subject: beef
subject: willingness to pay.

description: This paper analysed factors contributing to consumers’ willingness to pay (WTP) for increased quality information. The empirical scope of the study was restricted to beef, because the beef labelling system enables reliable tracing of quality attributes. The results showed that consumer perceptions of specific risks in food partly explain their WTP. Also negative experiences heard from other people increased the probability of WTP. Trust seems to be extremely significant factor in WTP models. This study implies that the majority of the respondents trust the food safety authorities and the co‐operation of all stakeholders in the food chain.
The face of achievement : influences on teacher decision making about aboriginal students
Creators: name: Riley, Tasha Anastasia
Publisher: name: University of British Columbia
Year: 2009

description: In British Columbia, the issue of low graduation rates among Aboriginal students has been addressed often. Some researchers have claimed that racism is a factor that impedes the progress of Aboriginal students. Since teachers' decisions potentially have a profound impact upon students, this study investigated whether teachers discriminate when they make decisions about students. Fifty pre-service teachers recommended 24 fictional students for remedial, average or advanced programs based upon the program eligibility criteria. Results indicated that students whom teachers were led to believe were of Aboriginal ancestry and students whom they were led to believe were students for whom English was a second language were consistently under-rated in comparison to their non-Aboriginal counterparts regardless of the students' prior academic record.

description: The paper considers the relationship between trust and governance structure from a Transaction Cost Economics perspective. The role of trust in the coordinating decisions is variously conceptualized according to the theoretical view adopted by the scholars. The present study adopt the three‐level schema introduced by Williamson (1996) and suggest that determinants of trust may operate both at institutional and governance structure level. The analytical framework depicted maintains that trust may determine a reduction of ex post transaction cost in the adaptation of hybrid structure. As a consequence trust appears to be able to extend the range of existence of the hybrids. The empirical part of the study is dedicated to a case study which illustrates the emerging of conditional trust (Fritz et al., 2008) and the role of trust in the adaptation process.

description: The Federal Government of Germany as well as the European Commission are discussing the establishment of an animal welfare label. This label should enable consumers to make a conscious purchasing decision on animal welfare products. Various studies show that many consumers (in Germany around 20 %) prefer products produced under animal friendly conditions. However, the supply of such products is limited. The following study examines the source of this discrepancy by way of an action‐based analytical approach and identifies different barriers within the supply chain that prevent the establishment of a market segment for animal welfare products. Although consumer demand will be decisive for long‐term success, first of all the stakeholders of the supply chain must be convinced. If the stakeholders are not prepared to participate in an animal welfare program the diffusion phase can take a very long time or even fail. This study presents such supply chain barriers and interprets them in the light of neoinstitutionalism.
Transverse excitations of ultracold matter waves upon propagation past abrupt waveguide changes

description: The propagation of ultracold atomic gases through abruptly changing waveguide potentials is examined in the limit of non-interacting atoms. Time-independent scattering calculations of microstructured waveguides with discontinuous changes in the transverse harmonic binding potentials are used to mimic waveguide perturbations and imperfections. Three basic configurations are examined: step-like, barrier-like and well-like with waves incident in the ground mode. At low energies, the spectra rapidly depart from single-moded, with significant transmission and reflection of excited modes. The high-energy limit sees 100 percent transmission, with the distribution of the transmitted modes determined simply by the overlap of the mode wave functions and interference.

description: Coexistence between cellular systems and Wi-Fi gained the attention of the research community when LTE License Assisted Access (LAA) entered the unlicensed band. The recent introduction of NR-U as part of 5G introduces new coexistence opportunities because it implements scalable numerology (flexible subcarrier spacing and OFDM symbol lengths), and non-slot based scheduling (mini-slots), which considerably impact channel access. This paper analyzes the impact of NR-U settings on its coexistence with Wi-Fi networks and compares it with LAA operation using simulations and experiments. First, we propose a downlink channel access simulation model, which addresses the problem of the dependency and non-uniformity of transmission attempts of different nodes, as a result of the synchronization mechanism introduced by NR-U. Second, we validate the accuracy of the proposed model using FPGA-based LAA, NR-U, and Wi-Fi prototypes with over-the-air transmissions. Additionally, we show that replacing LAA with NR-U would not only allow to overcome the problem of bandwidth wastage caused by reservation signals but also, in some cases, to preserve fairness in channel access for both scheduled and random-access systems. Finally, we conclude that fair coexistence of the aforementioned systems in unlicensed bands is not guaranteed in general, and novel mechanisms are necessary for improving the sharing of resources between scheduled and contention-based technologies.

description: In this paper, estimates of the impacts of various factors on the refrigerated OJ sales in Wal-Mart (WM) stores are presented. Data on WM stores, as well as grocery stores doing $2 million or greater annual business, across 52 Nielsen city markets (including the remaining U.S.) were studied. Since WM does not have stores in San Diego, this market was omitted. Weekly data for each city from week ending 3/11/06 through 3/01/08 (104 weeks) were included in the analysis. The relationship between WM refrigerated OJ dollar sales per store and 1) WM and $2million store prices, $2 million store promotions, a dummy variable to test whether sales may spike during periods when some consumers receive their paychecks (middle or end of the month), the number of same and new WM stores in the city, and seasonality variables, were studied.
Spin systems with dimerized ground states

description: In view of the numerous examples in the literature it is attempted to outline a theory of Heisenberg spin systems possessing dimerized ground states (``DGS systems") which comprises all known examples. Whereas classical DGS systems can be completely characterized, it was only possible to provide necessary or sufficient conditions for the quantum case. First, for all DGS systems the interaction between the dimers must be balanced in a certain sense. Moreover, one can identify four special classes of DGS systems: (i) Uniform pyramids, (ii) systems close to isolated dimer systems, (iii) classical DGS systems, and (iv), in the case of $s=1/2$, systems of two dimers satisfying four inequalities. Geometrically, the set of all DGS systems may be visualized as a convex cone in the linear space of all exchange constants. Hence one can generate new examples of DGS systems by positive linear combinations of examples from the above four classes.

One finds C_2^theory = 0.27 in agreement with the model-independent analysis of the experimental data from HERA on deep-inelastic electron scattering.

description: Graphane is a quasi-two-dimensional material consisting of a single layer of fully hydrogenated graphene, with a C:H ratio of 1. We study nuclear quantum effects in the so-called chair-graphane by using path-integral molecular dynamics (PIMD) simulations. The interatomic interactions are modeled by a tight-binding potential model fitted to density-functional calculations. Finite-temperature properties are studied in the range from 50 to 1500~K. To assess the magnitude of nuclear quantum effects in the properties of graphane, classical molecular dynamics simulations have been also performed. These quantum effects are significant in structural properties such as interatomic distances and layer area at finite temperatures. The in-plane compressibility of graphane is found to be about twice larger than that of graphene, and at low temperature it is 9\% higher than the classical calculation. The thermal expansion coefficient resulting from PIMD simulations vanishes in the zero-temperature limit, in agreement with the third law of Thermodynamics.

description: Pulsar timing experiments typically generate a phase-connected timing solution from a sequence of times-of-arrival (TOAs) by absolute pulse numbering, i.e. by fitting an integer number of pulses between TOAs in order to minimize the residuals with respect to a parametrized phase model. In this observing mode, rotational glitches are discovered, when the residuals of the no-glitch phase model diverge after some epoch, and glitch parameters are refined by Bayesian follow-up. Here an alternative, complementary approach is presented which tracks the pulse frequency $f$ and its time derivative $df/dt$ with a hidden Markov model (HMM), whose dynamics include stochastic spin wandering (timing noise) and impulsive jumps in $f$ and $df/dt$ (glitches). The HMM tracks spin wandering explicitly, as a specific realization of a discrete-time Markov chain. It discovers glitches by comparing the Bayes factor for glitch and no-glitch models. It ingests standard TOAs for convenience and, being fully automated, allows performance bounds to be calculated quickly via Monte Carlo simulations. Practical, user-oriented plots are presented of the false alarm probability and detection threshold (e.g. minimum resolvable glitch size) versus observational scheduling parameters (e.g. TOA uncertainty, mean delay between TOAs) and glitch parameters (e.g. transient and permanent jump sizes, exponential recovery time-scale). The HMM is also applied to $\sim 1$ yr of real data bracketing the 2016 December 12 glitch in PSR J0835-4510 as a proof of principle. It detects the known glitch and confirms that no other glitch exists in the same data with size $> 10^{-7} f$.

description: In this study, an OJ model was developed to examine the optimal advertising-research mix to maximize Florida grower revenue net of the costs of these activities. The model is based on assumed coefficients reflecting the impacts of prices, advertising and research. The effects of prices on demand and supply, as well as the effect of advertising on demand, were set based on findings of prior studies. The effect of research on supply is less certain, and a range of research effects was considered. A range of advertising effects was also considered given the study’s focus. The model solutions for the various advertising and research assumptions considered indicate that optimal advertising expenditures are significant

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We show how all non-MHV tree-level amplitudes in 0 =< N =< 4 gauge theories can be obtained directly from the known MHV amplitudes using the scalar graph approach of Cachazo, Svrcek and Witten. Generic amplitudes are given by sums of inequivalent scalar diagrams with MHV vertices. The novel feature of our method is that after the `Feynman rules' for scalar diagrams are used, together with a particular choice of the reference spinor, no further helicity-spinor algebra is required to convert the results into a numerically usable form. Expressions for all relevant individual diagrams are free of singularities at generic phase space points, and amplitudes are manifestly Lorentz- (and gauge-) invariant. To illustrate the method, we derive expressions for n-point amplitudes with three negative helicities carried by fermions and/or gluons. We also write down a supersymmetric expression based on Nair's supervertex which gives rise to all such amplitudes in 0 =< N =< 4 gauge theories.

description: In this paper, we consider the detection of a decrease of engagement by users spontaneously interacting with a socially assistive robot in a public space. We first describe the UE-HRI dataset that collects spontaneous Human-Robot Interactions following the guidelines provided by the Affective Computing research community to collect data "in-the-wild". We then analyze the users' behaviors, focusing on proxemics, gaze, head motion, facial expressions and speech during interactions with the robot. Finally, we investigate the use of deep learning techniques (Recurrent and Deep Neural Networks) to detect user engagement decrease in realtime. The results of this work highlight, in particular, the relevance of taking into account the temporal dynamics of a user's behavior. Allowing 1 to 2 seconds as buffer delay improves the performance of taking a decision on user engagement.

description: The cross-section and time series model used in this study yielded a number of important estimates for OJ and GJ demand. The own- and cross-price elasticities were, in general, similar to those found in past studies. The dummy variable estimates to control for city size, seasonality and other city specific trends appear reasonable, suggesting this modeling approach, and perhaps other variants, is useful for analyzing combined city data over time. The promotional estimates of the study support previous findings that featuring and displays significantly increase demand. Features and displays together have the largest impact. Price discounts have the smaller impacts but their magnitudes are larger than found in previous studies. Finally, although both the OJ and GJ promotional impacts were relatively large, those for GJ were larger than those for OJ.

description: We study a simple model of spin network evolution motivated by the hypothesis that the emergence of classical space-time from a discrete microscopic dynamics may be a self-organized critical process. Self organized critical systems are statistical systems that naturally evolve without fine tuning to critical states in which correlation functions are scale invariant. We study several rules for evolution of frozen spin networks in which the spins labelling the edges evolve on a fixed graph. We find evidence for a set of rules which behaves analogously to sand pile models in which a critical state emerges without fine tuning, in which some correlation functions become scale invariant.

description: We introduce a spatial stochastic process on the lattice Z^d to model mass extinctions. Each site of the lattice may host a flock of up to N individuals. Each individual may give birth to a new individual at the same site at rate ϕuntil the maximum of N individuals has been reached at the site. Once the flock reaches N individuals, then, and only then, it starts giving birth on each of the 2d neighboring sites at rate λ(N). Finally, disaster strikes at rate 1, that is, the whole flock disappears. Our model shows that, at least in theory, there is a critical maximum flock size above which a species is certain to disappear and below which it may survive.

description: We present an analytic solution of a simple set of equations that govern the expansion of boost-invariant plasmas of massless particles. These equations describe, approximately, the early time, collisionless regime, and the transition to hydrodynamics at late time. Their mathematical structure encompasses all versions of second order hydrodynamics when applied to Bjorken flows. The analytic solution provides an explicit expression for the attractor solution that connects the collisionless regime to hydrodynamics. It also constitutes a neat example of an application of the theory of resurgence in asymptotic series.

description: Estimates of a conditional demand system for twelve beverages, based on the Rotterdam model subject to a full, first-order autoregressive process, are discussed. Impacts of beverage prices, total beverage expenditures and promotions on beverage quantities demanded are provided. The results indicate that all beverages were normal goods; the majority had price elastic demands; most had a relatively large own-promotion effect; and a number of significant cross-promotional effects exist, indicating a relatively high level of competition for market share among the beverages studied.

Multipole invariants and non-Gaussianity
Creators: name: Land, Kate

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We propose a framework for separating the information contained in the CMB multipoles, $a_{\ell m}$, into its algebraically independent components. Thus we cleanly separate information pertaining to the power spectrum, non-Gaussianity and preferred axis effects. The formalism builds upon the recently proposed multipole vectors (Copi, Huterer & Starkman 2003; Schwarz & al 2004; Katz & Weeks 2004), and we elucidate a few features regarding these vectors, namely their lack of statistical independence for a Gaussian random process. In a few cases we explicitly relate our proposed invariants to components of the $n$-point correlation function (power spectrum, bispectrum). We find the invariants' distributions using a mixture of analytical and numerical methods. We also evaluate them for the co-added WMAP first year map.
Massive HI clouds with no optical counterparts as high-density regions of intragroup HI rings and arcs

description: We present a new scenario in which massive intragroup HI clouds are the high-density parts of large HI rings/arcs formed by dynamical interaction between galaxy groups and gas-rich, low surface brightness (LSB) galaxies with extended gas disks. Our hydrodynamical simulations demonstrate that the group tidal field is very efficient at stripping the outer HI gas of the disk if the gaseous disk of the LSB galaxy extends $2 - 5$ times further than the stellar disk. We find that a massive, extended `leading stream' orbiting the group's center can form out of the stripped outer HI envelope, while the severely shrunk LSB galaxy, whose stellar disk remains unaffected, continues on its path. The result is a relatively isolated, massive HI cloud with a ring- or arc-like shape, a very inhomogeneous density distribution ($N_{\rm HI} \sim 1.0 \times 10^{17} - 1.1 \times 10^{20}$ atoms cm$^{-2}$), and, initially, no stellar content. Only the high density peaks of the simulated intragroup HI ring/arc can be detected in many current HI observations. These will appear as relatively isolated `HI islands' near the group center. We also find that star formation can occur within the ring/arc, if the total gas mass within the intragroup ring/arc is very large ($\sim$ 4 $\times$ $10^9$ ${\rm M}_{\odot}$). We discuss these results in terms of existing observations of intragroup gas (e.g., the Leo Ring and HIPASS J0731--69) and intergalactic HII regions.

description: We construct slowly rotating black-hole solutions of Einsteinian cubic gravity (ECG) in four dimensions with flat and AdS asymptotes. At leading order in the rotation parameter, the only modification with respect to the static case is the appearance of a non-vanishing $g_{tϕ}$ component. Similarly to the static case, the order of the equation determining such component can be reduced twice, giving rise to a second-order differential equation which can be easily solved numerically as a function of the ECG coupling. We study how various physical properties of the solutions are modified with respect to the Einstein gravity case, including its angular velocity, photon sphere, photon rings, shadow, and innermost stable circular orbits (in the case of timelike geodesics).

Beyond guilt, shame, and blame to compassion, respect and empowerment : young aboriginal mothers and the first nations and inuit fetal alcohol syndrome/fetal alcohol effects initiative
Creators: name: Salmon, Amy

description: Over the past decade, the "problem" of Fetal Alcohol Syndrome and Fetal Alcohol Effects among Aboriginal peoples has received increasing attention from the Canadian nation-state. However, few feminist, anti-racist, anti-ableist, and anti-colonial scholars have offered a critique of FAS/E "prevention" policies aimed at Aboriginal women. In this dissertation, I present my analysis of the "official knowledge" and "public pedagogies" articulated in one such policy, The First Nations and Inuit Fetal Alcohol Syndrome/ Fetal Alcohol Effects Initiative (herein "the Initiative"). This analysis unravels the complex and contradictory tensions in contemporary state policy formation. My findings show how the Initiative paradoxically supports the development of inclusive, grassroots approaches to FAS/E prevention in Aboriginal communities while at the same time eclipsing the voices and concerns of Aboriginal women. Though neglected in the official policy texts and talk of the Initiative, young Aboriginal mothers' agency and insights are central in the dialectic of ideology, discourse, and lived experience that this study documents. To facilitate this shift, I engage a productive methodological synthesis of textual analysis, institutional ethnography, and participatory research, by grounding my analysis of the texts in indepth group interviews with six Aboriginal mothers whose lives include substance use and FAS/E. This study offers significant implications for the development of future policy, research, and "culturally appropriate" pedagogy for and about FAS/E "prevention". My findings do not support the outright rejection of medical models of disability, as has been favoured by many critical theorists and activists on the grounds that such models are universally oppressive and disenfranchising. Rather, the women's insights into their own lived experiences emphasize the simultaneously enabling and disabling consequences of medicalization. Accordingly, my findings underscore the urgent need to reconsider the roles of "race", gender, class, nation and dis/ability in contemporary theories and practices of substantive citizenship and nation-building in and outside of education.
A theory for long-memory in supply and demand

description: Recent empirical studies have demonstrated long-memory in the signs of orders to buy or sell in financial markets [2, 19]. We show how this can be caused by delays in market clearing. Under the common practice of order splitting, large orders are broken up into pieces and executed incrementally. If the size of such large orders is power law distributed, this gives rise to power law decaying autocorrelations in the signs of executed orders. More specifically, we show that if the cumulative distribution of large orders of volume v is proportional to v to the power -alpha and the size of executed orders is constant, the autocorrelation of order signs as a function of the lag tau is asymptotically proportional to tau to the power -(alpha - 1). This is a long-memory process when alpha < 2. With a few caveats, this gives a good match to the data. A version of the model also shows long-memory fluctuations in order execution rates, which may be relevant for explaining the long-memory of price diffusion rates.

Power and interests at work : a study of therapeutic recreation program planning in residential care
Creators: name: Murphy, Janice
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to develop a deeper understanding of how and why therapeutic recreation (TR) programs are planned in an extended care residential facility and the influence of the context, power and interests on planning. The TR literature does not adequately address the complex context of TR planning practice in residential care and does not help recreation therapists (RTs) understand how to ethically navigate through the power and interests that influence planning. A combination of qualitative research methods including interviews, observations and document analysis were used in this case study, located in the Fraser Valley, British Columbia, Canada. Practicing RTs and their TR Manager were interviewed two to three times each. Three monthly planning meetings and one TR business meeting were observed and recorded and one TR job action planning meeting was recorded. The RTs held strong beliefs about the purpose of TR and its role in contributing to the quality of life of people living in residential care. Organizational, professional, and personal power and interests influenced RTs' planning practice and were important factors in the RTs program planning decisions, whom they involved in making those decisions and thus whose interests were served. The impact of other stakeholders on the RTs planning practice was evident in the study. To competently engage in the sociopolitical activities of planning, the RTs were aware of who was involved in their planning practice (e.g., nurses, care aides, housekeepers, food service workers, volunteers, and family members) and who should be involved more (e.g., isolated and lower cognitive functioning residents). In addition, the RTs utilized several definably different tactics in planning situations involving power issues. Depending upon the circumstances, the power of the stakeholder and the personal style of the individual, the RTs engaged in reasoning, consulting, networking^ appealing, bargaining, counteracting and pressuring. Incorporating the concepts and theories about planning from the adult education literature, a more robust question-based framework for TR is suggested that applies the contextual, sociopolitical and ethical elements of planning to the richly technical and theoretical Leisure Ability Model. Recommendations for practice and for further research are offered.
