description: A new class of pulsating binary stars was recently discovered, whose pulsation amplitudes are strongly modulated with orbital phase. Stars in close binaries are tidally distorted, so we examine how a star's tidally induced asphericity affects its oscillation mode frequencies and eigenfunctions. We explain the pulsation amplitude modulation via tidal mode coupling such that the pulsations are effectively confined to certain regions of the star, e.g., the tidal pole or the tidal equator. In addition to a rigorous mathematical formalism to compute this coupling, we provide a more intuitive semi-analytic description of the process. We discuss three resulting effects: 1. Tidal alignment, i.e., the alignment of oscillation modes about the tidal axis rather than the rotation axis; 2. Tidal trapping, e.g., the confinement of oscillations near the tidal poles or the tidal equator; 3. Tidal amplification, i.e., increased flux perturbations near the tidal poles where acoustic modes can propagate closer to the surface of the star. Together, these phenomena can account for the pulsation amplitude and phase modulation of the recently discovered class of "tidally tilted pulsators." We compare our theory to the three tidally tilted pulsators HD 74423, CO Cam, and TIC 63328020, finding that tidally trapped modes that are axisymmetric about the tidal axis can largely explain the first two, while a non-axisymmetric tidally aligned mode is present in the latter. Finally, we discuss implications and limitations of the theory, and we make predictions for the many new tidally tilted pulsators likely to be discovered in the near future.

description: Several physical quantities of light hadrons are examined by a new holographic model of QCD, which is the modified version of the one proposed by Erlich et al. defined on AdS${}_5$. In our model, AdS${}_5$ is deformed by a non-trivial bulk scalar, this is corresponding to adding the mass term of the adjoint fermions to the 4d SYM theory dual to the gravity on AdS${}_5$. We find that this deformation should be taken to be rather small, but its important effects are also seen.

description: Advanced LIGO and Virgo have detected ten binary black hole mergers by the end of their second observing run. These mergers have already allowed constraints to be placed on the population distribution of black holes in the Universe, which will only improve with more detections and increasing sensitivity of the detectors. In this paper we develop techniques to measure the angular distribution of black hole mergers by measuring their statistical N-point correlations through hierarchical Bayesian inference. We apply it to the special case of two-point angular correlations using a Legendre polynomial basis on the sky. Building on the mixture model formalism introduced in Ref.[1] we show how one can measure two-point correlations with no threshold on significance, allowing us to target the ensemble of sub-threshold binary black hole mergers not resolvable with the current generation of ground based detectors. We also show how one can use these methods to correlate gravitational waves with other probes of large scale angular structure like galaxy counts, and validate both techniques through simulations.

description: Managing the risk associated with farming is challenging. Fortunately, farmers have a variety of risk management tools at their disposal. This series of case studies examines how crop insurance can be used to manage some of the risks faced by farmers. The examples illustrate how crop insurance purchases would impact the returns generated to a farming enterprise. While the examples cover a variety of commodities and insurance products, they do not consider every possible risk that might arise. Likewise, they do not consider all of the possible financial situations that might be experienced by a farmer. Instead, they focus on highlighting how crop insurance impacts the profitability of the farm. Companion spreadsheets are available for all of the examples so that readers can examine a wider range of scenarios than those discussed in the examples.

description: An investigation of the relative costs and benefits of marketing channels used by typical smallscale diversified vegetable crop producers is conducted. Using case study evidence from four small farms in Central New York, this study compares the performance of wholesale and direct marketing channels, including how the factors of risk, owner and paid labor, price, lifestyle preferences, and sales volume interact to impact optimal market channel selection. Given the highly perishable nature of the crops grown, along with the risks and potential sales volume of particular channels, a combination of different marketing channels is needed to maximize overall firm performance. Accordingly, a ranking system is developed to summarize the major firm-specific factors across channels and to prioritize those channels with the greatest opportunity for success based on individual firm preferences.

These boundary conditions represent the coupling of the system with two heat reservoirs at different temperatures. Our analysis is not perturbative around the equilibrium. We employ a fixed point argument to reduce the study of the model with non-linear collisional interactions to the linear BGK.

description: We describe here the Atomic bremsstrahlung - emission of continuous spectrum electromagnetic radiation, which is generated in collisions of particles that have internal deformable structure that includes positively and negatively charged constituents. The deformation of one of or both colliding partners induces multiple, mainly dipole, time-dependent electrical moments that become a source of radiation. The history of Atomic bremsstrahlung invention is presented and it's unusual in comparison to ordinary bremsstrahlung properties are discussed. As examples, fast electron - atom, non-relativistic and relativistic collisions are considered. Attention is given to ion - atom and atom - atom collisions. Specifics of elastic and inelastic (i.e. radiation accompanied by destruction of collision partners) Atomic bremsstrahlung will be mentioned. Attention will be given to possible manifestation of Atomic bremsstrahlung in Nature and in some exotic systems, for instance scattering of electrons upon muonic hydrogen. Some cooperative effects connected to Atomic bremsstrahlung will be considered. New classical schemes similar to Atomic bremsstrahlung will be presented.

description: PURPOSE: To update the Carleton Laboratory for Radiotherapy Physics (CLRP) TG-43 dosimetry database for low-energy (< 50 keV) photon-emitting low-dose rate (LDR) brachytherapy sources utilizing the open-source EGSnrc application egs_brachy rather than the BrachyDose application used previously for 27 LDR sources in the 2008 CLRP version (CLRPv1). CLRPv2 covers 40 sources (Pd-103, I-125, Cs-131). A comprehensive set of TG-43 parameters is calculated, including dose-rate constants, radial dose functions with functional fitting parameters, 1D and 2D anisotropy functions, along-away dose-rate tables, Primary-Scatter separation dose tables (for some sources), and mean photon energies. The database also documents the source models which will become part of the egs_brachy distribution. METHODS: Datasets are calculated after a systematic recoding of the source geometries using the egs++ geometry package and its egs_brachy extensions. Full scatter water phantoms with varying voxel resolutions in cylindrical coordinates are used for dose calculations. New statistical uncertainties of source volume corrections for phantom voxels which overlap with brachytherapy sources are implemented in egs_brachy, and all CLRPv2 data include these uncertainties. For validation, data are compared to CLRPv1 and other data in the literature. DATA ACCESS/FORMAT: Data are available at https://physics.carleton.ca/ clrp/egs_brachy/seed_database_v2. As well as being presented graphically in comparisons to previous calculations, data are available in Excel (.xlsx) spreadsheets for each source. APPLICATIONS: The database has applications in research, dosimetry, and brachytherapy planning. This comprehensive update provides the medical physics community with more accurate TG-43 dose evaluation parameters, as well as fully-benchmarked source models distributed with egs_brachy.

description: The Uniform Small Loan Law (USLL) was the Russell Sage Foundation’s primary device for fighting what it viewed as the scourge of high-rate lending to poor people in the first half of the twentieth century. The USLL created a new class of lenders who could make small loans at interest rates exceeding those allowed for banks under the normal usury laws. About two-thirds of the states had passed the USLL by the 1930. This paper describes the USLL and then uses econometric models to investigate the state characteristics that influenced the law’s passage. We find that urbanization and state-level economic characteristics played significant roles. So did measures of the state’s banking system. We find no evidence that party-political affiliations had any effect, which is consistent with the USLL’s “progressive” character. Finally, we find little evidence that the passage of the USLL in one state made passage more likely in neighboring or similar states. If anything, the cross-state influences were negative. Our findings suggest that the Russell Sage Foundation only imperfectly understood the political economy of the USLL, and that a different overall approach might have produced a result closer to their aims.

Our results indicate that the $1^{-+}$ exotic exhibits significant curvature close to the chiral limit, and yield a $1^{-+}$ mass in agreement with the $π_1 (1600)$ candidate and exclusive of the $π_1 (1400)$.

Journeys in Search of Travel Writing: A critical-creative interrogation of contemporary travel writing as a genre
Creators: name: Hannigan, Timothy A.
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: This thesis interrogates ethical issues in contemporary travel writing, drawing its critical underpinning from the body of postcolonial scholarship on the genre which has emerged since the publication of Edward Said’s Orientalism (1978). The thesis focuses on representations of alterity and the travellee, and the issue of fictionalisation in notionally nonfictional texts. It is delivered as a first-person narrative, using the literary form of travel writing itself to discuss its findings. Scholarly research and creative practice are bound together in a single critical-creative text.The central research presented here consists of a series of qualitative interviews with prominent travel writers and others associated with the genre: Philip Marsden, Nicholas Jubber, Colin Thubron, Nick Danziger, Robin Hanbury-Tenison, Patrick Barkham, Dervla Murphy, Rory MacLean, Sara Wheeler, Samanth Subramanian, William Dalrymple, Monisha Rajesh and Kapka Kassabova; the publisher Barnaby Rogerson, the scholar Carl Thompson and a group of readers of travel writing. There are also examinations of the archives of two canonical figures of twentieth-century British travel writing – Wilfred Thesiger and Patrick Leigh Fermor – with a focus on the layered production and resultant elements of fictionalisation in their major works; and a survey of nineteenth-century travel writing about Cornwall with a focus on questions of travellee reception.The first-person narrative form of the thesis, meanwhile, allows for a self-reflexive approach, and an immediate testing of the generic limitations of travel writing in direct response to the issues raised in the interviews and archival studies. The aim here is to investigate travel writing’s capacity for internal critique, and at the same time to foreground the subjective and transformative nature of scholarly research.

Shapes and Alignments of Galaxy Cluster Halos

Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: We present distribution functions and spatial correlations of the shapes of dark matter halos derived from Hubble Volume simulations of a LambdaCDM universe. We measure both position and velocity shapes within spheres encompassing mean density 200 times the critical value, and calibrate small-N systematic errors using Poisson realizations of isothermal spheres and higher resolution simulations. For halos more massive than 3x10^{14} Msun/h, the shape distribution function peaks at (minor/major, intermediate/major) axial ratios of (0.64,0.76) in position, and is rounder in velocity, peaking at (0.72,0.82). Halo shapes are rounder at lower mass and/or redshift; the mean minor axis ratio in position follows (M,z) = c_{15,0} [1-α\ln(M/10^{15}Msun/h)] (1+z)^{-ε}, with c_{15,0}=0.631 \pm 0.001, α=0.023 \pm 0.002 and ε=0.086 \pm 0.004. Position and velocity principal axes are well aligned in direction, with median alignment angle $22^\circ$, and the axial ratios in these spaces are correlated in magnitude. We investigate mark correlations of halo pair orientations using two measures: a simple scalar product shows $\ge 1%$ alignment extending to $30 \hinv \mpc$ while a filamentary statistic exhibits non-random alignment extending to scales $\sims 200 \hinv \mpc$, ten times the sample two-point correlation length and well into the regime of negative two-point correlation. Cluster shapes are unaffected by the large-scale environment; the shape distribution of supercluster members is consistent with that of the general population.

description: The anomalous proximity effect in dirty superconducting junctions is one of most striking phenomena highlighting the profound nature of Majorana bound states and odd-frequency Cooper pairs in topological superconductors. Motivated by the recent experimental realization of planar topological Josephson junctions, we describe the anomalous proximity effect in a superconductor/semiconductor hybrid, where an additional dirty normal-metal segment is extended from a topological Josephson junction. The topological phase transition in the topological Josephson junction is accompanied by a drastic change in the low-energy transport properties of the attached dirty normal-metal. The quantization of the zero-bias differential conductance, which appears only in the topologically nontrivial phase, is caused by the penetration of the Majorana bound states and odd-frequency Cooper pairs into a dirty normal-metal segment. As a consequence, we propose a practical experiment for observing the anomalous proximity effect.

description: In this research, we improve upon the current state of the art in entity retrieval by re-ranking the result list using graph embeddings. The paper shows that graph embeddings are useful for entity-oriented search tasks. We demonstrate empirically that encoding information from the knowledge graph into (graph) embeddings contributes to a higher increase in effectiveness of entity retrieval results than using plain word embeddings. We analyze the impact of the accuracy of the entity linker on the overall retrieval effectiveness. Our analysis further deploys the cluster hypothesis to explain the observed advantages of graph embeddings over the more widely used word embeddings, for user tasks involving ranking entities.
Dynamic Social Networks Across The Landscape. A Petrological Study Of Bronze Age Ceramics In Nuragic Sardinia (Italy)
Creators: name: Gradoli, Maria G.
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: The thesis focused on the relationship between ceramic technology and social organisation and studied 488 ceramic thin sections from eight Bronze Age settlements located in two micro-regions of south-central Sardinia.The approach proposed - analysing ceramic fabric variability among selected common nuragic vessel forms in close connection with the domestic architectures - represents an innovation with respect to the previous studies of pottery in Sardinia, that have mainly focused on stylistic attributes and their use in assessing a chronological typology.The principal research question of this thesis was whether a technological study of a selected group of pottery coming from nuragic domestic structures, could shed new light on the pattern of pottery production, consumption and exchange at an inter-site level among the archaeological settlements considered. The petrographic analysis and laboratory tests contributed successfully to the establishment of the relevant fabric groups and classes of raw materials used by potters, their characterization, the reconstruction of certain technological and social choices, and identification of the provenance of the principal clays used. All this constitutes a firm basis for future analysis of ceramics from the two study areas and for the whole of Sardinia.One of the most striking results achieved was the realization that nuragic plain domestic pottery, like the imported exotica coming from the Aegean, could have been circulating among nuragic settlements as exchanged items, at an inter-site and inter-regional level throughout the Bronze Age. This result was complemented by the identification, in the landscape between the Orroli plateau and the Mulargia river valleys, of several distinct pottery traditions that might reflect patterns of interaction between groups of people of different cultural affiliations.

We find an unconventional superconducting ground state for intermediate charge carrier interaction, sandwiched between a conventional metal at weak coupling and a spin liquid at larger coupling. Most remarkably, the excitation spectrum is dramatically renormalized and is found to be the driving force for the formation of the unusual superconducting state.

description: Monte Carlo event generators are an essential tool for data analysis in collider physics. To include subleading quantum corrections, these generators often need to produce negative weight events, which leads to statistical dilution of the datasets and downstream computational costs for detector simulation. Building on the recent proposal of a positive resampler method to rebalance weights within histogram bins, we introduce neural resampling: an unbinned approach to Monte Carlo reweighting based on neural networks that scales well to high-dimensional and variable-dimensional phase space. We pay particular attention to preserving the statistical properties of the event sample, such that neural resampling not only maintains the mean value of any observable but also its Monte Carlo uncertainty. This uncertainty preservation scheme is general and can also be applied to binned (non-neural network) resampling. To illustrate our neural resampling approach, we present a case study from the Large Hadron Collider of top quark pair production at next-to-leading order matched to a parton shower.

description: Why did Victorian Britain invest so much capital abroad? We collect over 500,000 monthly returns of British and foreign securities trading in London and the United States between 1866 and 1907. These heretofore-unknown data allow us to better quantify the historical benefits of international diversification and revisit the question of whether British Victorian investor bias starved new domestic industries of capital. We find no evidence of bias. A British investor who increased his investment in new British industry at the expense of foreign diversification would have been worse off. The addition of foreign assets significantly expanded the mean-variance frontier and resulted in utility gains equivalent to a meaningful increase in lifetime consumption.
GAMIFICATION IN LANGUAGE LEARNING

description: One of the most powerful means in education, gamification has been introduced for language learning. This paper explores the pros of gamification in learning foreign languages relating to motivation, enhancement of language competence and speech skills and student engagement. Based on existing literature, we identify that gamification enables customised learning experiences and increases learner motivation as well as language mastery in vocabularies, grammar practices and overall communication skills. Besides, gamification creates a positive learning atmosphere which is good for student retention and engagement. This shows the gamification not only acts as a motivator, but also as an efficient pedagogical practice for language learners in different educational backgrounds.

description: Group liability in microcredit purports to improve repayment rates through peer screening, monitoring, and enforcement. However, it may create excessive pressure, and discourage reliable clients from borrowing. Two randomized trials tested the overall effect, as well as specific mechanisms. The first removed group liability from pre-existing groups and the second randomly assigned villages to either group or individual liability loans. In both, groups still held weekly meetings. We find no increase in default and larger groups after three years in pre-existing areas, and no change in default but fewer groups created after two years in the expansion areas.

We then show that these two thermodynamical quantities satisfy complementary relation in the quantum-mechanical sense. It describes sharing of (quantum) information in the solid between spin entanglement and local properties of its individual constituents. Magnetic susceptibility is shown to be a macroscopic spin entanglement witness that can be applied without complete knowledge of the specific model (Hamiltonian) of the solid.

description: Capital gains taxes are likely to distort the market and resource allocations through so called “lock-in” effect, meaning discouraging trade transactions that trigger the tax payments. When it comes to agricultural land, the lock-in effect implies that the land ownership and active farming deviate from each other and, as a result, land tenancy increases. Increasing land tenancy and land tenure insecurity incur a significant social cost, because they deplete productivity of land by discouraging and delaying irreversible land improvements that would be necessary for maintaining land productivity. This study estimates the fiscal effects of reduction in capital gains taxes imposed on land sales and provides grounds for optimizing the tax scheme. The results suggest that certain temporary tax waiver programs could maintain the current tax revenues with less trade distorting effects on the land market. By simulating the land trade quantities conditional on alternative tax rates, the study gives information on how much a particular tax waiver program would trigger land sales. The results signal that tax waiver programs could shift the current structural development pattern of gradually increasing tenancy and land tenure insecurity to a pattern, in which the share of land ownership would be increased.

description: We report the discovery of four groups of galaxies along the line of sight to the B1608+656 gravitational lens system. One group is at the redshift of the primary lensing galaxy (z = 0.631) and appears to have a low mass, with eight spectroscopically-confirmed members and an estimated velocity dispersion of 150+/-60 km/s. The three other groups are in the foreground of the lens. These groups contain ~10 confirmed members each, and are located at redshifts of 0.265, 0.426, and 0.520. Two of the three additional groups are centered roughly on the lens system, while the third is centered ~1 arcminute south of the lens. We find that each group provides an external convergence (kappa_ext) of ~0.005--0.060, depending on the assumptions made in calculating the convergence. For lens systems where no additional observables that can break the mass-sheet degeneracy exist, the determination of H_0 will be biased high by a factor of (1-kappa_ext)^{-1} if the external convergence is not properly included in the model. For the B1608+656 system, the stellar velocity dispersion of the lensing galaxy has been measured, thus breaking the mass-sheet degeneracy due to the group that is physically associated with the lens. The effect of the other groups along the line of sight can be folded into the overall uncertainties due to large-scale structure (LSS) along the line of sight. Because the B1608+656 system appears to lie along an overdense line of sight, the LSS will cause the measurement of H_0 to be biased high for this system. The systematic bias introduced by LSS could be 5% or greater. (Abridged)

description: Dark matter stability can result from a residual matter-parity symmetry surviving spontaneous breaking of an extended gauge symmetry. We propose the simplest scotogenic dark matter completion of the original SVS theory (Phys.Rev. D22 (1980) 738), in which the "dark sector" particles as well as matter-parity find a natural theoretical origin in the model. We briefly comment on its main features.

description: The remnant G347.3-0.5 exhibits strong shell emission in the radio and X-ray bands, and has a purported detection in the TeV gamma-ray band by the CANGAROO-II telescope. The CANGAROO results were touted as evidence for the production of cosmic ray ions, a claim that has proven controversial due to constraining fluxes associated with a proximate unidentified EGRET source 3EG J1714-3857. HESS has now seen this source in the TeV band. The complex environment of the remnant renders modeling of its broadband spectrum sensitive to assumptions concerning the nature and parameters of the circumremnant medium. This paper explores a sampling of reasonable possibilities for multiwavelength spectral predictions from this source, using a non-linear model of diffusive particle acceleration at the shocked shell. The magnetic field strength, shell size and degree of particle cross-field diffusion act as variables to which the radio to X-ray to gamma-ray signal is sensitive. The modeling of the extant data constrains these variables, and the potential impact of the recent HESS detection on such parameters is addressed. Putative pion decay signals in hard gamma-rays resulting from hadronic interactions in dense molecular clouds are briefly discussed; the requisite suppression of the GeV component needed to accommodate the 3EG J1714-3857 EGRET data provides potential bounds on the diffusive distance from the shell to the proximate clouds.

Beyond-the-self purpose in early adolescents from low-income, racial and ethnic minority backgrounds: the role of emotions
Creators: name: Nayman, Samuel Joseph
Publisher: name: No Publisher Supplied
Year: 2021

description: Beyond-the-self (BTS) purpose, defined as "a stable and generalized intention to accomplish something that is at once meaningful to the self and of consequence to the world beyond the self" (Damon et al., 2003, p. 121) is associated with a variety of positive health and academic outcomes (e.g., Bronk & Finch, 2010; Yeager et al., 2014). There is currently a fledgling literature on the environmental and psychological factors that contribute to BTS purpose in youth, and less is known on this topic for students from low-socioeconomic status, racial and ethnic minority backgrounds (Sumner et al., 2018). Theoretical and empirical research suggest that positive emotions, such as gratitude, can serve to broaden attention and build personal resources for long-term survival and flourishing, whereas negative emotions, such as anxiety, narrow attention (Fredrickson, 2001). As such, it is reasonable to imagine that BTS purpose, which is other-oriented and broad in perspective, would be predicted by a combination of high levels of positive emotions and low levels of negative emotions. This study’s sample (N = 209) of middle school students was nearly evenly divided between males (50.2%) and females (49.8%). A majority of students received free lunch (70.3%). Additionally, a majority of students were Latinx (56.0%), with African American (17.7%), Asian (13.9%), and Caucasian (12.4%) students representing the remainder of the sample. All students were assigned to complete self-report measures of anxiety and gratitude in the fall of the 2015-2016 school year. In the spring of that same school year, students were assigned to complete self-report measures of BTS purpose as well as to write essays about their purpose in life. Hierarchical linear and logistic regressions were performed to determine if students' anxiety and gratitude scores predicted BTS purpose and if there was an interaction between the predictor variables. Results indicated that gratitude was statistically significantly associated with the self-report measures of BTS purpose and accounted for approximately 15% of the variance, whereas anxiety did not explain additional variance. Although this study does not reveal a causal relationship, this study does support the prediction that high levels of positive emotions in the form of gratitude are associated with BTS purpose. Given research that demonstrates the efficacy of gratitude-enhancing interventions (Wood et al., 2010), future experimental studies can help determine whether gratitude plays a causal role in the development of BTS purpose. If gratitude does in fact help build BTS purpose, schools would be wise to adopt such interventions.

description: Litchi is an important crop in the mountainous part of northern Thailand yet its profitability has declined during the last 15 years. The replacement of litchi fruit orchards for seasonal flowers and vegetables has external costs related to increased levels of soil erosion, pesticides, and irrigation water use. Using a combination of financial analysis and agent-based modeling, the paper ex-ante assesses the impact of four technologies—artificial flower induction, small-scale cooperative fruit drying, post-harvest treatments to extend the shelf-life of fresh fruits, and greater irrigation efficiency—in terms of profits, farm incomes, litchi acreage, soil erosion, and pesticide use. The model was calibrated to one watershed in Chiang Mai province where economic development has been rapid. Although each technology substantially increases the profitability of litchi growing, scenario analysis shows that this is not enough to stem the decline in litchi orchards in the study area. To achieve this, the innovations would have to be combined with an increase in the fresh fruit price from about 9 baht/kg at present to at least 12 baht/kg. The sensitivity of the results is tested for variations in the irrigation water supply and liquidity. We report about farmers’ discussions about these results and discuss the implications for other areas in northern Thailand.

description: Excerpt from the report Summary: Every fluid milk market regulated by a Federal milk order in Kansas, western Missouri, and Oklahoma uses an average of prices paid by unregulated plants as the basis, or as one of two or more alternative bases, for setting minimum prices to producers for reserve and surplus (Class II) milk. This study covers the practices of 33 unregulated milk processing plants in the area mentioned. It was made to determine (1) how accurately the announced paying prices reflect prices actually paid for ungraded whole milk f.o.b. the plants, and (2) the composition, size, characteristics, and effects of supplemental payments made in the form of premiums for quality and volume, patronage refunds, bonuses, hauling subsidies, etc.

description: Session-based recommendation nowadays plays a vital role in many websites, which aims to predict users' actions based on anonymous sessions. There have emerged many studies that model a session as a sequence or a graph via investigating temporal transitions of items in a session. However, these methods compress a session into one fixed representation vector without considering the target items to be predicted. The fixed vector will restrict the representation ability of the recommender model, considering the diversity of target items and users' interests. In this paper, we propose a novel target attentive graph neural network (TAGNN) model for session-based recommendation. In TAGNN, target-aware attention adaptively activates different user interests with respect to varied target items. The learned interest representation vector varies with different target items, greatly improving the expressiveness of the model. Moreover, TAGNN harnesses the power of graph neural networks to capture rich item transitions in sessions. Comprehensive experiments conducted on real-world datasets demonstrate its superiority over state-of-the-art methods.

description: Seasonal wage labour was rarely distinguished from the permanent one in farm-household models although it has sharply increased in developed countries. Therefore, we propose to endogenize the demand for this peculiar labour type and highlight the trade-offs for the various labour combinations on farms. We use data on fruit and vegetables farms drawn from the 2000 French agricultural census. We show that seasonal wage labour is a substitute for permanent wage employment, and doesn't entirely follow the seasonality of the agricultural activity: competition on the labour and product markets play a significant role in the employment of labour types.
