description: It is demonstrated both theoretically and experimentally that the spin chirality associated with a noncoplanar spin configuration produces a magneto-optical effect. Numerical study of the two-band Hubbard model on a triangle cluster shows that the optical Hall conductivity $σ_{xy}(ω)$ is proportional to the spin chirality. The detailed comparative experiments on pyrochlore-type molybdates $R_2$Mo$_2$O$_7$ with $R=$Nd (Ising-like moments) and $R=$Gd (Heisenberg-like ones) clearly distinguishes the two mechanisms, i.e., spin chirality and spin-orbit interactions. It is concluded that for $R$=Nd, $σ_{xy}(ω)$ is dominated by the spin chirality for the dc ($ω=0$) and the $d \to d$ incoherent intraband optical transitions between Mo atoms.

description: We focused on the Socio-Economic Evaluation of Farmer Field School Training on Integrated Pest Management in the humid forest region of Cameroon. The main objective was to assess the impact of training on integrated pest management (IPM) on cocoa farmer field school graduates. The results indicate that shade management, phytosanitary harvest, pruning, improved spraying practices and grafting of improved materials were adopted at the rate of 94, 93, 90, 66 and 35 % respectively, with the overall rate of adoption being 76 %. There was a 47 % reduction in the frequency of spraying fungicides and a 17 % reduction in the number of sprayers applied per treatment following the implementation of the training. Labour inputs increased significantly for pruning, phytosanitary harvest, and shade management but decreased for spraying. A partial budget analysis reveals that the IPM practices lowered overall costs of production by 11 % relative to previous practices. The poster presenting the synthesis of this work comprises a general introduction, a methodology and study area map, results and discussion which comprise two photographs of farmer field school activities, a graph and a table of different technical results, a short conclusion and recommendation.
"The person you call ’I’" : configurations of identity in the poetry of P. K. Page
Creators: name: Stiles, Diane
Publisher: name: University of British Columbia
Year: 2009

description: Many of P.K. Page's poems configure identity in terms of encounters between the self and an "other" sometimes internal and sometimes external to the self. Ego-psychology and relational psychoanalysis suggest some fundamental principles describing the dynamics of these encounters. Although the self in Page's poetry apparently evolves from objectifying the other to identifying with it, this overt tendency towards identification is counterbalanced by less obvious tendencies towards objectification of the other. Some of her earliest speakers objectify and criticize the "feminine" behaviour of office workers. Her representations of female subjects become increasingly sympathetic, until in "After Rain" (1956), the speaker tries to integrate a sense of femininity into her own identity. She achieves this, however, by aligning masculinity with a lower socio-economic class than her own. Speakers in other early poems progress from objectifying to identifying with conflicts represented along Freudian lines. In the early 1940s, third-person speakers describe conflicts between other people. In later poems these conflicts are progressively internalized, until in "Melanie's Nite-Book" (1976) the speaker acknowledges the connections between her internal psychic conflicts and her relationship with her father. At the same time, however, this speaker objectifies her mother. In Page's mid-career poetry, her speakers progressively acknowledge other psychological conflicts, configured in Jungian terms. Whereas her early speakers recoil in horror from the subconscious elements of their subjects' minds, the later "Preparation" (1971) negotiates an uneasy truce between the conscious and unconscious elements of the speaker's own mind. Page's later "transcendent" poetry is influenced by Sufism. Her speakers' progressive acceptance of the internal other, however, depends on the absence of a true external other who could challenge these later visions of unity. A few of Page's early poems suggest that paradoxically, we arrive at our fullest experience of the self through encountering an other we cannot control through either objectification or identification. Page's oeuvre offers a fragmented but remarkably comprehensive impression of a self as it evolves through adult life. At the same time, examining her various configurations of identity reveals dimensions of the poetry that no other critical approach has illuminated.

description: This study analyses the impact of the liberalization on the intensification of maize production in Kenya. It first analyses the impact of liberalization on input and output prices, followed by an analysis of farmer practices comparing two major farmer surveys, from 1992 and 2002. The results show that liberalization has had a general positive impact on the evolution of prices, with a decrease of input/output price ratios. However, fluctuations of maize prices has become very high and, combined with a decrease of marketing by the marketing board, has increased the uncertainty in maize production. The liberalization has also resulted in a decrease in extension services. Fortunately, farmers have an increased access to credit services. The combined effect of prices and access to services has resulted in little change in the number of farmers using new maize technologies, in particular improved varieties and fertilizer. The dose of fertilizer per ha has, however, decreased. As a result, yields have not increased. The analysis also showed that credit and extension have a major effect on adoption and, indirectly, on yield. The results indicate that an effort is needed to improve extension access. While the improved access to credit is encouraging, more than half the farmers still miss this essential service. Finally, the increased price fluctuation and market uncertainty should be addressed through improved use of price buffer mechanisms. Market access can also substantially be improved through investment in infrastructure.

description: This paper presents an analysis of agricultural contracts using a transaction costs approach. We contend that in a context of modern agriculture, with well defined property rights, agricultural contracts must balance costs and benefits, aligning tenant and landlord incentives towards a similar objective. The study debates the potential effects of tenancy status and duration of contracts, over soil conservation and input use. We present empirical evidence about the effects over the soil and input use in tenant (fixed rent or sharecropping) and owner-operator farms using farm level data from the 2002 National Agricultural Census of Argentina. The empirical results show some differential effects but do not support a general and clear negative effect for tenancy arrangements. Our intuition is that the interaction among specific characteristics of farmers (education, experience, assets, etc.), the natural resources endowment (soil fertility) and the economic and institutional environment (labor markets, monitoring costs, property rights, rule of law etc.) are more important factors than the land tenancy or contract type itself.

description: The recent discovery of two-dimensional (2D) magnets offers unique opportunities for the experimental exploration of low-dimensional magnetism4 and the magnetic proximity effects, and for the development of novel magnetoelectric, magnetooptic and spintronic devices. These advancements call for 2D materials with diverse magnetic structures as well as effective probes for their magnetic symmetries, which is key to understanding intralayer magnetic order and interlayer magnetic coupling. Here we apply second harmonic generation (SHG), a technique acutely sensitive to symmetry breaking, to probe the magnetic structure of a new 2D magnetic semiconductor, CrSBr. We find that CrSBr monolayers are ferromagnetically ordered below 146 K, an observation enabled by the discovery of a giant magnetic dipole SHG effect in the centrosymmetric 2D structure. In multilayers, the ferromagnetic monolayers are coupled antiferromagnetically, with the Néel temperature notably increasing with decreasing layer number. The magnetic structure of CrSBr, comprising spins co-aligned in-plane with rectangular unit cell, differs markedly from the prototypical 2D hexagonal magnets CrI3 and Cr2Ge2Te6 with out-of-plane moments. Moreover, our SHG analysis suggests that the order parameters of the ferromagnetic monolayer and the antiferromagnetic bilayer are the magnetic dipole and the magnetic toroidal moments, respectively. These findings establish CrSBr as an exciting 2D magnetic semiconductor and SHG as a powerful tool to probe 2D magnetic symmetry, opening the door to the exploration of coupling between magnetic order and excitonic/electronic properties, as well as the magnetic toroidal moment, in a broad range of applications.

description: Recently Barrett and Kok (BK) proposed an elegant method for entangling separated matter qubits. They outlined a strategy for using their entangling operation (EO) to build graph states, the resource for one-way quantum computing. However by viewing their EO as a graph fusion event, one perceives that each successful event introduces an ideal redundant graph edge, which growth strategies should exploit. For example, if each EO succeeds with probability p=0.4 then a highly connected graph can be formed with an overhead of only about ten EO attempts per graph edge. The BK scheme then becomes competitive with the more elaborate entanglement procedures designed to permit p to approach unity.

description: Since 1996, different formats of whole-farm insurance (WFI) have been launched in North America and Spain. Their rationale is to pool all farm's insurable risks into a single policy that provides cheaper coverage against the farm's revenue losses. We evaluate the gains of moving from a situation of full insurance coverage delivered by crop-specific policies to WFI. Based on the records of individual farmers gathered by the Spanish Agricultural Insurance Agency (ENESA), we select two representative farms in Valencia that have consistently purchased insurance during 1993-2004 for three crops (apricots, plums and wine grapes). WFI is designed to deliver exactly the same expected revenue than does the combined effects of three crop-specific multiple-peril insurance policies, covering from the same risks. We carry out Monte-Carlo simulations to compare crop-specific insurance with WFI, looking at premium differences, farms' revenues, and farmers' utilities (DARACRRA). From ENESA's database we evaluate the parameters of the yield distribution functions, the eligible losses distribution functions and their correlation. Results show that WFI is slightly superior to crop-specific insurance. Premia are 20% cheaper, and certainty equivalents slightly larger. Yet, the left tail of the revenue distribution is only weakly reduced by either insurance strategy, due to crop risks that are not covered by either policy. The main conclusion is that, if crop-specific insurance is sufficiently mature, farmers would benefit from WFI and Governments would enhance the efficiency of their insurance subsidies.

description: Hypertension is a medical condition that is well-established as a risk factor for many major diseases. For example, it can cause alterations in the cardiac structure and function over time that can lead to heart related morbidity and mortality. However, at the subclinical stage, these changes are subtle and cannot be easily captured using conventional cardiovascular indices calculated from clinical cardiac imaging. In this paper, we describe a radiomics approach for identifying intermediate imaging phenotypes associated with hypertension. The method combines feature selection and machine learning techniques to identify the most subtle as well as complex structural and tissue changes in hypertensive subgroups as compared to healthy individuals. Validation based on a sample of asymptomatic hearts that include both hypertensive and non-hypertensive cases demonstrate that the proposed radiomics model is capable of detecting intensity and textural changes well beyond the capabilities of conventional imaging phenotypes, indicating its potential for improved understanding of the longitudinal effects of hypertension on cardiovascular health and disease.

description: We examine in theory and by numerical simulation, the dynamic process of switching from a zero voltage to a finite voltage state in a Josephson junction circuit. The theoretical model describes small capacitance Josephson junctions which are overdamped at high frequencies, and can be applied to detection of the quantum state of a qubit circuit. We show that the speed and fidelity of the readout are strongly influenced by the topology of the phase space attractors. The readout will be close to optimal when choosing the circuit parameters so as to avoid having an unstable limiting cycle which separates the two basins of attraction.

description: Crop genetic resources are the building block of sustainable agricultural development as these can be used to develop crop varieties adaptable to heterogeneous environmental conditions. Nepal is considered the center of origin and diversity for Asian rice, which still has many landraces. However, there has been continuous loss of genetic diversity and concern over it has grown in recent years. The main objective of this paper is to identify the determinants of variety diversity on-farm in the rainfed ecosystem of Nepal by using two-limit Tobit procedure. The diversity on farm appeared to be quite high evaluated based on the number of named varieties grown by the farmers. Majority of the farmers cultivated both modern varieties and landraces simultaneously and the rice production is also getting commercialized gradually. The results showed that the motivating factors for variety diversification are the heterogeneous production environments, risk consideration and farmers' participation in the markets. However, the farmers' dependency on formal extension system for the seed of limited varieties led to reduction in diversity. Diverse crop genetic resources on-farm can generate both commercial and noncommercial benefits. As economies develop, markets play an important role in shaping farmers' choices and use of cultivars diversity. Therefore, the public investments are needed in developing the infrastructures to support the formation of niche markets and increasing the farmers' participation in crop breeding and improvement programs. Also, the formal extension system should be mobilized for the production and distribution of seeds of many varieties including the landraces.

description: A wave front of Fisher and Kolmogorov, Petrovskii, and Piskunov type involving two species A and B with different diffusion coefficients $D_A$ and $D_B$ is studied using a master equation approach in dilute and concentrated solutions. Species A and B are supposed to be engaged in the autocatalytic reaction A+B -> 2A. Contrary to the results of a deterministic description, the front speed deduced from the master equation in the dilute case sensitively depends on the diffusion coefficient of species B. A linear analysis of the deterministic equations with a cutoff in the reactive term cannot explain the decrease of the front speed observed for $D_B > D_A$. In the case of a concentrated solution, the transition rates associated with cross-diffusion are derived from the corresponding diffusion fluxes. The properties of the wave front obtained in the dilute case remain valid but are mitigated by cross-diffusion which reduces the impact of different diffusion coefficients.

description: Complex categorical data is often hierarchically coupled with heterogeneous relationships between attributes and attribute values and the couplings between objects. Such value-to-object couplings are heterogeneous with complementary and inconsistent interactions and distributions. Limited research exists on unlabeled categorical data representations, ignores the heterogeneous and hierarchical couplings, underestimates data characteristics and complexities, and overuses redundant information, etc. The deep representation learning of unlabeled categorical data is challenging, overseeing such value-to-object couplings, complementarity and inconsistency, and requiring large data, disentanglement, and high computational power. This work introduces a shallow but powerful UNsupervised heTerogeneous couplIng lEarning (UNTIE) approach for representing coupled categorical data by untying the interactions between couplings and revealing heterogeneous distributions embedded in each type of couplings. UNTIE is efficiently optimized w.r.t. a kernel k-means objective function for unsupervised representation learning of heterogeneous and hierarchical value-to-object couplings. Theoretical analysis shows that UNTIE can represent categorical data with maximal separability while effectively represent heterogeneous couplings and disclose their roles in categorical data. The UNTIE-learned representations make significant performance improvement against the state-of-the-art categorical representations and deep representation models on 25 categorical data sets with diversified characteristics.

description: We study vacuum alignment in theories in which the chiral symmetry of a set of massless fermions is both spontaneously and explicitly broken. We find that transitions occur between different phases of the fermions' CP symmetry as parameters in their symmetry breaking Hamiltonian are varied. We identify a new phase that we call pseudoCP-conserving. We observe first and second-order transitions between the various phases. At a second-order (and possibly first-order) transition a pseudoGoldstone boson becomes massless as a consequence of a spontaneous change in the discrete, but not the continuous, symmetry of the ground state. We relate the masslessness of these ``accidental Goldstone bosons'' (AGBs) bosons to singularities of the order parameter for the phase transition. The relative frequency of CP-phase transitions makes it commonplace for the AGBs to be light, much lighter than their underlying strong interaction scale. We investigate the AGBs' potential for serving as light composite Higgs bosons by studying their vacuum expectation values, finding promising results: AGB vevs are also often much less than their strong scale.

description: Taking advantage of more than 11 years of Fermi-LAT data, we perform a new and deep analysis of the pulsar wind nebula (PWN) HESS J1825-137. Combining this analysis with recent H.E.S.S. results we investigate and constrain the particle transport mechanisms at work inside the source as well as the system evolution. The PWN is studied using 11.6 years of Fermi-LAT data between 1 GeV and 1 TeV. In particular, we present the results of the spectral analysis and the first energy-resolved morphological study of the PWN HESS J1825-137 at GeV energies, which provide new insights into the gamma-ray characteristics of the nebula. An optimised analysis of the source returns an extended emission region larger than 2$^{\circ}$, corresponding to an intrinsic size of about 150 pc, making HESS J1825-137 the most extended gamma-ray PWN currently known. The nebula presents a strong energy dependent morphology within the GeV range, moving from a radius of $\sim1.4^\circ$ below 10 GeV to a radius of $\sim$0.8$^\circ$ above 100 GeV, with a shift in the centroid location. Thanks to the large extension and peculiar energy-dependent morphology, it is possible to constrain the particle transport mechanisms inside the PWN HESS J1825-137. Using the variation of the source extension and position, as well as the constraints on the particle transport mechanisms, we present a scheme for the possible evolution of the system. Finally, we provide an estimate of the electron energy density and we discuss its nature in the PWN and TeV halo-like scenario.

description: Detailed weekly sales transactions data for the period January 2000-June 2001 from three frontier markets in the central corridor of West Africa were analyzed to identify the factors influencing short-run, intra-year cattle prices. The empirical results indicate that in addition to market location and seasonality of supply and sales, market participants show systemic preferences for specific cattle attributes (sex, weight, condition and finish) and are willing to pay premium prices consistent with their preferences. Communicating this information to producers can assist them to tailor their production and marketing decisions to meet market expectations and thereby improve their competitiveness, profitability and intra-regional livestock trade. Innovative policy and institutional approaches to improve market information dissemination and ease other constraints that tend to dampen supply response, even in the face of favorable prices, are discussed in the paper.

description: The automation strategy of today’s smart cities relies on large IoT (internet of Things) systems that collect big data analytics to gain insights. Although there have been recent reviews in this field, there is a remarkable gap that addresses four sides of the problem. Namely, the application of video surveillance in smart cities, algorithms, datasets, and embedded systems. In this paper, we discuss the latest datasets used, the algorithms used, and the recent advances in embedded systems to form edge vision computing are introduced. Moreover, future trends and challenges are addressed.

description: In the context of extrasolar planet direct detection, we evaluated the performance of differential imaging with ground-based telescopes. This study was carried out in the framework of the VLT-Planet Finder project and is further extended to the case of Extremely Large Telescopes. Our analysis is providing critical specifications for future instruments mostly in terms of phase aberrations but also regarding alignments of the instrument optics or offset pointing on the coronagraph. It is found that Planet Finder projects on 8m class telescopes can be successful at detecting Extrasolar Giant Planets providing phase aberrations, alignments and pointing are accurately controlled. The situation is more pessimistic for the detection of terrestrial planets with Extremely Large Telescopes for which phase aberrations must be lowered at a very challenging level.

description: Trade-related factors influencing the decline in domestic market share of U.S. red meats were investigated. The study are to examine the effects of relative meat price changes (domestic and imported), the relative U.S. dollar values and their volatilities, and the effect that BSE has had on U.S. red-meat trade. The results show that the relative meat price and exchange rate indices as well as their volatilities significantly affect the U.S. market share of its total meat utilization. The BSE dummy variable has an expected positive sign, though it was statistically insignificant.

description: Stars that pass too close to a super-massive black hole may be disrupted by strong tidal forces. OGLE16aaa is one such tidal disruption event (TDE) which rapidly brightened and peaked in the optical/UV bands in early 2016 and subsequently decayed over the rest of the year. OGLE16aaa was detected in an XMM-Newton X-ray observation on June 9, 2016 with a flux slightly below the Swift/XRT upper limits obtained during the optical light curve peak. Between June 16-21, 2016, Swift/XRT also detected OGLE16aaa and based on the stacked spectrum, we could infer that the X-ray luminosity had jumped up by more than a factor of ten in just one week. No brightening signal was seen in the simultaneous optical/UV data to cause the X-ray luminosity to exceed the optical/UV one. A further XMM-Newton observation on November 30, 2016 showed that almost a year after the optical/UV peak, the X-ray emission was still at an elevated level, while the optical/UV flux decay had already leveled off to values comparable to those of the host galaxy. In all X-ray observations, the spectra were nicely modeled with a 50-70 eV thermal component with no intrinsic absorption, with a weak X-ray tail seen only in the November 30 XMM-Newton observation. The late-time X-ray behavior of OGLE16aaa strongly resembles the tidal disruption events ASASSN-15oi and AT2019azh. We were able to pinpoint the time delay between the initial optical TDE onset and the X-ray brightening to $182 \pm 5$ days, which may possibly represent the timescale between the initial circularization of the disrupted star around the super-massive black hole and the subsequent delayed accretion. Alternatively, the delayed X-ray brightening could be related to a rapid clearing of a thick envelope that covers the central X-ray engine during the first six months.

description: This study discriminates FDI technology spillover from learning effects. Whenever learning takes time, our model predicts that foreign investors deduct the economic value of learning from wages of inexperienced workers and add it to experienced ones to prevent them from moving to local competitors. Hence, the national wage bill is unaffected by foreign takeovers. In contrast to learning, technology spillover effects occur whenever a worker with MNE experience contributes more to local firms' than to MNEs' productivity. In this case, experienced MNE workers are hired by local firms and the host country obtains a welfare gain. We investigate empirically wages, productivity, and worker turnover during the course of foreign takeovers on employee-employer matched data of Hungary and find evidence consistent with learning, but not with FDI technology spillovers.
Spitzer Detection of PAH and Silicate Dust Features in the Mid-Infrared Spectra of z~2 Ultraluminous Infrared Galaxies

description: We report the initial results from a Spitzer GO-1 program to obtain low resolution, mid-infrared spectra of infrared luminous galaxies at z~1-2. This paper presents the spectra of eight sources observed with the Spitzer InfraRed Spectrograph (IRS). Of the eight spectra, six have mid-IR spectral features, either emission from Polycyclic Aromatic Hydrocarbon (PAH) or silicate absorption. Based on these mid-IR features, the inferred six redshifts are in the range of 1.8-2.6. The remaining two spectra detect only strong continua, thus do not yield redshift information. Strong, multiple PAH emission features are detected in two sources, and weak PAH emission in another two. These data provide direct evidence that PAH molecules are present and directly observable in ULIRGs at z~2. The six sources with measured redshifts are dusty, infrared luminous galaxies at z~2 with estimated $L_{bol} \sim 10^{13}L_\odot$. Of the eight sources, two appear starburst dominated; two with only power law continua are probably type I QSOs; and the remaining four are likely composite systems containing a buried AGN and a starburst component. Since half of our sample are optically faint sources with R>25.5mag (Vega), our results demonstrate the potential of using mid-infrared spectroscopy, especially the Aromatic and silicate features produced by dust grains to directly probe optically faint and infrared luminous populations at high redshift.

Note on DBI dynamics of Dbrane Near NS5-branes

description: In this note, we investigate the homogeneous radial dynamics of (Dp, NS5)-systems without and with one compactified transverse direction, in the framework of DBI effective action. During the homogeneous evolution, the electric field on the D-brane is always conserved and the radial motion could be reduced to an one-dimension dynamical system with an effective potential. When the Dp-brane energy is not high, the brane moves in a restricted region, with the orbits depending on the conserved energy, angular momentum through the form of the effective potential. When the Dp-brane energy is high enough, it can escape to the infinity. It turns out that the conserved angular momentum plays an interesting role in the dynamics. Moreover, we discuss the gauge dynamics around the tachyon vacuum and find that the dynamics is very reminiscent of the string fluid in the rolling tachyon case.
