The environmental performance assessment of civil construction projects : an expert rule approach
Creators: name: Ng, Shao Kwan
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis presents a method of assessing the environmental performance of civil contractors on major construction projects. The motivation for the research leading to the development of the method was recognition of the increasing need for civil construction companies to self-regulate the environmental management aspects of their work, which in turn requires performance evaluation in order to achieve continual improvement. The thesis starts by briefly reviewing the environmental management aspects of civil construction projects in Tasmania. It highlights the emergence of environmental management plans and associated commitments as part of the project approval process. The widespread adoption of environmental management systems by civil construction firms is also discussed, and attributed in part to government downsizing over the past decade. The proposed environmental performance assessment method aims to provide civil construction companies with a tool to assist continual improvement. The method is based on examining the company's compliance with its environmental management system, and also with the project's environmental management plan. A risk management approach is used to select the leading commitments for a given project associated with the company's environmental management system, and the project's environmental management plan. Site visits to major Tasmanian civil construction projects were carried out to develop these ideas. The visits were to the Abt Railway construction site and to the Westbury-Hagley bypass construction site. The visits were undertaken with the help of the State Department of Infrastructure Energy and Resources (DIER), and of the civil construction and consulting engineering companies associated with the projects. The new evaluation method is illustrated by application to these two projects, and shown to be an effective tool for assessing the environmental performance of the civil contractor regarding specific project commitments. The research also examined ways to aggregate individual performance scores. An expert rule approach is shown to provide a natural and elegant alternative to the traditional weighted average method of combining scores. In particular, an expert rule approach offers the advantage that an individual poor score can be flagged by the aggregation process, and not masked by good performance scores for other commitments. The thesis concludes by discussing how best to develop the method into an operational tool through trials carried out in association with local civil construction compames. The research is supported by two unpublished site visit reports, and two refereed conference papers. The thesis and its associated publications have been very favourably reviewed by State Government environmental and project management specialists familiar with the case study projects.

description: We investigate the Dirichlet-scalar equivalent of Casimir-Polder forces between an atom and a surface with arbitrary uniaxial corrugations. The complexity of the problem can be reduced to a one-dimensional Green's function equation along the corrugation which can be solved numerically. Our technique is fully nonperturbative in the height profile of the corrugation. We present explicit results for experimentally relevant sinusoidal and sawtooth corrugations. Parameterizing the deviations from the planar limit in terms of an anomalous dimension which measures the power-law deviation from the planar case, we observe up to order-one anomalous dimensions at small and intermediate scales and a universal regime at larger distances. This large-distance universality can be understood from the fact that the relevant fluctuations average over corrugation structures smaller than the atom-wall distance.

Unsteady operation of the Francis turbine
Creators: name: Ng, TB
Publisher: name: University Of Tasmania
Year: 2023

description: Increasing interconnection of individual power systems into major grids has imposed more stringent quality assurance requirements on the modelling of hydroelectric generating plant. This has provided the impetus for the present study in which existing industry models used to predict the transient behaviour of the Francis-turbine plants are reviewed. Quasi-steady flow models for single- and multiple-turbine plants developed in MATLAB Simulink are validated against field test results collected at Hydro Tasmania's Mackintosh and Trevallyn power stations. Nonlinear representation of the Francis-turbine characteristics, detailed calculation of the hydraulic model parameters, and inclusion of the hydraulic coupling effects for multiple-machine station are found to significantly improve the accuracy of predictions for transient operation. However, there remains a noticeable phase lag between measured and simulated power outputs that increases in magnitude with guide vane oscillation frequency. The convective lag effect in flow establishment through the Francis-turbine draft tube is suspected as a major contributor to this discrepancy, which is likely to be more important for hydro power stations with low operating head and short waterway conduits. To further investigate these effects, the steady flow in a typical Francis-turbine draft tube without swirl is analysed computationally using the commercial finite volume code ANSYS CFX. Experimental studies of a scale model draft tube using air as the working medium are conducted to validate and optimise the numerical simulation. Surprisingly, numerical simulations with a standard k-˜í¬µ turbulence model are found to better match experimental results than the steady-flow predictions of more advanced turbulence models. The streamwise pressure force on the draft tube is identified as a quantity not properly accounted for in current industry models of hydro power plant operation. Transient flow effects in the model draft tube following a sudden change in discharge are studied computationally using the grid resolution and turbulence model chosen for the steady-flow analysis. Results are compared with unsteady pressure and thermal anemometry measurements. The three-dimensional numerical analysis is shown to predict a longer response time than the one-dimensional hydraulic model currently used as the power industry standard. Convective lag effects and fluctuations in the draft tube pressure loss coefficient are shown to largely explain the remaining discrepancies in current quasi-steady predictions of transient hydro power plant operation.

description: The STEREO mission has been providing stereoscopic view of the filament eruptions in EUV wavelengths. The most extended view during filament eruptions is seen in He II 304 Åobservations, as the filament spine appears darker and sharper. The projected filament width appears differently when viewed from different angles by STEREO satellites. Here, we present a method for estimating the width and inclination of the filament sheet using He II 304 Å observations by STEREO-A and B satellites from the two viewpoints. The width of the filament sheet, when measured from its feet to its apex, gives estimate of filament height above the chromosphere.

description: This study makes a contribution to the land redistribution policy, which is presently not only one of the most definitive political and development issues, but perhaps the most intractable in South Africa. The study develops and uses a mathematical model for regionalised farm-level resource use and output supply response to show that the current policy requires more economic imperatives, as it tends towards smallholder agriculture that cannot produce adequate yields to meet either domestic demand or a tradable volume. Given the challenges of a free market and the fact that the settled small-scale, resource-poor (mainly black) farmers are less efficient compared to large-scale (mainly white) farmers from whom government transfers land, the study compares and prescribes land redistribution strategy that considers equity with efficiency. The study further suggests that agricultural land may act as a safety net for the poor, where the efficiency argument does not hold.

description: We investigate spin-one color superconductivity of a single quark flavor using the Ginzburg-Landau theory. First we examine the classic analysis of Bailin and Love and show that by restricting to the so-called inert states, it misses the true ground state in a part of the phase diagram. This suggests the use of the more general, noninert states in particular within three-flavor quark matter where the color neutrality constraint imposes stress on the spin-one pairing and may disfavor the symmetric color-spin-locked state. In the second part of the paper we show that, in analogy to some ferromagnetic materials, lack of space-inversion symmetry leads to a new term in the Ginzburg-Landau functional, which favors a spatially nonuniform long-range ordering with a spiral structure. In color superconductors, this new parity-violating term is a tiny effect of weak-interaction physics. The modified phase diagram is determined and the corresponding ground states for all the phases constructed. At the end, we estimate the coefficient of the new term in the free energy functional, and discuss its relevance for the phenomenology of dense quark matter.

Localisation and navigation : applying biological principles in mobile robotics
Creators: name: Ollington, R
Publisher: name: University Of Tasmania
Year: 2023

description: Recently, there has been a significant effort to apply behavioural and anatomical studies ofhippocampal place learning in rodents and other animals to the problem of robot localisation and mapping. The stated purpose of these recent experiments is twofold. Firstly, it is hoped that a study of this material will lead to improved algorithms for mobile robotics. Secondly, the behaviour of these new algorithms may be studied to evaluate psychological theories, and aid in the development of new theories. This thesis builds on these experiments by developing a complete localisation and navigational system for a simulated mobile robot. In order to provide a complete and efficient system, several new algorithms were developed. Firstly, a method for preprocessing input was required, thus the adaptive response function neuron (ARFN) was developed. This neuronal model is able to identify similar input patterns, while discriminating between conceptually different sensory experiences. ARFNs learn a locally tuned response to input patterns, and are able to adapt the centre, width and shape of each input's response function on-line. These cells demonstrate one simple way that neurons in the cerebral cortex may learn a locally tuned response to input. Secondly, a place cell system was developed for localisation. The new system provides a simple technique for establishing place cell firing based on odometric information and the current view (as captured by ARFNs). This system enables the robot's position to be accurately estimated, even in the presence of random and systematic odometric errors. The main advantage of the new system is that it allows certain topological assumptions to be made a priori, thus accelE;rating the training of downstream navigational systems. This prior knowledge may help explain the dead reckoning abilities of some animals and provides new insights into the place cell system in general. Finally, a novel reinforcement learning algorithm was developed for goal independent navigation in complex environments. The new algorithm, called Concurrent Q-Learning (CQL), learns a value function for all goals simultaneously, and updates this value function more efficiently than similar algorithms. This is particularly true in dynamic environments, where CQL is shown to outperform other reinforcement learning algorithms. Unlike CQL, alternative methods for achieving goal-independent navigation, such as coordinate learning, cannot easily be applied to complex environinents. Furthermore, the performance of CQL shows that coordinate learning is not necessary to solve behavioural tasks previously thought to require an abstract vector representation. While the focus of this research has been on spatial cognition, the hippocampus is also thought to be fundamental to other basic thought processes. Therefore, it is hoped that this research may stimulate further study not only into animal and robotic navigation, but also into biological and artificial intelligence in general.

description: We investigate in this paper the participation of farms in the agri-environmental measure â€œextensive grasslandâ€ and the consequences on land use in the case study area Ostprignitz-Ruppin in the federal state of Brandenburg in Germany. We first vary the level of agri-environmental payments (AEP) per hectare in the framework of Agenda 2000. Then we investigate the impacts of the actual decoupling policy which includes the possibility of keeping the land in good agricultural and environmental conditions. For this purpose we use the agent-based model AgriPoliS whose dynamic nature offers an original way to understand farmersâ€™ individual decisions to participate or not in this agri-environmental measure. The simulations show that AEP can avoid land abandonment to some extent. However regional decoupled payments put the relevance of this measure into question, as farmers reduced their participation after the reform of the policy.

Convention and the intensional concepts
Creators: name: Hadley, Robert Francis
Publisher: name: University of British Columbia
Year: 2011

description: The central theme of this thesis is that our use of language is guided by linguistic conventions or linguistic rules. Substantial arguments are produced to show that we must suppose language use to be guided by such conventions. Further arguments are produced to show that the theory that language use is convention-guided can explain many facts which have not yet received satisfactory explanations. Some of the main explanatory advantages of the convention-guidedness theory are: 1) it explains the analytic-synthetic distinction. 2) it enables us to state, with fair precision, exactly what a concept analysis is, and how it is possible for people to use concepts without knowing the analysis of those concepts. 3) it explains why people's intuitions about meaning and synonomy agree to such a large extent. 4) it explains how linguistic descriptions of experience are justified by experience. 5) it explains why all the objects denoted by a given term often share some set of properties which can, fairly easily, be described. One problem which has plagued earlier theories of linguistic convention has been the lack of any acceptable principle of individuation for linguistic rules. In this thesis a satisfactory principle of individuation for linguistic rules is developed. Similiarities are noted between the way computer behaviour is guided by a program and human linguistic behaviour is guided by linguistic rules. It is noted that very precise criteria exist for the identity of computer programs, and these criteria suggest criteria for the identity of linguistic rules. Other questions investigated in this thesis are: a) Whether Quine is right in thinking that absolutely any of our beliefs might be abandoned in the face of experiences which conflict with an accepted theory. It is concluded that this doctrine of Quine's is mistaken. b) Whether the notion of "logical constant" can be elucidated with any precision. This question is answered negatively. It is shown that we must take the general concepts of necessity and validity as fundamental building blocks in intellectual inquiry. c) Whether all necessary truths are analytic. It is shown that the answer to this question is to a large extent arbitrary. d) Whether necessary truths are the result of linguistic convention. It is shown that necessary truths are not, in any interesting sense, the result of convention.

description: Deer researchers at AgResearch are incorporating social researchers in their work to gain an understanding of New Zealand deer farmersâ€™ level of environmental awareness in order to provide a platform for future adoption of land care techniques. This research was designed to understand the level of environmental awareness deer farmers had with regards to specific sustainable farming practices in two regions of New Zealand. Farmers were asked for their experiences with the following practices; wallowing, waterway fencing, wintering management and fence pacing. Our findings indicate that deer farmers were generally aware of environmental concerns however, the level of awareness was influenced by their specific farm context. This included, but was not limited to, factors such as topography and soil type. Many believed they were doing the â€˜best they couldâ€™ and therefore did not feel they needed to adopt new environmental practices.

Thermal death time studies on anaerobic spore formers : investigations on Australian strains of clostridium botulinum.
Creators: name: Olsen, Albert Mervyn
Publisher: name: University Of Tasmania
Year: 2023

description: Canning is the general term applied to the heat preservation Of foodstuffs in sealed containers from which air is partially excluded. The heat treatment (process) is given in order to destroy the normal Microbial flora of the fresh food that would otherwise grow and spoil it. Of the various types of micro-organisms found on fresh material, vegetative forms and the spores of moulds and yeasts are easily destroyed but bacterial spores are more resistant and if they survive the heat, processes may spoil the canned product. Only light processes are given to acid products, i.e. pH values lower than 4.5, such as canned fruits and preserves, because the spores of the majority of bacterial species are unable to develop in these acid products. For the non-acid foods like vegetables and soups, longer processes are required to destroy all spores. In order to determine adequate heat processes for destruction of the spores, it is necessary to know the resistance to heat in a liquid substrate of a known number of spores. At any temperature the time taken to destroy all of a given number of spores is known as the Thermal Death Time (T.D.T.). If supplied with the thermal death time data and the rate of penetration of heat into the can, it is possible to calculate an adequate heat process for the heat preservation of canned non-acid foodstuffs. However, not only is it necessary to destroy the spores of common spoilage types but also the spores of Clostridium botulinum which produces a toxin dangerous to man, and the development of this organism within the product would be a serious health hazard. Therefore, in determining adequate heat sterilising processes for canned foods, a kftowledge of the maximum heat resistance of spores of Cl. botulinum is of the utmost importance. A process for the absolute destruction of this organism is a minimum standard for all products with pH values greater than 4.5.

description: The CALICE collaboration has constructed highly granular electromagnetic and hadronic calorimeter prototypes to evaluate technologies for the use in detector systems at the future International Linear Collider. These calorimeters have been tested extensively in particle beams at CERN and at Fermilab. We present preliminary results of an analysis of hadronic events in the combined system under test at CERN in 2006 and 2007, comprising a SiW ECAL, a scintillator tile HCAL and a scintillator strip tail catcher, the latter two with SiPM readout. The properties of hadronic showers in the HCAL, compared to simulations performed with GEANT4, are discussed. Particular emphasis is placed on the study of the linearity of the detector response and on the single particle energy resolution achievable with simple weighting algorithms based on the local energy density in the hadronic showers.

description: Magnetic reconnection is a key process that drives the energy release in solar flares. This process can occur at multiple locations along the coronal loop. The reconnection generates energetic electrons capable of exciting wave modes and emissions as they propagate through the loop. In this follow-up study, we investigate the influence of the injection site location of these energetic electrons - either at the looptop (LT) or at the leg of the loop around a footpoint (FP) - on the excitation of wave modes especially the second harmonic emissions (X2) in coronal loops. Our simulations reveal that the injection location significantly impacts the spatial distribution and intensity of excited wave modes. When electrons are injected at the LT, electromagnetic X2, and Z modes dominate along the loop, with minimal excitation of Langmuir waves (Yousefzadeh et al. 2021; 2022). Conversely, the present study reveals that injection close to FP leads to a strong Langmuir wave excitation throughout the loop, particularly as electrons ascend toward the LT. We find that X2 and Z modes are consistently excited at the injection site with different intensities, regardless of the injection location. However, electron injection near the FP scenario creates favorable conditions for significant Langmuir wave generation, potentially leading to plasma emission under specific circumstances. These findings emphasize the importance of electron injection location in determining the properties of the excited and emitted waves in solar coronal loops.

description: Raman spectra and electrical conductance of individual, pristine, suspended, metallic single-walled carbon nanotubes are measured under applied gate potentials. The G- band is observed to downshift with small applied gate voltages, with the minima occurring at EF = +/- 1/2 Ephonon, contrary to adiabatic predictions. A subsequent upshift in the Raman frequency at higher gate voltages results in a 'W'-shaped Raman shift profile that agrees well with a non-adiabatic phonon renormalization model. This behavior constitutes the first experimental confirmation of the theoretically predicted breakdown of the Born-Oppenheimer approximation in individual single walled carbon nanotubes.

description: We present a detailed study of some $4q$ hadrons in quenched improved anisotropic lattice QCD. Using the $ππ$ and diquark-antidiquark local and smeared operators, we attempt to isolate the signal for $I(J^{P})=0(0^{+}), 2(0^{+})$ and $1(1^{+})$ states in two flavour QCD. In the chiral limit of light-quark mass region, the lowest scalar $4q$ state is found to have a mass, $m^{I=0}_{4q}=927(12)$ MeV, which is slightly lower than the experimentally observed $f_{0}(980)$. The results from our variational analysis do not indicate a signature of a tetraquark resonance in I=1 and I=2 channels. After the chiral extrapolation the lowest $1(1^{+})$ state is found to have a mass, $m^{I=1}_{4q}=1358(28)$ MeV. We analysed the static $4q$ potential extracted form a tetraquark Wilson loop and illustrated the behaviour of the $4q$ state as a bound state, unbinding at some critical diquark separation. From our analysis we conclude that scalar $4q$ system appears as a two-pion scattering state and that there is no spatially-localised $4q$ state in the light-quark mass region.

description: What is the impact of your library's work? How do you affect people's lives, and which tools can help you measure impact?

In a webinar on 21 May at 1400 CEST, hosted by LIBER, these questions were examined.

Julia Fallon of Europeana introduced the Impact Playbook: a step by step guide to measuring impact. Developed by cultural heritage and impact professionals, the Playbook guides you through the process of identifying the impact that your institution has, or is aiming to have. It provides a common approach that can be applied within any organisation.

We also heard from two libraries using the Impact Playbook in their daily work.

Marco de Niet of Leiden University Libraries (UBL) organised a workshop based on the Europeana Impact Playbook. As co-chair of the Europeana Impact Taskforce he wanted to introduce the Playbook to his colleagues in Leiden: to encourage them to use its tools to better understand the users’ perspectives and to look through their eyes at the digital services his colleagues were involved in.

In the webinar, Marco explained how he set up this workshop and gave an overview of the tools from the Playbook. By sharing his lessons learned, he hoped to encourage the organisation of similar workshops, thereby contributing to a shared understanding of impact with digital heritage collections.

A third speaker - Dr Dafydd Tudur, Head of Digital Access at the National Library of Wales (NLW) - also shared his experience with the Impact Playbook. The NLW was one of the first institutions to put the Playbook into practice and has since used it to measure the impact of a project based on the sharing of nearly 5.000 works from the Welsh National Portrait Collection on Wikicommons.

Four focus group meetings were held. The farmer participants included owner-operators, equity partners, sharemilkers and managers. Various rural professionals also attended. These meetings aimed to capture the participantsâ€™ interpretation on the advantages and disadvantages of various structures, and the issues driving change. Participantsâ€™ views on the ownership and management structures were influenced by the structures prevalent in each region, especially in the South Island where equity partnerships are prevalent.

Environmental signals from chemical measurements on Law Dome ice cores
Creators: name: Palmer, Anne Susan
Publisher: name: University Of Tasmania
Year: 2023

description: This study presents a 695-year record of the trace ion chemistry preserved in ice cores from the summit of Law Dome, East Antarctica. The record has seasonal resolution. The record was dated by counting the annual cycles in the oxygen isotope ratio. Ambiguous years were resolved by examination of the seasonality of the time-series of hydrogen peroxide, sodium, and non-sea-salt sulphate, as well as by comparison with other ice cores from the Law Dome region. This allowed unambiguous dating during the most recent period 1807-1995, with a maximum uncertainty of plus or minus 1 year at the beginning of the record in 1301. The time-series of sodium provides an excellent record of past storm activity in the Law Dome region. Extreme storm events appear as positive deviations from the mean annual cycle, which reaches maximum values in the winter months. The time-series also shows evidence for the chemical fractionation of sea-salt aerosol, with an average 60% depletion of sodium sulphate relative to sodium chloride. The depletion is greatest during the winter months. The nitrate time-series preserves evidence of short-duration high-energy solar events during the period 1840-1995 when instrumental records of solar events are available. This is also true for the period back to 1561 during which 68 solar events have been identified using the GISP2 Greenland ice-core. However, the Law Dome nitrate record does not preserve strong evidence of long-term solar variations such as the Schwabe (11-year), Hale (22-year) and Gleissberg (80-90 year) periodicities. The non-sea-salt sulphate record is sensitive to modulations in local marine biological productivity, with a large seasonal variation peaking in the austral summer. On longer time-scales the record is modulated by a combination of the natural variability of marine biota and the input of volcanic dust. Twenty-one volcanic events, characterised by elevated summer and winter sulphate levels for up to four years post-eruption, were identified. Volcanic sulphate from the Tambora eruption was reliably dated for the first time to reach Antarctica in the winter of 1816. Further study of the mean volcanic signature for 10 well-dated events gave an average stratospheric aerosol transport time of 1.5 years with a range of 0.6-2.6 years. Application of this estimate to the Kuwae volcanic signature gave an eruption date between 1455.9-1459.9, some three years after the date estimated from historical and tree-ring records.

description: We present a Chandra X-ray observation of the very high energy $γ$-ray source HESS$ $J1640-465. We identify a point source surrounded by a diffuse emission that fills the extended object previously detected by XMM Newton at the centroid of the HESS source, within the shell of the radio supernova remnant (SNR) G338.3-0.0. The morphology of the diffuse emission strongly resembles that of a pulsar wind nebula (PWN) and extends asymmetrically to the South-West of a point-source presented as a potential pulsar. The spectrum of the putative pulsar and compact nebula are well-characterized by an absorbed power-law model which, for a reasonable $N_{\rm H}$ value of $14\times 10^{22} \rm cm^{-2}$, exhibit an index of 1.1 and 2.5 respectively, typical of Vela-like PWNe. We demonstrate that, given the H$ $I absorption features observed along the line of sight, the SNR and the H$ $II surrounding region are probably connected and lie between 8 kpc and 13 kpc. The resulting age of the system is between 10 and 30 kyr. For a 10 kpc distance (also consistent with the X-ray absorption) the 2-10 keV X-ray luminosities of the putative pulsar and nebula are $L_{\rm PSR} \sim 1.3 \times 10^{33} d_{10 \rm kpc}^{2} \rm erg.s^{-1}$ and $L_{\rm PWN} \sim 3.9 \times 10^{33} d_{10}^{2} \rm erg.s^{-1}$ ($d_{10} = d / 10{\rm kpc}$). Both the flux ratio of $L_{\rm PWN}/L_{\rm PSR} \sim 3.4$ and the total luminosity of this system predict a pulsar spin-down power around $\dot{E} \sim 4 \times 10^{36} \rm erg s^{-1}$. We finally consider several reasons for the asymmetries observed in the PWN morphology and discuss the potential association with the HESS source in term of a time-dependent one-zone leptonic model.

The species may be differentiated from other members of the Astraptes fulgerator complex by the following combination of character states of the DNA barcode: 121 T; 123C; 298 T. All of these are unique states for A. augeas with respect to other members of the A. fulgerator complex. Holotype. Voucher 02-SRNP-23926, deposited at the University of Pennsylvania. Note: This species corresponds to the OTU ‘LOHAMP’ of Hebert et al. (2004). Etymology. The name augeas is a noun in apposition. In Greek mythology, Augeas of Elis was the owner of the stables that comprised Heracles’ Fifth Labour. The name recognizes the enormous throughput of the ACG barcoding endeavour and the resultant labour required of systematists.

description: Highly variable Black Hole X-ray Binary (BHXB) GRS~1915+105 has shown many flaring classes when the source oscillates between the High Soft state (HS) and the Hard Intermediate state (HIMS) with a transition time of less than 10 s. The X-ray flux is anti-correlated with hardness ratio (HR2) during these X-ray flaring classes. We have analyzed Astrosat/LAXPC \& SXT data and report here a new X-ray flaring class named $η$ class when the source oscillates between two HS states (the power-law index is always greater than 4) with transition time around 50 s. The X-ray flux is correlated with hardness ratio. This class is quasi-regular, and we have detected High Frequency Quasi Periodic Oscillations (HFQPOs) around 70 Hz during this new flaring class. The accretion rate changes by a factor of three over the burst cycle. We report here the results of our extensive study of spectral and timing characteristics of this new class.

description: We study the vector-vector interaction within the framework of the hidden gauge formalism for the sector with quantum numbers charm C=0 and strangeness S=0 in the region around 4000 MeV. We get five poles, three of which could be identified with the Y(3940), Z(3930) and X(4160). These poles appear with quantum numbers I=0 and $J^{PC}=0^{++},2^{++}$ and $2^{++}$, respectively, and can be considered as hadronic molecules made of $D^*\bar{D}^*$, $D_s^*\bar{D}^*_s$.

description: The objective of this study was to assess the economic and environmental sustainability of new drip irrigation and fertigation systems (applying the mineral nutrient solution with irrigation water through driplines) compared with conventional nitrogen application and irrigation systems under regional conditions in six European regions: Czech Republic, Denmark, Italy, Poland, Portugal and Slovakia. Focus is put on potatoes because the negative environmental effect in this crop is relatively high. This study indicates that the costs of applying drip irrigation and fertigation systems are relatively high compared with conventional gun irrigation systems. However, the yield simulations based on the field trials and local conditions have also indicated that the potential yield increase from drip irrigation and fertigation seems promising in many regions. Based on these findings it is clear that the implementation of new technology must be adapted to local conditions regarding field size, farm practice and climatic conditions.

description: The objective of this research is to evaluate impacts of moving to a less trade distorting commodity program. An optimal control stochastic simulation model is teamed with primary representative farm data and a whole farm simulation model to evaluate the impacts of shifting government payments from countercyclical payments (CCPs) to direct payments (DPs) on U.S. crop producers. The actual difference in total government expenditures can be sizable when switching from an uncertain payment dependent on prices that fluctuate to a fixed payment that is paid regardless of prevailing market conditions. Results indicate producers historically experiencing prices high enough to exclude them from receiving substantial CCPs require very little or no increase in DPs to make them as financially viable as before removal of the CCPs. Cotton and rice farms, historically receiving significant levels of CCPs, will require a larger cash outlay in the form of DPs to maintain financial viability.
