description: Complex interactions between high-skilled migration and aggregate performance govern the dynamics of growth and inequality across nations. Due to lack of data, these interdependencies have not been extensively studied in the economics literature. This paper takes advantage of the availability of rich panel data on the mobility of talented football players, and the performances of national leagues and teams to quantify the effect of a "globalization" shock, the 1995 Bosman rule, on global efficiency and cross-country inequality in football. I built a micro-founded model endogenizing migration decisions, inequality and training; I estimated its structural parameters; and I used numerical simulations to compare actual data with a counterfactual no-Bosman trajectory. My analysis reveals that the Bosman shock (i) increased global efficiency in football, (ii) increased inequality across leagues, and (iii) decreased inequality across national teams. I quantify the effect of the Bosman rule on the football hierarchy of UEFA and FIFA. Countries from Africa, South (except Argentina and Brazil) and Central America have produced more talents and benefitted from brain-gain type effects. My results also show that this brain-gain mechanism is the major source of efficiency gains. However, it plays only a minor role in explaining the rising inequality.

description: We report on a comparison between the flux of muons in the atmosphere measured by the CAPRICE98 experiment and simulations performed with the air shower simulation program AIRES. To reduce systematic uncertainties we have used as input the primary fluxes of protons and helium nuclei also measured by the CAPRICE98 experiment. Heavy nuclei are also taken into account in the primary flux, and their contribution to the muon flux is discussed. The results of the simulations show a very good agreement with the experimental data, at all altitudes and for all muon momenta. With the exception of a few isolated points, the relative differences between measured data and simulations are smaller than 20 %; and in all cases compatible with zero within two standard deviations. The influence of the input cosmic ray flux on the results of the simulations is also discussed. This report includes also an extensive analysis of the characteristics of the simulated fluxes.

description: Traditional anyons in two dimensions have generalized exchange statistics governed by the braid group. By analyzing the topology of configuration space, we discover that an alternate generalization of the symmetric group governs particle exchanges when there are hard-core three-body interactions in one-dimension. We call this new exchange symmetry the traid group and demonstrate that it has abelian and non-abelian representations that are neither bosonic nor fermionic, and which also transform differently under particle exchanges than braid group anyons. We show that generalized exchange statistics occur because, like hard-core two-body interactions in two dimensions, hard-core three-body interactions in one dimension create defects with co-dimension two that make configuration space no longer simply-connected. Ultracold atoms in effectively one-dimensional optical traps provide a possible implementation for this alternate manifestation of anyonic physics.

description: We analyze the mixing between $Σ^0$ and $Λ^0$ based on the baryon masses. We distinguish the contributions from QCD and QED in the baryon mass splittings. We find that the mixing angle between $Σ^0$ and $Λ^0$ is $(2.07\pm 0.03)\times 10^{-2} $, which leads to the decay branching fraction and up-down asymmetry of $Λ_c^+ \to Σ^0 e^+ ν_e$ to be ${\cal B}(Λ_c^+ \to Σ^0 e^+ ν_e)=(1.5\pm 0.2)\times 10^{-5}$ and $α(Λ_c^+ \to Σ^0 e^+ ν_e)=-0.86\pm 0.04$, respectively. Moreover, we obtain that $Δ{\cal B}\equiv {\cal B}(Λ_c^+\to Σ^0 π^+) - {\cal B}(Λ_c^+\to Σ^+π^0)=(3.8\pm 0.5)\times 10^{-4}$ and $Δα\equivα(Λ_c^+\to Σ^0 π^+) -α(Λ_c^+\to Σ^+π^0)=(-1.6\pm 0.7)\times10^{-2}$, which should vanish without the mixing.

description: For choice with deterministic consequences, the standard rationality hypothesis is ordinality — i.e., maximization of a weak preference ordering. For choice under risk (resp. uncertainty), preferences are assumed to be represented by the objectively (resp. subjectively) expected value of a von Neumann– Morgenstern utility function. For choice under risk, this implies a key independence axiom; under uncertainty, it implies some version of Savage’s sure thing principle. This chapter investigates the extent to which ordinality, independence, and the sure thing principle can be derived from more fundamental axioms concerning behaviour in decision trees. Following Cubitt (1996), these principles include dynamic consistency, separability, and reduction of sequential choice, which can be derived in turn from one consequentialist hypothesis applied to continuation subtrees as well as entire decision trees. Examples of behavior violating these principles are also reviewed, as are possible explanations of why such violations are often observed in experiments.

description: We calculate the corrections to the Casimir force between two metals due to the spatial dispersion of their response functions. We employ model-independent expressions for the force in terms of the optical coefficients. We express the non-local corrections to the Fresnel coefficients employing the surface $d_\perp$ parameter, which accounts for the distribution of the surface screening charge. Within a self-consistent jellium calculation, spatial dispersion increases the Casimir force significatively for small separations. The nonlocal correction has the opposite sign than previously predicted employing hydrodynamic models and assuming abruptly terminated surfaces.

PURPOSE: Supervisors may be prone to implicit (unintentional) bias when granting procedural autonomy to trainees due to the subjectivity of autonomy decisions. The authors aimed to conduct a systematic review and meta-analysis to assess the differences in perceptions of procedural autonomy granted to physician trainees based on gender and/or race. METHOD: MEDLINE, Embase, CENTRAL, Scopus, and Web of Science were searched (search date: January 5, 2022) for studies reporting quantitative gender- or race-based differences in perceptions of procedural autonomy of physician trainees. Reviewers worked in duplicate for article selection and data abstraction. Primary measures of interest were self-reported and observer-rated procedural autonomy. Meta-analysis pooled differences in perceptions of procedural autonomy based on trainee gender. RESULTS: The search returned 2,714 articles, of which 16 were eligible for inclusion. These reported data for 6,109 trainees (median, 90 per study) and 2,763 supervisors (median, 54 per study). No studies investigated differences in perceptions of autonomy based on race. In meta-analysis of disparities between genders in autonomy ratings (positive number favoring female trainees), pooled standardized mean differences were -0.12 (95% confidence interval [CI], -0.19 to -0.04; P = .003; n = 10 studies) for trainee self-rated autonomy and -0.05 (95% CI, -0.11 to 0.01; P = .07; n = 9 studies) for supervisor ratings of autonomy. CONCLUSIONS: Limited evidence suggests that female trainees perceived that they received less procedural autonomy than did males. Further research exploring the degree of gender- and race-based differences in procedural autonomy, and factors that influence these differences is warranted.

description: We study properties of ultra-cold bosonic atoms in one, two and three dimensional optical lattices by large scale quantum Monte Carlo simulations of the Bose Hubbard model in parabolic confinement potentials. Local phase structures of the atoms are shown to be accessible via a well defined local compressibility, quantifying a global response of the system to a local perturbation. An indicator for the presence of extended Mott plateaux is shown to stem from the shape of the coherent component of the momentum distribution function, amenable to experimental detection. Additional fine structures in the momentum distribution are found to appear unrelated to the local phase structure, disproving previous claims. We discuss limitations of local potential approximations for confined Bose gases, and the absence of quantum criticality and critical slowing down in parabolic confinement potentials, thus accounting for the fast dynamics in establishing phase coherence in current experiments. In contrast, we find that flat confinement potentials allow quantum critical behavior to be observed already on moderately sized optical lattices. Our results furthermore demonstrate, that the experimental detection of the Mott transition would be significantly eased in flat confinement potentials.

description: In this paper we consider a static and regular fluid generating a locally spherically symmetric and time-independent space-time and calculate the leading quantum corrections to the metric to first order in curvature. Starting from a singularity free classical solution of general relativity, we show that singularities can be introduced in the curvature invariants by quantum gravitational corrections calculated using an effective field theory approach to quantum gravity. We identify non-trivial conditions that ensure that curvature invariants remain singularity free to leading order in the curvature expansion of the effective action.

description: Multilayer insulation (MLI) is an important technique for the reduction of radiation heat load in cryostats. The present work is focused on investigation for the selection of suitable reflective layer and spacer material in MLI systems. In our analysis, we have selected perforated double-Aluminized Mylar (DAM) with Dacron, unperforated DAM with Silk-net and perforated DAM with Glass-tissue for their evaluation as the reflective layer as well as spacer materials in MLI technique. Current work would discuss the calculation of the effect of layer density and the number of layers on the heat load. Knowing the key parameters of MLI, we have compared the heat load generation in spherical as well as cylindrical cryostats and the effect of layering near and outer surface on the heat load.

Optimal Inheritance Taxation under Uncertainty and Tax Frictions

description: The current literature in optimal inheritance taxation does not address two important issues. First, there is significant uncertainty surrounding the receipt of a bequest by heirs. This uncertainty can arise from complications in inheritance law, prospects of future taxes, and conflict among the recipients. Such factors can cause individuals to change how much they consume during their life and how much they leave for their heirs. Second, the costs associated with assessing taxable property and collecting taxes on that property can be significant.
The paper considers a non-overlapping generations model adapted from a 2013 paper by Thomas Piketty and Emmanuel Saez. In this model, utility maximizing individuals receive utility from consump- tion, labor, and bequests left to their heirs and government taxes inheritance and labor income in such a way that they can maximize social welfare through a fixed, redistributive lump sum. We focus on how changes in uncertainty, inheritance tax frictions, and labor- income tax frictions effect the optimal inheritance tax.
We find that an increase in uncertainty causes individuals to con- sume more and leave less for their heirs. This increased uncertainty also lowers the optimal inheritance tax. We also find that increasing the friction on bequest tax decreases the optimal bequest tax, and increasing the friction on labor income tax increases the optimal bequest tax.

description: The paper provides a rare case study of terrorism and counter-terrorism within a closed society, carried out under a blanket of official secrecy. This case is unexpectedly revealing in what it tells us about terrorism, counterterrorism, and the relative strengths of open and closed societies. Documents from the archive of the Lithuania KGB show how the Soviet authorities managed the hunt for the perpetrators of bombing attacks carried out in Moscow in January 1977. Lithuania, a sensitive border region with a troubled history, was far distant from the epicenter of the conspiracy in Soviet Armenia, but the authorities did not know this beforehand, and made considerable efforts to establish or rule out a Lithuanian connection. It was a problem that the KGB, like other Soviet organizations, was vulnerable to boxchecking and other kinds of perfunctory working to the plan. The career concerns of regional KGB leaders appear to have countered this tendency. The paper evaluates the strengths and weaknesses of a counter-terrorist operation carried out under conditions of the intense secrecy that was normal in the Soviet police state.

description: In a recent paper, we pointed out that mixing of the light neutrinos with heavy gauge singlet states could reconcile the Z-pole data from e+e- colliders and the nu_mu (anti-nu_mu) scattering data from the NuTeV experiment at Fermilab. We further noted that the mixing angle required to fit the data is much larger than what would be expected from the conventional seesaw mechanism. In this paper, we show how such mixings can be arranged by a judicious choice of the neutrino mass texture. We also argue that by invoking the unification of the Dirac mass matrix for the up-type quarks and the neutrinos, the mass of the heavy states can naturally be expected to be in the few TeV range. The model is strongly constrained by the lepton flavor changing process mu -> e gamma which requires lepton universality to be violated in the charged channel.

description: We study a four species ecological system with cyclic dominance whose individuals are distributed on a square lattice. Randomly chosen individuals migrate to one of the neighboring sites if it is empty or invade this site if occupied by their prey. The cyclic dominance maintains the coexistence of all the four species if the concentration of vacant sites is lower than a threshold value. Above the treshold, a symmetry breaking ordering occurs via growing domains containing only two neutral species inside. These two neutral species can protect each other from the external invaders (predators) and extend their common territory. According to our Monte Carlo simulations the observed phase transition is equivalent to those found in spreading models with two equivalent absorbing states although the present model has continuous sets of absorbing states with different portions of the two neutral species. The selection mechanism yielding symmetric phases is related to the domain growth process whith wide boundaries where the four species coexist.

description: We study the spontaneous emission rate of a dipole emitter in $\mathcal{PT}$-symmetric environment of two coupled waveguides using the reciprocity approach generalized to non-orthogonal eigenmodes of non-Hermitian systems. Considering emission to the guided modes, we define and calculate the modal Purcell factor composed of contributions of independent and interfering non-orthogonal modes leading to the emergence of cross-mode terms in the Purcell factor. We reveal that the closed-form expression for the modal Purcell factor within the coupled mode theory slightly alters for the non-Hermitian coupled waveguide compared to the Hermitian case. It is true even near the exceptional point, where the eigenmodes coalesce and the Petermann factor goes to infinity. This result is fully confirmed by the numerical simulations of active and passive $\mathcal{PT}$-symmetric systems being the consequence of the mode non-orthogonality.

description: Dark matter may be composed of superWIMPs, superweakly-interacting massive particles produced in the late decays of other particles. We focus on the case of gravitinos produced in the late decays of sleptons or sneutrinos and assume they are produced in sufficient numbers to constitute all of non-baryonic dark matter. At leading order, these late decays are two-body and the accompanying energy is electromagnetic. For natural weak-scale parameters, these decays have been shown to satisfy bounds from Big Bang nucleosynthesis and the cosmic microwave background. However, sleptons and sneutrinos may also decay to three-body final states, producing hadronic energy, which is subject to even more stringent nucleosynthesis bounds. We determine the three-body branching fractions and the resulting hadronic energy release. We find that superWIMP gravitino dark matter is viable and determine the gravitino and slepton/sneutrino masses preferred by this solution to the dark matter problem. In passing, we note that hadronic constraints disfavor the possibility of superWIMPs produced by neutralino decays unless the neutralino is photino-like.

Year: 2014

description: Wheat paper made from discarded wheat straw has become a viable option and alternative that rivals 30% PCW paper in today’s society that is focused on sustainability. In an attempt to improve the sustainability of UBC, wheat paper is to be considered. This report will focus on the triple bottom line assessment of wheat paper to determine if it is acceptable to be used at UBC instead of the standard 30% PCW paper. Three aspects of wheat paper will be reviewed. These include the environmental, economic and social impacts that are associated with how beneficial or consequential wheat paper is compared to 30% PCW paper. Environmental aspects include the amount of energy required to produce the paper, the materials required and the overall life cycle. In terms of economic factors we analysed the costs and its benefits and consequences. Lastly, we examined the social aspects which included labour and benefits and consequences wheat paper can have on society. When performing the analysis many ideas brought up by Minto Roy from Royal Printers in an interview have been taken into account and a transcript is available in the Appendices. It is also assumed that the facilities in India where the wheat paper is made meet all requirements of UBC’s Supplier Code of Conduct. This report ultimately finds that wheat paper is a compelling option for UBC to choose from compared to 30% PCW paper because wheat paper production emits less CO₂ emissions, reduces the amount of trees used in paper compared to 30% PCW by 7 times, may reduce consumer prices on grain products if demand increases, and is available at the same price point.

description: The original Wigner function provides a way of representing in phase space the quantum states of systems with continuous degrees of freedom. Wigner functions have also been developed for discrete quantum systems, one popular version being defined on a 2N x 2N discrete phase space for a system with N orthogonal states. Here we investigate an alternative class of discrete Wigner functions, in which the field of real numbers that labels the axes of continuous phase space is replaced by a finite field having N elements. There exists such a field if and only if N is a power of a prime; so our formulation can be applied directly only to systems for which the state-space dimension takes such a value. Though this condition may seem limiting, we note that any quantum computer based on qubits meets the condition and can thus be accommodated within our scheme. The geometry of our N x N phase space also leads naturally to a method of constructing a complete set of N+1 mutually unbiased bases for the state space.

description: We investigate the Kondo effect with Wilson fermions. This is based on a mean-field approach for the chiral Gross-Neveu model including four-point interactions between a light Wilson fermion and a heavy fermion. For massless Wilson fermions, we demonstrate the appearance of the Kondo effect. We point out that there is a coexistence phase with both the light-fermion scalar condensate and Kondo condensate, and the critical chemical potentials of the scalar condensate are shifted by the Kondo effect. For negative-mass Wilson fermions, we find that the Kondo effect is favored near the parameter region realizing the Aoki phase. Our findings will be useful for understanding the roles of heavy impurities in Dirac semimetals, topological insulators, and lattice QCD simulations.

description: It had been shown that the transition from a rigidly rotating spiral wave to a meandering spiral wave is via a Hopf bifurcation. Many studies have shown that these bifurcations are supercritical, but we present numerical studies which show that subcritical bifurcations are also present within FitzHugh-Nagumo. Furthermore, we present a evidence that this bifurcation is highly sensitive to initial conditions, and it is possible to convert one solution in the hysteresis loop to the other.

description: Research initiatives in hybrid-electric/sustainable aviation typically address only a single vehicle or single vehicle class. However, it can be expected that for novel propulsion and energy solutions to reach a sufficient maturity level an approach not too different from the early days of aviation could be followed: starting small to prove a technology and gradually scaling it up to larger and larger classes of vehicles. Therefore, it is important to sketch a landscape of technologies and identify areas suitable for scaling, as well as limitations or challenges for development. The CHYLA project aims to contribute to the overall research and development in sustainable aviation by providing exactly this; an overview of scaling opportunities, challenges and limitations of key radical technologies where the credibility of underlying technology assumptions is an explicit factor in developing such a landscape. In CHYLA we introduce the concept of “credible aircraft design”, which refers to the influence of the uncertainty in the assumptions behind the design to quantify how realisable, or in other words, how credible, is the design.

description: We consider a percolation process in which $k$ points separated by a distance proportional to system size $L$ simultaneously connect together ($k>1$), or a single point at the center of a system connects to the boundary ($k=1$), through adjacent connected points of a single cluster. These processes yield new thresholds $\overline p_{ck}$ defined as the average value of $p$ at which the desired connections first occur. These thresholds are not sharp as the distribution of values of $p_{ck}$ for individual samples remains broad in the limit of $L \to \infty$. We study $\overline p_{ck}$ for bond percolation on the square lattice, and find that $\overline p_{ck}$ are above the normal percolation threshold $p_c = 1/2$ and represent specific supercritical states. The $\overline p_{ck}$ can be related to integrals over powers of the function $P_\infty(p)$ equal to the probability a point is connected to the infinite cluster; we find numerically from both direct simulations and from measurements of $P_\infty(p)$ on $L\times L$ systems that, for $L \to \infty$, $\overline p_{c1} = 0.51755(5)$, $\overline p_{c2} = 0.53219(5)$, $\overline p_{c3} = 0.54456(5)$, and $\overline p_{c4} = 0.55527(5).$ The percolation thresholds $\overline p_{ck}$ remain the same, even when the $k$ points are randomly selected within the lattice. We show that the finite-size corrections scale as $L^{-1/ν_k}$ where $ν_k = ν/(k β+1)$, with $β=5/36$ and $ν=4/3$ being the ordinary percolation critical exponents, so that $ν_1= 48/41$, $ν_2 = 24/23$, $ν_3 = 16/17$, $ν_4 = 6/7$, etc. We also study three-point correlations in the system, and show how for $p>p_c$, the correlation ratio goes to 1 (no net correlation) as $L \to \infty$, while at $p_c$ it reaches the known value of 1.022.

description: This paper outlines a model for pricing options when the underlying futures pnce exhibits time-varying volatility. Futures price movements are characterized using a GARCH model. In an empirical application, the GARCH option pricing model predicts market premmms significantly better than the standard Black model, which assumes volatility is constant.

Electronic correlation effects and local magnetic moments in L1$_0$ phase of FeNi

description: We study the electronic and magnetic properties of L1$_0$ phase of FeNi, a perspective rare-earth-free permanent magnet, by using a combination of density functional and dynamical mean-field theory. Although L1$_0$ FeNi has a slightly tetragonally distorted fcc lattice, we find that magnetic properties of its constituent Fe atoms resemble those in pure bcc Fe. In particular, our results indicate the presence of well-localized magnetic moments on Fe sites, which are formed due to Hund's exchange. At the same time, magnetism of Ni sites is much more itinerant. Similarly to pure bcc Fe, the self-energy of Fe $3d$ states is found to show the non-Fermi-liquid behavior. This can be explained by peculiarities of density of Fe $3d$ states, which has pronounced peaks near the Fermi level. Our study of local spin correlation function and momentum dependence of particle-hole bubble suggests that the magnetic exchange in this substance is expected to be of RKKY-type, with iron states providing local-moment contribution, and the states corresponding to nickel sites (including virtual hopping to iron sites) providing itinerant contribution.

description: The objective of this paper is to determine whether optionbased probability assessments become reliable through time. The reliability of soybean and corn option-based probability assessments is evaluated during 1985-1987 and 1988-1990. Soybean probability assessments become reliable in the later period. Corn probability assessments are reliable in both time periods.

description: We study the dynamic network of relationships among avatars in the massively multiplayer online game Planetside 2. In the spring of 2014, two separate servers of this game were merged, and as a result, two previously distinct networks were combined into one. We observed the evolution of this network in the seven month period following the merger and report our observations. We found that some structures of original networks persist in the combined network for a long time after the merger. As the original avatars are gradually removed, these structures slowly dissolve, but they remain observable for a surprisingly long time. We present a number of visualizations illustrating the post-merger dynamics and discuss time evolution of selected quantities characterizing the topology of the network.

Periodic Anderson model with degenerate orbitals: linearized dynamical mean field theory approach

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We investigate a multi-orbital extension of the periodic Anderson model with particular emphasis on electron correlations including orbital fluctuations. By means of a linearized version of the dynamical mean-field theory, we compute the renormalization factor, the density of states, the spectral gap and the local correlation functions for a given set of the intra- and inter-orbital Coulomb interactions as well as the Hund coupling. It is found that when a certain condition is met for the intra- and inter-orbital interactions for $f$ electrons, orbital fluctuations are enhanced, thereby enlarging the Kondo insulating gap. This effect is suppressed in the presence of the Hund coupling. We also clarify how the Kondo insulator is continuously changed to the Mott insulator when electron correlations among conduction electrons are increased.

Glassy correlations and microstructures in randomly crosslinked homopolymer blends

Publisher: name: arXiv
Year: 2005
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We consider a microscopic model of a polymer blend that is prone to phase separation. Permanent crosslinks are introduced between randomly chosen pairs of monomers, drawn from the Deam-Edwards distribution. Thereby, not only density but also concentration fluctuations of the melt are quenched-in in the gel state, which emerges upon sufficient crosslinking. We derive a Landau expansion in terms of the order parameters for gelation and phase separation, and analyze it on the mean-field level, including Gaussian fluctuations. The mixed gel is characterized by thermal as well as time-persistent (glassy) concentration fluctuations. Whereas the former are independent of the preparation state, the latter reflect the concentration fluctuations at the instant of crosslinking, provided the mesh size is smaller than the correlation length of phase separation. The mixed gel becomes unstable to microphase separation upon lowering the temperature in the gel phase. Whereas the length scale of microphase separation is given by the mesh size, at least close to the transition, the emergent microstructure depends on the composition and compressibility of the melt. Hexagonal structures, as well as lamellae or random structures with a unique wavelength, can be energetically favorable.

The rational, loving and responsible parent. A discursive construction of the identities of the parents that decided not to vaccinate their children
Creators: name: Toth, Cosmin
Publisher: name: figshare
Year: 2020
Subjects: subject: Sociology
subject: FOS: Sociology

description: My objective in this article is to identify what types of identities are constructed and claimed in the context of sociological interviews taken from parents who have decided not to vaccinate at least one of their children. Analyzing the interviews taken, I managed to show that one of the most prominent identities displayed and claimed in the interviews was that of the loving, responsible and rational parent. This constructive identity was based on several interpretative sub-repertoires such as: the transition from the ignorant and credulous parent to the knowing parent repertoire, the responsible and loving parent repertoire, the balanced medical decisions repertoire, the proper documentation repertoire, disclaimer of any anti vaccine militancy repertoire, rejecting any risk out of love repertoire. I concluded that this type of identity construction constitutes a restorative repertoire through which the parents try to regain the identity of the rational, responsible and loving parent and consequently reclaiming the uncontestable right of decision regarding their own children.
