In this essay, we revisit our interdisciplinary approach to the “becoming-cinema” of Chinese life and cities in the contemporary era, while critically revisiting our notion of “shi-nema” (which combines the Chinese concept of “shi” (势) with a detoured notion of “cinematicity”) which we forward as a provocative “image for thought” that explodes the concerns of modern film studies. Revisiting our multi-scalar fractal method, on this outing we specifically engage with a nexus of new semiocapitalist images and urban sites/sights that foreground how rapidly the psychogeographic circumstances in post-socialist Chinese cine-cities evolve and mutate. Our essay opens with a fresh film-philosophy conceptualisation of “afterimages”, blending cinematic, city and conceptual varieties before moving on to critically engage with a new constellation of interviews and images drawn from Chinese film, television, streaming platforms, social media and commercial real estate apps.

Climate change is predicted to make extreme weather events worse and more frequent in many places around the world. In New Zealand, the Earthquake Commission (EQC) was created to provide insurance for earthquakes. In some circumstances, however, homeowners affected by extreme weather events can also make claims to the EQC – for landslip, storm or flood events. In this paper, we explore the impact of this public natural hazard insurance on recovery from weather-related events. We do this by using a proxy for short-term economic recovery: satellite imagery of average monthly night-time radiance. Linking these night-time light data to precipitation data records, we compare areas which experienced damage from extreme rainfall episodes to those that suffered no damage even though they experienced extreme rainfall. Using data from three recent intense storms, we find that areas that experienced property damage, and were paid in a timely manner by EQC, did not fare any worse than areas that suffered no property damage but were exposed to these extreme precipitation events. This finding suggests that EQC insurance is serving its stated purpose by protecting claimants from the adverse impact of extreme weather events.

In clinical practice, evidence suggests that teaching ethics using normative ethical theory has little influence on the ethical actions of providers in practice. Thus, new training methods are needed that improve clinician response to ethical problems. A sensemaking approach to ethics training has demonstrated promise as an evidence-based pedagogical method to improve ethical reasoning and response. Project ECHO (Extension for Community Health Outcomes) is theoretically linked to improved sensemaking. This study examines the effectiveness of ECHO and training in use of sensemaking approaches to ethical response by clinicians. A quasi-experimental design study using univariate linear regression was used to examine the effect of the three types of ethics training on ethical response self-efficacy scores, while controlling for participant characteristics of years in practice, discipline and sex. We found evidence that training in sensemaking through participation in ECHO promotes improved ethical response self-efficacy of clinicians. However, results also suggest that a traditional ECHO format that does not explicitly introduce sensemaking strategies into the training does not result in the same learning outcomes as measured through an ethical response self-efficacy survey. This study found important preliminary results to support use of sensemaking approaches in clinical ethics training.

Climate change, as well as associated mitigation efforts, will substantially disrupt some economies. Seemingly inevitable market and policy changes will push economies to transition away from reliance on industries with higher carbon emissions and bring transient economic impacts, especially in regions that are currently heavily reliant on such industries. This situation is not unusual in a global context. To underpin better‐informed decisions that enable a smoother economic transition to a low‐emissions future, we developed a ‘latent economic vulnerability to emissions reduction’ (LEVER) index, which maps and explores regions that are more likely to be economically impacted from climate change mitigation. Thus, this paper provides an analysis and discussion of the potential regional implications of a future low‐emissions economy, with the analysis contextualised for the state of Queensland, Australia. Given this case study, the economic impacts and future of coal‐fired power stations, coal mining and renewable energy are discussed. The LEVER index weighs the risk of high carbon economic exposure against the variability in carbon economic resilience from employment in low‐emission sectors across local economies. We find that between 3 and 6 per cent of Queensland regions are assessed as having a very high latent economic vulnerability to increased decarbonisation of industrial activities. To promote a smoother transition, these regions will require targeted investments and strategies to enable their transition towards lower carbon‐intensive systems, while maximising economic and social outcomes.

Prior research has demonstrated that the characteristics of school environments can impact the development of creativity in children. Thus, we explored the construct of creativity in the context of a Montessori environment. We used the Evaluation of Potential Creativity to measure creativity in children during one academic year. The study sample comprised 77 third-grade students at a Montessori public school in the southeastern United States and 71 demographically similar students at a traditional public school. Results show that Montessori students performed somewhat better on the Evaluation of Potential Creativity assessment than similar non-Montessori students did. Subgroup analyses indicate that male Montessori students demonstrated higher creativity than did male non- Montessori students. The findings of this study augment the body of research supporting creative development in Montessori children and suggest that researchers should continue to focus on the measurement of creativity in studies related to the efficacy of the Montessori model.

Various researchers have developed techniques to control delamination in laminated structures. One of these techniques is “interleaving,” adding high toughness material to key interfaces in a laminate. This paper studies using polyester veil as a low-cost interleaf alternative to other materials and focuses on a nonwoven, polyester spunbond material. Two different interleaf thicknesses, 0.18 mm and 0.74 mm, are primarily used. In addition, fine 4 g/m2 polyester was also compared. Carbon/epoxy composites are manufactured using 2 × 2 Twill 24″–12k carbon fibers embedded in an epoxy resin, with polyester interleaves at key interfaces. Specimens are fabricated using wet hand layup and cured at room temperature in a vacuum bag. Mode I fracture toughness is measured using the double cantilever beam test and Mode II fracture toughness is examined using the end-notched flexure test. Further evaluation is made using static indentation and full penetration impact testing. Toughness is compared, and the resulting fracture surfaces are investigated. Significant improvement is seen in Mode I testing. Up to a factor of 4 increase in propagation energy per unit area resulted from the inclusion of the interleaf material. Smaller improvements were observed in Mode II, with the best cases showing an increase in propagation energy to maximum load by about a factor of 2 compared with control cases. The polyester interleaf significantly influences the fracture morphology observed in static indentation and full penetration tests.

A mono-energetic X-ray beam from a portable X-ray fluorescence device was used to excite characteristic X-rays from zinc in a series of nail clipping phantoms. Twenty nail clipping phantoms having equal zinc concentrations of ~40 µg/g, but with different physical characteristics, were measured individually for 300 s using a small diameter (~1 mm) X-ray beam. Energy spectra obtained from the measurements were analyzed using PyMca software. Zinc signal size varied widely between the different clippings, with a relative standard deviation of 41% observed in the combined signal from zinc Kα and Kβ characteristic X-rays. Three different normalization approaches were introduced to account for variation in the amounts of sample interrogated by the X-ray beam. All three approaches produced similar results, and successfully reduced the relative standard deviation to between 12% and 13%. A clear trend was still observed, however, between the normalized zinc signal and the thickness of clipping measured. To account for this effect, normalized signals were adjusted to calculate “thickness-corrected” values. The relative standard deviation of these thickness-corrected values was 6.2%. Reproducibility of measurement from individual clippings was excellent, with relative standard deviations on the order of 1%, with or without normalization. Overall, this new method of measuring zinc in nail shows promise for the assessment of zinc status in humans using a portable device. The method is sensitive, rapid, and requires only a single nail clipping.

Globally, the development of the unconventional natural gas (UNG) industry is expected to continue as gas consumption increases in the transition to cleaner energy sources. However, social and regulatory factors may constrain UNG activity at regional scales. Robust impact assessments of the effects of the UNG industry at different phases of development could help reduce trade-offs of energy policy and promote overall welfare improvements. We assessed if the early phases of the coal seam gas (CSG, a type of UNG) industry in New South Wales, Australia produced regional economic changes between 2001 and 2011. We combined spatial econometrics, genetic matching algorithms and seemingly unrelated regressions with instrumental variables to control for multiple factors influencing regional economic patterns (e.g., climate, human capital) to estimate the effect of the CSG industry on local income and employment. Results show that regions with CSG activity had 7% (±5%, 95% C.I.) higher family income than regions without CSG mining. No statistical evidence of indirect employment multiplier effects from CSG activity were found. The analysis can inform social license and regulatory decisions related to the CSG industry that impact competing social priorities such as energy and water security, economic growth and environmental health.

As if responding to the widespread condemnation of George Lucas's 'CGI-heavy' prequel Star Wars trilogy, J.J Abrams’s 2015 'reboot' The Force Awakens displays an extreme reliance upon star presence and authentic practical effects, to an extent that produces significant textual effects at a variety of levels. We here show how the film is premised upon and preoccupied with the authentic and authenticating presence of the main stars of the first wave of Star Wars productions (1977-83). However, on this outing we also expand what traditionally counts as a star 'actor' beyond the likes of Carrie Fisher and Harrison Ford courtesy of actor-network theory and recent 'media archaeology' trends. Indeed, Abrams proclaimed that his Star Wars film would hark back to a more 'authentic' aesthetic, by employing Panavision cameras and vintage Kodak stock, among other things, to capture images of the legacy stars, and other practical and animatronic effects. Consideration of these non-human 'actors' here helps us to re-perceive the role of 'zombie media' forms that move into composition with human stars to enhance the marketing and enjoyment of an authentic Star Wars experience.

A variety of adverse health effects have been identified as resulting from zinc deficiency. Zinc supplementation may therefore be indicated for certain individuals or populations. A rapid and straightforward means of assessing zinc status in humans would be of considerable medical benefit. In this study, the feasibility of measuring zinc levels in human fingernails or toenails using a portable x-ray fluorescence technique was assessed. Whole nail models (or phantoms) were constructed from resin, and dosed with various concentrations of zinc. These different concentration “nails” were cut into small slices of 4.4 ± 0.2 mm width. The combination of these various slices into different arrangements allowed the modeling of different time-dependent zinc exposure scenarios. A portable x-ray fluorescence device was tested using an “open beam” configuration having a beam diameter of ∼9 mm, and using a “weld mask” configuration with the beam width reduced to 2.9 mm. Minimum detection limits were determined to be 0.15 ± 0.01 ppm for the open beam, and 1.13 ± 0.08 ppm when using the weld mask. By scanning across the length of the model nails, it was demonstrated that differences in zinc levels deposited over time could be detected, and that the weld mask configuration was better suited to resolving spatial changes. The x-ray fluorescence approach was found to be highly sensitive for detecting zinc in nail, and capable of differentiating patterns of zinc uptake over time.

Although mining is a capital-intensive industry, its contribution to employment creation is generally praised as a leading local benefit to justify new or expanding extraction projects. However, labour substitution from automation and robotics is increasing in a wide range of modern mining processes. Such labour replacement is likely to intensify in the coming years due to advances and cost reductions in technology. Additionally, the COVID-19 pandemic also adds to the impetus of relying less on human interaction for critical operational processes. In this paper, we provide some insights on the global trends of automation/robotics in mining and discuss the main economic impacts that increasing human labour substitution could bring to mining communities, regions, and nations. We focus on mining automation/robotics impacts on jobs, income (including taxes), and regional inequality. We conclude by discussing policy options that governments could consider for mitigating these impacts, including the reskilling of miners and tax transfers.
