description: Long-only-Indexfonds stehen seit geraumer Zeit unter Verdacht, für die Preisanstiege an landwirtschaftlichen Warenterminmärkten, insbesondere für Getreide, verantwortlich zu sein. Diese Arbeit untersucht anhand partieller Gleichgewichtskonzepte die langfristige Marktwirkung von Long-only-Indexfonds. Die Analyse zeigt, dass Long-only-Indexfonds keineswegs Preise treiben, sondern stabilisieren. Der Markteintritt von Long-only-Indexfonds verringert die Risikoprämie. Landwirte können sich zu geringeren Kosten am Warenterminmarkt absichern. Letzteres fördert die Lagerhaltung und schwächt so saisonale Preisschwankungen am Kassamarkt ab. Der Markteintritt von Long-only-Indexfonds ist somit auch im Interesse der Konsumenten. Lediglich Long-only-Indexfonds selbst profitieren nicht von einem weiteren Markteintritt von Long-only-Indexfonds, da deren Rentabilität negativ korreliert ist mit der Anzahl sich am Warenterminmarkt befindlichen Long-only-Indexfonds. Von einer Regulierung von Long-only-Indexfonds sollte abgesehen werden.

description: In Hungary, the rates of direct payments to farmers under the Common Agricultural Policy for the period 2014-2020, the distribution of these payments, and ultimately their impacts on farming decisions, will depend on the combination of mandatory and optional Pillar I support schemes to be introduced in 2015. This paper presents estimations of the structural impact of six new support policy option mixes (scenarios) compared to 2013 (baseline), and discusses the policy implications in terms of the capping of direct payments versus the possible introduction of the Redistributive Payment in particular. The calculations of direct payment rates and the distribution of these payments were based on the database of the Hungarian Agricultural and Rural Development Agency for 2011, and the moving averages of the descriptive parameters of farms were obtained from the Farm Accountancy Data Network. To assess the structural impacts an agent-based simulation model was developed. Decisions were modelled at the micro-level and macro-outcomes were modelled as the consequences of these micro-level decisions. From an economic point of view, the Redistributive Payment would have no real advantage over the capping of direct payments in Hungary as the Redistributive Payment would benefit only farms of relatively small size and would shift funding away from even mid-sized family farms. Furthermore a top-up on the first 30 hectares would neither cause any significant structural changes in arable production, nor in livestock farming. In terms of employment and rural livelihoods, however, the picture might be more nuanced.

description: Recently new data from the Cosmo-LEP project appeared, this time from DELPHI detector. They essentially confirm the findings reported some time ago by ALEPH, namely the appearence of bundles of muons with unexpectedly high multiplicities, which so far cannot be accounted by present day models. We argue, using arguments presented by us some time ago, that this phenomenon could be regarded as one more candidate for the presence in the flux of cosmic rays entering the Earth's atmosphere from outer space nuggets od Strange Quark Matter (SQM) in form of so called strangelets.

description: The article analyses problems of the determination of the fair value of a multifunctional family farm using the method of discounted cash flow, presents a model of determination of the fair value of a multifunctional family farm and tests it for a selected family farm. The specificity of the cash flows in a multifunctional family farm is related to the cash flows from financial support, different value drivers of the earnings before interests and tax and their calculation methodology, and the value of created public goods and externalities. Two types of discount rates are used to determine the value of a family farm: market-based and social discount rate (SDR). It is appropriate to use the SDR to discount the cash flow of investment, the economic and social benefits whereof are distributed among present and future generations. The stages of the determination of the fair value of a farmer’s farm include: value drivers’ decomposition; differentiation of cash flow and discount rates and measuring value drivers; forecasting cash flow and discount rate value drivers; value drivers’ composition; determination of the terminal value; cash flow discounting.

description: Van der Waals heterostructures composed of transition metal dichalcogenide monolayers (TMDs) are characterized by their truly rich excitonic properties which are determined by their structural, geometric and electronic properties: In contrast to pure monolayers, electrons and holes can be hosted in different materials, resulting in highly tunable dipolar manyparticle complexes. However, for genuine spatially indirect excitons, the dipolar nature is usually accompanied by a notable quenching of the exciton oscillator strength. Via electric and magnetic field dependent measurements, we demonstrate, that a slightly biased pristine bilayer MoS$_2$ hosts strongly dipolar excitons, which preserve a strong oscillator strength. We scrutinize their giant dipole moment, and shed further light on their orbital- and valley physics via bias-dependent magnetic field measurements.

description: We present a systematic study of the spin and charge dynamics of copper oxide superconductors as a function of carrier concentration $x$. Our results portray a coherent physical picture, which reveals a quantum critical point at optimum doping ($x=x_{opt}$), and the formation of an inhomogeneous glassy state at $x < x_{opt}$. This mechanism is argued to arise as an intrinsic property of doped Mott insulators, and therefore to be largely independent of material quality and level of disorder.

description: We show that a connection can be recovered up to gauge from source-to-solution type data associated with the Yang-Mills equations in the four dimensional Minkowski space. Our proof analyzes the principal symbols of waves generated by suitable nonlinear interactions and reduces the inversion to a broken non-abelian light ray transform. The principal symbol analysis of the interaction is based on a delicate calculation that involves the structure of the Lie algebra under consideration and the final result holds for any compact Lie group.

Then, we develop a convergence analysis of GDP per capita PPS (Purchasing Power Parity) conditioned to Common Agricultural Policy (CAP) funds, in order to understand the role of the introduction of the CAP in the convergence of Hungarian rural areas. We find increasing divergence both within Hungarian NUTS 3 regions and between the eastern EU MS NUTS 3 regions, especially after Hungary joined the EU; a limited contribution of the CAP to the catching up of rural areas; and persisting difficulties of working with lacking rural disaggregated statistics.

description: We consider an exactly solvable discretisation of the radial Schrödinger equation of the hydrogen atom with l=0. We first examine direct solutions of the finite difference equation and remark that the solutions can be analytically continued entire functions. A recursive expression for the coefficients in the solution is obtained. The next step is to identify the related three-term recursion relation for Pollaczek polynomials. One-to-one correspondence between the spectral and position representations facilitates the evaluation of Pollaczek polynomials corresponding to the discrete spectrum. Finally, we obtain two alternative and explicit expressions for the solutions of the original difference equation.

The k-interchange-constrained diameter of a transit network: A connectedness indicator that accounts for travel convenience

Year: 2020
Subjects: subject: Data Structures and Algorithms (cs.DS)

description: We study two variants of the shortest path problem. Given an integer k, the k-color-constrained and the k-interchange-constrained shortest path problems, respectively seek a shortest path that uses no more than k colors and one that makes no more than k - 1 alternations of colors. We show that the former problem is NP-hard, when the latter is tractable. The study of these problems is motivated by some limitations in the use of diameter-based metrics to evaluate the topological structure of transit networks. We notably show that indicators such as the diameter or directness of a transit network fail to adequately account for travel convenience in measuring the connectivity of a network and propose a new network indicator, based on solving the k-interchange-constrained shortest path problem, that aims at alleviating these limitations.

description: Objectives: Machine learning models predicting treatment outcomes for individual patients may yield high clinical utility. However, few studies tested the utility of easy to acquire and low-cost sociodemographic and clinical data. In previous work, we reported significant predictions still insufficient for immediate clinical use in a sample with broad diagnostic spectrum. We here examined whether predictions will improve in a diagnostically more homogeneous yet large and naturalistic obsessive-compulsive disorder (OCD) sample. Methods: We used sociodemographic and clinical data routinely acquired during CBT treatment of n = 533 OCD subjects in a specialized outpatient clinic. Results: Remission was predicted with 65% (p = 0.001) balanced accuracy on unseen data for the best model. Higher OCD symptom severity predicted non-remission, while higher age of onset of first OCD symptoms and higher socioeconomic status predicted remission. For dimensional change, prediction achieved r = 0.31 (p = 0.001) between predicted and actual values. Conclusions: The comparison with our previous work suggests that predictions within a diagnostically homogeneous sample, here OCD, are not per se superior to a more diverse sample including several diagnostic groups. Using refined psychological predictors associated with disorder etiology and maintenance or adding further data modalities as neuroimaging or ecological momentary assessments are promising in order to further increase prediction accuracy.
Behavioral analysis of memory in Caenorhabditis elegans
Creators: name: Rose, Jacqueline Kyoko
Publisher: name: University of British Columbia
Year: 2009

description: Memory has been the focus of much research for more than 100 years. The earliest documented memory experiments were published by Hermann Ebbinghaus in 1885. In the current studies I investigated parameters affecting memory for habituation in the nematode Caenorhabditis elegans and determined several cellular mechanisms that underlie the behavioral expression of memory. I found that long-term memory for habituation requires a distributed training protocol. I confirmed the generally accepted view that mechanisms of memory consolidation occur after each training trial by showing that protein synthesis inhibition delivered after every training trial effectively blocked long-term memory. Glutamate has been postulated to play an important cellular role in memory consolidation; the findings of these studies confirm that long-term memory for habituation in C. elegans does not occur i f glutamate transmission is compromised. I found that GLR-1 receptor activation is necessary for formation of long-term memory. Further, using a GFP transgenic strain to measure GLR-1 expression, I observed a significant decrease in GLR-1 24 hours after distributed training thus providing a putative mechanism for memory. I examined the permanence of this glutamate dependent long-term memory for habituation by inhibiting protein synthesis during memory reconsolidation and found that this effectively erased the earlier consolidated memory. Finally, I examined memory at an earlier time point (12 hours instead of 24 hours) and found that 12-hour memory can occur in the absence of 24-hour long-term memory and that 12-hour memory does not rely on distributed training, protein synthesis or glutamate transmission. My results showed that both a massed training protocol and a distributed training protocol produce memory 12 hours following training. Memory 12 hours after massed training is mediated by a different mechanism than memory 12 hours after distributed training. For the purposes of this dissertation, memory types are considered distinct when they appear to rely on separate genes and/or mechanisms. Thus in this research, I have dissected apart at least three distinct forms of memory. Together these studies further our understanding of conditions required for memory to occur, and the mechanisms upon which memory relies.
Many-body Dynamics with Time-dependent Interaction

description: Recent advances in optical Feshbach resonance technique have enabled the experimental investigation of atomic gases with time-dependent interaction. In this work, we study the many-body dynamics of weakly interacting bosons subject with an arbitrary time varying scattering length. By employing a variational ansatz, we derive an effective Hamiltonian that governs the dynamics of thermal particles. Crucially, we show that there exists a hidden symmetry in this Hamiltonian that can map the many-body dynamics to the precession of an SU(1,1) "spin". As a demonstration, we calculate the situation where the scattering length is sinusoidally modulated. We show that the non-compactness of the SU(1,1) group naturally leads to solutions with exponentially growth of Bogoliubov modes and causes instabilities.

description: Public perceptions of plant genetic engineering are of increasing research interest. Although within the current debate on the cultivation of genetically modified plants, many related ethical, political and economic issues need specific consideration, young students’ views on this socio-scientific issue are largely unexplored. Therefore, our current analysis focussed on perceptions of Bavarian 10th graders (N=572) with regard to their hopes and fears in the context of plant genetic engineering. By applying a mixed-methods approach, students rated their individual hopes and fears on a 4-point Likert-scale (quantitative part) and gave a written statement about their individual associations (qualitative part): Hereby, hopes scored much higher than fears (medium effect). The subsequent categorisation of qualitative data resulted in five categories for hopes and four categories for fears. Hopes were mainly associated with economic or ecological aspects as well as with the overall fight against world hunger. Fears dealt mainly with negative consequences on human health and the fate of the environment. Additionally, subjective and objective knowledge were analysed for their influence on students’ perceptions. Subjective knowledge had a significant influence on hopes, objective knowledge did not. This background information is relevant for the age-appropriate preparation of biology lessons: Hopes and fears need to be specifically addressed in order to optimise educational efforts and to support students to become responsible citizens.

description: Most asymptotic results for robust estimates rely on regularity conditions that are difficult to verify in practice. Moreover, these results apply to fixed distribution functions. In the robustness context the distribution of the data remains largely unspecified and hence results that hold uniformly over a set of possible distribution functions are of theoretical and practical interest. Also, it is desirable to be able to determine the size of the set of distribution functions where the uniform properties hold. In this paper we study the problem of obtaining verifiable regularity conditions that suffice to yield uniform consistency and uniform asymptotic normality for location robust estimates when the scale of the errors is unknown. We study M-location estimates calculated with an S-scale and we obtain uniform asymptotic results over contamination neighborhoods. Moreover, we show how to calculate the maximum size of the contamination neighborhoods where these uniform results hold. There is a trade-off between the size of these neighborhoods and the breakdown point of the scale estimate.

description: The main purpose of this study is to provide an overview of the export growth trends in the Hungarian agri-food sector over the last decade and to identify the obstacles hindering the sector’s development. We used constant market share analysis to break down into components the changes in export growth. Almost without exception, the increasing market size accounted for most of the export growth to 14 countries. The commodity (market composition) and competitiveness effects produced varied results and were not so positive. This shows that the Hungarian export structure was less adaptive to changes in demand in the target export markets. There were positive examples however, such as Italy and Slovakia, where the competitiveness effect explained 82 and 64 per cent respectively of the Hungarian export growth. In Romania almost one third of the total Hungarian agri-food export growth was explained by the improved competitiveness. The negative examples are numerous; the most important is the trade relations with Poland where the competitiveness effect almost halved the measured export growth potential. By analysing the price and quality competitiveness of the cereal and oilseed commodities with unit value calculations we could show that the market position of these relatively lower-priced products could be improved.

description: We present a calculation of the Vector Form Factor at the next-to-leading order in the 1/N_C expansion, within the framework of Resonance Chiral Theory. The calculation is performed in the chiral limit, and with two dynamical quark flavours. The ultraviolet behaviour of quantum loops involving virtual resonance propagators is analyzed, together with the kind of counterterms needed in the renormalization procedure. Using the lowest-order equations of motion, we show that only a few combinations of local couplings appear in the final result. The low-energy limit of our calculation reproduces the standard Chiral Perturbation Theory formula, allowing us to determine the resonance contribution to the chiral low-energy couplings, at the next-to-leading order in 1/N_C, keeping a full control of their renormalization scale dependence.

description: This paper attempts to explain the terms of trade adjustment and the process of capital accumulation in a monetary model of sectoral interlinkage under rational expectation. The paper utilises a very standard dual economy framework in which industry and agriculture are two distinct sectors of production. Agriculture production is supply constrained. This may arise due to fixed endowment of land, weather condition etc. On the other hand, employment and output in the industrial sector are determined on the basis of profit maximisation in the presence of wage indexation. The asset structure of the economy includes the stock of primary commodities as one form of asset holding. Since the stock of agricultural commodities is one of the financial assets, its demand is subject to speculation which may entail fluctuating agricultural prices. Many factors have effects on fluctuating agricultural prices. These include monetary shock, parametric changes in agricultural production, changes in government expenditure etc. In this paper we have discussed the comparative static effects of parametric changes of these factors. The paper shows that the short run and long run effects of any particular shock are quite different, not only quantitatively, but also qualitatively. Accordingly, the policy message of the paper is that the short run response may not be a reliable guide to the design of policy.

description: The emergence of AI technologies opens up new business opportunities but requires many players along the entire value chain. This work analyses the ecosystem of an automated, AI-based decision-making platform for safety-critical industrial areas such as automated driving, mixed-criticality applications or human-robot collaboration. First, the technical foundation is presented based on its problem formulation. Currently, deep learning methods as a discipline of sub-symbolic artificial intelligence lack transparency and explainability. Hence, an innovative concept for a certified inference framework in the context of safety-critical applications is proposed. The framework comprises an embedded hardware platform utilising recent findings in accelerating neural networks and a software ecosystem to decrease the risk of systematic errors during training. A comprehensive analysis of the entrepreneurial environment based on patent applications and investments in AI technologies concludes a promising $67 billion market for highly automated driving by 2020 and an $18 billion market opportunity by 2022 in the area of edge computing. Within these sectors, automated decision-making systems will demand a certified platform to ensure standard conformity and compliance. Another vital part of the work is the analysis of the business idea under three aspects, namely ecosystem, value proposition and value chains. The work identifies and investigates the stakeholder's interdependencies within the AI ecosystem using a specific framework. Moreover, the innovation potential of the proposed solution among a defined set of product criteria is developed, and the relation to existing value chains is discussed. The analysis concludes that neglecting the ecosystem of the core product most likely limits the full potential of this business idea in the field of AI.

description: Abstract

The integration of Artificial Intelligence (AI) in English as a Foreign Language (EFL) classroom has emerged as a transformative approach to teaching and learning. This study aims to explore English teachers' perceptions, practices, and the pedagogical use of AI in EFL instruction in Nepal. This research employed a quantitative research design. A cross-sectional survey design was adopted to collect data from a representative sample of English teachers. The study findings reveal a growing yet moderate adoption of AI tools such as chatbots, virtual tutors, adaptive learning platforms, and automated feedback systems in ELT classrooms. These tools were found to enhance personalized learning, foster learner autonomy, and accommodate diverse learning strategies in EFL classroom. However, their utilization varies due to factors such as infrastructure limitations, insufficient training, and unequal access to resources. English teachers reported moderate engagement with AI for tasks like creating presentations, developing test items, and organizing instructional materials, reflecting both the potential and challenges of integrating AI into routine pedagogical practices.  Findings highlight that AI-driven platforms like Grammarly, ChatGPT, and Duolingo offer innovative solutions for English language teaching, providing real-time feedback, improving writing skills, and gamifying learning experiences. Despite these advancements, challenges such as technical barriers, data reliability, and teacher preparedness persist. The study underscores the need for targeted professional development programs, enhanced institutional support, and equitable access to AI tools to maximize their impact on English language teaching.

description: India has witnessed fairly high economic growth since economic liberalisation started in 1991. However, agriculture has remained excluded from the growth experienced in other economic sectors. This growth paradox has serious implications for the agricultural land use pattern. This study uses the Environmental Kuznets Curve hypothesis to examine the impact of agricultural technology and economic development on agricultural land expansion in India. Panel data regression is performed on an unbalanced sample covering information from 25 Indian states for the period 1990 to 2008. Our results suggest a nonlinear (N shaped) relationship between agricultural land expansion and Net State Domestic Product (NSDP) per capita. Two incomes turning points, showing the level of NSDP per capita at which inflection between agricultural land expansion and NSDP per capita takes place, occur at INR 20986.14 and INR 42855.10 respectively. We find mixed results as far as the impact of technological variables on agricultural land expansion is concerned. The study concludes that rapid economic growth in the post liberalisation period has failed to reverse agricultural land expansion in India.

description: En los ultimos anos, la relacion que se establece entre el capital social y el desarrollo economico de las areas rurales ha despertado un creciente interes en la literatura economica. La principal hipotesis es que aquellas comunidades con mayores niveles de capital social tienen unos niveles de desarrollo economico mayor. El establecimiento de redes sociales, formales e informales, es el canal a traves del cual se vehicula la transmision del capital social. El objetivo del presente articulo es analizer la incidencia del capital social en el desarrollo de la actividad de agroturismo. El estudio descansa principalmente en una perspectiva funcional del capital social, si bien considera los efectos de los elementos intangibles asociados a la estructura del sistema social (perspectiva normatica o cultural). En nuestra aproximacion empirica, hemos considerado de gran utilidad las aportaciones de la Teoria de los Actores Sociales-Actor Network Theory-(ANT) para detectar, en el caso de la actividad agroturistica, el nivel de centralidad o importancia de los diferentes actores que configuran tales redes, asi como las externalidades que generan las mismas. Este enfoque permite proponer actuaciones de politica ajustadas con mayor precision a las caracteristicas especificas de las diferentes fases que constituyen el ciclo de vida de la actividad...In the recent years, there is an increasing research focusing on the relation between social capital and economic development in rural areas. The main hypothesis is that communities with higher levels of social capital have a better level of economic development. Social capital has to be understood as emanating from formal and informal social networks. The objective of this paper is to analyze, in the case of agritourism, the incidence of social capital. Using an eclectic approach of social capital (the functional and the cultural approach) and considering also, the Actor Network Theory we analyzed the centrality's level of the different actors involved on agritourism social networks and also the existence and relevance of networks externalities. This approach allows us to propose more accurately specific political measures according to different phases of the agritourism life cycle.

Grammatical possession in Nuu-chah-nulth
Creators: name: Ravinski, Christine
Publisher: name: University of British Columbia

description: The goal of this thesis is to provide a syntactic analysis of the possessive constructions in NCN, a Southern Wakashan language. This thesis adopts a broadly minimalist perspective (Chomsky 1995) and draws on primary data from native speakers intuitions in addition to published sources. Elicited data come mainly from speakers of the Ahousaht dialect, which is spoken on Flores Island, British Columbia. I discuss three types of possessive constructions: (i) possessed DPs (ii) possessed nominal predicates (iii) possessor raising The third type, possessor raising, is of special interest: A possessive marker referring to a possessed subject DP can attach to that subject's predicate. Subject agreement on the predicate then indexes the possessor, not the possessed subject. Unlike in other types of possession, the possessor and its possessum do not form a single constituent. In contrast to parallel structures cross-linguistically, Nuu-chah-nulth possessor raising can occur only from possessed subjects, but it is otherwise unrestricted by possessor or predicate type. I propose for Nuu-chah-nulth that the possessive morpheme corresponds to a possessive head in the functional architecture of either the DP or clausal domain. Both the Possessive Phrase and a possessor DP are associated with a possessive feature. Where the possessive marker is generated above a possessed subject DP, the possessor must raise out of it in order to check this feature. I furthermore adopt the theory of multiple feature checking (Ura 1996), such that the possessor DP may be associated with both a possessive and a set of agreement () features. This allows the possessor to raise further, and check its agreement features with the head that hosts subject inflection. By occupying this higher position the possessor determines inflection structurally, without being directly linked to the external argument of the predicate. This analysis suggests that the notion of "subject" is split between at least two syntactic positions. Evidence illustrating clear subject-object asymmetries as well as data suggesting A-movement of the possessor supports a configurational, rather than discourse-driven, view of Nuu-chah-nulth grammar.

description: We study the effects of a beyond-Horndeski theory of modified gravity in the interior of a population II star. We consider a simple phenomenological model of a $1.1M_{\odot}$ star that has left the main sequence, has a thin Hydrogen burning shell with a partially degenerate isothermal core, surrounded by a radiative envelope having two regions of distinct opacities. Using suitable matching conditions at the two internal boundaries, a numerical analysis of the resulting stellar equations in modified gravity is carried out. While overall, gravity may be weakened, resulting in a decrease of the luminosity and an increase of the radius of the star, these effects are reversed near the core. It is suggested how the model, within its limitations, can yield a bound on the modified gravity parameter.
