description: This paper assesses farmers’ perception and adaptation to climate change to enhance policy towards tackling the challenges climate change poses to the farmers in Ghana. With regards to farmers’ perception and methods of adaptation, majority of the farmers perceived increase in temperature and decrease in rainfall pattern. Farmers’ level of adaptation was found to be relatively high with majority of the farmers using changing planting dates, different crop varieties, soil conservation and water harvesting as the major adaptation measures to climate change impacts. However, access to water, high cost of adaptation, lack of information, lack of knowledge on adaptation, insecure property rights, insufficient access to inputs and lack of credits were identified as the major barriers to adaptation. The probit regression estimation results indicated that the probability of willingness to pay for climate change mitigation policies increases with age, years of education and ownership of farm land.
Doubly covariant action principle of singular hypersurfaces in general relativity and scalar-tensor theories

description: An action principle of singular hypersurfaces in general relativity and scalar-tensor type theories of gravity in the Einstein frame is presented without assuming any symmetry. The action principle is manifestly doubly covariant in the sense that coordinate systems on and off a hypersurface are disentangled and can be independently specified. It is shown that, including variation of the metric, the position of the hypersurface and matter fields, the variational principle gives the correct set of equations of motion: the Einstein equation off the hypersurface, Israel's junction condition in a doubly covariant form and equations of motion of matter fields including the scalar fields. The position of the hypersurface measured from one side of the hypersurface and that measured from another side can be independently variated as required by the double covariance.

description: Entropy games and matrix multiplication games have been recently introduced by Asarin et al. They model the situation in which one player (Despot) wishes to minimize the growth rate of a matrix product, whereas the other player (Tribune) wishes to maximize it. We develop an operator approach to entropy games. This allows us to show that entropy games can be cast as stochastic mean payoff games in which some action spaces are simplices and payments are given by a relative entropy (Kullback-Leibler divergence). In this way, we show that entropy games with a fixed number of states belonging to Despot can be solved in polynomial time. This approach also allows us to solve these games by a policy iteration algorithm, which we compare with the spectral simplex algorithm developed by Protasov.

description: This paper describes recent developments in sales markets of agricultural land in selected member states of the European Union and its candidate countries. Analysis focuses on the importance of the sales market for agricultural land, the average size of transacted plots, and the evolution and magnitude of the land sales prices. The share of agricultural land sold on the market is relatively stable in most of the old member states, with the exception of Finland, the Netherlands and the UK, where a more dynamic market is observed. For the new member states, the sales market for agricultural land is strongly affected by public sales under the ongoing land privatisation programmes, while strong variation prevails in the private sales market. Substantial differences are also observed in both the average size of the transacted plots and the sales prices. For the latter, price regulations partially explain the heterogeneity in the evolution of sales prices.

description: In this paper, we describe recent developments in the rental market for agricultural land in selected EU member states and candidate countries. The analysis focuses on the importance of the rental market as well as on the evolution of rental prices. It appears that the share of rented land in the total utilised agricultural area varies considerably among member states. In the old member states, the share of rented land ranges between 18% in Ireland and 74% in France, while in the new member states (NMS) it ranges from 17% in Romania to 89% in Slovakia. For the former, different strategies to provide tenure security to tenants can explain differences in the importance of rental markets. Changes in the significance of land rental have also reflected changes in institutions and in economic and political conditions. In the NMS, diverse approaches to land reform have resulted in assorted ownership structures and hence in differences in the share of rented land. Regarding rental prices, governments impose price restrictions on agricultural land rents in some countries, such that large divergences are observed in rental prices between and within member states.

description: Students often struggle when entering university and trying to learn from large-group lectures because the delivery, the expectations and the requirement for self-motivation in the learning process differs dramatically from that which is experienced in secondary education.This interactive, self-led resource aims to assist incoming Chemistry students with their transition to higher education, with a specific focus on learning from lectures. The research-led guide has been co-created by a Chemistry student (Drew Gupwell) and project supervisors (Linnea Soler & Smita Odedra), drawing on both facets of the learning and teaching experience.This e-resource contains practical advice for students on how to prepare for a lecture; how to take effective notes during a lecture; and guidance for post-lecture practices that promote deeper understanding of content. It contains student insights from the perspective of Drew, making it relatable to the student body through its authentic and honest reflections and encouragement.Watch this space - our research on the effectiveness of this resource will be published soon. Initial results indicate that it has had a positive impact on student learning and study habits.

description: All agricultural markets are subjected to institutional regulations that – in one way or another –affect the functioning of these markets, and this is no different for the agricultural land market in the EU. In this paper, we describe the existing regulations in the sales markets for agricultural land in selected EU member states and candidate countries. The analysis focuses on three types of sales market regulations and institutions: quantity regulations, price regulations and transaction costs. The differences in the regulatory framework between land acquisition and ownership by domestic and foreign investors are analysed, as well as the taxes associated with land sales and ownership, zoning regulations and market imperfections.

All-Multiplicity One-Loop Amplitudes in Born-Infeld Electrodynamics from Generalized Unitarity

description: We initiate a study of non-supersymmetric Born-Infeld electrodynamics in 4d at the quantum level. Explicit all-multiplicity expressions are calculated for the purely rational one-loop amplitudes in the self-dual ($++\ldots+$) and next-to-self-dual ($-+\ldots+$) helicity sectors. Using a supersymmetric decomposition, $d$-dimensional unitarity cuts of the integrand factorize into tree-amplitudes in a 4d model of Born-Infeld photons coupled to a massive complex scalar. The two-scalar tree-amplitudes needed to construct the Born-Infeld integrand are computed using two complimentary approaches: (1) as a double-copy of Yang-Mills coupled to a massive adjoint scalar with a dimensionally reduced form of Chiral Perturbation Theory, and (2) by imposing consistency with low-energy theorems under a reduction from 4d to 3d and T-duality. The Born-Infeld integrand is integrated in $d=4-2ε$ dimensions at order $\mathcal{O}(ε^0)$ using the dimension-shifting formalism. We comment on the implications for electromagnetic duality in quantum Born-Infeld theory.

One pion exchange and the quantum numbers of the Pc(4440) and Pc(4457) pentaquarks

description: The LHCb collaboration has recently discovered three pentaquark-like states --- the $P_c(4312)$, $P_c(4440)$ and $P_c(4457)$ --- close to the $\bar{D} Σ_c$ and the $\bar{D}^* Σ_c$ meson-baryon thresholds. The standard interpretation is that they are heavy antimeson-baryon molecules. Their quantum numbers have not been determined yet, which implies two possibilities for the $P_c(4440)$ and $P_c(4457)$: $J^P = \tfrac{1}{2}^{-}$ and $J^P = \tfrac{3}{2}^{-}$. The preferred interpretation within a contact-range effective field theory is that the $P_c(4440)$ is the $J^P = \tfrac{1}{2}^-$ molecule, while the $P_c(4457)$ is the $J^P = \tfrac{3}{2}^-$ one. Here we show that when the one pion exchange potential between the heavy-antimeson and heavy-baryon is taken into account, this conclusion changes, with the contrary identification being as likely as the original one. The identification is however cutoff dependent, which suggests that improvements of the present description (e.g. the inclusion of subleading order corrections, like two-pion exchanges) are necessary in order to disambiguate the spectroscopy of the molecular pentaquarks.

Quantum Simulation Logic, Oracles, and the Quantum Advantage

description: Query complexity is a common tool for comparing quantum and classical computation, and it has produced many examples of how quantum algorithms differ from classical ones. Here we investigate in detail the role that oracles play for the advantage of quantum algorithms. We do so by using a simulation framework, Quantum Simulation Logic (QSL), to construct oracles and algorithms that solve some problems with the same success probability and number of queries as the quantum algorithms. The framework can be simulated using only classical resources at a constant overhead as compared to the quantum resources used in quantum computation. Our results clarify the assumptions made and the conditions needed when using quantum oracles. Using the same assumptions on oracles within the simulation framework we show that for some specific algorithms, like the Deutsch-Jozsa and Simon's algorithms, there simply is no advantage in terms of query complexity. This does not detract from the fact that quantum query complexity provides examples of how a quantum computer can be expected to behave, which in turn has proved useful for finding new quantum algorithms outside of the oracle paradigm, where the most prominent example is Shor's algorithm for integer factorization.

description: In this paper, we describe the regulations governing the rental markets for agricultural land in selected EU member states and candidate countries. The analysis focuses on various kinds of regulations and institutions connected with the land rental market, including price, tenancy duration, quantity and other regulations, as well as transaction costs. The diverse government regulations on price restrictions and tenancy duration are analysed, along with the social norms observed for rental payments and contracts. The paper also examines the type and registration of contracts, the contract enforcement rules, the regulations on the inheritability of contracts and the pre-emptive right of tenants to buy the land.

description: We enumerate all possible types of spacetime causal structures that can appear in static, spherically symmetric configurations of a self-gravitating, real, nonlinear, minimally coupled scalar field ϕin general relativity, with an arbitrary potential V(ϕ), not necessarily positive-definite. It is shown that a variable scalar field adds nothing to the list of possible structures with a constant ϕfield, namely, Minkowski (or AdS), Schwarzschild, de Sitter and Schwarzschild - de Sitter. It follows, in particular, that, whatever is V(ϕ), this theory does not admit regular black holes with flat or AdS asymptotics. It is concluded that the only possible globally regular, asymptotically flat solutions are solitons with a regular center, without horizons and with at least partly negative potentials V(ϕ). Extension of the results to more general field models is discussed.

description: We investigate a technique to transform a linear two-parameter eigenvalue problem, into a nonlinear eigenvalue problem (NEP). The transformation stems from an elimination of one of the equations in the two-parameter eigenvalue problem, by considering it as a (standard) generalized eigenvalue problem. We characterize the equivalence between the original and the nonlinearized problem theoretically and show how to use the transformation computationally. Special cases of the transformation can be interpreted as a reversed companion linearization for polynomial eigenvalue problems, as well as a reversed (less known) linearization technique for certain algebraic eigenvalue problems with square-root terms. Moreover, by exploiting the structure of the NEP we present algorithm specializations for NEP methods, although the technique also allows general solution methods for NEPs to be directly applied. The nonlinearization is illustrated in examples and simulations, with focus on problems where the eliminated equation is of much smaller size than the other two-parameter eigenvalue equation. This situation arises naturally in domain decomposition techniques. A general error analysis is also carried out under the assumption that a backward stable eigenvalue solver method is used to solve the eliminated problem, leading to the conclusion that the error is benign in this situation.
On Fresnel Aether Drag, `Moving' Images, and Relativity

description: I show the decisive difference between genuine transverse Fresnel drag of light in a moving medium and the "spatial shift" measured with a time dependent interference pattern of light traversing a homogeneous finite medium (J. Leach et al., PRL 100, 153902 (2008)). In the latter case, the relative velocity and spatial shift are in fact zero and the `movement' is an elementary visual illusion, easily made superluminal. Three separate proofs are given for this fact. What is recorded in the experiment is just the difference between a time dependent space-fixed pattern and its time lagged version. This has no relevance to relative motion of any physical entity, Fresnel drag or relativity.

description: A detailed study of the transfer of ions in transfer capillaries of electrospray ion sources is presented. The laminar flow field for various capillary sizes and wall temperatures is calculated. It forms the base of ion transfer simulation of a large number of ions with space charge. This allows to study the thermodynamical conditions of the ions during transfer, which are found to vary strongly with the capillary dimensions. The dependence of mass flow and ion current on the size of the capillary is presented. Simple scaling relations are derived and tested. The method also allows to predict a transfer bias between different ion species depending on the difference in ion mobility and the composition of transferred ions.

description: The issue of identification of the parameter α0 in the price index of the Almost Ideal Demand System (AIDS) is examined. In nearly all empirical studies, the model’s likelihood function has been extremely flat in α0, and this parameter has not been able to be estimated. Assumed values are often used. In this paper, an AIDS-like model is developed with an easy- to-calculate chain-price index that replaces the price index in the original AIDS. The model stands by itself with respect to consumer demand theory and flexibility. An empirical analysis of beverage demands gives merit to the specification.

description: The proposal for a 64,000 hectare expansion of the Ord River Irrigation Area is one example of the renewed interest in agricultural development in the tropical north of the Australian continent. Thirty five years ago Bruce Davidson provided conclusive ‘evidence’ that agricultural development in this region was not financially sustainable unless supported by ongoing government subsidies. He argued that this conclusion was unlikely to change in the future. This paper outlines the controversy over past and proposed agricultural developments and explains the role of agriculture in the Kimberley economy today and in relation to other natural resource based industries. In a time when the paradigm of sustainable development recognises ‘quality of life’ and ‘equity’ as major objectives of development, positive benefitcost ratios are reduced to being a necessary but not the only sufficient factor in development decisions. The trend towards regional governance provides regional communities with both the opportunity for and difficult task of managing their natural resources sustainably into the future. The Ord-Bonaparte Program, a 5-year interdisciplinary multi-agency R&D program, is designed to support regional governance in the East Kimberley region. Its objectives are to provide relevant data and understanding, and build capacity particularly with indigenous stakeholders. Applied economic research, within an ecological economics framework, plays a critical role within the Program. The paper suggests a range of analytical methods and applications that would make significant contributions to the Program.

description: Consultation with industry identified a range of knowledge and information management tools required for building decision support systems (DSSs) that can help guide sustainable development of irrigated dairy production in the Murray Region. Individual production systems vary in complexity and input intensity and are coupled with the unique business and lifestyle goals of farm families. While single issue focussed decision support tools are limited to promoting understanding of single factor responses, the relevant opportunity costs for resources must be considered. Thus a whole farm perspective for DSSs is required to assist farm business managers optimise the profitability of production and development given the range of technical options, market conditions, environmental constraints, personal aspirations and family goals prevailing on that farm. The research, development and decision support needs elicited from producers using low, medium and high input production systems reflected both the necessity to optimise management of current systems and concerns regarding likely expansion paths for viable businesses.
POSSIBILITIES AND LIMITS TO THE LIBERALISATION OF INTERNATIONAL AGRICULTURAL TRADE IN THE WTO MILLENIUM ROUND (SPECIAL ATTENTION TO THE TRANSITORY ECONOMIES)

Year: 2000
Subjects: International Relations/Trade

description: Through the comprehensive regulation international agricultural trade, the GATT Uruguay Round was already a significant move towards the elimination of market distorting factors/barriers. But the Agreement of Agriculture was only the first step on this long path and at the same time certain internal contradictions were generated: Due to the “dirty tariffication” the heavy protectionist countries could still impose high import duties; The mechanism for limiting domestic subsidies has not proven to be efficient; Certain hidden subsidies- such as export loans – were not included in the liberalisation system etc. The new WTO Round starting at the end of 1999 offers again the chance to further reduce the market distorting barriers. However, the planned main areas of discussion on the agenda of the Round bear potential conflicts: With regards to “market access” the point of view urging further liberalisation needs the application of the “Swiss formula” and also the increase of preferential market access; Those accused with protectionism will obviously raise and turn to other – non-trade related areas (such as “European Agricultural model”, environmental protection, animal welfare etc.) to avoid the multilateral liberalisation of agricultural trade and the elimination of their domestic subsidies; Domestic subsidies shall be in the centre of attention and besides the questioning of “Blue box”, the re-definition of the “Green box” might occur. The paper analyses the main positions and possible impacts with concentrating on the principle actors (USA, EU, Cairn-group). Special attention is paid to the unique problems CEECs (transitory economies). The main conclusion of the presentation shall be that Millenium Round will probably be multiannual negotiation process, could lead to the further reduction of trade distorting factors despite the debates and compromises. Unfortunately, the comprehensive and complete multilateral liberalisation of the international agricultural markets – due to the conflicting interests of the main actors - multilateral liberalisation of international agricultural markets – is still not seen to be realistic,

description: The magnetotransport behaviour is investigated in detail across the first order magnetic phase transition from ferromagnetic to antiferromagnetic state in polycrystalline Ce(Fe$_{0.96}$Al$_{0.04}$)$_2$ sample. The study clearly brings out various generic features associated with a first order transition, viz., hysteresis, phase coexistence, supercooling and superheating, presence and limits of the metastable regimes. These results of magnetotransport study exhibit and support all the interesting thermomagnetic history effects that were observed in our earlier dc-magnetisation study on the same sample. Most notable here is the initial (or virgin) resistivity vs. field curve lying outside the hysteretic "butterfly shaped" magnetoresistivity loops obtained on cyclying the magnetic field between high enough positive and negative strengths. These findings, bearing one-to-one similarity with the data obtained in their magnetic counterpart (i.e., dc-magnetisation), have been ascribed an origin due to the arresting of this first order transition kinetics at low temperature and high magnetic field.

Possible evidence from laboratory measurements for a latitude and longitude dependence of G

description: Stability arguments suggest that the Kaluza-Klein (KK) internal scalar field, $Φ$, should be coupled to some external fields. An external bulk real scalar field, $ψ$, minimally coupled to gravity is proved to be satisfactory. At low temperature, the coupling of $ψ$ to the electromagnetic (EM) field allows $Φ$ to be much stronger coupled to the EM field than in the genuine five dimensional KK theory. It is shown that the coupling of $Φ$ to the geomagnetic field may explain the observed dispersion in laboratory measurements of the (effective) gravitational constant. The analysis takes into account the spatial variations of the geomagnetic field. Except the high PTB value, the predictions are found in good agreement with all of the experimental data.

Modification of classical electron transport due to collisions between electrons and fast ions

description: A Fokker-Planck model for the interaction of fast ions with the thermal electrons in a quasi-neutral plasma is developed. When the fast ion population has a net flux (i.e. the distribution of the fast ions is anisotropic in velocity space) the electron distribution function is significantly perturbed from Maxwellian by collisions with the fast ions, even if the fast ion density is orders of magnitude smaller than the electron density. The Fokker-Planck model is used to derive classical electron transport equations (a generalized Ohm's law and a heat flow equation) that include the effects of the electron-fast ion collisions. It is found that these collisions result in a current term in the transport equations which can be significant even when total current is zero. The new transport equations are analyzed in the context of a number of scenarios including $α$ particle heating in ICF and MIF plasmas and ion beam heating of dense plasmas.
Neural Network Models for Stock Selection Based on Fundamental Analysis

description: Application of neural network architectures for financial prediction has been actively studied in recent years. This paper presents a comparative study that investigates and compares feed-forward neural network (FNN) and adaptive neural fuzzy inference system (ANFIS) on stock prediction using fundamental financial ratios. The study is designed to evaluate the performance of each architecture based on the relative return of the selected portfolios with respect to the benchmark stock index. The results show that both architectures possess the ability to separate winners and losers from a sample universe of stocks, and the selected portfolios outperform the benchmark. Our study argues that FNN shows superior performance over ANFIS.

Electrical conductivity and Hall conductivity of hot and dense quark gluon plasma in a magnetic field: a quasi particle approach

description: We estimate here the electrical and Hall conductivity using a quasiparticle approach for quark matter. We use a Boltzmann kinetic approach in presence of external magnetic field. We confront the results of model calculations with Lattice QCD simulations for vanishing magnetic field. In general electrical conductivity decreases with magnetic field. The Hall conductivity on the other hand can show a non monotonic behaviour with magnetic field due to an intricate interplay of behaviour of relaxation time and strength of the magnetic field. We argue for vanishing quark chemical potential Hall conductivity vanishes and quark gluon plasma with finite quark chemical potential can show Hall effect. Both electrical conductivity and Hall conductivity increases with increasing quark chemical potential.

A spacetime ontology compatible with quantum mechanics

subject: FOS: Physical sciences

description: The ontology proposed in this paper is aimed at demonstrating that it is possible to understand the counter-intuitive predictions of quantum mechanics while still retaining much of the framework underlying classical physics, the implication being that it is better to avoid wandering into unnecessarily speculative realms without the support of conclusive evidence. In particular, it is argued that it is possible to interpret quantum mechanics as simply describing an external world consisting of familiar physical entities (e.g., particles or fields) residing in classical 3-dimensional space (not configuration space) with Lorentz covariance maintained.

description: Australian dairyfarmers are efficient by world standards and average farm production has expanded significantly in recent years. This has been achieved through increased use of land for grazing, better pasture and nutritional management, increased use of machinery, agricultural chemicals, and irrigation. Milk yields per cow have increased substantially. With the expansion of milk production, there has been increasing pressure on the environment surrounding dairyfarms. In addition, farms are often located in areas with aesthetic environments that are frequently visited by non-farming members of the community and farms may be located in catchments that feed water into storage areas for potable water supplies for urban areas. Dairy farms therefore rate highly in terms of environmental concern within the community. Life cycle analysis has been used extensively in Europe, the United States, and Japan for appraisal of industrial production systems and there has been a growing interest in recent years in the application of LCA for agricultural production to assess environmental impact and sustainability. This paper focuses on the conduct of a preliminary life cycle assessment of the milk production system used on dairy farms in south Queensland. Life Cycle Assessment methods are discussed and methodological issues associated with its application to agricultural production systems raised.
