This research examines how school choice impacts school segregation. Specifically, this work demonstrates that even if parents do not take the racial demographics of schools into account, preference differences between Black and White parents for other school attributes can still result in segregation. These preference differences stem from motivational differences in pursuit of social status. Given that the de facto US racial hierarchy assigns Black people to a lower social status, Black parents are more motivated to seek schools that signal that they can improve their children's status. Simulations of parental school decisions at scale show that preference differences under an unmitigated school-choice policy lead to more segregated schools, impacting more than half a million US children for every 3-percentage-point increase in school-choice availability. In contrast, if Black and White parents have similar preferences, unmitigated school choice would reduce racial segregation. This research may inform public policy concerning school choice and school segregation.

Background: Over the past decades, self-directed models of care have been implemented throughout the world to support older people, including those with dementia, to live at home. However, there is limited information about how self-directed home care is experienced by older people with cognitive impairment and dementia, and how their thinking informs their care choices and quality of life.
Methods: We used the ASCOT-Easy Read, a staggered reveal method, talk aloud techniques, probing questions, and physical assistance to support users of self-directed home care in Australia with cognitive impairment and dementia to discuss their Social Care Related Quality of Life (SCRQoL).

The selection and expression of conspicuous colorations in animals is often related to anti-predation strategies and sociosexual communication. The giant river prawn, Macrobrachium rosenbergii (de Man, 1879) is a species with three male morphotypes that vary in claws' coloration and the size of the animals. It has been suggested that male reproductive quality might be associated to their coloration, but evidence is still conflicting.

Background: The severity of recent Coronavirus (COVID-19) pandemics has revealed the importance of development of inoculation strategies in case of limited vaccine availability. Authorities have implemented inoculation strategies based on perceived risk factors such as age and existence of other chronic health conditions for survivability from the disease. However, various other factors can be considered for identifying the preferred inoculation strategies depending on the vaccine availability and disease spread levels.

The broad application of various pesticides guarantees the development of agriculture all over the word but has ultimately led to their ubiquitous release into the environment as hazardous chemical residues. Diamide insecticides (DAIs) are regarded as new choice for prevention and protection of agricultural crops and city landscaping plants from the pests in more and more countries. However, their presence in fine particulate matter (PM) and associated health risks have not been studied.

Background: The Australian Rheumatology Association identified the use of imaging in patients with low back pain without indication of serious pathology as a low-value practice.
Aims: To determine the appropriateness of diagnostic lumbar spine imaging requests in patients with low back pain presenting to a Western Australian hospital's emergency department.
Methods: We conducted a retrospective review of all adult patients (18 years and older) who presented with low back pain to the Fiona Stanley Hospital emergency department from 1 July 2020 to 31 December 2020.
