description: This study aims to show how Australian households perceive climate change and what they are prepared to do to reduce the harmful effects of climate change. A web-based survey in November 2008 asked approximately 600 New South Wales households about their willingness to pay additional household expenses caused by the Carbon Pollution Reduction Scheme (CPRS) proposed by the Australian government. The Contingent Valuation Method (CVM), a widely used non-market valuation technique, was applied. Results of the study show there is a positive demand to mitigate climate change in Australia resulting from a wish to avoid climate change. Households’ willingness to pay (WTP) for climate change was, however, significantly curbed as households was uncertain about the extent of climate change and whether climate change policies are effective. Australian household support for the CPRS is influenced by schemes of other major greenhouse gas emitting countries (global co-operation). Only when people who didn’t answer the survey are assumed to value climate change mitigation the same as people who did answer the survey, do the benefits of the CPRS, as estimated by respondents’ WTP, exceed its costs.

description: The involvement of uncertainty of varying degrees when the total of the membership degree exceeds one or less than one, then the newer mathematical paradigm shift, Fuzzy Theory proves appropriate. For the past two or more decades, Fuzzy Theory has become the potent tool to study and analyze uncertainty involved in all problems. But, many real-world problems also abound with the concept of indeterminacy. In this book, the new, powerful tool of neutrosophy that deals with indeterminacy is utilized. Innovative neutrosophic models are described. The theory of neutrosophic graphs is introduced and applied to fuzzy and neutrosophic models. This book is organized into four chapters. In Chapter One we introduce some of the basic neutrosophic algebraic structures essential for the further development of the other chapters. Chapter Two recalls basic graph theory definitions and results which has interested us and for which we give the neutrosophic analogues. In this chapter we give the application of graphs in fuzzy models. An entire section is devoted for this purpose. Chapter Three introduces many new neutrosophic concepts in graphs and applies it to the case of neutrosophic cognitive maps and neutrosophic relational maps. The last section of this chapter clearly illustrates how the neutrosophic graphs are utilized in the neutrosophic models. The final chapter gives some problems about neutrosophic graphs which will make one understand this new subject.

description: To elicit household willingness to pay (WTP) for improvements in environmental quality in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean), a choice modelling (CM) study was conducted. This report presents results of research designed to investigate variations in WTP across different communities. The communities included local residents, distant/urban and distant/rural residents. Nine split samples were established to test for ‘location effects’. The analysis involved both conditional logit and random-parameters logit models. Natural resource management (NRM), including Catchment Management Authorities (CMAs), can use the non-market values obtained from this study to guide their investment decisions.
Pairing in magic-angle twisted bilayer graphene: role of phonon and plasmon umklapp

description: Identifying the microscopic mechanism for superconductivity in magic-angle twisted bilayer graphene (MATBG) is an outstanding open problem. While MATBG exhibits a rich phase-diagram, driven partly by the strong interactions relative to the electronic bandwidth, its single-particle properties are unique and likely play an important role in some of the phenomenological complexity. Some of the salient features include an electronic bandwidth smaller than the characteristic phonon bandwidth and a non-trivial structure of the underlying Bloch wavefunctions. We perform a theoretical study of the cooperative effects due to phonons and plasmons on pairing in order to disentangle the distinct role played by these modes on superconductivity. We consider a variant of MATBG with an enlarged number of fermion flavors, $N \gg 1$, where the study of pairing instabilities reduces to the conventional (weak-coupling) Eliashberg framework. In particular, we show that certain umklapp processes involving mini-optical phonon modes, which arise physically as a result of the folding of the original acoustic branch of graphene due to the moiré superlattice structure, contribute significantly towards enhancing pairing. We also investigate the role played by the dynamics of the screened Coulomb interaction on pairing, which leads to an enhancement in a narrow window of fillings, and study the effect of external screening due to a metallic gate on superconductivity. At strong coupling the dynamical pairing interaction leaves a spectral mark in the single particle tunneling density of states. We thus predict such features will appear at specific frequencies of the umklapp phonons corresponding to the sound velocity of graphene times an integer multiple of the Brillouin zone size.

description: Hypoxia has a significant impact on many physiological and pathological processes. Over the recent years, its role in modulation of epigenetic remodelling has also become clearer. In cancer, low oxygen environments and aberrant epigenomes often go hand in hand, and changes in DNA methylation are now commonly recognised as potential outcome indicators. TET (ten-eleven translocation) family enzymes are alpha-ketoglutarate-, iron- and oxygen-dependent DNA demethylases and are key players in these processes. Although TETs have historically been considered tumour suppressors, recent studies suggest that their functions in cancer might not be straightforward. Recently, inhibition of TETs has been reported to have positive impact in cancer immunotherapy and vaccination studies. This underlines the current interest in developing targeted pharmaceutical inhibitors of these enzymes. Here, we will survey the complexity of TET roles in cancer, and its hypoxic modulation, as well as highlight the potential of these enzymes as therapeutic targets.

description: We study direct-sum decompositions of torsion-free, finitely generated modules over a (commutative) Bass ring $R$ through the factorization theory of the corresponding monoid $T(R)$. Results of Levy-Wiegand and Levy-Odenthal together with a study of the local case yield an explicit description of $T(R)$. The monoid is typically neither factorial nor cancellative. Nevertheless, we construct a transfer homomorphism to a monoid of graph agglomerations--a natural class of monoids serving as combinatorial models for the factorization theory of $T(R)$. As a consequence, the monoid $T(R)$ is transfer Krull of finite type and several finiteness results on arithmetical invariants apply. We also establish results on the elasticity of $T(R)$ and characterize when $T(R)$ is half-factorial. (Factoriality, that is, torsion-free Krull-Remak-Schmidt-Azumaya, is characterized by a theorem of Levy-Odenthal.) The monoids of graph agglomerations introduced here are also of independent interest.

description: Interactive recommendation aims to learn from dynamic interactions between items and users to achieve responsiveness and accuracy. Reinforcement learning is inherently advantageous for coping with dynamic environments and thus has attracted increasing attention in interactive recommendation research. Inspired by knowledge-aware recommendation, we proposed Knowledge-Guided deep Reinforcement learning (KGRL) to harness the advantages of both reinforcement learning and knowledge graphs for interactive recommendation. This model is implemented upon the actor-critic network framework. It maintains a local knowledge network to guide decision-making and employs the attention mechanism to capture long-term semantics between items. We have conducted comprehensive experiments in a simulated online environment with six public real-world datasets and demonstrated the superiority of our model over several state-of-the-art methods.
Energy expenditure during breeding competition between feral Chinook salmon (Oncorphynchus tshawytscha) and native Atlantic salmon (Salmo salar)
Creators: name: Lobsinger, Charlene
Publisher: name: University of British Columbia
Year: 2009

description: The introduction of non-native species to many parts of the world is increasing and continues to be a major concern amongst scientists. My objective was to examine competition for space and other resources between native and introduced salmonids. Through physiological telemetry and behavioural observation, the movements, energy expenditure, and interactions within and between spawning feral Chinook salmon and released native Atlantic salmon were measured in Bronte Creek, a tributary of Lake Ontario. By combining telemetry and visual observations, the frequency, duration, and energy cost of all behaviours (including routine behaviours) were determined. The data were used to construct an energy budget for each species, to identify additional energy costs due to interspecific interactions, and the degree to which the added cost may influence reproductive success for both species. Chinook salmon were observed to be dominant to Atlantic salmon on the spawning grounds and had the highest average daily energy expenditure, 7090 cal/kg/day. Atlantic salmon spent most of their time hiding under rocks or holding in areas where Chinook salmon were not present and females had an average daily energy expenditure of 2703 cal/kg/day. Male Atlantic salmon consumed more energy on average per day than did female Atlantic salmon, 3771 cal/kg/day. However, Atlantic salmon remained on the spawning grounds for a greater amount of time and so were observed to conserve energy. If the frequency of interactive behaviours between the species were to increase then spawning may be compromised in that less energy may then be available for reproductive success. Neither of the species were seen to spawn in this study. This may be related to the additional energy costs of interspecific competition or to the presence of an introduced species on the spawning grounds of a native fish species. Results of this study may also be applicable to potential interactions between native Chinook salmon and farmed Atlantic salmon in British Columbia.

description: We develop an ab initio method to simulate the infrared vibrational response of metallic systems in the framework of time-dependent density functional perturbation theory. By introducing a generalized frequency-dependent Born effective charge tensor, we show that phonon peaks in the reflectivity of metals can be always described by a Fano function, whose shape is determined by the complex nature of the frequency-dependent effective charges and electronic dielectric tensor. The IR vibrational properties of graphite, chosen as a representative test case to benchmark our method, are found to be accurately reproduced. Our approach offers a first-principle scheme for the prediction and understanding of IR reflectance spectra of metals, that may represent one of the few available tools of investigation of these materials when subjected to extremely high-pressure conditions.

description: The article’s aim is to conduct a comparative cross-section analysis of the innovative behaviour of the German manufacturing industry. The peculiarities of the food industry are tested in a combined analysis based on both input and output indicators. Linear and logistic regressions are used to investigate the differences between the food industry and other branches of the manufacturing industry. In comparison to other branches, the food industry has lower research & development (R&D) expenditures whereas the import of research from more technology intensive sectors is high. Most of the released new products are improvements and imitations. Market novelties are rare. The development time for new products is relatively short compared to other industries, on average 8.5 months. A major part of innovations are imitated rapidly by competing firms, therefore the first mover advantages are low. Due to the low newness of innovations, marketing activities (e.g. advertising, labelling) are more important for new product introductions than in other industries. The regression analysis for the input indicators measured by the innovation intensity shows that the innovative behaviour of food companies significantly deviates from other manufacturing sectors. However, the logistic regression analysis of the output indicators doesn’t confirm these results. The dummy variable of the food companies has no significant impact on the output indicators. Firms in the food industry might embark on imitation and product modification strategies. Therefore, they realize an average innovation output without spending the same amount of money as the other industries. In addition, it can be confirmed that small enterprises of the German manufacturing industry have a higher innovation activity in terms of both innovation input and output. The impact of business expectations on input and output indicators is significantly positive. An international orientation measured by the ratio of exports to firm sales leads to a higher probability of introducing new products and novelties.

description: We report on orbital modulation of the 100-600 MeV gamma-ray emission of the $P_{\rm B}=4.6$ hr millisecond pulsar binary PSR J2339$-$0533 using 11 yr of Fermi Large Area Telescope data. The modulation has high significance (chance probability $p\approx 10^{-7}$), is approximately sinusoidal, peaks near pulsar superior conjunction, and is detected only in the low-energy 100-600 MeV band. The modulation is confined to the on-pulse interval, suggesting that the variation is in the 2.9-ms pulsed signal itself. This contrasts with the few other known systems exhibiting GeV orbital modulations, as these are unpulsed and generally associated with beamed emission from an intrabinary shock. The origin of the modulated pulsed signal is not yet clear, although we describe several scenarios, including Compton upscattering of photons from the heated companion. This would require high coherence in the striped pulsar wind.

description: The lightness of the Standard Model (SM) neutrinos could be understood if their masses were to be generated by new physics at a high scale, through the so-called seesaw mechanism involving heavy fermion singlets. If new physics violates baryon minus lepton number by only a small amount, the heavy fermion singlets as well as the SM neutrinos split into pairs of quasi-Dirac states. At the scale of the fermion singlets, this quasi-Diracness allows to enhance CP violation in their decays and the cosmic matter-antimatter asymmetry can be successfully generated through resonant leptogenesis. At lower scale, this quasi-Diracness results in small SM neutrino mass splitting which can be probed in oscillation experiments. Remarkably, the parameter space for viable leptogenesis spans over the regime relevant for solar and atmospheric neutrino oscillations.

description: Because consumers’ preferences are relevant determinants in the purchase decision, their measurement seems to be extremely important. Therefore, the article presents selected results of preference measurement (conjoint-analysis) with special regard to different food production modes (organic production, conventional production and production reflecting animal welfare aspects) and labelling of food origin (out of the region, from farm-gate and without labelling of the food origin). The empirical research shows surprising results: the organic produce is not as strongly preferred as the product alternative reflecting the animal welfare aspect. As a consequence, marketing-strategies should pay much more attention to animal welfare aspects, whereas organic production seems to be a less persuasive promotion argument. The contribution ends with implications for further research.

description: As agricultural policy reform and its effects have become increasingly territorialised, analyses which attempt to explain or predict impacts need to be more localised but also identify spillover effects. In addition to the predictions of policy shocks predicted by sectoral partial equilibrium models, local and regional general equilibrium approaches which establish the wider effects of such policy shocks have become popular. However, these neglect a major, underexplored difficulty: agriculture is usually described as a single sector in input-output accounts, whereas policy shocks with differential impacts have effects on other industries which are different to those implied by average input-output coefficients. Regionalisation of aggregated input-output tables adds further to these difficulties. The objective of this paper is to develop a relatively simple method for dealing with these problems. It establishes the theoretical basis for aggregation bias and shows how it can be measured, in two contrasting case study regions in the United Kingdom and Sweden. Having established that this is a significant problem, a simple but effective procedure is demonstrated, based on additional information on variable costs, which transforms policy shocks from a direct change in agricultural output to that transmitted to the suppliers of inputs. This method provides an impact close to that which could be calculated if the general equilibrium system had indeed been disaggregated, and supports use of this approach in impact studies where the researcher does not have the time or funding available for completely disaggregating the agricultural sector’s regional accounts.

description: We use a nonparametric estimation of the production function to investigate the relationship between farm productivity and farming scale in poor smallholder agricultural systems in the north of Burundi. Burundi is one of the poorest countries in the world, with a predominant small scale subsistence farming sector. A Kernel regression is used on data of mixed cropping systems to study the determinants of production including different factors that have been identified in literature as missing variables in the testing of the inverse relationship such as soil quality, location and household heterogeneity. Household data on farm activities and crop production was gathered among 640 households in 2007 in two Northern provinces of Burundi. Four production models were specified each with different control variables. For the relatively small farms, we find clear evidence of an inverse relationship. The relatively large farms show a different pattern. Returns to scale are found to be farm scale dependent. Parametric Cobb-Douglass models tend to over-simplify the debate on returns to scale because of not accounting for the different effects of large farms. Other factors that significantly positively affect production include the soil quality and production orientation towards banana or cash crop production. Production seems to be negatively affected by field fragmentation.

The work on the development of the evaluation of the impact of rural support is only in progress, the range of data sources is not large either. Therefore the author offers a solution how the evaluation of the RDP is organized in Latvia, with the resources and the amount of information available, and what activities are planned in the future. Special attention is devoted to the development of the methodology for calculating the direct economic effect, including the principles of the formation of the group of the affected farms and the control group, as well as the choice of the range of indicators for the analysis of measures. The approached mentioned in the research has already been applied when writing the Mid-term evaluation report.

description: Millimeter-wave (mmWave) multiple-input multiple-out (MIMO) systems relying on lens antenna arrays are capable of achieving a high antenna-gain at a considerably reduced number of radio frequency (RF) chains via beam selection. However, the traditional beam selection network suffers from significant performance loss in wideband systems due to the effect of beam squint. In this paper, we propose a phase shifter-aided beam selection network, which enables a single RF chain to support multiple focused-energy beams, for mitigating the beam squint in wideband mmWave MIMO systems. Based on this architecture, we additionally design an efficient transmit precoder (TPC) for maximizing the achievable sum-rate, which is composed of beam selection and beamspace precoding. Specifically, we decouple the design problems of beamspace precoding and beam selection by exploiting the fact that the beam selection matrix has a limited number of candidates. For the beamspace precoding design, we propose a successive interference cancellation (SIC)-based method, which decomposes the associated optimization problem into a series of subproblems and solves them successively. For the beam selection design, we propose an energy-max beam selection method for avoiding the high complexity of exhaustive search, and derive the number of required beams for striking an attractive trade-off between the hardware cost and system performance. Our simulation results show that the proposed beamspace precoding and beam selection methods achieve both a higher sum-rate and a higher energy efficiency than its conventional counterparts.

description: Current considerations for the post-2013 CAP create the need for the investigation and evaluation of alternative CAP scenarios and their effects on agriculture, environment and regional development in EU rural areas. To this end, a system-dynamics model is developed and utilized to evaluate the impacts of alternative CAP scenarios in a Greek rural area (prefecture of Trikala). This particular model features four basic subsystems (agriculture, environment, regional economy and human resources) specified and analyzed through a linear programming model, a dynamic input-output model and an age-cohort demographic model, respectively. Four alternative policy scenarios are specified, dealing with possible developments on Pillars 1 and 2. Model simulations produce scenario-specific effects for the 2007-2013 period, and up to 2020 in the form of changes in land use and farm output, environmental indicators associated with farm activity, economy-wide impacts and impacts on local population. Results show that different future orientations for the CAP are associated with different impacts on agricultural activity, the environment and total economic activity in this area. A reduction of Pillar 1 funds and a dedication of Pillar 2 spending on Axis 2 generate negative effects on local agriculture, but benefit the local environment and economy-wide incomes. On the other hand, a more “productive” orientation of Pillar 2 positively affects local employment (compared to the current CAP) but does not create any positive or negative effects on the environment of this region

description: The paper starts from the critiques to the Barro-style methodology for convergence analysis with the aim of reviewing the econometric approaches for testing spatial effects in convergence process related to both cross sectional and panel data regressions, a framework that is applied to a sample of 80 regions of the EU-15 at NUTS-2 level over the time period from 1980 to 2007. The empirical analysis compares results from approaches and, at the same time, provides empirical evidence from techniques that are now widely recognised in the understanding of regional growth and the influence of space but never or rarely applied to the agricultural context. Results point out the complexity of the process of agricultural regional convergence in Europe that cannot be adequately captured by the non-spatial growth regression models that have dominated the research and policy debate in this field. Evidence for convergence and spatial dependence emerges especially when estimations refers to spatial panel models while the effects of spatial heterogeneity and the existence of convergence clubs come out from the geographically weighted regression approach. The paper represents a point of departure for further researches in this field whose most important directions are underlined.

description: The Helpdesk of European Evaluation Network for Rural Development supported by a group of external experts has prepared a Working Paper on ”Capturing the impacts of Leader and measures to improve the Quality of life (QoL) in rural areas”. The working paper provides methodological support for evaluators, managing authorities and other interested parties. The main evaluation challenges include: assessing the “double scope” of Leader (it is both a process and generates impacts); the need to adequately define what is QoL in the context of Rural Development Programmes (RDPs); tackling the qualitative nature of the effects; identifying contributions from small-scale interventions; and the fact that the EU’s Common Monitoring and Evaluation Framework (CMEF) requires assessment of impacts ultimately at programme level. The working paper is targeted primarily at practitioners involved in the evaluation of the current RDPs (2007-2013). It proposes a framework of reference which provides a conceptual model in order to assess Quality of Life around four dimensions – environment, socio-culture, economy and governance.
High temperature superconductivity due to the long-range electron-phonon interaction, application to isotope effects, thermomagnetic transport and nanoscale heterogeneity in cuprates

description: Strong electron-phonon interactions in cuprates and other high-temperature superconductors have gathered support over the last decade in a large number of experiments. Here I briefly introduce the Froehlich-Coulomb multi-polaron model of high-temperature superconductivity, which includes strong on-site repulsive correlations and the long-range Coulomb and electron-phonon (e-ph) interactions. Our extension of the BCS theory to the strong-coupling regime with the long-range \emph{unscreened} electron-phonon interaction could naturally explain the isotope effects, unconventional thermomagnetic transport, and checkerboard modulations of the tunnelling density of states in cuprates.

description: Horticultural firms are dependent on energy to produce, while policy makers focus on reducing the use of energy and investment in energy-saving technologies. The paper aimed to asses Dutch greenhouse farmers‘ responses to policies that would affect prices of different energy inputs. The farmer’s behaviour is modelled in two steps: firms are assumed to maximize profit at given energy use level, and firms are assumed to minimize the discounted sum of energy costs. The model is estimated using farm survey data spanning the period 2001-2008. Short-run and long-run elasticities with respect to prices and investments in energy-using technology are estimated. The greenhouse sector shows a fast adjustment of energy capital towards its long-run equilibrium. This model provides a framework for assessing policy simulations. Policies will not have much more impact in the long-run compared to the short-run, and incentives to invest would result in an increase of the use of energy-saving technologies

description: A local gauge invariant interaction Lagrangian for two gauge fields of spin $\ell$ and $\ell-2$ $(\ell>2)$ and the scalar field is defined. It gives rise to one-loop corrections to the gauge field propagator. The loop function contains the Goldstone boson propagator for gauge symmetry breaking. The proportionality factor in front of this propagator is the mass squared of the gauge boson.

description: Observations of gamma ray bursts (GRB) afterglows in different spectral bands provide a most valuable information about their nature, as well as about properties of surrounding medium. Powerful infrared afterglow was observed from the strong GRB041219. Here we explain the observed IR afterglow in the model of a dust reradiation of the main GRB signal in the envelope surrounding the GRB source. In this model we do not expect appearance of the prompt optical emission which should be absorbed in the dust envelope. We estimate the collimation angle of the gamma ray emission, and obtain restrictions on the redshift (distance to GRB source), by fitting the model parameters to the observational data.
