description: This project has examined after tax gross margin net present values accruing to Albertawheatf armers under three fertilizer and crop rotation systems; a fixed rotation traditional fertilizer system, a static economic fertilizer decision system within a fixed rotation, and a static economic fertilizer decision system within a dynamic flex-cropping framework. Decision rules appropriate to each system were developed for case farms in three Alberta agro-climatic regions; Medicine Hat, Lethbridge and Olds. The flex-cropping issue is expressed in a dynamic programming framework and incorporates elements not fully explored in previous studies; income taxation, variable input level decisions and stochastically determined moisture conditions and crop prices. Decisions are compared by simulating net present values of after tax gross margins for each system. The traditional system generatedthe lowest net present value, approximately 5 to 17 per cent below the static economic system. Greater improvements, on the order of 14 to 31 per cent above the static economic system, were observed by following dynamic flex-cropping decision rules. Not only did the dynamic flex-cropping decision rules generate superior decision rules regarding mean net present values, the rules were also risk efficient. The probability of low gross margins was minimized in all cases by following the dynamic flex-cropping decision rules. The results of this and related studies indicate that dynamic flex-cropping models are viable for solving crop scheduling problems. The prescriptive power of the model is limited by available data, limitations which reside primarily in the agronomic components. The relationship between spring soil moisture, soil nutrients, and yield must be more clearly defined. This may be accomplished through extensive and long term field trials or through use of emerging biophysical models. Standardization of soil moisture classifications, including method of sampling and depth of measurement, would make field data more adaptable for making fertilizer and recropping decisions. The production functions defining the relationship between spring soil moisture levels and yields are particularly important. These require continued empirical attention. The model developed lends itself readily to extensions such as additional crops,fertilizer inputs, erosion costs and soil degradation issues, financial structure of the farm, and evaluating the influence of government programs. Modern computers with large computational and storage capabilities make the implementation of stochastic dynamic programming methodology a viable farm management tool.

description: We theoretically study the modification of the energy spectrum of long-wavelength acoustic phonons due to the electron-phonon interaction in a three-dimensional topological Weyl semimetal under the influence of quantizing magnetic fields. We find that the dispersion and attenuation of phonons show striking oscillatory behaviors as varying the magnetic field at low temperatures. These oscillations are distinct when the Fermi energy is in different energy regimes. Moreover, the van Hove singularity of the Weyl spectrum can manifest as a transition between different oscillation patterns when increasing the magnetic field. These phonon behaviors could provide testable fingerprints of the Fermi surface morphology and relativistic feature of the Weyl semimetal.

description: We apply spectral methods to compute the OZI-rule suppressed loop-loop correlators in the pseudoscalar meson flavour singlet channel. Using SESAM configurations (obtained with two degenerate sea quark flavours on 16x16x16x32 lattices at beta = 5.6 with standard Wilson action), we find for the first time clear evidence for mass plateau formation in the eta' channel of this theory. As a consequence, we observe a clear signal of a mass gap persistent under chiral extrapolation. This sets the stage for a more realistic two-channel approach, where partially quenched strange quarks would be included, in addition to u, d sea quarks.

description: The objective of the research reported in this paper was to assess current trends in the use of contracts by agricultural producers in the Canadian Prairies and determine the factors affecting farmers’ contracting behaviour. Two surveys – one a mailout and one online that yielded a combined 587 usable responses – were used to gather data pertaining to producers’ use of marketing contracts, production contracts, and technology use agreements (TUAs). It was found that such contracts are used frequently by farmers and generally well‐understood. Farmers also indicated they mostly believe they are fairly treated by contracts, but that contracting firms’ rights are carefully protected by contract terms. Econometric analysis indicated that a farmer’s decision to contract is affected by farm type, the mix of crops grown by the operation, net income including off‐farm income, how long the respondent has been farming, and their level of risk aversion. A second econometric model discovered that a farmer’s previous use of contracts, the amount of the contract that the respondent actually reads, the ease with which a contract can be understood, the fact that producers are not indifferent to the existence of enforcement mechanisms, the presence of a dispute settlement mechanism, whether the contracting firm determines inputs to be used, and the provision of a fieldman exert statistically significant effects on the types of contracts used.

description: Using molecular dynamics simulations, we investigate the effect of uniaxial elastostatic compression on the potential energy, structural relaxation, and mechanical properties of binary glasses. We consider the three-dimensional Kob-Andersen binary mixture, which was initially cooled from the liquid state to the glass phase with a slow rate at zero pressure. The glass was then loaded with a static stress at the annealing temperature during extended time intervals. It is found that the static stress below the yielding point induces large-scale plastic deformation and significant rejuvenation when the annealing temperature is smaller than a fraction of the glass transition temperature. By contrast, aging effects become dominant at sufficiently small values of the static stress and higher annealing temperatures. The mechanical tests after the elastostatic compression have shown that both the elastic modulus and the yield stress decrease in rejuvenated samples, while the opposite trend was observed for relaxed glasses. These results might be useful for the thermomechanical processing of metallic glasses with optimized mechanical properties.

description: A new mechanism for generating neutrino masses without a high-energy mass scale is proposed. The mechanism needs a fundamental mass scale M in the 100-1000 TeV region and a minimal field content beyond the Standard Model one containing a pair of fermion singlets and a pair of weak doublet fermions for each neutrino mass, all of them with a mass of order M. The neutrino mass appears by a multiple seesaw-type tree-level diagram. We provide an explicit model based on supersymmetry and an abelian symmetry which provides the required fermion mass matrix. The mechanism is natural in the context of string theories with a low fundamental scale. Within an explicit example where the abelian symmetry is also responsible for the generation of fermion masses and mixings, we give a hint relating the fermion mass matrices and the weak mixing angle. By assuming the weak-strong couplings unification, one naturally finds $\sin^2 θ_w = 1/4$ at the fundamental scale.

description: Breast cancer is the most commonly occurring cancer in women and the second most common cancer overall. By the age of 80, the estimated risk for breast cancer for women with germline BRCA1 or BRCA2 mutations is around 80%. Genetically engineered BRCA1-deficient mouse models offer a unique opportunity to study the pathogenesis and therapy of triple negative breast cancer. Here we present a newly established Brca1−/−, p53−/− mouse mammary tumor cell line, designated as CST. CST shows prominent features of BRCA1-mutated triple-negative breast cancers including increased motility, high proliferation rate, genome instability and sensitivity to platinum chemotherapy and PARP inhibitors (olaparib, veliparib, rucaparib and talazoparib). Genomic instability of CST cells was confirmed by whole genome sequencing, which also revealed the presence of COSMIC (Catalogue of Somatic Mutations in Cancer) mutation signatures 3 and 8 associated with homologous recombination (HR) deficiency. In vitro sensitivity of CST cells was tested against 11 chemotherapy agents. Tumors derived from orthotopically injected CST-mCherry cells in FVB-GFP mice showed sensitivity to cisplatin, providing a new model to study the cooperation of BRCA1-KO, mCherry-positive tumor cells and the GFP-expressing stromal compartment in therapy resistance and metastasis formation. In summary, we have established CST cells as a new model recapitulating major characteristics of BRCA1-negative breast cancers.

description: We report studies of the Yb$^{3+}$ site distribution in Er$^{3+}$ co-doped upconverting alkaline earth fluoride nanoparticles using high-resolution absorption measurements. Similar to bulk crystals, Yb$^{3+}$ single ion cubic (O$_h$), and preferentially formed clusters are the dominant centres for moderate dopant concentrations. At higher concentrations, and for larger particle sizes, a minority C$_{4v}$(F$^-$) centre is also observed. Furthermore, the behaviour of Yb$^{3+}$ cluster centres, whose primary absorption band is located around 10205 cm$^{-1}$ (in near resonance with 980 nm laser diodes) was studied by tuning the metal cation in the host lattice from Ca$^{2+}{\rightarrow}$Sr$^{2+}{\rightarrow}$Ba$^{2+}$. For co-doped materials, with heterogeneous cluster centres, Er$^{3+}$ upconversion fluorescence was observed upon selective excitation of Yb$^{3+}$, resulting in strong visible emission from $^4$H$_{11/2}$, $^4$S$_{3/2}$ and $^4$F$_{9/2}$ multiplets. By monitoring the Er$^{3+}$ $^4$S$_{3/2}{\rightarrow}^4$I$_{15/2}$ (540 nm) fluorescence, whilst scanning a laser through the wavelength dependent Yb3+ absorption, we obtain an excitation spectrum for these heterogeneous cluster centres. It is demonstrated that the group of Yb$^{3+}$ ions residing near an Er$^{3+}$ ion represent a small subset of the overall Yb$^{3+}$ ensemble and therefore a linear absorption measurement is not necessarily a good indication of the optimum laser pump wavelength.

description: Computing in Memory (CIM) is a computing paradigm to overcome the von Neumann bottleneck of traditional computerarchitectures [1]. A possible implementation uses memristor crossbar arrays, which store information as resistance, toperform parallel vector-matrix multiplication (VMM). In this structure, digital to analog converters (DACs) provide inputvoltages to the crossbar rows where the output currents are then measured by analog to digital converters (ADCs). Therefore,both converter circuits play an important role when optimizing the speed and power consumption in the operation.In this research, we propose a single-ended current-mode ADC, as shown in Fig. 1, which can directly measure the inputcurrent from the memristor array without the need for any transconductance amplifier (TIA), sampling-and-hold circuit, oreven charge integration method that is often used for current measurement [2][3]. This ADC measures single-ended inputand is implemented in pseudo-differential manner to enhance its robustness against noise and disturbance. In this ADC, theinput current is first compared with half of the reference current provided by transistor M5 for the most significant bit (MSB)conversion. Then, the subtracted current enters the differential structure formed by transistor M6-9 where they then convertedinto voltage difference across the 350 Ω load resistance. Data conversion is then performed using an array of current-steeringDAC that operate according to the successive-approximation register (SAR) algorithm. The bias for this ADC isimplemented as cascoded current source and can be used for multiple ADC core circuits. Additionally, the dynamic rangeof the ADC can be tuned by simply changing the reference current IREF biasing transistor M0,1.In this work, a 2x2 CIM array is implemented by using 28 nm CMOS technology. As shown in Fig.2, this chip has the sizeof 1.4 mm2 and consists of the control circuit for memristor interface followed by two ADCs. A RISC-V processor is alsoimplemented to control the circuit and direct access available through a JTAG programming interface. The ADC is designedto have dynamic range of 1.28 mA with 6 bit resolution and can work with speed up to 100 MSps while consuming lessthan 3 mW power from 0.9 V power supply. Each ADC occupies less than 0.005 mm2 area and thus suitable to beimplemented multiple times as column ADCs. These ADCs also have the capability of choosing the source of input eitherfrom memristor array or from external input to make the measurement and characterization process easier.

description: Identifying cancer drivers and actionable mutations is critical for precision oncology. In epithelial ovarian cancer (EOC) the majority of mutations lack biological or clinical validation. We fully characterized 43 lines of Patient-Derived Xenografts (PDXs) and performed copy number analysis and whole exome sequencing of 12 lines derived from naïve, high grade EOCs. Pyrosequencing allowed quantifying mutations in the source tumours. Drug response was assayed on PDX Derived Tumour Cells (PDTCs) and in vivo on PDXs. We identified a PIK3R1W624R variant in PDXs from a high grade serous EOC. Allele frequencies of PIK3R1W624R in all the passaged PDXs and in samples of the source tumour suggested that it was truncal and thus possibly a driver mutation. After inconclusive results in silico analyses, PDTCs and PDXs allowed the showing actionability of PIK3R1W624R and addiction of PIK3R1W624R carrying cells to inhibitors of the PI3K/AKT/mTOR pathway. It is noteworthy that PIK3R1 encodes the p85α regulatory subunit of PI3K, that is very rarely mutated in EOC. The PIK3R1W624R mutation is located in the cSH2 domain of the p85α that has never been involved in oncogenesis. These data show that patient-derived models are irreplaceable in their role of unveiling unpredicted driver and actionable variants in advanced ovarian cancer.

description: Over the last decades and across countries, eating patterns have changed in favour of increasing consumption of food away from home. According to Ando and Modigliani (1957), consumers pass through different stages of a life-cycle with different impacts on demand. The criticism that life-cycle theory neglects generational effects and concentrates only on ageing effects has led to the application of the cohort analysis, which decomposes not only age, but also period and cohort effects. This paper presents the results of a cohort analysis on food-at-home and food-away-fromhome consumption covering 25 years of German consumption data. The results of seemingly unrelated regressions indicate that there are significant age, period and cohort effects on food-at-home and foodaway- from-home expenditures, which are more distinct for food-at-home consumption. This paper also finds evidence for the significant effects of gender, occupation, household composition and region on both expenditure categories. For instance, the effect of being female is negative on both types of expenditures. Moreover, there is a non-linear relationship between household size and both food-at-home and food-away-from-home-consumption. Über Jahrzehnte und Länder hinweg haben sich die Ernährungsgewohnheiten der Verbraucher in Richtung einer Zunahme des Außer-Haus-Verzehrs verändert. Nach Ando und Modigliani (1957) durchlaufen Konsumenten verschiedene Stufen eines Lebenszyklus‘ mit unterschiedlichen Auswirkungen auf die Nachfrage. Da die Lebenszyklustheorie nur Alterseffekte berücksichtigt, wird die Kohortenanalyse eingesetzt, die neben Alterseffekten auch Zeit- und Kohorteneffekte einbezieht. Dieses Papier präsentiert die Ergebnisse einer Kohortenanalyse des Inner- und Außer-Haus- Verzehrs basierend auf 25 Jahre umfassenden Verbrauchsdaten aus Deutschland. Ergebnisse von SURRegressionen zeigen, dass signifikante Alters-, Zeitund Kohorteneffekte des Inner- und des Außer-Haus- Verzehrs in Deutschland vorliegen. Diese Arbeit findet signifikante Unterschiede für beide Ausgabenkategorien nach Geschlecht, Beruf, Haushaltszusammensetzung und Region. So haben Frauen geringere Ausgaben sowohl für den Inner- als auch den Außer- Haus-Verzehr. Außerdem ergibt sich ein nichtlinearer Zusammenhang zwischen der Haushaltsgröße und dem Inner- und Außer-Haus-Verzehr.

description: This paper presents a new approach for relatively accurate brain region of interest (ROI) detection from dynamic susceptibility contrast (DSC) perfusion magnetic resonance (MR) images of a human head with abnormal brain anatomy. Such images produce problems for automatic brain segmentation algorithms, and as a result, poor perfusion ROI detection affects both quantitative measurements and visual assessment of perfusion data. In the proposed approach image segmentation is based on CUSUM filter usage that was adapted to be applicable to process DSC perfusion MR images. The result of segmentation is a binary mask of brain ROI that is generated via usage of brain boundary location. Each point of the boundary between the brain and surrounding tissues is detected as a change-point by CUSUM filter. Proposed adopted CUSUM filter operates by accumulating the deviations between the observed and expected intensities of image points at the time of moving on a trajectory. Motion trajectory is created by the iterative change of movement direction inside the background region in order to reach brain region, and vice versa after boundary crossing. Proposed segmentation approach was evaluated with Dice index comparing obtained results to the reference standard. Manually marked brain region pixels (reference standard), as well as visual inspection of detected with CUSUM filter usage brain ROI, were provided by experienced radiologists. The results showed that proposed approach is suitable to be used for brain ROI detection from DSC perfusion MR images of a human head with abnormal brain anatomy and can, therefore, be applied in the DSC perfusion data analysis.

The resulting equations relate the one- and two-particle Green's function to correlators of up to six particles at four times. As an application we consider continuous-time quantum Monte Carlo simulations in the hybridization expansion, which hitherto suffered from notoriously high noise levels at large Matsubara frequencies. Employing the derived symmetric improved estimators overcomes this problem.

description: Variational wave functions have been a successful tool to investigate the properties of quantum spin liquids. Finding their parent Hamiltonians is of primary interest for the experimental simulation of these strongly correlated phases, and for gathering additional insights on their stability. In this work, we systematically reconstruct approximate spin-chain parent Hamiltonians for Jastrow-Gutzwiller wave functions, which share several features with quantum spin liquid wave-functions in two dimensions. Firstly, we determine the different phases encoded in the parameter space through their correlation functions and entanglement content. Secondly, we apply a recently proposed entanglement-guided method to reconstruct parent Hamiltonians to these states, which constrains the search to operators describing relativistic low-energy field theories - as expected for deconfined phases of gauge theories relevant to quantum spin liquids. The quality of the results is discussed using different quantities and comparing to exactly known parent Hamiltonians at specific points in parameter space. Our findings provide guiding principles for experimental Hamiltonian engineering of this class of states.

description: Nanomechanical resonators have emerged as sensors with exceptional sensitivities. These sensing capabilities open new possibilities in the studies of the thermodynamic properties in condensed matter. Here, we use mechanical sensing as a novel approach to measure the thermal properties of low-dimensional materials. We measure the temperature dependence of both the thermal conductivity and the specific heat capacity of a transition metal dichalcogenide (TMD) monolayer down to cryogenic temperature, something that has not been achieved thus far with a single nanoscale object. These measurements show how heat is transported by phonons in two-dimensional systems. Both the thermal conductivity and the specific heat capacity measurements are consistent with predictions based on first-principles.

description: Generalizing previous work, we give a new analytic solution in Witten's open bosonic string field theory which can describe any open string background. The central idea is to use Riemann surface degenerations as a mechanism for taming OPE singularities. This requires leaving the familiar subalgebra of wedge states with insertions, but the payoff is that the solution makes no assumptions about the reference and target D-brane systems, and is therefore truly general. For example, unlike in previous work, the solution can describe time dependent backgrounds and multiple copies of the reference D-brane within the universal sector. The construction also resolves some subtle issues resulting from associativity anomalies, giving a more complete understanding of the relation between the degrees of freedom of different D-brane systems, and a nonperturbative proof of background independence in classical open bosonic string field theory.

description: Judo was created as a tool for people to develop their minds and bodies in order to achieve what they believe to be success, contributing to society and adapting to their time. Kano empirically noted that several cognitive skills that are fundamental to succeeding in life could be acquired through the practice of judo. In neuroscience, the set of these cognitive skills is called executive functions. The purpose of this research note is to correlate current neuroscientific studies with Jigoro Kano’s empirical findings about the benefits of judo practice for the development of mental skills essential for success in contemporary society. Approaches to the development of executive functions have been the subject of scientific studies in various areas, including their relationship with physical activity. Studies report that the development of executive functions through physical activity is dependent on the type of physical activity performed. The most effective physical activity for the development of executive functions are those that involves complex movements with cognitive demands. Researchers found that martial arts that involves both mind and body and requires a high level of cortical recruitment may be considered a mediator of executive functions, since this training may result in an increased cerebral blood flow to the areas of the brain responsible for executive function. Judo is a method of perfecting the human being, including improving mental skills. Studies have shown that martial arts such as judo, that emphasizes self-control, discipline and character development, are means for develop executive functions.

description: This paper surveys the performance of international capital markets and the literature on measuring international capital mobility. Three main functions of a globally integrated and efficient world capital market provide focal points for the analysis. First, asset-price arbitrage ensures that people in different countries face identical prices for a given asset. Second, to the extent that the usual market failures allow, people in different countries can pool risks to their lifetime consumption profiles. Third, new saving, regardless of its country of origin, is allocated toward the world's most productive investment opportunities. The paper evaluates the international capital market's performance of these roles by studying data on international interest-rate differences, international consumption correlations, international portfolio diversification, and the relations between national saving and investment rates. The conclusion. is that while international capital mobility has increased markedly in the last two decades, international capital movements remain less free than intranational movements, even among the industrial countries.

description: In this paper we discuss some unusual and unsuspected relations between Maxwell, Dirac and the Seiberg-Witten equations. First we investigatethe Maxwell-Dirac equivalence (MDE) of the first kind. Crucial to that proposed equivalence is the possibility of solving for $Ψ$(a representative on a given spinorial frame of a Dirac-Hestenes spinor field (DHSF)) the equation $F=Ψγ_{21} \simΨ$, where F is a given electromagnetic field. Such task is presented in this paper and it permits to clarify some possible objections to the MDE which claims that no MDE may exist, because F has six (real) degrees of freedom and $Ψ$ has eight (real) degrees of freedom. Also, we review the generalized Maxwell equation describing charges and monopoles. The enterprise is worth even if there is no evidence until now for magnetic monopoles, because there are at least two faithful field equations that have the form that equations. One is the generalized Hertz potential field equation associated with Maxwell theory and the other is a (non linear) equation satisfied by the 2-form field, which is part of a representative of a DHSF that solves the Dirac-Hestenes equation for a free electron. This is a new and surprising result, which can also be called MDE of the second kind. It strongly suggests that the electron is a composed system with more elementary "charges" of the electric and magnetic types. Finally, we use the MDE of the first kind together with a reasonable hypothesis to give a derivation of the famous Seiberg-Witten equations on Minkowski spacetime.

description: Degradation of the mechanical integrity of cobalt-based superalloys can occur as the carbide network is progressively oxidised during high temperature service. In this study, a heat-treatment aimed at redistributing the carbides was tested on two similar commercial Co-based superalloys, one with high C content (Co-101) and one with low C content (Stellite-21), to determine its influence on oxidation resistance. It was found that the carbide phases in the lower C-containing alloy could be solutioned more readily than the higher C-containing alloy, enabling the continuity of the carbide network to be reduced. This resulted in a reduced attack of the carbides down the interdendritic channels during oxidation testing, but increased thickness of the oxide overscale.
Charmless Final States and S--D-wave mixing in the $ψ''$

description: The $\ppp = ψ(3770)$ resonance is expected to be mainly $c \bar c(1^3D_1)$, but tensor forces and coupling to charmed particle pairs can mix it with $\pp(2^3S_1)$ and other states. Implications of this mixing for decays of $\ppp$ to non-charmed final states are discussed. (i) The ratio $Γ(\ppp \to γ+ χ_{c2})/ Γ(\ppp \to γ+ χ_{c0})$ is expected to be highly suppressed if $\ppp$ is a pure D-wave state, and is enchanced by mixing. (ii) The expected decay $\pp \to ρπ$ and other ``missing'' modes can appear as corresponding $\ppp$ partial widths, enhanced by a factor depending on the mixing angle. General arguments then suggest a branching ratio of about 1%, give or take a factor of 2, for charmless hadronic decays of $\ppp$. (iii) Enhancements can appear in penguin amplitudes in B decays, $B \to K η'$ branching ratios, and direct CP-violating asymmetries in $B \to K π$ decays.

description: We have measured the ground-state $g$-factor of boronlike argon $^{40}\textrm{Ar}^{13+}$ with a fractional uncertainty of \SI{1.4e-9}{} with a single ion in the newly developed ALPHATRAP double Penning-trap setup. The here obtained value of $g=0.663\,648\,455\,32(93)$ is in agreement with our theoretical prediction of $0.663\,648\,12(58)$. The latter is obtained accounting for quantum electrodynamics, electron correlation, and nuclear effects within the state-of-the-art theoretical methods. Our experimental result distinguishes between existing predictions that are in disagreement, and lays the foundations for an independent determination of the fine-structure constant.

description: CLIFFORD performs various computations in Grassmann and Clifford algebras. It can compute with quaternions, octonions, and matrices with entries in Cl(B) - the Clifford algebra of a vector space V endowed with an arbitrary bilinear form B. Two user-selectable algorithms for Clifford product are implemented: 'cmulNUM' - based on Chevalley's recursive formula, and 'cmulRS' - based on non-recursive Rota-Stein sausage. Grassmann and Clifford bases can be used. Properties of reversion in undotted and dotted wedge bases are discussed.

description: The goal in network state prediction (NSP) is to classify the global state (label) associated with features embedded in a graph. This graph structure encoding feature relationships is the key distinctive aspect of NSP compared to classical supervised learning. NSP arises in various applications: gene expression samples embedded in a protein-protein interaction (PPI) network, temporal snapshots of infrastructure or sensor networks, and fMRI coherence network samples from multiple subjects to name a few. Instances from these domains are typically ``wide'' (more features than samples), and thus, feature sub-selection is required for robust and generalizable prediction. How to best employ the network structure in order to learn succinct connected subgraphs encompassing the most discriminative features becomes a central challenge in NSP. Prior work employs connected subgraph sampling or graph smoothing within optimization frameworks, resulting in either large variance of quality or weak control over the connectivity of selected subgraphs. In this work we propose an optimization framework for discriminative subgraph learning (DSL) which simultaneously enforces (i) sparsity, (ii) connectivity and (iii) high discriminative power of the resulting subgraphs of features. Our optimization algorithm is a single-step solution for the NSP and the associated feature selection problem. It is rooted in the rich literature on maximal-margin optimization, spectral graph methods and sparse subspace self-representation. DSL simultaneously ensures solution interpretability and superior predictive power (up to 16% improvement in challenging instances compared to baselines), with execution times up to an hour for large instances.

Subjects: Political Economy

description: High inflation economies do not always exhibit smooth inflationary processes; sometimes stop-go cycles of inflation are observed. This paper relates these stop-go episodes to a political cycle: Governments can defer inflation until after elections to increase their chances of being reelected. This is modelled as a two-period game of incomplete information where voters try to pick the most competent candidate, and inflation (which is used as a signal of competency) can be lowered by the government in the short run through foreign debt accumulation.

description: We can observe increasing volatility in rapeseed prices caused by the progressing process of globalisation in the turnover and processing of this raw material. It increases the exposure of rapeseed-producing entities and rapeseed-processing enterprises to price risk. The aim of this study is to assess the extreme price risk on the market of rapeseeds and processed rapeseed products in Poland. The study was based on average weekly rapeseed purchase prices and sales prices of refined rapeseed oil, rapeseed meal and rapeseed oilcake from 3 January 2005 and 19 April 2015. Extreme risk was measured with two measures: value at risk and expected shortfall. Extreme value theory was also applied. The research findings point to differences in the level of risk on the market of rapeseeds and processed rapeseed products.

description: This paper examines some popular explanations for the smooth operation of the classical gold standard. We find that the rapid adjustment of economies to underlying disturbances played an important role in stabilizing output and employment under the gold standard system, but no evidence that this success also reflected relatively small underlying disturbances. Finally, the paper also suggests an explanation for the evolution of the international monetary system based on growing nominal inertia over time.
