description: We present an algebraic method for treating molecular vibrations in the Morse potential perturbed by an external laser field. By the help of a complete and normalizable basis we transform the Schrödinger equation into a system of coupled ordinary differential equations. We apply our method to calculate the dissociation probability of the NO molecule excited by chirped laser pulses. The dependence of the molecular dipole-moment on the interatomic separation is determined by a quantum-chemical method, and the corresponding transition dipole moments are given by approximate analytic expressions. These turn out to be very small between neighboring stationary states around the vibrational quantum number $m=42$, therefore we propose to use additional pulses in order to skip this trapping state, and to obtain a reasonable dissociation probability.

description: In light of the mounting evidence that the highest energy cosmic rays are dominated by protons and not gamma-rays, we discuss the prospect that these cosmic rays are generated in the decay or annihilation of superheavy relic particles. We calculate the high energy neutrino spectrum which results and normalize our results to the ultra-high energy cosmic ray spectrum. We show that most scenerios are already constrained by present limits placed by the AMANDA experiment.

description: Anhand einer Feldstudie mit Rekruten der Schweizer Armee werden verschiedene psychologische Faktoren bezüglich ihrer Wirkung als Determinanten für die Bewältigung von Situationen mit erhöhter Stressbelastung untersucht. Die militärische Grundausbildung (Rekrutenschule) stellt einen strukturierten, hierarchischen Kontext dar, der basierend auf den zivilen Sozialisationserfahrungen eine überdurchschnittlich grosse Anpassungsleistung erfordert. Die Fragestellungen dieser Arbeit beziehen sich sowohl auf den Einfluss von Motivation, Einstellung und Erwartung auf das erfolgreiche Bestehen der Rekrutenschule (Aufgabenerfüllung) als auch auf die Zusammenhänge dieser Faktoren mit der psychischen Befindlichkeit während dieser Tätigkeit. Dabei wird insbesondere die Rolle der allgemeinen Selbstwirksamkeitserwartung vertieft analysiert. Die untersuchte Stichprobe (N = 328) setzt sich aus gesunden Männern im Alter zwischen 19 und 21 Jahren zusammen. Das Studiendesign beinhaltet drei Messzeitpunkte, wobei die gesundheitsbezogenen abhängigen Variablen mehrfach anhand von bestehenden Messinstrumenten erhoben wurden. Die Skalen zur Erfassung von Motivation, Einstellung und Erwartungen wurden eigens für diese Studie entwickelt. Die berichteten gesundheitsbezogenen Belastungen der Rekruten sind, den hohen körperlichen und psychischen Anforderungen der militärischen Grundausbildung entsprechend, relativ stark ausgeprägt und bewegen sich deutlich über der vergleichbaren Altersnorm. Den Hypothesen gemäss kann bestätigt werden, dass ein bedeutender Zusammenhang zwischen der Einstellung zu einer Tätigkeit bzw. der Motivation und dem psychischen Wohlbefinden besteht. Die negativen Auswirkungen von tiefer Motivation können durch eine hohe allgemeine Selbstwirksamkeitserwartung etwas abgefedert werden. Allerdings hat sich erwiesen, dass die allgemeine Selbstwirksamkeitserwartung selber gewissen kontextbezogenen Einflussfaktoren unterliegt. Bemerkenswert ist zudem, dass einzig die spezifische Ergebniserwartung, also die Erwartung, die Rekrutenschule erfolgreich abzuschliessen, bezüglich der Voraussage der Aufgabenerfüllung einen nennenswerten Beitrag leistet. Als Erklärung dieses Effekts liegen Mechanismen einer selbsterfüllenden Prophezeiung nahe.

description: We study the interactions of a Bragg-grating soliton with a localized attractive defect which is a combined perturbation of the grating and refractive index. A family of exact analytical solutions for solitons trapped by the delta-like defect is found. Direct simulations demonstrate that, up to the numerical accuracy available, the trapped soliton is stable at a single value of its intrinsic parameter ("mass"). Trapped solitons with larger mass relax to the stable one through the emission of radiation, while the solitons with smaller mass decay. Depending on values of parameters, simulations of collisions between moving solitons and the defect show that the soliton can get captured, pass through, or even bounce from the defect. If the defect is strong and the soliton is heavy enough, it may split, as a result of the collision, into three fragments: trapped, transmitted, and reflected ones.

Interwoven Lovers: Safavid Narrative Silks Depicting Characters from the Khamsa

description: In the twelfth century, Persian language poet Niẓāmī Ganjavī (1141-1209) authored a quintet of epic poems on five subjects, known as the Khamsa or “Five Treasures.” Two of Nizami’s works in the collection are romances based on legendary figures whose tales were grounded in historical events: the love story of Sasanian king Khusrau Parvīz and Armenian princess Shīrīn, and that of Bedouin beauty Laylā and her admirer Qays, aka “Majnūn” [Ar. “madman”]. In the centuries following Nizami’s codification of the characters, several illustrated manuscripts of the Khamsa were produced by workshops for the ruling classes throughout greater Iran, some by later poets who composed their own Khamsa manuscripts. By the turn of the sixteenth century, scenes representing a few pivotal events in the respective narratives had become part of the cycle of illustration, and well known among the educated elite. Between 1550 and 1650, silk luxury textiles depicting these scenes were produced, possibly representing royal as well as independent textile workshop manufacture. A group of eleven different signed and unsigned textile designs depicting scenes from Khusrau and Shīrīn and Laylā and Majnūn are the basis of this study. The textiles will be examined alongside contemporary Khamsa manuscript illustrations, evaluated as a group and individually, and analyzed for their iconological properties based on patronage and consumerism.

description: There exist methods to reformulate in an exact way the many-body problem of interacting bosons in terms of the stochastic evolution of single particle wave functions. For one such reformulation, the so-called simple Fock scheme, we present an elementary derivation, much simpler than the original one. Furthermore, we show that two other schemes, based on coherent states of the matter field rather than on Fock states, lead to an infinite statistical uncertainty in the continuous time limit. The simple Fock scheme is therefore, up to now, the only one that was proved to lead to a convergent Monte Carlo simulation scheme at all times.

description: Detections of gravitational waves (GWs) may soon uncover the signal from the coalescence of a black hole - neutron star (BHNS) binary, that is expected to be accompanied by an electromagnetic (EM) signal. In this paper, we present a composite semi-analytical model to predict the properties of the expected EM counterpart from BHNS mergers, focusing on the kilonova emission and on the gamma-ray burst afterglow. Four main parameters rule the properties of the EM emission: the NS mass $M_\mathrm{NS}$, its tidal deformability $Λ_\mathrm{NS}$, the BH mass and spin. Only for certain combinations of these parameters an EM counterpart is produced. Here we explore the parameter space, and construct light curves, analysing the dependence of the EM emission on the NS mass and tidal deformability. Exploring the NS parameter space limiting to $M_\mathrm{NS}-Λ_\mathrm{NS}$ pairs described by a physically motivated equations of state (EoS), we find that the brightest EM counterparts are produced in binaries with low mass NSs (fixing the BH properties and the EoS). Using constraints on the NS EoS from GW170817, our modeling shows that the emission falls in a narrow range of absolute magnitudes. Within the range of explored parameters, light curves and peak times are not dissimilar to those from NSNS mergers, except in the B band. The lack of an hyper/supra-massive NS in BHNS coalescences causes a dimming of the blue kilonova emission in absence of the neutrino interaction with the ejecta.

description: We reexamine the oscillator construction of the D25-brane solution and the tachyon fluctuation mode of vacuum string field theory given previously. Both the classical solution and the tachyon mode are found to violate infinitesimally their determining equations in the level cut-off regularization. We study the effects of these violations on physical quantities such as the tachyon mass and the ratio of the energy density of the solution relative to the D25-brane tension. We discuss a possible way to resolve the problem of reproducing the expected value of one for the ratio.

description: Die Arbeiterbewegung hat sich ursprünglich der sozioökonomischen Schattenseite der Industrialisierung verschrieben. Für die ökologischen Nebenfolgen der technoökonomischen Entwicklung haben die linken Gesellschaftskritiker insofern kein Gespür gezeigt, als der historische Naturschutz bis in die 1970er Jahre eine traditionelle Domäne der Konservativen war. Die Linke verstand sich selbst als „progressiv“ und glaubte, einzig mit dem Fortschreiten von Wachstum und Technologie die Utopie einer sozialistischen Zukunft realisieren zu können. Dann aber – im Zuge der ökologischen Zäsur Ende der 1960er Jahre – wurde das Verhältnis zur Natur aus einer neuen Perspektive betrachtet. Die sich für die Umwelt zuständig fühlenden Kräfte gruppierten sich um. Das Umweltthema geriet in das Blickfeld der Arbeiterparteien, die sich mit dem eigenen Fortschrittsmythos auseinander zu setzen hatten. Wie haben die „Progressiven“ die Diskussion um die Grenzen der wirtschaftlichen und technologischen Entwicklung geführt? Welche traditionellen Denkmuster wurden im Zuge der Lernprozesse ökologisch aufgebrochen? Welchen Einfluss hatte der Umweltdiskurs der Linken auf das gesamtgesellschaftliche Reden und Denken über die Umwelt?
Rivalry of diffusion, external field and gravity in micro-convection of magnetic colloids

description: Magnetic fields and magnetic materials have promising microfluidic applications. For example, magnetic micro-convection can enhance mixing considerably. However, previous studies have not explained increased effective diffusion during this phenomenon. Here we show that enhanced interface smearing comes from a gravity induced convective motion within a thin microfluidic channel, caused by a small density difference between miscible magnetic and non-magnetic fluids. This motion resembles diffusive behavior and can be described with an effective diffusion coefficient. We explain this with a theoretical model, based on a dimensionless gravitational Rayleigh number, and verify it by numerical simulations and experiments with different cell thicknesses. Results indicate the applicability and limitations for microfluidic applications of other colloidal systems. Residual magnetic micro-convection follows earlier predictions.

description: Programming is a fascinating activity that can yield results capable of changing people lives by automating daily tasks or even completely reimagining how we perform certain activities. Such a great power comes with a handful of challenges, with software maintainability being one of them. Maintainability cannot be validated by executing the program but has to be assessed by analyzing the codebase. This tedious task can be also automated by the means of software development. Programs called static analyzers can process source code and try to detect suspicious patterns. While these programs were proven to be useful, there is also an evidence that they are not used in practice. In this dissertation we discuss the concept of quality-aware tooling —- an approach that seeks a promotion of static analysis by seamlessly integrating it into development tools. We describe our experience of applying quality-aware tooling on a core distribution of a development environment. Our main focus is to provide live quality feedback in the code editor, but we also integrate static analysis into other tools based on our code quality model. We analyzed the attitude of the developers towards the integrated static analysis and assessed the impact of the integration on the development ecosystem. As a result 90% of software developers find the live feedback useful, quality rules received an overhaul to better match the contemporary development practices, and some developers even experimented with a custom analysis implementations. We discovered that live feedback helped developers to avoid dangerous mistakes, saved time, and taught valuable concepts. But most importantly we changed the developers' attitude towards static analysis from viewing it as just another tool to seeing it as an integral part of their toolset.

description: Extremal black holes have vanishing Hawking temperatures. In this article, we argue that for asymptotically AdS black holes, at extremality, a particular class of correlators in the dual CFT can exhibit exponential, maximally chaotic growth with a non-vanishing temperature. Our approach, at extremality, is two-fold. First, we geometrically investigate the modes that are responsible for chaos. Secondly, we study the dynamics of a probe string to capture chaos in worldsheet correlators. For rotating BTZ at extremality, the corresponding Lyapunov exponent is determined by the left-moving temperature. In higher dimensional AdS-Kerr geometries, on the other hand, the corresponding Lyapunov exponent becomes a non-trivial function of the Frolov-Thorne temperatures.

Non-Abelian geometric potentials and spin-orbit coupling for periodically driven systems

description: We demonstrate the emergence of the non-Abelian geometric potentials and thus the three-dimensional (3D) spin-orbit coupling (SOC) for ultracold atoms without using the laser beams. This is achieved by subjecting an atom to a periodic perturbation which is the product of a position-dependent Hermitian operator $\hat{V}\left(\mathbf{r}\right)$ and a fast oscillating periodic function $f\left(ωt\right)$ with a zero average. To have a significant spin-orbit coupling (SOC), we analyze a situation where the characteristic energy of the periodic driving is not necessarily small compared to the driving energy $\hbarω$. Applying a unitary transformation to eliminate the original periodic perturbation, we arrive at a non-Abelian (non-commuting) vector potential term describing the 3D SOC. The general formalism is illustrated by analyzing the motion of an atom in a spatially inhomogeneous magnetic field oscillating in time. A cylindrically symmetric magnetic field provides the SOC involving the coupling between the spin $\mathbf{F}$ and all three components of the orbital angular momentum (OAM) $\mathbf{L}$. In particular, the spherically symmetric monopole-type synthetic magnetic field $\mathbf{B}\propto\mathbf{r}$ generates the 3D SOC of the $\mathbf{L}\cdot \mathbf{F}$ form, which resembles the fine-structure interaction of hydrodgen atom. However, the strength of the SOC here goes as $1/r^{2}$ for larger distances, instead of $1/r^3$ as in atomic fine structure. Such a longer-ranged SOC significantly affects not only the lower states of the trapped atom, but also the higher ones. Furthermore, by properly tailoring the external trapping potential, the ground state of the system can occur at finite OAM, while the ground state of hydrogen atom has zero OAM.

description: In Parallel with the latest scientific mutations and Technological developments, many contemporary artistic trends have emerged under the influence of the contemporary phase of the historical relationship between art, sciences, and technology. This relationship became able to change the methodology of the artistic creation processes totally to the extent that it represents separate artistic movements every one of them can actively refer to a new scientific approach to reinterpreting our understanding of the arts in our contemporary cultures. One of the most significant artistic movements emerged since the middle of the 1960s until now is Laser-Art, in which light can reach its maximum values as a Hypermaterial that can independently constitute the artwork technically and conceptually simultaneously. This thesis contextualizes laser art as an independent artistic trend has its history, classifications, criteria, philosophy, and aesthetical aspects. Via several analytical studies theoretically and practically, the thesis proves that laser art actively contributes, as an independent artistic trend, to change the conceptual definition of the artistic material. On the other hand, bridge the gap between the artistic context and the technical issues, in which the conceptual values became fully integrated into the physical properties of the medium (laser beam), therefore it became impossible to separate the idea and the material of the artwork from each other. Besides, the thesis reveals the potential hidden conceptual and philosophical dimensions of the holographic art as one of the most important branches of laser art. In advanced step, the research suggested a new model of interactive holographic art based on neural controlling, and how this advanced approach can lead us towards a new kind of the aesthetic values, in which participants effectively contribute neurologically to constituting the artwork itself.

description: We present an approach to the parametrized post-Newtonian (PPN) formalism which is based on gauge-invariant higher order perturbation theory. This approach divides the components of the metric perturbations into gauge-invariant quantities, which carry information about the physical system under consideration, and pure gauge quantities, which describe the choice of the coordinate system. This separation generally leads to a simplification of the PPN procedure, since only the gauge-invariant quantities appear in the field equations and must be determined by solving them. Another simplification arises from the fact that the gauge-invariant approach supersedes the necessity to first choose a gauge for solving the gravitational field equations and later transforming the obtained solution into the standard PPN gauge, as it is conventionally done in the PPN formalism, whose standard PPN gauge is determined only after the full solution is known. In addition to the usual metric formulation, we also present a tetrad formulation of the gauge-invariant PPN formalism. To illustrate their practical application, we demonstrate the calculation of the PPN parameters of a well-known scalar-tensor class of theories.

Empirically-Grounded Construction of Bug Prediction and Detection Tools

description: There is an increasing demand on high-quality software as software bugs have an economic impact not only on software projects, but also on national economies in general. Software quality is achieved via the main quality assurance activities of testing and code reviewing. However, these activities are expensive, thus they need to be carried out efficiently. Auxiliary software quality tools such as bug detection and bug prediction tools help developers focus their testing and reviewing activities on the parts of software that more likely contain bugs. However, these tools are far from adoption as mainstream development tools. Previous research points to their inability to adapt to the peculiarities of projects and their high rate of false positives as the main obstacles of their adoption. We propose empirically-grounded analysis to improve the adaptability and efficiency of bug detection and prediction tools. For a bug detector to be efficient, it needs to detect bugs that are conspicuous, frequent, and specific to a software project. We empirically show that the null-related bugs fulfill these criteria and are worth building detectors for. We analyze the null dereferencing problem and find that its root cause lies in methods that return null. We propose an empirical solution to this problem that depends on the wisdom of the crowd. For each API method, we extract the nullability measure that expresses how often the return value of this method is checked against null in the ecosystem of the API. We use nullability to annotate API methods with nullness annotation and warn developers about missing and excessive null checks. For a bug predictor to be efficient, it needs to be optimized as both a machine learning model and a software quality tool. We empirically show how feature selection and hyperparameter optimizations improve prediction accuracy. Then we optimize bug prediction to locate the maximum number of bugs in the minimum amount of code by finding the most cost-effective combination of bug prediction configurations, i.e., dependent variables, machine learning model, and response variable. We show that using both source code and change metrics as dependent variables, applying feature selection on them, then using an optimized Random Forest to predict the number of bugs results in the most cost-effective bug predictor. Throughout this thesis, we show how empirically-grounded analysis helps us achieve efficient bug prediction and detection tools and adapt them to the characteristics of each software project.

description: Without effective developing country participation in climate mitigation it will be impossible to meet global concentration and climate change targets. However, developing countries are unwilling and, in many cases, unable to bear the mitigation cost alone. They need huge transfers of resources – financial, knowledge, technology, and capability – from industrialised countries. In this paper, we evaluate instruments that can induce such resource transfers, including tradable credits, mitigation funds and results-based agreements. We identify key constraints that affect the efficiency and political potential of different instruments, including two-sided private information leading to adverse selection, moral hazard and challenging negotiations; incomplete contracts leading to under-investment; and high levels of uncertainty about emissions paths and mitigation potential. We consider evidence on the poor performance of current approaches to funding developing country mitigation – primarily purchasing offsets through the Clean Development Mechanism – and explore to what extent other approaches can address problems with offsets. We emphasise the wide spectrum of situations in developing countries and suggest that solutions also need to be differentiated and that no one policy will suffice: some policies will be complements, while others are substitutes. We conclude by identifying research needs and proposing a straw man to broaden the range of “contracting” options considered.

description: We explore holographic entanglement entropy for Minkowski spacetime in three and four dimensions. Under some general assumptions on the putative holographic dual, the entanglement entropy associated to a special class of subregions can be computed using an analog of the Ryu-Takayanagi formula. We refine the existing prescription in three dimensions and propose a generalization to four dimensions. Under reasonable assumptions on the holographic stress tensor, we show that the first law of entanglement is equivalent to the gravitational equations of motion in the bulk, linearized around Minkowski spacetime.

description: For this work, we introduced the use of binary amplitude for our proposed complex amplitude encoding of a phase-only hologram. By principle, a complex amplitude in a hologram plane can be represented by the amplitude and its phase. However, a phase-only hologram contains only phase information of the complex amplitude, which results in degradation of reconstruction quality from the hologram. In our method, by approximating the amplitude in the hologram plane using a binary amplitude, we can finally record the complex amplitude of an original light in the phase-only hologram. We validated the effectiveness of our method with two examples, hologram reconstruction and generation of Hermite-Gaussian beams.

description: In the immediate aftermath of the approval of the ban on constructing minarets in a national referendum in late 2009 initiated by right wing populist parties to support their anti-immigration politics, the Swiss Muslim debate took an ironic turn, as a number of Swiss converts to Islam entered public arenas in an ostentative salafi guise, triggering heated debates on the “integratedness” of Switzerland’s Muslim “minority. Dominating news coverage on Muslims and Islam in Switzerland in the first half of 2010, the Swiss converts heading the newly founded Muslim organization, the Islamischer Zentralrat Schweiz, were to replace the minarets as nodal points of problematizing a perceived lack of common symbolic ground between Swiss society and the Muslim migrant population. This thesis places the symbolic stakes of Swiss converts to Islam in both public and Muslim arenas into the centre of its analytical focus in order to reconstruct the Swiss Muslim debate and the shaping of Muslim selves as interrelated processes by the analysis of media coverage on the IZRS and ethnographic data gained in Muslim fields between 2008 and 2011. To do this, the symbolic stakes of Swiss converts to Islam of either gender are reconstructed before the epistemic background of what is often rhetorically invoked as a „crisis of multiculturalism“ (see for example Grillo 2003; Turner 2006; Lentin and Titley 2001; Van Reedom, Dyuvenadak and Bertossi 2012; Vertovec 2011) fuelled by a global „hyperdiscourse“ on Islam that has undergirded public debates on immigration, integration, nationalism and secularism in Swiss public debates just as in other national European contexts. The analytical focus chosen brings together a range of research perspectives and conceptual outlooks. Differing from existing research on European converts to Islam that focusses on questions developed in the field of religious sociology or phenomenological sociology, this study adopts a performative approach on conversion to Islam as a paradigmatic form of subjectivation in line with a Foucauldian discourse analytical perspective. To do this, it develops a deconstructive reading on subjectivation that draws on approaches developed in the field (post)structuralism, psycholanalysis and gender studies which it combines with narratological perspectives on religious conversion as a theme and dramaturgy.

Quantum Dots with Disorder and Interactions: A Solvable Large-g Limit

description: We show that problem of interacting electrons in a quantum dot with chaotic boundary conditions is solvable in the large-g limit, where g is the dimensionless conductance of the dot. The critical point of the $g=\infty$ theory (whose location and exponent are known exactly) that separates strong and weak-coupling phases also controls a wider fan-shaped region in the coupling-1/g plane, just as a quantum critical point controls the fan in at T>0. The weak-coupling phase is governed by the Universal Hamiltonian and the strong-coupling phase is a disordered version of the Pomeranchuk transition in a clean Fermi liquid. Predictions are made in the various regimes for the Coulomb Blockade peak spacing distributions and Fock-space delocalization (reflected in the quasiparticle width and ground state wavefunction).

 Discussion: This is a very small species (body size 3–4 mm) as noted by Spieth (1943), in the species description. It is known from Surinam, Brazil and Venezuela. Peters & Dominguez (2001) detailed variations in size, and coloration. The Venezuelan specimens are larger and the color pattern is more pronounced than the others. H. minuta can be separated from the other species of the genus by the following combination of characters. Imago: 1) general coloration reddish brown, heavily washed with blackish brown; 2) upper portion of male eyes separated basally, meeting medially with well developed eye bridge on inner margin of upper portion; 3) first forceps segment around 2 times length of styliger plate, and curved medially; 4) hind femora yellowish, with wide subbasal and apical dark bands; 5) cerci pale, articulations of basal 3 segments darker.

description: Hadronization corrections to the thrust and related event shape distributions in the two-jet kinematical region of e+e- annihilation are summarized by nonperturbative shape functions. The moments of shape functions are given by universal matrix elements in QCD, which describe the energy flow in QCD final states. We show how the nonperturbative structure of these matrix elements may be inferred from resummed perturbation theory and Lorentz invariance. This analysis suggests the same functional forms for the shape functions as were found in phenomenological studies, and sheds light on the physical significance of the parameters that characterize these functions.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Private land-use decisions are critical for a broad spectrum of environmental and social outcomes, ranging from water quality and climate change to rural income distribution. I use a large dataset of the land-use decisions of New Zealand landowners to estimate a cross-sectional multinomial logit model of land use. In this model, the optimal land-use choice depends on geophysical attributes of the land, the cost of access to markets, and on land tenure (Māori freehold title versus general freehold title). I employ the estimated relationship in a counterfactual scenario to assess the overall impact of Māori tenure on the willingness of landowners to supply land for the four most important rural uses in the country: dairying; sheep or beef farming; plantation forestry; and an economically unproductive use, scrub. This allows me to conjecture about the environmental implications of New Zealand’s land-tenure system.

description: We discuss several methods which can be used to distinguish the graviton resonances of the Randall-Sundrum model from the graviton-like resonances which may occur in other theories. The Breit-Wigner line shape of the RS graviton is found to be particularly useful. In particular we show that the "effective" graviton resonance present in the model of Dvali et al ~can be distinguished from those of the Randall-Sundrum scenario for a reasonably wide range of model parameters.
