EFFICIENCY ANALYSIS OF HOSPITALS IN THE GREAT PLAINS: AN URBAN-RURAL COMPARISON
This study examined the efficiency of a sample of hospitals in the Great Plains using a nonparametric approach. Technical efficiency was less than either allocative or scale efficiency. Urban hospitals are relatively more efficient than rural hospitals with respect to all efficiency measures. Private hospitals are more efficient than others.Health Economics and Policy,

USING SATELLITE IMAGERY IN PREDICTING KANSAS FARMLAND VALUES
Can remotely sensed imagery improve hedonic land price models? A remotely sensed variable was added to a hedonic farmland value model as a proxy for land productivity. Land cover data were used to obtain urban and recreational effects as well. The urban and recreational effects were statistically significant but economically small. The remotely sensed productivity variable was statistically significant and economically large, indicating that knowing the "greenness" of the land increased the explanatory power of the hedonic price model. Thus, depending upon the cost of this information, including remotely sensed imagery in traditional hedonic land price models is economically beneficial.Land Economics/Use,
Property Tax Lids and the Effect on Kansas
Cross sectional time series data in a partial adjustment model examine local government behavior under an aggregate property tax levy limit and under Truth in Taxation in Kansas. Results indicate that the aggregate levy limit would have continued to restrict property tax revenue and spending had it not been replaced.Public Economics,
The effect of EGM2008-based normal, normal-orthometric and Helmert orthometric height systems on the Australian levelling network
This paper investigates the normal-orthometric correction used in the definition of the Australian Height Datum, and also computes and evaluates normal and Helmert orthometric corrections for the Australian National Levelling Network (ANLN). Testing these corrections in Australia is important to establish which height system is most appropriate for any new Australian vertical datum. An approximate approach to assigning gravity values to ANLN benchmarks (BMs) is used, where the EGM2008-modelled gravity field is used to "re-construct" observed gravity at the BMs. Network loop closures (for first- and second-order levelling) indicate reduced misclosures for all height corrections considered, particularly in the mountainous regions of south eastern Australia. Differences between Helmert orthometric and normal-orthometric heights reach 44 cm in the Australian Alps, and differences between Helmert orthometric and normal heights are about 26 cm in the same region. Normal orthometric heights differ from normal heights by up to 18 cm in mountainous regions >2,000 m. This indicates that the quasigeoid is not compatible with normal-orthometric heights in Australia
Height Systems and Vertical Datums: a Review in the Australian Context
This paper reviews (without equations) the various definitions of height systems and vertical geodetic datum surfaces, together with their practical realisation for users in Australia. Excluding geopotential numbers, a height system is a one-dimensional coordinate system used to express the metric distance (height) of a point from some reference surface. Its definition varies according to the reference surface chosen and the path along which the height is measured. A vertical geodetic datum is the practical realisation of a height system and its reference surface for users, nominally tied to mean sea level. In Australia, the normal-orthometric height system is used, which is embedded in the Australian Height Datum (AHD). The AHD was realised by the adjustment of ~195,000 km of spirit-levelling observations fixed to limited-term observations of mean sea level at multiple tide-gauges. The paper ends by giving some explanation of the problems with the AHD and of the differences between the AHD and the national geoid model, pointing out that it is preferable to recompute the AHD
Autistic adults’ experiences of managing wellbeing and implications for social prescribing
doi: 10.1080/09687599.2023.2263628Autistic people demonstrate poor outcomes on objective
measures of wellbeing, yet research centring lived experience
provides a more nuanced picture. There is growing support
for person-centred, holistic and community approaches to
enhancing wellbeing for autistic people. Social prescribing
may be one such approach. This qualitative study explored
the concept of wellbeing for autistic adults – including barriers and self-management – and the implications of this for
modifying social prescribing. It involved semi-structured interviews with 21 autistic adults in the UK. Reflexive thematic
analysis of the data supports research suggesting that
self-determination may underlie many aspects of wellbeing
for autistic people. The COVID-19 pandemic provided new
opportunities to develop wellbeing strategies but also had
negative impacts. Social prescribing could promote
self-determination by signposting autistic people to peer support opportunities building on intrinsic interests
Yallalie: a Buried Structure of Possible Impact Origin in the Perth Basin, Western Australia
An enigmatic buried structure, located in Mesozoic sedimentary rocks in the Perth Basin, Western Australia, was discovered in 1990 by Ampol Exploration. The basin-like Yallalie structure (centred on 30 26' 40.3'' S, 115 46' 16.4'' E) is circular in plan view and about 12 km in diameter. High resolution,seismic-reflection profiles across the structure show a basin-shaped area of chaotic reflections that extend to a depth of approximately 2 km below the surface. The structure has sharp boundaries with surrounding faulted, but otherwise relatively undisturbed, rocks. In the centre of the structure there is an uplifted area approximately 3?4 km across, similar to those described from complex meteorite impact structures. The seismically defined structure coincides with a circular topographic depression, and image processing of digital elevation data has allowed recognition of concentric and radial structures extending as far as 40 km from the centre of the depression. Gravity surveys show the structure to be associated with a positive gravity anomaly of about 30 gu. Aeromagnetic surveys have defined annular anomalies associated with the central uplifted section, and possibly margins, of the structure. A search for siderophile element enrichments (by neutron activation analysis) in the rocks of the structure, which would indicate the presence of a meteorite component, proved negative. Quartz grains in cores that penetrate the structure show the development of prismatic cleavage fractures and irregular, slightly curved planes formed by brittle fracture. An allochthonous breccia of Late Cretaceous rocks occurs a few kilometres west of the western margin of the structure. Quartz grains from a thin veneer of Tertiary sediments that drape the structure are essentially undeformed. However, multiple sets of closely spaced planar deformation features in quartz, characteristic of highly shocked rocks, have yet to be observed in the rocks of the Yallalie structure and the allochthonous breccia. The morphology of the Yallalie structure determined from topographic and geophysical data suggests strongly that it is of impact origin. Geological and geochemical evidence is equivocal, but is not inconsistent with this interpretation
