description: The paper explores the characteristics of spatial price dynamics for fresh vegetables. The analysis is carried out on selected EU prices for tomatoes and cauliflowers collected on some of the main production and consumption markets. It is based on the estimation of an time-varying threshold autoregressive econometric specification that is shown capable to underline the asymmetries in inter-Countries price transmission. The model shows that that horizontal price transmissions among net producer and net consumer markets is asymmetric and how such characteristic differs for markets closer to production areas or to consumption locations. This paper allowed to assess the average elapsing time for shocks to be transmitted among spatially separated markets, and, in particular, it shows the speed of transmission of price raises and price falls.

description: Los sistemas agroalimentarios locales (SIAL) de aceite de oliva en España son un buen ejemplo del comportamiento multifuncional y de su contribución potencial a la gobernanza territorial. Se detectan cambios significativos en la geografía del olivar español, derivados, por una parte, de la expansión de nuevas superficies de olivar en regadío de cultivo intensivo y superintensivo y, por otra, de la creciente marginalización a la que se ve abocado el olivar español de media y alta pendiente. Por otra parte, el olivar español produce un fuerte grado de externalidades ambientales negativas, como la erosión o la contaminación difusa de suelos y acuíferos. El principal objetivo del trabajo es detectar las relaciones que se establecen entre la definición de los principales problemas que atañen a los SIAL de aceite de oliva en España y las prioridades de investigación e innovación en materia de territorio y medio ambiente, desde una óptica multidisciplinar que integre enfoques procedentes de las Ciencias Sociales y de las Ciencias Agronómicas y Ambientales. El marco teórico procede de las teorías sobre la multifuncionalidad de los espacios rurales y sobre los SIAL. La metodología utiliza información cualitativa y cuantitativa procedente de dos fuentes primarias: i) un grupo de discusión integrado en un panel presencial de expertos sobre innovación en olivicultura, sostenibilidad y aprovechamiento de residuos; ii) un análisis Delphi dirigido a un conjunto amplio de expertos sobre medio ambiente, territorio y desarrollo rural sostenible en el sector oleícola. En cuanto al análisis de resultados, el grupo de discusión ha tenido como misión categorizar las grandes tipologías de olivicultura en España y sintetizar sus respectivos problemas ambientales y territoriales. Estos resultados sirven como marco de referencia del análisis Delphi, que tiene un doble objetivo: por una parte, el análisis de los principales problemas ambientales y territoriales de los SIAL oleícolas en España; por otra, el estudio de las prioridades en materia de programas y de grupos de líneas de investigación sobre la materia, así como las relaciones entre dichas líneas de investigación y los problemas a los que se enfrentan los SIAL oleícolas.
Japanese women writers watch a boy being beaten by his father : male homosexual fantasies, female sexuality and desire
Creators: name: Nagaike, Kazumi
Publisher: name: University of British Columbia
Year: 2009

description: This thesis discusses narrative texts by Japanese female writers and popular manga artists* that deal with fantasies of male-male sex. It applies a variety of psychoanalytic theories (Freudian, Kleinian, feminist and so forth) to demonstrate how fantasies about male homosexuality may be analyzed in terms of the psychological orientations of the many Japanese women who are the readers of this narrative genre. I also discuss a variety of themes that often accompany and appear to support female fantasies of male homosexuality: the concept of Thomme fatal' in Mori Mari's male homosexual trilogy; sadomasochism in Kono Taeko's "Toddler-Hunting"; the decadent aestheticism of Okamoto Kanoko's "The Bygone World'; postmodernism in Matsuura Rieko's The Reverse Version; and the concept of . pornography as it relates to yaoi manga. * * In attempting to analyze the discursive aspects of female fantasies of male homosexuality, I begin with an examination of Sigmund Freud's article, "A Child is Being Beaten," in which he refers to the female scoptophilic impulse. Several Japanese female writers—Kono Taeko, in particular—provide clear examples of narratives that parallel Freud's model of the beating fantasy. This female scoptophilic desire to watch a male homoerotic 'show' is activated by a psychological orientation such as that defined by Klein's model of projective identification: female characters and readers project their 'unbalanced egos' onto male homosexual characters, and this enhances the processes of identification with and (scoptophilic) dissociation from these characters—which in turn create the possibility of regaining psychological 'balance.' One of the main themes of my analysis is the development of subconscious female desires to access the bisexual (simultaneously masculine and feminine) body. I discuss the idealization of the shorten (boy) identity (in "Toddler-Hunting" and The Reverse Version) and the image of the 'reversible couple' in yaoi manga as specific forms of a sexual discourse that presents possibilities of escape from the arbitrary, socially-constructed, but institutionalized concepts of the female body. *manga: narrative comic books for readers of all ages **yaoi manga: a subgenre of comic books by and for women that feature male-male eroticism
The Physical Role of Gravitational and Gauge Degrees of Freedom in General Relativity - II: Dirac versus Bergmann observables and the Objectivity of Space-Time

description: (abridged)The achievements of the present work include: a) A clarification of the multiple definition given by Bergmann of the concept of {\it (Bergmann) observable. This clarification leads to the proposal of a {\it main conjecture} asserting the existence of i) special Dirac's observables which are also Bergmann's observables, ii) gauge variables that are coordinate independent (namely they behave like the tetradic scalar fields of the Newman-Penrose formalism). b) The analysis of the so-called {\it Hole} phenomenology in strict connection with the Hamiltonian treatment of the initial value problem in metric gravity for the class of Christoudoulou -Klainermann space-times, in which the temporal evolution is ruled by the {\it weak} ADM energy. It is crucial the re-interpretation of {\it active} diffeomorphisms as {\it passive and metric-dependent} dynamical symmetries of Einstein's equations, a re-interpretation which enables to disclose their (nearly unknown) connection to gauge transformations on-shell; this is expounded in the first paper (gr-qc/0403081). The use of the Bergmann-Komar {\it intrinsic pseudo-coordinates} allows to construct a {\it physical atlas} of 4-coordinate systems for the 4-dimensional {\it mathematical} manifold, in terms of the highly non-local degrees of freedom of the gravitational field (its four independent {\it Dirac observables}), and to realize the {\it physical individuation} of the points of space-time as {\it point-events} as a gauge-fixing problem, also associating a non-commutative structure to each 4-coordinate system.

Shrinkage priors for nonparametric Bayesian prediction of nonhomogeneous Poisson processes
Creators: name: Komaki, Fumiyasu
Publisher: name: arXiv
Year: 2020
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: We consider nonparametric Bayesian estimation and prediction for nonhomogeneous Poisson process models with unknown intensity functions. We propose a class of improper priors for intensity functions. Nonparametric Bayesian inference with kernel mixture based on the class improper priors is shown to be useful, although improper priors have not been widely used for nonparametric Bayes problems. Several theorems corresponding to those for finite-dimensional independent Poisson models hold for nonhomogeneous Poisson process models with infinite-dimensional parameter spaces. Bayesian estimation and prediction based on the improper priors are shown to be admissible under the Kullback--Leibler loss. Numerical methods for Bayesian inference based on the priors are investigated.

description: We report the results of a search for the decay modes B0 -> J/psi D0bar and B+ -> J/psi D0bar pi+. The analysis is based on 140 $\rm fb^{-1}$ of data accumulated by the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider. No significant signals are observed and we determine the branching fraction upper limits B(B0 -> J/psi D0bar) < 2.0 10^{-5} and B(B+ -> J/psi D0bar pi+) < 2.5 10^{-5} at 90% confidence level. These results rule out the explanation of the excess in the low momentum region of the inclusive J/psi spectrum as intrinsic charm content in the B meson. The branching fractions of the corresponding non-resonant decay channels are also reported.

description: Conversational AI agents are proliferating, embodying a range of devices such as smart speakers, smart displays, robots, cars, and more. We can envision a future where a personal conversational agent could migrate across different form factors and environments to always accompany and assist its user to support a far more continuous, personalized, and collaborative experience. This opens the question of what properties of a conversational AI agent migrates across forms, and how it would impact user perception. To explore this, we developed a Migratable AI system where a user's information and/or the agent's identity can be preserved as it migrates across form factors to help its user with a task. We designed a 2x2 between-subjects study to explore the effects of information migration and identity migration on user perceptions of trust, competence, likeability, and social presence. Our results suggest that identity migration had a positive effect on trust, competence, and social presence, while information migration had a positive effect on trust, competence, and likeability. Overall, users report the highest trust, competence, likeability, and social presence towards the conversational agent when both identity and information were migrated across embodiments.

description: We study the overdamped dynamics of a Brownian particle in the double-well potential under the influence of an external periodic (AC) force with zero mean. We obtain a dependence of the jump rate on the frequency of the external force. The dependence shows a maximum at a certain driving frequency. We explain the phenomenon as a switching between different time scales of the system: interwell relaxation time (the mean residence time) and the intrawell relaxation time. Dependence of the resonant peak on the system parameters, namely the amplitude of the driving force A and the noise strength (temperature) D has been explored. We observe that the effect is well pronounced when A/D > 1 and if A/D 1 the enhancement of the jump rate can be of the order of magnitude with respect to the Kramers rate.

description: Egypt's food subsidies (in 1996/97 5.5 percent of government expenditures or US$1.1 bn.) cover rationed oil and sugar (23 percent of subsidy cost) and unrationed bread and flour (77 percent). The subsidies enhance food security but are nontargeted and have substantial leakages. This paper uses a Computable General Equilibrium (CGE) model to simulate the short-run effects of alternative food- subsidy scenarios. Savings from reduced subsidy spending are used to reduce direct taxes uniformly for all household types. The model uses a 1996/97 database with detailed household information. The simulated impact of targeting or eliminating oil and sugar subsidies is small: disaggregated real household consumption changes by ±0.3 percent. It is progressive if the subsidy is targeted to "the needy" (the bottom two quintiles in rural and urban areas) and regressive if it is eliminated. The targeting of all food subsidies is pro-needy, in part due to important indirect effects. It raises the consumption of the needy by 0.5 percent with, on average, little change for the nonneedy. The strongest gains are recorded for the rural needy (consumption increase by 1.0 percent). Food subsidy elimination is regressive: the needy suffer a consumption loss of 1.1 percent. If the government savings instead are transferred to the needy, the impact is reversed: consumption increases by 4.2 percent for needy households while the nonneedy register a small loss. The overall policy implication of the paper is that there is scope for reducing food subsidy spending without hurting the low-income groups.

description: In quantum statistical mechanics, Moyal's equation governs the time evolution of Wigner functions and of more general Weyl symbols that represent the density matrix of arbitrary mixed states. A formal solution to Moyal's equation is given by Marinov's path integral. In this paper we demonstrate that this path integral can be regarded as the natural link between several conceptual, geometric, and dynamical issues in quantum mechanics. A unifying perspective is achieved by highlighting the pivotal role which the response field, one of the integration variables in Marinov's integral, plays for pure states even. The discussion focuses on how the integral's semiclassical approximation relates to its strictly classical limit; unlike for Feynman type path integrals, the latter is well defined in the Marinov case. The topics covered include a random force representation of Marinov's integral based upon the concept of "Airy averaging", a related discussion of positivity-violating Wigner functions describing tunneling processes, and the role of the response field in maintaining quantum coherence and enabling interference phenomena. The double slit experiment for electrons and the Bohm-Aharonov effect are analyzed as illustrative examples. Furthermore, a surprising relationship between the instantons of the Marinov path integral over an analytically continued ("Wick rotated") response field, and the complex instantons of Feynman-type integrals is found. The latter play a prominent role in recent work towards a Picard-Lefschetz theory applicable to oscillatory path integrals and the resurgence program.

description: A symplectic groupoid $G.:=(G_1 \rightrightarrows G_0)$ determines a Poisson structure on $G_0$. In this case, we call $G.$ a symplectic groupoid of the Poisson manifold $G_0$. However, not every Poisson manifold $M$ has such a symplectic groupoid. This keeps us away from some desirable goals: for example, establishing Morita equivalence in the category of all Poisson manifolds. In this paper, we construct symplectic Weinstein groupoids which provide a solution to the above problem (Theorem \ref{main}). More precisely, we show that a symplectic Weinstein groupoid induces a Poisson structure on its base manifold, and that to every Poisson manifold there is an associated symplectic Weinstein groupoid.

description: This paper has been prepared as part of the Zambia country study of the Macroeconomic and Regional Integration in Southern Africa (MERRISA) project and serves as a background paper for modeling exercises. The paper focuses on analyzing institutional constraints on the development of the agricultural sector in Zambia. It argues that by changing some of the rules and neglecting to integrate these changes into the complete institutional setting, policymakers have been unable to achieve their goals. Other constraints on Zambia's agricultural development are of a more technical nature. There are problems with Zambia's infrastructure. This paper argues that these are problems of the provision of public and merit goods mainly occurring in rural areas. Farmers emphasize their limited access to resources like credit, fertilizer, and draft animals. Although these problems could indicate market failures, it is the view of the authors that they are mainly due to transition uncertainties.

description: The field-driven reorientation transition of an anisotropic ferromagnetic monolayer is studied within the context of a finite-temperature Green's function theory. The equilibrium state and the field dependence of the magnon energy gap $E_0$ are calculated for static magnetic field $H$ applied in plane along an easy or a hard axis. In the latter case, the in-plane reorientation of the magnetization is shown to be continuous at T=0, in agreement with free spin wave theory, and discontinuous at finite temperature $T>0$, in contrast with the prediction of mean field theory. The discontinuity in the orientation angle creates a jump in the magnon energy gap, and it is the reason why, for $T>0$, the energy does not go to zero at the reorientation field. Above the Curie temperature $T_C$, the magnon energy gap $E_0(H)$ vanishes for H=0 both in the easy and in the hard case. As $H$ is increased, the gap is found to increase almost linearly with $H$, but with different slopes depending on the field orientation. In particular, the slope is smaller when $H$ is along the hard axis. Such a magnetic anisotropy of the spin-wave energies is shown to persist well above $T_C$ ($T \approx 1.2 T_C$).

description: The Frascati F-Factory DAFNE has been delivering luminosity to the KLOE, DEAR and FINUDA experiments since year 2000. Since April 2004 the KLOE run has been resumed and recently peak luminosity of 1.0x1032 cm-2s-1 and integrated luminosity of 6.2 pb-1/day have been achieved. The scientific program of the three high-energy experiments sharing DAFNE operation will be completed approximately by the end of year 2006. A scientific program for DAFNE beyond that date has not been defined yet and it is matter of discussion in the high-energy physics and accelerator physics communities. In this paper we present some future scenarios for DAFNE, discussing the expected ultimate performances of the machine as it is now and addressing the design for an energy and/or luminosity upgrade. The options presented in the following are not exhaustive and they are intended to give a glance of what is doable using the existing infrastructures.

A polymer-based technique to remove pollutants from soft contact lenses

description: Purpose: To demonstrate an alternative to the rinse and rub (RR) method for cleaning pollutants from the exterior surface of soft contact lenses. This proposed technique is termed Polymer on Polymer Pollutant Removal (PoPPR), which utilizes the elastic properties of polydimethylsiloxane (PDMS) to physically remove contaminants from contact lens surfaces through non-adhesive unpeeling. Methods: Three different ratios of setting agent to polymer PDMS (1:30, 1:40, and 1:50) were evaluated using the PoPPR method against the control method of RR with a commercial multi-purpose lens cleaning solution. Three simulated pollutants of different sizes: pollen (25-40 μm), microbeads (1-5 μm), and nanoparticles (5-10 nm), were used to test the effectiveness of both cleaning methods. The fraction of pollutants removed from each contact lens was recorded and evaluated for significance. Results: PDMS 1:40 was found to be the optimal ratio for lens cleaning using the PoPPR method. For larger particles (>10 μm), no difference was observed between conventional RR and proposed PoPPR method (p > 0.05). However, the new PoPPR technique was significantly better at removing small PM2.5 particles (<2.5 μm) compared to the RR method, specifically for microbeads (p = 0.006) and nanoparticles (p < 0.001). Conclusion: This proof-of-concept work demonstrates that the PoPPR method of cleaning contact lenses is as effective as the conventional cleaning method for larger particles such as pollen. The PoPPR method is more effective at removing extremely fine particulate pollutants, including microplastics and nanoparticles.

description: After protracted and difficult negotiations, agreement was recently reached on the dimensions of a South African-EU free trade deal. Because of South Africa's prominence in the sub-region, implementation of this agreement will have an impact not only on South Africa, but on all the SADC economies. This paper traces how this impact may be felt over time, using a multi-region model constructed to focus on the determination of sectoral and geographic trade patterns. By separately-modeling South Africa and the rest of southern Africa, the model can be used to evaluate how alternative SADC regional trade strategies can influence how the EU deal affects the region's economies; by distinguishing among major trading partners (EU, North America, East Asia), the simulations can help illuminate how the trade deal will likely affect current trade patterns The empirical results lead to a number of conclusions: (1) trade creation dominates trade diversion for the region under all FTA arrangements; (2) the rest of southern Africa benefits from an FTA between the EU and South Africa — the recently signed bilateral agreement is not a “beggar thy neighbor” policy; (3) the rest of southern Africa gains more from zero-tariff access to EU markets than from a partial (50 percent) reduction in global tariffs; and (4) the South African economy is not large enough to serve as a growth pole for the region. Access to EU markets provides substantially bigger gains for the rest of southern Africa than does access to South Africa.

description: This work has performed simulation and experimentation of separating the reaction mixture of the ethyl acetate manufacture by Fischer esterification. Assuming stoichiometric proportion of reactants, mixture with equilibrium composition was subjected to separation. Simulation in the Aspen plus environment using RadFrac module with EQ model was performed. To obtain a range of parameters and variables, sensitivity analysis was performed. Economic analysis was also performed. Experimentation was done to verify the results of simulation using distillation and extractive distillation to obtain the streams with highest purity and unreacted reactants were separated into pure form. A complete flowsheet for separation and purification is suggested.
Ballistic anisotropic magnetoresistance

description: Electronic transport in ferromagnetic ballistic conductors is predicted to exhibit ballistic anisotropic magnetoresistance (BAMR) - a change in the ballistic conductance with the direction of magnetization. This phenomenon originates from the effect of the spin-orbit interaction on the electronic band structure which leads to a change in the number of bands crossing the Fermi energy when the magnetization direction changes. We illustrate the significance of this phenomenon by performing ab-initio calculations of the ballistic conductance in ferromagnetic Ni and Fe nanowires which display a sizable BAMR when the magnetization changes direction from parallel to perpendicular to the wire axis.

description: Differences and similarities in the development paths taken by six East Asian economies (Indonesia, Malaysia, Philippines, Thailand, South Korea, and Taiwan) provide a fertile ground for policy analysis from which important lessons are drawn and major challenges identified for the Indochinese transitional economies (ITEs for short, including Cambodia, Laos, Myanmar, Viet Nam, and China) in advancing the twin objectives of economic growth and poverty reduction. The paper first examines the comparative growth performance of these two groups of Asian economies over the period 1970-1997, describes the significant features of transition and development in the ITEs, and analyzes the relationship between development performance and policies among the East Asian countries. The following major policy challenges for ITEs are discussed towards the end of the paper: (1) sustaining reform efforts toward market orientation; (2) promoting broad-based agricultural growth; (3) supporting labor-intensive, export-oriented industries; (4) dealing with macroeconomic imbalances; and (5) building a strong financial system.

description: We study the discovery potential of down type iso-singlet quarks, $D$, predicted by the $E_6$ GUT model in the ${pp\rightarrow D\bar{D}\rightarrow ZZd\bar{d} \rightarrow \ell^+\ell^-\ell^+\ell^- d\bar{d}}$ channel at the HL-LHC and FCC-hh colliders. The analysis is performed using a high level analysis description language and its runtime interpreter. The study shows that, using solely this channel, HL-LHC can discover $D$ quarks up to a mass of 710 GeV whereas FCC-hh up to 2430 GeV with data collected in their complete run periods.

Block magic : categorization, creation, and influence of Francesca Lia Block’s Enchanted America
Creators: name: McKinlay, Amanda Ellen
Publisher: name: University of British Columbia
Year: 2009

description: This study addresses three questions concerning the young adult literature of Francesca Lia Block: (1) How does Block's writing fit into the tradition of fantasy literature for children? (2) How does she interpret and create her brand of magic realism? (3) What is the relevance of Block's writing to young adults? A review of the limited literary commentary on the subject of Block's works reveals that Block's place and impact in the field of children's literature is largely ignored. Critical literature relates a confusion surrounding Block's categorization in the areas of genre and audience. Block's influence on her young adult readers is scarcely addressed in critical works. Text-based research examines the characteristics of genres relating to Block's literature, including "magic realism," lo real marveilloso americano, "baroque," and "American fairy tale." Content analysis of the stylistic elements at work in Block's literature supports a new classification of Block's works as enchanted American realism. Reviewer comments and the author's personal comments direct Block's literature to a mature audience. The relevance of Block's literature to young adults is established through content and cultural analysis of her fans' online postings. This study reveals that Francesca Lia Block occupies a wholly unique place in children's literature. The findings indicate that Block's works resist classification in standard, pre-conceived categories of genre and audience. Findings also relate the significant influence Block's writing has on young adult readers' psyches.

description: This paper presents a regionally disaggregated computable general equilibrium (CGE) model of Mexico in order to examine the differential effects of external shocks across the regions. The model demonstrates how the internal migration regime is affected by exogenous changes in the presence of threshold effects, in which an exogenous change may not effect regional behavior until the shocks are large enough to overcome the isolation of local markets. The results show that migration helps mitigate the income changes caused by the simulations.

Using high multipolar orders to reconstruct the sound velocity in piezoelectrics from lattice dynamics

description: Information over the phonon band structure is crucial to predicting many thermodynamic properties of materials, such as thermal transport coefficients. Highly accurate phonon dispersion curves can be, in principle, calculated in the framework of density-functional perturbation theory (DFPT). However, well-established techniques can run into trouble (or even catastrophically fail) in the case of piezoelectric materials, where the acoustic branches hardly reproduce the physically correct sound velocity. Here we identify the culprit in the higher-order multipolar interactions between atoms, and demonstrate an effective procedure that fixes the aforementioned issue. Our strategy drastically improves the predictive power of perturbative lattice-dynamical calculations in piezoelectric crystals, and is directly implementable for high-throughput generation of materials databases.

description: We calculate the cross section of J/psi plus jet inclusive production in gamma gamma collisions at next-to-leading order within the factorization formalism of nonrelativistic quantum chromodynamics (NRQCD) focusing on direct photoproduction. Apart from direct J/psi production, we also include the feed-down from directly-produced chi_{cJ} and psi' mesons. We discuss the analytical calculation, in particular the treatment of the various types of singularities and the NRQCD operator renormalization, in some detail. We present theoretical predictions for the future e^+e^- linear collider TESLA, taking into account both brems- and beamstrahlung.

Convergence of elastic flows of curves into manifolds

description: For a given $p\in[2,+\infty)$, we define the $p$-elastic energy $\mathscr{E}$ of a closed curve $γ:\mathbb{S}^1\to M$ immersed in a complete Riemannian manifold $(M,g)$ as the sum of the length of the curve and the $L^p$--norm of its curvature (with respect to the length measure). We are interested in the convergence of the $(L^p,L^{p'})$--gradient flow of these energies to critical points. By means of parabolic estimates, it is usually possible to prove sub-convergence of the flow, that is, convergence to critical points up to reparametrizations and, more importantly, up to isometry of the ambient. Assuming that the flow sub-converges, we are interested in proving the smooth convergence of the flow, that is, the existence of the full limit of the evolving flow. We first give an overview of the general strategy one can apply for proving such a statement. The crucial step is the application of a Lojasiewicz-Simon gradient inequality, of which we present a versatile version. Then we apply such strategy to the flow of $\mathscr{E}$ of curves into manifolds, proving the desired improvement of sub-convergence to full smooth convergence of the flow to critical points. As corollaries, we obtain the smooth convergence of the flow for $p=2$ in the Euclidean space $\mathbb{R}^n$, in the hyperbolic plane $\mathbb{H}^2$, and in the two-dimensional sphere $\mathbb{S}^2$. In particular, the result implies that such flow in $\mathbb{R}^n$ or $\mathbb{H}^2$ remains in a bounded region of the space for any time.
