description: This article develops a methodology for empirically analyzing vertically strategic interactions in a multi-level supply channel. The model is used to analyze the vertical channel for U.S. butter manufacturing and retailing. Aggregating products to the firm level and using a nonlinear AIDS demand system under alternative strategic pricing assumptions is estimated using full information maximum likelihood (FIML) for seven geographic markets from 1998-2002. The market demand for butter was found to very price elastic. Furthermore, cross price elasticities between private labels and the two large national brands were also very elastic. The selected market structure was one indicating category profit maximization of national brands (separate from private label) at the retail level, Vertical Nash competition in the vertical channel, and Bretrand competition at the manufacturing level. Our results strongly suggest that the retail market for food products is impacted by the underlying vertical structure. The study provides useful measures of imperfect competition in the retail manufacturing sector.

description: The liberalization and restructuring of the seed sector in eastern and southern Africa (ESA) during the past two decades have witnessed a proliferation of private seed companies in the maize seed industry (Hassan et al., 2001; Lemonius, 2005). Although the total number of registered maize seed companies increased from 8 and 11, respectively, in 1997 to 40 each, the quantities of seed marketed barely doubled, increasing from 23,000 and 27,000 tons to 53,000 and 51,000 tons, respectively; an indication that the reforms are insufficient in ensuring efficient functioning of the sector in the two regions. A study involving 117 seed providers, representing 92 percent of all registered maize seed companies in ESA in 2007 identified bottlenecks that have differential impacts on the establishment and operation of a seed company, seed production and processing, seed marketing and demand, and seed policy in the two regions. To promote growth and development of the maize seed industry, it is imperative for a coordinated intervention effort by both public and private sector players to address the various bottlenecks. The collection, processing, dissemination and management of information on varietal release and adaptation remain vital in ensuring success of the coordinated effort.

description: The Council Regulation (EC) 1698/2005 approved on 20th September 2005 was the starting point of the fourth programme of Rural Development Aid for the period 2007-2013. This communitarian programme affects Andalusia, an European region situated in the south of Spain. The authors of this paper have helped in the elaboration of the rural strategy for this region. We would specially like to point out the use of the Prospective Structural Analysis (PSA) methodology as a competent method to analyse the complexity of elements, variables and present interactions in rural zones as well as to understand variables in the present and future situation. Results obtained with the application of the PSA method to a region show the strength of this methodology in order to help the process of reflection about influencing economic and social agents in the analysed area.

description: We present calculations of the spin-averaged pair distribution function $g(r)$ in a homogeneous gas of electrons moving in dimensionality D=3 or D=2 at finite temperature. The model involves the solution of a two-electron scattering problem via an effective potential which embodies many-body effects through a self-consistent Hartree approximation, leading to two-body wave functions to be averaged over a temperature-dependent distribution of relative momentum for electron pairs. We report illustrative numerical results for $g(r)$ in an intermediate-coupling regime and interpret them in terms of changes of short-range order with increasing temperature.

description: The viability of agricultural enterprises is of paramount importance. Their liquidation has harmful effects on broad strata of society. The aim of my research is therefore to analyze the leading causes of liquidation of agricultural enterprises. The research was led on 17 agricultural enterprises. This may help in the prevention and treatment of their insolvency. The research results show that a long-term agricultural production is not sustainable with a low equity capital. For the long-term maintenance it is necessary that the investors establish the enterprise with a capital according to the type of the production. The loan can not replace the entrepreneurs own resources, it is only complementary to it. The owners of agricultural businesses should strive to ensure that the paid-up share capital is kept in the firm, because in case of payment difficulties, this can be an adequate financial provision. Companies with financial problems can avoid liquidation if the crisis is detected in time by the leaders. However, the owners must organize the management of the enterprise so that it should have the necessary technical and economic knowledge. With an appropriate management, and use of means of crisis management, the liquidation of the enterprise can be prevented.

description: The thermal properties of a suspended metallic single-wall carbon nanotube (SWNT) are extracted from its high-bias (I-V) electrical characteristics over the 300-800 K temperature range, achieved by Joule self-heating. The thermal conductance is approximately 2.4 nW/K and the thermal conductivity is nearly 3500 W/m/K at room temperature for a SWNT of length 2.6 um and diameter 1.7 nm. A subtle decrease in thermal conductivity steeper than 1/T is observed at the upper end of the temperature range, which is attributed to second order three-phonon scattering between two acoustic modes and one optical mode. We discuss sources of uncertainty and propose a simple analytical model for the SWNT thermal conductivity including length and temperature dependence.

description: The passage of U.S. laws mandating and subsidizing advanced cellulosic biofuels may spur the development of a commercial cellulosic biofuels industry. However, a cellulosic industry will only develop if the overall economics including government incentives render investment in the sector attractive to private investors. This study compares the profitability of three biofuel production types: grain based ethanol, cellulosic biochemical ethanol, and cellulosic thermochemical biofuels. In order to compare the current profitability of each of the production types, the Biofuels Comparison Model (BCM) was developed. The BCM is a spreadsheet model that estimates the net present value (NPV) for each production type given input and output prices, technical, and financial assumptions. The BCM can be updated to reflect the current profitability through embedded web price links. The study finds that grain, biochemical, and thermochemical production types are all currently unprofitable when subsidies and mandates are ignored. However, the grain based ethanol process is predicted to be the most profitable (lowest loss) compared to the cellulosic biofuels. When the 2008 Farm Bill subsidies are added to the BCM, all three production types are projected to be profitable. With the addition of the different subsidies, the cellulosic biofuels are estimated to have higher NPV’s than grain based ethanol. When compared on an energy equivalent basis, the estimated cost of producing grain ethanol is $114/bbl. crude oil equivalent, biochemical ethanol $141/bbl., and thermochemical gasoline $108/bbl.
The Benefits and Costs of Social Distancing in Rich and Poor Countries

description: Social distancing is the primary policy prescription for combating the COVID-19 pandemic, and has been widely adopted in Europe and North America. We estimate the value of disease avoidance using an epidemiological model that projects the spread of COVID-19 across rich and poor countries. Social distancing measures that "flatten the curve" of the disease to bring demand within the capacity of healthcare systems are predicted to save many lives in high-income countries, such that practically any economic cost is worth bearing. These social distancing policies are estimated to be less effective in poor countries with younger populations less susceptible to COVID-19, and more limited healthcare systems, which were overwhelmed before the pandemic. Moreover, social distancing lowers disease risk by limiting people's economic opportunities. Poorer people are less willing to make those economic sacrifices. They place relatively greater value on their livelihood concerns compared to contracting COVID-19. Not only are the epidemiological and economic benefits of social distancing much smaller in poorer countries, such policies may exact a heavy toll on the poorest and most vulnerable. Workers in the informal sector lack the resources and social protections to isolate themselves and sacrifice economic opportunities until the virus passes. By limiting their ability to earn a living, social distancing can lead to an increase in hunger, deprivation, and related mortality and morbidity. Rather than a blanket adoption of social distancing measures, we advocate for the exploration of alternative harm-reduction strategies, including universal mask adoption and increased hygiene measures.
Zostera marina and Neotrypaea californiensis as indicators of ecosystem integrity in Grice Bay, British Columbia
Creators: name: Carty, Sarah Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: Using indicator species as proxies to assess ecosystem integrity has been identified as a necessary means to develop efficient and effective ways to monitor natural ecosystems. Criteria have been developed to aid in the choice of an indicator species and while there are still limitations, improvements can be made by choosing more than one species and having multiple indices to measure. This study established baseline data on the seagrass, Zostera marina and ghost shrimp, Neotrypaea californiensis for their use as health indicators in Grice Bay, Clayoquot Sound, British Columbia. The widespread distribution and ecological importance of seagrasses and their sensitivity to water quality parameters have led to the use of these plants as biological indicators of water quality. In this study, seagrass biomass, density, size structure, reproductive timing & frequency were quantified as indicator parameters. Physiological indices, for use as early warning signals, were also quantified including sugar & chlorophyll concentrations. Ghost shrimp have not previously been used as an indicator species, however their important role in the food web of Grice Bay as the primary detritivore and as a prey species for juvenile gray whales makes them an important organism to monitor. Indicator qualities of ghost shrimp are those sensitive to water quality, such as density, biomass, population size structure, frequency of reproductive females, size of reproductive females and length of reproductive season.
Reduced Phase Space Quantization and Dirac Observables

description: In her recent work, Dittrich generalized Rovelli's idea of partial observables to construct Dirac observables for constrained systems to the general case of an arbitrary first class constraint algebra with structure functions rather than structure constants. Here we use this framework and propose a new way for how to implement explicitly a reduced phase space quantization of a given system, at least in principle, without the need to compute the gauge equivalence classes. The degree of practicality of this programme depends on the choice of the partial observables involved. The (multi-fingered) time evolution was shown to correspond to an automorphism on the set of Dirac observables so generated and interesting representations of the latter will be those for which a suitable preferred subgroup is realized unitarily. We sketch how such a programme might look like for General Relativity. We also observe that the ideas by Dittrich can be used in order to generate constraints equivalent to those of the Hamiltonian constraints for General Relativity such that they are spatially diffeomorphism invariant. This has the important consequence that one can now quantize the new Hamiltonian constraints on the partially reduced Hilbert space of spatially diffeomorphism invariant states, just as for the recently proposed Master constraint programme.

description: The objective of this paper is to present the teaching note of a case study. The case study outlines the strategic issues facing Excel Cooperative as a result of the rapid expansion of biofuel production capacity in the Midwestern U.S. Excel Cooperative is a mid-sized, ‘local’, farmer-owned cooperative serving farmers in north central Indiana. Excel is composed of four divisions: agronomy, energy, grain, and feed/livestock. With the Excel case, the reader must think strategically about the broad impacts of the biofuel “boom”, apply strategic management tools and decision-making under uncertainty concepts to better understand the impacts, and frame a response. The methodology proposed in the teaching note is composed of a SWOT analysis, scorecarding and heat mapping, scenario analysis, payoff matrix, and decision tree. A SWOT analysis is a useful way to identify the uncertainties. Scorecarding and heat mapping assessment tools can then be used to assess and map the uncertainties, and decide which uncertainties the company should capitalize on and which projects could be pursued to exploit those uncertainties. Scenario analysis can then help develop further how the uncertainties could unfold and affect the projects. Payoff matrix and decision tree (using real option valuation) analysis tools can then help make a decision on which project to pursue. Finally, these projects cannot be evaluated in a vacuum. Mapping the portfolio of projects is necessary to make sure the company diversifies the risk. This paper includes an illustration of the methodology by applying the tools to a real life example that has been tested in several executive agribusiness educational workshops. A list of psychological traps to avoid and be mindful of when making decisions in an uncertain environment is also proposed.

description: Photometric VRI and spectroscopic (6000-9500 A) observations of high proper motion stars discovered during the first phase of the SuperCOSMOS RECONS (SCR) search are used to estimate accurate distances to eight new nearby red dwarfs, including probable 10 pc sample members SCR 1845-6357 (M8.5V at 4.6 pc), the binary SCR 0630-7643AB (M6.0VJ at 7.0 pc), and SCR 1138-7721 (M5.0V at 9.4 pc). Distance estimates are determined using a suite of new photometric color-Mk relations defined using a robust set of nearby stars with accurate VRIJHK photometry and trigonometric parallaxes. These relations are utilized, with optical and infrared photometry, to estimate distances on a uniform system (generally good to 15%) for two additional samples of red nearby star candidates: several recently discovered members of the solar neighborhood, and known faint stars with proper motions in excess of 1.0"/yr south of DEC = -57.5. Of those without accurate trigonometric parallax measurements, there are five stars in the first sample and three in the second that are likely to be within 10 pc. The two nearest are SO 0253+1652 (M7.0V at 3.7 pc) and DEN 1048-3956 (M8.5V at 4.5 pc). When combined with SCR 1845-6357, these three stars together represent the largest increase in the 5 pc sample in several decades. Red spectra are presented for the red dwarfs and types are given on the RECONS standard spectral system. Red spectra are also given for two new nearby white dwarfs for which we estimate distances from the photometry of less than 20 pc -- WD 0141-675 (LHS 145, 9.3 pc) and SCR 2012-5956 (17.4 pc). WD 0141-675 brings the total number of systems nearer than 10 pc discussed in this paper to 12.

description: Recently, learning-based approaches for 3D reconstruction from 2D images have gained popularity due to its modern applications, e.g., 3D printers, autonomous robots, self-driving cars, virtual reality, and augmented reality. The computer vision community has applied a great effort in developing functions to reconstruct the full 3D geometry of objects and scenes. However, to extract image features, they rely on convolutional neural networks, which are ineffective in capturing long-range dependencies. In this paper, we propose to substantially improve Occupancy Networks, a state-of-the-art method for 3D object reconstruction. For such we apply the concept of self-attention within the network's encoder in order to leverage complementary input features rather than those based on local regions, helping the encoder to extract global information. With our approach, we were capable of improving the original work in 5.05% of mesh IoU, 0.83% of Normal Consistency, and more than 10X the Chamfer-L1 distance. We also perform a qualitative study that shows that our approach was able to generate much more consistent meshes, confirming its increased generalization power over the current state-of-the-art.

In this limit the time-nonlocal reduced dynamics can be cast into an effective equation of motion, the quantum Smoluchowski equation. For strongly condensed phase environments it plays a similar role as master equations in the weak coupling range. Applications for chemical, mesoscopic, and soft matter systems are discussed and reveal the substantial role of quantum fluctuations.

Interrupting polarities of gender and sexuality : consumption of same-sex pornography by Japanese women
Creators: name: Hirano, Yuki
Publisher: name: University of British Columbia
Year: 2009

description: In Japanese sexual discourses produced by women, a cultural sphere exists in which females express sexual agency through intimacy in fantasy spaces that are homosocial and/or homoerotic. In this paper, I argue that such spaces constructed at the level of fantasy may create an alternative form of women's sexual subjectivity, agency and identity that radically links women in the fantasy sphere of homoeroticism in ways distinct from Euro-North American discourses of sexuality. By examining popular Japanese literature and women's magazines, I interpret some aspects of Japanese women's homosocial and homoerotic culture, addressing the ways that analytical attention to fantasy may invite discussion concerning a diversity of cross-cultural gender and sexual ideologies. My analysis explore Japanese discourses of women's gender and sexuality, queer and/or straight. My research has been conducted through, but not limited to, my original collection of literature, comic books, TV programs, popular women's magazines, counter-cultural newsletters, documentary films and pornographic movies. I analyze contemporary discourses of gender, sexuality and fantasy circulated in women's magazines, newsletters, comic books and pornography in Japanese culture. How do we make sense of conventional images of women's beauty alongside images of sexual practices that disrupt conventional patriarchal heterosexuality, including images of sex between women, or between men, transsexuals, dolls, animation characters or even cyborgs, that are created by and for women? I argue that Japanese women's gender and sexuality are represented and discussed ambiguously, and that rich, multilayered fantasies challenge strict gender and heterosexual norms in ways that may be seen as politicizing and empowering.
A time-space tradeoff for Lehman's deterministic integer factorization method

description: Fermat's well-known factorization algorithm is based on finding a representation of natural numbers $N$ as the difference of squares. In 1895, Lawrence generalized this idea and applied it to multiples $kN$ of the original number. A systematic approach to choose suitable values for $k$ was introduced by Lehman in 1974, which resulted in the first deterministic factorization algorithm considerably faster than trial division. In this paper, we construct a time-space tradeoff for Lawrence's generalization and apply it together with Lehman's result to obtain a deterministic integer factorization algorithm with runtime complexity $O(N^{2/9+o(1)})$. This is the first exponential improvement since the establishment of the $O(N^{1/4+o(1)})$ bound in 1977.

description: We study the early time and coarsening dynamics in the Light-Heavy model, a system consisting of two species of particles ($light$ and $heavy$) coupled to a fluctuating surface (described by tilt fields). The dynamics of particles and tilts are coupled through local update rules, and are known to lead to different ordered and disordered steady state phases depending on the microscopic rates. We introduce a generalized balance mechanism in non-equilibrium systems, namely $bunchwise~balance$, in which incoming and outgoing transition currents are balanced between groups of configurations. This allows us to exactly determine the steady state in a subspace of the phase diagram of this model. We introduce the concept of $irreducible~sequences$ of interfaces and bends in this model. These sequences are non-local, and we show that they provide a coarsening length scale in the ordered phases at late times. Finally, we propose a $local$ correlation function ($\mathcal{S}$) that has a direct relation to the number of irreducible sequences, and is able to distinguish between several phases of this system through its coarsening properties. Starting from a totally disordered initial configuration, $\mathcal{S}$ displays an initial linear rise and a broad maximum. As the system evolves towards the ordered steady states, $\mathcal{S}$ further exhibits power law decays at late times that encode coarsening properties of the approach to the ordered phases. Focusing on early time dynamics, we posit coupled mean-field evolution equations governing the particles and tilts, which at short times are well approximated by a set of linearized equations, which we solve analytically. Beyond a timescale set by a lattice cutoff and preceding the onset of coarsening, our linearized theory predicts the existence of an intermediate power-law stretch, which we also find in simulations of the ordered regime of the system.

description: This paper summarizes the results from data collected during the study’s second year, 1997/98. The analysis is based on a sample of 210 smallholder farmers in Nampula Province using three different sets of production practices: the DNER/Sasakawa- Global 2000 Program (DNER/SG) high-input package (improved open-pollinated maize, 100 kg/ha each 12-24-12 and urea fertilizer on credit); improved planting and weeding practices only (using local seed, without fertilizer); and a control group of farmers using traditional practices (no improved seed or fertilizer). The objectives of the research were to: describe the characteristics, input use patterns and yield response by group; analyze the relative contribution to yield of the different technologies, environmental factors, and management practices; and assess the profitability of the three different technology types at the farm level.

description: The effect of coupling of quantized modes on transport and localization in ultrathin films with quantum size effect (QSE) is discussed. The emphasis is on comparison of films with Gaussian, exponential, and power-law long-range behavior of the correlation function of surface, thickness, or bulk fluctuations. For small-size inhomogeneities, the mode coupling is the same for inhomogeneities of all types and the transport coefficients behave in the same way. The mode coupling becomes extremely sensitive to the correlators for large-size inhomogeneities leading to the drastically distinct behavior of the transport coefficients. In high-quality films there is a noticeable difference between the QSE patterns for films with bulk and surface inhomogeneities which explains why the recently predicted new type of QSE with large oscillations of the transport coefficients can be observed mostly in films with surface-driven relaxation. In such films with surface-dominated scattering the higher modes contribute to the transport only as a result of opening of the corresponding mode coupling channels and appear one by one. Mode coupling also explains a much higher transport contribution from the higher modes than it is commonly believed. Possible correlations between the inhomogeneities from the opposite walls provide, because of their oscillating response to the mode quantum numbers, a unique insight into the mode coupling. The presence of inhomogeneities of several sizes leads not to a mechanical mixture of QSE patterns, but to the overall shifting and smoothing of the oscillations. The results can lead to new, non-destructive ways of analysis of the buried interfaces and to study of inhomogeneities on the scales which are inaccessible for scanning techniques.

description: During 1998/99, MARD/MSU researchers followed the progress of the improved maize program in five CLUSA-assisted associations located in two different agroecological zones of Nampula Province. The objective of this study was to assess how greater involvement of farmer associations in maize intensification affects marketing costs and extension effectiveness. This preliminary report summarizes the observations on the 1998/99 production season and part of the 1999/00 marketing season, based on analysis of maize yield data and informal group interviews with participating farmer associations carried out in March and November 1999. It also discusses some of the preliminary conclusions that are emerging from the broader three-year maize intensification study.

Updated analysis of jet quenching at RHIC and LHC within the light cone path integral approach

description: We present results of a detailed analysis of experimental data on the nuclear modification factor $R_{AA}$ and the flow coefficient $v_2$ for light hadrons from RHIC for $0.2$ TeV Au+Au collisions and from LHC for $2.76$ and $5.02$ TeV Pb+Pb, and $5.44$ TeV Xe+Xe collisions. We perform calculations within the light-cone path integral approach to induced gluon emission. We use running $α_s$ which is frozen at low momenta at some value $α_{s}^{fr}$. We find that the RHIC data support somewhat larger value of $α_{s}^{fr}$. For the $χ^2$ optimized values of $α_{s}^{fr}$, the theoretical predictions are in reasonable agreement with data on $R_{AA}$ and $v_2$. Calculations made for different formation times and life-times of the QGP show that jet quenching at the RHIC and LHC energies is only weakly sensitive to the initial and final stages of the QCD matter evolution.

Interspecies evolutionary dynamics mediated by public goods in bacterial quorum sensing

description: Bacterial quorum sensing is the communication that takes place between bacteria as they secrete certain molecules into the intercellular medium that later get absorbed by the secreting cells themselves and by others. Depending on cell density, this uptake has the potential to alter gene expression and thereby affect global properties of the community. We consider the case of multiple bacterial species coexisting, referring to each one of them as a genotype and adopting the usual denomination of the molecules they collectively secrete as public goods. A crucial problem in this setting is characterizing the coevolution of genotypes as some of them secrete public goods (and pay the associated metabolic costs) while others do not but may nevertheless benefit from the available public goods. We introduce a network model to describe genotype interaction and evolution when genotype fitness depends on the production and uptake of public goods. The model comprises a random graph to summarize the possible evolutionary pathways the genotypes may take as they interact genetically with one another, and a system of coupled differential equations to characterize the behavior of genotype abundance in time. We study some simple variations of the model analytically and more complex variations computationally. Our results point to a simple trade-off affecting the long-term survival of those genotypes that do produce public goods. This trade-off involves, on the producer side, the impact of producing and that of absorbing the public good. On the non-producer side, it involves the impact of absorbing the public good as well, now compounded by the molecular compatibility between the producer and the non-producer. Depending on how these factors turn out, producers may or may not survive.
