How can I help you? : the role of recommendation agents in collaborative online shopping
Creators: name: Huang, Shan
Publisher: name: University of British Columbia
Year: 2016

description: This research examines two important, understudied questions: whether or not recommendation agents (RAs) assist collaborative online shopping (COS), in which two or more shoppers communicate directly and synchronously, and whether or not this depends on how restrictively the RA provides its service. Results from a laboratory experiment show that compared to the use of no RA or a restrictive RA, the use of a flexible RA leads to higher perceived shopping enjoyment (hedonic value). Compared to the use of no RA, the use of a flexible RA or a restrictive RA is associated with higher perceptions of usefulness. However, no difference was found among the three conditions (no RA, flexible RA, and restrictive RA) in terms of perceived purchase decision quality (utilitarian value), nor did restrictiveness significantly affect perceived usefulness. To look beneath the surface of these results, I examined protocols of the social interactions that took place during the task and I analyzed them with Interaction Process Analysis (IPA). The results suggest that flexible RAs were preferred over no RAs or restrictive RAs because they strike a balance between leadership and empowerment during the social encounter.

description: In our continued efforts of matching full string computations with the corresponding effective field theory computations, we evaluate string theory correlators in closed forms. In particular, we consider a correlator between three SYM vertex operators and one Ramond-Ramond $C$-field vertex operator: $$. We show that the infinite number of massless poles of this amplitude can be reproduced by the Born-Infeld action, the Wess-Zumino terms, and their higher derivative corrections. More specifically we find, up to an on-shell ambiguity, two scalar field and two gauge field couplings to all orders in $α'$ such that the infinite number of massless poles of the field theory amplitude exactly match the infinite number of massless poles of S-matrix elements of $$. We comment on close intertwinedness of an open string and a closed string that must be behind the matching.

description: In a previous paper, we defined a space-level version X(L) of Khovanov homology. This induces an action of the Steenrod algebra on Khovanov homology. In this paper, we describe the first interesting operation, Sq^2:Kh^{i,j}(L) -> Kh^{i+2,j}(L). We compute this operation for all links up to 11 crossings; this, in turn, determines the stable homotopy type of X(L) for all such links.

NIMASTEP: a software to modelize, study and analyze the dynamics of various small objects orbiting specific bodies

description: NIMASTEP is a dedicated numerical software developed by us, which allows one to integrate the osculating motion (using cartesian coordinates) in a Newtonian approach of an object considered as a point-mass orbiting a homogeneous central body that rotates with a constant rate around its axis of smallest inertia. The code can be applied to objects such as particles, artificial or natural satellites or space debris. The central body can be either any terrestrial planet of the solar system, any dwarf-planet, or even an asteroid. In addition, very many perturbations can be taken into account, such as the combined third-body attraction of the Sun, the Moon, or the planets, the direct solar radiation pressure (with the central body shadow), the non-homogeneous gravitational field caused by the non-sphericity of the central body, and even some thrust forces. The simulations were performed using different integration algorithms. Two additional tools were integrated in the software package; the indicator of chaos MEGNO and the frequency analysis NAFF. NIMASTEP is designed in a flexible modular style and allows one to (de)select very many options without compromising the performance. It also allows one to easily add other possibilities of use. The code has been validated through several tests such as comparisons with numerical integrations made with other softwares or with semi-analytical and analytical studies. The various possibilities of NIMASTEP are described and explained and some tests of astrophysical interest are presented. At present, the code is proprietary but it will be released for use by the community in the near future. Information for contacting its authors and (in the near future) for obtaining the software are available on the web site http://www.fundp.ac.be/en/research/projects/page_view/10278201/

description: The H-2A Agricultural Guest Worker program allows U.S. agricultural employers to hire foreign workers on a temporary or seasonal basis. Many U.S. producers of labor-intensive commodities appear to be adjusting to tighter farm labor markets by employing H-2A workers. The program rapidly expanded over the last decade, increasing from 79,000 H-2A workers in 2010 to 258,000 in 2019. All sectors and most regions of the United States have experienced significant growth in H-2A employment, but the increase is most pronounced in sectors with high labor requirements and seasonal employment, i.e., fruit and tree nuts and vegetables and melons. H-2A growth is uneven across the United States with larger employment changes in the Southeast than in other regions. Farm labor contractors (brokers that directly employ farmworkers and lease their services to farms) account for a growing share of H-2A employment. This report explores how H-2A usage levels differ by agricultural sector, across geography, and the type of firm requesting the workers. The analyses in this study can provide a benchmark to measure future changes in H-2A labor use.

description: A study to analyze the appropriateness of use of antibacterials in acute wards of a tertiary care hospital in India and to identify areas for improvement. Non-interventional descriptive study where in patient antibacterial prescriptions were analyzed for their adherence to or deviation from the standard national treatment guidelines. The study was conducted in four wards, namely acute medical, acute surgical, intensive care unit (ICU) and family wards of a teaching hospital of western India, authorized a total of 1082 beds. In each of the four wards, the antibiotic treatment of infectious diseases was analyzed by follow up of inpatients, those who were prescribed antimicrobial agents (AMA), for a calendar month each in May, June, July and August 2018 respectively. Data recorded included the demographic data like age and sex, the clinical diagnosis, antibiotics administered to the patient during their stay in the hospital, the duration of antibiotic use, the duration of hospital stay, and the result of their treatment as cured/discharged/transferred out. The prescriptions were analyzed for appropriateness by checking their adherence to or deviation from the standard national guidelines. From the collective data of antibiotics prescribed in all the four acute wards, the top five antibiotics consumed from each acute ward were chosen to assess for appropriateness of use. A high percentage of appropriateness was observed for dose of antibiotic used. The main targets identified for improvement are duration of antimicrobial use, choice of drug for surgical prophylaxis and the definitive use of antimicrobial agents.
In Canada we trust? understanding ethno-racial variations in social and political trust
Creators: name: Hwang, Monica
Publisher: name: University of British Columbia
Year: 2013

description: This thesis considers ethno-racial differences in social and political trust, which leading scholars see as the two key dimensions of social cohesion in Canada. Although not directly addressing problems of prejudice and intolerance, the analysis relates to this same research tradition. I compare trust among eight ethno-racial groupings: British, French, “Canadians,” other Europeans, Aboriginal Peoples, visible minorities, mixed-origins respondents, and all others. Building from the concepts of “social distance” and “social boundaries,” I test three sets of factors for explaining ethno-racial differences in trust: (1) three ethno-cultural “markers” – religion, language, and immigration status; (2) two socioeconomic influences –education and income; and (3) two social engagement indicators – voluntary association activity and ethnic diversity of friendships. Models also include controls for region, age, and gender. Based on the 2008 General Social Survey Public Use Microdata file, findings indicate that a perspective employing concepts of social distance and social boundaries helps in understanding many, though not all, of the differences in trust across ethno-racial communities. The results show that, compared to more established groups like the British, the most culturally distinctive minorities – visible minorities, French, and Aboriginal Peoples – express less social trust. This is consistent with the interpretation that groups subjected to more social distance/social boundaries experiences are less likely to develop social trust. Nevertheless, these same groups, except for Aboriginal Peoples, exhibit relatively high political trust. The latter finding suggests that some minorities, when treated or perceived by others as different or distant from the “mainstream,” may see government agencies as defending their minority rights and interests against discrimination. Aboriginal Peoples are an exception in being the only minority grouping to express lower levels of both social and political trust. This underscores their unique position in Canada. Despite being the country’s original inhabitants, they have long endured processes of discrimination, exclusion, and racism that understandably contribute to lower trust in other people. At the same time, historical and present-day governments have ignored, exacerbated, or created many of these injustices, giving Aboriginal Peoples far less reason than other groups to trust Canadian political institutions.

description: Die verstärkte Nutzung von Wärmepumpen ist eine wichtige Maßnahme zur Senkung der CO2-Emissionen im Wärmesektor. Zudem können Wärmepumpen dazu beitragen, die Importe von Erdgas zu reduzieren. Mit Hilfe eines Stromsektormodells werden die Auswirkungen eines beschleunigten Ausbaus von Wärmepumpen auf den deutschen Stromsektor untersucht. Knapp sechs Millionen zusätzliche Wärmepumpen würden den Strombedarf im Jahr 2030 um neun Prozent erhöhen. Um diesen mit Solarenergie zu decken, wäre eine Erweiterung der Photovoltaik-Kapazitäten um 23 Prozent notwendig. Die Erdgasimporte könnten dadurch um 15 Prozent gesenkt werden. Aus gesamtwirtschaftlicher Sicht wird eine deutlich stärkere Nutzung von Wärmepumpen immer vorteilhafter, je höher der Erdgaspreis ist. Ein schneller Umstieg auf Wärmepumpen erfordert allerdings die Unterstützung durch ein ambitioniertes und koordiniertes Programm der Politik, das auch den Ausbau von Produktionskapazitäten für Wärmepumpen und die Qualifizierung von Fachkräften im Blick hat – eine Art „Apollo-Programm“ für Wärmepumpen.

description: We study neutrino mass generation in models with four chiral families of leptons and quarks and four right handed neutrinos. Generically, in these models there are three different contributions to the light neutrino masses: the usual see-saw contribution, the tree-level contribution due to mixing of light neutrinos with neutrino of the fourth generation, and the two loop contribution due to the Majorana mass term of the fourth neutrino. We study properties of these contributions and their experimental bounds. The regions of the parameters (mixings of the fourth neutrino, masses of RH neutrino components, etc.) have been identified where various contributions dominate. New possibilities of a realization of the flavour symmetries in the four family context are explored. In particular, we consider applications of the smallest groups, e.g. SG(20,3), with irreducible representation 4.

description: The primordial velocity dispersion of dark matter is small compared to the velocities attained during structure formation. The initial density distribution is close to uniform and it occupies an initial sheet in phase space that is single valued in velocity space. Because of gravitational forces this three dimensional manifold evolves in phase space without ever tearing, conserving phase-space volume and preserving the connectivity of nearby points. N-body simulations already follow the motion of this sheet in phase space. This fact can be used to extract full fine-grained phase-space-structure information from existing cosmological N-body simulations. Particles are considered as the vertices of an unstructured three dimensional mesh, moving in six dimensional phase-space. On this mesh, mass density and momentum are uniquely defined. We show how to obtain the space density of the fluid, detect caustics, and count the number of streams as well as their individual contributions to any point in configuration-space. We calculate the bulk velocity, local velocity dispersions, and densities from the sheet - all without averaging over control volumes. This gives a wealth of new information about dark matter fluid flow which had previously been thought of as inaccessible to N-body simulations. We outline how this mapping may be used to create new accurate collisionless fluid simulation codes that may be able to overcome the sparse sampling and unphysical two-body effects that plague current N-body techniques.

description: We introduce N-extended (p,q) AdS superspaces in three space-time dimensions, with p+q=N and p>=q, and analyse their geometry. We show that all (p,q) AdS superspaces with X^{IJKL}=0 are conformally flat. Nonlinear sigma-models with (p,q) AdS supersymmetry exist for p+q<=4 (for N>4 the target space geometries are highly restricted). Here we concentrate on studying off-shell N=3 supersymmetric sigma-models in AdS_3. For each of the cases (3,0) and (2,1), we give three different realisations of the supersymmetric action. We show that (3,0) AdS supersymmetry requires the sigma-model to be superconformal, and hence the corresponding target space is a hyperkahler cone. In the case of (2,1) AdS supersymmetry, the sigma-model target space must be a non-compact hyperkahler manifold endowed with a Killing vector field which generates an SO(2) group of rotations of the two-sphere of complex structures.

description: It has been suggested in arXiv:1010.1415 that certain derivatively coupled non-renormalizable scalar field theories might restore the perturbative unitarity of high energy hard scatterings by classicalization, i.e. formation of multiparticle states of soft quanta. Here we apply the semiclassical method of calculating the multiparticle production rates to the scalar Dirac-Born-Infeld (DBI) theory which is suggested to classicalize. We find that the semiclassical method is applicable for the energies in the final state above the cutoff scale of the theory L_*^{-1}. We encounter that the cross section of the process two to N ceases to be exponentially suppressed for the particle number in the final state N smaller than a critical particle number N_{crit} ~ (E L_*)^{4/3}. It coincides with the typical particle number produced in two-particle collisions at high energies predicted by classicalization arguments.

description: Massive spectroscopic surveys of high-redshift quasars yield large numbers of correlated Lyman α absorption spectra that can be used to measure large-scale structure. Simulations of these surveys are required to accurately interpret the measurements of correlations and correct for systematic errors. An efficient method to generate mock realizations of Lyman α forest surveys is presented which generates a field over the lines of sight to the survey sources only, instead of having to generate it over the entire three-dimensional volume of the survey. The method can be calibrated to reproduce the power spectrum and one-point distribution function of the transmitted flux fraction, as well as the redshift evolution of these quantities, and is easily used for modeling any survey systematic effects. We present an example of how these mock surveys are applied to predict the measurement errors in a survey with similar parameters as the BOSS quasar survey in SDSS-III.

To lag or not to lag? How to compare indices of stock markets that operate at different times
Creators: name: Junior, Leonidas Sandoval
Publisher: name: arXiv
Year: 2012
Subjects: subject: General Finance (q-fin.GN)
subject: FOS: Economics and business

description: Financial markets worldwide do not have the same working hours. As a consequence, the study of correlation or causality between financial market indices becomes dependent on wether we should consider in computations of correlation matrices all indices in the same day or lagged indices. The answer this article proposes is that we should consider both. In this work, we use 79 indices of a diversity of stock markets across the world in order to study their correlation structure, and discover that representing in the same network original and lagged indices, we obtain a better understanding of how indices that operate at different hours relate to each other.
A model and analysis of two-handed interaction with a keyboard and pointing device
Creators: name: Link, Juliette Frances
Publisher: name: University of British Columbia
Year: 2013

description: The benefits of two-handed interaction have been heavily researched and new input devices that presumably better support such interaction are common. Yet the standard desktop setup today continues to be a keyboard and pointing device. Despite its universality, there does not exist a systematic description of two-handed interaction with this setup. Our work fills that gap. We conducted observational studies with 37 design application users focusing on three fundamental elements of two-handed interaction: (1) the configurations hands assume (the different positions the two hands are in relative to the input devices), (2) how much time is spent in each configuration, and (3) how often the hands move between the configurations. We propose a model that describes the patterns of two-handed interaction that occur broadly across all users, for example that every user had a configuration in which s/he spent the majority of his or her time (for most users this was one hand on the left side of the keyboard and one hand on the mouse). We also document where there are individual differences in patterns, namely in how much each hand moves. The three-staged analytic approach we took to arrive at these findings is described, along with implications for design.

So sollte Druck auf den Kreml ausgeübt werden, zunächst die Verlegung von Truppen in die Regionen Donezk und Luhansk und schließlich den Angriff auf die Ukraine zu beenden. Der vorliegende Bericht untersucht, wie sich diese Sanktionen auf Unternehmen auswirken, die von russischen OligarchInnen geleitet werden. Die empirischen Befunde zeigen, dass die Aktienrenditen von Unternehmen mit sanktionierten OligarchInnen im Vorstand nach der Ankündigung der Sanktionen deutlich unter den Aktienrenditen von Unternehmen ohne sanktionierte Vorstände lagen. Beispielsweise dürften InvestorInnen aufgrund von Signaleffekten sowie rechtlichen und wirtschaftlichen Unsicherheiten negative Folgen für Unternehmen mit betroffenen OligarchInnen erwarten und sich deshalb zurückziehen. Persönliche Sanktionen können also über die negativen Effekte auf Unternehmenswerte einen gewissen ökonomischen Druck ausüben.

description: Spectroscopic Analyses of Photoconversion in Phytochromes

Phytochrome photoreceptors integrate red and far-red light to inform vital adaptations of physiology, development, and lifestyle in manifold plants, bacteria, and fungi. Once covalently assembled with bilin chromophores, phytochromes traverse their metastable Pr and Pfr states depending on light quality and intensity. This chapter provides protocols for the analyses of phytochromes by absorption spectroscopy to determine their molar extinction coefficients; their photostationary state assumed under constant illumination; and their quantum yields for the light-driven Pr⇄Pfr interconversion. Knowledge of these parameters pertains to the natural role of phytochromes and their deployment in optogenetics and biotechnology.

We model these intense laser beams as finite length plane-wave-fronted pulses, similar to Neville and Rohrlich [Phys. Rev. D {\bf 3}, 1692 (1971)], or as trains of such pulses. Expressions for energy and angular distributions of Compton photons are derived such that a comparison of both situations becomes meaningful. Comparing frequency distributions for both an isolated laser pulse and a laser pulse train, we find a very good agreement between the results for long pulse durations which breaks down however for ultrashort laser pulses. The dependence of angular distributions of emitted radiation on a pulse duration is also investigated. Pronounced asymmetries of angular distributions are found for very short laser pulses, which gradually disappear with increasing the number of laser field oscillations. Those asymmetries are attributed to asymmetries of the vector potential describing an incident laser beam.

Zone-Center Dynamical Matrix in Magnetoelectrics

description: In ordinary dielectrics the dynamical matrix at the zone center in general is a nonanalytic function of degree zero in the wavevector q. Its expression (for a crystal of arbitrary symmetry) is well known and is routinely implemented in first principle calculations. The nonanalytic behavior occurs in polar crystals and owes to the coupling of the macroscopic electric field E to the lattice. In magnetoelectric crystals both electric and magnetic fields, E and H, are coupled to the lattice, formally on equal footing. We provide the general expression for the zone center dynamical matrix in a magnetoelectric, where the E and H couplings are accounted for in a symmetric way. As in the ordinary case, the dynamical matrix is a nonanalytic function of degree zero in q, and is exact in the harmonic approximation. For the sake of completeness, we address other issues, and in particular we solve a problem which might arise in first-principle implementations, where-differently than here-the basic fields are E and B (not H).

description: We report scanning tunneling microscopy (STM) and spectroscopy (STS) of twisted graphene bilayer on SiC substrate. For twist angle ~ 4.5o the Dirac point ED is located about 0.40 eV below the Fermi level EF due to the electron doping at the graphene/SiC interface. We observed an unexpected result that the local Dirac point around a nanoscaled defect shifts towards the Fermi energy during the STS measurements (with a time scale about 100 seconds). This behavior was attributed to the decoupling between the twisted graphene and the substrate during the measurements, which lowers the carrier density of graphene simultaneously.

Scale dependent halo bias in the excursion set approach

description: If one accounts for correlations between scales, then nonlocal, k-dependent halo bias is part and parcel of the excursion set approach, and hence of halo model predictions for galaxy bias. We present an analysis that distinguishes between a number of different effects, each one of which contributes to scale-dependent bias in real space. We show how to isolate these effects and remove the scale dependence, order by order, by cross-correlating the halo field with suitably transformed versions of the mass field. These transformations may be thought of as simple one-point, two-scale measurements that allow one to estimate quantities which are usually constrained using n-point statistics. As part of our analysis, we present a simple analytic approximation for the first crossing distribution of walks with correlated steps which are constrained to pass through a specified point, and demonstrate its accuracy. Although we concentrate on nonlinear, nonlocal bias with respect to a Gaussian random field, we show how to generalize our analysis to more general fields.

description: This is a theoretical review of exploration of new physics beyond the Standard Model (SM) in electric dipole moment (EDM) in elementary particles, atoms, and molecule. EDM is a very important CP violating phenomenon and sensitive to new physics. Starting with the estimations of EDM of quarks-leptons in the SM, we explore the new signals beyond the SM. However, these works drive us to more wide fronteers where we serach fundamental physics using atoms and molecules and vice versa. Paramagnetic atoms and molecules have great enhancement factor on electron EDM. Diamagnetic atoms and molecules are very sensitive to nuclear P and T odd processes. Thus the EDM becomes the key word not only of New Physics but also of unprecedented fruitful collaboration among particle, atomic. molecular physics. This review intends to help such collaboration over the wide range of physicists.

description: This paper studies iteration convergence of Kronecker graphical lasso (KGLasso) algorithms for estimating the covariance of an i.i.d. Gaussian random sample under a sparse Kronecker-product covariance model and MSE convergence rates. The KGlasso model, originally called the transposable regularized covariance model by Allen ["Transposable regularized covariance models with an application to missing data imputation," Ann. Appl. Statist., vol. 4, no. 2, pp. 764-790, 2010], implements a pair of $\ell_1$ penalties on each Kronecker factor to enforce sparsity in the covariance estimator. The KGlasso algorithm generalizes Glasso, introduced by Yuan and Lin ["Model selection and estimation in the Gaussian graphical model," Biometrika, vol. 94, pp. 19-35, 2007] and Banerjee ["Model selection through sparse maximum likelihood estimation for multivariate Gaussian or binary data," J. Mach. Learn. Res., vol. 9, pp. 485-516, Mar. 2008], to estimate covariances having Kronecker product form. It also generalizes the unpenalized ML flip-flop (FF) algorithm of Dutilleul ["The MLE algorithm for the matrix normal distribution," J. Statist. Comput. Simul., vol. 64, pp. 105-123, 1999] and Werner ["On estimation of covariance matrices with Kronecker product structure," IEEE Trans. Signal Process., vol. 56, no. 2, pp. 478-491, Feb. 2008] to estimation of sparse Kronecker factors. We establish that the KGlasso iterates converge pointwise to a local maximum of the penalized likelihood function. We derive high dimensional rates of convergence to the true covariance as both the number of samples and the number of variables go to infinity. Our results establish that KGlasso has significantly faster asymptotic convergence than Glasso and FF. Simulations are presented that validate the results of our analysis.
