description: Does the impact of environmental regulation differ by plant vintage and technology? We answer this question using annual Census Bureau information on 116 pulp and paper mills’ vintage, technology, productivity, and pollution abatement operating costs for 1979-1990. We find a significant negative relationship between pollution abatement costs and productivity levels. This is due almost entirely to integrated mills (those incorporating a pulping process), where a one standard deviation increase in abatement costs is predicted to reduce productivity by 5.4 percent. Older plants appear to have lower productivity but are less sensitive to abatement costs, perhaps due to 'grandfathering' of regulations. Mills which undergo renovations are also less sensitive to abatement costs, although these vintage and renovation results are not generally significant. We find similar results using a log-linear version of a three input Cobb-Douglas production function in which we include our technology, vintage, and renovation variables. Sample calculations of the impact of pollution abatement on productivity show the importance of allowing for differences based on plant technology. In a model incorporating technology interactions we estimate that total pollution abatement costs reduce productivity levels by an average of 4.7 percent across all the plants. The comparable estimate without technology interactions is 3.3 percent, approximately 30% lower.

description: I describe a subtraction scheme for the next-to-next-to-leading order calculation of single inclusive production at hadron colliders. Such processes include Drell-Yan, W^{+/-}, Z and Higgs Boson production. The key to such a calculation is a treatment of initial state radiation which preserves the production characteristics, such as the rapidity distribution, of the process involved. The method builds upon the Dipole Formalism and, with proper modifications, could be applied to deep inelastic scattering and e^+ e^- annihilation to hadrons.

description: The problem of finding supersymmetric brane configurations in the near-horizon attractor geometry of a Calabi-Yau black hole with magnetic-electric charges (p^I,q_I) is considered. Half-BPS configurations, which are static for some choice of global AdS2 coordinate, are found for wrapped brane configurations with essentially any four-dimensional charges (u^I,v_I). Half-BPS multibrane configurations can also be found for any collection of wrapped branes provided they all have the same sign for the symplectic inner product p^Iv_I-u^Iq_I of their charges with the black hole charges. This contrasts with the Minkowski problem for which a mutually preserved supersymmetry requires alignment of all the charge vectors. The radial position of the branes in global AdS2 is determined by the phase of their central charge.

It is shown that under cathodic polarization the hydrogen insertion into vanadium oxide from an electrolyte occurs. Metal-insulator transition in amorphous HxVO2 is found to be preserved up to high concentration (x ~ 1.5) of hydrogen. Memory switching with the N-type negative differential resistance, associated with the H+ ionic transfer, is observed in "V/hydrated amorphous vanadium oxide/Au" sandwich structures.

description: Boolean functions on the space $F_{2}^m$ are not only important in the theory of error-correcting codes, but also in cryptography, where they occur in private key systems. In these two cases, the nonlinearity of these function is a main concept. In this article, I show that the spectral amplitude of boolean functions, which is linked to their nonlinearity, is of the order of $2^{m/2}\sqrt{m}$ in mean, whereas its range is bounded by $2^{m/2}$ and $2^m$. Moreover I examine a conjecture of Patterson and Wiedemann saying that the minimum of this spectral amplitude is as close as desired to $2^{m/2}$. I also study a weaker conjecture about the moments of order 4 of their Fourier transform. This article is inspired by works of Salem, Zygmund, Kahane and others about the related problem of real polynomials with random coefficients.

description: In this letter, we develop a Newtonian approach to the collapse of galaxy fluctuations of scalar field dark matter under initial conditions inferred from simple assumptions. The full relativistic system, the so called Einstein-Klein-Gordon, is reduced to the Schrödinger-Newton one in the weak field limit. The scaling symmetries of the SN equations are exploited to track the non-linear collapse of single scalar matter fluctuations. The results can be applied to both real and complex scalar fields.

description: Under current trends, municipal demand for water in Oregon's Willamette River Basin will double by 2050. Municipalities will have to develop new sources of water, in competition with agricultural and other established uses, as well as increased demand for water to support ecological values. Municipalities can, to a limited extent, turn to their currently dormant water rights, but executing these rights will displace other currently established uses of water or diminish flows for fish and wildlife. Recent listings of salmon and other fish under the Endangered Species Act greatly diminish the acceptability of making water-use decisions without accounting for their potential impacts on water quantity and quality throughout the basin. This paper adopts a basin-wide perspective to analyze the need for new development of new sources of municipal water in the basin, and the impact of increased municipal water demand on water resource management in the basin as a whole. The analysis employs a computer model that simulates the regulation of water rights across the basin. We develop scenarios for future demand and supply of water, and use the computer model to determine the resulting allocation of water across water rights in the basin. Results indicate that the state's three largest urban areas have adequate water resources, but many smaller municipalities will have to develop new sources. The analysis here indicates that eliminating summer releases from storage in the basin's federal reservoirs would not affect water availability at current municipal points of diversion.

description: Starting from the previously constructed effective supergravity theory below the scale of U(1) breaking in orbifold compactifications of the weakly coupled heterotic string, we study the effective theory below the scale of supersymmetry breaking by gaugino and matter condensation in a hidden sector. Issues we address include vacuum stability, soft supersymmetry-breaking masses in the observable sector, and the masses of the various moduli fields, including those associated with flat directions at the U(1)-breaking scale, and of their fermionic superpartners. The consistent treatment of U(1) breaking together with condensation yields qualitatively new results.

description: We investigate the large-scale inhomogeneities of the hydrogen ionizing radiation field in the Universe at redshift z=3. Using a raytracing algorithm, we simulate a model in which quasars are the dominant sources of radiation. We make use of large scale N-body simulations of a LambdaCDM universe, and include such effects as finite quasar lifetimes and output on the lightcone, which affects the shape of quasar light echoes. We create Lya forest spectra that would be generated in the presence of such a fluctuating radiation field, finding that the power spectrum of the Lya forest can be suppressed by as much as 15 % for modes with k=0.05-1 Mpc/h. This relatively small effect may have consequences for high precision measurements of the Lya power spectrum on larger scales than have yet been published. We also investigate another radiation field probe, the cross-correlation of quasar positions and the Lya forest. For both quasar lifetimes which we simulate (10^7 yr and 10^8 yr), we expect to see a strong decrease in the Lya absorption close to other quasars (the ``foreground'' proximity effect). We then use data from the Sloan Digital Sky Survey First Data Release to make an observational determination of this statistic. We find no sign of our predicted lack of absorption, but instead increased absorption close to quasars. If the bursts of radiation from quasars last on average < 10^6 yr, then we would not expect to be able to see the foreground effect. However, the strength of the absorption itself seems to be indicative of rare objects, and hence much longer total times of emission per quasar. Variability of quasars in bursts with timescales > 10^4yr and < 10^6 yr could reconcile these two facts.

description: We review studies of vortical motion and the resulting global polarization of $Λ$ and $\barΛ$ hyperons in heavy-ion collisions, in particular, within 3FD model. 3FD predictions for the global midrapidity polarization in the FAIR-NICA energy range are presented. The 3FD simulations indicate that energy dependence of the observed global polarization of hyperons in the midrapidity region is a consequence of the decrease of the vorticity in the central region with the collision energy rise because of pushing out the vorticity field into the fragmentation regions. At high collision energies this pushing-out results in a peculiar vortical structure consisting of two vortex rings: one ring in the target fragmentation region and another one in the projectile fragmentation region with matter rotation being opposite in these two rings.

description: Ascertaining the core-collapse supernova mechanism is a complex, and yet unsolved, problem dependent on the interaction of general relativity, hydrodynamics, neutrino transport, neutrino-matter interactions, and nuclear equations of state and reaction kinetics. Ab initio modeling of core-collapse supernovae and their nucleosynthetic outcomes requires care in the coupling and approximations of the physical components. We have built our multi-physics CHIMERA code for supernova modeling in 1-, 2-, and 3-D, using ray-by-ray neutrino transport, approximate general relativity, and detailed neutrino and nuclear physics. We discuss some early results from our current series of exploding 2D simulations and our work to perform computationally tractable simulations in 3D using the "Yin-Yang" grid.

description: High-mass X-ray binaries (HMXBs) are exceptional astrophysical laboratories that offer a rare glimpse into the physical processes that govern accretion on compact objects, massive-star winds, and stellar evolution. In a subset of the HMXBs, the compact objects accrete matter solely from winds of massive donor stars. These so-called wind-fed HMXBs are divided in persistent HMXBs and supergiant fast X-ray transients (SFXTs) according to their X-ray properties. While it has been suggested that this dichotomy depends on the characteristics of stellar winds, they have been poorly studied. With this investigation, we aim to remedy this situation by systematically analyzing donor stars of wind-fed HMXBs that are observable in the UV, concentrating on those with neutron star (NS) companions. We obtained Swift X-ray data, HST UV spectra, and additional optical spectra for all our targets. Our multi-wavelength approach allows us to provide stellar and wind parameters for six donor stars (four wind-fed systems and two OBe X-ray binaries). The wind properties are in line with the predictions of the line-driven wind theory. Three of the donor stars are in an advanced evolutionary stage, while for some of the stars, the abundance pattern indicates that processed material might have been accreted. When passing by the NS in its tight orbit, the donor star wind has not yet reached its terminal velocity but it is still significantly slower; its speed is comparable with the orbital velocity of the NS companion. There are no systematic differences between the two types of wind-fed HMXBs (persistent versus transients) with respect to the donor stars. For the SFXTs in our sample, the orbital eccentricity is decisive for their transient X-ray nature. Based on the orbital parameters and the further evolution of the donor stars, the investigated HMXBs will presumably form Thorne-Żytkow objects in the future.

Moreover, an approach based on River Formation Dynamics scheme is introduced to analyze the optimization problem for traffic congestion control and a scheme to extract real time information through Internet of Things is presented for superior efficiency and productivity.

description: With the aim of connecting the compositions of stars and planets, we present the abundances of carbon and oxygen, as well as iron and nickel, for the transiting exoplanet host star XO-2N and its wide-separation binary companion XO-2S. Stellar parameters are derived from high-resolution, high-signal-to-noise spectra, and the two stars are found to be similar in their Teff, log g, iron ([Fe/H]), nickel ([Ni/H]) abundances. Their carbon ([C/H]) and oxygen ([O/H]) abundances also overlap within errors, although XO-2N may be slightly more C-rich and O-rich than XO-2S. The C/O ratios of both stars (~0.60+/-0.20) may also be somewhat larger than solar (C/O~0.50). The XO-2 system has a transiting hot Jupiter orbiting one binary component but not the other, allowing us to probe the potential effects planet formation might have on the host star composition. Additionally, with multiple observations of its atmosphere the transiting exoplanet XO-2b lends itself to compositional analysis, which can be compared to the natal chemical environment established by our binary star elemental abundances. This work sets the stage for determining how similar/different exoplanet and host star compositions are, and the implications for planet formation, by discussing the C/O ratio measurements in the unique environment of a visual binary system with one star hosting a transiting hot Jupiter.

Quantum Foam, Gravity and Gravitational Waves

subject: FOS: Physical sciences

description: The new information-theoretic Process Physics has shown that space is a quantum foam system with gravity being, in effect, an inhomogeneous in-flow of the quantum foam into matter. The theory predicts that absolute motion with respect to this system should be observable, and it is shown here that absolute motion has been detected in at least seven experiments. As well this experimental data also reveals the existence of a gravitational wave phenomena associated with the in-flow. It is shown that Galilean Relativity and Special Relativity are in fact compatible, contrary to current beliefs: absolute motion actually causes the special relativity effects. The new theory of gravity passes all the tests of the previous Newtonian and General Relativity theories, but in addition resolves the numerous gravitational anomalies such as the spiral galaxy `dark matter' effect, the absence of `dark matter' in elliptical galaxies, the inconsistencies in measuring G, the borehole g anomaly, and others. It is shown that Newtonian gravity is deeply flawed, because the solar system from which it was developed has too high a spherical symmetry to have revealed key aspects of the phenomena of gravity, and that General Relativity inherited these flaws. The data are revealing that space has structure, and so indicates for the first time evidence of quantum space and quantum gravity effects.

description: This paper examines whether a firm's allocation of production across its plants responds to the environmental regulation faced by those plants, as measured by differences in stringency across states. We also test whether sensitivity to regulation differs based on differences across firms in compliance behavior and/or differences across states in industry importance and concentration. We use Census data for the paper and oil industries to measure the share of each state in each firm's production during the 1967-1992 period. We use several measures of state environmental stringency and test for interactions between regulatory stringency and three factors: the firm's overall compliance rate, a Herfindahl index of industry concentration in the state, and the industry’s share in the state economy. We find significant results for the paper industry: firms allocate smaller production shares to states with stricter regulations. This impact is concentrated among firms with low compliance rates, suggesting that low compliance rates are due to high compliance costs, not low compliance benefits. The interactions between stringency and industry characteristics are less often significant, but suggest that the paper industry is more affected by regulation where it is larger or more concentrated. Our results are weaker for the oil industry, reflecting either less opportunity to shift production across states or a greater impact of environmental regulation on paper mills.
title: Cosmopolitan provincialities : music and exposition culture in liberal Italy

description: At the end of the 19th century, Italy was a young nation-state struggling with imperial aspirations and internal social and economic divides. This political and identity crisis was reflected also in the Italian music production, losing its prevalence in theaters all over the peninsula in favor of foreign, more modern works. Nonetheless, many towns even outside the major cities of Milan and Turin strived to contribute to the glory of the newly born nation-state, both with their industrial production and with culture. In the musical realm, impresarios, patrons, and critics looked at young composers and old repertoires to restore Italy’s renown as a land rich in music. Great expositions of arts and industry represent an excellent viewpoint to observe the interaction between music practices and the quest for a new Italian identity. A global phenomenon appearing in all imperial capitals over the course of the 19th century, expositions became very popular also in Italy, where they took place several times on different scales, following the initiative of local authorities. This study analyses the music pavilions and music activities organized in three such events: the Mostra Internazionale di Musica in Bolgona (1888), the Esposizione Nazionale Italiana in Palermo (1891–92), and the Esposizione Italo-Americana in Genoa (1892). Reconstructing the origin of these events, analyzing the practices they proposed, and questioning their effectiveness with regard to their success with the public, it is clear that expositions became normative models raising preoccupation and anxiety for the hosting communities, but constituted also opportunities for the exploitation and reevaluation of opera, symphonic music, chamber music, military music, and folkloric traditions. From the comparison between all these practices, a lively portrait emerges where music professionals and amateurs equally contributed to shaping the musical image of fin-de-siècle Italy.

description: We investigate the Neel temperature of Sr2CuO3 as a function of the site dilution at the Cu (S=1/2) sites with Pd (S=0), utilizing the muon spin relaxation (muSR) technique. The Neel temperature, which is Tn=5.4K for the undoped system, becomes significantly reduced for less than one percent of doping Pd, giving a support for the previous proposal for the good one-dimensionality. The Pd concentration dependence of the Neel temperature is compared with a recent theoretical study (S. Eggert, I. Affleck and M.D.P. Horton, Phys. Rev. Lett. 89, 47202 (2002)) of weakly coupled one-dimensional antiferromagnetic chains of S=1/2 spins, and a quantitative agreement is found. The inhomogeneity of the ordered moment sizes is characterized by the muSR time spectra. We propose a model that the ordered moment size recovers away from the dopant S=0 sites with a recovery length of ξ= 150-200 sites. The origin of the finite recovery length ξfor the gapless S=1/2 antiferromagnetic chain is compared to the estimate based on the effective staggered magnetic field from the neighboring chains.

description: Using the FLUIDICS (Fluid Dynamics in Space) experiment in the International Space Station, turbulence of capillary waves at the air-water interface is experimentally investigated in weightlessness. Capillary waves are excited in a spherical container partially filled with water and undergoing sinusoidal or random oscillations. The fluctuations of the interface, recorded with two capacitive probes are analyzed by means of the frequency power spectrum of wave elevation. For high enough forcing amplitudes, we report power-law spectra with exponents close to the prediction of weak wave turbulence theory. However, in this experiment the free-surface steepness is not small compared to 1 and thus the investigated regimes correspond to strongly nonlinear wave turbulence.

description: In this paper we estimate the price premium associated with organic baby food by applying a hedonic model to price and characteristic data for baby food products collected in two cities: Raleigh/Durham, North Carolina and San Jose, California. We use price per jar of baby food as the dependent variable and control for a number of baby food characteristics (e.g., brand, type, and stage) as well as store characteristics (e.g. type of retail establishment). We find the price premium associated with the organic characteristic to be approximately 12 cents per jar. To the extent this premium reflects parents’ preferences regarding the reduction of their baby’s exposure to pesticide residues, our results could be paired up with risk data to estimate the value of the health benefits associated with reduced exposure.

description: We construct sphaleron solutions in Weinberg-Salam theory, which possess only discrete symmetries. Related to rational maps of degree N, these sphalerons carry baryon number Q_B=N/2. The energy density of these sphalerons reflects their discrete symmetries. We present an N=3 sphaleron with tetrahedral energy density, an N=4 sphaleron with cubic energy density, and an N=5 sphaleron with octahedral energy density.

description: Strong local opposition to the construction of solid waste landfills has become commonplace and the siting of landfills in the United States is time consuming and expensive. To ease the siting process, host compensation in exchange for permission to construct a landfill has become popular. The value and nature of host compensation varies dramatically across communities, but the reasons for this variation are relatively unexplored. We construct a national data set consisting of host fees paid by the 104 largest privately owned solid waste landfills in 1996, along with the characteristics of the landfills and the host communities. Our findings suggest that he direct participation of citizens in host fee negotiations, the community knowledge stemming from having hosted a prior landfill, and the presence of state mandates for minimum host compensation all lead to much greater amounts of host compensation. We find that the bargaining position of the landfill developer is less important, in terms of the magnitude of the effect. However we do find evidence that firms with deeper pockets are more likely to pay higher host fees. We find limited evidence that a community’s race and income level matter after accounting for factors that directly reflect citizen involvement. The analysis also indicates that landfills that accept risky wastes, such as contaminated soil or sludge, and problematic wastes, such as tires pay higher host fees.
Critical analysis of quantitative-qualitative research models into the effect of instructional and transformational leadership on student achievement
Creators: name: Tello, Esther
Publisher: name: The University of British Columbia

description: The purpose of this study is to examine a body of mixed methods (qualitative and quantitative) research on how instructional and transformational leaders' behaviours affect student achievement. Current political demands on the role of the school principal and increased emphasis on accountability place students' academic achievement at the top of school reform agendas and add weight to the role of the school principal (Gentilucci & Muto, 2007; VSB Leadership District Review Team, 2008; Ministry of Education BC Mandate for the School System, 2008, British Columbia Educational Council, 2008). I critically analyze the latest research findings with the purpose of offering practical insights and contributions to policy makers, researchers and educational leaders to model future courses of action in educational administration and accountability. The two research studies considered in this review were conducted by Alig- Mielcarek (2003) and Leithwood, Jantzi, and McElheron-Hopkins (2006). Alig- Mielcarek (2003) in the state of Ohio, United States, carried out a study on instructional leadership and student achievement in 146 schools. Similarly, Leithwood, Jantzi, and McElheron-Hopkins (2006) conducted a study in Ontario, Canada, over five years, on transformational leadership and student achievement in 100 schools. Two layers of analysis are used in this review. The first layer of analysis conceptualizes the leadership role according to De Maeyer et al.' s (2007) theoretical framework: instructional and transformational leadership models. The objective of this layer of analysis is to see to what extent the conceptual role of the principal matches the variables considered in the methodology of each study. The second layer of analysis examines the conceptual methodologies used by the researchers according to Hallinger and Heck's (1988) theoretical perspective on administrative leadership. I interpret the multilevel nature of the path analyses utilized by the researchers and the variables they linked directly or indirectly to student achievement. The objective of the second layer of analysis is to examine the extent of the multilevel approach employed in their path analysis and the validity of the findings. This study concludes that both Alig-Mielcarek's (2003) study and Leithwodd et al.'s (2006) study contribute to a better understanding of the path models that can be used to study educational leadership and student achievement. However, there are some threats to the validity of both studies; careful attention must be paid to the numbers of variables at each level and to gathering the most accurate data available. Neither study's leadership frameworks appears sufficient for effective school leadership. A combination of diverse frameworks is recommended to meet current educational demands.

description: Controlling the strain level in nanowire heterostructures is critical for obtaining coherent interfaces of high crystalline quality and for the setting of functional properties such as photon emission, carrier mobility or piezoelectricity. In a nanowire axial heterostructure featuring a sharp interface, strain is set by the materials lattice mismatch and the nanowire radius. Here, we show that introducing a graded interface in nanowire heterostructures offers an additional parameter to control strain. For a given interface length and lattice mismatch, we first derive theoretically the maximum nanowire radius below which coherent growth is possible. We validate these findings by growing and characterizing various In(Ga)As/GaAs nanowire heterostructures with graded interfaces. Furthermore, we perform a complete chemical and structural characterization of the interface by combining energy-dispersive X-ray spectroscopy and high resolution transmission electron microscopy. In the case of coherent growth, we directly observe that the mismatch strain relaxes elastically on the side walls of the nanowire around the interface area, while the core of the nanowire remains partially strained. Moreover, our experimental data show good agreement with finite element calculations. This analysis confirms in particular that mechanical strain is largely reduced by interface grading. Overall, our work extends the parameter space for the design of nanowire heterostructures, thus opening new opportunities for nanowire optoelectronics.

description: We have performed for the first time a complete $r$-process mass sensitivity study in the $N=82$ region. We take into account how an uncertainty in a single nuclear mass propagates to influence important quantities of neighboring nuclei, including Q-values and reaction rates. We demonstrate that nuclear mass uncertainties of $\pm0.5$ MeV in the $N=82$ region result in up to an order of magnitude local change in $r$-process abundance predictions. We identify key nuclei in the study whose mass has a substantial impact on final $r$-process abundances and could be measured at future radioactive beam facilities.

description: We show that the natural map from the mapping class groups of surfaces to the automorphism groups of free groups, induces an infinite loop map on the classifying spaces of the stable groups after plus construction. The proof uses automorphisms of free groups with boundaries which play the role of mapping class groups of surfaces with several boundary components.

description: We investigate core-collapse supernova (CCSN) nucleosynthesis in polar axisymmetric simulations using the multidimensional radiation hydrodynamics code CHIMERA. Computational costs have traditionally constrained the evolution of the nuclear composition in CCSN models to, at best, a 14-species $α$-network. Such a simplified network limits the ability to accurately evolve detailed composition, neutronization and the nuclear energy generation rate. Lagrangian tracer particles are commonly used to extend the nuclear network evolution by incorporating more realistic networks in post-processing nucleosynthesis calculations. Limitations such as poor spatial resolution of the tracer particles, estimation of the expansion timescales, and determination of the "mass-cut" at the end of the simulation impose uncertainties inherent to this approach. We present a detailed analysis of the impact of these uncertainties on post-processing nucleosynthesis calculations and implications for future models.

The classroom writing centre : how and why teachers should implement a classroom writing centre
Creators: name: Scott, Sarah
Publisher: name: The University of British Columbia
Year: 2014

description: The purpose of this paper is to examine the theory and research surrounding classroom writing centres and to provide suggestions as to how primary teachers can develop classroom writing centres that provide opportunities to enhance early literacy development. This paper looks at the importance of time management, physical space materials and the provision of authentic literacy experiences when designing a classroom writing centre using a workshop approach. A review of the literature includes a look at emergent literacy perspectives and impact that emergent literacy study has had on literacy practices in the classroom and the ways in which writing, drawing and talking are intrinsically linked in literacy instruction. The literature further considers the role that the writing process and studies surrounding this topic have impacted current literacy instruction practices and the literacy development of young children. In order to connect theory to practice, I have prepared a workshop for teachers at my school that highlights the importance of including a writing centre in the classroom, the theory this idea and the success that I personally have had with the writing centre. The paper concludes with implications for early primary teachers looking to enhance their classroom writing programs.
