description: In recent years, the economic viability of established broad leaf crops has deteriorated, in some cases considerably -above all rapeseed and sugarbeet, for which important crop protection products are no longer available. Herbicide resistance is also increasing in cereals, so more diverse crop rotations -especially with summer crops -are of increasing importance. Against this background, the prospects for soybean cultivation in Germany are being investigated. As an additional leaf crop, soybeans could play an important role in crop rotations in the future -at least south of a line of the A2 highway. Where crop rotations need to be extended and soybeans are possible, they are superior to native legumes and offer opportunities as a sought-after GMO-free feed. Case studies were used to analyze the economic viability of soybeans compared to established crops in selected regions. In southern Germany, climatic and market conditions are already so positive that soybeans are economically attractive without subsidies. In the more northern regions, conditions are generally still somewhat worse, so that soybeans are often not yet competitive there. The potential of soybeans for a healthier crop rotation can only be realized on an area-wide basis if the framework conditions for cultivation improve. A major reason for the current low profitability of soybeans is the high seed cost of about 300 €/ha. Due to the lack of a farm-saved seed regulation as in cereals, farmers have to use certified seed. If they were allowed touse a portion of the harvest for sowing in the following year, variable costs would go down by about 150 €/ha or at least one third. In addition, transport distances to oil mills are a key challenge with the current low volumes. With the help of producer groups, regional harvest volumes could be increased and pooled. This would reduce transaction and transportation costs per ton, allowing higher farm gate prices for soybean growers. Temporary government support for producer groups -including intensified agronomic advice for farmers -could help generate critical mass for the market. Finally, the price potential of GMO-free soybeans has not yet been fully exploited. While imported non-GMO soybeans achieve a premium of about 100 €/t compared to GMO produce, these premiums for domestic commodities are usually about 50€/t below the calculated reference price. Therefore, rising prices and thus better profitability can be expected in the medium term.

description: The energy-momentum vacuum average of a conformally coupled massless scalar field vibrating around a cosmic dislocation (a cosmic string with a dislocation along its axis) is taken as source of the linearized semiclassical Einstein equations. The solution up to first order in the Planck constant is derived. Motion of a test particle is then discussed, showing that under certain circumstances a helical-like dragging effect, with no classical analogue around the cosmic dislocation, is induced by back reaction.

description: Viele Länder haben ihre Exporte während der jüngsten Preisspitzen auf den Weltagrarmärkten beschränkt, um die inländischen Agrarpreise von den Preisentwicklungen auf den internationalen Märkten abzukoppeln. Letztlich sollte damit dem Anstieg der Nahrungsmittelpreisinflation entgegen gewirkt und die Konsumenten vor hohen Nahrungsmittelausgaben geschützt werden. Im Mittelpunkt dieses Policy Briefs stehen die wiederholten Exportverbote für Weizen in Serbien und deren Auswirkungen auf die inländischen Preisentwicklungen für Weizen, Mehl und Brot. In diesem Zusammenhang soll geklärt werden, ob tatsächlich die Endkonsumenten oder andere Akteure entlang der Wertschöpfungskette von den politischen Marktinterventionen profitiert haben.

description: Many countries restricted their exports to world agricultural markets during the most recent price peaks in order to insulate their domestic agricultural prices from price developments in international markets. Their ultimate aim was countering the rise in food price inflation and protecting consumers from high food expenses. This Policy Brief reviews the repeated export bans on wheat in Serbia and their impacts on domestic price developments for wheat, flour and bread and attempts to clarify whether end consumers or players along the added-value chain actually profited from political market interventions.
Bulk phantom fields, increasing warp factors and fermion localisation

description: A bulk phantom scalar field (with negative kinetic energy) in a sine--Gordon type potential is used to generate an exact thick brane solution with an increasing warp factor. It is shown that the growing nature of the warp factor allows the localisation of massive as well as massless spin-half fermions on the brane even without any additional non--gravitational interactions. The exact solutions for the localised massive fermionic modes are presented and discussed. The inclusion of a fermion--scalar Yukawa coupling appears to change the mass spectrum and wave functions of the localised fermion though it does not play the crucial role it did in the case of a decreasing warp factor.

We consider the capability of space-based imaging with a slitless grism: because of the low near-infrared background in space and the high sky-density of high redshift emission line galaxies this makes for a very powerful redshift machine with no moving parts. A small 1m space telescope with a 0.5 degree field of view could measure redshifts for 10^7 galaxies at 0.5

The EuroFIR Food Platform
EuroFIR

description: EuroFIR AISBL has now completing its third year of full operation and still aims to provide food data and supporting tools and products that do possess monopoly type characteristics, and form the basis for underpinning major developments in both research and public policy in a wide number of food and health related areas.

The original seven Strategic Activity Units have now been re-organsied in three main income generating ones: SAU1 - Membership & membership benefits; SAU2 - Bespoke data compileation and consultancy services; and SAU3 - RTD Projects and Tenders. Three additional SAUs have also been retained, which are generally non-income generating or self- supporting: SAU4 - Training and continual professional development and SAU 5 - Stakeholder Engagements, Advisory and Events.

The results for 2011 showing a surplus of 22 k € was a significant improvement in 2010 figures, and was largely due to increased RTD and consultancy income and reduction in office costs (accountancy and internet services). The projected budget plans looked sufficiently favourable for the period 2012-14 based on realistic income levels and operating expenses but any reduction in current income levels would be indicative for a revision of strategy. The focus will be delivering new ordinary members (organsiations and SMEs) from the food and health sector, as well maintaining the RTD income streams.

As part of this process, the involvement of the current members was crucial for the longer- term sustainability and these will be encouraged to be more involved in dissemination and stakeholder engagements, as well as working with EuroFIr AISBL to develop new initiatives. The increased involvement of the Executive Board, not only to monitor and assess the income and operating expenses, but to contribute to the maintenance and improvement of the offerings to members, and also attracting new members and commercial, income- generating projects.

Reasonable expansion of the membership base through increased membership of new ordinary members from a wider food and health area, and expansion through the provision of the products to a wider number of institutions, individuals and third parties, should be expected to provide a sound financial basis for longer-term financial survivability.

description: Es besteht eine erhebliche Gefahr, dass politisch verordnete Markteingriffe, die einem vermeintlichen Versagen der Märkte entgegenwirken sollen, Agrarmärkte nicht besser sondern schlechter funktionieren lassen. Dies gilt einmal mehr für osteuropäische Transformationsländer mit einem eingeschränkt funktionierenden institutionellen Regelwerk. Auf Basis der Ergebnisse verschiedener empirischer Untersuchungen zur Funktionstüchtigkeit osteuropäischer Getreide-, Milch- und Fleischmärkte plädiert der vorliegende Policy Brief nachdrücklich für eine Zurückhaltung mit agrarmarktregulierenden Maßnahmen. Es zeigt sich, dass diese mit hohen gesamtwirtschaftlichen Kosten verbunden sind und ihren populistisch motivierten Zielen sogar entgegenwirken können.

An environmentally induced model of ALS-PDC and gene-environment interactions in neurological disease
Creators: name: Wilson, Jason Murray Blair
Publisher: name: University of British Columbia
Year: 2009

description: The etiology of sporadic neurological diseases is unknown and the complete progression of the diseases remains undefined and poorly understood. Epidemiological studies have linked cycad flour consumption and the development of the neurodegenerative disorder, amyotrophic lateral sclerosis-parkinsonism dementia complex (ALS-PDC) of the Western Pacific. The presumed causal factor(s) is one or more of the toxins contained in washed cycad seed flour. In vivo studies of mice fed washed cycad seeds were tested with a battery of motor, cognitive, and olfactory behavioural measures that illustrated a temporal sequence of deficits correlated to neural cell death in the CNS. In addition, magnetic resonance microscopy (MRM) scans of the brains and spinal cords of cycad treated animals ex vivo showed decreased volumes in the CNS. Epidemiological data also suggest a correlation of ALS-PDC and particular susceptibility genes such as those coding for Apolipoprotein E (ApoE). Allele variations of ApoE have also been associated with genetic susceptibility to Alzheimer's disease, motor neuron diseases including ALS, and may affect the age of onset and disease progression. Initial experiments used both ApoE knock out (KO) mice and their wild-type (WT) counterparts to determine if the ApoE gene affected the level of cycad-induced neurodegeneration. Subsequently, washed cycad flour was fed to mice expressing the human ApoE alleles ApoE2, ApoE3, and ApoE4 and to WT mice. Cycad-fed WT mice developed progressive behavioural deficits including ALS-PDC-like pathological outcomes, while cycad-fed ApoE-KO mice were not significantly affected. Motor tests also revealed that all four groups of mice showed progressive motor deficits, with ApoE2 showing reduced deficits compared to ApoE4 and WT mice. ApoE2 mice also showed decreased pathology based on tyrosine hydroxylase labelling and motor neuron counts compared to other cycad-fed groups. Final studies were conducted to determine if an isolated cycad toxin fed to mice could induce an ALS-PDC phenotype. Mice were fed SG (β-sitosterol β-D-glucoside) as part of their normal diet for 10 weeks. Results showed that the SG feeding was toxic to motor neurons in the lumbar spinal cord. The insights gained from this model will be useful for future prophylaxis and treatment of human neurological diseases.

description: We present the most complete list of mirror pairs of Calabi-Yau complete intersections in toric ambient varieties and develop the methods to solve the topological string and to calculate higher genus amplitudes on these compact Calabi-Yau spaces. These symplectic invariants are used to remove redundancies in examples. The construction of the B-model propagators leads to compatibility conditions, which constrain multi-parameter mirror maps. For K3 fibered Calabi-Yau spaces without reducible fibers we find closed formulas for all genus contributions in the fiber direction from the geometry of the fibration. If the heterotic dual to this geometry is known, the higher genus invariants can be identified with the degeneracies of BPS states contributing to gravitational threshold corrections and all genus checks on string duality in the perturbative regime are accomplished. We find, however, that the BPS degeneracies do not uniquely fix the non-perturbative completion of the heterotic string. For these geometries we can write the topological partition function in terms of the Donaldson-Thomas invariants and we perform a non-trivial check of S-duality in topological strings. We further investigate transitions via collapsing D5 del Pezzo surfaces and the occurrence of free Z2 quotients that lead to a new class of heterotic duals.

The critical environmental and cultural demographic characteristics impacts arelargely neglected in the past studies. To fill the research gap, this article also analysingthe importance of cultural demographic characteristics in choosing conventional and Islamic banks. It is concluded that in considering motives responsible for selecting Islamic banks as preferred institutions, respondent level of understanding about Islamic financial system stands out as being thesignificant one with many other motives based on personal beliefs. The evidence generated in the study did not find an important consideration of the specific social demographic factors in increasing the utilization of services provided by Islamic banks; extent of knowledge plays an important role in selecting Islamic banks as preferred institutions; and there is a high degree of awareness on the part of academicians regarding the advantage of the best regulatory services and role of the Islamic banking system in social and economic growth of Pakistan.

description: The objective of this study is to estimate the cost-effectiveness of KTE-X19 versus standard of care (SoC) in the treatment of relapsed/refractory (R/R) mantle cell lymphoma (MCL) patients from a US healthcare perspective. A three-state partitioned-survival model (pre-progression, post-progression, and death) with a cycle length of 1 month was used to extrapolate progression-free and overall survival (OS) over a lifetime horizon. Due to the long tail of the OS curve, OS was modeled applying a mixture–cure methodology, using the assumption that patients whose disease had not progressed after 5 years experienced long-term remission. Population inputs were derived from the ZUMA-2 trial. This was also the source of KTE-X19 efficacy and safety data, while this data was obtained from the literature for SoC. Costs and resource use inputs were derived from the published literature and publicly available data sources. Health state utilities were derived from the ZUMA-2 trial (NCT02601313), applying the US tariff. Adverse event disutilities were derived from the published literature. Costs and health outcomes were discounted at 3% per year. The model estimated expected life years (LY), quality-adjusted life years (QALY), and total costs for KTE-X19 vs SoC. Deterministic and probabilistic sensitivity analyses were performed. Median survival was 9.71 years for KTE-X19 and 2.13 for SoC. Discounted LYs, QALYs, and lifetime costs were 8.99, 7.39, and $693,832 for KTE-X19 vs 4.47, 3.65, and $574,263 for SoC, respectively. The KTE-X19 vs SoC cost per QALY was $31,985. The most influential model parameter was the utility for patients with long-term remission. At a willingness-to-pay threshold of $150,000 per QALY, the probability that KTE-X19 was cost-effective was 99%. The treatment of R/R MCL with KTE-X19 presents a potentially cost-effective alternative to the current SoC, deriving its value from incremental survival and health-related quality-of-life benefits.

description: Substantial danger exists that politically prescribed market interventions, designed to counter a supposed failure of the markets, will leave markets functioning worse rather than better. This is particularly true of Eastern European transition countries, where institutional regulations function only to a limited extent. Based on the findings of a variety of empirical studies that examine how Eastern European grain, dairy and meat markets are functioning, this policy brief strongly advocates restraint in the introduction of measures to regulate agricultural markets. Such regulations have high macroeconomic costs and may work counter to their objectives, which are designed to have popular appeal.

description: Eine konfluente Zeichnung eines Graphens ist eine Zeichnung, in welcher die Knoten des Graphens als Punkte in der Ebene und die Kanten als glatte Pfade durch ein planares System von Kreuzungen und Bögen dargestellt werden. Als außen-konfluente Zeichnung werden jene konfluente Zeichnungen bezeichnet bei welchen alle Knoten auf der Außenfläche liegen. Schlussendlich ist eine strikte außen-konfluente Zeichnung eine außen-konfluente Zeichnung bei der es keine zwei unterschiedliche Pfade zwischen zwei Knoten gibt und kein Knoten einen Pfad zu sich selbst aufweist. Eppstein et al.(2016) beschrieben auf einem sehr abstrakten Level einen Algorithmus, welcher für einen gegebenen Graphen zusammen mit einer Ordnung der Knoten feststellt ob dieser Graph mit dieser Ordnung eine strikt außen-konfluente Zeichnung besitzt oder nicht. Bisher wurde dieser Algorithmus jedoch noch nicht implementiert. Ein Teil meiner Arbeit ist die Implementierung dieses Algorithmus sowie eine detailierte Beschreibung des Algorithmus. Mit der korrekten Implementierung des Algorithmus war es uns dann möglich zu testen ob unterschiedliche Graphklassen solche Zeichnungen besitzen oder nicht. Ein Ergebnis dieser Auswertung ist, dass bipartite Permutationsgraphen nicht immer eine solche Zeichnung besitzen, obwohl dies unsere Annahme war.
description: A confluent drawing is a drawing of a graph where vertices are presented as points in the plane and edges as smooth paths through a planar system of junctions and arcs. An outerconfluent drawing is a confluent drawing in which all vertices of the graph lie on the boundary of the outer face of the drawing. Furthermore, a strict outerconfluent drawing is an outerconfluent drawing with the additional constraint that there is no self-loop between two vertices and that there exists at most one path between two vertices. Eppstein et al.(2016) abstractly defined an algorithm for checking a given graph together with a vertex order for a strict outerconfluent drawing. However, this algorithm has never been implemented. As part of this thesis the algorithm was implemented and a detailed description of each individual step is presented. With the correct implementation we tried to find different classes of graphs which do or do not obtain strict outerconfluent drawings. One of our results is that bipartite permutation graphs do not obtain strict outerconfluent drawings although this was suspected in a recent paper by Förster et al.(2019).

description: Recently, AlphaZero has achieved landmark results in deep reinforcement learning, by providing a single self-play architecture that learned three different games at super human level. AlphaZero is a large and complicated system with many parameters, and success requires much compute power and fine-tuning. Reproducing results in other games is a challenge, and many researchers are looking for ways to improve results while reducing computational demands. AlphaZero's design is purely based on self-play and makes no use of labeled expert data ordomain specific enhancements; it is designed to learn from scratch. We propose a novel approach to deal with this cold-start problem by employing simple search enhancements at the beginning phase of self-play training, namely Rollout, Rapid Action Value Estimate (RAVE) and dynamically weighted combinations of these with the neural network, and Rolling Horizon Evolutionary Algorithms (RHEA). Our experiments indicate that most of these enhancements improve the performance of their baseline player in three different (small) board games, with especially RAVE based variants playing strongly.

description: This work studies the environmental impacts and economic performances of an Amazonian traditional beef farm, using a production cost and profitability analysis (Matsunaga et al., 1976) and a Life Cycle Assessment Standards Model (ISO 14044, 2006). The results reveal that economic and environmental performances share the same kind of determinants – low productivity of animals and land – which are major problems in Brazilian extensive livestock farms. Better management practices and technical efficiency associated with an “ecological intensification” of the production system could be a “win-win” strategy (Porter, 1991; Porter and van der Linde, 1995) in order to improve both performances.

description: This study provides a literature review of social capital in cooperatives. We integrate the social capital concept with cooperative lifecycle theory and describe the change of cooperative social capital along the lifecycle. We propose that cooperatives in different stages of the lifecycle are featured with different social capital levels. Cooperatives are supposed to enjoy a large stock of social capital in the early stages of the lifecycle. However, the level of social capital in cooperatives exhibits a trend of declining along the development of the organization. The decrease of social capital will lead to an imbalance of the social and economic attribute of cooperatives. The cooperative’s income rights structure must change accordingly. We argue that it is important for cooperatives to strategically maintain and develop the social capital over time. Otherwise, the comparative advantage of the cooperative form may disappear.
Gender and representation : the writings of Puerto Rican authors in the late nineteenth century (1870-1900)
Creators: name: Saldivia-Berglund, Marcela
Publisher: name: University of British Columbia

description: This dissertation examines literary strategies for the representation of gender and its intersections with class and race in selected writings by four Puerto Rican authors, namely, Alejandro Tapia, Salvador Brau, Manuel Zeno Gandia, and Ana Roque. It focuses on the period between the 1870s and 1890s—before the 1898 United States military occupation— because of the crucial socio-political and economic changes that marked the threshold of a distinct Hispanic Creole literary tradition. I propose an interdisciplinary approach that combines social history, cultural studies, social feminism, and literary theory to provide historical depth and enable contextualization of the material conditions in which late nineteenth-century writings were produced. Moreover, there is a lack of literary analyses that examine and compare the narratives of both men and women writers from the late nineteenth century against the backdrop of the island's social history. This research pays attention to the interplay among different kinds of writings at this particular moment in the history of Puerto Rico where a specific discursive formation took shape. Through close readings I demonstrate how these four authors employed literary strategies to represent their respective political and sexual agendas. Liberal men wrote proposals for the moral reform of women of all classes as they believed it was the best way to control reproduction, adultery, concubinage and interracial sex, thus guaranteeing the "whitening" of society and of the labour force. The discourses about moral reforms for women show the gender ideologies prevalent at the time that were inscribed in the national narratives. Tapia's cosmopolitanism and supernatural topics represent the fragmented identity of the colonized subject striving for representation in Spain, and the gender crisis of the late nineteenth century. Brau and Zeno Gandia portray the peasantry as a sick body that represents the social stagnation in which the colony was mired. Roque's fiction proclaims her political ideas regarding the role of women in the cultural nation and attacks extramarital affairs, interracial relations, and women's financial vulnerability. The analysis of gender representation and its interrelations with colonialism, patriarchy, class, and race offers innovative perspectives to interpret the past, and to better understand the dynamics of gender power relations that persist to the present day.
Statistical Mechanics of Interfering Links

description: We consider the statistical mechanics of interfering transmissions in a wireless communications protocol. In this case, a connection between two nodes requires all other nodes within communication distance of the given two nodes to remain quiet on the given channel. This leads to an interesting problem of dimers on a lattice, with a restriction that no two dimers can overlap or be nearest neighbors. We consider both an equilibrium and a non-equilibrium, "greedy" dynamics for the links; the equilibrium properties of the model are found to exhibit an interesting spin glass transition at maximum density on certain lattices, while the greedy construction is related to the problem of random sequential adsorption.

description: Globalisation of food markets pressures agricultural cooperatives to seek growth strategies to safeguard competitiveness and the capacity to maintain services. Farmers as the owners of the cooperative are the principal party to provide investment capital. The availability of member financing is however undermined by structural changes in agriculture. The capital intensity of farming discourages voluntary contributions if farmers do not have incentives to commit capital to the cooperative. Choice experiment is employed to uncover preferences for investment attributes among Finnish milk producers. Results indicate that farmers prefer reserving control rights to members, but they could be incentivised to contribute capital on terms which include capital-based residual rights, low-risk return, and compensate for appreciation of firm value. Policy implications of the findings describe the need to redefine member capital instruments innovatively in growing producer cooperatives.

Similar to O. marchettii, except for light colour of all abdominal segments. Median points band not well separated from the posterior band and of similar size and shape. Apical setae on anal lobes straight, anal lobes always without (never with reduced or colourless) apical taeniate extensions of cuticle. COMMENTS. The species can be separated from O. marchettii thanks to the colour of abdomen, its area of distribution (CENTRAL EUROPE, BELGIUM, GREAT BRITAIN, HUNGARY) and its ecology (O. glabripennis is restricted to lentic waters, O. marchetti lives in running waters). O. glabripennis never has any apical extension of cuticle on anal lobes; specimens with small and colourless taeniate extensions of cuticle (Cranston & Langton 1991) should belong to other species (O. ticinoi for example).

description: The “causative” template heXYiZ in Hebrew is the morphological form of verbs which are usually transitive. I discuss cases in which specific roots give rise to the labile alternation, otherwise unattested in the language. A straightforward analysis is suggested for the majority of cases, based on causative Voice [+D] . This analysis is then extended to account for the labile exceptions, which inform how the idiosyncratic meaning of roots influences syntactic computation.

description: The nature of bosonic excitations in disordered materials has remained elusive due to the difficulties in defining key concepts such as quasi-particles in the presence of disorder. We report on the experimental observation of phonon-polaritons in glasses, including a boson peak (BP), i.e. excess of THz modes over the Debye law. A theoretical framework based on the concept of diffusons is developed to model the broadening linewidth of the polariton due to disorder-induced scattering. It is shown that the scaling of the BP frequency with the diffusion constant of the linewidth strongly correlates with that of the Ioffe-Regel (IR) crossover frequency of the polariton. This result demonstrates the universality of the BP in the low-energy spectra of collective bosonic-like excitations in glasses, well beyond the traditional case of acoustic phonons, and establishes the IR crossover as the fundamental physical mechanism behind the BP.

description: Radiative corrections to neutrino deep inelastic scattering are revisited. One-loop electroweak corrections are re-calculated within the automatic SANC system. Terms with mass singularities are treated including higher order leading logarithmic corrections. Scheme dependence of corrections due to weak interactions is investigated. The results are implemented into the data analysis of the NOMAD experiment. The present theoretical accuracy in description of the process is discussed.

Managerial vision bias and cooperative governance

description: Member and professional CEOs of cooperatives differ regarding their managerial vision toward upstream and downstream projects. We show that the managerial vision bias will cause inefficiency in the project implementation. Cooperatives with member CEOs are extremely upstream-focused because of the cascaded negative vision bias toward the downstream projects. When the downstream activities become more important, cooperatives need to replace the member CEOs by professional CEOs. However, a cooperative with a professional CEO may still be less efficient than an IOF (investor owned firm) if the member-dominated Board of Directors’ negative bias toward the downstream projects is too large. To solve this problem, the cooperative must include outside directors in the board to ease the negative bias of the Board of Directors toward the downstream projects.

Abstract.

We present a benchmark study of surrogate models for impurities embedded into crystalline solids. Using the Korringa-Kohn-Rostoker Green Function method [1], we have built databases of several thousand calculations of single impurities (monomers) embedded into different elemental crystals, as well as magnetic transition metal impurity dimers embedded in the topological insulator Bi2Te3. We predict the converged monomer impurity electron potential and the isotropic exchange interaction of the impurity dimer in the classical Heisenberg model. From these surrogates, we intend to build transferable models for larger systems in the future, which will accelerate the convergence of our DFT codes. The study compares various recent E(3)-equivariant models such as ACE and MACE [2] in terms of performance and reproducible end-to-end workflows.
