\u3ci\u3eConcepcion\u3c/i\u3e and Preemption Under the Federal Arbitration Act

The Supreme Court held in AT&T Mobility v. Concepcion that a California law declaring class arbitration waivers unconscionable was preempted because it stood as an obstacle to the accomplishment and execution of the full purposes and objectives of the Federal Arbitration Act. The Court\u27s Concepcion decision was necessarily based on implied preemption, because the FAA contains no express preemption clause and because there was no textual conflict between the FAA and the California law.

Seeing the world through others’ minds: inferring social context from behaviour

Past research tells us that individuals can infer information about a target’s emotional state and intentions from their facial expressions (Frith & Frith, 2012), a process known as mentalising. This extends to inferring the events that caused the facial reaction (e.g. Pillai, Sheppard, & Mitchell, 2012; Pillai et al., 2014), an ability known as retrodictive mindreading. Here, we enter new territory by investigating whether or not people (perceivers) can guess a target’s social context by observing their response to stimuli. In Experiment 1, perceivers viewed targets’ responses and were able to determine whether these targets were alone or observed by another person. In Experiment 2, another group of perceivers, without any knowledge of the social context or what the targets were watching, judged whether targets were hiding or exaggerating their facial expressions; and their judgments discriminated between conditions in which targets were observed and alone. Experiment 3 established that another group of perceivers’ judgments of social context were associated with estimations of target expressivity to some degree. In Experiments 1 and 2, the eye movements of perceivers also varied between conditions in which targets were observed and alone. Perceivers were thus able to infer a target’s social context from their visible response. The results demonstrate an ability to use other minds as a window onto a social context that could not be seen directly

Detecting Fauna Habitat in Semi-Arid Grasslands Using Satellite Imagery

Managing grasslands for biodiversity conservation is a relatively recent phenomenon and there is uncertainty over the most effective strategy. Past research has found that intermediate levels of disturbance (e.g. burning or grazing) may be required to maintain the natural mosaic of small-scale patterning required for a diverse range of flora and fauna species. For sustainable grassland management, appropriate methods of spatial assessment and temporal monitoring are required, to facilitate understanding of how past and present climate, land management and landscape features influence vegetation structure. Due to the expense and time-consuming nature of conventional ground-based monitoring, satellite remote-sensing techniques offer a feasible approach

Funding for mental health research: the gap remains

Objectives: To examine the levels and growth rates of absolute funding to mental health research from 2001 to 2010, compared with other National Health Priority Areas (NHPAs), and the relative rate of mental health funding compared with other NHPAs, by taking disease burden into account. The quality of Australian research in mental health was also examined using objective indicators of research strength. Design and setting: Retrospective analysis of levels of funding overall and as a function of mental health domains using data from the National Health and Medical Research Council, with and without adjustment for burden of disease. A keyword analysis was used to assess the success rate of mental health project grant applications. Objective indicators of the quality of Australian mental health research were sought from citation indicators. Main outcome measures: Funding for mental health research relative to disease burden; funding according to disease category; project grant success rates. Results: Using actual and adjusted figures, mental health research received a lower proportion of health funding than other NHPAs, including cancer, diabetes and cardiovascular disease. Research projects into substance misuse and autism were proportionately better funded than those in anxiety, depression or schizophrenia. A significant proportion of mental health research funding was awarded to research into ageing. Citation data indicated that mental health research in Australia performed better than research in neuroscience, clinical medicine, microbiology, and pharmacology and toxicology, and at a comparable level to immunology research, despite poor levels of funding. Conclusions: Low levels of funding for mental health research appear to be largely attributable to low capacity. Mental health research in Australia is of high quality, and efforts are needed to build capacity

Intestinal Parasites in the Neolithic Population Who Built Stonehenge (Durrington Walls, 2500 BCE)

Durrington Walls was a large Neolithic settlement in Britain dating around 2500 BCE, located very close to Stonehenge and likely to be the campsite where its builders lived during its main stage of construction. Nineteen coprolites recovered from a midden and associated pits at Durrington Walls were analysed for intestinal parasite eggs using digital light microscopy. Five (26%) contained helminth eggs, 1 with those of fish tapeworm (likely Dibothriocephalus dendriticus) and 4 with those of capillariid nematodes. Analyses of bile acid and sterol from these 5 coprolites show 1 to be of likely human origin and the other 4 to likely derive from dogs. The presence of fish tapeworm reveals that the Neolithic people who gathered to feast at Durrington Walls were at risk of infection from eating raw or undercooked freshwater fish. When the eggs of capillariids are found in the feces of humans or dogs it normally indicates that the internal organs (liver, lung or intestines) of animals with capillariasis have been eaten, and eggs passed through the gut without causing disease. Their presence in multiple coprolites provides new evidence that internal organs of animals were consumed. These novel findings improve our understanding of both parasitic infection and dietary habits associated with this key Neolithic ceremonial site

Intestinal parasites at the Late Bronze Age settlement of Must Farm, in the fens of East Anglia, UK (9th century B.C.E.).

Little is known about the types of intestinal parasites that infected people living in prehistoric Britain. The Late Bronze Age archaeological site of Must Farm was a pile-dwelling settlement located in a wetland, consisting of stilted timber structures constructed over a slow-moving freshwater channel. At excavation, sediment samples were collected from occupation deposits around the timber structures. Fifteen coprolites were also hand-recovered from the occupation deposits; four were identified as human and seven as canine, using fecal lipid biomarkers. Digital light microscopy was used to identify preserved helminth eggs in the sediment and coprolites. Eggs of fish tapeworm (Diphyllobothrium latum and Diphyllobothrium dendriticum), Echinostoma sp., giant kidney worm (Dioctophyma renale), probable pig whipworm (Trichuris suis) and Capillaria sp. were found. This is the earliest evidence for fish tapeworm, Echinostoma worm, Capillaria worm and the giant kidney worm so far identified in Britain. It appears that the wetland environment of the settlement contributed to establishing parasite diversity and put the inhabitants at risk of infection by helminth species spread by eating raw fish, frogs or molluscs that flourish in freshwater aquatic environments, conversely the wetland may also have protected them from infection by certain geohelminths

A low carbon footprint approach to the reconstitution of plastics into 3D-printer filament for enhanced waste reduction

In this study we aim to investigate recycling of waste plastics products into filaments for use in a typical FDM 3D printing system. We investigate the parameters relating to control of the filament thickness to a variety of different plastic types, which include HDPE and ABS. Following filament generation, parameters were investigated to optimise the print parameters to produce a variety of demonstration models, which test the print resolution. Results suggest that the proposed supply chain can allow for highly repeatable ABS and HDPE filament generation with a diameter of 1.74 ± 0.1mm and 1.65 ± 0.1mm respectively. Ultimately, the production of usable filaments can provide a viable means of consuming waste plastics and reducing the burden of increased landfill.
