description: This paper argues that recent increases in international food prices worsened poverty incidence in Indonesia, even though many poor farmers benefited. This conclusion is based on the application of a multi-sectoral, multi-household general equilibrium model of the Indonesian economy. The positive effect on the welfare of poor farmers was exceeded by the negative effect on poor consumers. Indonesia’s ban on rice imports since 2004 complicates this account. The import ban shielded Indonesia’s internal rice market from the temporary world price increases from 2007 to 2008, but did so at the expense of permanently increasing both rice prices and poverty incidence.
A robust numerical method to study oscillatory instability of gap solitary waves

description: The spectral problem associated with the linearization about solitary waves of spinor systems or optical coupled mode equations supporting gap solitons is formulated in terms of the Evans function, a complex analytic function whose zeros correspond to eigenvalues. These problems may exhibit oscillatory instabilities where eigenvalues detach from the edges of the continuous spectrum, so called edge bifurcations. A numerical framework, based on a fast robust shooting algorithm using exterior algebra is described. The complete algorithm is robust in the sense that it does not produce spurious unstable eigenvalues. The algorithm allows to locate exactly where the unstable discrete eigenvalues detach from the continuous spectrum. Moreover, the algorithm allows for stable shooting along multi-dimensional stable and unstable manifolds. The method is illustrated by computing the stability and instability of gap solitary waves of a coupled mode model.

description: Profit maximization (PM) is to select a subset of users as seeds for viral marketing in online social networks, which balances between the cost and the profit from influence spread. We extend PM to that under the general marketing strategy, and form continuous profit maximization (CPM-MS) problem, whose domain is on integer lattices. The objective function of our CPM-MS is dr-submodular, but non-monotone. It is a typical case of unconstrained dr-submodular maximization (UDSM) problem, and take it as a starting point, we study UDSM systematically in this paper, which is very different from those existing researcher. First, we introduce the lattice-based double greedy algorithm, which can obtain a constant approximation guarantee. However, there is a strict and unrealistic condition that requiring the objective value is non-negative on the whole domain, or else no theoretical bounds. Thus, we propose a technique, called lattice-based iterative pruning. It can shrink the search space effectively, thereby greatly increasing the possibility of satisfying the non-negative objective function on this smaller domain without losing approximation ratio. Then, to overcome the difficulty to estimate the objective value of CPM-MS, we adopt reverse sampling strategies, and combine it with lattice-based double greedy, including pruning, without losing its performance but reducing its running time. The entire process can be considered as a general framework to solve the UDSM problem, especially for applying to social networks. Finally, we conduct experiments on several real datasets to evaluate the effectiveness and efficiency of our proposed algorithms.

A script theory of intentional content
Creators: name: Guirguis, Mazen Maurice
Publisher: name: University of British Columbia
Year: 2009

description: Fred Dretske (1981) claimed that the essence of the kind of cognitive activity that gives rise to Intentional mental states is a process by which the analogue information coming from a source-object is transformed into digital form. It is this analogue-to-digital conversion of data that enables us to form concepts of things. But this achievement comes with a cost, since the conversion must involve a loss of information. The price we pay for the lost information is a proportional diminishment in our ability to discriminate the source-object from others that may be similar to it. I argue that this fact underlies an important distinction between what a mental state may be about and to what the state may be directed, Aboutness and directedness are two of four Intentional dimensions on which this project concentrates. The other two are aspectual shape and misrepresentation. The distinction between aboutness and directedness is a part of a proposed approach to Intentionality based on the script theory of Roger Schank and Robert Abelson (1977). Scripts are schemata—organized knowledge structures that guide our understanding of the world around us. Schank and Abelson's basic ideas are extended to yield four different script-types: episodic (related to situations and events), instrumental (related to procedural knowledge), personal (representing an agent's goals and plans), and definitional (involved in object-recognition). The relationship between scripts and the Intentionality of thought is the main focus of this dissertation. An important secondary concern is the viability of externalism and internalism. It is argued that neither of these attitudes is independently adequate to provide a full account of Intentional content. Rather, the proper approach is to confine externalistic influences to aboutness and then characterize directedness in a manner that captures the world-according-to-the-agent. This strategy is implemented in the following way: aboutness is construed causally-evolutionarily; directedness is constructed with the help of the notion of an equivalence class; aspectual shape is shown to be a function of the kind of information a script provides; and an account of misrepresentation is given by comparing the different extensions generated from aboutness and directedness respectively.

description: We demonstrate that electron wave functions change their dimensionality at some commensurate directions of a magnetic field in conductors with open [quasi-one-dimensional (Q1D)] sheets of Fermi surface. These 1D -> 2D dimensional crossovers lead to delocalization of wave functions and are responsible for angular magnetoresistance oscillations. As an example, we show that suggested theory is in qualitative and quantitative agreements with the recent experimental data obtained on (TMTSF)2ClO4 conductor.

description: We propose a scheme to implement a two-qubit controlled-phase gate for single atomic qubits, which works in principle with nearly ideal success probability and fidelity. Our scheme is based on the cavity input-output process and the single photon polarization measurement. We show that, even with the practical imperfections such as atomic spontaneous emission, weak atom-cavity coupling, violation of the Lamb-Dicke condition, cavity photon loss, and detection inefficiency, the proposed gate is feasible for generation of a cluster state in that it meets the scalability criterion and it operates in a conclusive manner. We demonstrate a simple and efficient process to generate a cluster state with our high probabilistic entangling gate.

Gravity as elasticity of spacetime: a paradigm to understand horizon thermodynamics and cosmological constant

description: It is very likely that the quantum description of spacetime is quite different from what we perceive at large scales, $l\gg (G\hbar/c^3)^{1/2}$. The long wave length description of spacetime, based on Einstein's equations, is similar to the description of a continuum solid made of a large number of microscopic degrees of freedom. This paradigm provides a novel interpretation of coordinate transformations as deformations of "spacetime solid" and allows one to obtain Einstein's equations as a consistency condition in the long wavelength limit. The entropy contributed by the microscopic degrees of freedom reduces to a pure surface contribution when Einstein's equations are satisfied. The horizons arises as "defects" in the "spacetime solid" (in the sense of well defined singular points) and contributes an entropy which is one quarter of the horizon area. Finally, the response of the microstructure to vacuum energy leads to a near cancellation of the cosmological constant, leaving behind a tiny fluctuation which matches with the observed value.

description: Crude oil price speculation during 2000s could have increased installed capacity in corn ethanol plants beyond what was warranted by the market factors. We use Muth’s commodity pricing model and Flood and Garber’s tests to test for speculative investment in US corn ethanol industry. The ethanol price expectations are derived using a system of supply-demand-inventory describing US ethanol markets under rational expectations (perfect foresight). These price expectations can help differentiate the installed capacity into two: capacity supported by the market fundamentals and the probable capacity that is installed based on speculation. Econometric estimation procedures and functional form approximations are discussed.

description: SPIRou is the newest spectropolarimeter and high-precision velocimeter that has recently been installed at the Canada-France-Hawaii Telescope on Maunakea, Hawaii. It operates in the near-infrared and simultaneously covers the 0.98-2.35 μm domain at high spectral resolution. SPIRou is optimized for exoplanet search and characterization with the radial-velocity technique, and for polarization measurements in stellar lines and subsequent magnetic field studies. The host of the transiting hot Jupiter HD 189733 b has been observed during early science runs. We present the first near-infrared spectropolarimetric observations of the planet-hosting star as well as the stellar radial velocities as measured by SPIRou throughout the planetary orbit and two transit sequences. The planetary orbit and Rossiter-McLaughlin anomaly are both investigated and modeled. The orbital parameters and obliquity are all compatible with the values found in the optical. The obtained radial-velocity precision is compatible with about twice the photon-noise estimates for a K2 star under these conditions. The additional scatter around the orbit, of about 8 m/s, agrees with previous results that showed that the activity-induced scatter is the dominant factor. We analyzed the polarimetric signal, Zeeman broadening, and chromospheric activity tracers such as the 1083nm HeI and the 1282nm Pa\b{eta} lines to investigate stellar activity. First estimates of the average unsigned magnetic flux from the Zeeman broadening of the FeI lines give a magnetic flux of 290+-58 G, and the large-scale longitudinal field shows typical values of a few Gauss. These observations illustrate the potential of SPIRou for exoplanet characterization and magnetic and stellar activity studies.

description: Einstein-Maxwell-dilaton theory is an interesting theory of gravity for studying scalar fields in the context of no-hair theorem. In this work, we consider static charged dilaton and charged, slowly rotating dilaton black holes in Einstein-Maxwell-dilaton gravity. We investigate the accretion process in thin disks around such black holes, using the Novikov-Thorne model. The electromagnetic flux, temperature distribution, energy conversion efficiency and also innermost stable circular orbits of thin disks are obtained and effects of dilaton and rotation parameters are studied. For the static and slowly rotating black holes the results are compared to that of Schwarzschild and Kerr, respectively.

description: We apply the recently developed Log N - Log S test of compact star cooling theories for the first time to hybrid stars with a color superconducting quark matter core. While there is not yet a microscopically founded superconducting quark matter phase which would fulfill constraints from cooling phenomenology, we explore the hypothetical 2SC+X phase and show that the magnitude and density-dependence of the X-gap can be chosen to satisfy a set of tests: temperature - age (T - t), the brightness constraint, Log N - Log S, and the mass spectrum constraint. The latter test appears as a new conjecture from the present investigation.

description: This study examines the interaction between insurance, credit and liquidity constraints using a stochastic dynamic model. A risk averse farmer whose objective is to manage both production and market risk is assumed to maximize the expected utility of life-time consumption by using both area revenue (AR) insurance and consumption smoothing subject to a credit constraint. The dynamic programming is coded in MATLAB using DDPSOLVE algorithm (Appendix a). DSSAT crop simulation model is used to determine optimal irrigation strategy and to simulate farm level yield. A Bayesian Model is used to estimate expected county-level revenue. The approach and results are illustrated via a numerical example using county level data from Mitchell County in Georgia. Results support the hypothesis that liquidity constraints can have a large impact on optimal insurance decisions, and that different levels of premium load, risk aversion level, and time-preferences can also affect optimal insurance decisions under liquidity constraints.
Effects of dynamical evolution on the distribution of substructures

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We develop a semi-analytical model that determines the evolution of the mass, position and internal structure of dark matter substructures orbiting in dark matter haloes. We apply this model to the case of the Milky Way. We focus in particular on the effects of mass loss, dynamical friction and substructure--substructure interactions, the last of which has previously been ignored in analytic models of substructure evolution. Our semi-analytical treatment reproduces both the spatial distribution of substructures and their mass function as obtained from the most recent N-body cosmological calculations of Gao et al. (2004). We find that, if mass loss is taken into account, the present distribution of substructures is practically insensitive to dynamical friction and scatterings from other substructures. Implementing these phenomena leads to a slight increase (~5%) in the number of substructures at r<0.35 r_vir, whereas their effects on the mass function are negligible. We find that mass loss processes lead to the disruption of substructures before dynamical friction and gravitational scattering can significantly alter their orbits. Our results suggest that the present substructure distribution at r>0.35 r_vir reflects the orbital properties at infall and is, therefore, purely determined by the dark matter environment around the host halo and has not been altered by dynamical evolution.

description: We provide a unified analysis of a posteriori and a priori error bounds for a broad class of discontinuous Galerkin and $C^0$-IP finite element approximations of fully nonlinear second-order elliptic Hamilton--Jacobi--Bellman and Isaacs equations with Cordes coefficients. We prove the existence and uniqueness of strong solutions in $H^2$ of Isaacs equations with Cordes coefficients posed on bounded convex domains. We then show the reliability and efficiency of computable residual-based error estimators for piecewise polynomial approximations on simplicial meshes in two and three space dimensions. We introduce an abstract framework for the a priori error analysis of a broad family of numerical methods and prove the quasi-optimality of discrete approximations under three key conditions of Lipschitz continuity, discrete consistency and strong monotonicity of the numerical method. Under these conditions, we also prove convergence of the numerical approximations in the small-mesh limit for minimal regularity solutions. We then show that the framework applies to a range of existing numerical methods from the literature, as well as some original variants. A key ingredient of our results is an original analysis of the stabilization terms. As a corollary, we also obtain a generalization of the discrete Miranda--Talenti inequality to piecewise polynomial vector fields.

description: ABSTRACT Aim: To assess the long-term cost-effectiveness of an atrial fibrillation disease management program (i.e. the SAFETY program) from the Australian healthcare system perspective. Methods: A multistate Markov model was developed based on patient-level data from the SAFETY randomized controlled trial. Predicted long-term survival, dependent on hospital admission history, was estimated by extrapolating parametric survival models. Quality-adjusted life years (QALY) and life years (LY) were the primary and secondary outcome measures used to estimate the incremental costutility/effectiveness ratio (ICUR/ICER). Both deterministic and probabilistic sensitivity analyses (PSA) were undertaken. Results: The SAFETY program was associated with both higher costs ($94,953 vs. $78,433) and benefits [QALY (3.99 vs 3.60); LY (5.86 vs 5.24)], with an ICUR of $42,513/QALY or ICER of $26,356/LY, compared to standard care. Due to the extended survival, the SAFETY was associated with a greater number of hospitalizations (14.85 vs 11.65) and higher costs for medications ($25,084 vs $22,402) and outpatient care ($12,904 vs $11,524). The cost per hospitalization for an average length of stay, analytical time horizon, and cost of medication are key determinants of ICUR. The PSA showed that the intervention has a 70.4% probability of being cost-effective at a threshold of $50,000/QALY. Conclusions: The SAFETY program has a high probability of being cost-effective for patients with atrial fibrillation. It is associated with uncertainty that further research could potentially eliminate; implementation with further evidence collection is recommended.

description: A crystalline form of LiBC is known which has been predicted to be superconducting, with a Tc comparable to that of MgB_2. In both compounds, superconductivity is enhanced by the presence of two electronic bands, one of which is close to a dimensional crossover. Here, we take a quantum chemical approach, and investigate the structural and electronic properties of small clusters (LiBC)_n (n=1-4). With increasing cluster size, we find that several properties of crystalline LiBC evolve naturally from the corresponding properties of the clusters. In particular, one may recognize the origin of the solid bilayered structure, typical of magnesium diboride, and the character of the electronic sigma-band, arising from the overlap of the atomic orbitals in the in-plane BC rings. Two aspects especially emphasized are (a) the HOMO-LUMO gap as function of n and (b) the role of different spin multiplicity.

description: Recent observations have shown a remarkable diversity of observational behaviors and explosion mechanisms in thermonuclear supernovae (SNe). An emerging class of peculiar thermonuclear SNe, called Type Iax, show photometric and spectroscopic behaviors distinct from normal Type Ia. Their origin remains highly controversial, but pure turbulent deflagration of white dwarfs (WDs) has been regarded as the leading formation theory. The large population of Type Iax indicates the existence of unidentified Galactic Type Iax supernova remnants (SNRs). We report evidence that SNR Sgr A East in the Galactic center resulted from a pure turbulent deflagration of a Chandrasekhar-mass carbon-oxygen WD, an explosion mechanism used for Type Iax SNe. Our X-ray spectroscopic study of Sgr A East using 3 Ms of Chandra data shows a low ratio of intermediate-mass elements to Fe and large Mn/Fe and Ni/Fe ratios. This abundance pattern does not accord with the core-collapse or normal Type Ia models. Sgr A East is thus the first Galactic SNR for which a likely Type Iax origin has been proposed and the nearest target for studying this peculiar class. We compared Sgr A East with the Fe-rich SNRs 3C 397 and W49B, which also have high Mn and Cr abundances and were claimed to result from deflagration-to-detonation explosions of Chandrasekhar-mass WDs (although with disputes). Our study shows that they have distinct abundance patterns. The X-ray spectroscopic studies of thermonuclear SNRs provide observational evidence for the theories that there are diverse explosion channels and various metal outputs for Chandrasekhar-mass WDs.

description: Objective: Menopause is a physiological occurrence characterized by a series of bothersome symptoms. Given that lifestyle affects people’s health in general and many menopausal symptoms are influenced by changes in lifestyle, this study aimed to determine the relationship between lifestyle and severity of menopausal symptoms in women referred to health centers in Yazd city. Method: This cross-sectional study was performed using stratified random sampling where 343 postmenopausal women who had experienced natural menopause for 1-5 years, and did not have any chronic or debilitating disease were selected. The study was conducted in 2017 in Yazd city, Iran. The data collection tools were Walker’s Health Promoting Lifestyle Profile II (HPLP2) and Menopause Rating Scale (MRS) questionnaires. A multiple hierarchical linear regression was used to investigate the association between lifestyle and severity of menopausal symptoms. Results: The total mean ± (SD) score of menopausal symptoms severity and women’s lifestyle were 10.21 ± 6.55 and 126.44 ± 79.27, respectively. The results of multiple hierarchical linear regression showed a significantly negative association between lifestyle score and the mean score of menopausal symptoms severity in all three models (P-value <0.001). Conclusion: Our study concluded that healthier lifestyle reduces the severity of menopausal symptoms. These findings warrant that policy makers in the design of postmenopausal care plans and programs ought to pay special attention to the role of healthy lifestyles, including physical activity and healthy diet in enhancing menopausal symptoms. By preventing aggravation of menopausal symptoms; it is possible to economize on referrals to physicians and medicinal and therapeutic costs. Longitudinal and intervention studies with larger sample size may be required to confirm these findings.

description: Credibility building activities in computational research include verification and validation, reproducibility and replication, and uncertainty quantification. Though orthogonal to each other, they are related. This paper presents validation and replication studies in electromagnetic excitations on nanoscale structures, where the quantity of interest is the wavelength at which resonance peaks occur. The study uses the open-source software PyGBe: a boundary element solver with trecode acceleration and GPU capability. We replicate a result by Rockstuhl et al. (2005, doi:10/dsxw9d) with a two-dimensional boundary element method on silicon carbide particles, despite differences in our method. The second replication case from Ellis et al. (2016, doi:10/f83zcb) looks at aspect ratio effects on high-order modes of localized surface phonon-polariton nanostructures. The results partially replicate: the wavenumber position of some mode match, but for other modes they differ. With virtually no information about the original simulations, explaining the discrepancies is not possible. A comparison with experiments that measured polarized reflectance of silicon carbide nano pillars provides a validation case. The wavenumber of the dominant mode and two more do match, but differences remain in other minor modes. Results in this paper were produced with strict reproducibility practices, and we share reproducibility packages for all, including input files, execution scripts, secondary data, post-processing code and plotting scripts, and the figures (deposited in Zenodo). In view of the many challenges faced, we propose that reproducible practices make replication and validation more feasible.

description: Статья посвящена обсуждению некоторых проблем, возникающих при взаимодействии нейротехнологий и виртуальной реальности при использовании наиболее применяемых в настоящее время межплатформенных сред разработки компьютерных игр (Unreal Engine 4, Unity). На сегодняшний день нейротехнологии достигли значительного развития, получив признание и применение во многих областях сферы общества. Они оказывают значительное влияние на окружающий нас мир, в связи с чем возможность их комбинированного с виртуальной реальностью применения является весьма ожидаемым явлением. Приводятся основные сведения о принципах разработки виртуальной реальности и совместимости с нейротехнологиями. Необходимо учитывать, что программирование виртуальной реальности в разных средах, имея общие основы, обладает индивидуальными особенностями реализации — от различной последовательности действий до полной замены некоторых шагов.
Let’s shop online together : an investigation of online collaborative shopping support
Creators: name: Zhu, Lei
Publisher: name: University of British Columbia
Year: 2009

description: A large number of studies conducted to investigate business-to-consumer e-commerce have focused exclusively on individual online shopping, but consumers often desire to conduct their shopping activities with others. This study explores the important yet understudied research area of collaborative online shopping. We investigate the design issues of an online collaborative shopping support tool and its impact on web consumers' attitude formation and intention to adopt online collaborative shopping. In particular, we examine two important functions of an online collaborative shopping support tool, namely collaborative browsing support and instant voice chatting support. We propose these two functions will positively affect the perceived ease of use and perceived usefulness of an online collaborative shopping support tool, and shopping enjoyment and telepresence in online collaborative shopping. These four factors are expected to positively affect web consumers' attitudes towards online collaborative shopping and their behavioral intention. A two by two mixed factorial design was used to test the linkages proposed above. We recruited sixty-four pairs of participants to participate in a laboratory experiment. The results indicate that collaborative browsing support increases a web consumer's perception of usefulness of an online collaborative shopping support tool; collaborative browsing support increases shopping enjoyment and telepresence in online collaborative shopping; and perceived ease of use of the browsing support tool is not supported. Instant voice chatting support increases perceived ease of use and perceived usefulness of an online collaborative shopping support tool, and shopping enjoyment and telepresence in online collaborative shopping. Perceive usefulness, and shopping enjoyment are important in improving consumers' attitudes towards online collaborative shopping and their intention to shop together with friends online. This research addresses a gap in our current understanding of web users' behavior. The implications of the research for both researchers and practitioners are discussed.

Site percolation thresholds on triangular lattice with complex neighborhoods
Creators: name: Malarz, Krzysztof
Publisher: name: arXiv
Year: 2020
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We determine thresholds $p_c$ for random site percolation on a triangular lattice for neighbourhoods containing nearest (NN), next-nearest (2NN), next-next-nearest (3NN), next-next-next-nearest (4NN) and next-next-next-next-nearest (5NN) neighbours, and their combinations forming regular hexagons (3NN+2NN+NN, 5NN+4NN+NN, 5NN+4NN+3NN+2NN, 5NN+4NN+3NN+2NN+NN). We use a fast Monte Carlo algorithm, by Newman and Ziff [M. E. J. Newman and R. M. Ziff, Physical Review E 64, 016706 (2001)], for obtaining the dependence of the largest cluster size on occupation probability. The method is combined with a method, by Bastas et al. [N. Bastas, K. Kosmidis, P. Giazitzidis, and M. Maragakis, Physical Review E 90, 062101 (2014)], of estimating thresholds from low statistics data. The estimated values of percolation thresholds are $p_c(\text{4NN})=0.192410(43)$, $p_c(\text{3NN+2NN})=0.232008(38)$, $p_c(\text{5NN+4NN})=0.140286(5)$, $p_c(\text{3NN+2NN+NN})=0.215484(19)$, $p_c(\text{5NN+4NN+NN})=0.131792(58)$, $p_c(\text{5NN+4NN+3NN+2NN})=0.117579(41)$, $p_c(\text{5NN+4NN+3NN+2NN+NN})=0.115847(21)$. The method is tested on the standard case of site percolation on triangular lattice, where $p_c(\text{NN})=p_c(\text{2NN})=p_c(\text{3NN})=p_c(\text{5NN})=\frac{1}{2}$ is recovered with five digits accuracy $p_c(\text{NN})=0.500029(46)$ by averaging over one thousand lattice realisations only.

description: Introduction and Purpose: Males who excel at sport whilst still at school trivialize education in favour of sport. This study of 12 male Australian footballers aims to examine the hierarchy between education and sport of Australian footballers. Material and Method: Four rugby league, four rugby union and four Australian Rules footballers underwent life history interviews and showed clear prioristation of sport during school. Results: However, the importance of education post-secondary school was recognized by these footballers. This change in perspective supports current research and extends the research by describing perspectives of Australian Footballers post-secondary school. Summary: These findings are interesting in that they demonstrate the initial ascendancy of sport and the retrospective significance of education over sport.

description: Introduction: The Healthy Homes and Neighbourhoods (HHAN) Integrated Care Program seeks to enhance vulnerable family engagement with health and social services through a care coordination model. Besides servicing families in Sydney, HHAN has also established place-based initiatives (PBIs) in areas of disadvantage such as Redfern. The Redfern PBI co-locates HHAN with housing, drug and alcohol services, and financial and legal services. This integration aims to facilitate service access and multi-agency support for vulnerable families in Redfern. Hence, this study aims to evaluate for whom, when and why HHAN’s PBI at Redfern works, or not, and what are its outcomes. Methods: The project utilises critical realist methodology to undertake a qualitative evaluation of the impact of the PBI on clients, services and the community. Purposive sampling was used to identify 21 participants including HHAN clients, HHAN staff and stakeholders (HHAN partners). In-depth, semi-structured interviews were audio-recorded, transcribed, coded and analysed using a context (C), intervention (I), mechanism (M) outcome (O) (CIMO) approach to abductive analysis. Results: Five key CIMO configurations of the Redfern PBI emerged – whole-of-family involvement, flexibility, trust, building connections and co-location. Whilst each theory had specific outcomes, overall client outcomes included improved access to services, better outlook, empowerment and engagement with services. Service outcomes included increased collaboration and foundation for integration between HHAN and other services. Negative outcomes included lack of full integration, the risk associated with integration and difficulty evaluating impact. Conclusion: This study successfully refined the program theory for subsequent use in later implementation of critical realist evaluation studies.

description: This paper shows that the effects of the U.S. blender’s tax credit of $1/gallon and ‘splash & dash’ had minimal impacts on the EU biodiesel market. Reduced world oil prices and EU tax exemptions, increased rapeseed oil prices and market uncertainty are shown empirically to be the major contributors to reduced profitability of EU biodiesel production. Nevertheless, the EU imposed tariffs sometimes exceeding the tax credit in retaliation for the U.S. ‘splash & dash’ program. Instead, EU imports from the United States can be beneficial for EU taxpayers, fuel consumers as well as U.S. biodiesel producers.
