Nutrition information on food package labels : consumer use in grocery stores and input on education issues
Creators: name: Romses, Kathy
Publisher: name: University of British Columbia
Year: 2009

description: This study investigates consumers' use of nutrition information on food package labels in a purchase decision context, obtains consumers' input on the types of education assistance they want to help them to use this information, who they believe should be providing this assistance, and their suggested methods for distributing or providing this assistance. Approximately 7% of 2,316 consumers observed choosing foods from two large grocery stores in the Greater Vancouver area were observed using the nutrition information on food package labels. Eighty-seven consumers who were using this information were interviewed in the store and 38 of these consumers were further interviewed by telephone. In-store participants shared their views on the nutrition information used to help with their purchase decision, the reasons for use, and the education assistance required to facilitate their use of this information. Telephone participants also provided their input on who should provide the education and how it should be distributed. In-store participants reported using the nutrition information primarily for limiting nutrients perceived to be harmful (fat, calories, sugar, additives, and salt). Fourteen percent of the in-store participants initially reported that they needed help using the nutrition information on the label. The percentage of telephone participants requesting help with the label increased from 13% to 47% when proposed changes to the nutrition label by Health Canada were explained. Sixty-eight percent of those requesting help wanted it directed towards increasing their understanding of the types of fats. Fifty percent of telephone participants reported that food companies should provide the educational support, followed by government (37%), health professionals (34%>), grocery stores (16%>), and public schools (8%). Telephone participants chose handouts in the grocery stores in holders close to the foods, newspapers, and handouts in health offices as the top three methods of providing education information to consumers. Further research with consumers who don't use labels is required to obtain an overall view of consumers' perspectives. Consumers are the ultimate end users of the nutrition information on food labels, which makes their input particularly important. The results of this study are timely as Health Canada reviews its policies on nutrition labelling and nutrition claims which includes a public education component. Theories and models from adult education are used to help explain the findings.

About the quantum-kinetic derivation of boundary conditions for quasiparticle Boltzmann equations at interfaces

description: Quite a many electron transport problems in condensed matter physics are analyzed with a quasiparticle Boltzmann equation. For sufficiently slowly varying weak external potentials it can be derived from the basic equations of quantum kinetics, provided quasiparticles can be defined and lead to a pole in the quantum-mechanical propagators. The derivation breaks down, however, in the vicinity of an interface which constitutes an abrupt strong perturbation of the system. In this contribution we discuss in a tutorial manner a particular technique to systematically derive, for a planar, nonideal interface, matching conditions for the quasi-particle Boltzmann equation. The technique is based on pseudizing the transport problem by two auxiliary interface-free systems and matching Green functions at the interface. Provided quasiparticles exist in the auxiliary systems, the framework can be put onto the semiclassical level and the desired boundary conditions result. For ideal interfaces, the conditions can be guessed from flux conservation, but for complex interfaces this is no longer the case. The technique presented in this work is geared towards such interfaces.

These new Hartree--Fock dynamics is still of mean field type but includes memory effects which are generically nonlocal also in space.

description: The back-reaction of dispersed rigid fibers to turbulence is analyzed by means of a state-of-the-art fully-coupled immersed boundary method. The following universal scenario is identified: turbulence at large scales looses a consistent part of its kinetic energy (via a Darcy friction term), which partially re-appears at small scales where a new range of energy-containing scales does emerge. Large-scale mixing is thus depleted in favor of a new mixing mechanism arising at the smallest scales. Anchored fibers cause the same back-reaction to turbulence as moving fibers of large inertia. Our results thus provide a link between two apparently separated realms: the one of porous media and the one of suspension dynamics.

The magnetic field $B$ is supposed to be nonzero and local. We show that the essential spectrum is $[-\frac14α^2,\infty)$, as for the non-magnetic operator with a straight $Γ$, and demonstrate a sufficient condition for the discrete spectrum of $H$ to be empty.

description: We propose a class of numerical integration methods for stochastic Poisson systems (SPSs) of arbitrary dimensions. Based on the Darboux-Lie theorem, we transform the SPSs to their canonical form, the generalized stochastic Hamiltonian systems (SHSs), via canonical coordinate transformations found by solving certain PDEs defined by the Poisson brackets of the SPSs. An a-generating function approach with α\in [0,1] is then used to create symplectic discretizations of the SHSs, which are then transformed back by the inverse coordinate transformation to numerical integrators for the SPSs. These integrators are proved to preserve both the Poisson structure and the Casimir functions of the SPSs. Applications to a three-dimensional stochastic rigid body system and a three-dimensional stochastic Lotka-Volterra system show efficiency of the proposed methods.
Bounds on the attractor dimension for low-R m wall-bound magnetohydrodynamic turbulence

description: Steady Low $R_m$ MHD turbulence is investigated here through estimates of upper bounds for attractor dimension. A flow between two parallel walls with an imposed perpendicular magnetic field is considered. The flow is defined by its maximum velocity and the intensity of the magnetic field. Given the corresponding Reynolds and Hartmann numbers, we derive an upper bound for the dimension of the attractor and find out which modes must be chosen to achieve this bound. Thier, are compared to heuristics estimates for the size of the smallest scales and anisotropy of the turbulence. We identify boundaries separating different sets of modes in the space of non-dimensional parameters, which are reminiscent of three important previously identified transitions observed in the real flow. The first boundary separates classical hydrodynamic sets of modes from MHD sets where anisotropy takes the form of a ``Joule cone''. The second boundary separates 3D MHD sets from quasi-2D MHD sets. The third separates sets where all the modes exhibit the same boundary layer thickness or so, and sets where many different ``boundary layer modes'' co-exists in the set. The non-dimensional relations defining these boundaries are then compared to the heuristics known for the transition between isotropic and anisotropic MHD turbulence, 3D and quasi-2D MHD turbulence and that between a turbulent and a laminar Hartmann layer. In addition to this 3D approach, we also determine upper bounds for the dimension of forced turbulent flows modelled using a 2D MHD equation, relevant in the quasi-2D MHD regime. The advantage of this 2D approach is that, while upper bounds are quite loose in three dimensions, optimal upper bounds exist for the 2D nonlinear term. This allows us to derive realistic attractor dimensions for quasi-2D MHD flows.

description: Survival of many family farms is dependent on successful intergenerational transfer. Given the importance of succession in the farm sector, the purpose of this paper is to examine factors that are likely to influence succession decisions on U.S. farms. The paper uses 2001 ARMS data and a multinomial Logit (MNL) regression to estimate family succession, non-family succession, and farm exit decisions of farm households in the U.S. Model choice and specification issues are discussed. Results indicate that operator's education, household wealth, growth in farm size, and farm debt are important factors that determine succession decisions. Additionally, farm specialization is taken into consideration when farm operators make their succession plans.

description: We present observations of the famous OH/IR star OH26.5+0.6 obtained using the Mid-Infrared Interferometric Instrument MIDI at the European Southern Observatory (ESO) Very Large Telescope Interferometer VLTI. The emission of the dusty envelope, spectrally dispersed at a resolution of 30 from 8 to 13.5 micron, appears resolved by a single dish UT telescope. In particular the angular diameter increases strongly within the silicate absorption band. Moreover an acquisition image taken at 8.7 micron exhibits, after deconvolution, a strong asymmetry. The axis ratio is 0.75+/-0.07 with the FWHM of the major and minor axis which are 286mas and 214mas respectively. The measured PA angle, 95 degrees +/-6 degrees is reminiscent of the asymmetry in the OH maser emission detected at 1612MHz by Bowers & Johnston (1990) for this star. In interferometric mode the UT1-UT3 102m baseline was employed to detect the presence of the star. No fringes have been found with a detection threshold estimated to be of the order of 1% of the total flux of the source, i.e. 5-8 Jy. These observations were carried out during the phase of maximum luminosity of the star, when the dust shell is more diluted and therefore the chance to detect the central source maximized. We modeled the dusty environment based on the work of Justannont et al. (1996). In particular, the failure to detect fringes provides strong constraints on the opacities in the inner regions of the dust shell or in the close vicinity of the star.

description: AMANDA-II is the largest neutrino telescope collecting data at the moment, and its main goal is to search for sources of high energy extra-terrestrial neutrinos. The detection of such sources could give non-controversial evidence for the acceleration of charged hadrons in cosmic objects like Supernova Remnants, Micro-quasars, Active Galactic Nuclei or Gamma Ray Bursts. No significant excess has been found in searching for neutrinos from both point-like and non-localized sources. However AMANDA-II has significantly improved analysis techniques for better signal-to-noise optimization. The km$^3$-scale IceCube telescope will enlarge the observable energy range and improve the sensitivities of high energy neutrino searches due to its 30 times larger effective area.

description: Secondary analysis or the reuse of existing survey data is a common practice among social scientists. Searching for relevant datasets in Digital Libraries is a somehow unfamiliar behaviour for this community. Dataset retrieval, especially in the social sciences, incorporates additional material such as codebooks, questionnaires, raw data files and more. Our assumption is that due to the diverse nature of datasets, document retrieval models often do not work as efficiently for retrieving datasets. One way of enhancing these types of searches is to incorporate the users' interaction context in order to personalise dataset retrieval sessions. As a first step towards this long term goal, we study characteristics of dataset retrieval sessions from a real-life Digital Library for the social sciences that incorporates both: research data and publications. Previous studies reported a way of discerning queries between document search and dataset search by query length. In this paper, we argue the claim and report our findings of an indistinguishability of queries, whether aiming for a dataset or a document. Amongst others, we report our findings of dataset retrieval sessions with respect to query characteristics, interaction sequences and topical drift within 65,000 unique sessions.

description: China's 10-year old wheat futures market, the China Zhengzhou Commodity Exchange (CZCE) has been in stable development since establishment and is expected to be integrated to the world market after China joined WTO. This paper compares the price behavior of CZCE with that of the Chicago Board of trade (CBOT) in the US using ARCH/GARCH based univariate and multivariate time series models for the period between 1999 and 2003, around when China joined the World Trade Organization (WTO). Results show both markets can be modeled by an ARCH (1) or a GARCH (1,1), and the models have better fit when conditional error variance is t distributed. The price series in CZCE and CBOT are interrelated but not cointegrated. The existing interrelations between the two markets are significant and asymmetric, where CBOT holds a dominant position in the interactions while CZCE is more like a follower.

description: Oshtoran Syndrome, also known as H63D syndrome type-3, is a multifactorial, meta-syndromic disorder characterized by a variety of clinical manifestations. These include irregular iron homeostasis, microinflammatory events, neuropsychiatric disorders, multi-organ pathologies and especially autonomic dysfunctions involving the central nervous system, the autonomic nervous system and the innate immune system. The disease is complex and requires a comprehensive, multidisciplinary approach to diagnosis and treatment. There is evidence that the homozygous mutation of the HFE gene H63D plays a role, similar to Wilson's disease, but with NTBI iron instead of copper as the causative agent. This mutation has been linked to a number of diseases, including liver disease, diabetes mellitus, pseudo-diabetes, heart disease, neurodegenerative diseases and many more symptoms.

description: Distributed deep learning systems (DDLS) train deep neural network models by utilizing the distributed resources of a cluster. Developers of DDLS are required to make many decisions to process their particular workloads in their chosen environment efficiently. The advent of GPU-based deep learning, the ever-increasing size of datasets and deep neural network models, in combination with the bandwidth constraints that exist in cluster environments require developers of DDLS to be innovative in order to train high quality models quickly. Comparing DDLS side-by-side is difficult due to their extensive feature lists and architectural deviations. We aim to shine some light on the fundamental principles that are at work when training deep neural networks in a cluster of independent machines by analyzing the general properties associated with training deep learning models and how such workloads can be distributed in a cluster to achieve collaborative model training. Thereby we provide an overview of the different techniques that are used by contemporary DDLS and discuss their influence and implications on the training process. To conceptualize and compare DDLS, we group different techniques into categories, thus establishing a taxonomy of distributed deep learning systems.

description: Self-similar networks with scale-free degree distribution have recently attracted much attention, since these apparently incompatible properties were reconciled in a paper by Song et al. by an appropriate box-counting method that enters the measurement of the fractal dimension. We study two genetic regulatory networks ({\it Saccharomyces cerevisiae} and {\it Escherichai coli} and show their self-similar and scale-free features, in extension to the datasets studied by Song et al. Moreover, by a number of numerical results we support the conjecture that self-similar scale-free networks are not assortative. From our simulations so far these networks seem to be disassortative instead. We also find that the qualitative feature of disassortativity is scale-invariant under renormalization, but it appears as an intrinsic feature of the renormalization prescription, as even assortative networks become disassortative after a sufficient number of renormalization steps.

In spite of the considerably smaller V-O-V bond angle in CaVO3 the LDA+DMFT spectra of the two systems for energies EE_F shows more pronounced, albeit still small, differences. This is in contrast to earlier theoretical and experimental conclusions, but in good agreement with recent bulk-sensitive photoemission and x-ray absorption experiments.

description: Bundle recommendation seeks to recommend a bundle of related items to users to improve both user experience and the profits of platform. Existing bundle recommendation models have progressed from capturing only user-bundle interactions to the modeling of multiple relations among users, bundles and items. CrossCBR, in particular, incorporates cross-view contrastive learning into a two-view preference learning framework, significantly improving SOTA performance. It does, however, have two limitations: 1) the two-view formulation does not fully exploit all the heterogeneous relations among users, bundles and items; and 2) the "early contrast and late fusion" framework is less effective in capturing user preference and difficult to generalize to multiple views. In this paper, we present MultiCBR, a novel Multi-view Contrastive learning framework for Bundle Recommendation. First, we devise a multi-view representation learning framework capable of capturing all the user-bundle, user-item and bundle-item relations, especially better utilizing the bundle-item affiliations to enhance sparse bundles' representations. Second, we innovatively adopt an "early fusion and late contrast" design that first fuses the multi-view representations before performing self-supervised contrastive learning. In comparison to existing approaches, our framework reverses the order of fusion and contrast, introducing the following advantages: 1)our framework is capable of modeling both cross-view and ego-view preferences, allowing us to achieve enhanced user preference modeling; and 2) instead of requiring quadratic number of cross-view contrastive losses, we only require two self-supervised contrastive losses, resulting in minimal extra costs. Experimental results on three public datasets indicate that our method outperforms SOTA methods.

description: The prediction of stellar ($γ$,$α$) reaction rates for heavy nuclei is based on the calculation of ($α$,$γ$) cross sections at sub-Coulomb energies. These rates are essential for modeling the nucleosynthesis of so-called $p$-nuclei. The standard calculations in the statistical model show a dramatic sensitivity to the chosen $α$-nucleus potential. The present study explains the reason for this dramatic sensitivity which results from the tail of the imaginary $α$-nucleus potential in the underlying optical model calculation of the total reaction cross section. As an alternative to the optical model, a simple barrier transmission model is suggested. It is shown that this simple model in combination with a well-chosen $α$-nucleus potential is able to predict total $α$-induced reaction cross sections for a wide range of heavy target nuclei above $A \gtrsim 150$ with uncertainties below a factor of two. The new predictions from the simple model do not require any adjustment of parameters to experimental reaction cross sections whereas in previous statistical model calculations all predictions remained very uncertain because the parameters of the $α$-nucleus potential had to be adjusted to experimental data. The new model allows to predict the reaction rate of the astrophysically important $^{176}$W($α$,$γ$)$^{180}$Os reaction with reduced uncertainties, leading to a significantly lower reaction rate at low temperatures. The new approach could also be validated for a broad range of target nuclei from $A \approx 60$ up to $A \gtrsim 200$.

description: We explore physically self-consistent models of dusty molecular tori in Active Galactic Nuclei (AGN) with the goal of interpreting VLTI observations and fitting high resolution mid-IR spectral energy distributions (SEDs). The input dust distribution is analytically calculated by assuming hydrostatic equilibrium between pressure forces - due to the turbulent motion of the gas clouds - and gravitational and centrifugal forces as a result of the contribution of the nuclear stellar distribution and the central black hole. For a fully three-dimensional treatment of the radiative transfer problem through the tori we employ the Monte Carlo code MC3D. We find that in homogeneous dust distributions the observed mid-infrared emission is dominated by the inner funnel of the torus, even when observing along the equatorial plane. Therefore, the stratification of the distribution of dust grains - both in terms of size and composition - cannot be neglected. In the current study we only include the effect of different sublimation radii which significantly alters the SED in comparison to models that assume an average dust grain property with a common sublimation radius, and suppresses the silicate emission feature at 9.7 micron. In this way we are able to fit the mean SED of both type I and type II AGN very well. Our fit of special objects for which high angular resolution observations (less than 0.3 arcseconds) are available indicates that the hottest dust in NGC 1068 reaches the sublimation temperature while the maximum dust temperature in the low-luminosity AGN Circinus falls short of 1000 K.

description: The possible existence of four-neutron resonances close to the physical energy region is explored. Faddeev-Yakubovsky equations have been solved in configuration space using realistic nucleon-nucleon interaction models. Complex Scaling and Analytical Continuation in the Coupling Constant methods were used to follow the resonance pole trajectories, which emerge out of artificially bound tetraneutron states. The final pole positions for four-neutron states lie in the third energy quadrant with negative real energy parts and should thus not be physically observable.

description: Carbon nitride two-dimensional (2D) materials are among the most attractive class of nanomaterials, with wide range of application prospects. As a continuous progress, most recently, two novel carbon nitride 2D lattices of C3N5 and C3N4 have been successfully experimentally realized. Motivated by these latest accomplishments and also by taking into account the well-known C3N4 triazine-based graphitic carbon nitride structures, we predicted two novel C3N6 and C3N4 counterparts. We then conducted extensive density functional theory simulations to explore the thermal stability, mechanical, electronic and optical properties of these novel nanoporous carbon-nitride nanosheets. According to our results all studied nanosheets were found to exhibit desirable thermal stability and mechanical properties. Non-equilibrium molecular dynamics simulations on the basis of machine learning interatomic potentials predict ultralow thermal conductivities for these novel nanosheets. Electronic structure analyses confirm direct band gap semiconducting electronic character and optical calculations reveal the ability of these novel 2D systems to adsorb visible range of light. Extensive first-principles based results by this study provide a comprehensive vision on the stability, mechanical, electronic and optical responses of C3N4, C3N5 and C3N6 as novel 2D semiconductors and suggest them as promising candidates for the design of advanced nanoelectronics and energy storage/conversion systems.

description: According to a Virginia-North Carolina watershed survey, farmers view advisory services as having the effect of decreasing pesticide use. However, analysis of pesticide use shows that hired staff, scouting personnel, and extension agents are associated with higher pesticide toxicity applied to cotton while chemical dealers and scouting personnel are associated with higher toxicity applied to peanuts.

description: When environmental quality enters random utility models linearly, welfare measures are convex in quality. The convexity is partly due to site substitution, and it has policy implications for whether changes in quality should be concentrated or diffuse. These functional form effects are illustrated in a model of Great Lakes fishing.

description: We report extensive VLA and ATCA observations of the two diffuse radio sources in the cluster of galaxies Abell 548b, which confirm their classification as relics. The two relics (named A and B) show similar flux density, extent, shape, polarization and spectral index and are located at projected distances of about 430 and 500 kpc from the cluster center, on the same side of the cluster's X-ray peak. On the basis of spectral indices of discrete radio sources embedded within the diffuse features, we have attempted to distinguish emission peaks of the diffuse sources from unrelated sources. We have found that both relics, in particular the B-relic, show possible fine structure, when observed at high resolution. Another diffuse source (named C) is detected close in projection to the cluster center. High-resolution images show that it contains two discrete radio sources and a diffuse component, which might be a candidate for a small relic source. The nature and properties of the diffuse radio sources are discussed. We conclude that they are likely related to the merger activity in the cluster.

Constraints on ultra-low-frequency gravitational waves with statistics of pulsar spin-down rates II: Mann-Whitney U test

description: We investigate gravitational waves with sub-nanoHz frequencies ($10^{-11}$ Hz $\lesssim f_{\rm GW} \lesssim 10^{-9}$ Hz) from the spatial distribution of the spin-down rates of milli-second pulsars. As we suggested in Yonemaru et al. 2018, gravitational waves from a single source induces the bias in the observed spin-down rates of pulsars depending on the relative direction between the source and pulsar. To improve the constraints on the time derivative of gravitational-wave amplitude obtained in our previous work (Kumamoto et al. 2019), we adopt a more sophisticated statistical method called the Mann-Whitney U test. Applying our method to the ATNF pulsar catalogue, we first found that the current data set is consistent with no GW signal from any direction in the sky. Then, we estimate the effective angular resolution of our method to be $(66~{\rm deg})^2$ by studying the probability distribution of the test statistic. Finally, we investigate gravitational-wave signal from the Galactic Centre and M87 and, comparing simulated mock data sets with the real pulsar data, we obtain the upper bounds on the time derivative as $\dot{h}_{\rm GC} < 8.9 \times 10^{-19} {\rm s}^{-1}$ for the Galactic Centre and $\dot{h}_{\rm M87} < 3.3 \times 10^{-19} {\rm s}^{-1}$ for M87, which are stronger than the ones obtained in Kumamoto et al. 2019 by factors of 7 and 25, respectively.
