description: We reveal how to exploit joint spatial-electromagnetic duality symmetries to obtain invariant scattering properties (including extinction, scattering, absorption) of self-dual scattering systems for incident waves of arbitrary polarizations. The electromagnetic duality ensures the helicity preservation along all scattering directions, and thus intrinsically eliminates the interferences between the two scattering channels originating from the circularly polarized components of incident waves. This absence of interference directly secures invariant scattering properties for all polarizations located on the same latitude circle of the Poincaré sphere, which are characterized by polarization ellipses of the same eccentricity and handedness. Further incorporations of mirror and/or inversion symmetries would lead to such invariance throughout the whole Poincaré sphere, guaranteeing invariant scattering properties for all polarizations. Simultaneous exploitations of composite symmetries of different natures render an extra dimension of freedom for scattering manipulations, offering new insights for both fundamental explorations and optical device engineering related to symmetry dictated light-matter interactions.

description: The relationship between the design and functionality of molecular networks is now a key issue in biology. Comparison of regulatory networks performing similar tasks can give insights into how network architecture is constrained by the functions it directs. We here discuss methods of network comparison based on network architecture and signaling logic. Introducing local and global signaling scores for the difference between two networks we quantify similarities between evolutionary closely and distantly related bacteriophages. Despite the large evolutionary separation between phage $λ$ and 186 their networks are found to be similar when difference is measured in terms of global signaling. We finally discuss how network alignment can be used to to pinpoint protein similarities viewed from the network perspective.

description: EBEX is a balloon-borne polarimeter designed to measure the intensity and polarization of the cosmic microwave background radiation. The measurements would probe the inflationary epoch that took place shortly after the big bang and would significantly improve constraints on the values of several cosmological parameters. EBEX is unique in its broad frequency coverage and in its ability to provide critical information about the level of polarized Galactic foregrounds which will be necessary for all future CMB polarization experiments. EBEX consists of a 1.5 m Dragone-type telescope that provides a resolution of less than 8 arcminutes over four focal planes each of 4 degree diffraction limited field of view at frequencies up to 450 GHz. The experiment is designed to accommodate 330 transition edge bolometric detectors per focal plane, for a total of up to 1320 detectors. EBEX will operate with frequency bands centered at 150, 250, 350, and 450 GHz. Polarimetry is achieved with a rotating achromatic half-wave plate. EBEX is currently in the design and construction phase, and first light is scheduled for 2008.

description: Let (G, +) be an abelian group. A subset of G is sumfree if it contains no elements x, y, z such that x +y = z. We extend this concept by introducing the Schur degree of a subset of G, where Schur degree 1 corresponds to sumfree. The classical inequality S(n) $\le$ R n (3) -- 2, between the Schur number S(n) and the Ramsey number R n (3) = R(3,. .. , 3), is shown to remain valid in a wider context, involving the Schur degree of certain subsets of G. Recursive upper bounds are known for R n (3) but not for S(n) so far. We formulate a conjecture which, if true, would fill this gap. Indeed, our study of the Schur degree leads us to conjecture S(n) $\le$ n(S(n -- 1) + 1) for all n $\ge$ 2. If true, it would yield substantially better upper bounds on the Schur numbers, e.g. S(6) $\le$ 966 conjecturally, whereas all is known so far is 536 $\le$ S(6) $\le$ 1836.
Berry Phase Effects on Dynamics of Quasiparticles in a Superfluid with a Vortex

description: We study quasiparticle dynamics in a Bose-Einstein condensate with a vortex by following the center of mass motion of a Bogoliubov wavepacket, and find important Berry phase effects due to the background flow. We show that Berry phase invalidates the usual canonical relation between the mechanical momentum and position variables, leading to important modifications of quasiparticle statistics and thermodynamic properties of the condensates. Applying these results to a vortex in an infinite uniform superfluid, we find that the total transverse force acting on the vortex is proportional to the superfluid density. We propose an experimental setup to directly observe Berry phase effects through measuring local thermal atoms momentum distribution around a vortex.

description: This study attempted to investigate a sample of both parents' and college freshmens' attitudes toward sex education, and the content and timing of sex education in the Tidewater schools. Two Likert-type scales each containing ten statements were administered in order to survey attitudes. A statistically significant difference was found in scores on the attitude toward content and timing of sex education scale between parents and college freshmen. Parents demonstrated a more favorable attitude toward sex education as an integral component of the overall educational curriculum. The majority of parents indicated support for including important aspects such as reproduction and indicated that they may be introduced as early as age five.

The results were not statistically significant on attitudes toward sex education in the schools scale between parents and college freshmen. Both of these groups demonstrated high scores, indicating support of sex education in the Tidewater schools.

description: Spectral splitters, as well as solar concentrators, are commonly designed and optimized using numerical methods. Here, we present an experimental method to spectrally split and concentrate broadband light (420 nm - 875 nm) via wavefront shaping. We manage to spatially control white light using a phase-only spatial light modulator. As a result, we are able to split and concentrate three frequency bands, namely red (560 nm - 875 nm), green (425 nm - 620 nm), and blue (420 nm - 535 nm), to two target spots with a total enhancement factor of 715 %. Despite the significant overlap between the color channels, we obtain spectral splitting ratios as 52 %, 57 %, and 66 % for red, green, and blue channels, respectively. We show that a higher number of adjustable superpixels ensures higher spectral splitting and concentration. We provide the methods to convert an optimized phase pattern into a diffractive optical element that can be fabricated at large scale and low cost. The experimental method that we introduce, for the first time, enables the optimization and design of SpliCons, which is $\sim$ 300 times faster compared to the computational methods.

description: The Magnetic Eden Model (MEM) with ferromagnetic interactions between nearest-neighbor spins is studied in $(d+1)-$dimensional rectangular geometries for $d = 1,2$. In the MEM, magnetic clusters are grown by adding spins at the boundaries of the clusters. The orientation of the added spins depends on both the energetic interaction with already deposited spins and the temperature, through a Boltzmann factor. A numerical Monte Carlo investigation of the MEM has been performed and the results of the simulations have been analyzed using finite-size scaling arguments. As in the case of the Ising model, the MEM in $d = 1 $ is non-critical (only exhibits an ordered phase at $T= 0$). In $d = 2$ the MEM exhibits an order-disorder transition of second-order at a finite temperature. Such transition has been characterized in detail and the relevant critical exponents have been determined. These exponents are in agreement (within error bars) with those of the Ising model in 2 dimensions. Further similarities between both models have been found by evaluating the probability distribution of the order parameter, the magnetization and the susceptibility. Results obtained by means of extensive computer simulations allow us to put forward a conjecture which establishes a nontrivial correspondence between the MEM for the irreversible growth of spins and the equilibrium Ising model. This conjecture is certainly a theoretical challenge and its confirmation will contribute to the development of a framework for the study of irreversible growth processes.

description: The purpose of this paper is to outline the opportunities available to the Canadian retail grocery industry with regard to meat and poultry. The fresh meat and poultry department is one of the largest and fastest growing areas of the grocery store. At the same time, its potential as a point of differentiation and as a merchandising flagship for the retailer remains largely untapped. Furthermore, for the meat and poultry sectors to move forward to higher levels of customer satisfaction and value, the industry requires that the retail sector take a leadership role. It needs to be noted that from a technological and attitudinal perspective, industry processors and producers are now more ready to move forward with retailers than at any time in the past. It is hoped that this paper will help to make retailers aware of the untapped potential and to encourage the rest of the industry to be prepared to move forward with their retail partners.

UV Sensitivity in Supersymmetric Large Extra Dimensions: The Ricci-flat Case

description: We examine the ultraviolet (UV)-sensitive part of the one-loop Casimir energy which is induced when various higher-dimensional supergravities are compactified to 4D on extra dimensions which are Ricci flat, but otherwise arbitrary. We identify the leading dependence on the mass of very massive higher-dimensional modes, as well as the UV divergent part of the contributions of modes which are massless in the higher-dimensional sense (but which consist of a KK tower of massive modes from the 4D perspective), and show how these are constrained by higher-dimensional general covariance. Some of the implications of co-dimension 2 branes are computed in the limit where their tension is small compared with the extra-dimensional Planck scale (but not small compared with the observed dark energy). Our results support the interpretation of supersymmetric large extra dimensions (SLED) in 6 dimensions as a potential solution to the cosmological constant problem (but do not yet completely clinch the case).

Irreversible growth of a binary mixture confined in a thin film geometry with competing walls

description: The irreversible growth of a binary mixture under far-from-equilibrium conditions is studied in three-dimensional confined geometries of size $L_x \times L_y \times L_z$, where $L_z \gg L_x = L_y$ is the growing direction. A competing situation where two opposite surfaces prefer different species of the mixture is analyzed. Due to this antisymmetric condition an interface between the different species develops along the growing direction. Such interface undergoes a localization-delocalization transition that is the precursor of a wetting transition in the thermodynamic limit. Furthermore, the growing interface also undergoes a concave-convex transition in the growth mode. So, the system exhibits a multicritical wetting point where the growing interface is almost flat and the interface between species is essentially localized at the center of the film.

description: SAT research has a long history of source code and binary releases, thanks to competitions organized every year. However, since every cycle of competitions has its own set of rules and an adhoc way of publishing source code and binaries, compiling or even running any solver may be harder than what it seems. Moreover, there has been more than a thousand solvers published so far, some of them released in the early 90's. If the SAT community wants to archive and be able to keep track of all the solvers that made its history, it urgently needs to deploy an important effort. We propose to initiate a community-driven effort to archive and to allow easy compilation and running of all SAT solvers that have been released so far. We rely on the best tools for archiving and building binaries (thanks to Docker, GitHub and Zenodo) and provide a consistent and easy way for this. Thanks to our tool, building (or running) a solver from its source (or from its binary) can be done in one line.

description: We present a scheme to prepare generalized coherent states in a system with two species of Bose-Einstein condensates. First, within the two-mode approximation, we demonstrate that a Schrodinger cat-like can be dynamically generated and, by controlling the Josephson-like coupling strength, the number of coherent states in the superposition can be varied. Later, we analyze numerically the dynamics of the whole system when interspecies collisions are inhibited. Variables such as fractional population, Mandel parameter and variances of annihilation and number operators are used to show that the evolved state is entangled and exhibits sub-Poisson statistics.

description: The impact of axion-like particles (ALPs) on the search of permanent electric dipole moments (EDMs) of molecules, atoms, nuclei and nucleons is systematically investigated. We classify first the full set of CP-violating Jarlskog invariants emerging in the ALP effective field theory (EFT) containing operators up to dimension-5. Then, we evaluate the leading short-distance effects to the EDMs up to two-loop order. The high sensitivity of EDMs to CP-violating ALP interactions is emphasised exploiting both the current and projected experimental sensitivities.

The cyborg-other : Japan’s animated images of sex, gender, and race
Creators: name: Knowles, Alison Michelle
Publisher: name: University of British Columbia
Year: 2009

description: Using a semiotic reading of gender codes and Donna Haraway's cyborg theory, this paper is a study of the image of the cyborg through Japanese animated films and by extension a study of Japan through the cyborg. In such animated films as "Ghost in the Shell" (Oshii Mamoru, 1995), "Battle Angel" (Fukutomi Hiroshi, 1993), and "Neon Genesis Evangelion" (Anno Hideaki, 1996) the cyborg characters present new images of a hybrid cyborg-sexuality, cyborg-gender, and cyborg-race. The cyborg is a being in science fiction, as well as in cutting-edge science and technology, that is a combination of organic and cybernetic. The cyborg destroys the boundary between human and machine, by its very definition, and other boundaries by its use and interpretation. Japan has many images of the cyborg and metal-merged bodies in animated films and comic books. Japanese animated films and comic books show the cyborg's hybridity, as theorized by Haraway and others, in regards to sex, gender, and race. Using the cyborg image as a reflection of Japan, Japan shows hybridity in the same areas.

A metahistory of J. Edgar Hoover
Creators: name: MacIntyre, Jeffrey
Publisher: name: University of British Columbia
Year: 2009

description: J. Edgar Hoover is a nonpareil figure among modern American icons, seemingly both an agent and victim of history. As the Director of the Federal Bureau of Investigation for nearly fifty years (1924-1972), Hoover at once forged a public persona as the nation's foremost crime-fighter and assumed a backstage role as political rainmaker, holding court through eight presidencies. His posthumous celebrity, however, simultaneously dwarfs and compromises this legacy. Longstanding suspicions about Hoover's private life, widely disseminated and accepted in the mid-1990s as transvestism and homosexuality, have accrued the special resonance popular culture reserves for scandal-ridden caricature. How can one begin to account for this sea change in the American public imagination? The posthumous speculations about Hoover suggest a curious and profoundly ambivalent response to a period of American life for which cultural narratives are only now being written—and for which Hoover seems to - have earned a central place. I will look to four narratives which prominently feature J. Edgar Hoover and remark on his influence on the political and cultural climate of his times. Examining literary biography, novel, and film genres will demonstrate representative and popular forms of historical narrative; moreover, their strikingly similar use of emplotment and characterization begs further questions. The thematic of Hoover envisioned by literary, biographic, and cinematic artists can be convincingly sketched as a Left or libertarian Zeitgeist which warns against the frailty of justice, the corruptibility of the powerful, and the tyranny of the state. I intend to argue that each narrative treatment of Hoover establishes an essentially singular, composite text: a metanarrative explaining Hoover's role, particularly in post-war American history, as an archetypal tyrant-fascist and principal symbol for the vagaries of Cold War anxiety. I will address the popular recrudescence of Hoover in light of several related arguments: that cultural memory articulates contemporary national identity; that the vicissitudes of the Cold War in the United States can be described as a movement from a culture of consensus to one of dissent; that present developments in the American ideological disposition follow a similar pattern; and that ideological assent only follows the consensus-creating power of a national jeremiad. The present revisioning of Hoover appears to be such a jeremiad, and hints at the workings of a broader national consciousness intent on re-examining and re-drawing its recent history.
Strategies for implementation of selective dry cow treatment in spring-calving pasture-based dairy production systems

description: There is a requirement to reduce the use of antimicrobials in animal production systems. Blanket dry cow therapy (BDCT) using an antibiotic with or without internal teat seal (ITS) at dry-off has been widely practiced in Irish dairy herds. Infusion of cows without an intramammary infection (IMI) at dry-off with an ITS alone has been identified as an area for potential reduction in antibiotic use; a practice referred to as selective dry cow treatment (SDCT). The overall aim of the research carried out in this thesis was to both evaluate the impact and establish strategies when implementing SDCT without negatively impacting SCC and IMI in low bulk tank SCC (≤200,000 cells/ml) Irish spring-calving pasture-based dairy herds. This encompassed four scientific papers assessing the efficacy of ITS in herds, precisely differentiating between cows with and without IMI in the lead up to dry-off using SCC data and establishing the association between SDCT and herd management strategies. In the first paper a total of 842 cows across 5 herds with a cow?level SCC of <200,000 cells/ml were assigned ITS or antibiotic plus ITS (AB+ITS) at dry-off. Cows treated with ITS alone had significantly higher SCC and higher risk of new IMI in the following lactation compared to those treated with AB+ITS. However, there were significant differences to the efficacy of ITS according to the herd studied. In the second paper, cow-level SCC data of 2,074 cows across 21 herds was evaluated to predict IMI at dry-off. The last test-day SCC was the best predictor of infection at dry-off. The cut-point for last test-day SCC which maximised sensitivity and specificity was 64,975 cells/ml. Using the same data set as Paper 2, Paper 3 showed that when using quarter?level SCC, the cut-point for last test-day SCC which maximised sensitivity and specificity was 61,000 cells/ml for primiparous and 101,000 cells/ml for multiparous cows. In the fourth paper the association between SDCT and herd management practices was explored using data from 2,016 cows across 21 herds. There was a significant interaction between SDCT and milk yield at last test-day; cows with milk yield >15kg and treated with ITS had a higher SCC in the following lactation compared to cows treated with AB+ITS. Regarding management practices, using a California Mastitis Test to detect high SCC quarters and cleaning cubicles twice daily over the dry period were associated with lower SCC in the following lactation. In all studies, Staphylococcus aureus was the predominant pathogen accounting for 87.0% to 92.1% of quarter-level IMI. Overall these findings provide criteria and management practices to guide the identification and selection of cows suitable for ITS at dry-off.
High pT leading hadron suppression in nuclear collisions at sqrt(s_NN) = 20 -- 200 GeV: data versus parton energy loss models

description: Experimental results on high transverse momentum (leading) hadron spectra in nucleus-nucleus collisions in the range sqrt(s_NN) = 20 -- 200 GeV are reviewed with an emphasis on the observed suppression compared to free space production in proton-proton collisions at the corresponding center-of-mass energies. The transverse-momentum and collision-energy (but seemingly not the in-medium path length) dependence of the experimental suppression factors measured in central collisions is consistent with the expectations of final-state non-Abelian parton energy loss in a dense QCD medium.

description: Polaritons, coupled excitations of photons and dipolar matter excitations, can propagate along anisotropic metasurfaces with either hyperbolic or elliptical dispersion. At the transition from hyperbolic to elliptical dispersion (corresponding to a topological transition), various intriguing phenomena are found, such as an enhancement of the photonic density of states, polariton canalization and hyperlensing. Here we investigate theoretically and experimentally the topological transition and the polaritonic coupling of deeply subwavelength elements in a uniaxial infrared-phononic metasurface, a grating of hexagonal boron nitride (hBN) nanoribbons. By hyperspectral infrared nanoimaging, we observe, for the first time, a synthetic transverse optical phonon resonance (that is, the strong collective near-field coupling of the nanoribbons) in the middle of the hBN Reststrahlen band, yielding a topological transition from hyperbolic to elliptical dispersion. We further visualize and characterize the spatial evolution of a deeply subwavelength canalization mode near the transition frequency, which is a collimated polariton that is the basis for hyperlensing and diffraction-less propagation. Our results provide fundamental insights into the role of polaritonic near-field coupling in metasurfaces for creating topological transitions and polariton canalization.

description: The dairy industry in Canada was turned on its ear by the release of the WTO decision last fall that Canada's Special Milk Classes constitute an export subsidy. Dairy processors fear the loss of established export markets. At the same time, the decision threatens the role of supply management authorities as the sole marketers of farmers' milk. Will farmers market milk for export directly to processors? What consequences could renewed marketing board involvement in exports have in the international trade arena? The industry is preparing for conflict as it reorients itself in the international market. That conflict is embedded in proposals made by some of the milk marketing agencies and by some processor members of the National Dairy Council (NDCC). Because of the immediate importance of this case and the issues it spawns, the George Morris Centre is releasing this special report. It addresses the following topics: * The nature of the challenges to the Special Milk Classes scheme * The WTO decision * Implications for the dairy industry * Marketing board's proposal for export pricing reform * NDCC proposal for export pricing reform * Evaluation of the alternatives

description: This study suggests that confidence intervals for WASDE forecasts of corn, soybean, and wheat prices may be improved if they are estimated using an empirical approach. Empirical confidence intervals are calculated following Williams and Goodman's (1971) method and use historical forecast errors to estimate forecast error distributions which is then used to predict confidence limits for future forecast errors. Three procedures for empirical distribution estimation are compared: 1) histogram, 2) changing distribution, 3) fixed distribution. The results suggest that the fixed distribution approach using logistic distribution provided accurate confidence intervals for WASDE corn, soybean, and wheat price forecasts.

description: Stochastic optimization algorithms have become indispensable in modern machine learning. An unresolved foundational question in this area is the difference between with-replacement sampling and without-replacement sampling -- does the latter have superior convergence rate compared to the former? A groundbreaking result of Recht and Ré reduces the problem to a noncommutative analogue of the arithmetic-geometric mean inequality where $n$ positive numbers are replaced by $n$ positive definite matrices. If this inequality holds for all $n$, then without-replacement sampling indeed outperforms with-replacement sampling. The conjectured Recht-Ré inequality has so far only been established for $n = 2$ and a special case of $n = 3$. We will show that the Recht-Ré conjecture is false for general $n$. Our approach relies on the noncommutative Positivstellensatz, which allows us to reduce the conjectured inequality to a semidefinite program and the validity of the conjecture to certain bounds for the optimum values, which we show are false as soon as $n = 5$.

U.S. and Canadian Livestock Prices: Market Integration and Trade Dependence

Livestock Production/Industries

description: Cointegration of Canadian and U.S. livestock prices points to the existence of market integration in the period 1996:1 to 2004:12 even though the trade flows of livestock and beef products were non-existent for many months in 2003 and 2004 (suggesting market segmentation) due to livestock/beef import bans by both countries due to BSE. It was also determined that Canada's trade dependence in livestock and beef is cointegrated with Canadian and U.S. livestock prices. However, as the trade dependence variable is shocked, the effects on Canadian and U.S. prices are opposite although one would expect that in an integrated market the price responses to an exogenous shock would be similar or statistically identical. This result reinforces the case against the use of cointegration in determining presence (or absence) of market integration. Empirical results in this article raise some very difficult questions. Gains from trade are well documented. Yet, once a country is very trade dependent, the prices in it are much more vulnerable to exogenous shocks that reduce the trade flows. Canadian livestock prices plummeted and stayed low following the BSE incident and U.S. (and Japanese) import bans on Canadian livestock and beef. Given the long cycles and high sunk cost in the livestock and beef industry, immediate adjustment (reduction in production) for Canadian producers was difficult and always unlikely. Moreover, the possibility of import bans being lifted in the near future may have further shaped their expectations and prolonged the decisions on herd reduction. In the meanwhile, U.S. prices increased following Canada's trade dependence shock due to BSE and remained above the original long-run equilibrium price.
Two-Scalar Bose-Einstein Condensates: From Stars to Galaxies

description: We study the properties of Bose-Einstein Condensate (BEC) systems consisting of two scalars, focusing on both the case where the BEC is stellar scale as well as the case when it is galactic scale. After studying the stability of such systems and making contact with existing single scalar limits, we undertake a numerical study of the two interacting scalars using Einstein-Klein-Gordon (EKG) equations, including both non-gravitational self-interactions and interactions between the species. We show that the presence of extra scalars and possible interactions between them can leave unique imprints on the BEC system mass profile, especially when the system transitions from being dominated by one scalar to being dominated by the other. At stellar scales (nonlinear regime,) we observe that a repulsive interaction between the two scalars of the type $+ϕ_1^2 ϕ_2^2$ can stabilize the BEC system and support it up to high compactness, a phenomenon only known to exist in the $+ϕ^4$ system. We provide simple analytic understanding of this behavior and point out that it can lead to interesting gravitational wave signals at LIGO-Virgo. At galactic scales, on the other hand, we show that two-scalar BECs can address the scaling problem that arises when one uses ultralight dark matter mass profiles to fit observed galactic core mass profiles. In the end, we construct a particle model of two ultralight scalars with the repulsive $ϕ_1^2 ϕ_2^2$ interaction using collective symmetry breaking. We develop a fast numerical code that utilizes the relaxation method to solve the EKG system, which can be easily generalized to multiple scalars.

description: In this paper, we investigate the ground state properties of a mixture of two species of fermionic atoms in one-dimensional optical lattice, as described by the asymmetric Hubbard model. The quantum phase transition from density wave to phase separation is investigated by studying both the corresponding charge order parameter and quantum entanglement. A rigorous proof that even for the single hole doping case, the density wave is unstable to the phase separation in the infinite U limit, is given. Therefore, our results are quite instructive for both on-going experiments on strongly correlated cold-atomic systems and traditional heavy fermion systems.

The Gluon Spin Asymmetry as a Link to Delta G and Orbital Angular Momentum

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The fundamental program in high energy spin physics focuses on the spin structure of the nucleon. The gluon and orbital angular momentum components of the nucleon spin are virtually unknown. The J_z=1/2 sum rule involves the integrated parton densities and can be used to extract information on the orbital angular momentum and its evolution. To avoid any bias on a model of Delta G, we assume that the gluon asymmetry, A=Delta G/G can be used to extract Delta G over a reasonable kinematic region. Combining the results for Delta G with the evolution equations, we can determine a theoretical expression for the orbital angular momentum and its evolution.

description: USDA livestock production forecasts are evaluated for information across multiple horizons using the direct test developed by Vuchelen and Gutierrez. Forecasts are explicitly tested for rationality (unbiased and efficient) as well as for incremental information out to three quarters ahead. The results suggest that although the forecasts are often not rational, they typically do provide the forecast user with unique information at each horizon. Turkey and milk production forecasts tended to provide the most consistent performance, while beef production forecasts provided little information beyond the two quarter horizon.

description: Federal government funding for public price reporting began in 1914. Since then, most public market reporting for livestock and meat has relied on voluntary participation by market participants. Populist support in 1999 led to passage of the Livestock Mandatory Reporting Act which replaced the decades old voluntary reporting system with a mandatory system for livestock and meat. Questions were raised by policymakers and others in discussions of the Act's renewal as to effectiveness of the mandatory reporting system. This paper draws from available information to assess the Act's effectiveness since its initial implementation. Satisfaction or dissatisfaction with the Act depends on one's expectations for what the Act was to accomplish or problems the Act was argued to address. Mandatory price reporting for many - after a rocky start - has enhanced the transparency and accuracy of reported prices while increasing the amount and timeliness of information in some needed areas.
