Estimating the Distribution of Japanese Encephalitis Vectors in Australia Using Ecological Niche Modelling

Recent Japanese encephalitis virus (JEV) outbreaks in southeastern Australia have sparked interest into epidemiological factors surrounding the virus’ novel emergence in this region. Here, the geographic distribution of mosquito species known to be competent JEV vectors in the country was estimated by combining known mosquito occurrences and ecological drivers of distribution to reveal insights into communities at highest risk of infectious disease transmission. Species distribution models predicted that Culex annulirostris and Culex sitiens presence was mostly likely along Australia’s eastern and northern coastline, while Culex quinquefasciatus presence was estimated to be most likely near inland regions of southern Australia as well as coastal regions of Western Australia. While Culex annulirostris is considered the dominant JEV vector in Australia, our ecological niche models emphasise the need for further entomological surveillance and JEV research within Australia

Japanese Encephalitis Enzootic and Epidemic Risks across Australia

Japanese encephalitis virus (JEV) is an arboviral, encephalitogenic, zoonotic flavivirus characterized by its complex epidemiology whose transmission cycle involves reservoir and amplifying hosts, competent vector species and optimal environmental conditions. Although typically endemic in Asia and parts of the Pacific Islands, unprecedented outbreaks in both humans and domestic pigs in southeastern Australia emphasize the virus’ expanding geographical range. To estimate areas at highest risk of JEV transmission in Australia, ecological niche models of vectors and waterbirds, a sample of piggery coordinates and feral pig population density models were combined using mathematical and geospatial mapping techniques. These results highlight that both coastal and inland regions across the continent are estimated to have varying risks of enzootic and/or epidemic JEV transmission. We recommend increased surveillance of waterbirds, feral pigs and mosquito populations in areas where domestic pigs and human populations are present

Seroprevalence of Influenza A Virus in Dromedaries in North-Western Nigeria

Although influenza A virus is endemic in wild waterfowl, domestic poultry, swine, humans, bats, cetaceans, dogs, and horses, there is a paucity of data on the potential role of camels in zoonotic transmission of the virus. To estimate the seroprevalence of the influenza A virus in camel populations, four local government areas of Nigeria that share an international border with the Niger Republic were selected. Blood samples from 184 one-hump camels (dromedaries) were collected and tested for influenza IgG antigen by ELISA. Each camel’s demographic variable, such as age, gender, location, production system, and usage, was recorded. The overall seroprevalence rate of influenza virus IgG in this study was 10.33% (95%CI: 6.33–15.66%). In the bivariate model, there was no significant difference in gender, age, site location and production system, except for usage. There was a significantly lower seroprevalence rate among camels used for labour (odds ratio (OR) = 0.34, 95% CI: 0.10–0.97) than those used for meat consumption; however, not after adjusting for other variables in the model. Increase surveillance through early detection, prediction, and risk assessment of pathogens in animal reservoirs and environmental contamination as One Health strategies to reduce potential human spillover is recommended. Molecular epidemiology studies could better elucidate the role of camels in the dynamics of disease transmission pathways

Planetary Rover Simulation for Lunar Exploration Missions

When planning planetary rover missions it is useful to develop intuition and skills driving in, quite literally, alien environments before incurring the cost of reaching said locales. Simulators make it possible to operate in environments that have the physical characteristics of target locations without the expense and overhead of extensive physical tests. To that end, NASA Ames and Open Robotics collaborated on a Lunar rover driving simulator based on the open source Gazebo simulation platform and leveraging ROS (Robotic Operating System) components. The simulator was integrated with research and mission software for rover driving, system monitoring, and science instrument simulation to constitute an end-to-end Lunar mission simulation capability. Although we expect our simulator to be applicable to arbitrary Lunar regions, we designed to a reference mission of prospecting in polar regions. The harsh lighting and low illumination angles at the Lunar poles combine with the unique reflectance properties of Lunar regolith to present a challenging visual environment for both human and computer perception. Our simulator placed an emphasis on high fidelity visual simulation in order to produce synthetic imagery suitable for evaluating human rover drivers with navigation tasks, as well as providing test data for computer vision software development.In this paper, we describe the software used to construct the simulated Lunar environment and the components of the driving simulation. Our synthetic terrain generation software artificially increases the resolution of Lunar digital elevation maps by fractal synthesis and inserts craters and rocks based on Lunar size-frequency distribution models. We describe the necessary enhancements to import large scale, high resolution terrains into Gazebo, as well as our approach to modeling the visual environment of the Lunar surface. An overview of the mission software system is provided, along with how ROS was used to emulate flight software components that had not been developed yet. Finally, we discuss the effect of using the high-fidelity synthetic Lunar images for visual odometry. We also characterize the wheel slip model, and find some inconsistencies in the produced wheel slip behaviour

Brief of Tribal Nations and Indian Organizations as Amici Curiae in Support of the Navajo Nation, U.S. Supreme Court Docket No. 21-1484

SUMMARY OF ARGUMENT: The Winters Doctrine recognizes and gives effect to the promises made by the United States in treaties, congressionally ratified agreements, and executive orders that Tribal Nations would retain permanent and viable homelands. These promises, made in exchange for the Tribal Nations’ cession of billions of acres of land, paved the way for the non-Indian settlement of the West. Although every tribal homeland is unique, invariably, each requires water to be livable. Applying the canons of construction this Court has developed as part of its federal Indian law jurisprudence, as well as the history and circumstances surrounding the creation of each individual reservation, the Winters Doctrine holds that the United States promised to provide water sufficient to fulfill the purposes for which the reservations were created. Concomitant with the promise to reserve water rights is the corresponding duty to protect and deliver on that promise and avoid rendering those rights meaningless through obstruction, depletion, or diversion to more junior users. In this way, the Winters Doctrine is a pathway for ensuring the United States fulfills its solemn obligations to Tribal Nations. The United States—through both Congress and the Executive—has repeatedly and expressly reaffirmed its understanding of these obligations. Petitioners here articulate no reason why the Lower Colorado River Basin should be treated differently. This Court should once again ensure the United States honors its obligations. In the 115 years since Winters v. United States, the Doctrine solidified into an integral part of the fabric that makes up Western water management. The Winters Doctrine forms the basis for extensive adjudication and settlement of claims by Tribal Nations to water rights. Today, millions of tribal and non-tribal citizens benefit from the certainty provided by the Winters Doctrine

Changing times in England: the influence on geography teachers’ professional practice

School geography in England has been characterised as a pendulum swinging between policies that emphasise curriculum and pedagogy alternately. In this paper, I illustrate the influence of these shifts on geography teacher's professional practice, by drawing on three “moments” from my experience as a student, teacher and teacher educator. Barnett's description of teacher professionalism as a continuous project of “being” illuminates how geography teachers can adapt to competing influences. It reflects teacher professionalism as an unfinished project, which is responsive, but not beholden, to shifting trends, and is informed by how teachers frame and enact policies. I argue that recognising these contextual factors is key to supporting geography teachers in “being” geography education professionals. As education becomes increasingly competitive on a global scale, individual governments are looking internationally for “solutions” to improve educational rankings. In this climate, the future of geography education will rest on how teachers react locally to international trends. Geography teacher educators can support this process by continuing to inform the field through meaningful geography education research, in particular in making the contextual factors of their research explicit. This can be supported through continued successful international collaboration in geography education research

Sense of entitlement to support for the reconciliation of employment and family life

This article explores young European women and men’s expectations of support - from the state and employers - for reconciling paid employment and family life. It is based on a qualitative study employing focus groups with young women and men in Norway, Sweden, Portugal, Ireland and the UK. Drawing on the concept of sense of entitlement, derived from social justice theory, it was expected that the type of welfare state and ‘gender contract’ that young adults have experienced will influence their sense of entitlement to support for work and family life. Findings indicate that participants perceived their entitlement to state and employer support differently across national context. However this is moderated by gender, parental and occupational status, and particularly by awareness of provisions in other countries in the case of state support, while perceived entitlement to employer support varies according to the specific policy considered, gender and perception of benefits to employers. Some implications for public policy makers and employers are discussed
