description: The standard theory that the first-best tax on pollution is equal to marginal environmental damages has been extended in two directions. First, many polluting activities are difficult to tax because they are not market transactions, and so recent papers have shown that the same effects can be achieved by use of a two-part instrument – a tax on one market transaction such as output or income and a subsidy to a different market transaction that is a clean alternative to pollution. It is a generalization of a deposit-refund system. Second, a different literature concerns the second-best optimal pollution tax in the presence of other tax distortions. Here, we combine the two extensions by looking at the second-best two-part instrument (2PI). When government needs revenue, is the deposit larger and the rebate smaller? We find explicit solutions for each tax and subsidy in a general equilibrium model with other tax distortions, and we compare these to the rates in a first-best model. The tax-subsidy combination is explained in terms of a tax effect, an environmental effect, and a revenue effect. The model allows for flexible interpretation, to show various applications of the 2PI. We also discuss important caveats, cases where the 2PI may not be appropriate.

description: In this paper we investigate the impact of environmental regulation on productivity using a Cobb-Douglas production function framework. Estimating the effects of regulation on productivity can be done with a top-down approach using data for broad sectors of the economy, or a more disaggregated bottom-up approach. Our study follows a bottom-up approach using data from the U.S. paper, steel, and oil industries. We measure environmental regulation using plant-level information on pollution abatement expenditures, which allows us to distinguish between productive and abatement expenditures on each input. We use annual Census Bureau information (19791990) on output, labor, capital, and material inputs, and pollution abatement operating costs and capital expenditures for 68 pulp and paper mills, 55 oil refineries, and 27 steel mills. We find that pollution abatement inputs generally contribute little or nothing to output, especially when compared to their ‘productive’ equivalents. Adding an aggregate pollution abatement cost measure to a Cobb-Douglas production function, we find that a $1 increase in pollution abatement costs leads to an estimated productivity decline of $3.11, $1.80, and $5.98 in the paper, oil, and steel industries respectively. These findings imply substantial differences across industries in their sensitivity to pollution abatement costs, arguing for a bottom-up approach that can capture these differences. Further differentiating plants by their production technology, we find substantial differences in the impact of pollution abatement costs even within industries, with higher marginal costs at plants with more polluting technologies. Finally, in all three industries, plants concentrating on change-in-production-process abatement techniques have higher productivity than plants doing predominantly end-of-line abatement, but also seem to be more affected by pollution abatement operating costs. Overall, our results point to the importance using detailed, disaggregated analyses, even below the industry level, when trying to model the costs of forcing plants to reduce their emissions.

description: We examine the incidence, form, and research consequences of measurement error in measures of fatal injury risk in U.S. workplaces using both BLS and NIOSH data. These data are commonly used in hedonic wage studies. Despite the fact that each of our measures of job risk purport to measure the same thing – the risk of a fatality while on the job – the various measures of job risk are not highly correlated, with the maximum correlation being 0.53. Indeed, many of the estimated value of statistical life estimates are negative. We find that the National Institute of Safety and Health’s industry risk measure produces implicit value of life estimates most in line with both economic theory and the mode result for the existing literature than other risk measures examined. Because we find non-classical measurement error that differs across risk measures and is not independent of other regressors, innovative statistical procedures need be applied to obtain statistically improved estimates of wage-fatality risk tradeoffs.

description: The extraordinary Hall effect coefficients $R_s(T)$ of the canonical spin glass alloys ${\bf Au}Fe 8 at%$ and ${\bf Au}Mn 8 at%$ and of an archetype reentrant system ${\bf Au}Fe 18 at%$ were measured as functions of temperature. The data show a critical cusp-like term superimposed on a smooth background for the spin glasses, and change of sign with temperature for the reentrant. The results can be interpreted consistently by invoking a chiral Hall effect contribution as proposed by Kawamura.

description: The aim of this paper is to analyze the relationship between different types of uncertainty and stock returns of the renewable energy and the oil & gas sectors. We use the quantile regression approach developed by Koenker and d’Orey (1987; 1994) to assess which uncertainties are the potential drivers of stock returns under different market conditions. We find that the bioenergy and the oil & gas sectors are most sensitive to uncertainties. Both sectors are affected by financial, euro currency, geopolitical and economic policy uncertainties. Our results have several policy implications. Climate policy makers can prioritize policies that support bioenergy in order to reduce the potentially negative effects of uncertainties on bioenergy investment. Investors aiming to diversify their portfolio should be aware that many uncertainties are common drivers of bioenergy and oil & gas returns, the connectedness between assets of these energy types could therefore increase when uncertainty increases.

description: The Pollution Abatement Costs and Expenditures (PACE) Survey provides the only comprehensive source of data on polluation costs by manufacturing facilities in the U.S. Collected historically by the Bureau of Census until 1994, the U.S. Environmental Protection Agency’s (EPA) National Center for Environmental Economics initiated an agreement with the Bureau of Census to reinstitute the survey with the collection of 1999 data. This paper provides a brief history of the survey, including uses of the data by the EPA. We then discuss the issues we encountered with regard to scope and measurement concerns when redesigning the 1999 survey. The paper concludes with thoughts regarding the future direction of the PACE survey at the EPA.

Repulsive and attractive depletion forces mediated by nonadsorbing polyelectrolytes in the Donnan limit

description: In mixtures of colloids and nonadsorbing polyelectrolytes, a Donnan potential arises across the region between surfaces that are depleted of polyelectrolyte and the rest of the system. This Donnan potential tends to shift the polyelectrolyte density profile towards the colloidal surface and leads to local accumulation of polyelectrolytes. We derive a zero-field theory for the disjoining pressure between two parallel flat plates. Polyelectrolyte is allowed to enter the confined interplate region at the cost of a conformational free energy penalty. The resulting disjoining pressure shows a crossover to a repulsive regime when the interplate separation gets smaller than the size of the polyelectrolyte chain, followed by an attractive part. We find a quantitative match between the model and self-consistent field computations that take into account the full Poisson-Boltzmann electrostatics.

We find that the differential charm cross section can be enhanced up to a factor of 4-5 at low $p_T$. The enhancement is quite sensitive to the charm quark mass and the renormalization/factorization scales.

The Occurrence of the Hall--Instability in Crusts of Isolated Neutron Stars

Year: 2003

description: In former papers we showed that during the decay of a neutron star's magnetic field under the influence of the Hall--drift, an unstable rise of small--scale field structures at the expense of the large--scale background field may happen. This linear stability analysis was based on the assumption of a uniform density throughout the neutron star crust, whereas in reality the density and all transport coefficients vary by many orders of magnitude. Here, we extend the investigation of the Hall--drift induced instability by considering realistic profiles of density and chemical composition, as well as background fields with more justified radial profiles. Two neutron star models are considered differing primarily in the assumption on the core matter equation of state. For their cooling history and radial profiles of density and composition we use known results to infer the conductivity profiles. These were fed into linear calculations of a dipolar field decay starting from various initial configurations. At different stages of the decay, snapshots of the magnetic fields at the equator were taken to yield background field profiles for the stability analysis. The main result is that the Hall instability may really occur in neutron star crusts. Characteristic growth times are in the order of \lesssim 10^4 ... 10^6 yrs depending on cooling age and background field strength. The influence of the equation of state and of the initial field configuration is discussed.

description: In the present work we approximate an ultrarelativistic jet by a homogeneous beam of null matter with finite width. Then, we study the influence of this beam over the space-time metric in the framework of higher-derivative gravity. We find an exact shock wave solution of the quadratic gravity field equations and compare it with the solution to Einstein's gravity. We show that the effect of higher-curvature gravity becomes negligible at large distances from the beam axis. We also observe that only the Ricci-squared term contribute to modify the Einstein's gravity prediction. Furthermore, we note that this higher-curvature term contribute to regularize the discontinuities associated to the solution to Einstein's general relativity.

description: Although studies suggest that air pollution is linked to perinatal outcomes, the geographic characterization of exposure to pollution differs between the studies. Thus, we compared neighborhood and county-level measures of air pollution exposure, while examining the association between particulate matter less than 2.5 micrometers in aerodynamic diameter (PM2.5) and birth weight among full-term births in California in 2000. Our analysis was limited to two populations of 8,579 non-Hispanic white and 8,114 Hispanic mothers who were married, between 20 and 30 years of age, completed at least a high school education, and gave birth for the first time to reduce the effects of demographic variability. Measurements from the nearest monitor, average and distance-weighted average of monitors within a five-mile radius from each mother’s residence (defined as neighborhood metrics) and the mean of monitors within each mother’s county of residence were considered. PM2.5 measurements, provided by the California Air Resources Board, were calculated to correspond to each mother’s nine-month gestation period. Although metrics within the five-mile radii and the county were highly correlated (r2 = 0.78), the county-level metric provided a stronger association between PM2.5 and birth weight (beta = -4.04, 95% confidence interval = -6.71, -1.37) than the metric for the average of all monitors within five-miles (beta = -1.38, 95% confidence interval = -3.36, 0.60) among non-Hispanic white mothers; similar results were observed among the Hispanic sample of mothers. Consequently, inferences from studies using different definitions of air pollution exposure may not be comparable.

description: As a key technology for future wireless networks, massive multiple-input multiple-output (MIMO) can significantly improve the energy efficiency (EE) and spectral efficiency (SE), and the performance is highly dependant on the degree of the available channel state information (CSI). While most existing works on massive MIMO focused on the case where the instantaneous CSI at the transmitter (CSIT) is available, it is usually not an easy task to obtain precise instantaneous CSIT. In this paper, we investigate EE-SE tradeoff in single-cell massive MIMO downlink transmission with statistical CSIT. To this end, we aim to optimize the system resource efficiency (RE), which is capable of striking an EE-SE balance. We first figure out a closed-form solution for the eigenvectors of the optimal transmit covariance matrices of different user terminals, which indicates that beam domain is in favor of performing RE optimal transmission in massive MIMO downlink. Based on this insight, the RE optimization precoding design is reduced to a real-valued power allocation problem. Exploiting the techniques of sequential optimization and random matrix theory, we further propose a low-complexity suboptimal two-layer water-filling-structured power allocation algorithm. Numerical results illustrate the effectiveness and near-optimal performance of the proposed statistical CSI aided RE optimization approach.

description: Galaxy clusters are a promising probe of late-time structure growth, but constraints on cosmology from cluster abundances are currently limited by systematics in their inferred masses. One unmitigated systematic effect in weak-lensing mass inference is ignoring the presence of baryons and treating the entire cluster as a dark matter halo. In this work we present a new flexible model for cluster densities that captures both the baryonic and dark matter profiles, a new general technique for calculating the lensing signal of an arbitrary density profile, and a methodology for stacking those lensing signal to appropriately model stacked weak-lensing measurements of galaxy cluster catalogues. We test this model on 1400 simulated clusters. Similarly to previous studies, we find that a dark matter-only model overestimates the average mass by $7.5\%$, but including our baryonic term reduces that to $0.7\%$. Additionally, to mitigate the computational complexity of our model, we construct an emulator (surrogate model) which accurately interpolates our model for parameter inference, while being much faster to use than the raw model. We also provide an open-source software framework for our model and emulator, called maszcal, which will serve as a platform for continued efforts to improve these mass-calibration techniques. In this work, we detail our model, the construction of the emulator, and the tests which we used to validate that our model does mitigate bias. Lastly, we describe tests of the emulator's accuracy

description: Many current curricula, in going beyond traditional goals, increasingly foster creativity in science classrooms, declaring creativity a core skill of the 21st century. For enhancing creativity in science classrooms, the subject Arts is considered to offer a potential way from STEM (Science, Technology, Engineering, Mathematics) to STEAM (STEM with Arts)). The Horizont-2020 project Creations prepared more than 100 creativity-enhancing STEAM modules based on the 5E instructional model. STEM subjects were mathematics, biology, physics, chemistry or technology, and often interdisciplinary for different school and class levels between the ages of nine and nineteen. All modules provided a social environment fostering creativity where students imagine, explore, experiment, test, manipulate, and speculate. Exemplarily, five modules including physics, math, and biology, were selected, for monitoring motivation and creativity. The first was measured on the level of career-motivation and self-efficacy, the latter focused on two sub-constructs: active cognition such as idea processing (Act), and a mental state of creative immersion (Flow). Subjects were a sample of 995 students (9–18 years). In summary, no gender impact or age effect appeared in any of the monitored variables. Participation intervened with Self-Efficacy and Act, while Career Motivation or Flow did not. Act as a cognitive variable associated with creativity might be more sensitive to changes, whereas Flow as a parameter measuring a state of mind related to emotion appears more stable. Path analysis supported the role of creativity for Career-Motivation by promoting Self-Efficacy. Conclusions for appropriate educational settings to foster STEAM environments are discussed.

description: We have performed low-temperature STM measurements on single-wall carbon nanotubes that are freely suspended over a trench. The nanotubes were grown by CVD on a Pt substrate with predefined trenches etched into it. Atomic resolution was obtained on the freestanding portions of the nanotubes. Spatially resolved spectroscopy on the suspended portion of both metallic and semiconducting nanotubes was also achieved, showing a Coulomb-staircase behavior superimposed on the local density of states. The spacing of the Coulomb blockade peaks changed with tip position reflecting a changing tip-tube capacitance.

An investment in return : supporting aboriginal learners in the public school system
Creators: name: Kemp, Doris Beverly
Publisher: name: The University of British Columbia
Year: 2014

description: British Columbia's education system has failed and continues to fail BC's Aboriginal students. This situation continues to be exacerbated as more and more Aboriginal families move away from reserves to urban centres. This paper first examines data from both the BC Ministry of Education's 2007 report titled, "How Are We Doing?" and independent sources which clearly indicate how poorly Aboriginal students are faring in the public school system in comparison to their non-Aboriginal peers. The paper then provides an historical overview of how residential schools, in their policy to assimilate Aboriginal students, contributed to the children's loss of language, culture, and a sense of identity. Aboriginal students today continue to struggle in a mainstream system that some Aboriginal researchers and educators refer to as a system of cognitive imperialism. The paper concludes with a review of the research which suggest changes that need to occur for Aboriginal children to experience the same success in the Canadian education system as their non-Aboriginal peers.
Comments on "Type II migration strikes back -- An old paradigm for planet migration in discs" by Scardoni et al

description: In the conventional view of type II migration, a giant planet migrates inward in the viscous velocity of the accretion disc in the so-call disc-dominate case. Recent hydrodynamic simulations, however, showed that planets migrate with velocities much faster than the viscous one in massive discs. Such fast migration cannot be explained by the conventional picture. Scardoni et al. (2020) has recently argued this new picture. By carrying out similar hydrodynamic simulations, they found that the migration velocity slows down with time and eventually reaches the prediction by the conventional theory. They interpreted the fast migration as an initial transient one and concluded that the conventional type II migration is realised after the transient phase. We show that the migration velocities obtained by Scardoni et al. (2020) are consistent with the previous simulations even in the transient phase that they proposed. We also find that the transient fast migration proposed by Scardoni et al. (2020) is well described by a new model of Kanagawa et al. (2018). The new model can appropriately describe significant inward migration during the initial transient phase that Scardoni et al. (2020) termed. Hence, we conclude that the time-variation of the transient migration velocity is due to the changes of the orbital radius of the planet and its background surface density during the migration.

title: Role of Thy-1 Glycoprotein in Neurite Outgrowth
Creators: name: Jani, Harsha
Publisher: name: The Open University
Year: 1998

description: In the peripheral nervous system (PNS), neurons regenerate axons following injury and reinnervate their target tissue. The substrate along which these axons extend is of critical importance. Mammalian central nervous system (CNS) neurons, normally unable to regenerate, can do so if given a permissive substrate. Adult axons will regenerate on embryonic CNS tissue and embryonic axons can grow in adult CNS environment but generally adult axons do not regenerate on adult glia. There are inhibitory molecules in the mature CNS environment that regulate growth. In this study I have examined the mature astrocyte-adult axon paradigm.

 Thy-1, a glycoprotein consisting of 110 amino acids is present on mature axons. When transfected into neuroblastoma cell line NG1 15/401L, it inhibits neurite outgrowth on a monolayer of mature astrocytes. I have used primary sensory neurons derived from Thy-1 knockout mice to study the inhibitory effect of Thy-1. I have modified the original method for dissociating dorsal root ganglion cells from adult mice resulting in a population of DRG neurons that grow on average six times longer at 24 hours than other reported measurements. Using an image analysis system for measuring total neurite outgrowth, I have shown that Thy-1 does not prevent but significantly restricts neurite outgrowth over astrocytes. Preliminary experiments on embryonic DRG cells suggests that at a stage in development when Thy-1 is not present on neurons there is no difference in neurite outgrowth between Thy-1 positive and Thy-1 negative DRG cells. A growth restrictive role for Thy-1 is thus indicated. To fully understand the role of the axon-astrocyte interplay I have developed a three-dimensional in vitro system to study the extent to which Thy-1 is involved in this system.

description: We consider a braneworld inflation model driven by the dynamics of a scalar field living in the 5-dimensional bulk, the so-called ``bulk inflaton model'', and investigate the geometry in the bulk and large scale cosmological perturbations on the brane. The bulk gravitational effects on the brane are described by a projection of the 5-dimensional Weyl tensor, which we denote by $E_{μν}$. Focusing on a tachionic potential model, we take a perturbative approach in the anti-de Sitter (AdS$_5$) background with a single de Sitter brane. We first formulate the evolution equations for $E_{μν}$ in the bulk. Next, applying them to the case of a spatially homogeneous brane, we obtain two different integral expressions for $E_{μν}$. One of them reduces to the expression obtained previously when evaluated on the brane. The other is a new expression that may be useful for analyzing the bulk geometry. Then we consider superhorizon scale cosmological perturbations and evaluate the bulk effects onto the brane. In the limit $H^2\ell^2\ll1$, where $H$ is the Hubble parameter on the brane and $\ell$ is the bulk curvature radius, we find that the effective theory on the brane is identical to the 4-dimensional Einstein-scalar theory with a simple rescaling of the potential even under the presence of inhomogeneities. % atleast on super-Hubble horizon scales. In particular, it is found that the anticipated non-trivial bulk effect due to the spatially anisotropic part of $E_{μν}$ may appear only at %second order in the low energy expansion, i.e., at $O(H^4\ell^4)$.

description: Recently, we introduced the "Newman-Penrose map," a novel correspondence between a certain class of solutions of Einstein's equations and self-dual solutions of the vacuum Maxwell equations, which we showed was closely related to the classical double copy. Here, we give an alternative definition of this correspondence in terms of quantities that are defined naturally on twistor space, and a shear-free null geodesic congruence on Minkowski space whose twistorial character is articulated by the Kerr theorem. The advantage of this reformulation is that it is purely geometrical in nature, being manifestly invariant under both spacetime diffeomorphisms and projective transformations on twistor space. While the original formulation of the map may be more convenient for most explicit calculations, the twistorial formulation we present here may be of greater theoretical utility.

title: Unveiling Stakeholder Perspectives on Privacy in the Metaverse: Case Study of a German Car Company

description: Companies have turned their attention to becoming part of the metaverse, a persistent, multi-user, three-dimensional environment characterized by the fusion of virtual and physical elements. While the metaverse offers new ways to create value, related software and hardware components require massive amounts of user data, which can raise privacy concerns. In addition, privacy regulation is in its infancy, creating uncertainty about how to operate in a compliant manner. Building on the multi-stakeholder privacy framework, we explored the privacy stakeholders’ (user, management, policymakers) perspectives on the metaverse, analyzed their relationships, and identified measures to align their interests within a single case study of a German car company. The contribution is twofold. First, we demonstrate the importance of involving privacy stakeholders in the design of products and services in new online environments. Second, we propose privacy measures to reconcile the stakeholders’ interests in the metaverse, providing implications for managers and policymakers.
title: The Nature of Infant Mortality in Norwich and the Effect of Illegitimate Death
Creators: name: Coleman, Helen Jane
Publisher: name: The Open University
Year: 1998

description: In this report a hitherto unexplored source reveals the nature of infant death in one District of Norwich. The classic urban pattern of summer diarrhoeal death is an obvious feature. However, in this overwhelmingly artisan suburb the children of skilled workers stood a greater risk of death then their poorer neighbours. Yet it was illegitimate infants who fared the worse. The peculiar phenomenon of illegitimate mortality follows a distinct pattern set apart from the legitimate model. The inflationary effect of illegitimate death outweighed even diarrhoea in serving to keep infant mortality levels in excess of the national average.

description: The baryonic potential in the framework of the SU(3) random vortex world-surface model is evaluated for a variety of static color source geometries. For comparison, carefully taking into consideration the string tension anisotropy engendered by the hypercubic lattice description, also the Delta and Y law predictions for the baryonic potential are given. Only the Y law predictions are consistent with the baryonic potentials measured.

Enhancement of the stability of genetic switches by overlapping upstream regulatory domains

Year: 2003

description: We study genetic switches formed from pairs of mutually repressing operons. The switch stability is characterised by a well defined lifetime which grows sub-exponentially with the number of copies of the most-expressed transcription factor, in the regime accessible by our numerical simulations. The stability can be markedly enhanced by a suitable choice of overlap between the upstream regulatory domains. Our results suggest that robustness against biochemical noise can provide a selection pressure that drives operons, that regulate each other, together in the course of evolution.

description: We demonstrate a high-flux and low transverse temperature atomic beam of ytterbium by applying two-dimensional cooling using the ${}^1\mathrm{S}_0\text{-}{}^3\mathrm{P}_1$ intercombination transition to the cold atomic beam produced by the dipolar-allowed ${}^1\mathrm{S}_0\text{-}{}^1\mathrm{P}_1$ transition. The optimized transverse temperature of $11 \pm 9\,\mathrm{μK}$ and an atomic flux of $(7.5 \pm 1.0) \times 10^8\,\mathrm{atoms/s}$ are obtained for the atomic beam whose longitudinal velocity is $30\,\mathrm{m/s}$. The transverse temperature is maintained below $23\,\mathrm{μK}$, while the flux is above $6.5 \times 10^8\,\mathrm{atoms/s}$ in the longitudinal velocity range of $22 - 30\,\mathrm{m/s}$. We also discuss the feasibility of further narrowing the transverse momentum width to less than the recoil momentum using the momentum-selective optical transition between the ground state and the long-lived metastable state. The transverse momentum width of our atomic beam, which is narrower than 5.7 times the recoil momentum, is a good starting point for the proposed method.

description: Purpose: To advance research in the field of machine learning for MR image reconstruction with an open challenge. Methods: We provided participants with a dataset of raw k-space data from 1,594 consecutive clinical exams of the knee. The goal of the challenge was to reconstruct images from these data. In order to strike a balance between realistic data and a shallow learning curve for those not already familiar with MR image reconstruction, we ran multiple tracks for multi-coil and single-coil data. We performed a two-stage evaluation based on quantitative image metrics followed by evaluation by a panel of radiologists. The challenge ran from June to December of 2019. Results: We received a total of 33 challenge submissions. All participants chose to submit results from supervised machine learning approaches. Conclusion: The challenge led to new developments in machine learning for image reconstruction, provided insight into the current state of the art in the field, and highlighted remaining hurdles for clinical adoption.
