies will require collaborative efforts across government and non-government organisations to address the potential issues arising from the advent of AV alcohol deliveries. Technological and policy solutions will be needed to ensure responsible service of alcohol. This study provides policy makers with insights into forms of intervention that may be required to minimise the harms associated with the use of AVs in alcohol home delivery systems.

Abstract: (1) Background: The automation of transport systems is well underway however, it is unclear how this will affect people’s mobility choices. Changes in these choices have implications for health and the sustainability and efficiency of transport systems, making it important to understand how the advent of autonomous vehicles might affect people’s transport behaviors. The aim of the present study was to address this knowledge gap in the Australian context. (2) Methods: Respondents reported their demographic information, current transport behaviors, the perceived importance of transport-related factors, and attitudes toward autonomous vehicles. They then read a vignette describing a future scenario involving autonomous vehicles that was informed by expert stakeholders. After reading the vignette, the respondents selected those transport options that they would anticipate using in the depicted scenario. Descriptive analyses were conducted to examine changes in transport choices, while regression models were employed to identify the predictors of choices in the future scenario. (3) Results: Most respondents envisaged making greater use of active, shared, and public transport options in an autonomous future, compared to their current use of these options. The intended use of private transport options halved. The most consistent predictor for selecting a certain mode of transport was the current use of that option or its non-autonomous equivalent. (4) Conclusion: Overall, favorable changes in the envisaged use of transport were observed for the hypothetical scenario, which was characterized by improved public transport, a practical active transport infrastructure, and relatively cheap shared autonomous vehicles. If policymakers can act to realize these outcomes, the autonomation of transport is likely to lead to positive societal change.

Abstract: (1) Background: The emergence of autonomous vehicles (AVs) is likely to have substantial implications for walking behaviours due to the availability of new transport options and altered physical environments within cities. The aim of this exploratory study was to identify AV-related factors that could affect walking at the population level and strategies to ameliorate any negative effects. (2) Methods: A total of 46 Australian expert stakeholders were interviewed about their perceptions of the potential impacts of AVs on walking behaviours. The interviewees represented government departments (state and federal), non-government organisations (NGOs), private sector companies, peak bodies, and academia. (3) Results: Interviewees expected AVs to have different effects on in iduals’ ability and motivation to engage in planned versus incidental walking. While those with innate motivation to walk as a form of exercise or leisure may experience enhanced participation opportunities, it appears that incidental walking could be adversely impacted through the availability of convenient AV door-to-door transport options and automated home delivery services that reduce walking related to commuting and shopping. (4) Conclusions: Proactive policy actions are needed to optimize the potential positive impacts of AVs on walking and circumvent the potential negative impacts on valuable incidental walking that constitutes a key component of many people’s total physical activity.
