description: La lutte contre P. solanacearum dans toutes les régions tropicales demeure particulièrement difficile en raison du caractère tellurique et vasculaire de cette bactérie. En Guadeloupe et en Martinique, la lutte a été concue de façon intégrée, en conjuguant les connaissances et ressources acquises en - Pathologie Végétale ; caractérisation et agressivité des souches de race 1 (biovar I et III), détection précoce par ELISA des plants porteurs sains, survie réduite aux potentiels hydriques élevés dans les vertisols de Grande- Terre, - Amélioration des Plantes ; sélection de variétés résistantes de tomate ("Caraïbo") et d'aubergines (familles SAM et SAF), - Agronomie ; diminution de la réceptivité des oxisols par fertilisations azotées (750 uN.ha-1), - Science du Sol ; conséquences de la microstructuration des sols sur l'expression de P. solanacearum. Les recherches menées dans différentes situations pédologiques et agronomiques permettent d'envisager une production régulière. ----- P. solanacearum is a soil-borne and a xylem invading bacterium, therefore it is especially difficult to bring this tropical world-wide disease under control. In Guadeloupe and Martinique we attempted to develop integrated control by joining up knowledges and resources acquired with : - Phytopathology ; characterization and aggressiveness of race 1 (biovar I and 111) strains, early detection of latent infections in tomatoes with an ELISA test, rapid decline of bacteria in natural vertisols (Grande-Terre) when maintained at high water potential, - Plant breeding ; selection of bacterial wilt resistant tomato line (Caraïbo) and family of eggplants (SAM and SAF), - Agronomy ; nitrogen fertilising (750 uN.ha-1) resulted in a considerable decrease of oxysol receptivity to the disease. - Soil science, outcome of soil network on P. solanacearum expression. Experimentations conducted in different pedological and agronomical conditions shows it is possible to obtain regular vegetable productions.

description: Shot noise processes have been extensively studied due to their mathematical properties and their relevance in several applications. Here, we consider nonnegative shot noise processes and prove their weak convergence to Lévy-driven Ornstein-Uhlenbeck (OU), whose features depend on the underlying jump distributions. Among others, we obtain the OU-Gamma and OU-Inverse Gaussian processes, having gamma and inverse gaussian processes as background Lévy processes, respectively. Then, we derive the necessary conditions guaranteeing the diffusion limit to a Gaussian OU process, show that they are not met unless allowing for negative jumps happening with probability going to zero, and quantify the error occurred when replacing the shot noise with the OU process and the non-Gaussian OU processes. The results offer a new class of models to be used instead of the commonly applied Gaussian OU processes to approximate synaptic input currents, membrane voltages or conductances modelled by shot noise in single neuron modelling.

description: We present a second-order accurate numerical method for a class of nonlocal nonlinear conservation laws called the "nonlocal pair-interaction model" which was recently introduced by Du, Huang, and LeFloch. Our numerical method uses second-order accurate reconstruction-based schemes for local conservation laws in conjunction with appropriate numerical integration. We show that the resulting method is total variation diminishing (TVD) and converges towards a weak solution. In fact, in contrast to local conservation laws, our second-order reconstruction-based method converges towards the unique entropy solution provided that the nonlocal interaction kernel satisfies a certain growth condition near zero. Furthermore, as the nonlocal horizon parameter in our method approaches zero we recover a well-known second-order method for local conservation laws. In addition, we answer several questions from the paper from Du, Huang, and LeFloch concerning regularity of solutions. In particular, we prove that any discontinuity present in a weak solution must be stationary and that, if the interaction kernel satisfies a certain growth condition, then weak solutions are unique. We present a series of numerical experiments in which we investigate the accuracy of our second-order scheme, demonstrate shock formation in the nonlocal pair-interaction model, and examine how the regularity of the solution depends on the choice of flux function.

description: Die Konferenz von Seelisberg/Schweiz (1947) gilt als Gründungsakt des jüdisch-christlichen Dialogs in Europa nach der Schoah. Der Autor führt mit seiner Luzerner Dissertation (2019; kultur-und sozialwissen-schaftliche Fakultät der Universität Luzern) in die Hintergründe, Entstehensbedingungen und Nachwirkungen dieser Konferenz ein, deren Hauptanliegen die Bekämpfung des Antisemitismus war. Die Entstehung des institutionellen jüdisch-christlichen Dialogs in der Schweiz und in Kontinentaleuropa nachzuzeichnen ist Thema des Buches. Jehoshua Ahrens hat mit seiner Doktorarbeit einen bislang weißen Fleck in der Forschung zum institutionellen jüdisch-christlichen Dialog geschlossen, indem er sich mit der Entstehung und Wirkung der sog. Zehn Seelisberger Thesen von 1947 beschäftigt hat. Die Dissertation ist äußerst sachkundig und historisch präzise geschriebenund das Anliegen von Jehoshua Ahrens deutlich hervorgehoben, die Seelisberger Thesen nicht nur historisch zu betrachten, sondern sie auch im aktuellen Kampf gegen den gegenwärtigen Antisemitismus argumentativ einzusetzen.

description: We have experimentally studied the unstable dynamics of a harmonically trapped Bose-Einstein condensate loaded into a 1D moving optical lattice. The lifetime of the condensate in such a potential exhibits a dramatic dependence on the quasimomentum state. This is unambiguously attributed to the onset of dynamical instability, after a comparison with the predictions of the Gross-Pitaevskii theory. Deeply in the unstable region we observe the rapid appearance of complex structures in the atomic density profile, as a consequence of the condensate phase uniformity breakdown.

description: Une enquête réalisée par le Service de la Protection des végétaux de la Martinique et le GRISP Antilles Guyane, révèle l'existence de quelques problèmes phytosanitaires majeurs sur la culture de la tomate aux Antilles Françaises, qui en entrave son intensification. En plus de Pseudomonas solanacearum, Erwinia chrysanthemi et Erwinia carotovora sont connus depuis peu comme d'autres agents bactériens de flétrissement. L'impact des nématodes se limite essentiellement à un affaiblissement de la plante. La mouche mineuse Liriomyza sativae, Xanthomonas campestris pv. vesicatoria agent de la gale bactérienne, les acariens (Eryophiidae et Tétranyques) ainsi que localement des virus (CMV, TMV, PVY), constituent les causes les plus importantes d'altération des parties aériennes. L'amélioration de cette situation passe entre autre par un effort important de formation auprès des maraîchers. ----- An inquiry, conducted by the «Service de la Protection des Végétaux» in Martinique, and GRISP Antilles Guyane, could identify the major phytosanitary problems on tomatoes in the French West Indies. All these problems impede the expansion of tomato production. Erwinia chrysanthemiand Erwinia carotovora are identified as causes of wilt, in addition to Pseudomonas solanacearum. Nematodes are only a cause of weakening for plants. Leaf miners Liriomyza sativae, bacterial spot,( causal agent : Xanthomonas campestris pv. vesicatoria), mites (Eryophiidaeand Tetranyques) and (locally) virus diseases (CMV, TMV, PVY), are the most important causes of disorders on aerials parts. An important work, in order to improve grower's technical nature, will be necessary ability to obtain a better phytosanitary situation.

description: Optimizing traffic flow is essential for easing congestion. However, even when globally-optimal, coordinated and individualized routes are provided, users may choose alternative routes which offer lower individual costs. By analyzing the impact of selfish route-choices on performance using the cavity method, we find that a small ratio of selfish route-choices improves the global performance of uncoordinated transportation networks, but degrades the efficiency of optimized systems. Remarkably, compliant users always gain in the former and selfish users may gain in the latter, under some parameter conditions. The theoretical results are in good agreement with large-scale simulations. Iterative route-switching by a small fraction of selfish users leads to Nash equilibria close to the globally optimal routing solution. Our theoretical framework also generalizes the use of the cavity method, originally developed for the study of equilibrium states, to analyze iterative game-theoretical problems. These results shed light on the feasibility of easing congestion by route coordination when not all vehicles follow the coordinated routes.

description: This paper investigates the possible role played by the Common Agricultural Policy (CAP) Fischler Reform on the agricultural GHG emissions at the farm level. The empirical analysis concerns a balanced panel of Italian Farm Accountancy Data Network farms observed over years 2003-2007. Multinomial Logit models are estimated in sequence to express how the farm level emissions (and the respective production choices) vary over time also in response to CAP expenditure. Results suggest that CAP expenditure had a role in the evolution of the farm-level emissions, though the direction of this effect may differ across farms and deserves further investigation.

description: This paper compares technical efficiencies (TEs) and technological gap ratios (TGRs) for dairy farms in the Norwegian regions accounting for differences in working environments. We used the 'true' random effect model of Greene (2005) and the stochastic metafrontier approach by Huang et al. (2014) to estimate TEs and TGRs. The dataset used was farm-level balanced panel data for 23 years (1992-2014) with 5442 observations from 731 dairy firms. The results of the analysis provide empirical evidence of small regional differences in technical efficiencies, technological gap ratios, and input use. Thus, an assumption about joint underlying technology across regions seems to be quite reasonable, since our results implies that the policies in place are working effectively to keep relatively disadvantaged producers in the business. Further, the results may provide some support for the more region-specific agricultural policies, in terms of support schemes and structural regulations.

The pendulum, with a measured torque noise floor below 10 fNm/sqrt{Hz} from 0.6 to 10 mHz, has allowed placement of an upper limit on sensor force noise contributions, measurement of the sensor electrostatic stiffness at the 5% level, and detection and compensation of stray DC electrostatic biases at the mV level.

description: The aim in this paper is to investigate economies of scale and scope among Norwegian dairy and crop producing farms, controlling for regional differences. Unlike previous studies in which a common technology was assumed, we estimate economies of scale and scope to account for different technologies for specialized and mixed (diversified) farms. Our analysis is based on translog cost functions using farm-level data for the period 1991-2014. The results suggest that both economies of scale and scope persist in Norwegian dairy and crop producing farms. We also find that dairy farms have an economic incentive to integrate dairy farming with crop production in all regions of Norway.

description: Several studies, focused on the understanding of price volatility determinants in agricultural commodity markets, revealed that the joint influence of a plethora of causes is able to generate market instability. We investigate the contribution of endogenous and exogenous factors to global price volatility of four major grain (wheat, rice, corn, barley), adopting a Seemingly Unrelated Regression Equations model. We analyze global volatility, to conclude on short-run and long-run dynamics of markets instability. Our paper builds on existing literature by proposing a richer set of determinants of grain price volatility.

Random periodic paths through random attractors, synchronizations and Lyapunov exponents

Subjects: subject: 19999 Mathematical Sciences not elsewhere classified

description: In this thesis, we discuss the existence of random periodic paths through studying random periodic attractors and synchronization of stochastic periodic semi-flows. We define a random periodic attractor as an invariant set attracting all trajectories when time goes to infinity. We prove the existence of random periodic attractors for stochastic periodic semi-flows and give conditions to enable a random periodic attractor to be a singleton which means that stochastic periodic semi-flows become synchronized. Then synchronization of stochastic periodic semi-flows can imply the existence of random periodic path. We also apply our results in Benzi–Parisi–Sutera–Vulpiani’s stochastic differential equation and use some numerical methods to compute Lyapunov exponents. Finally with the help of the idea of random attractors and Lyapunov exponents, we find the existence of the random periodic path of this equation.

description: This survey used data from the East Africa Dairy Development project which utilizes farmer based organizations to evaluate whether producer organizations have been efficiently used by the project to impact on inputs use and income. Propensity score matching results show that project participants generated higher dairy revenues than non-participants. They also spent more on hired labour and animal breeding and had a higher probability of having improved breeds. The findings have important implications for development agents and policy makers seeking productivity improvement and increased market participation of poor smallholder dairy farmers as establishment and growth of producer organizations.

description: The spatial dimension of the raw milk market facilitates the exercise of oligopsonistic power of milk processors towards farmers. At the same time, the market is characterised by a high share of processing cooperatives (coops). Hence, coops compete with investor-owned firms (IOFs) in a mixed market. Assuming uniform delivered pricing, we theoretically analyse spatial competition in a mixed market. Our theoretical and empirical results for Bavarian milk processors confirm the so-called “competitive yardstick effect”, i.e. coops can mitigate the oligopsony power of IOFs. In our theoretical model, the strength of this effect depends on the behaviour of IOFs.

description: Agricultural cooperatives in post-socialistic countries often fail to justify their purpose. Lack of trust and social capital are plausible reasons. The aim of this paper is to map the relationship structure of farmers in region where operational cooperative exists. The Social network analysis demonstrates low levels of social capital however, the cooperative acts as valuable information provider for its members, serving as information mediator to the rural development program’s resources, required for farmers’ investment initiatives. This is a positive evidence for small-scale farmers and a step forward in motivating changes of farmer’s attitudes towards cooperation and re-establishment of agricultural cooperatives.
Fermentation kinetics including product and substrate inhibitions plus biomass death: a mathematical analysis

description: Fermentation is generally modelled by kinetic equations giving the time evolutions for biomass, substrate, and product concentrations. Although these equations can be solved analytically in simple cases if substrate/product inhibition and biomass death are included, they are typically solved numerically. We propose an analytical treatment of the kinetic equations --including cell death and an arbitrary number of inhibitions-- in which constant yield needs not be assumed. Equations are solved in phase space, i.e. the biomass concentration is written explicitly as a function of the substrate concentration.

description: We show that in superfluids with fermionic imbalance and uniform ground state, there are stable solitons. These solutions are formed of radial density modulations resulting in nodal rings. We demonstrate that these solitons exhibit nontrivial soliton-soliton and soliton-vortex interactions and can form complicated bound states in the form of "soliton sacks". In a phase-modulating (Fulde-Ferrell) background, we find different solitonic states, in the form of stable vortex-antivortex pairs.

Electric transport and magnetism in the Heusler systems Pd2MnIn, Fe2MnSi and Fe2VSi under pressure

description: High pressure transport and magnetic measurements have been undertaken on the full Heusler alloys Pd2MnIn, Fe2MnSi and Fe2VSi.
 In Pd2MnIn a change in the resistivity of the sample is observed, as gradually a peak appears under pressure. The phenomenon has been analyzed through a high temperature variable range hopping conduction. Alternatively, following some magnetic measurements that showed a difference between the ZFC and FC magnetization curves, the resistivity results were interpreted as a competition between the Kondo effect and the RKKY (Ruderman-Kittel-Kasuya-Yosida) interactions in the system, a phenomenon observed in some spin glass systems.
 In Fe2MnSi, both the high pressure resistivity and the high pressure magnetic measurements point to a weak increase in the two magnetic transition temperatures. In addition, at low temperatures we observe a minimum in resistivity. The magnitude and the temperature of the minimum increases with pressure.
 In Fe2VSi we provide some evidence, based on high pressure electric and thermoelectric transport measurements, of a possible pressure induced suppression of the structural transition that is present in the system at ambient pressure. The results are discussed in relation to an earlier theoretical study on the system.

description: We use coupled-cluster theory and nuclear interactions from chiral effective field theory to compute the nuclear matrix element for the neutrinoless double-beta decay of $^{48}$Ca. Benchmarks with the no-core shell model in several light nuclei inform us about the accuracy of our approach. For $^{48}$Ca we find a relatively small matrix element. We also compute the nuclear matrix element for the two-neutrino double-beta decay of $^{48}$Ca with a quenching factor deduced from two-body currents in recent ab-initio calculation of the Ikeda sum-rule in $^{48}$Ca [Gysbers et al., Nature Physics 15, 428-431 (2019)].

The effects of bone mineral density testing on health related behaviours in a randomly selected population of Canadians
Creators: name: Kingwell, Elaine
Publisher: name: University of British Columbia
Year: 2011

description: Osteoporosis is a major health problem that can be mitigated by accurate prediction of future risk for bone fractures. Bone mineral density (BMD) testing can be conducted to assess people's risk of fracture, but its value rests on the ability to provide risk information effectively to those individuals who have low BMD; those individuals must then be willing to initiate and maintain recommended lifestyle behaviours and medications. This study assessed the influence of low BMD results and direct-to-participant feedback of results on awareness of diagnosis, information seeking about osteoporosis, bone-related medication use and health behaviours. Participants included 1,837 women and 869 men aged 40-60 years, from the population-based prospective Canadian Multicentre Osteoporosis Study, who had undergone baseline dual energy X-ray absorptiometry of the hip and spine. Bone-related health behaviour, medication use and risk factors for osteoporosis were measured by questionnaire at baseline and at 3-year follow-up; recall of BMD test results and subsequent information seeking were assessed at Year 3. The diagnosis reported to the participant and/or the family physician, was documented retrospectively by review of the feedback reports. Correct recall of osteoporosis or osteopenia diagnoses was poor, particularly in men. After adjustment for baseline health behaviour and other important covariates, low BMD results at baseline were associated with subsequent information seeking, and with higher calcium intake, Vitamin D supplement use and osteoporosis-related medication use at follow-up. A report of low BMD had no influence on exercise participation, smoking cessation, high alcohol consumption, or high caffeine intake. Direct-to-participant feedback v. feedback only to the physician was associated with increased awareness of diagnosis in those with a borderline or normal diagnosis, greater information seeking, and calcium supplementation in women and men, and increased exercise participation and reduced caffeine consumption in women. Educational strategies that specifically target men and specific interventions to support health behaviour change in those at increased risk of fracture are likely to be necessary if BMD testing in this age-group is to have a significant impact on fracture risk. Direct-to-participant feedback may offer an effective method of increasing awareness of BMD test results and influencing some health behaviours.

description: This article discusses aeroacoustic imaging methods based on correlation measurements in the frequency domain. Standard methods in this field assume that the estimated correlation matrix is superimposed with additive white noise. In this paper we present a mathematical model for the measurement process covering arbitrarily correlated noise. The covariance matrix of correlation data is given in terms of fourth order moments. The aim of this paper is to explore the use of such additional information on the measurement data in imaging methods. For this purpose a class of weighted data spaces is introduced, where each data space naturally defines an associated beamforming method with a corresponding point spread function. This generic class of beamformers contains many well-known methods such as Conventional Beamforming, (Robust) Adaptive Beamforming or beamforming with shading. This article examines in particular weightings that depend on the noise (co)variances. In a theoretical analysis we prove that the beamformer, weighted by the full noise covariance matrix, has minimal variance among all beamformers from the described class. Application of the (co)variance weighted methods on synthetic and experimental data show that the resolution of the results is improved and noise effects are reduced.

Mobbingprävention
Mobbing
Masterarbeit

description: Durch die zunehmende Digitalisierung und den hohen Leistungsdruck in Schule und Gesellschaft wird Mobbing laut jüngster PISA Studie aus dem Jahr 2019 zu einem immer präsenteren Thema. Die Auswirkungen hinterlassen bleibende Schäden bei den Opfern und können von Ängsten und Depressionen bis hin zum Suizid führen. Opfer eines Mobbings kann jede Person werden, denn jede Andersartigkeit kann als Schwäche interpretiert und von einer Gruppe abgelehnt werden. Dies betrifft insbesondere auch Kinder und Jugendliche der integrativen Schule, die sich durch ihren Hintergrund und ihre Biografie häufig von den Lernenden der Regelklasse unterscheiden. Mobbing in der Schule stellt Betroffene vor eine grosse Herausforderung. Zum einen geschehen die Mobbingübergriffe meist im Versteckten, was sie schwer erkennbar macht. Zum anderen benötigt man fundiertes Fachwissen und ausreichende Ressourcen, um eine Mobbingsituation erfolgreich auflösen zu können. Nicht selten gibt es intervenierende Personen, die dabei Unsicherheiten zeigen und nur unzureichend über Handlungsmöglichkeiten Bescheid wissen.
 Die Frage, wie man Mobbing erkennen, mit geeigneten Handlungsschritten einschreiten und präventiv solche Übergriffe verhindern kann, bildet die zentrale Frage der vorliegenden Masterarbeit. Um diese zu beantworten, wurde auf Basis einer Bedarfsanalyse mittels Gruppeninterviews sowie der Auseinandersetzung mit der Theorie ein Leitfaden erstellt. Der Einsatz dieses Instruments soll helfen, Mobbing frühzeitig zu erkennen und professionell darauf reagieren zu können. Der entwickelte Leitfaden wurde mit denselben Interviewgruppen kommunikativ validiert. Basierend auf den Aussagen des Gruppeninterviews und der Theorie wurde der Leitfaden modifiziert.
 Die Ergebnisse der Interviews zeigen deutlich, dass Mobbing im Schulalltag schwierig zu erkennen ist. Es bestehen viele Unsicherheiten, wie professionell mit Mobbing umgegangen werden kann. Die Wünsche der Interviewteilnehmer*innen in Hinsicht auf Mobbingprävention und -intervention waren vielfältig und reichten von Weiterbildungen bis hin zu Austauschmöglichkeiten und Kontaktadressen von Beratungsstellen. Die präventive Arbeit in der Volksschule sei ihrer Ansicht nach wichtig, damit ein angstfreies Lernumfeld geschaffen werden könne.
