description: Since the turn of the twenty-first century, developed countries have engaged in a race for the best and the brightest. States have been lowering barriers to entry and actively recruiting talent from abroad as the premium on human capital has increased in today’s knowledge economies and as demographic problems due to aging and low fertility are becoming a reality. What is interesting is that formerly immigration-adverse, non-traditional immigration states are now opening their doors to this pool of highly skilled migrants. From permanent residency to temporary visas not requiring employer sponsorship, states attempt to sweeten their offers to global talent so the latter would come to their shores. Even more interestingly, notwithstanding the current global economic turmoil, states continue to invite and retain well-educated migrants, while low-skilled migrant labor is turned away. This paper analyses immigration policies since the beginning of the global financial crisis in 2008. Based on this background, the paper presents a non-linear dynamic model where the attraction of global talent is influenced by both countries’ immigration policies and the stock of highly-educated migrants. The model is used to simulate the effects of loosened immigration restrictions on the accumulation of global talent.

description: We show that the double copy of gauge theory amplitudes to $\mathcal{N}=0$ supergravity amplitudes extends from tree level to loop level. We first explain that color-kinematic duality is a condition for the Becchi-Rouet-Stora-Tyutin operator and the action of a field theory with cubic interaction terms to double copy to a consistent gauge theory. We then apply this argument to Yang-Mills theory, where color-kinematic duality is known to be satisfied onshell at tree level. Finally, we show that the latter restriction can only lead to terms that can be absorbed in a sequence of field redefinitions, rendering the double copied action equivalent to $\mathcal{N}=0$ supergravity.

description: The interest of this study is the tradeoff between nutrition and taste in consumer food choice. We examine choice between more and less healthy versions of particular foods within four important grocery categories: breakfast cereal, milk, bread, and soft drinks. Within a category, products do not greatly differ in terms of cost and convenience, and nutritional differences are easily determined. Consumers are less likely to choose unhealthy foods due to cost or convenience advantages, or through ignorance. This makes the choice between taste and nutrition more apparent. We use annual expenditure data reported by a large sample of households participating in the AC Nielsen Homescan data system. For each of the food categories we develop a measure of ‘healthiness’ of household expenditures. This is regressed on household demographics and a measure of market prices. We find that households with college-educated heads and higher income households make significantly healthier choices in all the categories. The former was expected. However, although income is generally associated with healthier diets, this is usually attributed to the cost of healthy foods, an explanation inapplicable here. This suggests a deeper understanding of the role of income in diet is needed. As expected, the presence of children leads to a lowering of household nutrition, but primarily for cereal and bread: beverages are little affected. Older households tend to make healthier choices. Finally, we find a reasonably strong role for prices, perhaps reflecting high substitutability among products whose major difference essentially involves a single dimension.
Limits of dark energy measurements from CMB lensing-ISW-galaxy count correlations

Subjects: subject: Astrophysics (astro-ph)

description: I discuss several issues that arise when trying to constrain the dark energy equation of state using correlations of the integrated Sachs-Wolfe effect with galaxy counts and lensing of the cosmic microwave background. These techniques are complementary to others such as galaxy shear surveys, and can use data that will already be obtained from currently planned observations. In regimes where cosmic variance and shot noise are the dominant sources of error, constraints could be made on the mean equation of state to within 0.33 and its first derivative to within 1.0. Perhaps more interesting is that the determination of dark energy parameters by these types of experiments depends strongly on the presence or absence of perturbations in the dark energy fluid.

Semi-annihilating $Z_3$ Dark Matter for XENON1T Excess

description: The recently reported result from XENON1T experiment indicates that there is an excess with $3.5σ$ significance in the electronic recoil events. Interpreted as new physics, new sources are needed to account for the electronic scattering. We show that a dark fermion $ψ$ with mass about $ \mathcal{O}\left(10\right)$ MeV from semi-annihilation of $Z_3$ dark matter $X$ and subsequent decay of a dark gauge boson $V_μ$ may be responsible for the excess. The relevant semi-annihilation process is $X+X\rightarrow \overline{X}+V_μ(\rightarrow ψ+ \overlineψ)$, in which the final $ψ$ has a box-shape energy spectrum. The fast-moving $ψ$ can scatter with electron through an additional gauge boson that mixes with photon kinetically. The shape of the signals in this model can be consistent with the observed excess. The additional interaction with proton makes this model testable in future searches for nucleus recoil as well. Because of the lightness of invisible particle introduced, this scenario requires non-standard cosmology to accommodate the additional radiation component.

description: The deep imaging of the field of an observed lensing event by a cosmic string reveals many additional lensing events. We study the statistics of such string lensing. We derive explicit expressions for the distributions of image separations of lensing by a cosmic string and point out that they are quite sensitive to parameters which characterize the cosmic string, such as the redshift and tension of the cosmic string. Thus the statistics of string lensing events add new important information on the cosmic string which cannot be obtained from the detailed investigation of one lensing event.

Computing the heat conductivity of fluids from density fluctuations

description: Equilibrium molecular dynamics simulations, in combination with the Green-Kubo (GK) method, have been extensively used to compute the thermal conductivity of liquids. However, the GK method relies on an ambiguous definition of the microscopic heat flux, which depends on how one chooses to distribute energies over atoms. This ambiguity makes it problematic to employ the GK method for systems with non-pairwise interactions. In this work, we show that the hydrodynamic description of thermally driven density fluctuations can be used to obtain the thermal conductivity of a bulk fluid unambiguously, thereby bypassing the need to define the heat flux. We verify that, for a model fluid with only pairwise interactions, our method yields estimates of thermal conductivity consistent with the GK approach. We apply our approach to compute the thermal conductivity of a non-pairwise additive water model at supercritical conditions, and then of a liquid hydrogen system described by a machine-learning interatomic potential, at 33 GPa and 2000 K.

description: People with low incomes tend to make less healthy consumption choices than do high income people. In the case of food, agricultural economists have investigated whether this is due to the cost of a healthy diet. Studies of various aspects of the nutrition-income nexus have generally been inconclusive. We investigate a different possibility, motivated by the fact that low income individuals are most likely to be smokers, which cannot be due to limited budgets. Drawing on a body of related literature, we develop a model in which income serves not only as a budget constraint but also as a source of future utility. We test the model by estimating logistic models of beginning and quitting smoking. We find support for the idea that low income consumers make less healthy choices because they face lower costs in terms of foregone future utility.
Deposition of particle pollution in turbulent forced-air cooling

Year: 2020
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: Rotating fans are the prevalent forced cooling method for heat generating equipment and buildings. As the concentration of atmospheric pollutants has increased, the accumulation of microscale and nanoscale particles on surfaces due to advection-diffusion has led to adverse mechanical, chemical and electrical effects that increase cooling demands and reduce the reliability of electronic equipment. Here, we uncover the mechanisms leading to enhanced deposition of particle matter (PM$_{10}$ and PM$_{2.5}$) on surfaces due to turbulent axial fan flows operating at Reynolds numbers, $Re \sim 10^5$. Qualitative observations of long-term particle deposition from the field were combined with \textit{in situ} particle image velocimetry on a telecommunications base station, revealing the dominant role of impingement velocity and angle. Near-wall momentum transport for $10 < y^+ < 50$ were explored using a quadrant analysis to uncover the contributions of turbulent events that promote particle deposition through turbulent diffusion and eddy impaction. By decomposing these events, the local transport behaviour of fine particles from the bulk flow to the surface has been categorised. The transition from deposition to clean surfaces was accompanied by a decrease in shear velocity, turbulent stresses, and particle sweep motions with lower flux in the wall-normal direction. Finally, using these insights, selective filtering of coarse particles was found to promote the conditions that enhance the deposition of fine particle matter.
title: Impact of English language barriers on HORECA businesses

description: In diesem Forschungsbericht wird untersucht, wie sich englische Sprachbarrieren auf Arbeitszufriedenheit, Frustration, Rollenunklarheit und Vertrauenswürdigkeit bei Arbeitnehmern in der HORECA-Branche auswirken. Zunächst wird eine Literaturrecherche durchgeführt, um die vorliegenden Probleme hervorzuheben. Anschließend wird die Methodik der Studie vorgestellt und besteht aus einer Umfrage, die darauf abzielt, die benötigten Daten für die statistischen Tests zu sammeln. Diese Umfrage wurde in drei verschiedenen Facebook-Gruppen mit jeweils mehr als 3500 Befragten verteilt. Die Antworten von 109 Befragten wurden für die abschließende Analyse in R verwendet. Die erstellten Balkendiagramme zeigen die Ergebnisse wie folgt. Erstens ist die Rollenunklarheit bei Arbeitnehmern, die angeben, am Arbeitsplatz nicht fließend Englisch zu sprechen, deutlich häufiger anzutreffen. Zweitens besteht auch ein starker Zusammenhang zwischen Vertrauenswürdigkeit und Sprachkenntnissen sowie Verwirrung aufgrund von ELB. Schließlich hängt das Gefühl der Frustration eindeutig mit mangelnden Sprachkenntnissen zusammen. Ein Vorschlag zur Lösung dieser Probleme ist die Einführung von Englisch-Sprachschulungen durch HORECA-Unternehmen. Dies kann die Zufriedenheit mit der Sprache steigern, die Vertrauenswürdigkeit verbessern und Rollenunklarheiten reduzieren.
description: This research paper investigates how English Language Barriers affect job satisfaction, frustration, role ambiguity and trustworthiness among workers in the HORECA industry. First, a literature review is performed for underlining the issues at hand. Then the methodology of the study is introduced and consists of a survey that was designed to collect the needed data for the statistical tests. This survey was distributed in 3 different Facebook groups with more than 3500 respondents each. The answers of 109 respondents were used to perform the final analysis in R. The created bar charts show the results as follows. First, role ambiguity is clearly more prevalent among workers who report not being fluent in their use of English at work. Second, a strong relationship between trustworthiness and language skills and confusion due to ELB is also prevalent. Lastly, the feeling of frustration is clearly associated to lack of language skills. A proposal in solving the issues is implementing English language trainings by HORECA businesses. This can enhance language satisfaction, improve trustworthiness and reduce role ambiguity.

description: We study the excited random walk, in which a walk that is at a site that contains cookies eats one cookie and then hops to the right with probability p and to the left with probability q=1-p. If the walk hops onto an empty site, there is no bias. For the 1-excited walk on the half-line (one cookie initially at each site), the probability of first returning to the starting point at time t scales as t^{-(2-p)}. Although the average return time to the origin is infinite for all p, the walk eats, on average, only a finite number of cookies until this first return when p<1/2. For the infinite line, the probability distribution for the 1-excited walk has an unusual anomaly at the origin. The positions of the leftmost and rightmost uneaten cookies can be accurately estimated by probabilistic arguments and their corresponding distributions have power-law singularities near the origin. The 2-excited walk on the infinite line exhibits peculiar features in the regime p>3/4, where the walk is transient, including a mean displacement that grows as t^{nu}, with nu>1/2 dependent on p, and a breakdown of scaling for the probability distribution of the walk.

description: Objective: Field data have shown significant benefit from driver airbag for occupant protection in frontal crashes. However, vehicle modifiers almost always permanently deactivate airbags for wheelchair-seated drivers. The objective of this study was to conduct sled tests and computational simulations to answer whether driver airbags should be deactivated for drivers seated in wheelchairs. Methods: Five sled tests were conducted under a 48-kph 20-g frontal crash pulse all with driver airbag. Seat-belt fit (good, poor, and unbelted), airbag deployment time (proper and late), and occupant size (midsize male and small female HIII ATDs) were varied in the tests. The 2006 Chrysler Town-and-Country minivan was selected as the nominal vehicle environment, and a surrogate wheelchair with a docking securement system was used for all sled tests. ATD injury measures for the head, neck, chest, and lower extremities were recorded in each test, and were used for validating a set of MADYMO models. Parametric studies with a total of 28 MADYMO simulations were then conducted to investigate the airbag effects on occupant injury risks with varied occupant size, belt fit, and impact angle (0, 15, and 30 deg). Results: The sled tests showed potential safety concerns for wheelchair-seated drivers with a poor belt fit or without a belt. Specifically, the unbelted midsize male ATD sustained high femur forces and the small female ATD with poor belt fit sustained high chest deflections. The parametric simulations showed that airbag generally improved the protection for wheelchair-seated drivers. It is especially useful for unbelted wheelchair-seated drivers, and is also helpful for reducing the head and neck injury risks regardless of the belt condition, occupant size, and impact angle. Conclusions: This is the first study using sled tests and computational simulations to investigate the effects of airbag deployment on injury risks of wheelchair-seated drivers. Overall, the results showed little basis for concern that the energy of deploying a driver airbag in today’s vehicles will cause serious-to-fatal injuries to drivers seated in wheelchairs. The results of this study therefore support the idea that driver airbags generally offer tangible safety benefits for a wide range of wheelchair-seated drivers in frontal crashes.

description: Thermodynamic and magnetic properties of Ising models defined on the triangular Apollonian network are investigated. This and other similar networks are inspired by the problem of covering an Euclidian domain with circles of maximal radii. Maps for the thermodynamic functions in two subsequent generations of the construction of the network are obtained by formulating the problem in terms of transfer matrices. Numerical iteration of this set of maps leads to exact values for the thermodynamic properties of the model. Different choices for the coupling constants between only nearest neighbors along the lattice are taken into account. For both ferromagnetic and anti-ferromagnetic constants, long range magnetic ordering is obtained. With exception of a size dependent effective critical behavior of the correlation length, no evidence of asymptotic criticality was detected.

description: This paper presents a novel calibration algorithm for Multi-Focus Plenoptic Cameras (MFPCs) using raw images only. The design of such cameras is usually complex and relies on precise placement of optic elements. Several calibration procedures have been proposed to retrieve the camera parameters but relying on simplified models, reconstructed images to extract features, or multiple calibrations when several types of micro-lens are used. Considering blur information, we propose a new Blur Aware Plenoptic (BAP) feature. It is first exploited in a pre-calibration step that retrieves initial camera parameters, and secondly to express a new cost function for our single optimization process. The effectiveness of our calibration method is validated by quantitative and qualitative experiments.

description: Many internet applications are powered by machine learned models, which are usually trained on labeled datasets obtained through either implicit / explicit user feedback signals or human judgments. Since societal biases may be present in the generation of such datasets, it is possible for the trained models to be biased, thereby resulting in potential discrimination and harms for disadvantaged groups. Motivated by the need for understanding and addressing algorithmic bias in web-scale ML systems and the limitations of existing fairness toolkits, we present the LinkedIn Fairness Toolkit (LiFT), a framework for scalable computation of fairness metrics as part of large ML systems. We highlight the key requirements in deployed settings, and present the design of our fairness measurement system. We discuss the challenges encountered in incorporating fairness tools in practice and the lessons learned during deployment at LinkedIn. Finally, we provide open problems based on practical experience.

description: We report on the electronic properties of few interacting electrons confined in a parabolic quantum dot based on a theoretical approach developed to investigate the influence of Bychkov-Rashba spin-orbit (SO) interaction on such a system. We note that the spin-orbit coupling profoundly influences the energy spectrum of interacting electrons in a quantum dot. Here we present accurate results for the energy levels and optical-absorption spectra for parabolic quantum dots containing upto four interacting electrons, in the presence of spin-orbit coupling and under the influence of an externally applied, perpendicular magnetic field. We have described in detail about a very accurate numerical scheme to evaluate these quantities. We have evaluated the effects of SO coupling on the Fock-Darwin spectra for quantum dots made out of three different semiconductor systems, InAs, InSb, and GaAs.

Mathematically the theorem builds upon the standard theory of averaging in non-linear dynamical systems.

description: Since 2003, the NEPAD Comprehensive Africa Agriculture Development Programme (CAADP) has been endorsed by African Heads of State and Governments as a vision for the restoration of agricultural growth, food security, and rural development in Africa. The program aims at stimulating agriculture-led development that eliminates hunger and reduces poverty and food insecurity. As pointed out by Etro (2001), the creation of a union or adoption of a common agenda should move the equilibrium toward the first best solution whenever policies generate spillovers. This arises because the ability of a common agenda to reduce the scope of free-riding behavior among member countries. In addition, increasing world market integration leads to more externalities which call for policy coordination and supernational jurisdictions (Spolaore and Wacziarg, 2000). Using Spatial Durbin Model for panel data, the paper intends to investigate the presence of externalities in agricultural production within sub-Saharan African countries to validate the rationale for initiating CAADP. The model is estimated for the 1961-2006 period as well as sub-periods between 1961 and 2006. Over time, the results confirm the existence of positive and significant agricultural spillover. The findings suggest that the speed of convergence is faster when accounting for agricultural production spillover across countries.

description: In the current literature, there is a lack of research information concerning the impact that the school accreditation process can have, including through the generated insights, and the potential transformational journeys, of a diverse group of stakeholders with a shared purpose. The research offers unique insights, via a case study, of an Indian International School undergoing joint accreditation (Council of International Schools, New England Association of International School, and International Baccalaureate). As this was a case study, the sample size was 5. The Research Question is: What is the impact of the NEASC accreditation process on meeting the needs of twenty-first-century students? The researcher, as the school's Head of Design and Technology, and also a foreigner, remains close to the action of the participants, recording different insights of various stakeholders via anecdotal notes, regarding the effects and effectiveness of the accreditation process at the school. Additionally, as this accreditation process occurred during COVID-19 the case study reveals various stakeholders’ perspectives conducted as face to face, online and hybrid. The researcher connects case study findings within the larger research framework of school accreditations, including digital transformations and global trends; to offer fresh perspectives and value to the field.

description: In this paper we analyse the Bianchi IX Universe dynamics within the corner region associated to the potential term which the spatial curvature induces in the Minisuperspace. The study is done in the vacuum and in the presence of a massless scalar field $ϕ$ and a cosmological constant term $Λ$. We investigate the dynamics in terms of WKB scenario for which the isotropic Misner variables (the volume) and one of the two anisotropic ones (and $ϕ$ when present) are treated on a semi-classical level, while the remaining anisotropy degree of freedom, the one trapped in the corner, is described on a pure quantum level. The quantum dynamics always reduces to the one of a time-dependent Schröedinger equation for a harmonic potential with a time dependent frequency. The vacuum case is treated in the limits of a collpasing and an expanding Universe, while the dynamics in presence of $ϕ$ and $Λ$ is studied for $t \rightarrow \infty $. In both analysis the quantum dynamics of the anisotropy variable is associated to a decaying standard deviation of its probability density, corresponding to a suppression of the quantum anisotropy associated. In the vacuum case, the corner configuration becomes an attractor for the dynamics and the evolution resembles that one of a Taub cosmology in the limit of a non-singular initial Universe. This suggests that if the Bianchi dynamics enters enough the potential corner then the initial singularity is removed and a Taub picture emerges. The case when $ϕ$ is present well mimics the De-Sitter phase of an inflationary Universe. Here we show that both the classical and quantum anisotropies are exponentially suppressed, so that the resulting dynamics corresponds to an isotropic closed Robertson-Walker geometry.

description: Spin waves - the elementary excitations of magnetic materials - are prime candidate signal carriers for low dissipation information processing. Being able to image coherent spin-wave transport is crucial for developing interference-based spin-wave devices. We introduce a platform for probing coherent spin waves based on magnetic resonance imaging with electron spins in diamond. Focusing on a thin-film magnetic insulator, we quantify spin-wave amplitudes, visualize the dispersion, and demonstrate time-domain measurements of spin-wave packets. We use our platform to study spin-wave interference, revealing uni-directional, autofocused spin-wave patterns with frequency-controlled numerical apertures. A theoretical analysis explains the patterns in terms of chiral spin-wave excitation and stray-field coupling to the sensor spins. These results pave the way for probing spin waves in atomically thin magnets, even when embedded between opaque materials.

description: We employ the light-cone superspace formalism to develop an efficient approach to constructing superconformal operators of twist two in Yang-Mills theories with N=1,2,4 supercharges. These operators have an autonomous scale dependence to one-loop order and determine the eigenfunctions of the dilatation operator in the underlying gauge theory. We demonstrate that for arbitrary N the superconformal operators are given by remarkably simple, universal expressions involving the light-cone superfields. When written in components field, they coincide with the known results obtained by conventional techniques.

description: Using direct numerical simulation we study the behavior of the maximal Lyapunov exponent in thin-layer turbulence, where one dimension of the system is constrained geometrically. Such systems are known to exhibit transitions from fully three dimensional turbulence through a mixed two and three dimensional phenomenology state and then onto fully two dimensional dynamics. We find a discontinuous jump in the Lyapunov exponent at this second transition implying the predictability of such systems can change dramatically. Such transitions are seen in a number of different turbulent systems, for example those undergoing strong rotation, hence these results may be relevant for the predictability of complicated real world flows. The Lyapunov exponent is found to provide a particularly clear measure of the transition to two dimensional dynamics. Finally, the application of these results to atmospheric predictability with regard to high-resolution modeling is examined.

description: Farm milk prices in the United States fluctuated throughout the 2000-2009 decade. Dairy farmers, industry pundits, and policymakers all reacted with much alarm. One point of concern has been the response of retail prices to farm price volatility. This study investigates farm-to-retail price transmission for two major dairy products – whole milk and Cheddar cheese – in the 2000s. Results show that price shocks at the farm gate were transmitted asymmetrically to retail. However, in order to best identify the nature of the transmission process, it is important to fit alternative model specifications.
An OOEM-based goal modeling
Creators: name: Wang, Weida
Publisher: name: University of British Columbia
Year: 2009

description: Increasing amounts of research have been exploring methods of handling workflow exceptions by introducing goals into the workflow, as clear goals assist in managing the motivation and habits of employees and departments. However, most existing goal-driven mechanisms have adopted the assumption that the task of identifying goals is a straightforward process, without examining the processes whereby goals are determined. In order to overcome the inadequacy of methods for identifying workflow goals, we propose a goal modeling approach based on Object-Oriented Enterprise Modeling (OOEM), incorporating both the Object-Oriented Workflow Model (OOWM) and the Linguistic Negation Interpretation. In the process of constructing this goal modeling method, we first review literature from previous studies and definitions of some common terms and concepts used for this modeling. Subsequently, we present detailed rules and steps of OOEM-based goal modeling. In addition, we illustrate how this method can be applied to identify goals in business processes. Finally, a small-scale empirical study is conducted to demonstrate the usefulness and practicability of this modeling method. The OOEM-based goal modeling method is a comparatively systematic way to identify a complete hierarchy of goals in business processes, structured in four layers from the level of activities to the level of the entire system. Another novelty of OOEM-based goal modeling is its bottom-up approach: higher-level goals are identified by systematically grouping lower-level goals.

description: Slotting fees are fixed charges paid by food manufacturers to retailers for access to the retail market. The role of the practice and its effects on market efficiency are highly controversial. To date, the literature has focused on the effect of the practice on retail prices; however, slotting allowances also have the potential to alter the range of products available to consumers. Our analysis reveals that the strategic use of slotting allowances by oligopoly firms leads to a superior allocation of product variety among retailers. Indeed, absent price effects, we show that slotting allowances lead to the socially optimal provision of product variety.

description: On the basis of quantum Monte Carlo (QMC) simulations we study the formation of Mott domains in the one-dimensional Hubbard model with an additional confining potential. We find evidences of quantum critical behavior at the boundaries of the Mott-insulating regions. A local compressibility defined to characterize the local phases exhibits a non-trivial critical exponent on entering the Mott-insulating domains. Both the local compressibility and the variance of the local density show universality with respect to the confining potential. We also study the momentum distribution function of the trapped system, and determine its phase diagram.

description: Estimation of third-order statistics relies on the availability of a huge amount of data records, which can pose severe challenges on the data collecting hardware in terms of considerable storage costs, overwhelming energy consumption, and unaffordably high sampling rate especially when dealing with high-dimensional data such as wideband signals. To overcome these challenges, this paper focuses on the reconstruction of the third-order cumulants under the compressive sensing framework. Specifically, this paper derives a transformed linear system that directly connects the cross-cumulants of compressive measurements to the desired third-order statistics. We provide sufficient conditions for lossless third-order statistics reconstruction via solving simple least-squares, along with the strongest achievable compression ratio. To reduce the computational burden, we also propose an approach to recover diagonal cumulant slices directly from compressive measurements, which is useful when the cumulant slices are sufficient for the inference task at hand. All the proposed techniques are tested via extensive simulations. The developed joint sampling and reconstruction approach to third-order statistics estimation is able to reduce the required sampling rates significantly by exploiting the cumulant structure resulting from signal stationarity, even in the absence of any sparsity constraints on the signal or cumulants.
