Enquiries should be addressed to the National Centre for Groundwater Research and Training, at Flinders University.Alice Springs’ public water supply is currently largely sourced from the Roe Creek borefield, located approximately 15 km south‐southwest of the town, in the north‐eastern section of the Amadeus Basin. However, at current extraction rates, water levels at Roe Creek are expected to decline beyond economical pumping depths by approximately 2050. By this time, it is expected that much of Alice Springs’ public water supply will be derived from a borefield within the Rocky Hill region. NT Portion 4704 was acquired by the Power and Water Corporation (PWC) for this purpose in 1996. Undoolya Rocky Hill Agricultural Block (NT Portion 1476) is located immediately northeast of NT Portion 4704, and the two blocks share a common boundary. Fodder crops have been grown intermittently on the agricultural block under centre pivot irrigation since the 1970s, with intensification of irrigation since 2002 when grapes were planted in the southeast of the block. Currently, there are about 60 ha of irrigated vineyards at this site. Proposals have been developed for expansion of onions onto areas of Undoolya Pastoral Lease, immediately south of the current vineyard development, and a water licence to facilitate this development has been granted

The hydrogeology of the Rocky Hill Region, Northern Territory

Enquiries should be addressed to the National Centre for Groundwater Research and Training, at Flinders University.The Rocky Hill area has been identified as a potential future bore field for Alice Springs town water supply, and in 1996 NT Portion 4704 was set aside for that purpose. The area has been the focus of several hydrogeological investigations over the past 50 years, most recently in 1998-2000 (Read and Paul, 2000, 2002). The current report updates the hydrogeological characterisation of this area, based on drilling and sampling of new test production bores within NT Portion 4704, and water level, geochemistry and geophysical surveys carried out within the Rocky Hill region within the last 20 years. This data will be used in a groundwater model which will assess the long-term sustainability of Rocky Hill as a future water supply for Alice Springs. The groundwater model will be the focus of a subsequent report

Drivers and barriers of international migration of doctors to and from the United Kingdom: a scoping review.

BACKGROUND: Many high-income countries are heavily dependent on internationally trained doctors to staff their healthcare workforce. Over one-third of doctors practising in the UK received their primary medical qualification abroad. Simultaneously, an average of around 2.1% of doctors leave the UK medical workforce annually to go overseas. The aim of this study was to identify the drivers and barriers of international migration of doctors to and from the UK. METHODS: A scoping review was conducted. We searched EMBASE, MEDLINE, CINAHL, ERIC and BEI in January 2020 (updated October 2021). Grey literature and citation searching were also carried out. Empirical studies reporting on the drivers and barriers to the international migration of doctors to and from the UK published in the English language from 2009 to present were included. The drivers and barriers were coded in NVivo 12 building on an existing framework. RESULTS: 40 studies were included. 62% were quantitative, 18% were qualitative, 15% were mixed-methods and 5% were literature reviews. Migration into and out of the UK is determined by a variety of macro- (global and national factors), meso- (profession led factors) and micro-level (personal factors). Interestingly, many of the key drivers of migration to the UK were also factors driving migration from the UK, including: poor working conditions, employment opportunities, better training and development opportunities, better quality of life, desire for a life change and financial reasons. The barriers included stricter immigration policies, the registration process and short-term job contracts. CONCLUSIONS: Our research contributes to the literature by providing a comprehensive up-to-date review of the drivers and barriers of migration to and from the UK. The decision for a doctor to migrate is multi-layered and is a complex balance between push/pull at macro-/meso-/micro-levels. To sustain the UK's supply of overseas doctors, it is vital that migration policies take account of the drivers of migration particularly working conditions and active recruitment while addressing any potential barriers. Immigration policies to address the impact of Brexit and the COVID-19 pandemic on the migration of doctors to and from the UK will be particularly important in the immediate future.

Gravel pits support waterbird diversity in an urban landscape

We assessed the benefit of 11 gravel pits for the settlement of waterbird communities in an urbanized area lacking natural wetlands. Gravel pits captured 57% of the regional species pool of aquatic birds. We identified 39 species, among which five were regionally rare. We used the Self Organizing Map algorithm to calculate the probabilities of presence of species, and to bring out habitat conditions that predict assemblage patterns. The age of the pits did not correlate with assemblage composition and species richness. There was a positive influence of macrophyte cover on waterbird species richness. Larger pits did not support more species, but species richness increased with connectivity. As alternative wetland habitats, gravel pits are attractive to waterbirds, when they act as stepping stones that ensure connectivity between larger natural and/or artificial wetlands separated in space

Demographics, distribution and experiences of UK clinical academic trainees using GMC NTS Survey data

Involvement in research plays an integral role in the delivery of high-quality patient care, benefitting doctors, patients and employers. It is important that access to clinical academic training opportunities are inclusive and equitable. To better understand the academic trainee population, distribution of academic posts and their reported experience of clinical training, we analysed 53 477 anonymous responses from General Medical Council databases and the 2019 National Training Survey. Academic trainees are more likely to be men, and the gender divide begins prior to graduation. There are very low numbers of international medical graduates and less than full-time academic trainees. A small number of UK universities produce a greater prevalence of doctors successfully appointed to academic posts; subsequent academic training also clusters around these institutions. At more senior levels, academic trainees are significantly more likely to be of white ethnicity, although among UK graduates, no ethnicity differences were seen. Foundation academic trainees report a poorer experience of some aspects of their clinical training placements, with high workloads reported by all academic trainees. Our work highlights important disparities in the demographics of the UK clinical academic trainee population and raises concerns that certain groups of doctors face barriers accessing and progressing in UK academic training pathways

Future supply of pediatric surgeons

Objective: To describe the future supply and demand for pediatric surgeons using a physician supply model to determine what the future supply of pediatric surgeons will be over the next decade and a half and to compare that projected supply with potential indicators of demand and the growth of other subspecialties. Background: Anticipating the supply of physicians and surgeons in the future has met with varying levels of success. However, there remains a need to anticipate supply given the rapid growth of specialty and subspecialty fellowships. This analysis is intended to support decision making on the size of future fellowships in pediatric surgery. Methods: The model used in the study is an adaptation of the FutureDocs physician supply and need tool developed to anticipate future supply and need for all physician specialties. Data from national inventories of physicians by specialty, age, sex, activity, and location are combined with data from residency and fellowship programs and accrediting bodies in an agent-based or microsimulation projection model that considers movement into and among specialties. Exits from practice and the geographic distribution of physician and the patient population are also included in the model. Three scenarios for the annual entry into pediatric surgery fellowships (28, 34, and 56) are modeled and their effects on supply through 2030 are presented. Results: The FutureDocs model predicts a very rapid growth of the supply of surgeons who treat pediatric patients - including general pediatric surgeon and focused subspecialties. The supply of all pediatric surgeons will grow relatively rapidly through 2030 under current conditions. That growth is much faster than the rate of growth of the pediatric population. The volume of complex surgical cases will likely match this population growth rate meaning there will be many more surgeons trained for those procedures. The current entry rate into pediatric surgery fellowships (34 per year) will result in a slowing of growth after 2025, a rate of 56 will generate a continued growth through 2030 with a likely plateau after 2035. Conclusions: The rate of entry into pediatric surgery will continue to exceed population growth through 2030 under two likely scenarios. The very rapid anticipated growth in focused pediatric subspecialties will likely prove challenging to surgeons wishing to maintain their skills with complex cases as a larger and more diverse group of surgeons will also seek to care for many of the conditions and patients which the general pediatric surgeons and general surgeons now see. This means controlling the numbers of pediatric surgery fellowships in a way that recognizes problems with distribution, the volume of cases available to maintain proficiency, and the dynamics of retirement and shifts into other specialty practice

Neutron-proton pairing in the N=Z radioactive fp-shell nuclei 56Ni and 52Fe probed by pair transfer

The isovector and isoscalar components of neutron-proton pairing are investigated in the N=Z unstable nuclei of the \textit{fp}-shell through the two-nucleon transfer reaction (p,$^3$He) in inverse kinematics. The combination of particle and gamma-ray detection with radioactive beams of $^{56}$Ni and $^{52}$Fe, produced by fragmentation at the GANIL/LISE facility, made it possible to carry out this study for the first time in a closed and an open-shell nucleus in the \textit{fp}-shell. The transfer cross-sections for ground-state to ground-state (J=0$^+$,T=1) and to the first (J=1$^+$,T=0) state were extracted for both cases together with the transfer cross-section ratios $\sigma$(0$^+$,T=1) /$\sigma$(1$^+$,T=0). They are compared with second-order distorted-wave born approximation (DWBA) calculations. The enhancement of the ground-state to ground-state pair transfer cross-section close to mid-shell, in $^{52}$Fe, points towards a superfluid phase in the isovector channel. For the "deuteron-like" transfer, very low cross-sections to the first (J=1$^+$,T=0) state were observed both for \Ni\phe\, and \Fe\phe\, and are related to a strong hindrance of this channel due to spin-orbit effect. No evidence for an isoscalar deuteron-like condensate is observed.Comment: 7 pages, 4 figure
