description: Using density functional theory we have performed theoretical investigations of the electronic properties of a free-standing one-dimensional organometallic vanadium-benzene wire. This system represents the limiting case of multi-decker V_n(C6H6)_{n+1} clusters which can be synthesized. We predict that the ground state of the wire is a 100% spin-polarized ferromagnet (half-metal). Its density of states is metallic at the Fermi energy for the minority electrons and shows a semiconductor gap for the majority electrons. We found that the half-metallic behavior is conserved up to 12%, longitudinal elongation of the wire. However, under further stretching, the system exhibits a transition to a high-spin ferromagnetic state that is accompanied by an abrupt jump of the magnetic moment and a gain of exchange energy.

description: The population of young, non-recycled pulsars with spin down energies Edot >10^35 erg/s is sampled predominantly at gamma-ray and radio wavelengths. A total of 137 such pulsars are known, with partial overlap between the sources detectable in radio and gamma-rays. We use a very small set of assumptions in an attempt to test whether the observed pulsar sample can be explained by a single underlying population of neutron stars. For radio emission we assume a canonical conal beam with a fixed emission height of 300~km across all spin periods and a luminosity law which depends on Edot^{0.25}. For gamma-ray emission we assume the outer-gap model and a luminosity law which depends on Edot^{0.5}. We synthesise a population of fast-spinning pulsars with a birth rate of one per 100 years. We find that this simple model can reproduce most characteristics of the observed population with two caveats. The first is a deficit of gamma-ray pulsars at the highest Edot which we surmise to be an observational selection effect due to the difficulties of finding gamma-ray pulsars in the presence of glitches without prior knowledge from radio frequencies. The second is a deficit of radio pulsars with interpulse emission, which may be related to radio emission physics. We discuss the implications of these findings.

description: It is now believed that the universe is composed of a small amount of the normal luminous matter, a substantial amount of matter (Cold Dark Matter: CDM) which is non-luminous and a large amount of smooth energy (Dark Energy: DE). Both CDM and DE seem to require ideas beyond the standard model of particle interactions. In this work, we argue that CDM and DE can arise entirely from the standard principles of strong interaction physics out of the same mechanism.

description: Active galactic nuclei (AGNs) are key for understanding the coevolution of galaxies and supermassive black holes (SMBHs). AGN activity is thought to affect the properties of their host galaxies, via a process called "AGN feedback", which drives the co-evolution. From a parent sample of 1151 z < 1 type-1 quasars from the Sloan Digital Sky Survey quasar catalog, we detected host galaxies of 862 of them in the high-quality grizy images of the Subaru Hyper Suprime-Cam (HSC) survey. The unprecedented combination of the survey area and depth allows us to perform a statistical analysis of the quasar host galaxies, with small sample variance. We fit the radial image profile of each quasar as a linear combination of the point spread function and the Sersic function, decomposing the images into the quasar nucleus and the host galaxy components. We found that the host galaxies are massive, with stellar mass Mstar > 10^(10) Msun, and are mainly located on the green valley. This trend is consistent with a scenario in which star formation of the host galaxies is suppressed by AGN feedback, that is, AGN activity may be responsible for the transition of these galaxies from the blue cloud to the red sequence. We also investigated the SMBH mass to stellar mass relation of the z < 1 quasars, and found a consistent slope with the local relation, while the SMBHs may be slightly undermassive. However, the above results are subject to our sample selection, which biases against host galaxies with low masses and/or large quasar-to-host flux ratios.

description: We present a fast Monte-Carlo algorithm for simulating epitaxial surface growth, based on the continuous-time Monte-Carlo algorithm of Bortz, Kalos and Lebowitz. When simulating realistic growth regimes, much computational time is consumed by the relatively fast dynamics of the adatoms. Continuum and continuum-discrete hybrid methods have been developed to approach this issue; however in many situations, the density of adatoms is too low to efficiently and accurately simulate as a continuum. To solve the problem of fast adatom dynamics, we allow adatoms to take larger steps, effectively reducing the number of transitions required. We achieve nearly a factor of ten speed up, for growth at moderate temperatures and large D/F.

Interferometric Visibility and Closure Phase of Microlensing Events with Finite Source Size

description: Interferometers from the ground and space will be able to resolve the two images in a microlensing event. This will at least partially lift the inherent degeneracy between physical parameters in microlensing events. To increase the signal-to-noise ratio, intrinsically bright events with large magnifications will be preferentially selected as targets. These events may be influenced by finite source size effects both photometrically and astrometrically. Using observed finite source size events as examples, we show that the fringe visibility can be affected by 5% - 10%, and the closure phase by a few degrees: readily detectable by ground and space interferometers. Such detections will offer unique information about the lens-source trajectory relative to the baseline of the interferometers. Combined with photometric finite source size effects, interferometry offers a way to measure the angular sizes of the source and the Einstein radius accurately. Limb-darkening changes the visibility by a small amount compared with a source with uniform surface brightness, marginally detectable with ground-based instruments. We discuss the implications of our results for the plans to make interferometric observations of future microlensing events.

description: The recent reform of the Common Agricultural Policy in Europe has had significant implications for Leadership in the UK. The move from economic support for food production, to support for environmental deliveries has created the need for a new culture where leaders are very conscious that alliances leading to added political strength and financial viability are now likely to be far more effective than charismatic leadership from the front and top of organizations. The paper will go on to develop the theme of leadership strategy by drawing on many of the writings of the leadership academics and gather experts opinions and ideas regarding farmer's culture and its implications for leadership. The paper concludes that the problem for the agricultural industry at the moment is that so many changes are occurring that a consistent future is very hard to define. Therefore, agricultural leaders now have to articulate the new policies as they evolve on an almost daily basis. The need is for clear and informed leaders who engage widely across society.
Investigation of phosphatidylinositol-3-kinase (PI3K) and extracellular signal-regulated kinase 1/2 (ERK1/2) activation
Creators: name: Chiu, Doris Diane
Publisher: name: University of British Columbia
Year: 2009

description: There have been conflicting studies in the past several years regarding the relationship between PI3K activation and its potential role in ERK1/2 activation. Some studies indicate that PI3K activation is required for ERK1/2 activation, yet other studies suggest that there is no relationship between the two. In this thesis we hypothesize that PI3K activation is not required for ERK1/2 activation. To investigate this hypothesis we used several cell systems, including a human, hemopoietic cell line, TF-1, and murine, hemopoietic cell lines FDC-P1 and BAF-3 cells. Also, we used a human embryonic kidney cell line, HEK 293. With the use of pharmacological inhibitors of PI3K, LY294002 and wortmannin it was concluded that ERK1/2 activation does not require PI3K activation. We also addressed the question of what role PI3K plays in the regulation of protein synthesis. However, in order to test this, we first investigated whether our cell systems contained the important components of the translational protein machinery including, elF-4E and 4E-BPs. Afterwards, we tested the effects of using various inhibitors, including the PI3K inhibitors LY294002, wortmannin, MEK1/2 inhibitors, U0I26 and the FRAP/mTOR inhibitor rapamycin. From our preliminary experiments we determined that 4E-BP1 is present in TF-1 cells and 4E-BP2 is present in FDC-P1, MC-9 and TF-1 cells. Furthermore, elF-4E is present in all three cell systems. With the use of the inhibitors, we observed that LY294002 inhibits the phosphorylation of 4E-BP1, U0126 did not block the phosphorylation of 4E-BP1 and rapamycin partially blocked the phosphorylation of 4E-BP1. Surprisingly, wortmannin did not block the phosphorylation of 4EBP1. Due to the preliminary nature of the results, more experiments are needed to fully understand the role that PI3K may play in the regulation of protein translation.

description: We estimate the reaction mechanisms for the photoproduction of the Theta^+(1540) resonance on the nucleon, through K and K^* Regge exchanges. We compare the size of the cross sections for the gamma n -> K^- Theta^+ and gamma p -> K^0 bar Theta^+ reactions, and investigate their sensitivity to the spin-parity assignments J^P = 1/2^\pm, 3/2^\pm for the Theta^+ resonance. The model allows to estimate the cross sections corresponding with a given upper bound on the width of the Theta^+. Within this model, the cross sections on the neutron are found to be around a factor 5 larger than the ones on the proton, due to the presence of charged K exchange for the reaction on a neutron target. Furthermore, the photon asymmetry is found to display a pronounced sensitivity to the parity of the Theta^+, making it a very promising observable to help determining the quantum numbers of the Theta^+ resonance.

description: It is now an undisputable fact that rural women farmers produce more than half of all the food grown in Nigeria. They are mainly responsibility for providing food for their families as they plant, harvest and fish, gather fuel wood, fetch water, cook as well as process and sell foodstuffs. This paper describes them as invisible actors in the hunger drama because though they feed the nation, they have little or no access to factors of production that boost productivity such as extension services. Indeed, while the dominance of women in rural areas are evident, policy makers, planners and extension officials often behave as if women did not exist, as if the situation and needs of all farmers were the same, whether men or women. Agricultural extension is one of the main tools for increasing agricultural productivity because it bridges the gap between technical knowledge and farmers practices. Thus, it is fundamental to rural women's ability to feed the nation in a sustainable way. The main objective of this paper therefore, is to highlight some evidences to support the contention that rural farmers in general and women in particular are not being well served by existing extension systems in Nigeria. The findings are from a pilot survey of women farmers in Abuja, Nigeria. The results suggest that failure to reach women farmers is part of an overall problem related to lack of support and resources. With about one or two extension workers being assigned to work with as many as 1000 farm families, the need for policy review is obvious. The paper recommends that gender targeting of extension services is crucial to the fight against hunger in rural Nigeria and the ability to feed the nation in a sustainable way. The paper is organized in five sections.

description: In the context of spontaneous wave function collapse models, we investigate the properties of the Continuous Spontaneous Localization (CSL) collapse rate for rigid bodies. By exploiting the Euler-Maclaurin formula, we show that for standard matter the rate for a continuous mass distribution accurately reproduces the exact rate (i.e. the one for a point-like distribution). We compare the exact rate with previous estimates in the literature and we asses their validity. We find that the reduction rate displays a peculiar mass difference effect, which we investigate and describe in detail. We show that the recently proposed layering effect is a consequence of the mass difference effect.

The legislation operates through "Orders" and the paper reports the obligations of employers and sharemilkers under the most recent (2001) Order. Statistics on lower order sharemilkers are presented. A case study shows the nature of the returns to lower order sharemilking. The paper concludes with comments on the likely future of lower order sharemilking in New Zealand.
Free Cash Flow Is At Least as Important as Profit in Assessing a Farm Firm

description: This paper suggests that most small agribusinesses can use a short cut to see how their firms are doing financially. The short cut requires that they calculate and follow (1) profit and (2) free cash flow. Both are defined and clarified. The reason for this short cut is that most small firm owners do not do enough financial analysis and that this simple and quick study may encourage them. The paper does not encourage the substitution of these two numbers for a proper analysis. They are useful but more of a bait to land the full course.

description: We investigate a spectroscopic sample of 48 early-type (E+S0) galaxies in the rich cluster Abell 2390 (z=0.23) and 48 E+S0 galaxies from a previously published survey of Abell 2218 (z=0.18). The A2390 spectra are based on Multi Object Spectroscopy with MOSCA at the Calar Alto 3.5-m, complemented by ground-based and HST F555W and F814W observations. Our investigation spans a broad range in luminosity (-20.5>M_r>-23.0) and a wide FOV of 1.5x1.5 Mpc^2. Since the A2218 and A2390 samples are very similar, we can combine them and analyse a total of 96 E+S0 galaxies at z~0.2. We construct the Faber-Jackson relation (FJR) for all E+S0s and detect a modest luminosity evolution. The average offset from the local FJR in Gunn r-band is (DeltaM_r)=0.32+-0.22^m. Less-massive galaxies show a trend for a larger evolution than more-massive galaxies. HST/WFPC2 surface brightness profile fits were used to derive structural parameters. For 34 E+S0 galaxies which enter the Fundamental Plane (FP) we deduce a mild evolution in Gunn r with a zero-point offset of 0.10+-0.06, corresponding to 0.31+-0.18^m. Elliptical and lenticular galaxies are uniformly distributed along the FP with a similar scatter of 0.1 dex. We find little evidence for differences between the populations of ellipticals and S0s. Lenticulars induce on average a larger evolution of 0.44+-0.18^m than ellipticals with 0.02+-0.21^m. The M/L ratios at z=0.2 are offset by (Deltalog(M/L_r))=-0.12+-0.06 dex compared to those of Coma. Our results can be reconciled with a passive evolution of the stellar populations and a high formation redshift for the bulk of the stars in E+S0 galaxies. However, our findings are also consistent with the hierarchical formation picture for rich clusters. [abridged]

description: Electromagnetism (E&M) is often challenging for students enrolled in introductory college-level physics courses. Compared to mechanics, the mathematics of E&M is more sophisticated and the representations are more abstract. Furthermore, students may lack productive intuitions they had with force and motion. In this article, we explore the mathematization of electric charge. Specifically, we explore how difficulties with positive and negative signs can arise for learners who approach integers primarily as positions on a number line.

description: Information on liquid jet stream flow is crucial in many real world applications. In a large number of cases, these flows fall directly onto free surfaces (e.g. pools), creating a splash with accompanying splashing sounds. The sound produced is supplied by energy interactions between the liquid jet stream and the passive free surface. In this investigation, we collect the sound of a water jet of varying flowrate falling into a pool of water, and use this sound to predict the flowrate and flowrate trajectory involved. Two approaches are employed: one uses machine-learning models trained using audio features extracted from the collected sound to predict the flowrate (and subsequently the flowrate trajectory). In contrast, the second method directly uses acoustic parameters related to the spectral energy of the liquid-liquid interaction to estimate the flowrate trajectory. The actual flowrate, however, is determined directly using a gravimetric method: tracking the change in mass of the pooling liquid over time. We show here that the two methods agree well with the actual flowrate and offer comparable performance in accurately predicting the flowrate trajectory, and accordingly offer insights for potential real-life applications using sound.

description: To unveil the logic of cell from a level of chemical reaction dynamics, we need to clarify how ensemble of chemicals can autonomously produce the set of chemical, without assuming a specific external control echanism. A cell consists of a huge number of chemical species that catalyze each other. Often the number of each molecule species is not so large, and accordingly the number fluctuations in each molecule speciescan be large. In the amidst of such diversity and large fluctuations, how can a cell make recursive production? On the other hand, a cell can change its state to evolve to a different type over a longer time span. How are reproduction and evolution compatible? We address these questions, based on several model studies with catalytic reaction network. In the present survey paper, we first formulate basic questions on the recursiveness and evolvability of a cell, and then state the standpoint of our research to answer the questions, that is termed as 'constructive biology'. Based on this standpoint, we present general strategy of modeling a cell as a chemical reaction network.

description: Recent research in marketing has focused on cross-category variation in the market share of private label products, while recent work in the economics and industrial organization literature has focused on the determinants of firm price setting behavior. In this paper, the authors develop a framework for estimating market share and price reaction equations simultaneously in an attempt to understand the nature of competitive interaction in the market for private label and branded grocery products. Empirical findings support the author's premise that consumer response to price and promotion decisions (demand) and the factors influencing firm pricing behavior (supply) jointly determine observed market prices and market shares. More specifically, the authors find a positive relationship between share and price on the supply side reflecting market power influences and a traditional negative relationship between share and price on the demand side. Finally, when Oligopolistic interdependence is measured by specifying brand share, brand Herfindahl, and local retail market structure measures, results indicate the branded price is higher in markets dominated be national brands.

"Real war and no make-believe" : the spectacle of the Mexican Revolution on screen
Creators: name: Clark, Joseph E. J.
Publisher: name: University of British Columbia
Year: 2009

description: In 1914, the Mutual Film Company signed a contract with the Mexican General Pancho Villa for the exclusive rights to his war. Under the agreement Villa was given $25,000 and a percentage of the profits in exchange for allowing Mutual cameramen to follow his southern advance on the federal forces of Victoriano Huerta. In addition to using the Mexican footage as part of their Mutual Weekly newsreel series, the film company released a feature film telling the life story of Villa himself. In all of these films, Mutual combined so-called authentic documentary footage with dramatic reenactments and even entirely fictional elements. Despite this deliberate construction of the Mexican Revolution on screen, the film's realism was its selling point. Mutual used its contract with Villa and a host of other public relations strategies to convince audiences that its films were absolutely authentic. But while reality was the pitch it was never more than a means to an end. Realism was a crucial part of Mutual's attempts to transform the Mexican Revolution into a cinematic spectacle they could sell to US audiences. By looking at these films through the intertextual web of advertisements, news reports and even fictional representations we will see how Mutual, helped by Villa himself, attempted to use stereotypes of Mexico and Mexican-ness to create the reality effect. Moreover, informed by the ideas of Guy Debord and others, we will see how reality itself was commodified and used to create the spectacle of the Mexican Revolution.

description: We investigate the luminosity dependence of quasar clustering, inspired by numerical simulations of galaxy mergers that incorporate black hole growth. These simulations have motivated a new interpretation of the quasar luminosity function. In this picture, the bright end of the quasar luminosity function consists of quasars radiating nearly at their peak luminosities, while the faint end consists mainly of very similar sources, but at dimmer phases in their evolution. We combine this model with the statistics of dark matter halos that host quasar activity. We find that, since bright and faint quasars are mostly similar sources seen in different evolutionary stages, a broad range in quasar luminosities corresponds to only a narrow range in the masses of quasar host halos. On average, bright and faint quasars reside in similar host halos. Consequently, we argue that quasar clustering should depend only weakly on luminosity. This prediction is in qualitative agreement with recent measurements of the luminosity dependence of the quasar correlation function (Croom et al. 2005) and the galaxy-quasar cross-correlation function (Adelberger & Steidel 2005). Future precision clustering measurements from SDSS and 2dF, spanning a large range in luminosity, should provide a strong test of our model.

description: The analysis of GPS trajectories is a well-studied problem in Urban Computing and has been used to track people. Analyzing people mobility and identifying the transportation mode used by them is essential for cities that want to reduce traffic jams and travel time between their points, thus helping to improve the quality of life of citizens. The trajectory data of a moving object is represented by a discrete collection of points through time, i.e., a time series. Regarding its interdisciplinary and broad scope of real-world applications, it is evident the need of extracting knowledge from time series data. Mining this type of data, however, faces several complexities due to its unique properties. Different representations of data may overcome this. In this work, we propose the use of a feature retained from the Ordinal Pattern Transition Graph, called the probability of self-transition for transportation mode classification. The proposed feature presents better accuracy results than Permutation Entropy and Statistical Complexity, even when these two are combined. This is the first work, to the best of our knowledge, that uses Information Theory quantifiers to transportation mode classification, showing that it is a feasible approach to this kind of problem.

description: The outer atmosphere of the M supergiant Betelgeuse is puzzling. Published observations of different kinds have shed light on different aspects of the atmosphere, but no unified picture has emerged. They have shown, for example, evidence of a water envelope (MOLsphere) that in some studies is found to be optically thick in the mid-infrared. In this paper, we present high-resolution, mid-infrared spectra of Betelgeuse recorded with the TEXES spectrograph. The spectra clearly show absorption features of water vapor and OH. We show that a spectrum based on a spherical, hydrostatic model photosphere with T_eff = 3600 K, an effective temperature often assumed for Betelgeuse, fails to model the observed lines. Furthermore, we show that published MOLspheres scenarios are unable to explain our data. However, we are able to model the observed spectrum reasonably well by adopting a cooler outer photospheric structure corresponding to T_mod = 3250 K. The success of this model may indicate the observed mid-infrared lines are formed in cool photospheric surface regions. Given the uncertainties of the temperature structure and the likely presence of inhomogeneities, we cannot rule out the possibility that our spectrum could be mostly photospheric, albeit non-classical. Our data put new, strong constraints on atmospheric models of Betelgeuse and we conclude that continued investigation requires consideration of non-classical model photospheres as well as possible effects of a MOLsphere. We show that the mid-infrared water-vapor features have great diagnostic value for the environments of K and M (super-) giant star atmospheres.

description: We estimate the effects of new brands on market competition and consumer welfare in the U.S. processed cheese market. We find that an observed increase in consumer welfare was attributable mainly to an increase in the number of brands in the sample market, while the price effect, which measures welfare change caused by adding new brands to existing brands, decreased welfare as the prices of the existing brands increased in a large portion of sample markets. The price increase was most pronounced among the introducer's existing brands.

description: Paul Erdos asked how frequently the ternary expansion of 2^n omits the digit 2. He conjectured this happens only for finitely many values of n. We generalize this question to consider iterates of two discrete dynamical systems. The first is over the real numbers, and considers the integer part of lambda 2^n for a real input lambda. The second is over the 3-adic integers, and considers the sequence lambda 2^n for a 3-adic integer input lambda. We show that the number of input values that have infinitely many iterates omitting the digit 2 in their ternary expansion is small in a suitable sense. For each nonzero input we give an asymptotic upper bound on the number of the first k iterates that omit the digit 2, as k goes to infinity. We also study auxiliary problems concerning the Hausdorff dimension of intersections of multiplicative translates of 3-adic Cantor sets.

description: In this paper we specify a price determination model which can test both the traditional positive interbrand price - share hypothesis and the negative intrabrand relationship predicted by residual demand analysis. We evaluate this relationship empirically using three-dimensional panel data from the catsup industry. We find support for both hypothesized relationships, and conclude that market power exists in this industry. Further, we conclude that the results depend critically on the characteristics of the data set to be analyzed.

description: In early 2002, the Royal Ahold subsidiary, Stop & Shop Supermarkets, offered to purchase the Big V supermarket chain, which was in bankruptcy court after three successive, unsuccessful leveraged buyouts over the past ten years. At a later date, Pathmark Supermarkets joined the offer to purchase. Big V was Wakefern Food Corporation's largest member. The acquisition was a horizontal merger in at least three local markets, Newburgh NJ, Poughkeepsie NY, and Trenton NJ. This research was conducted for the Wakefern Food Corporation who provided much of the underlying data and information. We presented this report to the Bureau of Competition, Federal Trade Commission in March 2002 and to the New Jersey and New York Attorney Generals, Antitrust Section in April 2002. Thereafter, the Federal Trade Commission issued a second request in its merger review, and the bankruptcy judge ruled against the Stop & Shop/Pathmark offer. Big V subsequently was purchased by Wakefern and remains in the Shop Rite supermarket cooperative system.

description: Pressure-temperature phase diagram of the organic Mott insulator $κ$-(ET)$_2$Cu$_2$(CN)$_3$, a model system of the spin liquid on triangular lattice, has been investigated by $^1$H NMR and resistivity measurements. The spin-liquid phase is persistent before the Mott transition to the metal or superconducting phase under pressure. At the Mott transition, the spin fluctuations are rapidly suppressed and the Fermi-liquid features are observed in the temperature dependence of the spin-lattice relaxation rate and resistivity. The characteristic curvature of Mott boundary in the phase diagram highlights a crucial effect of the spin frustration on the Mott transition.

Calculations of Electric Capacitance in Carbon and BN Nanotubes, and Zigzag Nanographite (BN, BCN) Ribbons

description: Electronic states in nanographite ribbons with zigzag edges are studied using the extended Hubbard model with nearest neighbor Coulomb interactions. The electronic states with the opposite electric charges separated along both edges are analogous as nanocondensers. Therefore, electric capacitance, defined using a relation of polarizability, is calculated to examine nano-functionalities. We find that the behavior of the capacitance is widely different depending on whether the system is in the magnetic or charge polarized phases. In the magnetic phase, the capacitance is dominated by the presence of the edge states while the ribbon width is small. As the ribbon becomes wider, the capacitance remains with large magnitudes as the system develops into metallic zigzag nanotubes. It is proportional to the inverse of the width, when the system corresponds to the semiconducting nanotubes and the system is in the charge polarized phase also. The latter behavior could be understood by the presence of an energy gap for charge excitations. In the BN (BCN) nanotubes and ribbons, the electronic structure is always like of semiconductors. The calculated capacitance is inversely proportional to the distance between the positive and negative electrodes.

description: In an undulant universe, cosmic expansion is characterized by alternating periods of acceleration and deceleration. We examine cosmologies in which the dark-energy equation of state varies periodically with the number of e-foldings of the scale factor of the universe, and use observations to constrain the frequency of oscillation. We find a tension between a forceful response to the cosmic coincidence problem and the standard treatment of structure formation.

description: This article tests the Protection for Sale (PFS) model using detailed data from U.S. food processing industries from 1978 to 1992 under alternative import demand specifications. All empirical results support the PFS model predictions and previous empirical work qualitatively. Although welfare weights are very sensitive to import demand specification, a surprising result is that we obtain weights between 2.6 and 3.6 for domestic welfare using import slopes or elasticities derived from domestic demand and supply functions. In contrast, results based on import slopes or elasticities from directly specified import demands (including the Armington model) yield the usual, unrealistically large estimates for the domestic welfare weight. We contend that the latter empirical paradox arises mainly because the explanatory variables tend to be extremely large for industries with low import ratios and/or low estimated elasticities or slopes resulting from relatively volatile import prices. The results with derived import parameters point to a much stronger role of campaign contributions within the PFS model than previously found. They also suggest that the commonly-used Armington estimates may not be appropriate for estimating the PFS model.
