description: After a burst of enthusiasm through the middle part of this decade regarding the supermarket revolution, there now exists a broad consensus that this phenomenon is likely to proceed much more slowly than once thought in Sub-Saharan Africa. This is especially true in fresh produce supply chains, where both the promise and the perils of supermarket expansion have received greatest attention. In nearly the entire continent, the so-called traditional marketing sector – open air markets, dispersed informal vendors, and traditional shops – is expected to play a dominant role in fresh produce marketing for several decades. If true, this finding has profound policy implications. Specifically, it suggests that private investment in modern, integrated supply chains cannot be relied upon to solve the multitude of problems that increasingly plague these traditional production and marketing systems over a time frame acceptable to most policy makers and donors. Public engagement, preferably through meaningful public-private partnerships and an accompanying re-definition of public and private roles, will be central to improving these systems. This paper first reviews the evolution of thinking on the supermarket revolution in Africa and presents empirical evidence from Kenya and Zambia. It then lays out a set of stylized facts and key gaps in knowledge regarding traditional fresh produce production and marketing sectors on the continent, and closes by outlining priorities for research and for public and private investment to modernize these systems in the absence of rapid supermarket takeover.

description: We show that duality transformations of linearized gravity in four dimensions, i.e., rotations of the linearized Riemann tensor and its dual into each other, can be extended to the dynamical fields of the theory so as to be symmetries of the action and not just symmetries of the equations of motion. Our approach relies on the introduction of two "superpotentials", one for the spatial components of the spin-2 field and the other for their canonically conjugate momenta. These superpotentials are two-index, symmetric tensors. They can be taken to be the basic dynamical fields and appear locally in the action. They are simply rotated into each other under duality. In terms of the superpotentials, the canonical generator of duality rotations is found to have a Chern-Simons like structure, as in the Maxwell case.

description: From 1986 to 2007 Egypt’s agricultural policy transitioned from a tightly controlled to a more liberalized regime. This study examines the impact of this change on the performance of the wheat (imported grain) and rice (exported grain) sectors. In terms of profitability, we found that the cost of production increased substantially in both grains, driven primarily by the rise in land rent and labor wage. But the wheat and rice sectors’ profitability did not suffer significantly, as advances in new seed technologies and adoption of better farm practices including farm mechanization increased yield and compensated for the higher cost. Considering market efficiency, we found that over the study period the farmer’s share of the consumer’s expenditure dropped from 51% to 37% in the case of wheat, while it increased from 24% to 26% in the case of rice. The reverse happened for wholesale and retail margin share, where it increased for wheat and decreased for rice. It is likely that the discipline from foreign suppliers of imported wheat and foreign market opportunities for exported rice may explain the difference in the changes of the distribution of consumer expenditure. Finally, we found that area response elasticity decreased over time from 0.58 to 0.12 for rice and 0.60 to 0.38 for wheat. The lack of response in rice area despite rising prices is attributed to the land limit strictly imposed by the Government of Egypt because of water supply constraint considerations. On the other hand, the lack of response in wheat area despite rising wheat prices may be attributed to the rising competitiveness of Egyptian clover, which is a main feed ingredient for the growing livestock sector.

description: Near a magic twist angle, bilayer graphene transforms from a weakly correlated Fermi liquid to a strongly correlated two-dimensional electron system with properties that are extraordinarily sensitive to carrier density and to controllable environmental factors such as the proximity of nearby gates and twist-angle variation. Among other phenomena magic-angle twisted bilayer graphene hosts superconductivity, interaction induced insulating states, magnetism, electronic nematicity, linear-in-T low-temperature resistivity, and quantized anomalous Hall states. We highlight some key research results in this field, point to important questions that remain open, and comment on the place of magic angle twisted bilayer graphene in the strongly correlated quantum matter world.

description: Incentive-based programs to reduce deforestation are expected to play an increasingly important role in global efforts to protect ecosystems and sequester carbon but their environmental effectiveness is not clear. We investigate program effectiveness and slippage in the context of Mexico's national payments for hydrological services program, which pays private and communal landowners to maintain forest cover on enrolled lands. To measure program impacts, we use matched controls drawn from the program applicant pool to establish counterfactual deforestation rates in the absence of payments. We find statistically significant but small to moderate avoided deforestation impacts. To examine slippage of deforestation to nonenrolled lands, we develop a model of household land allocation to agriculture or forest in which some households are credit-constrained. We illustrate that payments for forest conservation may result in slippage due to substitution, resulting in increased deforestation on other parcels belonging to program recipients, or due to output price effects, resulting in increased deforestation within markets where there are high levels of program participation. Our data show evidence consistent with slippage through both mechanisms. This suggests that incentive-based mechanisms can work to prevent deforestation but that avoided deforestation should be accounted for at a regional or national level in international schemes to reduce carbon emissions from deforestation and forest degradation.

description: The physics of foams and emulsions has traditionally been studied using bulk foam/emulsion tests and single film platforms such as the Scheludko cell. Recently there has been a renewed interest in a third class of techniques that we term as single bubble/drop tests, which employ isolated whole bubbles and drops to probe the characteristics of foams and emulsions. Single bubble and drop techniques provide a convenient framework for investigating a number of important characteristics of foams and emulsions, including the rheology, stabilization mechanisms, and rupture dynamics. In this review we provide a comprehensive discussion of the various single bubble/drop platforms and the associated experimental measurement protocols including the construction of coalescence time distributions, visualization of the thin film profiles and characterization of the interfacial rheological properties. Subsequently, we summarize the recent developments in foam and emulsion science with a focus on the results obtained through single bubble/drop techniques. We conclude the review by presenting important venues for future research.

description: We study the consequences of poverty alleviation programs for environmental degradation. We exploit the community-level eligibility discontinuity for a conditional cash transfer program in Mexico to identify the impacts of income increases on deforestation, and use the program’s initial randomized rollout to explore household responses. We find that additional income increases demand for resource-intensive goods. The corresponding production response and deforestation increase is more detectable in communities with poor road infrastructure. These results are consistent with the idea that better access to markets disperses environmental harm and the full effects of treatment can only be observed where poor infrastructure localizes them.
Conifer terpene synthases : functions in induced plant defense, phylogenetic analyses, & molecular modeling
Creators: name: Martin, Diane Marie
Publisher: name: University of British Columbia
Year: 2009

description: Terpenes and terpene biosynthesis play major roles in conifer secondary metabolism. Oleoresin, a combination of monoterpenes, sesquiterpenes and diterpenes, is produced by conifers in copious quantities and stored in specialized anatomical structures. These chemicals serve as toxic protectants and mechanical barriers against invading herbivores and pathogens. Norway spruce, Picea abies, is capable of constitutive and inducible terpenebased defenses. Following insect attack or biological elicitation, Norway spruce is induced to form traumatic resin ducts. The studies presented here describe the complex changes induced after methyl jasmonate (MeJA) treatment in this species. Terpene defenses are characterized in a tissue specific manner on anatomical, chemical, biochemical, and molecular levels. The formation of traumatic resin ducts in the developing xylem is initiated after MeJA treatment. Similarly, the accumulation of monoterpenes in both bark and wood and the accumulation of diterpenes in wood begin rapidly after MeJA treatment. Terpene accumulation is preceded temporally by the increase in GGPP synthase, monoterpene synthase (mono-TPS) and diterpene synthase (di-TPS) activities in wood. Mono-TPS and di-TPS transcripts increase in abundance in stem tissue and mono-TPS transcripts increase in foliage following MeJA treatment. MeJA treatment also induces the release of large amounts of volatile oxygenated monoterpenes and sesquiterpenes, compounds that are not emitted from untreated control plants. This emission of volatile terpenes coincides with a two-fold accumulation on terpenes in foliage and a five-fold increase in TPS activities. Ten Norway spruce TPS genes, involved in these constitutive and inducible defenses, were cloned, functionally expressed and characterized. This suite of TPS contains members of the mono-TPS, sesqui-TPS and di-TPS biochemical classes including several of previously not characterized functions. Furthermore, these TPS have provided a new basis to re-examine the phylogeny of the gymnosperm TPS-d subfamily and the TPS family overall. A model of gymnosperm TPS evolution is discussed as are some striking parallels between gymnosperm and angiosperm TPS evolution.

description: The importance of nonprofit organizations such as rural development organizations, farmers associations and common initiative groups as drivers of change in rural areas has been generally recognized in the economics of nonprofit organizations. While the economic theories attempt to explain the formation and functioning of nonprofit organizations, the targeting and outreach performance of these organizations has received little attention and at best is empirically divergent. Using the example of a nonprofit rural development organization in North West Cameroon, this paper analyzes the relative poverty of beneficiaries and non beneficiaries of its small scale fish farming program as a proxy for targeting efficiency. Poverty is measured through multiple indicators as well as household incomes. The results show that the nonprofit organization did a commendable job in serving poor communities, although its self targeting approach led to a disproportionately higher share of beneficiaries from the moderately poor and better-off terciles than from the poorest. Beneficiaries also had higher asset values and incomes than nonbeneficiaries, although the contribution of the fish farming activity to these was insignificant. This means that these households were already better-off prior to the program and not necessarily as a consequence of service delivery. The paper concludes with the need for relative poverty assessments prior to service delivery for improved targeting and outreach performance, while considering the additional costs involved.

description: Galactic ultra compact binaries are expected to be the dominant source of gravitational waves in the milli-Hertz frequency band. Of the tens of millions of galactic binaries with periods shorter than an hour, it is estimated that a few tens of thousand will be resolved by the future Laser Interferometer Space Antenna (LISA). The unresolved remainder will be the main source of ``noise'' between 1-3 milli-Hertz. Typical galactic binaries are millions of years from merger, and consequently their signals will persist for the the duration of the LISA mission. Extracting tens of thousands of overlapping galactic signals and characterizing the unresolved component is a central challenge in LISA data analysis, and a key contribution to arriving at a global solution that simultaneously fits for all signals in the band. Here we present an end-to-end analysis pipeline for galactic binaries that uses trans-dimensional Bayesian inference to develop a time-evolving catalog of sources as data arrive from the LISA constellation.

description: As a result of a large number of food scandals, societal interest in transparency in the food sector has grown considerably. Deficits have been discovered, which new legal frameworks of the EU and the German legislative body have attempted to address. Hence, the creation of transparency in the production process has been the focus of the legislation. In this context, traceability systems for animal-based foods, for instance, have been established (Regulation (EC) 178/2002). In addition to tracking and tracing, one finds in the public discussion an increasing number of demands for further information, for instance information on food safety, animal and environmental protection and generally for sustainability of the production processes for foods. This is intended as a response to the general call for more transparency or a "gläserne Produktion ". It has not been sufficiently clarified which information about the production process, and thus which level of transparency is actually desired, or can actually be processed, by consumers at the point of sale. This is related to the question of to what extent the demands for more transparency in meat production are influenced by new campaigns of many consumer organisations and NGOs, or whether these actually represent user preferences at the point of sale. In order to analyse this topic from the viewpoint of the consumer, a large-scale empirical study has been conducted. This is intended to determine what transparency expectations, in the form of information on packaged pork, consumers have, using an adaptive conjoint analysis

Description of claw horn lesions and associated risk factors in dairy cattle in the lower Fraser Valley, British Columbia
Creators: name: Bell, Erin Leigh

Year: 2009

description: One of the principal causes of lameness in cattle is claw horn lesions on the hoof, but the extent of the problem within Canada is unknown. My aim was to describe the prevalence of claw horn lesions in dairy cattle from the Fraser Valley of British Columbia and identify farm management and environment factors that are most associated with claw horn lesions in this area. I recorded the number, severity, and location of lesions in the claws of 624 Holstein cows from 20 herds during hoof trimming. Lesions were found in cows from all herds. The mean (± S.D.) herd prevalence of cows with at least one claw horn lesion was 85.7 ± 13.8%. Within the individual cow, I found differences in the number of lesions observed on different claws, with the hind lateral claws containing the most lesions. Cows were at greater risk for claw horn lesions at the beginning of their lactation and older cows were more likely to develop severe lesions. Overall, cows with higher body condition scores were less likely to have claw horn lesions than those with lower scores. Farms with high steps, computer grain feeders, narrow free stalls, shallow bedding, automatic alley scrapers, and flooring imperfections had a higher herd prevalence of claw horn lesions. In conclusion, claw horn lesions affect the majority of dairy cows in the lower Fraser Valley, and the risk of development is related to individual cow factors and farm characteristics.

description: In this paper we build on the ideas presented in previous works for perfectly transferring a quantum state between opposite ends of a spin chain using a fixed Hamiltonian. While all previous studies have concentrated on nearest-neighbor couplings, we demonstrate how to incorporate additional terms in the Hamiltonian by solving an Inverse Eigenvalue Problem. We also explore issues relating to the choice of the eigenvalue spectrum of the Hamiltonian, such as the tolerance to errors and the rate of information transfer.

description: Even in relatively peripheral areas, such as the Portuguese-Spanish border regions, agriculture and food systems have changed greatly in the last decades. Traditional agricultural systems have been declining and some products are no longer appreciated, or even tend to become quantitatively insignificant. Not only are producers ageing but their knowledge and know-how along with the local genetic heritage and biodiversity associated with farming are at risk of disappearing. Local products and markets have been progressively integrated into the larger framework of the global food market. Distributors, restaurant owners and consumers in general rely more and more on exogenous food products, despite the undeniable quality of the existing products and the emerging new urban demand for these products at a larger scale. Recent studies show that there is still room for small-scale production and localized food systems, although a considerable effort needs to be made if they are to be strengthened or re-established. This paper presents a comparative study of both the potential and limitations of traditional local products in the border area of Northern Portugal and the Spanish Province of Salamanca, in Castilla-Léon. It analyzes the types of products, production processes, qualification strategies, as well as the markets and commercialization approaches. The study is based on official published documents and interviews with local producers. Results show that the Portuguese regions are better positioned in terms of number of producers of traditional products, especially the organic products. On the whole, the major difficulties seem to lie in adequately qualifying, promoting and commercializing the products. Besides, co-operation among local agri-food entrepreneurs (in each zone and across the border) is quite feeble and does pose a challenge for the future. In general, localized systems tend to be quite weak, due to the decrease in population and the poor co-ordination among actors and the organization of local supply chains.

description: El sector de la alimentación se enfrenta últimamente a un mercado cada vez más competitivo y más globalizado, donde las diferencias culturales parecen ser un aspecto importante de la adopción y difusión de innovaciones internacionales. Los diferentes grupos culturales difieren en su evaluación de productos, por lo tanto entender las actitudes y comportamientos de los diferentes grupos étnicos puede ser fundamental de cara a conocer la posible aceptación de productos en el mercado. Sobre esta base argumental, este trabajo pretende analizar si la estructura de decisión con respecto a un nuevo alimento varía en su complejidad y en el tipo de beneficios y valores buscados en función del origen étnico del encuestado. Para contrastar estos objetivos se ha planteado un ejercicio en el que se aplica la teoría “means-end chain”, que establece las relaciones entre atributos-consecuencias-valores frente al consumo de un alimento étnico (cous-cous), a través de una entrevista laddering entre dos tipos de origen étnico (español y árabe). Los resultados indican la existencia de una importante dimensión emocional en el consumo del producto analizado, siendo esta dimensión más importante en el grupo de origen árabe, lo que indica que el mayor conocimiento del producto implica una mayor complejidad en el proceso de elección. Asimismo, independientemente de su origen la adopción de este producto viene motivada por el sabor del mismo, el placer que proporciona su consumo y la calidad de vida y seguridad que les proporciona a los consumidores. Sin embargo también se aprecian algunas diferencias, concediendo una mayor importancia al origen geográfico y la identificación cultural el grupo árabe, así como a considerar que con el consumo del cous-cous están cumpliendo con sus obligaciones en relación a su entorno familiar. En el caso de los consumidores de origen español destaca el sentirse más cercano a las nuevas tendencias, más cosmopolita y adquirir un mayor éxito con respecto a su entorno. Todos estos aspectos pueden ayudar a proponer a la oferta alimentaria actuaciones más adecuadas en cada tipo de demandantes cara a conseguir un mejor posicionamiento del producto y en consecuencia, mejores resultados empresariales.

description: The formation of social networks and the evolution of their structures have been of interest to researchers for many decades. We wish to answer questions about network stability, group formation and popularity effects. We propose a latent space model for ranked dynamic networks that can be used to intuitively frame and answer these questions. The well known data collected by Newcomb in the 1950's is very well suited to analyze the formation of a social network. We applied our model to this data in order to investigate the network stability, what groupings emerge and when they emerge, and how individual popularity is associated with individual stability.

description: The reform of EU agricultural policy set up by Agenda 2000 was intended to develop a competitive, sustainable and multifunctional agriculture, through instruments of both the market and income support policy and the rural development policy. To design strategies and actions while simultaneously considering the multifunctional character of farming and of rural areas, it is necessary to measure the multifunctionality with reference to the sectorial and territorial dimensions. This research represents a methodological contribution to the analyses whose aim it is to describe the multifunctional character of the territory. The availability of data regarding the functions performed by farms, the private or public nature of goods produced and the location of the business, suggested focusing our research on agritourism enterprises at community level. Data was analyzed using the fuzzy clustering algorithm Fanny, which allowed us to test a procedure in order to create a partition in which the communities (statistical units) of each group were functionally similar and geographically close to each other. Furthermore, fuzzy clustering allowed us not only to classify the units into homogeneous groups, but also offered the possibility of identifying the membership degrees of each unit. As to planning all this information is important in designing sectorial and regional development paths differing with regards to each cluster and in identifying any particular intracluster properties at which to target specific projects. The last one is the case of those communities that, having the characteristics of different groups, can be made to migrate towards one cluster rather than another through specific planning, consistent with the objectives of sectorial and territorial policy.

description: Notre communication s’intéresse à de grands espaces agricoles , la PAMPA argentine et l’AMAZONIE brésilienne, qui se caractérisent par la présence de multiples acteurs, agricultures familiales, agroindustriels qui juxtaposent ou associent des modèles différents de développement dans le territoire. Nous proposons ici de discuter à partir d’une revue des travaux sur les SYAL dans quelle mesure cette approche peut être considérée comme clé de lecture pour ces dynamiques spatiales de grande échelle. Quels sont ses atouts et ses limites? Comment penser les processus de spécification des ressources territoriales, de coordination entre acteurs privés et acteurs publiques dans ces régions au profil si particulier.

description: The Quantum Symmetric Simple Exclusion Process (Q-SSEP) is a model for quantum stochastic dynamics of fermions hopping along the edges of a graph with Brownian noisy amplitudes and driven out-of-equilibrium by injection-extraction processes at a few vertices. We present a solution for the invariant probability measure of the one dimensional Q-SSEP in the infinite size limit by constructing the steady correlation functions of the system density matrix and quantum expectation values. These correlation functions code for a rich structure of fluctuating quantum correlations and coherences. Although our construction does not rely on the standard techniques from the theory of integrable systems, it is based on a remarkable interplay between the permutation groups and polynomials. We incidentally point out a possible combinatorial interpretation of the Q-SSEP correlation functions via a surprising connexion with geometric combinatorics and the associahedron polytopes.

description: This paper solves in closed form the system of ODEs ruling the 2D motion of a gravity free double pendulum (GFDP), not subjected to any force. In such a way its movement is governed by the initial conditions only. The relevant strongly non linear ODEs have been put back to hyperelliptic quadratures which, through the Integral Representation Theorem (IRT), are driven to the Lauricella hypergeometric functions. We compute time laws and trajectories of both point masses forming the GFDP in explicit closed form. Suitable sample problems are carried out in order to prove the method effectiveness.

description: La década de los ‘90 marcó el inicio de un periodo de profunda transformación de la vitivinicultura en Argentina, especialmente en la provincia de Mendoza, principal productora de uvas y vinos de este país. La reestructuración tecnológica y organizacional en el sector vitivinícola implicó el paso de un sistema basado en la producción de grandes volúmenes de vino de una calidad estándar para el consumo interno, a un sistema productivo para la producción de vinos de calidad, basados en la identificación varietal, con creciente participación en el mercado mundial de vinos. El dinamismo de la vitivinicultura a nivel provincial traccionó otros tipos de vinos tradicionales –denominados localmente vinos caseros- que encontraron una oportunidad comercial en ciertos nichos de mercado donde se insertan como un producto diferenciado, en los mercados de vinos local y regional. El objetivo de este estudio es analizar los factores que influyeron en la activación del SIAL de vinos caseros y sus efectos sobre el desarrollo rural territorial. Los enfoques teóricos utilizados en el estudio son los de SIAL y de desarrollo rural territorial. El SIAL es un marco de análisis de sistemas productivos locales que nos permite estudiar las articulaciones de pequeñas tramas productivas agroalimentarias con sus territorios, así como también las acciones colectivas que llevaron a la activación de los recursos locales. Mientras que el enfoque del desarrollo rural territorial introduce una mirada del sistema territorial y sus relaciones que abarca no sólo el fenómeno de las transformaciones productivas sino también institucionales que contribuyeron a la activación del SIAL de vinos caseros. Entre sus aportes al desarrollo rural territorial, se destaca la valorización y calificación de estos vinos y el desarrollo de nuevos canales comerciales; las estrategias de pluriactividad desarrolladas a partir de la producción artesanal de vinos y las actividades de agroturismo asociadas; el aumento de los ingresos familiares; el desarrollo de autoempleo; el arraigo de las familias rurales en sus territorios y la disminución de la migración de los jóvenes hacia las áreas urbanas.

description: Distance measurements of supernova remnants (SNRs) are essential and important. Accurate estimates of physical size, dust masses, and some other properties of SNRs depend critically on accurate distance measurements. However, the determination of SNR distances is still a tough task. Red clump stars (RCs) have a long history been used as standard candles. In this work, we take RCs as tracers to determine the distances to a large group of SNRs in the inner disk. We first select RC stars based on the near-infrared (IR) color-magnitude diagram (CMD). Then, the distance to and extinction of RC stars are calculated. To extend the measurable range of distance, we combine near-IR photometric data from the 2MASS survey with the deeper UKIDSS and VVV surveys. With the help of the Gaia parallaxes, we also remove contaminants including dwarfs and giants. Because an SN explosion compresses the surrounding interstellar medium, the SNR region would become denser and exhibit higher extinction than the surroundings. The distance of a SNR is then recognized by the position where the extinction and its gradient is higher than that of the ambient medium. A total of 63 SNRs' distances in the Galactic inner disk are determined and divided into three Levels A, B, and C with decreasing reliability. The distances to 43 SNRs are well determined with reliability A or B. The diameters and dust masses of SNRs are estimated with the obtained distance and extinction.

description: Migratory waterfowl are important to the diets of residents in Canada’s northern communities. Contrary to recreational hunters, indigenous peoples have rights to harvest wildlife for subsistence needs without permits. As a result, migratory waterfowl are an important component of diets of Aboriginal peoples in northern Canada, substituting for expensive beef transported from the south. Wild geese and duck provide many benefits to native people, including improved nutrition and health. In this paper, scaled-down data from global climate models are used in a wildlife model to project potential migratory waterfowl abundance in the Northwest Territories for three future periods up to 2080. The models project potential future harvests of geese and ducks by Aboriginal hunters and the financial and nutritional benefits. It turns out that northern Aboriginal peoples can benefit significantly as a result of climate change that affects migratory waterfowl, but likely at the expense of hunters and recreationists in other regions of North America.

description: Absorption spectra, exciton energy levels and wave functions for solid Ne and Ar have been calculated from first principles using many-body techniques. Electronic band structures of Ne and Ar were calculated using the GW approximation. Exciton states were calculated by diagonalizing an exciton Hamiltonian derived from the particle-hole Green function, whose equation of motion is the Bethe-Salpeter equation. Singlet and triplet exciton series up to n=5 for Ne and n=3 for Ar were obtained. Binding energies and longitudinal-transverse splittings of n=1 excitons are in excellent agreement with experiment. Plots of correlated electron-hole wave functions show that the electron-hole complex is delocalised over roughly 7 a.u. in solid Ar.
