description: Optical imaging systems are inherently limited in their resolution due to the point spread function (PSF), which applies a static, yet spatially-varying, convolution to the image. This degradation can be addressed via Convolutional Neural Networks (CNNs), particularly through deblurring techniques. However, current solutions face certain limitations in efficiently computing spatially-varying convolutions. In this paper we propose CoordGate, a novel lightweight module that uses a multiplicative gate and a coordinate encoding network to enable efficient computation of spatially-varying convolutions in CNNs. CoordGate allows for selective amplification or attenuation of filters based on their spatial position, effectively acting like a locally connected neural network. The effectiveness of the CoordGate solution is demonstrated within the context of U-Nets and applied to the challenging problem of image deblurring. The experimental results show that CoordGate outperforms conventional approaches, offering a more robust and spatially aware solution for CNNs in various computer vision applications.
Sustainability in the Food Sector: A Consumer Behaviour Perspective

Publisher: name: CentMA
Year: 2011
Subjects: Sustainability; consumer behaviour; hierarchy of effects; eco-labels

description: Consumers have, through their food choices, a major role in bringing about more sustainable food production. However, this presupposes that differences in sustainability are communicated to consumers. Even if food products are eco-labelled and consumers are motivated to support sustainability, a number of potential barriers may prevent consumers from using the information to make sustainable choices. Six such barriers are discussed in this paper.

description: We present exact analytical results for the differential conductance of a finite Kitaev chain in an N-S-N configuration, where the topological superconductor is contacted on both sides with normal leads. Our results are obtained with the Keldysh non-equilibrium Green's functions technique, using the full spectrum of the Kitaev chain without resorting to minimal models. A closed formula for the linear conductance is given, and the analytical procedure to obtain the differential conductance for the transport mediated by higher excitations is described. The linear conductance attains the maximum value of $e^2/h$ only for the exact zero energy states. Also the differential conductance exhibits a complex pattern created by numerous crossings and anticrossings in the excitation spectrum. We reveal the crossings to be protected by the inversion symmetry, while the anticrossings result from a pairing-induced hybridization of particle-like and hole-like solutions with the same inversion character. Our comprehensive treatment of the Kitaev chain allows us also to identify the contributions of both local and non-local transmission processes to transport at arbitrary bias voltage. Local Andreev reflection processes dominate the transport within the bulk gap and diminish for higher excited states, but reemerge when the bias voltage probes the avoided crossings. The non-local direct transmission is enhanced above the bulk gap, but contributes also to the transport mediated by the topological states.

description: The paper contribute to the assessment of PDO/PGI schemes by building an approach to measuring the actual performance of the PDO/PGI products in relation to the objectives of the European Regulation 510/2006. This is done through a multi-criteria ex-post analysis that compares the performance of different PDO/PGI products with respect to multiple criteria. The research presented, based on a small sample of Pdo cheese products in Italy, can be considered a pilot study that develops a comparative evaluation of the performance of PDO cheeses: i) relative to the different objectives of the schemes, ii) by using a set of suitable and informative indicators that can help to evaluate the effectiveness of a wide number of PDOs/PGIs with respect to the regulation’s objectives, and iii) by considering that different actors involved in PDO/PGI schemes may have different priorities with regard to the importance of different objectives in evaluating the performance of schemes.

Characterization and developmental expression patterns of the ubiquitin-conjugating enzyme UBC-2 in the nematode Caenorhabditis elegans
Creators: name: Stevens, Tracy Alison
Publisher: name: University of British Columbia
Year: 2009

description: The role of the essential ubiquitin-conjugating enzyme, UBC-2, during development in the nematode Caenorhabditis elegans was examined. The mutant strain, let-70, which corresponded to ubc-2, was L3 larval lethal, and indicated that UBC-2 was required post-embryonically. Additionally, a maternal contribution of UBC-2 was necessary for embryonic development. Detailed analysis of let-70(s1132) and let-70(s689) mutant phenotypes revealed defects in muscle cell positioning, attachment and sarcomere assembly. Intestinal cell attachment and maturation were also affected. A small number of let-70(s689) mutants developed into sterile adults with gonadal defects. In these mutants, the somatic gonad and vulva did not develop properly, only a small number of germ cells were produced, and oocytes and spermatocytes failed to mature. UBC-2 protein was undetectable in let-70(s1132) and let-70(s689) mutants. The let-70(s689) mutation altered the splice donor site of the fourth intron. In affected animals, the fourth intron was not removed from the ubc-2 pre-mRNA, and the transcript was subject to smg-mediated mRNA surveillance. The mutant UBC-2 protein produced in let-70(s1132) appeared to be highly unstable. The let-x(s2293) strain was identified in a non-complementation screen for additional alleles of let-70 and was a large deletion that spanned several essential genes, including ubc-2. The UBC-2 expression pattern during development was determined by immunofluorescence staining and examination of transgenic animals carrying a UBC-2::GFP fusion construct. UBC-2 expression was largely tissue general in embryonic stages. Post-embryonically, UBC-2 remained tissue general, although a large amount of protein became concentrated in the nucleoli of a number of cells, including intestinal, body wall muscle, hypodermal, somatic gonad, germline, pharyngeal muscle, pharyngeal-intestinal valve and several neurons. In addition, UBC-2 localized to the dense bodies or M-lines of body wall muscle, and a few neuronal cell processes. In let-70 mutants, this expression pattern was lost. Somatic and germline expression of an extrachromosomal array that contained ubc-2 could rescue let-70(s689), but not let-70(s1132) mutants. A cold-sensitive allele of ubc-2 was constructed which was also capable of rescuing let-70(s689) mutants in a temperature-dependent manner. ubc-2 forms part of a polycistronic unit with two other genes, apg-7 and Y5F2A.4. Both ubc-2 and Y5F2A.4 are exclusively SL1-spliced while apg-7 is SL1- and SL2-spliced. Comparison of the ubc-2 polypeptide sequence between C. elegans and C. briggsae revealed 100% identity; however, C. briggsae UBC-2 was unable to rescue let-70 mutants. A high degree of synteny exists between the genomic sequences surrounding the C. elegans and C. briggsae ubc-2 genes, with the exception of sequences immediately surrounding the ubc-2 operon.
Jets, Structured Outflows, and Energy Injection in GRB Afterglows: Numerical Modelling
Creators: name: Panaitescu, A.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: We investigate numerically the ability of three models (jet, structured outflow, energy injection) to accommodate the optical light-curve breaks observed in 10 GRB afterglows (980519, 990123, 990510, 991216, 000301c, 000926, 010222, 011211, 020813, and 030226), and the relative intensities of the radio, optical, and X-ray emissions of these afterglows. We find that the jet and structured outflow models fare much better than the energy injection model in accommodating the multiwavelength data of the above 10 afterglows. For the first two models, a uniform circumburst medium provides a better fit to the optical light-curve break than a wind-like medium with a r^{-2} stratification. However, in the only two cases where the energy injection model may be at work, a wind medium is favoured (an energy injection is also possible in a third case, the afterglow 970508, whose optical emission exhibited a sharp rise but not a steepening decay). The best fit parameters obtained with the jet model indicate an outflow energy of 2-6 E50 ergs and a jet opening of 2-3 degrees. Structured outflows with a quasi-uniform core have a core angular size of 0.7-1.0 degrees and an energy per solid angle of 0.5-3 E53 erg/sr, surrounded by an envelope where this energy falls-off roughly as theta^{-2} with angle from the outflow axis, requiring thus the same energy budget as jets. Circumburst densities are found to be typically in the range 0.1-1 per cc, for either model. We also find that the reverse shock emission resulting from the injection of ejecta into the decelerating blast wave at about 1 day after the burst can explain the slowly decaying radio light-curves observed for the afterglows 990123, 991216, and 010222.

description: Given the coronavirus disease 2019 (COVID-19) pandemic, investigations into host susceptibility to infectious diseases and downstream sequelae have never been more relevant. Pneumonia is a lung disease that can cause respiratory failure and hypoxia and is a common complication of infectious diseases, including COVID-19. Few genome-wide association studies (GWASs) of host susceptibility and severity of pneumonia have been conducted. We performed GWASs of pneumonia susceptibility and severity in the Vanderbilt University biobank (BioVU) with linked electronic health records (EHRs), including Illumina Expanded Multi-Ethnic Global Array (MEGAEX)-genotyped European ancestry (EA, n= 69,819) and African ancestry (AA, n = 15,603) individuals. Two regions of large effect were identified: the CFTR locus in EA (rs113827944; OR = 1.84, p value = 1.2 × 10−36) and HBB in AA (rs334 [p.Glu7Val]; OR = 1.63, p value = 3.5 × 10−13). Mutations in these genes cause cystic fibrosis (CF) and sickle cell disease (SCD), respectively. After removing individuals diagnosed with CF and SCD, we assessed heterozygosity effects at our lead variants. Further GWASs after removing individuals with CF uncovered an additional association in R3HCC1L (rs10786398; OR = 1.22, p value = 3.5 × 10−8), which was replicated in two independent datasets: UK Biobank (n = 459,741) and 7,985 non-overlapping BioVU subjects, who are genotyped on arrays other than MEGAEX. This variant was also validated in GWASs of COVID-19 hospitalization and lung function. Our results highlight the importance of the host genome in infectious disease susceptibility and severity and offer crucial insight into genetic effects that could potentially influence severity of COVID-19 sequelae.

description: The increase in the level of greenhouse gas (GHG) emissions in the atmosphere in the last centuries, and the subsequent increase in temperature, has been a widely studied area in the last few decades. Climate change has become a key item on the political agenda due to concerns regarding the sustainability of current human consumption for future generations. Consumption of food and agricultural goods constitutes an important part of household based GHG emissions, and the relatively low costs associated with environmental improvements make it an interesting area of study to understand behavioural changes.
Despite general agreement on the need to curb the amount of GHG emissions worldwide, little evidence exists regarding the best instruments policymakers can employ to stimulate changes toward more sustainable consumption. The present work explores which instruments are most effective in fostering change to more environmentally friendly food consumption. The instruments tested are CO

2 labelling, GHG abatement subsidy and product-specific bans. We used a simulated online shopping trip in supermarkets in the Greater London area in the United Kingdom, where respondents shopped in four product categories: cola, milk, meat (chicken and beef), and butter/margarine. Consumer preferences reveal that, in the presence of these instruments, quantity instruments performed better than price incentives and labelling.

description: The Soil and Water Assessment Tool (SWAT) model is a continuation of nearly 30 years of modeling efforts conducted by the U.S. Department of Agriculture (USDA), Agricultural Research Service. SWAT has gained international acceptance as a robust interdisciplinary watershed modeling tool, as evidenced by international SWAT conferences, hundreds of SWAT-related papers presented at numerous scientific meetings, and dozens of articles published in peer-reviewed journals. The model has also been adopted as part of the U.S. Environmental Protection Agency's BASINS (Better Assessment Science Integrating Point & Nonpoint Sources) software package and is being used by many U.S. federal and state agencies, including the USDA within the Conservation Effects Assessment Project. At present, over 250 peer-reviewed, published articles have been identified that report SWAT applications, reviews of SWAT components, or other research that includes SWAT. Many of these peer-reviewed articles are summarized here according to relevant application categories such as streamflow calibration and related hydrologic analyses, climate change impacts on hydrology, pollutant load assessments, comparisons with other models, and sensitivity analyses and calibration techniques. Strengths and weaknesses of the model are presented, and recommended research needs for SWAT are provided.
A Nonlinear Master Equation for Open Quantum Systems

description: A nonlinear master equation is derived, reflecting properly the entropy of open quantum systems. In contrast to linear alternatives, its equilibrium solution is exactly the canonical Gibbs density matrix. The corresponding nonlinear equation for the Wigner function accounts rigorously for the thermo-quantum entropy. It reduces at large friction to the Smoluchowski-Bohm equation in the coordinate subspace, which reflects the stochastic Langevin-Bohm dynamics. The previously derived Maxwell-Heisenberg relation for the nonequilibrium momentum dispersion of quantum Brownian particles is confirmed as well as the related quantum generalization of the classical Einstein law of Brownian motion.

description: By using an econometric approach this paper looks at the evolution of the world wine industry in the period 1961-2005. A particular stylized fact is the appearance of nontraditional producing and exporting countries of wine from the beginning of the nineties. We show that the success of these new producing and exporting countries can be explained by the importance of the demand from non-producing countries with little or no tradition of wine consumption, relative to the world demand. This stylized fact is consistent with a testable implication of the switching cost literature and to the best of our knowledge this is the first time that this implication is tested.

description: We discuss the problem of gauge fixing for strongly correlated electrons coupled to quantum light, described by projected low-energy models such as those obtained within tight-binding methods. Drawing from recent results in the field of quantum optics, we present a general approach to write down quantum light-matter Hamiltonian in either dipole or Coulomb gauge which are explicitly connected by a unitary transformation, thus ensuring gauge equivalence even after projection. The projected dipole gauge Hamiltonian features a linear light-matter coupling and an instantaneous self-interaction for the electrons, similar to the structure in the full continuum theory. On the other hand, in the Coulomb gauge the photon field enters in a highly non-linear way, through phase factors that dress the electronic degrees of freedom. We show that our approach generalises the well-known Peierls approximation, to which it reduces when only local, on-site orbital contributions to light-matter coupling are taken into account. As an application, we study a two-orbital model of interacting electrons coupled to a uniform cavity mode, recently studied in the context of excitonic superradiance and associated no-go theorems. Using both gauges we recover the absence of superradiant phase in the ground state and show that excitations on top of it, described by polariton modes, contain instead non-trivial light-matter entanglement. Our results highlight the importance of treating the non-linear light-matter interaction of the Coulomb gauge non-perturbatively, to obtain a well-defined ultrastrong coupling limit and to not spoil gauge equivalence.

description: The objective of this paper is to offer qualitative and quantitative insights on the perceptions of the actors in the EU food supply chain on a broad spectrum of topics that characterise its operation and conduct, highlighting also potential differences in North and South European countries. Issues explored pertained to actors’ relations with up- and downstream partners, the future dynamic and challenges of the food sector, the influence of policy intervention and attitudes towards genetically modified products (GMPs) and organic production. For this purpose, a total of 34 food supply chain actors in Denmark and Greece were interviewed using a semi-structured interview process. A comparative analysis of the interviews pinpointed many similarities in the behaviour and the perceptions of the Greek and Danish farmers, cooperatives, processors and retailers alike. Still, while it is evident that companies and farmers of both countries struggle with a lot of the same problems, several differences in perceptions are also identified. These refer mainly to attitudes towards mergers and acquisitions, innovations, GMPs and the effects and limitations of EU policy intervention.

The Compliance Process of Food Quality Standards on Primary Producer Level: A Case Study of the EUREPGAP Standard in the Moroccan Tomato Sector

Subjects: Food Consumption/Nutrition/Food Safety

description: Fruit and vegetable sectors are principally seen as sectors where small producers are able to participate due to their low demand on land and their high labor requirements. However, the concern exists that small producers' participation in the international fruit and vegetable trade could be diminishing as a result of the increasing prevalence of food quality standards in the sector. Standards define the terms of chain membership, imply rules and conditions for participation, and hence lead to processes of (re)distribution within the chain (Gibbon and Ponte, 2005). For some producers, standards may open up new opportunities as they permit market access to particular market segments. At the same time, the process of (re)distributing market shares is accompanied by marginalization and exclusion, as standards may impose prohibitively high barriers for certain producers in terms of the short-term and long-term efforts needed for production under certification. This is particularly relevant since certification with private standards has become a major requirement for participation in fruit and vegetable markets worldwide. One of the most important private standards for fruit and vegetables is the EUREPGAP standard, which has now become quasi-mandatory for several export destinations (USAID, 2005). This paper aims to analyze two particular questions with regard to the distributional effects of standards: 1) which producers comply, and which do not; and 2) why do some producers comply while others do not? With respect to the first question, various surveys have mentioned the particular difficulties facing small producers within this new trading environment (e.g. Humphrey et al. 2004; Kleinwechter and Grethe 2006; Maertens and Swinnen 2006; World Bank 2005). However, most of these surveys have hypothesized that small producers are disadvantaged within the new trading environment on theoretical grounds without actually providing empirical evidence for this assertion.

description: The paper considers the wave equation, with constant or variable coefficients in $\R^n$, with odd $n\geq 3$. We study the asymptotics of the distribution $μ_t$ of the random solution at time $t\in\R$ as $t\to\infty$. It is assumed that the initial measure $μ_0$ has zero mean, translation-invariant covariance matrices, and finite expected energy density. We also assume that $μ_0$ satisfies a Rosenblatt- or Ibragimov-Linnik-type space mixing condition. The main result is the convergence of $μ_t$ to a Gaussian measure $μ_\infty$ as $t\to\infty$, which gives a Central Limit Theorem (CLT) for the wave equation. The proof for the case of constant coefficients is based on an analysis of long-time asymptotics of the solution in the Fourier representation and Bernstein's `room-corridor' argument. The case of variable coefficients is treated by using a version of the scattering theory for infinite energy solutions, based on Vainberg's results on local energy decay.

description: Background: Our aim was to investigate if moderate to vigorous physical activity (MVPA), calcium intake interacts with bone mineral density (BMD)-related single nucleotide polymorphisms (SNPs) to influence BMD in 750 Hispanic children (4-19y) of the cross-sectional Viva La Familia Study. Methods: Physical activity and dietary intake were measured by accelerometers and multiple-pass 24 h dietary recalls, respectively. Total body and lumbar spine BMD were measured by dual energy X-ray absorptiometry. A polygenic risk score (PRS) was computed based on SNPs identified in published literature. Regression analysis was conducted with PRSs, MVPA and calcium intake with total body and lumbar spine BMD. Results: We found evidence of statistically significant interaction effects between the PRS and MVPA on total body BMD and lumbar spine BMD (p < 0.05). Higher PRS was associated with a lower total body BMD (β = − 0.040 ± 0.009, p = 1.1 × 10− 5) and lumbar spine BMD (β = − 0.042 ± 0.013, p = 0.0016) in low MVPA group, as compared to high MVPA group (β = − 0.015 ± 0.006, p = 0.02; β = 0.008 ± 0.01, p = 0.4, respectively). Discussion: The study indicated that calcium intake does not modify the relationship between genetic variants and BMD, while it implied physical activity interacts with genetic variants to affect BMD in Hispanic children. Due to limited sample size of our study, future research on gene by environment interaction on bone health and functional studies to provide biological insights are needed. Conclusions: Bone health in Hispanic children with high genetic risk for low BMD is benefitted more by MVPA than children with low genetic risk. Our results may be useful to predict disease risk and tailor dietary and physical activity advice delivery to people, especially children.

description: Understanding how the electronic excitation of DNA changes in response to different high-energy particles is central to advancing ion beam cancer therapy. While protons have been the predominant ion of choice in beam cancer therapy, heavier ions, particularly carbon ions, have drawn significant attention over the past decade. Carbon ions are expected to transfer larger amounts of energy accordingly to the linear response theory. However, the molecular-level details of the electronic excitation under heavier ion irradiation remain unknown. In this work, we use real-time time-dependent density functional theory simulations to examine the quantum-mechanical details of DNA electronic excitations in water under proton, alpha-particle, and carbon ion irradiation. Our results show that the energy transfer does indeed increase for the heavier ions, while the excitation remains highly conformal. However, the increase in the energy transfer rate, measured by electronic stopping power, does not match the prediction by the linear response model, even when accounting for the velocity-dependence of the irradiating ions charge. The simulations also reveal that while the number of holes generated on DNA increases for heavier ions, the increase is only partially responsible for the larger stopping power. Larger numbers of highly energetic holes formed from the heavier ions also contribute significantly to the increased electronic stopping power.

description: The probability that actors in economic relationships break rules increases with the profits they thus expect to earn. It decreases with the probability and level of short- and long-term losses resulting from disclosure. It also decreases with the level of social context factors and intrinsic values which shield actors from yielding to economic temptations. This paper assesses the relative merits of various scientific approaches concerned with risks in economic relationships and outlines their contribution to the study of opportunistic rule-breaking. Since the identification of (misdirected) economic incentives faced by firms and individuals represents the starting point for a systematic analysis of opportunism in any field, we also outline a microeconomic approach that systematically provides this crucial information. The approach is applied to the problem of food quality and safety threatened by opportunistic malpractice of food business operators. Its essentials are illustrated through a study which systematically searches for the temptations to break production-related rules in the poultry industries.

description: Despite the modest regional consumption of organic products, Sicily is one of the most important European regions in surface area per number of companies active in organic farming. The University of Palermo, as early as 2000, to promote the development and success in this industry, the Faculty of Agriculture, introduced two major degree programs in "Organic Farming". The objective of these courses is to train graduates who are technically capable of supporting the organic farmers market, to promote and facilitate the expansion of the consumption of organic products, and to create employment opportunities for young graduates.
At the end of 2009, in the area of these activities, a training and research program involved numerous students in the creation of an "joint consumption" association whose purpose is the expansion of the consumption of organic products through the enhancement of a direct relationship with small organic farms who would be unlikely to penetrate large markets, or have relationships with large distribution networks.

The project aims to assess the ability of the students of the Faculty to transmit the knowledge acquired in the program, and to investigate the relative issues regarding the new phenomenon emerging in recent years in Italy, represented by the spread of various forms of ethically-conscious consumption groups called "Gruppi di Acquisto Solidale (GAS)" or Solidarity Purchase Groups.

description: A complex structure of the superconducting order parameter in $Ln_2$C$_3$ ($Ln$ = La, Y) is demonstrated by muon spin relaxation ($μ$SR) measurements in their mixed state. The muon depolarization rate [$σ_{\rm v}(T)$] exhibits a characteristic temperature dependence that can be perfectly described by a phenomenological double-gap model for nodeless superconductivity. While the magnitude of two gaps is similar between La$_2$C$_3$ and Y$_2$C$_3$, a significant difference in the interband coupling between those two cases is clearly observed in the behavior of $σ_{\rm v}(T)$.

description: We study the effect of spin-orbit scattering on the statistics of the conductance of a quantum dot for Coulomb blockade peaks and valleys. We find the distribution function of the peak heights for strong spin-orbit scattering in the presence and absence of time reversal symmetry. We find that the application of a magnetic field suppresses the average peak height, similar to the antilocalizaion in the bulk systems. For the valleys, we consider the elastic cotunneling contribution to the conductance and calculate its moments at the crossover between ensembles of various symmetries.

description: Charge multiplication through avalanche processes is commonly employed in the detection of single photons or charged particles in high-energy physics and beyond. In this report, we provide a detailed discussion of the properties of avalanches driven by two species of charge carriers, e.g. electrons and holes in a semiconductor exposed to an electric field. We derive equations that describe the general case of avalanches developing in inhomogeneous electric fields and give their analytical solutions for constant fields. We discuss consequences for the time resolution achievable with detectors that operate above the breakdown limit, e.g. single-photon avalanche diodes (SPADs) and silicon photomultipliers (SiPMs). Our results also describe avalanches that achieve finite gain and are important for avalanche photodiodes (APDs) and low-gain avalanche detectors (LGADs).

description: The chemical enrichment of X-ray-emitting hot atmospheres has hitherto been primarily studied in galaxy clusters. These studies revealed relative abundances of heavy elements that are remarkably similar to Solar. Here, we present measurements of the metal content of M89 (NGC 4552), an elliptical galaxy infalling into the Virgo cluster with a $\sim$10 kpc ram-pressure stripped X-ray tail. We take advantage of deep Chandra and XMM-Newton observations, and with particular attention to carefully modelling the spectra, we measure the O/Fe, Ne/Fe, Mg/Fe, Si/Fe and S/Fe ratios. Contrary to previous measurements in galaxy clusters, our results for the hot atmosphere of M89 suggest super-Solar abundance ratios with respect to iron (i.e. $α$/Fe > 1), similar to its stellar components. Our analysis of the active galactic nucleus (AGN) activity in this system indicates that the AGN-induced outflow could have facilitated the stripping of the original galactic atmosphere, which has been replaced with fresh stellar mass loss material with super-Solar $α$/Fe abundance ratios. Additionally, we report a new fitting bias in the RGS data of low-temperature plasma. The measured O/Fe ratios are >1$σ$ lower in multi-temperature models than a single temperature fit, leading to discrepancies in the calculations of supernova fractions derived from the metal abundances.

description: This paper shows the results of empirical research conducted to assess the sustainability of a typical food supply chain, suggesting feasible solutions to satisfy inter-dimensional requisites of durable development. The analysis was conducted with reference to the supply chain of the San Marzano tomato (SMZ), a typical local food. The product is endowed with an origin certification label (PDO), meeting demand within high-value market niches. The SMZ is a flagship product in the Italian region of Campania and has benefited from several regionally funded interventions, such as genetic research and support for the application for EU certification of origin). Two key findings emerged from the research. First, the results allowed us to define a Stakeholder Priority and Responsibilities’ Matrix (SPRM), and monitor the sustainability trend of SMZ food supply chains. Second, the consistency between the adoption of quality strategy (brand of origin) and sustainable development of the sector was evaluated. Despite its intrinsic characteristics and its organized, well-defined structure, the SMZ food supply chain is unable to address sustainable objectives without considerable public intervention and support. In terms of sustainability, to be able to show desirable food chain characteristics, the existence of a fully collaborative relationship between the actors has to be ascertained. Identifying shared goals is essential to assign and implement coordinated actions, pooling responsibility for product quality into social and environmental dimensions.

The application of spatial models in the analysis of bilateral trade flows: An alternative to the Armington approach for the world sugar market

description: This paper suggests spatial models as an alternative to the Armington approach to model bilateral trade. While the use of spatial models has been accepted for decades, they are rarely chosen for such analyses. However, problems inherent in the application of the Armington approach can be overcome through the use of spatial models. To demonstrate, a simple spatial model of the world sugar market is built and used to simulate a multilateral liberalization scenario. Additionally, an identical model is constructed, applying the Armington approach. The results of the spatial model of the sugar market are found to be more plausible than those generated by the Armington-based model.
