description: The article shows the changes in labor productivity that have occurred in the past decade, such as in 2000-2010, in the Polish food industry and its various sectors, measured value of sold production per employee. Improving the labour productivity was a common phenomenon and affect all sectors of the food industry, although the rate of change was different. The growth rate of labor productivity in the Polish food industry had one of the highest among the countries of the Community, in particular with regard to the most developed countries, ie the EU-15. This means that gradually reduce the gap separating us in this area, and thus become more competitive. It is very important that we are losing comparative advantages such as lower prices of agricultural raw materials and media, for example electricity, water. / Synopsis. W artykule pokazano zmiany wydajności pracy, jakie nastąpiły w minionej dekadzie, tj. w latach 2000-2010, w polskim przemyśle spożywczym i jego poszczególnych branżach, mierzonej wartością produkcji sprzedanej na zatrudnionego. Poprawa wydajności pracy była zjawiskiem powszechnym i dotyczyła wszystkich branż przemysłu spożywczego, aczkolwiek tempo tych zmian było różne. Tempo wzrostu wydajności pracy w polskim przemyśle spożywczym należało do jednego z najwyższych wśród krajów Wspólnoty, zwłaszcza w odniesieniu do krajów najbardziej rozwiniętych, tj. UE-15. Oznacza to, że sukcesywnie zmniejszamy dzielący nas dystans w tym obszarze, a tym samym stajemy się bardziej konkurencyjni. Jest to o tyle ważne, że tracimy inne przewagi komparatywne w postaci m.in. niższych cen surowców rolnych czy mediów, np. prądu, wody.

description: We theoretically discuss the non-Hermitian superfluid phase transition in one-dimensional two-component Fermi gases near the $p$-wave Feshbach resonance accompanied by the two-body loss associated with the dipolar relaxation. For the first time we point out that this system gives us an opportunity to explore the interplay among various non-trivial properties such as universal thermodynamics at divergent $p$-wave scattering length, topological phase transition at vanishing chemical potential, and non-Hermitian Bardeen-Cooper-Schrieffer(BCS) to Bose-Einstein condensate (BEC) transition, in a unified manner. In the BCS phase, the loss-induced superfluid-normal transition occurs when the exceptional point appears in the effective non-Hermitian Hamiltonian. In the BEC phase, the diffusive gapless mode can be regarded as a precursor of the instability of the superfluid state. Moreover, we show that the superfluid state is fragile against the two-body loss near the topological phase transition point.

description: We present a 2.5 sigma detection of the Integrated Sachs-Wolfe (ISW) effect and discuss the constraints it places on cosmological parameters. We cross-correlate microwave temperature maps from the WMAP satellite with a 4000 deg^2 luminous red galaxy (LRG) overdensity map measured by the Sloan Digital Sky Survey. Accurate photometric redshifts allow us to perform a reliable auto-correlation analysis of the LRGs, eliminating the uncertainty in the galaxy bias, and combined with cross correlation signal, constrains cosmological parameters -- in particular, the matter density. We find a 2.5 sigma signal in the Ka, Q, V, and W WMAP bands, after combining the information from multipoles 2 <= l < 400. This is consistent with the expected amplitude of the ISW effect, but requires a lower matter density than is usually assumed: the amplitude, parametrized by the galaxy bias assuming Ω_M=0.3, Ω_Λ=0.7 and σ_8=0.9, is b_g = 4.05 \pm 1.54 for V band, with similar results for the other bands. This should be compared to b_g = 1.82 \pm 0.02 from the auto-correlation analysis. These data provide only a weak confirmation (2.5 sigma) of dark energy, but provide a significant upper limit: Ω_Λ=0.80_{-0.06}^{+0.03} (1 sigma)_{-0.19}^{+0.05} (2 sigma), assuming a cosmology with Ω_M+Ω_Λ=1, Ω_b = 0.05, and σ_8=0.9, and w=-1. The weak cross-correlation signal rules out low matter density/high dark energy density universes and, in combination with other data, strongly constrains models with w

description: The long-term viability of farm businesses has been a stated goal for agricultural policy in most developed and developing economies. Recent investigations have found the level and type of diversification to be a significant factor in determining viability. This paper presents an index of short term and long term viability over the period 2000-2012 across Scotland and Sweden. Transition probabilities are presented using a balanced Markov chain approach. We find stability in both viable and non-viable farms over time, irrespective of policy and market change. A multinomial logistic regression finds the influence agaricultural diversification on determining higher levels of viability at the farm level.

description: We present an updated timing solution for the young, energetic pulsar PSR B1509-58 based on 21.3 years of radio timing data and 7.6 years of X-ray timing data. No glitches have occurred in this time span, in contrast to other well-studied young pulsars, which show frequent glitches. We report a measurement of the third frequency derivative of (-1.28+/-0.21)x10^(-31) s^(-4). This value is 1.65 standard deviations from, i.e. consistent with, that predicted by the simple constant magnetic dipole model of pulsar spin-down. We measured the braking index to be n=2.839+/-0.003 and show that it varies by 1.5% over 21.3 yr due to contamination from timing noise. Results of a low-resolution power spectral analysis of the significant noise apparent in the data yield a spectral index of alpha=-4.6+/-1.0 for the red noise component.

description: Pathogen outbreaks (i.e., outbreaks of bacteria and viruses) in hospitals can cause high mortality rates and increase costs for hospitals significantly. An outbreak is generally noticed when the number of infected patients rises above an endemic level or the usual prevalence of a pathogen in a defined population. Reconstructing transmission pathways back to the source of an outbreak -- the patient zero or index patient -- requires the analysis of microbiological data and patient contacts. This is often manually completed by infection control experts. We present a novel visual analytics approach to support the analysis of transmission pathways, patient contacts, the progression of the outbreak, and patient timelines during hospitalization. Infection control experts applied our solution to a real outbreak of Klebsiella pneumoniae in a large German hospital. Using our system, our experts were able to scale the analysis of transmission pathways to longer time intervals (i.e., several years of data instead of days) and across a larger number of wards. Also, the system is able to reduce the analysis time from days to hours. In our final study, feedback from twenty-five experts from seven German hospitals provides evidence that our solution brings significant benefits for analyzing outbreaks. It is also applicable to COVID-19 hospital-associated transmissions.

description: This paper makes an analysis of changes in both level and structure of rural production in Poland and in other EU countries. An author compared the year 2011 and 2004. An analysis showed that changes in Polish agriculture have the same direction like in EU. In surveyed period the growth of agricultural production is observed to be distinctly greater. The changes in production structure concern the diminishing tendency of both grain, sugar beets, potatoes and slaughter production but increasing tendency of rape and milk production. Despite of the above mentioned changes the share of Poland in Union rural production of mentioned products has not changed considerably. / Synopsis. W opracowaniu dokonano analizy zmian, jakie zaszły w poziomie oraz strukturze produkcji rolniczej w Polsce oraz w pozostałych krajach UE. Przedmiotem porównania był w rok 2011 oraz 2004. Wyniki badań pokazały, że zmiany dokonujące się w polskim rolnictwie mają podobny kierunek jak w UE. W badanym okresie obserwuje się wyraźny wzrost wartości produkcji rolniczej, w Polsce wyniósł on blisko 65%. Zmiany w strukturze produkcji wyrażają się zmniejszeniem produkcji zbóż, buraków cukrowych, ziemniaków i żywca wieprzowego oraz wzrostem produkcji rzepaku i mleka. Pomimo tych zmian, udział Polski w produkcji unijnej wymienionych produktów nie uległ istotnym zmianom.

description: This study mostly rejects the flexible-price monetary model of exchange rate determination as a valid tool for establishing the drivers behind exchange rate movements in the case of the US Dollar, the Euro, the British Pound the Swiss Franc with respect to the Brazilian Real, in the period 1999:Q1 and 2016:Q4. The procedure applied in the analysis is Johansen maximum likelihood estimation to establish the cointegrating relations and to calculate the vector error correction model. Even though substantial evidence for cointegration between the variables is found, the restrictions implied by the model on the proportionality between variables are soundly rejected.

description: Multispeckle x-ray photon correlation spectroscopy was employed to characterize the slow dynamics of a colloidal suspension formed by highly-charged, nanometer-sized disks. At scattering wave vectors $q$ corresponding to interparticle length scales, the dynamic structure factor follows a form $f(q,t) \sim \exp[-(t/τ)^β$], where $β\approx$ 1.5. The characteristic relaxation time $τ$ increases with the sample age $t_a$ approximately as $τ\sim t_a^{1.8}$ and decreases with $q$ approximately as $τ\sim q^{-1}$. Such a compressed exponential decay with relaxation time that varies inversely with $q$ is consistent with recent models that describe the dynamics in disordered elastic media in terms of strain from random, local structural rearrangements. The amplitude of the measured decay in $f(q,t)$ varies with $q$ in a manner that implies caged particle motion at short times. The decrease in the range of this motion and an increase in suspension conductivity with increasing $t_a$ indicate a growth in the interparticle repulsion as the mechanism for internal stress development implied by the models.

Finite differencing second order systems describing black hole spacetimes

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Keeping Einstein's equations in second order form can be appealing for computational efficiency, because of the reduced number of variables and constraints. Stability issues emerge, however, which are not present in first order formulations. We show that a standard discretization of the second order ``shifted'' wave equation leads to an unstable semi-discrete scheme if the shift parameter is too large. This implies that discretizations obtained using integrators such as Runge-Kutta, Crank-Nicholson, leap-frog are unstable for any fixed value of the Courant factor. We argue that this situation arises in numerical relativity, particularly in simulations of spacetimes containing black holes, and discuss several ways of circumventing this problem. We find that the first order reduction in time based on ``ADM'' type variables is very effective.

description: Transport of rodlike particles in confinement environments of macromolecular networks plays crucial roles in many important biological processes and technological applications. The relevant understanding has been limited to thin rods with diameter much smaller than network mesh size, although the opposite case, of which the dynamical behaviors and underlying physical mechanisms remain unclear, is ubiquitous. Here, we solve this issue by combining experiments, simulations and theory. We find a nonmonotonic dependence of translational diffusion on rod length, characterized by length commensuration-governed unconventionally fast dynamics which is in striking contrast to the monotonic dependence for thin rods. Our results clarify that such a fast diffusion of thick rods with length of integral multiple of mesh size follows sliding dynamics and demonstrate it to be "anomalous yet Brownian". Moreover, good agreement between theoretical analysis and simulations corroborates that the sliding dynamics is an intermediate regime between hopping and Brownian dynamics, and provides a mechanistic interpretation based on the rod-length dependent entropic free energy barrier. The findings yield a principle, that is, length commensuration, for optimal design of rodlike particles with highly efficient transport in confined environments of macromolecular networks, and might enrich the physics of the diffusion dynamics in heterogeneous media.

description: A simple and efficient variational method is introduced to accelerate the convergence of the eigenenergy computations for a Hamiltonian H with singular potentials. Closed-form analytic expressions in N dimensions are obtained for the matrix elements of H with respect to the eigenfunctions of a soluble singular problem with two free parameters A and B. The matrix eigenvalues are then optimized with respect to A and B for a given N. Applications, convergence rates, and comparisons with earlier work are discussed in detail.

description: Pig market is the leading meat market in the world in terms of supply and demand and it has also a high share in foreign trade. In the coming years, the importance of the industry to the world economy will grow, due to the development of production in developing countries and increased demand for pork meat as a result of population growth, increasing affluence of the countries in the world and changing consumption patterns. On the other hand, you can see some of the factors limiting the development of the sector, such as the rising cost of farming, the requirements of the environment or climate change. The aim of the paper is to present the current situation in the production and foreign trade of pigs in the world and to indicate the possible direction of change by the year 2020, against the background of global conditions. The study is a review of literature and data, with elements of deductive reasoning. / Synopsis. Rynek mięsa wieprzowego jest wiodącym rynkiem mięsnym na świecie pod względem wielkości podaży i popytu, wysoki jest też udział tego surowca w handlu zagranicznym. W najbliższych latach znaczenie branży dla gospodarki światowej będzie wzrastać, z uwagi na rozwój produkcji w krajach rozwijających się i wzrost zapotrzebowania na surowiec jako rezultat przyrostu liczby ludności, zwiększającej się zamożności części krajów na świecie i zmiany struktury konsumpcji. Z drugiej strony zaobserwować można pewne czynniki ograniczające rozwój ryku, takie jak rosnące koszty produkcji żywca wieprzowego, wymogi w zakresie środowiska naturalnego lub zmiany klimatyczne. Celem pracy jest zaprezentowanie bieżącej sytuacji w produkcji i handlu zagranicznym na rynku mięsa wieprzowego na świecie oraz wskazanie możliwego kierunku zmian do roku 2020, na tle uwarunkowań globalnych.

description: The study presents an analysis of factors influencing the selection, strengthening and consolidation of good economic relations in the European food chains. Four basic types of economic relations have been established, taking the form of transactions and type of management as the main criteria. These include: spot markets, repeated market transactions with the same supplier-recipient, formal written contracts and financial participation. Empirical material has been gathered in the form of questionnaires in 13 European food chains located in 6 EU Member States: Germany, Ireland, Great Britain, Finland, Spain and Poland. Among the examined States, formal relations are most common in Finland and Spain; least common: between farmers-processing plants in Ireland. Among the examined food chains most formalised relations are in the beer chain (mainly between processing plants and retail sellers) and pork chain (farmer-processing plant). Chains involving bakery and beef show significantly lower level of formalised relations. The results of the study indicate that the main factors determining the quality of relations between the participants of examined food chains are: good communication, personal connections and even distribution of competitive power between business partners of the chain. Also the dependence of quality and sustainability of economic relations on the type of product, country and location of the partners in the chain (level) has been identified. No significant dependence of the nature of economic relations against the type of business connection and level of their formalisation has been identified.

description: An identity denotes the role an individual or a group plays in highly differentiated contemporary societies. In this paper, our goal is to classify Twitter users based on their role identities. We first collect a coarse-grained public figure dataset automatically, then manually label a more fine-grained identity dataset. We propose a hierarchical self-attention neural network for Twitter user role identity classification. Our experiments demonstrate that the proposed model significantly outperforms multiple baselines. We further propose a transfer learning scheme that improves our model's performance by a large margin. Such transfer learning also greatly reduces the need for a large amount of human labeled data.

description: The purpose of this paper is testing eciency of the Germany and UK stock mar- ket. German DAX and FTSE 100 stock market data show that the stock returns tend to have a leptokurtic probability distribution rather than normal distribution. Moreover, the stock returns rst and second serial correlation tends to increase dur- ing the crisis which implies that when the market is not ecient the predictability of stock return increase, and investors get the opportunities to gain pro ts. Applying a test proposed by Gibbons et al. (1989) on all assets of Germany DAX with 110 months return data over the period August 1999 to April 2017 shows that the null hypothesis of eciency is rejected at the periods of the crisis. Furthermore, there is a weak positive correlation between a twelve-month moving average P-Values of the test and excess returns of long/short equity strategies over the period of January of 2006 to December of 2011. On the other hand, Applying a test proposed by Pesaran and Yamagata (2012) on all assets of FTSE 100 with 60 months return data over the period February 2000 to April 2017 shows that the null hypothesis of eciency rejected at the periods of the crisis. Furthermore, there is a weak positive correlation between a twelve-month moving average P-Values of both tests and excess returns of long/short equity strategies over the period of January of 2001 to December of 2006.

description: Nonlinear control techniques by means of a software sensor that are commonly used in chemical engineering could be also applied to genetic regulation processes. We provide here a realistic formulation of this procedure by introducing an additive white Gaussian noise, which is usually found in experimental data. Besides, we include model errors, meaning that we assume we do not know the nonlinear regulation function of the process. In order to illustrate this procedure, we employ the Goodwin dynamics of the concentrations [B.C. Goodwin, Temporal Oscillations in Cells, (Academic Press, New York, 1963)] in the simple form recently applied to single gene systems and some operon cases [H. De Jong, J. Comp. Biol. 9, 67 (2002)], which involves the dynamics of the mRNA, given protein, and metabolite concentrations. Further, we present results for a three gene case in co-regulated sets of transcription units as they occur in prokaryotes. However, instead of considering their full dynamics, we use only the data of the metabolites and a designed software sensor. We also show, more generally, that it is possible to rebuild the complete set of nonmeasured concentrations despite the uncertainties in the regulation function or, even more, in the case of not knowing the mRNA dynamics. In addition, the rebuilding of concentrations is not affected by the perturbation due to the additive white Gaussian noise and also we managed to filter the noisy output of the biological system

title: Unemployment In Austria: job losing and job finding
Creators: name: Girstmair, Stefan
Publisher: name: TU Wien
Year: 2017
Subjects: subject: Unemployment
subject: Job Finding Probability
subject: Job Losing Probability

description: This thesis uses Austrian administrative data to analyze the evolution of the unemployment rate and the associated job losing and job finding probabilities. Following a recent paper by Hornstein (2012), the rates are split up between shortand long term unemployment to further identify movements in the Austrian labor market. I use a logistic regression model with seasonal dummy variables to estimate the transition probabilities between employment and unemployment. In alignment with Hornstein (2012), the results indicate that the job losing rate increases in recessions while the job finding rate decreases. Moreover, the job total finding probability has a downwards trend over the observed period. A further interesting result, following the literature, is the increase of long-term unemployed as a share of the overall unemployment pool during recessions.
Three-dimensional bond-order instability in infinite-layer nickelates due to nonlocal quantum interference

description: Recently discovered superconducting infinite-layer nickelates $R$NiO$_2$ ($R$=Nd, La, Pr) attracts increasing attention as a similar system to cuprates. Both $R$NiO$_2$ and YBCO cuprates display the three-dimensional (3D) CDW with wave vector ${\bf q}\sim(2π/3,0,q_z)$, while $q_z$ is non-zero and incommensurate in the former system. Here, we reveal that the characteristic CDW in $R$NiO$_2$ can be naturally explained as the quantum interference between paramagnons, by focusing on the following characteristics of $R$NiO$_2$: (i) prominent three-dimensionality in the Fermi surface and (ii) large self-hole-doping ($\sim 14$%). This mechanism predicts the emergence of the $d_{x^2-y^2}$-wave bond order at a secondary 3D nesting vector ${\bf q}^c\sim(2π/3,0,q^c_z)$ $(q^c_z=0.2π\sim 2π/3)$. The obtained strong bond fluctuations lead to the non-Fermi liquid electronic states and superconducting states in nickelates.

title: Contracting under asymmetric information and asymmetric awareness

Subjects: subject: Unawareness
subject: Information
subject: Contract Theory

description: I study a principal-agent contracting problem in which problems of asymmetric information and asymmetric awareness are present. I consider an insurance situation in which two types of agents know only a subset of the possible contingencies leading to damage over some good. The insurer is fully aware. However the insurer does not know which contingencies the insuree is originally aware of. The model is reduced to study the case of two types and three states or contingencies. A type who becomes aware of a contingency updates his awareness by assigning some residual probability to that event. The principal has the choice of which contingencies to cover, along with how to structure the terms of his contract to appeal to the various types. I hypothesize that the distribution of types of agents, updating parameters and levels of suspicion has an eect on the terms of the optimal contract. First a general solution method of the optimization problem of the principal is oered together with general characterizations of solutions. It is shown that certain distributions of types induce the principal to reveal information out of self interest, thereby altering the awareness of the dierent types of insurees and inducing more complete contracts.
Condition and Perspectives for Development of Russian Agriculture

description: Agriculture in Russia is in the process of restructuring and overcoming the production and economic crisis. Measures undertaken in order to make agricultural development more dynamic are only partially successful. The level of agricultural production is still lower than in 1990-1991. Particularly strong difficulties can be observed in attempts to accelerate development of animal production. In conditions of rapid increase of people's income, increase in production achieved in last few years did not bring the reduction of dynamics of increasing food imports nor did it improve the country's food self-sufficiency. As a result Russia becomes a bigger and bigger importer of agricultural and food products, especially of animal origin. Analyses indicate that even full implementation of tasks written down in the programme for the development of agriculture for 2008-2012 and satisfying assumptions concerning the improvement of country's food security, would not lead to Russia's food self-sufficiency even in 2020. At the same time Russia, due to low level of development of animal-origin food production, is a large and growing exporter of cereal, oil plants and oil. Russia's entering into WTO and the financial crisis can hamper development trends in Russian agriculture. Simultaneously, however, these factors can also limit dynamics of the national demand for food. Such conditions may cause further increase of export of vegetable products.
Rape as torture : an analysis of sexual torture in international humanitarian law and the domestic law of Sri Lanka
Creators: name: Merry, Michelle Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: Sexual violence has become an increasingly visible aspect of armed conflict. Over the last decade, feminists have critiqued the lack of attention given to sexual violence in international humanitarian law and have made important contributions to the developing area of international criminal law by bringing a gender perspective to that field. This thesis examines whether characterizing rape as torture is the best way to respond to the injustices suffered by women during armed conflict. Charging rape as torture offers substantive benefits; yet, such a characterization risks leaving the sexual and gender aspects of the crime invisible. First, I examine the development of recognizing rape as torture by reviewing jurisprudence from the ICTY, ICTR, and regional human rights courts. Second, in order to measure the potential benefits of characterizing rape as torture in national legal systems, I examine reports of custodial rape from Sri Lanka and analyze provisions in Sri Lankan law which could be used to deal with such cases. I conclude that characterizing rape as torture offers significant legal advantages; however, in order to properly recognize the experiences of women who have suffered rape during armed conflict both rape and torture should be charged. The central element in the crime of rape is that a physical invasion of a sexual nature occurred under coercion, whereas the central element in torture is that an act of severe pain or suffering took place.
The Nature of the Young Supernova Remnant S8 in the Dwarf Galaxy IC 1613

description: We present sub-arcsecond optical images and low- to moderate-resolution spectra of the compact, X-ray and optically bright supernova remnant known as S8 in the nearby dwarf galaxy IC 1613. Deep H$α$ images of the remnant show a sharply defined crescent shaped nebula, while narrow passband images reveal a coincident and unexpectedly bright continuum nebulosity exhibiting a size and morphology like that seen for the remnant's line emissions. Low-dispersion spectra covering 3600 - 9000 A show numerous low-ionization line emissions such as [O I] and [Fe II], along with higher-ionization emission lines including He II and optical coronal lines [Fe VII], [Fe X], [Fe XI], and [Fe XIV]. This suggests the presence of a wide range of shock velocities from $\sim$ 50 to over 350 km s$^{-1}$, corresponding to preshock densities of $\sim1 - 30$ cm$^{-3}$. Higher resolution spectra indicate an expansion velocity around 180 km s$^{-1}$ with a $\sim45$ km s$^{-1}$ wide central cavity. H$α$ emission spans rest frame velocities of $+120$ to $-240$ km s$^{-1}$ and we estimate a total nebula mass of $119 \pm 34$ M$_{\odot}$. We conclude S8 is a relatively young supernova remnant ($\simeq2700 - 4400$ yr) exhibiting properties remarkably like those seen in the young LMC remnant N49, including age, physical size, shock velocities, filament densities, optical line strengths, X-ray and optical luminosities, and coronal line and continuum emissions.

title: The effect of information on ambiguous portfolio choices
Creators: name: Illyés, Árpád
Publisher: name: TU Wien
Year: 2017
Subjects: subject: Smooth ambiguity aversion
subject: Portfolio choice
subject: Information

description: This paper analyzes an extension of the portfolio choice model under ambiguity of Gollier (2011) which uses the smooth model of ambiguity. It introduces an additional information setting the investor can acquire that can reduce the exposure to ambiguity. Within this framework it is shown that acquiring information about the plausible return distributions increases the ex ante welfare of the investor. The relation of the average ex ante investment and the original investment level under no information is also examined. Throughout various examples it is demonstrated that this relation is not so clear. When the case of constant absolute ambiguity aversion is considered, however it can be established that under certain conditions information increases the average investment, as absolute ambiguity aversion tends to infinity.

description: Based on farm panel data we empirically investigate the determinants of Polish farm households' flexibility from 1994 to 2001. we focus on scale flexibility (adjustment in production volume) and scope flexibility (adjustment in product mix). The findings of our fixed-effects regression provide evidence that smaller farms are more flexible, both with regard to scale and scope of production. Farms with a higher share of variable costs tended to be more flexible, while producers who specialized in capital- intensive technologies turned out to be less flexible. Some results differ significantly from the prevailing expectations, in particular we found that farms where a generational succession took place displayed less flexibility over time. Moreover, access to off-farm income and finances have opposite effects on scale and scope flexibility. An explanation for these outcomes may be the varying term structure of liquidity sources. There are relevant differences in the strategies Polish farmers used to adjust to changing environmental conditions during transition, which should be taken into account in the design of supporting policies.
