description: We report on results of near-infrared and optical observations of the mm disk embedded in the Bok globule CB 26 (Launhardt & Sargent 2001). The near-infrared images show a bipolar reflection nebula with a central extinction lane which coincides with the mm disk. Imaging polarimetry of this object yielded a polarization pattern which is typical for a young stellar object surrounded by a large circumstellar disk and an envelope, seen almost edge-on. The strong linear polarization in the bipolar lobes is caused by single scattering at dust grains and allowed to locate the illuminating source which coincides with the center of the mm disk. The spectral energy distribution of the YSO embedded in CB 26 resembles that of a ClassI source with a luminosity of 0.5 L_sun.Using the pre-main-sequence evolutionary tracks and the stellar mass inferred from the rotation curve of the disk, we derive an age of the system of <10^6 yr. H_alpha and [SII] narrow-band imaging as well as optical spectroscopy revealed an Herbig-Haro object 6.15 arcmin northwest of CB 26 YSO 1, perfectly aligned with the symmetry axis of the bipolar nebula. This Herbig-Haro object (HH 494) indicates ongoing accretion and outflow activity in CB 26 YSO 1. Its excitation characteristics indicate that the Herbig-Haro flow is propagating into a low-density environment. We suggest that CB 26 YSO 1 represents the transition stage between embedded protostellar accretion disks and more evolved protoplanetary disks around T Tauri stars in an undisturbed environment.

The sandpile model on the complete split graph, Motzkin words, and tiered parking functions
Creators: name: Dukes, Mark
Publisher: name: arXiv
Year: 2020
Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: We classify recurrent states of the Abelian sandpile model (ASM) on the complete split graph. There are two distinct cases to be considered that depend upon the location of the sink vertex in the complete split graph. This characterisation of decreasing recurrent states is in terms of Motzkin words and can also be characterised in terms of combinatorial necklaces. We also give a characterisation of the recurrent states in terms of a new type of parking function that we call a tiered parking function. These parking functions are characterised by assigning a tier (or colour) to each of the cars, and specifying how many cars of a lower-tier one wishes to have parked before them. We also enumerate the different sets of recurrent configurations studied in this paper, and in doing so derive a formula for the number of spanning trees of the complete split graph that uses a bijective Prüfer code argument.

description: One of the main objectives of the 2003 CAP reform was that to enhance farm competitiveness and make farmers able to catch market signals and adjust their production level and specialization accordingly. The aim of the paper is to evaluate the effects of decoupling in Italy COP sector comparing the estimated results of some structural and economic indicators of a sample of farms before and after the 2003 reform using data from the Italian Institute of Statistics and of the Italian Farm Accountancy Data Network (FADN). The analysis shows an improvement of income in farms that kept COP production specialization through the years under study. At the same time, farms that opted for a different specialisation in the post reform period improved their economic performance. All this suggests that coupled support had become a constraint rather than an opportunity and that the 2003 reform, decoupling farm support from production, has contributed to a more efficient and market-oriented COP sector in Italy.

description: We present calculations of heavy quark and quarkonium production at CERN LEP2 in the k_T-factorization QCD approach. Both direct and resolved photon contribution are taken into account. The conservative error analisys is performed. The unintegrated gluon distribution in the photon is taken from the full CCFM evolution equation. The traditional color-singlet mechanism to describe non-perturbative transition of heavy quark pair into a final quarkonium is used. Our analisys covers polarization properties of heavy quarkonia at moderate and large transverse momenta. We find that the total and differential open charm production cross sections are consistent with the recent experimental data taken by the L3, OPAL and ALEPH collaborations. At the same time the DELPHI data for the inclusive J/Psi production exceed our predictions but experimental uncertainties are too large to claim a significant inconsistency. The bottom production in photon-photon collisions at CERN LEP2 is hard to explain within the k_T-factorization formalism.

Using galvanic stimulation to explore the role of vestibulospinal inputs on lower limb motoneurons
Creators: name: Kennedy, Paul Michael
Publisher: name: University of British Columbia
Year: 2009

description: Galvanic vestibular stimulation (GVS) is a technique used to activate the human vestibular system. The stimulus acts by altering the firing rate of the vestibular afferents (Goldberg et al. 1984), which leads to a change in the descending spinal inputs in the lateral vestibulospinal and reticulospinal tracts. These pathways provide a source of input onto spinal neurons that can affect the excitability of lower limb motoneurons. Galvanic stimulation, therefore, may be used to study the role of vestibulospinal input on lower limb motoneurons. The excitability of the motoneuron pool is affected by the length of the muscle fibers, so GVS may have differing effects at different muscle lengths. The strategy the nervous system adopts to activate muscles at different force producing lengths is still largely unknown. The effect of muscle length on motor unit recruitment was examined in the gastrocnemius muscle in Experiment 1. At a shortened muscle length, the onset of gastrocnemius motor unit activity occurred at significantly higher levels of plantar flexor torque. This may reflect inhibition of gastrocnemius motors units at shortened, non-optimal lengths. There are several pathways that might be involved in regulating the inhibitory inputs that act on the lower limb motoneuron pool, including the vestibulospinal tract. Experiments 2 and 3 provided evidence that a change in the vestibulospinal activity modified the amplitude of the passive ipsilateral soleus H-reflex. It was unclear, however, if this inhibition reflected a change in the activity of the la afferent pathway or motoneuron excitability. Consequently, Experiment 4 examined the effect of vestibulospinal influences on the discharge properties of single motor units in the gastrocnemius muscle. Activation of the vestibular system, using GVS, modified the onset and initial firing frequency of individual motor units at the shortened length but not at the long muscle length. This finding may reflect a change in the presynaptic inhibitory mechanisms that act on the motoneurons innervating muscle fibers that reach non-optimal force producing lengths. The results clearly demonstrate that GVS can alter the excitability of the triceps surae motoneuron pool. The descending vestibulospinal inputs operate to regulate inhibitory influences that act on the motoneuron pool.

We derive formulas of the momentum distributions of deuterons ($d$) and helions ($^3$He). We obtain the analytic expressions of the coalescence factor $B_A$'s ($B_2$ for $d$ and $B_3$ for $^3$He) as functions of the collision system size and the momentum. We apply the deduced results to p-p, p-Pb and Pb-Pb collisions to naturally explain the interesting behaviors of $B_A$ observed in experiments at the CERN Large Hadron Collider.

description: The paper focuses on the importance of the assumptions made about market structure and firm behaviors in empirical trade policy analysis. It does it with reference to the most recent changes in the EU import regime for bananas, namely the Economic Partnership Agreements and the December 2009 WTO agreement on bananas. The paper’s contribution to the literature on the issues addressed is threefold: it develops two original models which incorporate imperfectly competitive market structures in a spatial modeling framework; it provides an assessment of the degree of market power in international banana trade and, finally, it assesses how the analysis of the implications of the most recent changes in the EU import regimes for bananas is affected by the assumptions made regarding the prevailing market structure.
Hubble constant and sound horizon from the late-time Universe

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We measure the expansion rate of the recent Universe and the calibration scale of the baryon acoustic oscillation (BAO) from low-redshift data. BAO relies on the calibration scale, i.e., the sound horizon at the end of drag epoch $r_d$, which often imposes a prior of the cosmic microwave background (CMB) measurement from the Planck satellite. In order to make really independent measurements of $H_0$, we leave $r_d$ completely free and use the BAO data sets combined with the 31 observational $H(z)$ data, GW170817 and Pantheon sample of Type Ia supernovae. In $Λ$CDM model, we get $H_0=68.63^{+1.75}_{-1.77}$ km s$^{-1}$ Mpc$^{-1}$, $r_d=146.85^{+3.29}_{-3.77}$ Mpc. For the two model-independent reconstructions of $H(z)$, we obtain $H_0=68.02\pm1.82$ km s$^{-1}$ Mpc$^{-1}$, $r_d=148.18^{+3.36}_{-3.78}$ Mpc in the cubic expansion, and $H_0=68.58\pm1.76$ km s$^{-1}$ Mpc$^{-1}$, $r_d=148.02^{+3.63}_{-3.60}$ Mpc in the polynomial expansion. The values of Hubble constant $H_0$ and sound horizon $r_d$ are consistent with the estimate derived from the Planck CMB data assuming a flat $Λ$CDM model, but $H_0$ is in $2.4\sim2.6$ $σ$ tension with SH0ES 2019, respectively.

description: Within WTO agricultural negotiations, this paper deals with alternative criteria for the selection of sensitive products. Existing methodologies mostly rely on the analysis of tariffs and trade flows. On the contrary, assessments of the economic impacts on specific groups of stakeholders, namely the domestic agricultural sector, are missing or conducted at a high level of product aggregation. We hence develop a methodology that considers the effects of the selection of sensitive products on domestic agricultural prices. Our model, TRIMAG (Tariff Reduction Impact Model for Agriculture), defined at the 8-digit level, optimizes the domestic agricultural value added subject to a maximum number of sensitive tariff lines. The existing methodologies are applied to the Swiss tariff schedule and results compared with those of TRIMAG. Findings confirm the importance of developing sound economic criteria for the exante impact assessment of policy flexibilities. Furthermore, TRIMAG can be considered as a tariff aggregation tool that can be linked to agricultural simulation models that operate at a higher level of aggregation.

description: For the evaluation of the EU Rural Development Policy in the programming period 2007-2013, the European Commission has designed a Common Monitoring and Evaluation Framework (CMEF). Given a widespread lack of enthusiasm and the complexity of the CMEF, in this paper a comparative analysis of 22 evaluation methods of rural development policy is conducted in order to explore whether an alternative approach for the evaluation of the EU Rural Development Policy exists. The mixed case study approach is identified as potential alternative. This approach combines the analysis of data on input and output with in-depth interviews. First results of testing this method in the mid-term evaluation of the EU Rural Development Policy 2007-2009 in the Dutch NUTS2 region of Zeeland indicate that this approach might be a promising alternative to the CMEF. It is easier to implement and renders useful insight into the question why measures have been effective.

description: For policies that promote use of new technologies by farmers to be successful, it is important that farmers continue to use these technologies. Technology disadoption has not been analyzed in the literature widely and there is no theoretical model that analyzes technology disadoption. The objective of the current study is to provide a theoretical framework that explains the impact of farm size and uncertainty with respect to production technology on farmers’ decision to disadopt a new technology. Current study found that a negative relationship between farm size and disadoption technologies that were complement to other technologies that are used by larger farms. Also, the current study predicted that larger farmers are more likely to disadopt a new technology if a fixed replacement cost is required, where average replacement cost decreases with farm size. For the impact of technological uncertainty, the current paper found that if the variance of the profit from current technology or pratice increases, farmers become more likely to disadopt the current technology or the practices.

description: The Texas Panhandle relies largely on the Ogallala Aquifer for access to water for irrigated agricultural production. With current pumping rates and slow recharge rates, the aquifer will at some point in the future no longer be an economically viable source of water for agriculture. The objective of this study is to estimate the value of irrigated agriculture to the region. A hypothetical policy restriction is imposed which assumes a one hundred percent conversion to dryland agriculture. The study estimates the economic impact of such a change on producer income and the resulting socioeconomic impacts on communities in the region.

description: A self-calibration method was presented for a 3D Ultrasound Tomography System (USCT) in IEEE Ultrasonics Symposium (IUS) 2015 [1]. The method sequentially calibrates a complex USCT system with 2041 transducers based on time-of-flight (TOF) measurements. A direct evaluation of the calibration result was not possible due to unknown ground truth. In this work we present a method to estimate the upper boundary for the calibration accuracy. Evaluation with experiment data shows an estimated upper boundary of the mean error of 0.11 mm, which is smaller than the required accuracy of /4 = 0.15mm for high quality image reconstruction [2].

description: Ambient backscatter communications (AmBackComs) have been recognized as a spectrum- and energy-efficient technology for Internet of Things, as it allows passive backscatter devices (BDs) to modulate their information into the legacy signals, e.g., cellular signals, and reflect them to their associated receivers while harvesting energy from the legacy signals to power their circuit operation. {\color{black} However, the co-channel interference between the backscatter link and the legacy link and the non-linear behavior of energy harvesters at the BDs have largely been ignored in the performance analysis of AmBackComs. Taking these two aspects, this paper provides a comprehensive outage performance analysis for an AmBackCom system with multiple backscatter links}, where one of the backscatter links is opportunistically selected to leverage the legacy signals transmitted in a given resource block. For any selected backscatter link, we propose an adaptive reflection coefficient (RC), which is adapted to the non-linear energy harvesting (EH) model and the location of the selected backscatter link, to minimize the outage probability of the backscatter link. In order to study the impact of co-channel interference on both backscatter and legacy links, for a selected backscatter link, we derive the outage probabilities for the legacy link and the backscatter link. Furthermore, we study the best and worst outage performances for the backscatter system where the selected backscatter link maximizes or minimizes the signal-to-interference-plus noise ratio (SINR) at the backscatter receiver. We also study the best and worst outage performances for the legacy link where the selected backscatter link results in the lowest and highest co-channel interference to the legacy receiver, respectively.
Assessment of intraepidermal nerve fiber densities in 5 µm sections from arm and leg – a search for normative age-related values

description: Background and aims: Normative values are lacking regarding intraepidermal nerve fiber density (IENFD) in thin sections of 5 µm. Thus, we aimed to assess IENFD in thin sections in a healthy adult population as well as to investigate whether IENFD is related to age, sex, and site of excision.

Methods: Archival skin biopsies or excisions at the Department of Pathology, Lund, Sweden, from arm and leg were collected, re-sectioned, and immunohistochemically stained for Protein Gene Product 9.5 during 2020–2023. Nerve fibers were manually quantified in the 5 µm thin sections, and IENFD was compared between age groups, sex, and excision sites.

Results: IENFDs were evaluated in 602 samples from 591 healthy adults aged 18 to 97 years (295 women, 296 men). Median IENFD values are presented, stratified by age groups, sex, and excision sites. Higher IENFD was observed in the arm compared to the leg, as well as in the proximal compared to the distal leg, however not across all age groups. Levels of IENFD were lower among older adults, compared to all younger groups.

Conclusion: We have presented data on IENFD in thin 5 µm sections from a healthy adult population. Despite differences in IENFD observed across age groups, sexes, and excision sites, no strong conclusions regarding affecting factors could be drawn except that individuals > 65 years present with lower IENFD. Additional research and development of the method are warranted.

description: We present a study of the internal kinematics of two globular clusters, M10 (NGC 6254) and M71 (NGC 6838), using individual radial velocity (RV) measurements obtained from observations using the Hydra multi-object spectrograph on the WIYN 3.5 m telescope. We measured 120 RVs for stars in M10, of which 107 were determined to be cluster members. In M71, we measured 82 RVs and determined 78 of those measurements belonged to cluster members. Using the cluster members, we determine a mean RV of $75.9 \pm 4.0$ (s.d.) km s$^{-1}$ and $-22.9 \pm 2.2$ (s.d.) km s$^{-1}$ for M10 and M71, respectively. We combined the Hydra RV measurements with literature samples and performed a line-of-sight rotational analysis on both clusters. Our analysis has not revealed a statistically significant rotation in either of these clusters with the exception of the inner region (10\arcsec - 117\arcsec) of M10 for which we find hints of a marginally significant rotation with amplitude V$_{rot} = 1.14 \pm 0.18$ km s$^{-1}$. For M10, we calculate a central velocity dispersion of $σ_{0} = 5.44 \pm 0.61$ km s$^{-1}$, which gives a ratio of the amplitude of rotation to the central velocity dispersion $V_{rot}/σ_{0} = 0.21 \pm 0.04$. We also explored the rotation of the multiple stellar populations identified in M10 and M71 and found rotation (or lack thereof) in each population consistent with each other and the cluster global rotation signatures.

description: This paper presents a class of novel high-order accurate discontinuous Galerkin (DG) schemes for the compressible Euler equations under gravitational fields. A notable feature of these schemes is that they are well-balanced for a general hydrostatic equilibrium state, and at the same time, provably preserve the positivity of density and pressure. In order to achieve the well-balanced and positivity-preserving properties simultaneously, a novel DG spatial discretization is carefully designed with suitable source term reformulation and a properly modified Harten-Lax-van Leer contact (HLLC) flux. Based on some technical decompositions as well as several key properties of the admissible states and HLLC flux, rigorous positivity-preserving analyses are carried out. It is proven that the resulting well-balanced DG schemes, coupled with strong stability preserving time discretizations, satisfy a weak positivity property, which implies that one can apply a simple existing limiter to effectively enforce the positivity-preserving property, without losing high-order accuracy and conservation. The proposed methods and analyses are applicable to the Euler system with general equation of state. Extensive one- and two-dimensional numerical tests demonstrate the desired properties of these schemes, including the exact preservation of the equilibrium state, the ability to capture small perturbation of such state, the robustness for solving problems involving low density and/or low pressure, and good resolution for smooth and discontinuous solutions.

description: In a recent work [M. Jiang, M. Moeller, M. Berciu, and G. A. Sawatzky, Phys. Rev. B \textbf{101}, 035151 (2020)], the authors solved a model with a Cu impurity in an O-2p band as an approximation to the local electronic structure of a hole doped cuprate. One of their conclusions is that the ground-state has only $\sim 50$ \% overlap with a Zhang-Rice singlet (ZRS). This claim is based on the definition of the ZRS in a different representation, in which the charge fluctuations at the Cu site have been eliminated by a canonical transformation. The correct interpretation of the results, based on known low-energy reduction procedures for a multiband model including 3d$^8$ and 3d$^{10}$ configurations of Cu, indicates that this overlap is near 94 \%.

description: The purpose of this study was to evaluate changes in insulin sensitivity assessed by hyperinsulinemic-euglycemic clamp after 16 weeks of aerobic plus resistance training (Ae + RT), aerobic only training (Ae only), or usual care in a group of 28 randomly assigned postmenopausal women with type 2 diabetes (T2D). A second purpose was to relate improvements in insulin sensitivity to changes in abdominal subcutaneous and visceral AT (AT) cross-sectional area and thigh muscle cross-sectional area and density as assessed by single-image computed tomography (CT) scans. Glucose disposal during the hyperinsulinemic-euglycemic clamp was significantly increased by 77% after Ae + RT training (pre 2.36 ± 0.33, post 4.17 + 0.65 mg/kg/min, p=0.007), with no significant change seen in either the usual care group (pre 2.29 ± 0.46, post 2.36 + 0.46 mg/kg/min) or the Ae only group (pre 2.78 + 0.49, post 3.33 ± 0.64 mg/kg/min). The Ae + RT group demonstrated significant losses of 10.5% from the visceral AT area (pre 251.1 ± 22.9 cm², post 224.8 ± 20.0 cm², p<0.006), significant increases of 5.9% in muscle cross-sectional area (pre 207.7± 10.0 cm², post 213.6 ± 9.6 cm², p=0.017) and significant increases in average muscle density (pre 43.9 ± 1.7, post 46.4 + 1.2 HU, p<0.015) and the proportion of normal density muscle (pre 156.6 ± 12.8, post 167.1 ± 11.4 cm², p<0.001). The usual care group had a significant decrease in average muscle density (pre 47.1 + 1.1, post 46.0 ± 0.9 HU, p<0.004) and a significant increase in the proportion of low density muscle (pre 50.6 ± 4.2, post 53.8 ± 3.9 cm², p<0.015). Across all subjects, improved glucose disposal during the euglycemic clamp was significantly negatively associated with change in total abdominal AT area (r=-0.62, p<0.001), abdominal subcutaneous AT area (r=-0.64, p<0.001), visceral AT area (r=-0.32, p<0.047), and positively associated with muscle cross-sectional area (r=0.43, p<0.011), average muscle density (r=0.50 p=0.003) and normal density muscle (r=0.52, p<0.002). Significant associations remained between change in glucose disposal and change in muscle cross-sectional area (r=0.43, p<0.01), and area of normal density muscle (r=0.42, p<0.02) after controlling total abdominal AT area. These findings suggest that aerobic plus resistance training is an effective exercise strategy to improve insulin sensitivity in postmenopausal women with type 2 diabetes. The improved insulin sensitivity is related to loss of abdominal subcutaneous and visceral AT and to increased muscle cross-sectional area and density.

description: 5G and beyond networks will use, for the first time ever, the millimeter wave (mmWave) spectrum for mobile communications. Accurate performance evaluation is fundamental to the design of reliable mmWave networks, with accuracy rooted in the fidelity of the channel models. At mmWaves, the model must account for the spatial characteristics of propagation since networks will employ highly directional antennas to counter the much greater pathloss. In this regard, Quasi-Deterministic (QD) models are highly accurate channel models, which characterize the propagation in terms of clusters of multipath components, given by a reflected ray and multiple diffuse components of any given Computer Aided Design (CAD) scenario. This paper introduces a detailed mathematical formulation for QD models at mmWaves, that can be used as a reference for their implementation and development. Moreover, it compares channel instances obtained with an open source NIST QD model implementation against real measurements at 60 GHz, substantiating the accuracy of the model. Results show that, when comparing the proposed model and deterministic rays alone with a measurement campaign, the Kolmogorov-Smirnov (KS) test of the QD model improves by up to 0.537.

description: Average producer practice reveals that the expected returns are greater from dual-purpose wheat grown for both forage and grain than for grain-only wheat. Variety trials report an 11 bushel per acre yield advantage and hence economic advantage for grain-only. Research was conducted to reconcile the inconsistency.
Exploring Jet Substructure in Semi-visible jets

description: Semi-visible jets arise in strongly interacting dark sectors, where parton evolution includes dark sector emissions, resulting in jets overlapping with missing transverse momentum. The implementation of semi-visible jets is done using the Pythia Hidden valley module to duplicate the QCD sector showering. In this work, several jet substructure observables have been examined to compare semi-visible jets and light quark/gluon jets. These comparisons were performed using different dark hadron fraction in the semi-visible jets (signal). The extreme scenarios where signal consists either of entirely dark hadrons or visible hadrons offers a chance to understand the effect of the specific dark shower model employed in these comparisons. We attempt to decouple the behaviour of jet-substructure observables due to inherent semi-visible jet properties, from model dependence owing to the existence of only one dark shower model as mentioned above.

description: Potassium (K) and phosphorus (P) application to sunflower (Helianthus annus L.) reduced cost of production, increased seed oil and protein concentration, yield and net returns on the K and P deficient soils in Northwest Pakistan. Field experiment was conducted at the New Developmental Research Farm of NWFP (North West Frontier Province) Agricultural University Peshawar, Pakistan during summer 2006. The experiment was carried out in a randomized complete block design with split plot arrangements using three replications. Six levels of K (0, 25, 50, 75, 100 and 125 kg ha-1) were kept in main plots while four levels of P (0, 45, 90 and 135 kg ha-1) were kept in sub-plots. Increase in K and P levels enhanced seed oil concentration, on the other hand, increase in P level increased seed protein concentration but increase in K level decreased seed protein concentration. Both oil and protein yields per unit area increased significantly with increase in K and P levels. The increase in oil and protein yields of sunflower was mainly attributed to the improvement in yield components and significant increase in seed yield. The highest net returns of Rs. 25268 (grain yield basis) and Rs. 31274 (oil yield basis) was obtained from those plots that received a combination of 100 kg K + 45 kg P ha-1. Application of 100 kg K ha-1 + 45 kg P ha-1 was therefore, recommended for profitable sunflower production in the agro-climatic conditions in Northwest Pakistan.

Maxilliped unsegmented, armed with 10 medial setae and 1 apical seta. Legs 1–4 with 3-segmented rami. Inner coxal seta absent in legs 1–4. Leg 1 with inner distal spine on basis. Leg 4 without outer element on first exopodal segment. Armature formula for legs 1–4 as follows:
Leg 5 rudimentary, bilobed, with 1 seta on apex of each lobe.
Type species. Gosbia pusilla gen. et sp. nov., by original designation.
Etymology. The generic name Gosbia is an anagram of BIOGAS (Biologie Gascogne) which was a French deep-sea research program. Gender feminine.
Remarks. Bysone Stock, 1967 and Gosbia gen. nov. have similarly reduced setal armature on the mandible and themaxillule, andbothhavearudimentaryleg 5. However, Gosbia gen. nov. can be separated from Bysone and other similar genera, such as Thoracodelphys and Sesir, by the presence of 3-segmented rami in all swimming legs and by the presence of a large seta representing the exopod on the antenna. In Bysone and related genera, the endopods of legs 2–4 are all 2-segmented, and the antenna either lacks any trace of the exopod, or retains only a minute setal vestige.

description: Estimates of the compensating surplus generated by changes in non-marketed environmental amenities can be estimated using stated preference valuation techniques. These are typically framed in terms of WTP tradeoffs, even if the situation of interest involves a property right vestment that calls for a WTA question. The differences created by the two questioning formats are explored in this paper using the results of two choice modelling applications. Both applications were framed on the potential for irrigation development and environmental losses in the Fitzroy River Basin, Central Queensland. The scenarios used in the applications differed only in that they used alternatively WTP and WTA questioning formats. The results indicate that robust models could not be constructed from either WTP- or WTA-based data sets when only two alternatives were used in the choice sets. In contrast, a strongly fitting model was derived from WTP-based data where three alternatives formed the choice sets.
