The white-seared landscape: Walkabout as iconic Australian counterculture

Nicolas Roeg’s Walkabout, a 1971 Australian New Wave film, has ignited and continues to ignite a deep desire in its audience to ruminate and engage with Aboriginal political discourse. This seminal work emerged out of social unrest for the injustices performed on Aborigines at the time, and made a definitive mark on how Australian’s think about race relations, intercultural understanding, and the place of empathy and thoughtfulness in a shifting and vibrant political landscape. Through the film, Roeg highlights the importance of sacred land and cultural heritage to the Aboriginal people, and the obligation white Australia has to respect and appreciate such a deep and fundamental component of the continent’s history

An Investigation Into Magnetic Structures in The SolarWind Plasma Using Ulysses Data

The solar environment has long been studied from Earth by the likes of Richard Carrington and company. Since the dawn of the space age, spacecraft have been sent to space to learn more about the solar wind. The European Space Agency’s (ESA) Ulysses spacecraft, launched in 1990, was designed to observe the sun from a polar vantage point. With the instruments on board, Ulysses gave space and plasma physicists a unique opportunity to study the plasma around the sun. We have developed search algorithms to detect shocks and solitons within the solar wind using data from Ulysses.The algorithms can detect a variety of structures in the solar wind and we show, in detail, three events worth further investigation. Applying these algorithms to the 19 year data set from Ulysses will likely reveal many more structures worthy of study

Towards large-cohort comparative studies to define the factors influencing the gut microbial community structure of ASD patients.

Differences in the gut microbiota have been reported between individuals with autism spectrum disorders (ASD) and neurotypical controls, although direct evidence that changes in the microbiome contribute to causing ASD has been scarce to date. Here we summarize some considerations of experimental design that can help untangle causality in this complex system. In particular, large cross-sectional studies that can factor out important variables such as diet, prospective longitudinal studies that remove some of the influence of interpersonal variation in the microbiome (which is generally high, especially in children), and studies transferring microbial communities into germ-free mice may be especially useful. Controlling for the effects of technical variables, which have complicated efforts to combine existing studies, is critical when biological effect sizes are small. Large citizen-science studies with thousands of participants such as the American Gut Project have been effective at uncovering subtle microbiome effects in self-collected samples and with self-reported diet and behavior data, and may provide a useful complement to other types of traditionally funded and conducted studies in the case of ASD, especially in the hypothesis generation phase

Best Practices for Low-Cost Safety Improvements on Iowa’s Local Roads

Many good maintenance practices are done routinely to ensure safe travel on low-volume local roads. In addition, there are many specific treatments that may go beyond the point of routine maintenance and in fact provide additional safety benefits with a relatively low price tag. The purpose of this publication is to try to assemble many of these treatments that are currently practiced in Iowa by local agencies into one, easy-to-reference handbook that not only provides some clarity to each treatment with photos and narrative, but also features references to agencies currently using that technique. Some strategies that are utilized by Iowa, other states, and are topics of research have also been included to allow the user more information about possible options. Even though some areas overlap, the strategies presented have been grouped together in the following areas: Signing and Delineation, Traffic Calming, Pavement Marking and Rumble Strips/Stripes, Roadside and Clear Zone, Guardrail and Barriers, Lighting, Pavements and Shoulders, Intersections, Railroad Crossings, Bridges and Culverts, and Miscellaneous. The intention is to make this a “living” document, which will continue to be updated and expanded periodically as other existing practices are recognized or new practices come into being
