description: Diese Masterthese versucht darzustellen, welche Auswirkungen die Erweiterung der Flugplatzgrenzen auf die unmittelbar benachbarten Grundstückseigentümer besonders für das im Westen angrenzende Schotterwerk hat und ob der Flughafen Graz den Erwerb der nunmehr als Flugplatz gewidmeten Grundstücke durch eine behördliche Enteignung durchsetzen kann. Im Ergebnis ist zu beantworten, dass solange die FBG nicht im Stande ist, den Nachweis der Notwendigkeit zur Einbeziehung der betreffenden Liegenschaften für ein konkretes im öffentlichen Interesse liegendes Vorhaben tatsächlich zu erbringen, sind die Voraussetzungen für ein Enteignungsverfahren nach dem LFG nicht gegebenen. Für den Fall, dass die FBG den Nachweis der Notwendigkeit erbringen kann, und die Enteignung der Alois Schönberger GmbH zugehörigen Liegenschaften somit zulässig ist, hat der Enteignete im Rahmen der gerichtlichen Entschädigungsfestsetzung keinerlei vermögensrechtliche Nachteile zu erwarten. Das Enteignungsrecht geht von der Ersatzbeschaffung aus, sodass der durch den Eingriff belastete Grundeigentümer mit der Leistung einer Ausgleichszahlung wieder in jene Vermögenslage versetzt wird, in der er sich vor diesem Eingriff befunden hat. Zusammenfassend ist sohin festzustellen, dass der Zweck der Entschädigung darin besteht, den enteignungsbedingten Vermögensnachteil wieder auszugleichen. Dabei ist die Entschädigung nicht auf den Ersatz des Substanzverlustes beschränkt, sondern es sind auch alle übrigen Vermögensnachteile zu ersetzen. Im Ergebnis setzt sich eine Enteignungsentschädigung aus folgenden drei Bestandteilen zusammen: 1. Ersatz des im Verkehrswertes enthaltenen Substanzverlustes des Grundstückes; 2. Ersatzbeschaffungsspesen in der anerkannten Höhe von 7,5%, sowie 3. Ersatz aller übrigen Vermögensfolgeschäden. Nicht dem Wert des Enteignungsgegenstandes kommt daher besondere Bedeutung zu, sondern der Verfügbarkeit zur Beschaffung eines gleichartigen und gleichwertigen Ersatzgrundstückes mit einer vergleichenden Widmung.

description: Early observations of Type Ia supernovae (SNe$\,$Ia) provide essential clues for understanding the progenitor system that gave rise to the terminal thermonuclear explosion. We present exquisite observations of SN$\,$2019yvq, the second observed SN$\,$Ia, after iPTF$\,$14atg, to display an early flash of emission in the ultraviolet (UV) and optical. Our analysis finds that SN$\,$2019yvq was unusual, even when ignoring the initial flash, in that it was moderately underluminous for an SN$\,$Ia ($M_g \approx -18.5\,$mag at peak) yet featured very high absorption velocities ($v \approx 15,000\,\mathrm{km\,s}^{-1}$ for Si II $λ$6355 at peak). We find that many of the observational features of SN$\,$2019yvq, aside from the flash, can be explained if the explosive yield of radioactive $^{56}\mathrm{Ni}$ is relatively low (we measure $M_{^{56}\mathrm{Ni}} = 0.31 \pm 0.05\,M_\odot$) and it and other iron-group elements are concentrated in the innermost layers of the ejecta. To explain both the UV/optical flash and peak properties of SN$\,$2019yvq we consider four different models: interaction between the SN ejecta and a nondegenerate companion, extended clumps of $^{56}\mathrm{Ni}$ in the outer ejecta, a double-detonation explosion, and the violent merger of two white dwarfs. Each of these models has shortcomings when compared to the observations; it is clear additional tuning is required to better match SN$\,$2019yvq. In closing, we predict that the nebular spectra of SN$\,$2019yvq will feature either H or He emission, if the ejecta collided with a companion, strong [Ca II] emission, if it was a double detonation, or narrow [O I] emission, if it was due to a violent merger.

description: Meta-analysis aims to generalize results from multiple related statistical analyses through a combined analysis. While the natural outcome of a Bayesian study is a posterior distribution, traditional Bayesian meta-analyses proceed by combining summary statistics (i.e., point-valued estimates) computed from data. In this paper, we develop a framework for combining posterior distributions from multiple related Bayesian studies into a meta-analysis. Importantly, the method is capable of reusing pre-computed posteriors from computationally costly analyses, without needing the implementation details from each study. Besides providing a consensus across studies, the method enables updating the local posteriors post-hoc and therefore refining them by sharing statistical strength between the studies, without rerunning the original analyses. We illustrate the wide applicability of the framework by combining results from likelihood-free Bayesian analyses, which would be difficult to carry out using standard methodology.

description: We determined the lattice dynamics of metastable, surface-stabilized $α$-phase FeSi$_2$ nanoislands epitaxially grown on the Si(111) surface with average heights and widths ranging from 1.5 to 20 nm and 18 to 72 nm, respectively. The crystallographic orientation, surface morphology and local crystal structure of the nanoislands were investigated by reflection high-energy electron diffraction, atomic force microscopy and X-ray absorption spectroscopy. The Fe-partial phonon density of states (PDOS), obtained by nuclear inelastic scattering, exhibits a pronounced damping and broadening of the spectral features with decreasing average island height. First-principles calculations of the polarization-projected Si- and Fe-partial phonon dispersions and PDOS enable the disentanglement of the contribution of the $xy$- and $z$-polarized phonons to the experimental PDOS. Modeling of the experimental data with the theoretical results unveils an enhanced damping of the $z$-polarized phonons for islands with average sizes below 10 nm. This phenomenon is attributed to the fact that the low-energy $z$-polarized phonons couple to the low-energy surface/interface vibrational modes. The thermodynamic and elastic properties obtained from the experimental data show a pronounced size-dependent behavior.

description: BAKGRUNN
Økende bruk av medisinske implantater i mange fagdisipliner fører til flere eksplantater. Med fjerning av implantater oppstår spørsmålet om den videre håndteringen av produktet.
Hvem eier eksplantater, og hvordan håndtere eksplantater som pasienten krever utlevert eller som forblir i klinikken? Hvordan, hvor, av hvem og under hvilke forhold foregår rengjøring, desinfisering og emballasje av dette tidligere implantatet og nåværende eksplantat?
I denne analyse av rettskilder å gi svar på juridiske spørsmålene som kan oppstå ved håndtering av eksplantater
RESULTATER
Pasienten eier eksplantatet. Eksplantater er ikke lenger medisinsk utstyr. Prosedyren for dekontaminering av eksplantater er ikke enhetlig regulert. Virksomheten er ansvarlig. Uklar risikosituasjon for bruk av vaskedekontaminator og annet utstyr.
FASIT
Reprosessering av eksplantater bør reguleres i en egen retningslinje. Rengjøring, desinfisering, emballering av eksplanter bør gjøres i spesiallagde og egnede rom med eget utstyr. Kompetansen av ledere i sterilforsyningsenheter bør tas i bruk.

description: We compute the two-dimensional correlation functions of the binary black hole coalescence detections in LIGO-Virgo's first and second observation runs. The sky distribution of binary black hole coalescence events is tested for correlations at different angular scales by comparing the observed correlation function to two reference functions that are obtained from mock datasets of localization error regions uniformly distributed in the sky. No excess correlation at any angular scale is found. The power-law slope of the correlation function is estimated to be $γ= 2.24\pm 0.33$ at the three-$σ$ confidence level, a value consistent with the measured distribution of galaxies.

description: We report the detection of the linear radical HC4N in the C-rich envelope of IRC+10216. After HCCN, HC4N is the second member of the allenic chain family HC_(2n)N observed in space. The column density of HC4N is found to be 1.5 10**12 cm**(-2). The abundance ratio HC2N/HC4N is 9, a factor of two larger than the decrement observed for the cyanopolyynes HC$_(2n+1)N/HC_(2n+3)N. Linear HC_4N has a 3-Sigma electronic ground state and is one of the 3 low-energy isomeric forms of this molecule. We have searched for the bent and ringed HC4N isomers, but could only derive an upper limit to their column densities of about 3 10**(12) cm**(-2).

description: Knowledge of molecular structure is paramount in understanding, and ultimately influencing, chemical reactivity. For nearly a century, diffractive imaging has been used to identify the structures of many biologically-relevant gas-phase molecules with atomic (i.e. Angstrom, A; 1 A = 10$^{-10}$ m) spatial resolution. Unravelling the mechanisms of chemical reactions requires the capability to record multiple well-resolved snapshots of the molecular structure as it is evolving on the nuclear (i.e. femtosecond, fs; 1 fs = 10$^{-15}$ s) timescale. We present the latest, state-of-the-art ultrafast electron diffraction methods used to retrieve the molecular structure of gas-phase molecules with Angstrom and femtosecond spatio-temporal resolution. We first provide a historical and theoretical background to elastic electron scattering in its application to structural retrieval, followed by details of field-free and field-dressed ultrafast electron diffraction techniques. We discuss the application of these ultrafast methods to time-resolving chemical reactions in real-time, before providing a future outlook of the field and the challenges that exist today and in the future.

description: We study a model of spontaneous wavefunction collapse for a free quantum particle. We analyze in detail the time evolution of the single-Gaussian solution and the double-Gaussian solution, showing how the reduction mechanism induces the localization of the wavefunction in space; we also study the asymptotic behavior of the general solution. With an appropriate choice for the parameter $λ$ which sets the strength of the collapse mechanism, we prove that: i) the effects of the reducing terms on the dynamics of microscopic systems are negligible, the physical predictions of the model being very close to those of standard quantum mechanics; ii) at the macroscopic scale, the model reproduces classical mechanics: the wavefunction of the center of mass of a macro-object behaves, with high accuracy, like a point moving in space according to Newton's laws.

description: Let $M$ be a random matrix chosen according to Haar measure from the unitary group $\mathrm{U}(n,\mathbb{C})$. Diaconis and Shahshahani proved that the traces of $M,M^2,\ldots,M^k$ converge in distribution to independent normal variables as $n \to \infty$, and Johansson proved that the rate of convergence is superexponential in $n$.
 We prove a finite field analogue of these results. Fixing a prime power $q = p^r$, we choose a matrix $M$ uniformly from the finite unitary group $\mathrm{U}(n,q)\subseteq \mathrm{GL}(n,q^2)$ and show that the traces of $\{ M^i \}_{1 \le i \le k,\, p \nmid i}$ converge to independent uniform variables in $\mathbb{F}_{q^2}$ as $n \to \infty$. Moreover we show the rate of convergence is exponential in $n^2$. We also consider the closely related problem of the rate at which characteristic polynomial of $M$ equidistributes in `short intervals' of $\mathbb{F}_{q^2}[T]$. Analogous results are also proved for the general linear, special linear, symplectic and orthogonal groups over a finite field. In the two latter families we restrict to odd characteristic.
 The proofs depend upon applying techniques from analytic number theory over function fields to formulas due to Fulman and others for the probability that the characteristic polynomial of a random matrix equals a given polynomial.

description: A magnetic Bragg reflection corresponding to the wave vector k13 = (2pi/a)[1/2,1/2,1/2] of the antiferro-quadrupolar ordering is found in CeB6 in zero magnetic field below the Neel temperature TN. Its intensity is two orders of magnitude weaker than those due to the basic magnetic structure [O. Zaharko et al., Phys. Rev. B 68, 214401 (2003)]. The peak has a width of the other Bragg reflections below TN, but widens abruptly at T = TN with simultaneous increase of intensity. Correlation length just above TN is of the order of 70 A. The peak intensity decreases to zero at T = 7 K with no visible anomaly at the antiferro-quadrupolar ordering temperature TQ = 3.3 K. The features of this magnetic ordering are typical for the itinerant magnetism with 5d electron of Ce3+ [Yu.S. Grushko et al., phys. stat. sol. (b) 128, 591 (1985)] being involved.

description: We study the circumradius of the intersection of an $m$-dimensional ellipsoid $\mathcal E$ with semi-axes $σ_1\geq\dots\geq σ_m$ with random subspaces of codimension $n$. We find that, under certain assumptions on $σ$, this random radius $\mathcal{R}_n=\mathcal{R}_n(σ)$ is of the same order as the minimal such radius $σ_{n+1}$ with high probability. In other situations $\mathcal{R}_n$ is close to the maximum $σ_1$. The random variable $\mathcal{R}_n$ naturally corresponds to the worst-case error of the best algorithm based on random information for $L_2$-approximation of functions from a compactly embedded Hilbert space $H$ with unit ball $\mathcal E$. In particular, $σ_k$ is the $k$th largest singular value of the embedding $H\hookrightarrow L_2$. In this formulation, one can also consider the case $m=\infty$, and we prove that random information behaves very differently depending on whether $σ\in \ell_2$ or not. For $σ\notin \ell_2$ random information is completely useless, i.e., $\mathbb E[\mathcal{R}_n] = σ_1$. For $σ\in \ell_2$ the expected radius of random information tends to zero at least at rate $o(1/\sqrt{n})$ as $n\to\infty$. In the important case $σ_k \asymp k^{-α} \ln^{-β}(k+1)$, where $α> 0$ and $β\in\mathbb R$, we obtain that $$ \mathbb E [\mathcal{R}_n(σ)] \asymp \begin{cases} σ_1 & : α<1/2 \,\text{ or }\, β\leqα=1/2 \\ σ_n \, \sqrt{\ln(n+1)} & : β>α=1/2 \\ σ_{n+1} & : α>1/2. \end{cases} $$ In the proofs we use a comparison result for Gaussian processes à la Gordon, exponential estimates for sums of chi-squared random variables, and estimates for the extreme singular values of (structured) Gaussian random matrices. The upper bound is constructive. It is proven for the worst case error of a least squares estimator.

Seeing trees or seeing forests in simultanagnosia : attentional capture can be local or global
Creators: name: Dalrymple, Kirsten Anne
Publisher: name: University of British Columbia
Year: 2010

description: Patients with simultanagnosia often demonstrate ’local capture’, meaning that they identify only the local elements of stimuli that contain a hierarchy of both local and global structures. Recent studies, however, have found that these patients may implicitly process the global form. We examined the general applicability of the concept of local capture, and specifically whether the global level of stimuli can be explicitly reported by patients with simultanagnosia. We tested a patient with simultanagnosia with globally biased stimuli such as hierarchical Arcimboldo faces and small, dense Navon letters. With Arcimboldo faces our patient often reported only the face and not the local elements -- the first demonstration of global rather than local capture. With Navon letters, the patient’s ability to report the global letter varied with stimulus density and inversely with stimulus size, so that local capture was found only with large and sparse stimuli. With both faces and letters, the likelihood of global capture by the patient was related to the ease of global reporting in controls, as indexed by their reaction times. This suggests that the patient’s global perception is influenced by the same factors operating in healthy individuals. We conclude that attentional capture in simultanagnosia can be either global or local. Capture likely occurs because of a pathological restriction and/or rigidity of attention, but the type of capture depends upon the competitive balance between global and local salience.

description: The divisor sequence of an irreducible element (\textit{atom}) $a$ of a reduced monoid $H$ is the sequence $(s_n)_{n\in \mathbb{N}}$ where, for each positive integer $n$, $s_n$ denotes the number of distinct irreducible divisors of $a^n$. In this work we investigate which sequences of positive integers can be realized as divisor sequences of irreducible elements in Krull monoids. In particular, this gives a means for studying non-unique direct-sum decompositions of modules over local Noetherian rings for which the Krull-Remak-Schmidt property fails.

description: Near-field optical microscopes with two independent tips for simultaneous excitation and detection can be essential tools for studying localized optical phenomena on the subwavelength scale. Here, we report on the implementation of a fully automated and robust dual-tip scanning near-field optical microscope (SNOM), in which the excitation tip is stationary, while the detection tip automatically scans the surrounding area. To monitor and control the distance between the two probes, mechanical interactions due to shear forces are used. We experimentally investigate suitable scan parameters and find that the automated dual-tip SNOM can operate stably for a wide range of parameters. To demonstrate the potential of the automated dual-tip SNOM, we characterize the propagation of surface plasmon polaritons on a gold film for visible and near-infrared wavelengths. The good agreement of the measurements with numerical simulations verifies the capability of the dual-tip SNOM for the near-field characterization of localized optical phenomena.

description: We study the earthquake model by Olami, Feder and Christensen in one dimension. While the size distribution of earthquakes resembles a power law for small system sizes, it splits for larger system sizes into two parts, one comprising small avalanches and showing a size independent cutoff, and the other comprising avalanches of the order of the system size. We identify four different types of attractors of the dynamics of the system which already exist for very small systems. For larger system sizes, these attractors contain large synchronized regions.

description: A microscopic method for calculating nuclear level densities (NLD) is developed, based on the framework of energy density functionals. Intrinsic level densities are computed from single-quasiparticle spectra obtained in a finite-temperature self-consistent mean-field (SCMF) calculation that takes into account nuclear deformation, and is specified by the choice of the energy density functional (EDF) and pairing interaction. The total level density is calculated by convoluting the intrinsic density with the corresponding collective level density, determined by the eigenstates of a five-dimensional quadrupole or quadrupole plus octupole collective Hamiltonian. The parameters of the Hamiltonian (inertia parameters, collective potential) are consistently determined by deformation-constrained SCMF calculations using the same EDF and pairing interaction. The model is applied in the calculation of NLD of $^{94,96,98}$Mo, $^{106,108}$Pd, $^{106,112}$Cd, $^{160,162,164}$Dy, $^{166}$Er, and $^{170,172}$Yb, in comparison with available data. It is shown that the collective enhancement of the intrinsic level density, consistently computed from the eigenstates of the corresponding collective Hamiltonian, leads to total NLDs that are in excellent agreement with data over the whole energy range of measured values.

Relative Maximum Likelihood Updating of Ambiguous Beliefs

subject: FOS: Economics and business

description: This paper proposes and axiomatizes a new updating rule: Relative Maximum Likelihood (RML) for ambiguous beliefs represented by a set of priors (C). This rule takes the form of applying Bayes' rule to a subset of C. This subset is a linear contraction of C towards its subset ascribing a maximal probability to the observed event. The degree of contraction captures the extent of willingness to discard priors based on likelihood when updating. Two well-known updating rules of multiple priors, Full Bayesian (FB) and Maximum Likelihood (ML), are included as special cases of RML. An axiomatic characterization of conditional preferences generated by RML updating is provided when the preferences admit Maxmin Expected Utility representations. The axiomatization relies on weakening the axioms characterizing FB and ML. The axiom characterizing ML is identified for the first time in this paper, addressing a long-standing open question in the literature.

description: New ways of optimizing large software engineering processes are investigated in this thesis, based on the findings out of the two international standardized frameworks CMMI and SPICE. The goal was to find new approaches, inspired by those two standards. Two approaches - the modular approach and the workflow-step classification - were introduced and analyzed in this thesis. The first approach - the modular approach - is based on the idea to keep the workflows inside the processes as dynamic as possible by creating modules which can be used in various ways to fulfill the unique need for the implementation of a certain requirement. The second approach - the workflow-step classification - describes a new way of how to classify and measure workflows inside processes. This approach was created as a measurement strategy for the modular approach, but can also be used in conservative set ups. In the following chapters these two approaches are introduced in detail, leading to an experimental use in an example environment.

description: We investigate the response of two-dimensional pattern forming systems with a broken up-down symmetry, such as chemical reactions, to spatially resonant forcing and propose related experiments. The nonlinear behavior immediately above threshold is analyzed in terms of amplitude equations suggested for a $1:2$ and $1:1$ ratio between the wavelength of the spatial periodic forcing and the wavelength of the pattern of the respective system. Both sets of coupled amplitude equations are derived by a perturbative method from the Lengyel-Epstein model describing a chemical reaction showing Turing patterns, which gives us the opportunity to relate the generic response scenarios to a specific pattern forming system. The nonlinear competition between stripe patterns and distorted hexagons is explored and their range of existence, stability and coexistence is determined. Whereas without modulations hexagonal patterns are always preferred near onset of pattern formation, single mode solutions (stripes) are favored close to threshold for modulation amplitudes beyond some critical value. Hence distorted hexagons only occur in a finite range of the control parameter and their interval of existence shrinks to zero with increasing values of the modulation amplitude. Furthermore depending on the modulation amplitude the transition between stripes and distorted hexagons is either sub- or supercritical.

description: We study the diffraction of atoms and weakly-bound three-atomic molecules from a transmission grating at non-normal incidence. Due to the thickness of the grating bars the slits are partially shadowed. Therefore, the projected slit width decreases more strongly with the angle of incidence than the projected period, increasing, in principle, the experimental resolution. The shadowing, however, requires a revision of the theory of atom diffraction. We derive an expression in the style of the Kirchhoff integral of optics and show that the diffraction pattern exhibits a characteristic asymmetry which must be accounted for when comparing with experimental data. We then analyze the diffraction of weakly bound trimers and show that their finite size manifests itself in a further reduction of the slit width by (3/4) where is the average bond length. The improved resolution at non-normal incidence may in particular allow to discern, by means of their bond lengths, between the small ground state of the helium trimer (=1 nm, Barletta and Kievsky, Phys. Rev. A 64, 042514 (2001)) and its predicted Efimov-type excited state (=8 nm, ibid.), and in this way to experimentally prove the existence of this long-sought Efimov state.

description: In species that care for their young, provisioning has profound effects on offspring fitness. Provisioning is important in honeybees because nutritional cues determine whether a female becomes a reproductive queen or sterile worker. A qualitative difference between the larval diets of queens and workers is thought to drive this divergence; however, no single compound seems to be responsible. Diet quantity may have a role during honeybee caste determination yet has never been formally studied. Our goal was to determine the relative contributions of diet quantity and quality to queen development. Larvae were reared in vitro on nine diets varying in the amount of royal jelly and sugars, which were fed to larvae in eight different quantities. For the middle diet, an ad libitum quantity treatment was included. Once adults eclosed, the queenliness was determined using principal component analysis on seven morphological measurements. We found that larvae fed an ad libitum quantity of diet were indistinguishable from commercially reared queens, and that queenliness was independent of the proportion of protein and carbohydrate in the diet. Neither protein nor carbohydrate content had a significant influence on the first principle component 1 (PC1), which explained 64.4% of the difference between queens and workers. Instead, the total quantity of diet explained a significant amount of the variation in PC1. Large amounts of diet in the final instar were capable of inducing queen traits, contrary to the received wisdom that queen determination can only occur in the third instar. These results indicate that total diet quantity fed to larvae may regulate the difference between queen and worker castes in honeybees.

description: We study the $L_2$-approximation of functions from a Hilbert space and compare the sampling numbers with the approximation numbers. The sampling number $e_n$ is the minimal worst case error that can be achieved with $n$ function values, whereas the approximation number $a_n$ is the minimal worst case error that can be achieved with $n$ pieces of arbitrary linear information (like derivatives or Fourier coefficients). We show that \[
 e_n \,\lesssim\, \sqrt{\frac{1}{k_n} \sum_{j\geq k_n} a_j^2}, \] where $k_n \asymp n/\log(n)$. This proves that the sampling numbers decay with the same polynomial rate as the approximation numbers and therefore that function values are basically as powerful as arbitrary linear information if the approximation numbers are square-summable. Our result applies, in particular, to Sobolev spaces $H^s_{\rm mix}(\mathbb{T}^d)$ with dominating mixed smoothness $s>1/2$ and we obtain \[ e_n \,\lesssim\, n^{-s} \log^{sd}(n). \] For $d>2s+1$, this improves upon all previous bounds and disproves the prevalent conjecture that Smolyak's (sparse grid) algorithm is optimal.

A Kantian solution to the problem of hypochondria
Creators: name: Dennedy, Kyla G.
Publisher: name: University of British Columbia
Year: 2010

description: The thesis explores Kant’s views on the operations of the mind from the perspective of mental infirmity, particularly hypochondria. It argues hypochondria’s public prominence plays a role in the theories of the mind of several philosophers, including Kant. and in turn, Kant’s theory of the operations of the mind helps further the shift to understanding hypochondria as primarily a mental disorder. Kant was a self-proclaimed hypochondriac, and yet was unusual amongst sufferers of the disorder in that he claimed to be able to control his hypochondria by way of regimen and reason. If Kant truly was able to mitigate the deleterious aspects of hypochondria merely by strictly adhering to a regimen which made reason the ruler of the mind, this may have benefit for current sufferers of hypochondria. The thesis argues that Kant hoped his account of the operations of the mind would have empirical consequences for the understanding and amelioration of mental illness in humans. In doing so, it aims to show, contra Strawson and others, that not only are transcendental idealism and the transcendental subject necessary to Kant’s overall philosophy, but removing them, as Strawson does, leaves Kant’s theory unable to account for the empirical . consequences of the faculties of the mind - consequences which are evident when one considers Kant’s own struggle with hypochondria.

description: In a recent paper Rousseau-Rizzi and Emanuel (2019) presented a derivation of an upper limit on maximum hurricane velocity at the surface. This derivation was based on a consideration of an infinitely narrow (differential) Carnot cycle with the warmer isotherm at the point of the maximum wind velocity. Here we show that this derivation neglected a significant term describing the kinetic energy change in the outflow. Additionally, we highlight the importance of a proper accounting for the power needed to lift liquid water. Finally, we provide a revision to the formula for surface fluxes of heat and momentum showing that, if we accept the assumptions adopted by Rousseau-Rizzi and Emanuel (2019), the resulting velocity estimate does not depend on the flux of sensible heat.

description: This paper aims to analyze the economic impact of the legal reserve on the gross margin of different types of farms located in the watershed of the Oriçanga River – in São Paulo state, Brazil. In order to reach such purpose, a typology of farmers was elaborated for the watershed. Two farmer types were selected for a detailed study: small farmers with low technology and citrus producers. The productive structure of both types was modeled through the recursive programming method, comprising the period between 2002/03 and 2008/09. The current farm system adopted by each type was confronted with two scenarios for legal reserve compensation: I) through the reallocation of productive areas within the farms and sustainable management of natural vegetation recovery in order to explore the production of timber; II) through the spontaneous growth of natural vegetation. Results highlight the importance of policies aimed to obtain a more equitable distribution of environmental conservation costs in the society, as well as the importance of locational adjustments of the legal reserves, in order to reach a better equilibrium between the preservation of biodiversity and the opportunity cost of land.

description: We evaluate asymptotically the variance of the number of squarefree integers up to $x$ in short intervals of length $H < x^{6/11 - \varepsilon}$ and the variance of the number of squarefree integers up to $x$ in arithmetic progressions modulo $q$ with $q > x^{5/11 + \varepsilon}$. On the assumption of respectively the Lindelöf Hypothesis and the Generalized Lindelöf Hypothesis we show that these ranges can be improved to respectively $H < x^{2/3 - \varepsilon}$ and $q > x^{1/3 + \varepsilon}$. Furthermore we show that obtaining a bound sharp up to factors of $H^{\varepsilon}$ in the full range $H < x^{1 - \varepsilon}$ is equivalent to the Riemann Hypothesis. These results improve on a result of Hall (1982) for short intervals, and earlier results of Warlimont, Vaughan, Blomer, Nunes and Le Boudec in the case of arithmetic progressions.

description: We use alternative specifications of the Almost Ideal Demand System (AIDS) to estimate the aggregate demand in Brazil for beef, pork, chicken, other consumption goods, and their elasticities. We detect the need for using time trend variables in models’ equations so that we found an upward trend for the demand of each type of meat and a downward trend for other consumption goods. The dummy variable for the prices stabilization macroeconomic Real Plan indicated it has not changed demands. According to Marshallian own-price elasticities, meat demands are inelastic and demand for other consumption goods is elastic. Cross-price Marshallian and Hicksian elasticities confirm beef, pork and chicken are substitutes. Expenditure elasticities show that all goods are normal, except for pork, which is an inferior good. As personal consumption expenditure is likely to increase over time, ceteris paribus, meat consumption will lose importance to other consumption goods, beef consumption will lose importance to chicken and pork consumption will lose importance to the other two types of meat.

description: We consider a quasi-periodically identified conical spacetime, like the one of a cosmic string or disclination, to investigate nonzero averaged quantum vacuum fluctuations effects on the energy-momentum tensor and induced current density associated with a charged scalar field. We obtain exactly closed analytical expressions for the two-point Wightman function and the vacuum expectation value of the field squared, as well as for all components of the energy-momentum tensor. As to the induced current density, due to the quasi-periodic condition used, the only nonzero averaged component found is the azimuthal one. We also compare our results with previous ones found in literature.

description: Employee voice and workplace democracy have a positive impact on employee wellbeing and the performance of organizations. In this paper, we conducted interviews with employees to identify facilitators and inhibitors for the voice within the workplace and a corresponding set of appropriate qualities: Civility, Validity, Safety and Egalitarianism. We then operationalised these qualities as a set of design goals - Assured Anonymity, Constructive Moderation, Adequate Slowness and Controlled Access - in the design and development of a secure anonymous employee voice system. Our novel take on the Enterprise Social Network aims to foster good citizenship whilst also promoting frank yet constructive discussion. We reflect on a two-week deployment of our system, the diverse range of candid discussions that emerged around important workplace issues and the potential for change within the host organization. We conclude by reflecting on the ways in which our approach shaped the discourse and supported the creation of a trusted environment for employee voice.
