description: Cardinality estimation is a fundamental task in database query processing and optimization. As shown in recent papers, machine learning (ML)-based approaches may deliver more accurate cardinality estimations than traditional approaches. However, a lot of training queries have to be executed during the model training phase to learn a data-dependent ML model making it very time-consuming. Many of those training or example queries use the same base data, have the same query structure, and only differ in their selective predicates. To speed up the model training phase, our core idea is to determine a predicate-independent pre-aggregation of the base data and to execute the example queries over this pre-aggregated data. Based on this idea, we present a specific aggregate-based training phase for ML-based cardinality estimation approaches in this paper. As we are going to show with different workloads in our evaluation, we are able to achieve an average speedup of 63 with our aggregate-based training phase and thus outperform indexes.

description: The present paper aims to propose an analysis and relation methodology of financial perspective, the customer perspective, the internal process perspective and the learning and growth perspective, in the same way as treated for Balanced Scorecard (BSC). The innovation, in this sense, is the treatment of all these factors together, searching to identify the cause-effect relations. Such instrument provides the understanding of all factors together that affect in the company result. Thus, the rural managers have a map to make their business decisions. Moreover, another factor that must be detached is the idiosyncrasies of rural firms, and specifically from smallholder farms. These factors are among others, the presence of family works, small scale, and family necessities versus business targets. The intention here is to provide for rural managers a efficient tool to concentrated and control the financial and non-financial aspects from a rural firm.

description: Rapid variability before and near the maximum brightness of supernovae has the potential to provide a better understanding of nearly every aspect of supernovae, from the physics of the explosion up to their progenitors and the circumstellar environment. Thanks to modern time-domain optical surveys, which are discovering supernovae in the early stage of their evolution, we have the unique opportunity to capture their intraday behavior before maximum. We present high-cadence photometric monitoring (on the order of seconds-minutes) of the optical light curves of three Type Ia and two Type II SNe over several nights before and near maximum light, using the fast imagers available on the 2.3~m Aristarchos telescope at Helmos Observatory and the 1.2~m telescope at Kryoneri Observatory in Greece. We applied differential aperture photometry techniques using optimal apertures and we present reconstructed light curves after implementing a seeing correction and the Trend Filtering Algorithm(TFA). TFA yielded the best results, achieving a typical precision between 0.01-0.04~mag. We did not detect significant bumps with amplitudes greater than 0.05~mag in any of the SNe targets in the VR-, R-, and I- bands light curves obtained. We measured the intraday slope for each light curve, which ranges between -0.37-0.36 mag/day in broadband VR, -0.19-0.31 mag/day in R band, and -0.13-0.10 mag/day in I band. We used SNe light curve fitting templates for SN 2018gv, SN 2018hgc and SN 2018hhn to photometrically classify the light curves and to calculate the time of maximum. We provide values for the maximum of SN 2018zd after applying a low-order polynomial fit and SN 2018hhn for the first time. We suggest monitoring early supernovae light curves in hotter (bluer) bands with a cadence of hours as a promising way of investigating the post-explosion photometric behavior of the progenitor stars.

description: We present a microscopic theory of equilibrium solvation in solvents with zero dipole moment and non-zero quadrupole moment (quadrupolar solvents). The theory is formulated in terms of autocorrelation functions of the quadrupolar polarization (structure factors). It can be therefore applied to an arbitrary dense quadrupolar solvent for which the structure factors are defined. We formulate a simple analytical perturbation treatment for the structure factors. The solute is described by coordinates, radii, and partial charges of constituent atoms. The theory is tested on Monte Carlo simulations of solvation in model quadrupolar solvents. It is also applied to the calculation of the activation barrier of electron transfer reactions in a cleft-shaped donor-acceptor complex dissolved in benzene with the structure factors of quadrupolar polarization obtained from Molecular Dynamics simulations.

description: The double-perovskite A$_2$BB'O$_6$ with heavy transition metal ions on the ordered B' sites is an important family of compounds to study the interplay between electron correlation and spin-orbit coupling (SOC). Here we prepared high-quality Sr$_2$MgReO$_6$ powder and single-crystal samples and performed non-resonant and resonant synchrotron x-ray diffraction experiments to investigate its magnetic ground state. By combining the magnetic susceptibility and heat capacity measurements, we conclude that Sr$_2$MgReO$_6$ exhibits a layered antiferromagnetic (AF) order at temperatures below $\sim$ 55 K with a propagation vector q = (001), which contrasts the previously suspected spin glass state. Our works clarify the magnetic order in Sr$_2$MgReO$_6$ and demonstrate it as a candidate system to look for magnetic octupolar orders and exotic spin dynamics.

description: We re-examine current and future constraints on a heavy dilaton coupled to a simple dark sector consisting of a Majorana fermion or a Stückelberg vector field. We include three different treatments of dilaton-Higgs mixing, paying particular attention to a gauge-invariant formulation of the model. Moreover, we also invite readers to re-examine effective field theories of vector dark matter, which we show are missing important terms. Along with the latest Higgs coupling data, heavy scalar search results, and dark matter density/direct detection constraints, we study the LHC bounds on the model and estimate the prospects of dark matter production at the future HL-LHC and 100 TeV FCC colliders. We additionally compute novel perturbative unitarity constraints involving vector dark matter, dilaton and gluon scattering.

description: We construct new, efficient, and accurate high-order finite differencing operators which satisfy summation by parts. Since these operators are not uniquely defined, we consider several optimization criteria: minimizing the bandwidth, the truncation error on the boundary points, the spectral radius, or a combination of these. We examine in detail a set of operators that are up to tenth order accurate in the interior, and we surprisingly find that a combination of these optimizations can improve the operators' spectral radius and accuracy by orders of magnitude in certain cases. We also construct high-order dissipation operators that are compatible with these new finite difference operators and which are semi-definite with respect to the appropriate summation by parts scalar product. We test the stability and accuracy of these new difference and dissipation operators by evolving a three-dimensional scalar wave equation on a spherical domain consisting of seven blocks, each discretized with a structured grid, and connected through penalty boundary conditions.

description: We present heavy element abundance measurements for 16 DAO white dwarfs, determined from Far-Ultraviolet Spectroscopic Explorer {FUSE} spectra. Evidence of absorption by heavy elements was found in the spectra of all the objects. Measurements were made using models that adopted the temperatures, gravities and helium abundances determined from both optical and FUSE data by Good et al. (2004). Despite the different evolutionary paths that the types of DAO white dwarfs are thought to evolve through, their abundances were not found to vary significantly, apart from for the silicon abundances. Abundances measured when the FUSE derived values of temperature, gravity and helium abundance were adopted were, in general, a factor 1-10 higher than those determined when the optical measure of those parameters was used. Satisfactory fits to the absorption lines were achieved in approximately equal number. The models that used the FUSE determined parameters seemed better at reproducing the strength of the nitrogen and iron lines, while for oxygen, the optical parameters were better.

description: In this paper we attempt to compare the responses of consumers and professionals to questions related to organic food retailing, in order to highlight the differences and the similarities of viewpoints between them and to understand the links between consumer perception of organic food and the sales channel. In order to do this, we analyse the results of three studies, two of them conducted with consumers, the third one with professionals. The first study deals with the links between consumer trust orientations and the frequentation of the different sales channels where organic food can be found. The results of this study conducted in France and Germany show that consumers in organic food stores put trust in their store but are neither the heaviest nor the most trusting consumers. Consumers in hypermarkets or supermarkets do not really trust the store, and only really trust the label. In the second study, respondents were asked what their preferred outlet for organic products would be and why. Results show that organic food consumers like being something more than an anonymous consumer when shopping. They seem to appreciate markets particularly, and appear to attach no particular value to organic food stores, nor to the acknowledged greater convenience of shopping in supermarkets. This study also raises interesting questions relating to the experience of purchasing in terms of shop location, image and atmosphere, and factors that contribute to consumer trust in organic foods. The third study is based upon two surveys (autumn 2003 and autumn 2004) among organic food stores in France, on market development and on actors' perception of their situation and their customers. According to shopkeepers, customers of organic food stores are looking more for quality and competence, than for attractive prices, and attach more and more value to traceability and trustworthiness. This paper shows important similarities of viewpoints between consumers and organic food stores shopkeepers, and gives researchers and professionals a better insight into the links between consumer perception of organic food and the sales channel.

A nonlinear model of demand and costs, including firm specific and industry cost shift variables is estimated for each of the four leading supermarkets. Cost pass through rates for industry wide shifts are near 100%; for firm specific costs they range between 32 and 47 percent, suggesting that substantial differentiation and related market power. A test for focal point collusion finds that channel firms elevated retail prices when the Northeast Dairy Compact elevated and stabilized raw milk prices.

description: This research examines market performance in the U.S. food manufacturing product classes for 1982 and the effect cooperatives have as market participants. It addresses the public policy concern that cooperatives may obtain market power through favorable public policy and may exercise that market power to the detriment of society through under price-enhancement. Because of this concern the partial antitrust exemption granted cooperatives under the Capper-Volstead Act of 1992 is likely to re-emerge on the public policy agenda. A basic industrial organization structure-performance model extended by the theory of cooperatives is used to test the effect of cooperatives on market performance, here measured as the market's price-cost margin. After controlling for differences in the geographic size of markets and the effects of demand growth on prices, key structural elements affecting margins included measures of concentration, the degree of product differentiation and capital utilization and the minimum efficient scale. Cooperative theory predicts improved performance in markets where cooperatives are present through the 'competitive yardstick' effect. The underlying hypothesis that the degree of cooperative participation is inversely related to the level of price-cost margins has rarely been fully tested across a large cross section of food manufacturing markets because of limited market data on cooperation participation. This study used a Special Tabulation of Census of Manufacturers data for 1982 to construct a continuous variable representing the aggregate market share of the 100 largest agricultural marketing cooperatives in each of 134 food product classes. This extended structure-performance model was then estimated using ordinary least squares methods. The cooperative share of market sales had a significant, negative impact on the level of margins supporting the yardstick effect hypothesis that cooperatives improve market performance. Product differentiation, measured by advertising-to-sales ratios, was positively related to margins but at a decreasing rate as advertising intensity increased. Capital intensity and minimum efficient scale were insignificant factors. These results serve to confirm the basic industrial organization model and provide empirical support for the competitive yardstick effect of cooperatives on market performance.
Breastfeeding, marital satisfaction, and family functioning in primiparous couples
Creators: name: Butt, Yolanda A.
Publisher: name: University of British Columbia
Year: 2009

description: Little is known about the impact of infant-feeding practices on the marriage and on the functioning of the family. Research to date has focussed on the physiological, developmental, and psychological benefits of breastfeeding for the infant; the determinants of breastfeeding; and the sexual relations between the parents postpartum but has ignored the immediate and longer-term effects of infant-feeding practices on the family. The objective of this study was to determine whether breastfeeding predicts marital satisfaction and family functioning for first-time parents. Secondary data from the National Longitudinal Survey of Children and Youth was analyzed for 1600 primiparous parents; 1444 of the persons most knowledgeable (PMK) were female while 156 were male. A review of the statistical findings reveals that there is evidence for the positive effect of breastfeeding on immediate marital satisfaction and family functioning. What is surprising, however, is that the proposed model is only relevant for fathers whose wives are currently breastfeeding. The relationship between breastfeeding and family functioning is mediated by marital satisfaction and moderated by social support for fathers. This study also includes an analysis of the breastfeeding practices (duration and reasons for cessation) of the families surveyed from across the provinces of Canada.

description: In models with extra dimensions, a black hole evaporates both in the bulk and on the visible brane, where standard model fields live. The exact emissivities of each particle species are needed to determine how the black hole decay proceeds. We compute and discuss the absorption cross-sections, the relative emissivities and the total power output of all known fields in the evaporation phase. Graviton emissivity is highly enhanced as the spacetime dimensionality increases. Therefore, a black hole loses a significant fraction of its mass in the bulk. This result has important consequences for the phenomenology of black holes in models with extra dimensions and black hole detection in particle colliders.

description: The possibility of multiple phase diagram in the novel superconductor Na_{x}CoO_{2}yH_{2}O is analyzed on the basis of the multi-orbital Hubbard model including the atomic spin-orbit coupling. We have shown that the spin triplet pairing state is stable in this model. The p-wave (f-wave) state is stabilized when the Hund's rule coupling is large (small). In the precedent paper, we have determined the direction of d-vector at T=Tc and H=0 within the linearized Dyson-Gorkov equation. In this paper, the pairing state below Tc and under the magnetic field is determined within the weak coupling approximation including the paramagnetic effect. We find that the p+f coexistent state is stabilized at low temperatures in a part of parameter range. We point out that the phase diagram in the H-T plane is quite different between the p-wave, f-wave and p+f-wave superconductivities. The characteristics of each phase are clarified by showing the magnetic susceptibility and specific heat. We discuss the comparison with experimental results and suggest some future experiments to detect the multiple phase transition.

description: As a part of an ongoing effort to characterise the young stellar populations in the Large Magellanic Cloud, we present HST-WFPC2 broad and narrow band imaging of two fields with recent star formation activity in the Tarantula region. A population of objects with Halpha and/or Balmer continuum excess was identified. On account of the intense Halpha emission (equivalent widths up to several tens of Angstroms), its correlation with the Balmer continuum excess and the stars' location on the HR diagram, we interpret them as low mass (~1-2 Mo) Pre-Main Sequence stars. In this framework, the data show that coeval high and low mass stars have significantly different spatial distributions, implying that star formation processes for different ranges of stellar masses are rather different and/or require different initial conditions. We find that the overall slope of the mass function of the young population is somewhat steeper than the classical Salpeter value and that the star formation density of this young component is 0.2-0.4 Mo/yr/kpc2, i.e. intermediate between the value for an active spiral disk and that of a starburst region. The uncertainties associated with the determination of the slope of the mass function and the star formation density are thoroughly discussed.

description: We study the issue of coupling among 4-simplices in the context of spin foam models obtained from a group field theory formalism. We construct a generalisation of the Barrett-Crane model in which an additional coupling between the normals to tetrahedra, as defined in different 4-simplices that share them, is present. This is realised through an extension of the usual field over the group manifold to a five argument one. We define a specific model in which this coupling is parametrised by an additional real parameter that allows to tune the degree of locality of the resulting model, interpolating between the usual Barrett-Crane model and a flat BF-type one. Moreover, we define a further extension of the group field theory formalism in which the coupling parameter enters as a new variable of the field, and the action presents derivative terms that lead to modified classical equations of motion. Finally, we discuss the issue of renormalisation of spin foam models, and how the new coupled model can be of help regarding this.

description: In contrast to single-equation cross-sectional studies of private label share, developing a complete understanding of the nature of the competitive interaction between national brands and private labels requires an understanding of the determinants of both demand and strategic pricing decisions by firms. Consequently, we estimate a simultaneous system of share and price for private labels and national brands. From the empirical results, two measures of market response are derived. The unilateral demand elasticity measures the pure "own" demand response, while the residual (or "total") elasticity also captures the impact of competitive price reaction (Baker and Bresnahan 1985). When taken together, these provide important strategic insights into the pricing interaction between national brands and private labels. In our empirical analysis, we employ a flexible, non-linear demand specification, the Linear Approximate Almost Ideal Demand System (LA/AIDS, Deaton and Muellbauer 1980a), and specify the price reaction equations derived under the LA/AIDS demand specification. Incorporating LA/AIDS demands into a structural equation framework represents an important departure from previous demand specifications in competitive analysis. Using the proposed LA/AIDS framework, we perform a detailed intra-category analysis using data on six individual categories: bread, milk, pasta, instant coffee, butter and margarine. In addition, in an attempt to generalize the results to a broader set of categories and in order to enable us to compare our results to previous cross-section studies, we also estimate using a sample pooled across 125 categories and 59 geographic markets. Consistent with our objectives, we find 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. Further, estimates of residual demand elasticities suggest that examination of partial demand elasticities alone may provide an incomplete picture of the ability of brands to raise price. Managerial implications, limitations and suggestion for future research are discussed.

description: In Gaia DR2, the unprecedented high-precision level reached in sub-mas for astrometry and mmag for photometry. Using cluster members identified with these astrometry and photometry in Gaia DR2, we can obtain a reliable determination of cluster properties. However, because of the shortcoming of Gaia spectroscopic observation in dealing with densely crowded cluster region, the number of radial velocity and metallicity for cluster member stars from Gaia DR2 is still lacking. In this study, we aim to improve the cluster properties by combining the LAMOST spectra. In particular, we provide the list of cluster members with spectroscopic parameters as an add-value catalog in LAMOST DR5, which can be used to perform detailed study for a better understanding on the stellar properties, by using their spectra and fundamental properties from the host cluster. We cross-matched the spectroscopic catalog in LAMOST DR5 with the identified cluster members in Cantat-Gaudin et al.2018 and then used members with spectroscopic parameters to derive statistical properties of open clusters. We obtained a list of 8811 members with spectroscopic parameters and a catalog of 295 cluster properties. In addition, we study the radial and vertical metallicity gradient and age-metallicity relation with the compiled open clusters as tracers, finding slopes of -0.053$\pm$0.004 dex kpc$^{-1}$, -0.252$\pm$0.039 dex kpc$^{-1}$ and 0.022$\pm$0.008 dex Gyr$^{-1}$, respectively. Both slopes of metallicity distribution relation for young clusters (0.1 Gyr < Age < 2 Gyr) and the age-metallicity relation for clusters within 6 Gyr are consistent with literature results. In order to fully study the chemical evolution history in the disk, more spectroscopic observations for old and distant open clusters are needed for further investigation.

description: Measuring the geometry of multi-planet extrasolar systems can provide insight into their dynamical history and the processes of planetary formation. Such measurements are challenging for systems detected through indirect techniques such as radial velocity and transit, having only been measured for a handful of systems to-date. We aimed to place constraints on the orbital geometry of the outer planet in the $π$ Mensae system, a G0V star at 18.3 pc host to a wide-orbit super-jovian ($M\sin i = 10.02\pm0.15$ $M_{\rm Jup}$) with a 5.7-year period and an inner transiting super-earth ($M=4.82\pm0.85$ $M_\oplus$) with a 6.3-d period. We combined astrometric measurements from the Hipparcos and Gaia satellites with a precisely determined spectroscopic orbit in an attempt to constrain the inclination of the orbital plane of the outer planet. We measured an inclination of $i_b=49.9_{-4.5}^{+5.3}$ deg for the orbital plane of $π$ Mensae b, leading to a direct measurement of its mass of $13.01_{-0.95}^{+1.03}$ $M_{\rm Jup}$. We found a significant mutual inclination between the orbital planes of the two planets; a 95% credible interval for $i_{\rm mut}$ of between $34.5^\circ$ and $140.6^\circ$ after accounting for the unknown position angle of the orbit of $π$ Mensae c, strongly excluding a co-planar scenario for the two planets within this system. All orbits are stable in the present-day configuration, and secular oscillations of planet c's eccentricity are quenched by general relativistic precession. Planet c may have undergone high eccentricity tidal migration triggered by Kozai-Lidov cycles, but dynamical histories involving disk migration or in situ formation are not ruled out. Nonetheless, this system provides the first direct evidence that giant planets with large mutual inclinations have a role to play in the origins and evolution of some super-Earth systems.

Demand and Price Analysis

description: A quantity surcharge exists when the unit cost of a given brand is higher for a large-size package than for a smaller one. This paper examines some product and household characteristics that influence observed quantity surcharging practices. Results indicate that the propensity to buy a large-size package of a product is positively influenced by the extent of a household's usage of that product, procurement cost, and carrying capacity, and is negatively influenced by the propensity to price search. A retailer's decision to levy a quantity surcharge is, in turn, influenced by the demand for the product, the propensity to buy large-size packages, and to some extent the product's carrying cost.
Private Initiatives for Rural Development: Ideological Cop Out or Engine for Progress

description: This report identifies a research and policy agenda that can contribute to rural development and antipoverty initiatives during the 1990s. It integrates a discussion of private initiatives for rural development into a broader discussion of the issues. Two theories of underdevelopment and poverty, one motivational and the other structural, serve as a basis for defining quite different research and policy agendas. To provide some closure of these divergent approaches, it is argued herein that economists must more rigorously examine the philosophical and political economic foundations of their theories. One reason this is needed is that recent contributions to the theory of public choice rehabilitate the classical economic argument for minimal state action. An effective and efficient rural development policy, moreover, must analyze the distribution system that delivers goods and services to rural communities. There is evidence that noncompetitive distribution channels distort prices in some rural communities and transfer wealth from them. In addition, many rural communities are at the end of distribution channels. Therefore, even in competitively structured channels, the relatively high costs of delivered goods and services for productive activity and consumption retard economic development and standards of living. Changes in the structure of rural households and the employment shift out of agriculture limit the ability of rural families to offset these higher costs via traditional household production activities. Cooperatives of many types-agricultural, rural electric and telephone, wholesale grocery, and consumer cooperatives-have been a major component in market-oriented public policies to promote effective distribution of goods and services to rural America. More recent institutional innovations that enhance private initiatives are public venture capital funds and nonprofit agencies. Research on rural distribution channels and the appropriate mix of private and public initiatives should be a major component of any new rural development policy.

description: Long-slit optical spectra along the major axis of spiral galaxies constitute a main source of information concerning the kinematics of galaxies. In highly inclined spiral galaxies the long-slit spectrum is distorted by dust, which obscures the innermost parts of the galaxy and eliminates the relevant kinematic information. This effect however may provide information concerning the amount and the spatial distribution of dust. Here I review previous attempts to quantify the internal extinction of spiral galaxies using kinematic information and I discuss the relevant theoretical models. Finally I suggest possible directions for further studies on this subject.
