description: The aim of this paper is to verify, whether business entities associated in the producer groups were more successful than the non-associated ones in the period 2009 – 2012. The results have shown that there are differences between average values of economic indicators of producer groups’ members and those of non-members. We can conclude that there were statistically significant differences between the average revenue per hectare, revenue without subsidies and the average costs per hectare of the agricultural cooperatives associated in the producer groups and those of non-members of sales organisations. The average values of the most economic indicators of the agricultural cooperatives – member of the producer groups, were significantly better than those achieved by the non-associated cooperatives.

description: The heating of trapped ions due to the interaction with a {\it quantized environment} is studied {\it without performing the Born-Markov approximation}. A generalized master equation local in time is derived and a novel theoretical approach to solve it analytically is proposed. Our master equation is in the Lindblad form with time dependent coefficients, thus allowing the simulation of the dynamics by means of the Monte Carlo Wave Function (MCWF) method.

description: The paper aimed to analyse the process maturity of short food supply chains. Process orientation has been recognized as a basic concept of the chains functioning. Based on developed Model of Process Maturity of Short Food Supply Chains, which was used to analyse 35 short food supply chains, it was found that the shorter the chain is and the less people are involved in it, the higher maturity of processes could be observed that is govern by the institution of trust. The researchers identified also the shortage gap and overgrowth gap in the process maturity, which influence the sustainable extension of the short food supply chains.

description: We study the nature of collective excitations in harmonic chains with masses exhibiting long-range correlated disorder with power spectrum proportional to $1/k^α$, where $k$ is the wave-vector of the modulations on the random masses landscape. Using a transfer matrix method and exact diagonalization, we compute the localization length and participation ratio of eigenmodes within the band of allowed energies. We find extended vibrational modes in the low-energy region for $α> 1$. In order to study the time evolution of an initially localized energy input, we calculate the second moment $M_2(t)$ of the energy spatial distribution. We show that $M_2(t)$, besides being dependent of the specific initial excitation and exhibiting an anomalous diffusion for weakly correlated disorder, assumes a ballistic spread in the regime $α>1$ due to the presence of extended vibrational modes.

description: The three-parameter (K, b, and n) Song isotherm model was slightly modified to make it possible to obtain analytical integration of the spreading pressure integral. The modified Song model (MSM) allows more efficient and accurate calculation of the ideal adsorbed solution theory (IAST). The MSM also satisfies the Henry’s law and the Freundlich model at low and high concentrations, respectively, and reverts to the Langmuir and the linear models when n equals zero and one, respectively. Approximate values of each parameter could be estimated from a plot of log (q/c) versus log c; the partition coefficient in the Henry’s law region (K) and the Freundlich index (n) can be estimated from the ordinate value of the low-concentration asymptote and the slope of the high-concentration asymptote, respectively, and the parameter (b) can be estimated from the solution-phase concentration of the intersection point of the two asymptotes. The MSM was fitted to the single-solute sorption of 2-chloro-, 3-cyano-, and 4-nitrophenol onto montmorillonites modified with either HDTMA cation or TMA/HDTMA dual cations. The ideal adsorbed solution theory (IAST) combined with either dual-mode model, Khan model or MSM as a single-solute isotherm model was used to predict three bisolute and one trisolute sorption to organoclays. The Sheindorf-Rebhun-Sheintuch (SRS) and Murali-Aylmore (M-A) were also used to predict bisolute sorption to organoclays. The IAST predictions were generally in good agreement with the multisolute sorption data. The advantages of MSM over other three-parameter models were fully discussed.

description: Stable isotopes of water (δ2H, δ18O) and δ13CTIC were used as a tool to trace the recharge processes, natural carbon (organic and inorganic) source and dynamics in the aquifers of the central Gangetic basin, India. Stable isotope (δ2H, δ18O) record of groundwater (n = 105) revealed that the groundwater of Piedmont was recharged by meteoric origin before evaporation, while aquifers of the older and younger alluvium were recharged by water that had undergone evaporation loss. River Ganges and its tributaries passing through this area have very little contribution in recharging while ponds play no role in the recharging of adjacent aquifers. The connectivity of shallow aquifers of aquitard formation (comprised of clay/sandy clay with thin patches of fine grey sand), i.e. 25–60 m below ground level (bgl) with the main upper aquifer (at a depth of >120 m bgl) was found to be higher in older and younger alluvium. Negative values of δ13CTIC (median −9.6 ‰; range −13.2 to −5.4 ‰) and high TIC (median 35 mM; range 31–46 mM) coupled with low TOC (median 1.35 mg/L; range 0.99–1.77 mg/L) indicated acceleration in microbial activity in the younger alluvium, especially in the active floodplain of river Ganges and its proximity.

description: We define a non-commutative product for arbitrary gauge and B-field backgrounds in terms of correlation functions of open strings. While off-shell correlations are, of course, not conformally invariant, it turns out that, at least to first derivative order, our product has the trace property and is associative up to surface terms if the background fields are put on-shell. No on-shell conditions for the inserted functions are needed, but it is essential to include the full contribution of the Born-Infeld measure. We work with a derivative expansion and avoid any topological limit, which would effectively constrain $H$.

description: In dieser Arbeit sollen die Aufgaben, Praxisfelder sowie die Arbeitsprinzipien der Soziokulturellen Animation und der Kunst- und Kulturvermittlung in musealen Institutionen beschrieben und miteinander verglichen werden. Hierbei sollen auch Unterschiede und Überschneidungen in der Zielgebung sowie im Begriffsverständnis der beiden Professionen definiert und einander gegenübergestellt werden. Die Kunst- und Kulturvermittlung wird aktuell laufend weiterentwickelt und erforscht. Die Vermittlungsarbeit in musealen Institutionen soll einerseits verändert werden und auf einer partizipativeren Ebene stattfinden, andererseits sollen neue Zielgruppen einbezogen werden. Der Einbezug neuer Zielgruppen erfordert dabei neue Konzepte der Vermittlung. In Folge dieser Neukonzeptionierungen findet eine Annäherung an soziokulturelle Arbeitsweisen statt. Dadurch stellt sich die Frage, in welchen Bereichen zwischen den beiden Professionen Synergien denkbar sind und wo sie sich gegenseitig ergänzen können. Die Arbeit ist dabei an Professionelle aus der Soziokulturellen Animation, wie auch aus der Kunstund Kulturvermittlung gerichtet. Sie hat das Ziel aufzuzeigen, welches Potential in einer interdisziplinären Zusammenarbeit liegen könnte. Anhand des Vergleichs der beiden Professionen, sollen mögliche Handlungsansätze hergeleitet und mögliche Forschungsfragen erarbeitet werden.

description: We consider a Schrödinger operator with complex-valued potentials on the line. The operator has essential spectrum on the half-line plus eigenvalues (counted with algebraic multiplicity) in the complex plane without the positive half-line. We determine series of trace formulas. Here we have the new term: a singular measure, which is absent for real potentials. Moreover, we estimate of sum of Im part of eigenvalues plus singular measure in terms of the norm of potentials. The proof is based on classical results about the Hardy spaces.

description: The distribution of arrival directions of ultra-high energy cosmic rays may yield clues to their mysterious origin. We introduce a method of {\it invariant statistics} to analyze cosmic ray data which eliminates coordinate-dependent artifacts. When combined with maximum likelihood analysis, the method is capable of quantifying deviations of the distribution from isotropy with high reliability. We test our method against published AGASA events with energies above $4 \times 10^{19}$ eV. Angular cuts from observational limitations are taken into account. A model based on the Fisher distribution reveals the rotation of the Earth with the axis $\hat n$ along the direction ($5^h 53.36^m, 85.78^{\circ}$) in $(RA,DEC)$ coordinates, which is within $5^{\circ}$ of the equatorial north pole. Global anisotropy of the data, if any, hinges on finer understanding of detector acceptance than what is available from the published literature.

description: In dieser Bachelor-Arbeit mit dem Titel „Förderplanung in Theorie und Praxis“ wird der Frage nachgegangen, inwiefern das Modell der Förderplanung in der sozialpädagogischen, stationären Kinder- und Jugendhilfe als hilfreich und wertvoll erachtet wird. Dabei wird die Förderplanung als Teil des methodischen Handelns in der Sozialpädagogik verstanden. Im Rahmen dieser Arbeit wird anhand von Literatur aus den Sozialwissenschaften das Verständnis ebendieser Förderplanung beleuchtet. Ausserdem wurde eine qualitative Forschung geplant, durchgeführt und ausgewertet. Die Autoren B. Graber und S. Caputo zeigen auf, dass die sozialpädagogische Praxis der stationären Kinder- und Jugendhilfe die Förderplanung auf verschiedenen Ebenen als bedeutend und hilfreich ansieht. Insbesondere erachtet die Praxis die Förderplanung als zentrales Hilfsmittel, um professionelle Arbeit im Rahmen der Sozialpädagogik zu gewährleisten. Aus Sicht der Autoren zeigt die Forschung, dass sich die Förderplanung als Modell in der Praxis etabliert hat und als Teil des Handelns angesehen wird. Die Institutionen sind bestrebt, die eigenen Förderplanungsprozesse so weiterzuentwickeln, dass eine optimale Förderung ermöglicht wird. Das grösste Potential wird in der Umsetzung im Alltag gesehen. Bezüglich dieser Förderplanung stellen sich den Fachkräften im Alltag diverse Herausforderungen. Unterschiedliche Einflussfaktoren wirken auf die Förderplanung ein und es gilt, sich dieser bewusst zu sein sowie die eigenen Förderplanungsprozesse kritisch zu hinterfragen. Die vorliegende Arbeit liefert neue Erkenntnisse – sowohl für die Praxis als auch für die Theorie –, um den Prozess der Förderplanung weiter optimieren zu können.

description: We consider here the question if it is possible to recover cosmic censorship when a transition is made to higher dimensional spacetimes, by studying the spherically symmetric dust collapse in an arbitrary higher spacetime dimension. It is pointed out that if only black holes are to result as end state of a continual gravitational collapse, several conditions must be imposed on the collapsing configuration, some of which may appear to be restrictive, and we need to study carefully if these can be suitably motivated physically in a realistic collapse scenario. It would appear that in a generic higher dimensional dust collapse, both black holes and naked singularities would develop as end states as indicated by the results here. The mathematical approach developed here generalizes and unifies the earlier available results on higher dimensional dust collapse as we point out. Further, the dependence of black hole or naked singularity end states as collapse outcomes, on the nature of the initial data from which the collapse develops, is brought out explicitly and in a transparent manner as we show here. Our method also allows us to consider here in some detail the genericity and stability aspects related to the occurrence of naked singularities in gravitational collapse.

description: We present a simple permanent magnet set-up that can be used to measure the Faraday effect in gases, liquids and solids. By fitting the transmission curve as a function of polarizer angle (Malus' law) we average over fluctuations in the laser intensity and can extract phase shifts as small as $\pm$ 50 $μ$rads. We have focused on measuring the Faraday effect in olive oil and find a Verdet coefficient of $V$ = 192 $\pm$ 1 deg T$^{-1}$ m$^{-1}$ at approximately 20 $^{\circ}$C for a wavelength of 659.2 nm. We show that the Verdet coefficient can be fit with a Drude-like dispersion law $A/(λ^2 - λ_0^2)$ with coefficients $A$ = 7.9 $\pm$ 0.2 $\times$ 10$^{7}$ deg T$^{-1}$ m$^{-1}$ nm$^2$ and $λ_0$ = 142 $\pm$ 13 nm.

description: We present string duals of four dimensional N=2 pure SU(N) SYM theory. The theory is obtained as the low energy limit of D5-branes wrapped on non-trivial two-cycles. Using seven dimensional gauged supergravity and uplifting the result to ten dimensions, we obtain solutions corresponding to various points of the N=2 moduli space. The more symmetric solution may correspond to a point with rotationally invariant classical vevs. By turning on seven dimensional scalar fields, we find a solution corresponding to a linear distribution of vevs. Both solutions are conveniently studied with a D5-probe, which also confirms many of the standard expectations for N=2 solutions.

description: Total reaction cross sections are predicted for nucleons scattering from various nuclei. Projectile energies to 300 MeV are considered. So also are mass variations of those cross sections at selected energies. All predictions have been obtained from coordinate space optical potentials formed by full folding effective two-nucleon (NN) interactions with one body density matrix elements (OBDME) of the nuclear ground states. Good comparisons with data result when effective NN interactions defined by medium modification of free NN t matrices are used. Coupled with analyses of differential cross sections, these results are sensitive to details of the model ground states used to describe nuclei.

description: In superconducting circuit architectures for quantum computing, microwave resonators are often used both to isolate qubits from the electromagnetic environment and to facilitate qubit state readout. We analyze the full counting statistics of photons emitted from such driven readout resonators both in and beyond the dispersive approximation. We calculate the overlap between emitted-photon distributions for the two qubit states and explore strategies for its minimization with the purpose of increasing fidelity of intensity-sensitive readout techniques. In the dispersive approximation and at negligible qubit relaxation, both distributions are Poissonian, and the overlap between them can be easily made arbitrarily small. Nondispersive terms of the Hamiltonian generate squeezing and the Purcell decay with the latter effect giving the dominant contribution to the overlap between two distributions.

description: The objective of this paper was to examine the cost efficiency of corn and soybean production for typical farms involved in the cash crop agri benchmark network. Using a data envelopment analysis (DEA) approach, efficiency indices were computed for 35 corn farms, representing 15 countries including Argentina, Bulgaria, Brazil, China, Czech Republic, France, Hungary, Italy, Poland, Russia, Ukraine, United States, Uruguay, Vietnam, and South Africa. Average technical efficiency was 0.497, average allocative efficiency was 0.487, and average cost efficiency was 0.310. Efficiency indices were also found for 18 soybean farms, representing 9 countries, including Argentina, Brazil, Canada, China, Italy, Ukraine, United States, Uruguay, and South Africa. Average technical efficiency was 0.533, average allocative efficiency was 0.553, and average cost efficiency was 0.340. Correlation analysis shows that seed input cost shares were the most correlated with cost efficiency for soybeans, while fixed capital cost shares were the most correlated with cost efficiency for corn production. OLS regression indicated that land, labor and other direct services were under-utilized for corn production, and that seed was over-utilized for soybean production.

description: COVID-19 has created many constraint-related challenges for humans in general and organisations in particular. Specifically, businesses that require physical contact, such as mobility providers, have been severely impacted by the crisis. This paper reveals how mobility platforms and their ecosystem of actors have adapted faster than their non-platform competitors to become resilient. Whereas current research on resilience explicitly deals with the concept of organisational resilience, community resilience, or IT resilience, socio-technical characteristics of digital platforms have not been investigated. We build on a case survey approach, including heterogeneous qualitative evidence of 266 actions of 171 analysed mobility platforms. The results show five archetypes of how mobility platforms leverage their platform-based nature and the ecosystem to build resilience. Based on this, we develop the concept of platform ecosystem resilience as leveraging socio-technical factors of digital platforms and ecosystems frugally to design, deploy and use situation-specific responses to prepare for, endure and adapt by capturing new opportunities and engaging in transformative activities to cope with exogenous shocks and become resilient for future disruptions. Our results emphasise the importance of platform ecosystems for practitioners and policy planners to develop the “new normal” rather than resuming existing practices.

description: Kunst und innerhalb dieser die Architektur ist Ausdruck der zeitlichen Gegebenheiten. Diese waren 1945 nach der mentalen und physischen Hinterlassenschaft des Naziregimes desaströs, Stuttgart - die Heimatstadt des Architekten Rolf Gutbrod (1910 - 1999) - war völlig untergegangen. Wie sollte der Wiederaufbau geschehen? Als Anknüpfung an die erste Stuttgarter Bauschule vor 1933, als Anpassung an den „internationalen Stil“ als Re-Import des Bauhausstils? Ein kleines Gebäude - die Milchbar auf dem Stuttgarter Höhenpark Killesberg 1950, die einer Bauzeitung als sonderbar bezeichnet wird, um sie in der Folge als Befreiung zu loben - steht am Anfang der individualisierten Baukunst des Architekten Rolf Gutbrod. Yehudi Menuhin - wer könnte besser ein Werk einer verwandten Kunstgattung bewerten als er? - findet für das Konzerthaus Liederhalle 1956 die folgenden Worte: Nachdem ich nun schon zum zweiten Male in Ihrer neuen Liederhalle konzertiert habe, schreibe ich Ihnen, um Ihnen zu diesem Gebäude Glück zu wünschen. Der Raum ist akustisch hervorragend. Dabei hat seine geniale Asymmetrie für den Künstler etwas geradezu Befreiendes. In ihm scheint die mechanistische Perfektion, die unsere Kultur so bedroht, überwunden zu sein. Die freie Bewegtheit des Raumes steht in einem direkten Zusammenhang mit der freien Bewegtheit der Kunst der Musik. In einem solchen Raum ist es leicht, neue und alte Musik schöpferisch nachzuschaffen. Dass gerade in Deutschland, dem der Ruf der Reglementierung auch im Geistigen noch immer anhaftet, ein solches Gebäude an so wichtiger Stelle entstand, freut mich tief. Christoph Hackelsberger schrieb Mitte der 1980er Jahre über dieses Gebäude: Die äußere Erscheinung befremdete in ihrer Neuartigkeit nicht nur die Traditionalisten, sondern auch die Anhänger der klassischen Moderne. So entstand mitten in der Orientierungsphase der deutschen Architektur ein autochthones, organisches Baukunstwerk. In dieser Studie wird am Beispiel exemplarischer Bauwerke das Autochthone des Werks des Architekten, das so erfrischend vor dem Hintergrund der gegenwärtigen Kubenarchitektur wirkt, dargestellt.

description: Phasor Measurement Unit (PMU) technology is increasingly used for real-time monitoring applications, especially line outage detection and identification (D&I) in the power system. Current outage D&I schemes either assume a full PMU deployment or a partial deployment with fixed PMU placement. However, the placement of the PMUs has a fundamental impact on the effectiveness of the D&I scheme. Building on a dynamic relationship between the substation voltage phase angle and active power, we formulated the optimal PMU placement problem for outage D&I as an optimization problem readily solvable by any heuristic algorithm. We tested the formulation using a genetic algorithm and simulated outages of IEEE 39 bus system. The optimal placement found produces a better D&I result of single-line outages than a randomly scattered, tree-like, and degree-based placements.

description: The United States accounts for one of the highest per-capita caloric sweetener consumption in the world. The American Heart Association recommends a maximum of around 6 to 9 teaspoons of per-capita sweetener consumption per day (equivalent to 23.8 pounds to 35.71 pounds per-capita, per year). The current US per-capita sweetener consumption is approximately 19 teaspoons/day. This high sweetener consumption is often linked to major health ailments such as obesity, Type 2 diabetes, and cardiovascular diseases. This study uses a supply and demand framework to evaluate the amount of excise tax on major sweeteners (sugar and high fructose corn syrup) sufficient to reduce excess sweetener consumption to the recommended level. Results suggest a maximum consumer tax of 12 cents per pound on both sugar and HFCS sufficient to reduce consumption to the recommended level. Also, a maximum producer tax of 25 cents per pound on sugar and 95 cents per pound on HFCS is suggested to reduce consumption to the recommended level.

description: When policies are changed it is not uncommon for losers to be compensated. Economic theory and quantitative analysis are useful in determining the efficiency gains/losses associated with a policy change, but are little help in deciding what the approach to compensation should be. The amount of compensation varies, depending on, in part, the political clout of the parties being negatively affected by a policy change—compensation is what politicians and the sector demanding compensation can agree on. We formulate four approaches to producer compensation within the context of the Ontario Tobacco Transition Program where producers would have suffered losses in the absence of compensation. The approaches range from providing zero-compensation to providing compensation based on the entire value of the tobacco quota. The Canadian government chose to compensate producers for the termination of the tobacco quota program based on an approach that far exceeded other possible compensation approaches. Importantly, efficiency is not affected by the compensation approach.

description: We consider the one-dimensional dynamics of nonlinear non-dispersive waves. The problem can be mapped onto a linear one by means of the hodograph transform. We propose an approximate scheme for solving the corresponding Euler-Poisson equation which is valid for any kind of nonlinearity. The approach is exact for monoatomic classical gas and agrees very well with exact results and numerical simulations for other systems. We also provide a simple and accurate determination of the wave breaking time for typical initial conditions.

description: A generation procedure, based on the 5-dimensional covariance of the Kaluza-Klein theory, is developed. The procedure allows one to obtain exact solutions of the 4-dimensional Einstein equations with electromagnetic and scalar fields from vacuum 5-dimensional solutions using special 5-dimensional coordinate transformations. Relations between the physical properties of the resulting solutions and invariant geometrical properties of the generating Killing vectors are found out.

description: Cooperatives operate under a business model that creates unique challenges in financial management, governance, strategy, and communication. There have been a number of efforts to identify challenges, critical issues and success factors for agricultural cooperatives. One of the issues agricultural cooperatives are facing is the relationship between managers and the board of directors. Directors in a cooperative occupy a crucial position between members and hired management. Acting as a group, directors set the objectives for the cooperative and decide what the cooperative will do while the general manager decides how it can best be done, subject to board review. Success of a cooperative mainly depends on good board/ manager relationships. This study was focused on evaluation of impact of the relationship between the board of directors and managers on performance of agricultural cooperatives. That data originated from a mail survey and personal interviews among managers and chairmen of agricultural cooperatives in Texas. The results showed that size of the cooperative had negative impact on performance while more frequent engagement of the managers in strategic planning, higher level of managers’ job satisfaction, and organizational commitment positively affect the profitability of a cooperative.

description: The poor air quality accompanying rapid economic growth in China attracted public attention worldwide when severe haze episodes caused by PM2.5 broke out in several major Chinese cities in 2011 and again in 2013 and early 2014. Previous studies have focused on the source of haze and its health impacts. Our study is the first to provide an analysis of pollution avoidance behavior by the Chinese in response to the recent haze episodes. We track the spatial-temporal variation of daily sales of anti-PM2.5 facemasks. In a standard utility maximization framework, the demand for anti-PM2.5 facemasks is a function of their price, the price of substitutes and other demand shifters affecting risk perceptions (visibility, level of PM2.5, haze alerts). We investigate whether an averting behavior exists, and how the purchases of masks depend on PM2.5 levels, and other factors directly observable: visibility and alert information. By providing insights on how citizens respond to air pollution, our research can help inform government agencies on how to better formulate policies to reduce exposure to air pollution and to more effectively communicate pollution alerts to those affected.

Automated Transverse Momentum Resummation for Electroweak Boson Production
Creators: name: Hager, Monika
Publisher: name: Universität Bern
Year: 2019
Subjects: 530 Physics

description: The production of electroweak bosons, followed by leptonic decays, is among the most basic hard-scattering processes studied at hadron colliders. Such processes provide backgrounds to new physics searches, enable the study of possible anomalous gauge couplings and provide spectra for determining the W boson mass and the angle θW. At small transverse momentum qT , the electroweak boson production processes involve disparate scales, namely the small qT and the large mass M of the bosonic states. Fixed-order perturbative results suffer from large logarithms of the ratio of these scales and hence become unreliable. The appropriate treatment of these logarithms is their resummation. This thesis presents a framework for transverse momentum resummation for quark-induced boson production processes with arbitrary electroweak final states. The resummation is performed in an automated way and is based on reweighting events generated using a tree-level event generator. The kinematics of the electroweak final states are accessible, and this allows for the analysis of general observables in the small transverse momentum region. Making use of the event generator MadGraph5_aMC@NLO, the resummation is implemented at next-to-next-to-leading logarithmic accuracy and matched to next-to-leading fixed-order results. Results for Z and W boson production with leptonic decay as well as for WZ production are presented. The predictions are validated using an existing resummation code and compared to experimental measurements.

description: The capabilities of a neutrino factory in the determination of polarized parton distributions from charged-current deep-inelastic scattering experiments is discussed. We present a study of the accuracy in the determination of polarized parton distributions that would be possible with such a facility. We show that these measurements have the potential to distinguish between different theoretical scenarios for the proton spin structure.

description: This paper estimates the Total Factor Productivity (TFP) index for the U.S. agricultural sector from the period 1970 to 2004 and decomposes the resulting TFP estimation in the Trans-logarithmic production function for U.S. agriculture for the same period to determine the residual measure that explains variation in output aside from land, labor and capital inputs. The objective is to identify the major sources of agricultural productivity in the U.S. from the period mentioned and furthermore estimate the residual in the production function that the Neoclassical production function does not explicitly explain.The results indicate a collective contribution of intermediate inputs such as pesticides use and energy inputs and infrastructural development spending such as overall federal disbursement on highway on TFP and consequently on agricultural output growth for the time period under consideration.
