description: Concerns about climate change and the general status of the environment have increased expectation that food products have sustainability credentials, and that these can be verified. There are significant and increasing pressures in key export markets for information on Greenhouse gas (GHG) intensity of products throughout its life-cycle. How this information is conveyed to consumers is a key issue. Labelling is a common method of communicating certain product attributes to consumers that may influence their choices. In a choice experiment concerning fruit purchase decisions, this study estimates willingness to pay for sustainability attributes by consumers in Japan and the UK. The role of label presentation format is investigated: text only, text and graphical, and graphical only. Results indicate that sustainability attributes influence consumers’ fruit purchase decisions. Reduction of carbon in fruit production is shown to be the least valued out of sustainability attributes considered. Differences are evident between presentation formats and between countries, with increased nutrient content being the most sensitive to format and country while carbon reduction is the most insensitive and almost always valued the least.

description: The ‘openness’ of farming systems that is the focus of this paper is ‘open to information’, in particular the way that new information from the farming systems research project, Dairy Directions, flows from research outputs to dairy farmers. Dairy Directions is a multidisciplinary research activity centred on a steering group of interested parties, mostly farmers, scientists and economists, but also drawing on extension agents, natural resource managers, water service providers, community service providers and public policy participants. The core general research question of Dairy Directions is ‘What options do farmers running different dairy farming systems have to achieve their goals in an uncertain future?’ The goals analysed by the project are predominantly economic and financial – maintaining or increasing profit and cash flow, growing wealth, managing risk, preparing for succession and balancing the dairy work-life balance. Their uncertain future encompasses variability in prices, as well as the natural environment and the policy setting.

description: We investigate a lattice of coupled logistic maps where, in addition to the usual diffusive coupling, an advection term parameterized by an asymmetry in the coupling is introduced. The advection term induces periodic behavior on a significant number of non-periodic solutions of the purely diffusive case. Our results are based on the characteristic exponents for such systems, namely the mean Lyapunov exponent and the co-moving Lyapunov exponent. In addition, we study how to deal with more complex phenomena in which the advective velocity may vary from site to site. In particular, we observe wave-like pulses to appear and disappear intermittently whenever the advection is spatially inhomogeneous.

description: Since the 1970s, there has been a broad shift from arm‘s length to long-term strategic alliance procurement practices across nations and industries. This has happened for sound commercial reasons. Peculiarities of agricultural production have slowed this shift in many food industry sectors, but it is now proceeding apace – driven primarily by rapidly globalising supermarket chains. In most Australian agri-food sectors, few firms have the scale or level of sophistication that would make them attractive strategic alliance partners either for international food retailers or for their category managers. The reasons for this include a combination of past government failures (inappropriate policies) and failures or inefficiencies in a range of information markets. The long-term nature of strategic alliances generates significant first-mover advantages for suppliers. Australian food producers risk being locked out of attractive opportunities if they fail to adapt to the new mode of contracting. For regional economies, the long-term benefits from accelerating strategic alliance adoption are likely to be large. Such benefits will flow on to many who are not usually considered private beneficiaries of that adoption. In other words, there are significant public benefits in prospect. While the results of past government intervention in this field have been mixed, there has been much learnt internationally from such experience. In Australia, many of the inappropriate policies have now been reversed and the prospects for cost-effective government assistance in the relevant information markets are good.

The aim of the research is to analyze the correlation of humanitarian, social and technological components in the methodology of teaching historical disciplines. The comparative method was chosen as a key method. The work uses the method of hypotheses, content analysis of the source base, and experience in studying University teaching practice. Identifying the prerequisites for “incorrect" interpretation of historical events, the author compares legal, forensic and philosophical approaches.
What fraction of stars formed in infrared galaxies at high redshift?

description: Star formation happens in two types of environment: ultraviolet-bright starbursts (like 30 Doradus and HII galaxies at low redshift and Lyman-break galaxies at high redshift) and infrared-bright dust-enshrouded regions (which may be moderately star-forming like Orion in the Galaxy or extreme like the core of Arp 220). In this work I will estimate how many of the stars in the local Universe formed in each type of environment, using observations of star-forming galaxies at all redshifts at different wavelengths and of the evolution of the field galaxy population.

Modelling Rural Land Use in New Zealand - A Discrete Choice Perspective

Year: 2011
Subjects: Land Economics/Use

description: The economic model I use to describe landowners’ land use decisions is a standard discrete choice random utility maximization model.1 Land is of heterogeneous quality, and suitability for the various uses depends on (multiple dimensions of) quality. Therefore, at any given time, potential benefits derived from each parcel vary by use. As economic conditions change, production technologies advance and the farmer accumulates human capital, the relative desirability of land use alternatives may change on any parcel. When the top-ranked alternative changes due to these forces, the farmer converts the parcel to a different use. The observed pattern of land use therefore represents a snapshot of outcomes from a dynamic process.

description: We study a magnitude-limited sample of 10 gamma-ray burst (GRB) host galaxies with known spectroscopic redshifts (0.43 < z < 2.04). From an analysis of the spectral energy distributions (SEDs), based on published broad-band optical and near-infrared photometry, we derive photometric redshifts, galaxy types, ages of the dominant stellar populations, internal extinctions, and ultraviolet (UV) star-formation rates (SFRs) of the host galaxies. The photometric redshifts are quite accurate despite the heterogeneous nature of the sample: The r.m.s. errors are sigma(z) = 0.21 and sigma(Delta z/(1+z_spec)) = 0.16 with no significant systematic offsets. All the host galaxies have SEDs similar to young starburst galaxies with moderate to low extinction. A comparison of specific SFRs with those of high-redshift galaxies in the Hubble Deep Fields shows that GRB hosts are most likely similar to the field galaxies with the largest specific SFRs. On the other hand, GRB hosts are not significantly younger than starburst field galaxies at similar redshifts, but are found to be younger than a sample of all types of field galaxies.

description: In recent times, there has been increasing demand in the Canterbury region of New Zealand for the abstraction of water from rivers. The impact of this demand has lead to unacceptable minimum river flows and has adversely affected river ecology. In an effort to resolve these issues dams have been constructed. To evaluate the impact of these dam projects on all river values, an ecosystem services approach is developed. This ecosystem services approach coupled with various evaluation methods are applied for the purposes of assessing the cost-effectiveness of the Opuha Dam and the sustainability of the Opihi river system now modified by the Opuha Dam. To evaluate the cost-effectiveness of this dam project cost utility analysis is applied through the development of an ecosystem services index (ESI). The index is constructed from the aggregation of normalized indicators that represent each ecosystem service and preferential weights of each ecosystem service. The evaluation of sustainability is considered both according to weak and strong criteria. Weak sustainability is evaluated by a non-declining ecosystem services index over time. Strong sustainability is evaluated by the thresholds or safe minimum standards where an ecosystem service, as represented by an indicator, should not pass below. Fifteen ecosystem services provided by the Opihi river were identified and data for forty-two indicators was compiled to assess the provision of these services pre- and post-dam. Fifteen regional and six local stakeholder representatives were interviewed to elicit preferential weights for each ecosystem service. Assessment of both the ESI and safe minimum standards indicates that since dam construction the river has progressed towards both weak and strong sustainability in its provision of ecosystem services. The cost-effectiveness of the dam however was poor. While further work remains to refine the approach, namely to develop more effective indicators of river ecosystem services, the work does present a novel method to evaluate the impacts of dams on river systems.

description: We show that subwavelength imaging by negative index materials (NIM), related to their "soft" electromagnetic response, is very (and non trivially) sensitive to the surface properties. A minute deviation of dielectric permittivity epsilon or magnetic permeability mu from the ideal values epsilon = mu = -1 in thin surface layer(s) results in drastic reduction of the resolution limit of a NIM slab. There may be a gap in the polariton spectrum and this would allow establishment of a stationary regime even without losses.

description: Policy makers in Vietnam face difficult choices when deciding reservoir water management strategies between irrigation and fisheries. In this paper, an economic optimization model for water management is developed to facilitate policy makers' decision making. The model includes the response of rice and fish yields to key factors including reservoir water levels, the timing and quantity of water release, and climatic conditions. The model accounts for variation in rainfall patterns, irrigation requirements, and the demand for low water levels during the fish harvest season. The model is applied to the Daton reservoir in the south of Vietnam to maximize profits in each of three production scenarios where the reservoir's water is used for: (1) only producing rice, (2) only producing fish, and (3) producing rice and fish. Key findings are: (1) for rice production, adequate water should be released to meet rice water requirement and residual water should be stored as a source of water in the case of low rainfall; (2) for fish production, maximum water should be released prior to the fish harvest; (3) for rice and fish production, although water should be released prior to fish harvest, sufficient residual water must remain to satisfy the water requirements of rice in its remaining stages of growth. The model could be applied to other multiple-use resources such as forests, river basins, and land.

description: As the biofuels are emerging as promising alternative transportation fuels across the world, they also offer huge potential for international trade in biofuels. A number of trade barriers such as import tariffs and domestic support have limited the scope for trade in biofuels. The purpose of this study is to analyze the implications of U.S. biofuel mandates, subsidies and import tariffs on global trade and welfare. We utilize the GTAP-BIO model, which was developed as a customized version of the Global Trade Analysis Project (GTAP) model capable of analyzing domestic and trade policy issues associated with biofuels (Birur, 2010). We supplement this model with updated and detailed sectoral level information on feedstock crops, different types of first and second generation biofuels and their byproducts. This highly refined data base facilitates the model for simulating changes in cropping patterns at individual crop level, land use changes, commodity prices, etc. We analyze the following policy scenarios in this study: (a) implementation of volume requirements consistent with the U.S RFS2 volumes for the year 2022 relative to a starting point of the base year 2004, (b) reduction in the ethanol specific import tariff from 54 ¢/gallon to 45 ¢/gallon, so that there will be “parity” between the U.S. and exporting country’s ethanol price, (c) Complete removal of the U.S. ethanol blenders’ credit and import tariff on ethanol, (d) combined implementation of (a) and (c) policy scenarios. This paper offers insights regarding the prospective policy options that can affect potential trade in biofuels amongst the major producing countries, such as the extent to which a removal of U.S. import tariff on ethanol affects pasture and forest land conversion in Brazil.

description: This study presents a thorough discussion of the efficiency and effectiveness improvement from optimization models (Binary Linear Programming and Goal Programming), as applied to the Department of Defense’s Readiness and Environmental Protection Initiative. The OM models can yield 21% and 19.1% higher benefit scores respectively, spending $13,013,473 and $31,463,473 less total acquisition costs. To achieve the same level of conservation benefits for the current rank based approach, the REPI would spend additional $20.1 million and approximate 50% of the budget. A counterpart of OM- the cost-effective analysis is observed to be inefficient when the problem becomes complex. In a real world of political environment of the conservation programs, we suggest a hybrid method of current rank based approach and the OM as well as the GP to address incompatible goals of interests groups.
Communicating emotion through a haptic link : a study of the influence of metaphor, personal space and relationship
Creators: name: Smith, Jocelyn Darlene
Publisher: name: University of British Columbia
Year: 2010

description: The world is more and more connected and yet we are often physically distant from people we care about. Technology increasingly supports remote interpersonal communication but has yet to integrate our sense of touch into this interaction. Researchers in the field of haptics (touch and technology) have started exploring computer-mediated touch interaction. The question is how should a computer-mediated person-to-person touch interaction be designed. In this thesis, we concentrate on how the design of a haptic interaction model influences performance and subjective experience of a dyad. Specifically, we examine the effect of using different metaphors to develop and explain the haptic interaction model, creating interaction models with and without a haptic display of personal space, and the type of relationship shared by the dyad using the device on ability to communicate emotion haptically. We also explore how dyads use these interactions to communicate emotion. We ran a structured study, in which participants communicated emotion with a haptic device and found that participants were able to communicate some emotional content through the haptic interactions. A significant effect of the interaction metaphor on performance was found. Participants preferred interactions with a haptic indicator of personal space, and participants' reported metaphor preferences depended on their relationship. Finally, we found that common actions were used to express each emotion, even though this is a new media unfamiliar to participants.

description: The abundance of satellite dwarf galaxies has long been considered a crucial test for the current model of cosmology leading to the well-known missing satellite problem. Recent advances in both simulations and observations have allowed to study dwarf galaxies around host galaxies in more detail. We have surveyed a 72 deg2 area of the nearby Sculptor group using the Dark Energy Camera - also encompassing the two low-mass Local Volume galaxies NGC24 and NGC45 residing behind the group - to search for hitherto undetected dwarf galaxies. Apart from the previously known dwarf galaxies we have found only two new candidates down to a 3 sigma surface brightness detection limit of 27.4 r mag arcsec-2. Both systems are in projection close to NGC24. However, one of these candidates could be an ultra-diffuse galaxy associated to a background galaxy. We compared the number of known dwarf galaxy candidates around NGC24, NGC45, and five other well-studied low-mass giant galaxies (NGC 1156, NGC2403, NGC5023, M33, and the LMC) with predictions from cosmological simulations and found that for the stellar-to-halo mass models considered, the observed satellite numbers tend to be on the lower end of the expected range. This could either mean that there is an over-prediction of luminous subhalos in LambdaCDM or - and more likely - that we are missing some of the satellite members due to observational biases.

Depending on the average growth velocity the model exhibits a non-equilibrium wetting transition which is characterized by an additional surface critical exponent theta. Simulating the single-step model in one spatial dimension we provide accurate numerical estimates for theta and investigate the distribution of contact points between the substrate and the interface as a function of time. Moreover, we study the influence of finite-size effects, in particular the time needed until a finite substrate is completely covered by the wetting layer for the first time.

description: In this paper, we consider optimizing a smooth, convex, lower semicontinuous function in Riemannian space with constraints. To solve the problem, we first convert it to a dual problem and then propose a general primal-dual algorithm to optimize the primal and dual variables iteratively. In each optimization iteration, we employ a proximal operator to search optimal solution in the primal space. We prove convergence of the proposed algorithm and show its non-asymptotic convergence rate. By utilizing the proposed primal-dual optimization technique, we propose a novel metric learning algorithm which learns an optimal feature transformation matrix in the Riemannian space of positive definite matrices. Preliminary experimental results on an optimal fund selection problem in fund of funds (FOF) management for quantitative investment showed its efficacy.

description: The climate change is global problems. It is predicted to have more severe impact on developing country which most of population are poor. The main impact of climate change on poverty is changing crop productivity and commodity prices. However, there are few studies on the relationship between climate change and poverty. Therefore, this study will use Laos which has a high share of agriculture sector on GDP and high poverty rates as a case study to assess the impact the climate change on national wide-economy and climate change using CGE model. The preliminary result shows that climate change has serious impact of Lao economy in term of declining GDP. On the other hand, the micro-simulation indicates that the impact on poverty was negligible. This is because the households in Laos are autarky and not affected by the changes of prices and wages due to climate change.

description: Complex scheduling problems require a large amount computation power and innovative solution methods. The objective of this paper is the conception and implementation of a multi-agent system that is applicable in various problem domains. Independent specialized agents handle small tasks, to reach a superordinate target. Effective coordination is therefore required to achieve productive cooperation. Role models and distributed artificial intelligence are employed to tackle the resulting challenges. We simulate a NP-hard scheduling problem to demonstrate the validity of our approach. In addition to the general agent based framework we propose new simulation-based optimization heuristics to given scheduling problems. Two of the described optimization algorithms are implemented using agents. This paper highlights the advantages of the agent-based approach, like the reduction in layout complexity, improved control of complicated systems, and extendability.

description: Adverse drug events (ADEs) are a serious health problem that can be life-threatening. While a lot of studies have been performed on detect correlation between a drug and an AE, limited studies have been conducted on personalized ADE risk prediction. Among treatment alternatives, avoiding the drug that has high likelihood of causing severe AE can help physicians to provide safer treatment to patients. Existing work on personalized ADE risk prediction uses the information obtained in the current medical visit. However, on the other hand, medical history reveals each patient's unique characteristics and comprehensive medical information. The goal of this study is to assess personalized ADE risks that a target drug may induce on a target patient, based on patient medical history recorded in claims codes, which provide information about diagnosis, drugs taken, related medical supplies besides billing information. We developed a HTNNR model (Hierarchical Time-aware Neural Network for ADE Risk) that capture characteristics of claim codes and their relationship. The empirical evaluation show that the proposed HTNNR model substantially outperforms the comparison methods, especially for rare drugs.

The Hamiltonian of the two-mode model takes the form of the one-axis-twisting Hamiltonian which is known to generate spin squeezing. More importantly, we show that the SOC provides a convenient control knob to adjust the spin nonlinearity responsible for spin squeezing. Specifically, the spin nonlinearity strength can be tuned to be comparable to the two-body density-density interaction, hence is much larger than the intrinsic spin-dependent interaction strength in conventional two-component BEC systems such as $^{87}$Rb and $^{23}$Na in the absence of the SOC. We confirm the spin squeezing by carrying out a fully beyond-mean-field numerical calculation using the truncated Wigner method. Additionally, the experimental implementation is also discussed.

description: The U.S. Federal Government implements environmental, biofuels and crop insurance programs that influence land use. They are not well-integrated in that cost savings from crop insurance subsidies are not acknowledged when screening land for retirement or when calculating the cost of land retirement programs. We identify and evaluate an optimal benefit index for enrollment in a land retirement program that includes a sub-index to rank land according to insurance subsidy savings. All else equal, land ranked higher in the Lorenz stochastic order should be retired first. Empirical analysis based on field level data will be provided.

description: This paper proposes an extension of Chaitin's halting probability Ωto a measurement operator in an infinite dimensional quantum system. Chaitin's Ωis defined as the probability that the universal self-delimiting Turing machine U halts, and plays a central role in the development of algorithmic information theory. In the theory, there are two equivalent ways to define the program-size complexity H(s) of a given finite binary string s. In the standard way, H(s) is defined as the length of the shortest input string for U to output s. In the other way, the so-called universal probability m is introduced first, and then H(s) is defined as -log_2 m(s) without reference to the concept of program-size. Mathematically, the statistics of outcomes in a quantum measurement are described by a positive operator-valued measure (POVM) in the most general setting. Based on the theory of computability structures on a Banach space developed by Pour-El and Richards, we extend the universal probability to an analogue of POVM in an infinite dimensional quantum system, called a universal semi-POVM. We also give another characterization of Chaitin's Ωnumbers by universal probabilities. Then, based on this characterization, we propose to define an extension of Ωas a sum of the POVM elements of a universal semi-POVM. The validity of this definition is discussed. In what follows, we introduce an operator version \hat{H}(s) of H(s) in a Hilbert space of infinite dimension using a universal semi-POVM, and study its properties.

description: We propose a simple SIR model in order to investigate the impact of various confinement strategies on a most virulent epidemic. Our approach is motivated by the current COVID-19 pandemic. The main hypothesis is the existence of two populations of susceptible persons, one which obeys confinement and for which the infection rate does not exceed 1, and a population which, being non confined for various imperatives, can be substantially more infective. The model, initially formulated as a differential system, is discretised following a specific procedure, the discrete system serving as an integrator for the differential one. Our model is calibrated so as to correspond to what is observed in the COVID-19 epidemic. Several conclusions can be reached, despite the very simple structure of our model. First, it is not possible to pinpoint the genesis of the epidemic by just analysing data from when the epidemic is in full swing. It may well turn out that the epidemic has reached a sizeable part of the world months before it became noticeable. Concerning the confinement scenarios, a universal feature of all our simulations is that relaxing the lockdown constraints leads to a rekindling of the epidemic. Thus we sought the conditions for the second epidemic peak to be lower than the first one. This is possible in all the scenarios considered (abrupt, progressive or stepwise exit) but typically a progressive exit can start earlier than an abrupt one. However, by the time the progressive exit is complete, the overall confinement times are not too different. From our results, the most promising strategy is that of a stepwise exit. And in fact its implementation could be quite feasible, with the major part of the population (minus the fragile groups) exiting simultaneously but obeying rigorous distancing constraints.

description: In order to meet humanitarian assistance programs, donor organizations like WFP need to procure food either locally or import it. Internal conflict may pose significant barriers to local and regional procurement programs like P4P. We develop a methodology to estimate the cost of conflict using a microeconomic setting. We examine the use of forward contracts to procure locally and derive a) what price should be paid to the suppliers, b) how should contracts be designed so that agents relinquish conflict and sign P4P contracts.

Query answering using views for XML

description: The problem of answering query using views is to find efficient methods of answering a query using a set of previously materialized views over the database, rather than accessing the database. As XML becomes the standard of data representation and exchange over the internet, the problem has recently drawn more attentions because of its relevance to a wide varieties of XML data management problems, there is a pressing needs to develop more techniques to solve it for XML data effectively and efficiently. We study a class of XPath queries and materialized views which may contain child, descendant axis and predicates. We first describe an algorithm to find the maximally-contained rewritings in the absence of database schema. We then present an efficient algorithm to search the maximally-contained rewriting under choice-free acyclic schema and prove the uniqueness of the maximally-contained rewriting. Finally we show its performance experimentally by extending our algorithm to answer queries in XQuery expression.

description: Accurate and fast 3D object detection from point clouds is a key task in autonomous driving. Existing one-stage 3D object detection methods can achieve real-time performance, however, they are dominated by anchor-based detectors which are inefficient and require additional post-processing. In this paper, we eliminate anchors and model an object as a single point--the center point of its bounding box. Based on the center point, we propose an anchor-free CenterNet3D network that performs 3D object detection without anchors. Our CenterNet3D uses keypoint estimation to find center points and directly regresses 3D bounding boxes. However, because inherent sparsity of point clouds, 3D object center points are likely to be in empty space which makes it difficult to estimate accurate boundaries. To solve this issue, we propose an extra corner attention module to enforce the CNN backbone to pay more attention to object boundaries. Besides, considering that one-stage detectors suffer from the discordance between the predicted bounding boxes and corresponding classification confidences, we develop an efficient keypoint-sensitive warping operation to align the confidences to the predicted bounding boxes. Our proposed CenterNet3D is non-maximum suppression free which makes it more efficient and simpler. We evaluate CenterNet3D on the widely used KITTI dataset and more challenging nuScenes dataset. Our method outperforms all state-of-the-art anchor-based one-stage methods and has comparable performance to two-stage methods as well. It has an inference speed of 20 FPS and achieves the best speed and accuracy trade-off. Our source code will be released at https://github.com/wangguojun2018/CenterNet3d.
