description: This paper analyze the problems of water resource allocation and crop choice in a river basin using spatial analytical tools. Spatial variability of water availability is modelled by the product sum model. Here the water availability at any farm Z(xj) is a joint spatio-temporal environment and socioeconomic process. Water availability is estimated using spatial econometric tool. Here the spatial weight matrix (W) is constructed by taking water user associations (WUA) as boundaries. The choice of a crop is explained using spill over model in which the choice of a crop is influenced by the choice of neighbouring farmers. Here the spatial lag model is modified to adapt the latent variable (y*) which has a binary outcome.

description: Evidence for the central engine of gamma-ray bursts (GRBs) has been collected in the Neil Gehrels \emph{Swift} data. For instance, some GRBs show an internal X-ray plateau followed by very steep decay, which is difficult to be interpreted within the framework of a black hole (BH) central engine, but are consistent within a rapidly spinning magnetar engine picture. The very steep decay at the end of the plateau suggests a sudden cessation of the central engine, which is explained as the collapse of a supra-massive magnetar into a black hole when it spins down. Here we propose that some additional evidence, such as a second X-ray plateau feature would show up, if the fall-back accretion could activate the newborn BH and sufficient energy could be transferred from the newborn BH to the GRB blast wave. With a systematic data analysis for all long GRBs, we find three candidates in \emph{Swift} sample, i.e., GRBs 070802, 090111, and 120213A, whose X-ray afterglow light curves contain two plateaus, with the first one being an internal plateau. We find that in a fairly loose and reasonable parameter space, the second X-ray plateau data for all 3 GRBs could be well interpreted with our proposed model. Future observations are likely to discover more similar events, which could offer more information of the properties of the magnetar as well as the newborn BH.

Polarization in charmless $B \to VV$ decays

description: Recent data for B decays to two light vector mesons show that the longitudinal amplitude dominates in $B^0 \to ρ^+ ρ^-$, $B^+ \to ρ^+ ρ^0$, $ρ^0 K^{*+}$ decays and not in $B^0 \to ϕK^{*0}$, $B^+ \to ϕK^{*+}$. We consider rescattering mediated by charmed resonances, finding that in $B \to ϕK^*$ it can be responsible of the suppression of the longitudinal amplitude. A similar result is found for $B \to ρK^{*}$.

Subjects: subject: Mathematical physics

description: This document presents a comprehensive paradigm that unifies con-cepts of resonance and emergence to bridge holistic and reductionist ap-proaches. By integrating established mathematical models with holisticprinciples, we propose a framework that offers new insights into phenom-ena across physics, neuroscience, and other disciplines. We demonstratethis framework using coupled harmonic oscillators and the Kuramotomodel [1][2], comparing results with known solutions to validate its ef-fectiveness. This paradigm aims to foster interdisciplinary collaborationand provide a foundation for professionals to explore and expand uponthese ideas.

description: Important changes took place in agricultural policies in Europe in the 19th and 20th century. The dramatic nature of the changes are illustrated by two years, a century apart: 1860 and 1960. In the 1860s European nations agree on a series of trade agreements which spread free trade across the continent. In the 1960s European nations conclude an international agreement which spreads heavy government intervention and protection against imports across the continent. This paper reviews the nature and the causes of these dramatic changes in agricultural and trade policies, from the beginning of the 19th century to the second half of the 20th century, when agricultural policies are integrated in (what is to become) the European Union.

description: A series of gravitational instabilities in a circumnuclear gas disk (CND) are required to trigger gas transport to a central supermassive black hole (SMBH) and ignite Active Galactic Nuclei (AGNs). A test of this scenario is to investigate whether an enhanced molecular gas mass surface density ($Σ_{\rm mol}$) is found in the CND-scale of quasars relative to a comparison sample of inactive galaxies. Here we performed sub-kpc resolution CO(2-1) observations with ALMA of four low-redshift ($z \sim 0.06$), luminous ($\sim 10^{45}$ erg s$^{-1}$) quasars with each matched to a different star-forming galaxy, having similar redshift, stellar mass, and star-formation rate. We detected CO(2-1) emission from all quasars, which show diverse morphologies. Contrary to expectations, $Σ_{\rm mol}$ of the quasar sample, computed from the CO(2-1) luminosity, tends to be smaller than the comparison sample at $r < 500$ pc; there is no systematic enhancement of $Σ_{\rm mol}$ in our quasars. We discuss four possible scenarios that would explain the lower molecular gas content (or CO(2-1) luminosity as an actual observable) at the CND-scale of quasars, i.e., AGN-driven outflows, gas-rich minor mergers, time-delay between the onsets of a starburst-phase and a quasar-phase, and X-ray-dominated region (XDR) effects on the gas chemical abundance and excitation. While not extensively discussed in the literature, XDR effects can have an impact on molecular mass measurements particularly in the vicinity of luminous quasar nuclei; therefore higher resolution molecular gas observations, which are now viable using ALMA, need to be considered.

description: Opfer sexueller Gewalt erleiden einen massiven Eingriff in ihre persönliche Entwicklung. Dieses Trauma zu bewältigen und als Erfahrung zu integrieren ist eine gewaltige Herausforderung für die Betroffenen. Die vorliegende Arbeit beschäftigt sich nicht primär mit der Grausamkeit "sexuellen Missbrauchs" und den Folgen für die Betroffenen, sondern zeigt individuelle Wege der Verarbeitung traumatisierender Erfahrungen. Nach einer Einführung in die Psychotraumatologie werden Dimensionen sexueller Gewalt beleuchtet. In der Auseinandersetzung mit Bewältigungsressourcen der Betroffenen werden die theoretischen Konzepte der Salutogenese, der Schutzfaktoren und Copingstrategien diskutiert. Die individuellen Bewältigungsstrategien werden in Interviews mit Frauen anschaulich, die von sexueller Gewalt betroffen sind. Eine kompetente Unterstützung durch die Soziale Arbeit wird nur dann gelingen können, wenn sie der ressourcenorientierten Perspektive folgt, wie sie hier von Sabine Lakota entwickelt wird.

description: We present an active control scheme of a kinetic model of swarming. It has been shown previously that the global control scheme for the model, presented in \cite{JK04}, gives rise to spontaneous collective organization of agents into a unified coherent swarm, via a long-range attractive and short-range repulsive potential. We extend these results by presenting control laws whereby a single swarm is broken into independently functioning subswarm clusters. The transition between one coordinated swarm and multiple clustered subswarms is managed simply with a homotopy parameter. Additionally, we present as an alternate formulation, a local control law for the same model, which implements dynamic barrier avoidance behavior, and in which swarm coherence emerges spontaneously.

description: McCartney rose is a range management problem on 500,000 acres of rangeland in Texas. Roller chopping followed by burning is an effective method of improving infested rangeland. However, uncertainty associated with implementing effective burns adversely affects economic feasibility of the treatment sequence. Discrete stochastic programming is used to determine optimal burning schedules under uncertainty. Optimal schedules and expected net returns vary with changes in the probability of a successful burn.

description: The monthly and quarterly price determination processes for 31-40 and 21-25 size classes of raw-headless shrimp were examined to determine price leadership between market levels. Causal relationships were assessed using Haugh-Pierce, Sims, and Granger methods. Price models at the retail, wholesale, and exvessel market levels were estimated. Economic factors analyzed were income, prices of competing products, landings and imports of raw headless shrimp, total retail supply, beginning stocks, and marketing costs. Monthly prices generally exhibited unidirectional causality from exvessel to retail price. Quarterly prices were determined interdependently among market levels. Price responses between market levels were found to by symmetric with beginning stocks, landings, and imports of own-size shrimp the most important determinants of price.

description: We derive a partial electric-magnetic (PEM) duality transformation of the twisted quantum double (TQD) model TQD$(G,α)$---discrete Dijkgraaf-Witten model---with a finite gauge group $G$, which has an Abelian normal subgroup $N$, and a three-cocycle $α\in H^3(G,U(1))$. Any equivalence between two TQD models, say, TQD$(G,α)$ and TQD$(G',α')$, can be realized as a PEM duality transformation, which exchanges the $N$-charges and $N$-fluxes only. Via the PEM duality, we construct an explicit isomorphism between the corresponding TQD algebras $D^α(G)$ and $D^{α'}(G')$ and derive the map between the anyons of one model and those of the other.

description: Animals have evolved distinctive survival strategies in response to constant selective pressure. In this review, we highlight how animals exploit complex flow phenomena by manipulating their habitat or by producing complex fluids. In particular, we outline different strategies evolved for movement, defense from predators, attacking of prey, and reproduction and breeding. From the slimy defense of the notorious hagfish to the circus-like mating spectacle of leopard slugs, we unveil remarkable correlations within the flow behavior and biological purpose of biological complex fluids. We discuss recurring phenomena, propose flow behavior for undescribed complex fluids, and put these in context with the animals survival strategy. With this review, we hope to underline the importance of complex fluids and material flow in the animal kingdom.

description: The polarization observed for stars background to dark clouds (Bok Globules) is often used as diagnostic to study the ongoing star formation processes in these clouds. Such polarization in the optical have been reported for eight nearby clouds CB3, CB25, CB39, CB52, CB54, CB58, CB62 and CB246 in one of our previous work (Sen et. al. 2000). With a view to understand the origin of this polarization, the the present work attempts are made to look for any possible relation between this observed polarization and other physical parameters in the cloud (like temperature, turbulence etc.). The observed polarization does not seem to be clearly related to the dust and gas temperatures (T_d and T_g) in the cloud as expected from the Davis-Greenstein grain alignment mechanism (Davis & Greenstein, 1952). However, the average observed polarization p_av appears to be related to the turbulence delta V (measured by 12CO line width) by the mathematical relation p_av=2.95exp(-0.24delta V). The possible realtion between the direction of polarization vector and other physical parameters are also discussed. For this analysis, in addition to the data on above eight clouds, the data on CB4 (Kane et. al., 1995) are also included for comparison.

Subjects: Productivity Analysis

description: Previous research found a positive relationship between concentration and total factor productivity in food manufacturing. On industry (i.e., meatpacking plants [SIC 2011]) was selected for independent analysis due to a relatively sharp increase in concentration in recent years. The methodology chosen was similar to previous studies. Total factor productivity increased 2.4 percent per year, and labor productivity increased 3.3 percent per year for meatpacking plants over the 1958-82 period. Concentration in meatpacking did not positively or negatively affect total factor productivity or labor productivity over the 25-year study period.

description: Non-collinear magnetic order arises for various reasons in several magnetic systems and exhibits interesting spin dynamics. Despite its ubiquitous presence, little is known of how magnons, otherwise stable quasiparticles, decay in these systems, particularly in metallic magnets. Using inelastic neutron scattering, we examine the magnetic excitation spectra in a metallic non-collinear antiferromagnet CrB$_{2}$, in which Cr atoms form a triangular lattice and display incommensurate magnetic order. Our data show intrinsic magnon damping and continuum-like excitations that cannot be explained by linear spin wave theory. The intrinsic magnon linewidth $Γ(q,E_{q})$ shows very unusual momentum dependence, which our analysis shows to originate from the combination of two-magnon decay and the Stoner continuum. By comparing the theoretical predictions with the experiments, we identify where in the momentum and energy space one of the two factors becomes more dominant. Our work constitutes a rare comprehensive study of the spin dynamics in metallic non-collinear antiferromagnets. It reveals, for the first time, definite experimental evidence of the higher-order effects in metallic antiferromagnets.

description: Naïve and adaptive schemes have been used as proxies for price expectations in previous studies of supply response. Those studies contain mixed formulas of futures, support, and lagged prices as alternative formulations for price expectations. This study uses a conditional expected price which combines both market and support prices into one price expectations measure. It defines the total effect of available information on supply response. The results indicate the potential usefulness of formulating expected prices as conditional price expectations in supply response analysis, with support prices being the conditional set. Under the provisions of the 1985 Farm Bill, significant reductions in corn and soybean acreages are in prospect for 1987-90.

description: This article proposes a Novel Nonlinear Model Predictive Control (NMPC) for navigation and obstacle avoidance of an Unmanned Aerial Vehicle (UAV). The proposed NMPC formulation allows for a fully parametric obstacle trajectory, while in this article we apply a classification scheme to differentiate between different kinds of trajectories to predict future obstacle positions. The trajectory calculation is done from an initial condition, and fed to the NMPC as an additional input. The solver used is the nonlinear, non-convex solver Proximal Averaged Newton for Optimal Control (PANOC) and its associated software OpEn (Optimization Engine), in which we apply a penalty method to properly consider the obstacles and other constraints during navigation. The proposed NMPC scheme allows for real-time solutions using a sampling time of 50 ms and a two second prediction of both the obstacle trajectory and the NMPC problem, which implies that the scheme can be considered as a local path-planner. This paper will present the NMPC cost function and constraint formulation, as well as the methodology of dealing with the dynamic obstacles. We include multiple laboratory experiments to demonstrate the efficacy of the proposed control architecture, and to show that the proposed method delivers fast and computationally stable solutions to the dynamic obstacle avoidance scenarios.

description: This study evaluates the economic survivability of rice farms in the Delta area of Mississippi. A general whole-farm simulation model, FLIPSIM V, is used to simulate the operations of representative rice farms over a 10-year period. Although farm size did not change for any of the representative farms considered, the financial structure of these farms changed considerably. Crop mix was found to cause significant differences in the economic growth and financial viability of rice farms in the region.

description: Using input-output tables for 1972 and 1977 we examine direct and indirect energy use in the production of fourteen U.S. agricultural products. We find that between 1972 and 1977 energy use increased in absolute terms but decreased in terms of Btus required per dollar of output. Although this trend is encouraging in terms of the long-run ability of U.S. agriculture to adjust to higher energy prices, the following caveats should be mentioned; (1) a large part of the decrease in primary energy intensity is attributable to one sector, meat animals, (2) there was a substantial increase in electricity intensity in almost all sectors, and (3) there was an increase in the use of energy embodied in fertilizers and agricultural chemicals in the very important food grain and feed sectors.
title: Competitive Intelligence : Aufbau einer Informationsbasis und Entscheidungssystematik zur Definition strategischer Zielmärkte

Subjects: subject: 650 Management

description: Im Rahmen der Globalisierung und des daraus resultierenden Wettbewerbs ist es für ein Unternehmen von zentraler Bedeutung, Wissen über die Wettbewerbssituation zu erhalten. Nicht nur zur Erschließung neuer Märkte, sondern auch zur Sicherung der Unternehmensexistenz ist eine Wettbewerbsanalyse unabdingbar. Konkurrenz- bzw. Wettbewerbsforschung wird überwiegend als „Competitive Intelligence“ bezeichnet. In diesem Sinne beschäftigt sich die vorliegende Bachelorarbeit mit einem Bereich von Competitive Intelligence. Nach der theoretischen Einführung in das Thema werden die Ergebnisse von neun Experteninterviews sowie einer schriftlichen Expertenbefragung innerhalb des Unternehmens erläutert. Die Experteninterviews und -befragungen zum Thema Competitive Intelligence dienten zur Entwicklung eines neuen Wettbewerbsanalysekonzeptes. Die Experteninterviews zeigten, dass in dem Unternehmen kein einheitliches Wettbewerbsanalysesystem existiert und Analysen lediglich ab hoc getätigt werden. Zusätzlich wird ein Länderranking vorgestellt, das zur Analyse europäischer Länder für das Unternehmen entwickelt wurde. Die Ergebnisse zeigten, dass Dänemark und Italien für eine Ausweitung der Exportgeschäfte bedeutend sind. Der neu entwickelte Mitbewerberbewertungsbogen wurde auf Grundlage dieser Ergebnisse für Dänemark und Italien getestet.
description: Within the context of globalisation and ensuing competition, it is of utmost importance that a company keep itself informed of the competitive situation. A competitive analysis is indispensable, not only for opening up new markets, but also for safeguarding the future of the business. Business competition or competitive research is largely referred to as "competitive intelligence". It is in this sense that the present Bachelor thesis concerns itself with an area of competitive intelligence. After a theoretical introduction on the subject, the findings of nine expert interviews, as well as one written, in-company expert survey are outlined. The expert interviews and surveys on competitive intelligence played a role in the development of a new competitive analysis concept. The expert interviews showed that there is no unified competitive analysis system within the company and that analyses take place on a merely ad-hoc basis. A country ranking, which has been developed for the company's analysis of European countries, is also presented. The findings showed that Denmark and Italy are important for the expansion of export sales. The newly developed competitor evaluation sheet was tested based on these findings concerning Denmark and Italy.
