A transportation strategy for regional development
Creators: name: Ajayi, Peter Sunday
Publisher: name: University of British Columbia
Year: 2010

description: Regional development is currently a major concern of governments in the developing countries - Nigeria included. The basic emphasis of regional development in these countries is the improvement of "quality of life for all citizens as development progresses" (Federal Republic of Nigeria: Third National Development Plan, 1975 - 80, Lagos, 1975, p. 291). In order to achieve this objective, emphasis is usually placed on the rural sector of the economy - where a majority of the citizens still live and are employed. The improvement of this sector is also the focus of this study. There are many strategies which are capable, at least theoretically, of improving conditions in the rural areas but the main emphasis of this study is the development of rural transportation as a means of developing the rural areas. Transportation is viewed as a necessity in any human settlement as people and goods have to move from one place to the other, for economic, social and political purposes. The first objective of this study is the establishment of the relationship between transportation and rural development - i.e. that there is a rural demand for transportation. If this demand exists, what mode of transport is most likely to satisfy that demand? At present in Nigeria, roads seem to be dominating other modes because of its characteristics. In this study, transportation is not seen as the sole agent for rural development. For a transportation strategy to be successful, it has to be coordinated with other development strategies. The problem of providing adequate rural transportation is identified as an institutional one. The institutional framework within which transportation is provided in Nigeria is then examined and problems identified, especially those related to rural transportation construction and maintenance. Especially apparent in the deficiencies of the existing administrative structure is the lack of coordination which it permits This lack of coordination of transportation policies exists between different ministries of the same government and between different levels of government - i.e. both horizontally and vertically. For this lack of coordination, it seems that the rural'roads are the most vulnerable. In view of this institutional problem, a modification of the existing structure is recommended, which gives greater emphasis to the development and maintenance of local roads in conjunction with the development of other modes of transportation for the country. The major modification is in favour of reducing the existing responsibi1ities of Local Governments in road transportation construction. This implies that the Federal and State Governments would have to take more shares if all types of roads are to be developed - i.e. providing good transportation in the rural areas.
Regional demolition waste treatment capacity: a case study based on the identification of building selective deconstruction value chain’s stakeholders

description: The construction and demolition sector is a major contributor to waste generation, prompting European and national public authorities to adopt a waste management strategy based on circular economy (CE) principles. This strategy aims to promote the reuse and recycling of construction materials. A key prerequisite for this strategy is selective deconstruction, which allows for more efficient waste recovery by separating materials based on their treatment, reuse, recycling and landfill potential. Selective deconstruction involves a value chain that includes a range of stakeholders. This paper proposes a methodology for identifying the stakeholders involved in this value chain, from project owners to waste reclamation and recycling companies. This methodology is applied to the Lille European Metropolis (France – LEM) to estimate the Deconstruction Resources Treatment Capacity of this Region (DRTCR). Finally, this capacity is analysed in relation to the volume of resources generated by deconstruction, and to the objectives set by the circular economy strategy. Results demonstrate the importance of developing selective deconstruction at a local scale, and highlight the need for investment in this sector and potential of sustainable business.

description: Cities are facing the greatest challenge of their whole lifecycle: choosing their own destiny. Cities are the main contributors to climate change, as much of the excess carbon dioxide in the atmosphere comes from them. Understanding how cities can transform into “circular cities” is key to fostering change. However, empirical studies in this direction are still scant. In this paper, we address this research gap by answering the following research question: how are current “cities of waste” transitioning to “circular cities”?  We do so by means of an empirical study involving several stakeholders located in the town of Pavia (Northern Italy). We find that some actors have implemented virtuous circular economy (CE) practices; however, the transition to CE is overall conducted in a fragmented manner, with a lack of orchestration and planning among private actors as well as lack of synergies between private and public actors. We conclude our study by advancing future avenues of research, highlighting our theoretical and managerial contributions, and advancing policy implications.

How Differences in Motivation and Identification Shape Four Types of Student Experiences with Problem-Based Learning
Creators: name: Buus, Katrine
name: Møller Pedersen, Louise
Publisher: name: Journal of Problem Based Learning in Higher Education
Year: 2021

description: This article examines why students experience Problem-Based Learning (PBL) environments differently and discusses considerations for improving PBL environments to support a more diverse student population. Based on theoretical perspectives regarding motivation, identification, and learning, we present a new typology consisting of four types of students with distinctly different ways of creating motivation and identity in a PBL environment. While some principles in the examined PBL model motivate and validate certain types of students, the same principles can also challenge identification or result in demotivation among other types of students. Both results are important to consider when developing an inclusive PBL environment. The typology can serve as a theoretical framework for understanding, analysing, and discussing how and why students experience contemporary or new learning environments differently. Additionally, the typology provides a tool for organizations and teachers to motivate and validate students with different type characteristics and improve PBL practices accordingly.

description: This paper concerns a free boundary problem modeling tumor growth with angiogenesis and two time delays. The two delays represent the time taken for cells to undergo mitosis and modify the rate of cell loss because of apoptosis, respectively. We study the stability of stationary solutions and find that Hopf bifurcation occurs under some conditions, which extends the results of Xu. Furthermore, numerical simulations are performed to investigate the relationship among the rate of angiogenesis, two time delays and Hopf bifurcation.

Diffractive Electroproduction of rho and phi Mesons at HERA
Creators: name: The H1 Collaboration
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Diffractive electroproduction of rho and phi mesons is measured at HERA with the H1 detector in the elastic and proton dissociative channels. The data correspond to an integrated luminosity of 51 pb^-1. About 10500 rho and 2000 phi events are analysed in the kinematic range of squared photon virtuality 2.5 < Q^2 < 60 GeV^2, photon-proton centre of mass energy 35 < W < 180 GeV and squared four-momentum transfer to the proton |t| < 3 GeV^2. The total, longitudinal and transverse cross sections are measured as a function of Q^2, W and |t|. The measurements show a transition to a dominantly "hard" behaviour, typical of high gluon densities and small q\bar{q} dipoles, for Q^2 larger than 10 to 20 GeV^2. They support flavour independence of the diffractive exchange, expressed in terms of the scaling variable (Q^2 + M_V^2)/4, and proton vertex factorisation. The spin density matrix elements are measured as a function of kinematic variables. The ratio of the longitudinal to transverse cross sections, the ratio of the helicity amplitudes and their relative phases are extracted. Several of these measurements have not been performed before and bring new information on the dynamics of diffraction in a QCD framework. The measurements are discussed in the context of models using generalised parton distributions or universal dipole cross sections.

description: The aim of the deliverable 1.5. is to present a summary of the results obtained in the Round 2 of the test performance studies (TPS) organized by WP1 on six prioritized pests. Tests selection for each TPS was conducted following the “Common rules for selection of tests for TPS” and based on the “Weighted criteria for selection of tests for TPS”, both described in deliverable D1.1 (Minimum performance parameters to select tests for validation and selection of laboratories for TPS), while the list of selected tests for each TPS is available and explained in deliverable D1.3 (List of tests for validation - Round 2). TPS participants were selected following the “Common rules for selection of participants for TPS” and based on the “Criteria for selection of participants of TPS”, also both described in deliverable D1.1. For each of the six TPSs, the methodology used to perform the tests, the results of preliminary studies to select the tests, the results of the TPS and their thorough analysis and interpretation are described in corresponding TPS reports (supplementary information available upon request under confidentiality agreement). The validation data obtained during the six TPSs will be available in the validation section of the EPPO database on the diagnostic expertise. Main outcomes for each of the TPSs are highlighted as well as difficulties noticed during the organization process, which will improve organization of the future studies in the field of plant pests.

description: The simulation of quantum circuits using the tensor network method is very computationally demanding and requires significant High Performance Computing (HPC) resources to find an efficient contraction order and to perform the contraction of the large tensor networks. In addition, the researchers want a workflow that is easy to customize, reproduce and migrate to different HPC systems. In this paper, we discuss the issues associated with the deployment of the QuantEX quantum computing simulation software within containers on different HPC systems. Also, we compare the performance of the containerized software with the software running on bare metal.

description: In this paper we further develop the connection between tridiagonal pairs and the q-tetrahedron algebra $\boxtimes_q$. Let V denote a finite dimensional vector space over an algebraically closed field and let A, A^* denote a tridiagonal pair on V. For $0 \leq i \leq d$ let $θ_i$ (resp. $θ^*_i$) denote a standard ordering of the eigenvalues of A (resp. A^*). Fix a nonzero scalar q which is not a root of unity. T. Ito and P. Terwilliger have shown that when $θ_i = q^{2i-d}$ and $θ^*_i = q^{d-2i}$ there exists an irreducible $\boxtimes_q$-module structure on V such that the $\boxtimes_q$ generators x_{01}, x_{23} act as A, A^* respectively. In this paper we examine the case in which there exists a nonzero scalar c in K such that $θ_i = q^{2i-d}$ and $θ^*_i = q^{2i-d} + c q^{d-2i}$. In this case we associate to A,A^* a polynomial P and prove the following equivalence. The following are equivalent: (i) There exists a $\boxtimes_q$-module structure on V such that x_{01} acts as A and x_{30} + cx_{23} acts as A^*, where x_{01}, x_{30}, x_{23} are standard generators for $\boxtimes_q$. (ii) P(q^{2d-2} (q-q^{-1})^{-2}) \neq 0. Suppose (i),(ii) hold. Then the $\boxtimes_q$-module structure on V is unique and irreducible.

Il fantastico di essere donna: spose, massaie e madri nell'opera di Paola Masino

Year: 2014

description: L’articolo si propone di rintracciare il topos del corpo femminile perturbante nella narrativa di Paola Masino, le cui eroine in negativo ricoprono per lo più i ruoli banalissimi e prosaici di spose, massaie e madri. Se da un lato le metamorfosi del femminile si riducono nell’opera di questa autrice al loro grado zero – contro la varietà di apparizioni diaboliche ed epifanie angeliche che caratterizzano la rappresentazione della donna nella letteratura del fantastico e del soprannaturale –  dall’altro la scrittura che ne descrive le trasfigurazioni mette in scena una retorica della metafora e dell’allegoria che interpreta l’essere come caduta e il corpo come condanna e sofferenza della carne. Così come il corpo femminile appare martoriato dall’inchiesta sul male e sul peccato e dal processo intentato a quelle forme di potere che costringono la donna al sacrificio della propria vita e all’annullamento di sé, anche il corpo della scrittura, implodendo nell’accumulazione caotica delle sue figure, manifesta il rapporto tormentato che lega la scrittrice alla creazione artistica, fino alla competizione e alla rivalità con la divinità creatrice, maschile e paterna.

Huntington’s chorea and schizophrenia : amino acids in thalamus
Creators: name: Buchanan, Janet Ann
Publisher: name: University of British Columbia
Year: 2010

description: Amino acids and other ninhydrin-positive compounds were measured in post-mortem thalamus from 25 Huntington's choreics, 10 schizophrenics, 5 schizophrenic-like psychotics, and 23 controls dying without neurological disease. Gamma-aminobutyric acid (GABA) was significantly reduced in choreic thalami, in accord with deficiencies found in other brain regions choreics (Perry et al., 1973a,b). GABA was also significantly reduced in schizophrenic thalami, suggesting a biochemical link between these two diseases, and supporting the hypothesis of a defect in the GABA system in schizophrenia (Roberts, 1972). Homocarnosine, a GABA-containing dipeptide, was also low in choreic and 9 out of 10 schizophrenic thalami. One schizophrenic had extremely high homocarnosine. Glycerophosphoethanolamine was significantly elevated in Huntington's choreics, but not in schizophrenics. A number of other variables were considered for their potential influence on amino acid concentrations in thalamus. The majority of amino acids were found to rise in a significantly linear fashion in the interval 3 to 49 hours post-mortem, although other models might have described the change better. GABA, ornithine, histidine and tyrosine were found to decrease significantly with increasing age between 21 and 80 years, in controls. The effects of pre-mortem hypoxia, regional variation within the thalamus, and neuroleptic drug treatment could not be rigorously tested with these data. Neuroleptics were unlikely to have been the cause of group differences in GABA concentration, since they failed to deplete GABA in brain of chronically treated rats. On the other hand, bronchopneumonia and other causes of pre-mortem hypoxia could not be ruled out as potential contributers to reduced GABA in thalamus.

description: Medical progress and demographic changes will increase the future need of support and care in older adults. The use of robotic-based technologies may support older adults and relief the health system and caregivers. The authors provide results from two design case studies of applications that are designed for and with older adults and their caregivers to support both, their physical and cognitive activity. The authors conducted a pre-study, designed two applications, which were displayed and performed by the humanoid robot Pepper and evaluated them together with the participants in care-settings. The goal was to assess user experience and to explore effects of system usage on physical and socio-emotional conditions of older adults and their caregivers. Results indicate that the system seems to be able to initiate joyful interaction and that the Robot motivated and empowered participants to mimic movements that are embodied by the robot and displayed by the applications.

description: In the initial years of operation, experiments at the Relativistic Heavy Ion Collider (RHIC) have identified a new form of matter formed in nuclei-nuclei collisions at energy densities more than 100 times that of a cold atomic nucleus. Measurements and comparison with relativistic hydrodynamic models indicate that the matter thermalizes in an unexpectedly short time, has an energy density at least 15 times larger than needed for color deconfinement, has a temperature about twice the critical temperature predicted by lattice QCD, and appears to exhibit collective motion with ideal hydrodynamic properties - a "perfect liquid" that appears to flow with a near-zero viscosity to entropy ratio - lower than any previously observed fluid and perhaps close to a universal lower bound. However, a fundamental understanding of the medium seen in heavy-ion collisions at RHIC does not yet exist. The most important scientific challenge for the field in the next decade is the quantitative exploration of the new state of nuclear matter. That will require new data that will, in turn, require enhanced capabilities of the RHIC detectors and accelerator. In this report we discuss the scientific opportunities for an upgraded RHIC facility - RHIC II - in conjunction with improved capabilities of the two large RHIC detectors, PHENIX and STAR. We focus solely on heavy flavor probes. Their production rates are calculable using the well-established techniques of perturbative QCD and their sizable interactions with the hot QCD medium provide unique and sensitive measurements of its crucial properties making them one of the key diagnostic tools available to us.

description: We present a study of emission lines of small hydrocarbons C$_2$H and $c$-C$_3$H$_2$, and COMs precursors H$_2$CO and CH$_3$OH in order to better understand the possible chemical link between the molecular abundances and UV radiation field in photodissociation regions (PDRs). We study two PDRs around extended and compact HII regions with $G \leq 50$~Habings in the S235 star-forming complex. We find the highest abundances of both hydrocarbons on the edges of molecular clumps, while $c$-C$_3$H$_2$ is also abundant in the low-density expanding PDR around compact HII region S235\,A. We see the highest methanol column density towards the positions with the UV~field $G\approx 20-30$~Habings and explain them by reactive desorption from the dust grains. The $N_{\rm C_2H}/N_{\rm CH_3OH}$ ratio is lower by a factor of few or the order of magnitude in comparison with the Horsehead and Orion Bar PDRs. The ratio is similar to the value observed in hot corinos in the Perseus cloud. We conclude that ion-molecular and grain surface chemical routes rule the molecular abundances in the PDRs, and the PDRs inherit molecular abundances from the previous dark stage of molecular cloud evolution in spite of massive stars already emitting in optics.

description: Autonomous cars are the first major examples of Artificial Intelligence (AI) in everyday life. When cars are transformed into platforms new service relationships emerge between car companies and the car users. These relationships generate gains and catches for both parts related to how physical and non-physical resources are exchanged in the sharing economy; how integrity is negotiated; and how responsibility is delegated when AI enables the car to take over most of the driving. With a “car as a platform approach”, in this paper, we present a design fiction on ethical implications for citizens’ daily lives with autonomous cars.
The pleasure experience of low- and high anhedonic undergraduates
Creators: name: Douglas, Kathryn Ann
Publisher: name: University of British Columbia
Year: 2010

description: Some emotional and descriptive aspects of an imagined pleasure experience were examined for low- and high-anhedonic undergraduates. Subjects were classified into low-anhedonic or high-anhedonic on the basis of scores on the.Physical Anhedonia Scale (Chapman, Chapman, & Raulin, 1976). Emotional responses were derived from scores on the Differential Emotions Scale (Izard, Dougherty, Bloxom, & Kotsch, 1974) and included anxiety items. A factor analysis was conducted for each of the two scales used and factor scores were computed. Because males scored as significantly more anhedonic than females, analyses were conducted separately for 49 dependent measures: recall of pleasant situations, average rating of pleasantness, frequency of pleasant experiences, individual situation ratings of pleasantness (maximum of 10), factor scores for 12 emotion factors, and factor scores for 24 anhedonia factors. The overall T2 for both males and females was highly significant, suggesting that low-anhedonics of both sexes differ from high-anhe-donics in their report's "regarding their emotional and experiential concomitants of the pleasure experience. The precise source of the difference was not, however, discernible. The factor structures of both the Differential Emotions Scale and the Physical Anhedonia Scale are discussed. Although the structure of the Differential Emotions Scale clearly replicates the work of Izard et al. (1974), that of the Physical Anhedonia Scale failed to be consistent. The weaknesses of the latter instrument are discussed with reference to factor analytic study.

description: Accretion disks around supermassive black holes in active galactic nuclei produce continuum radiation at ultraviolet and optical wavelengths. Physical processes in the accretion flow lead to stochastic variability of this emission on a wide range of timescales. We measure the optical continuum variability observed in 67 active galactic nuclei and the characteristic timescale at which the variability power spectrum flattens. We find a correlation between this timescale and the black hole mass, extending over the entire mass range of supermassive black holes. This timescale is consistent with the expected thermal timescale at the ultraviolet-emitting radius in standard accretion disk theory. Accreting white dwarfs lie close to this correlation, suggesting a common process for all accretion disks.

description: In this paper we propose a revisitation of the topic of unique decodability and of some fundamental theorems of lossless coding. It is widely believed that, for any discrete source X, every "uniquely decodable" block code satisfies E[l(X_1 X_2 ... X_n)]>= H(X_1,X_2,...,X_n), where X_1, X_2,...,X_n are the first n symbols of the source, E[l(X_1 X_2 ... X_n)] is the expected length of the code for those symbols and H(X_1,X_2,...,X_n) is their joint entropy. We show that, for certain sources with memory, the above inequality only holds when a limiting definition of "uniquely decodable code" is considered. In particular, the above inequality is usually assumed to hold for any "practical code" due to a debatable application of McMillan's theorem to sources with memory. We thus propose a clarification of the topic, also providing an extended version of McMillan's theorem to be used for Markovian sources.

description: We identify a link between the glass transition and percolation of mobile regions in configuration space. We find that many hallmarks of glassy dynamics, for example stretched-exponential response functions and a diverging structural relaxation time, are consequences of the critical properties of mean-field percolation. Specific predictions of the percolation model include the range of possible stretching exponents $1/3 \leq β\leq 1$ and the functional dependence of the structural relaxation time $τ_α$ and exponent $β$ on temperature, density, and wave number.

A Sample Bias in Quasar Variability Studies

Year: 2021
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: When a flux-limited quasar sample is observed at later times, there will be more dimmed quasars than brightened ones, due to a selection bias induced at the time of sample selection. Quasars are continuously varying and there are more fainter quasars than brighter ones. At the time of selection, even symmetrical variability will result in more quasars with their instantaneous fluxes scattered above the flux limit than those scattered below, leading to an asymmetry in flux changes over time. The same bias would lead to an asymmetry in the ensemble structure function (SF) of the sample such that the SF based on pairs with increasing fluxes will be slightly smaller than that based on pairs with decreasing fluxes. We use simulated time-symmetric quasar light curves based on the damped random walk prescription to illustrate the effects of this bias. The level of this bias depends on the sample, the threshold of magnitude changes, and the coverage of light curves, but the general behaviors are consistent. In particular, the simulations matched to recent observational studies with decade-long light curves produce an asymmetry in the SF measurements at the few percent level, similar to the observed values. These results provide a cautionary note on the reported time asymmetry in some recent quasar variability studies.

description: Here, I overview one of the available techniques for the analysis of broad-band spectropolarimetric data, the Stokes QU-fitting. Since broad-band receivers have been installed at most radio facilities, the collection of radio data, both the total intensity and the linear polarization, is revealing interesting features in their spectra. The polarized light, and therefore its properties, i.e. the fractional polarization and the polarized angle, are now finally well sampled in wide wavelength ranges. The new complex behaviors revealed by the data can be studied using the Stokes QU-fitting, which consists of modeling the Stokes parameters Q and U using wavelength-dependent analytical models, available in the literature. This technique provides a very good diagnostic of the nature and structure of the magnetized plasma, with the possibility to identify complex structures, internal or external, of the source of study. A summary of the available and most used models describing the polarization behavior, is presented. Moreover, some of the most significant observational works which use this technique are also summarized.

description: Microcanonical Monte Carlo simulations of a polydisperse soft-spheres model for liquids and colloids have been performed for very large polydispersity, in the region where a phase-separation is known to occur when the system (or part of it) solidifies. By studying samples of different sizes, from N=256 to N=864, we focus on the nature of the two distinct coexisting phases. Measurements of crystalline order in particles of different size reveal that the solid phase segregates between a crystalline solid with cubic symmetry and a disordered phase. This phenomenon is termed fractionation.

Giant demagnetization effects induced by superconducting films

description: We show that a ferromagnetic (F) slab with the in-plane magnetization sandwiched between two superconducting (S) films experiences strong demagnetization effect due to the Meissner screening of the stray magnetic field by the superconductors. In the extreme case the transition of the S films from normal to the superconducting state can switch the demagnetization factor from 0 to 1 which is in a sharp contrast with the S/F bilayers where such transition affects the magnetic field inside the F film only slightly. The giant demagnetization effect is shown to be qualitatively robust against the decreasing of the superconducting film thickness and may provide a hint towards the explanation of the anomalously large ferromagnetic resonance frequency shift recently observed for the S/F/S structures [I.

description: We construct examples of free-by-cyclic hyperbolic groups which fiber in infinitely many ways over Z. The construction involves adding a specialized square 2-cell to a non-positively curved, squared 2-complex defined by labeled oriented graphs. The fundamental groups of the resulting complexes are hyperbolic, free-by-cyclic and can be mapped onto Z in infinitely many ways.

description: This paper introduces a hybrid feature selection and classification validation approach for anomaly detection to identify major failure root causes using supervised classification validation. The proposed method is tested on real industry datasets from the manufacturing injection moulding process. Results indicate that the SMOTE technique effectively generates a balanced dataset for the minority class in both testing and training subsets, thereby improving model accuracy without altering the raw data samples. Pearson's correlation emerged as the best feature selection method when compared to Decision Tree and Recursive Feature Elimination methods. Random Forest was identified as the optimal classification model for anomaly detection using the case study datasets. This hybrid feature selection approach demonstrates that the study results can be applied to identify major root causes, thereby improving the quality performance of the injection moulding process.

description: Federated averaging (FedAvg) is a popular federated learning (FL) technique that updates the global model by averaging local models and then transmits the updated global model to devices for their local model update. One main limitation of FedAvg is that the average-based global model is not necessarily better than local models in the early stage of the training process so that FedAvg might diverge in realistic scenarios, especially when the data is non-identically distributed across devices and the number of data samples varies significantly from device to device. In this paper, we propose a new FL technique based on simulated annealing. The key idea of the proposed technique, henceforth referred to as \textit{simulated annealing-based FL} (SAFL), is to allow a device to choose its local model when the global model is immature. Specifically, by exploiting the simulated annealing strategy, we make each device choose its local model with high probability in early iterations when the global model is immature. From extensive numerical experiments using various benchmark datasets, we demonstrate that SAFL outperforms the conventional FedAvg technique in terms of the convergence speed and the classification accuracy.

description: Some time ago, the infrared limit of the Abelian Chern-Simons-Proca theory was investigated. In this letter, we show how the Chern-Simons-Proca theory can emerge as an effective low energy theory. Our result is obtained by means of a procedure that takes into account the proliferation, or dilution, of topological defects presented in the system.

description: Learning user representations based on historical behaviors lies at the core of modern recommender systems. Recent advances in sequential recommenders have convincingly demonstrated high capability in extracting effective user representations from the given behavior sequences. Despite significant progress, we argue that solely modeling the observational behaviors sequences may end up with a brittle and unstable system due to the noisy and sparse nature of user interactions logged. In this paper, we propose to learn accurate and robust user representations, which are required to be less sensitive to (attack on) noisy behaviors and trust more on the indispensable ones, by modeling counterfactual data distribution. Specifically, given an observed behavior sequence, the proposed CauseRec framework identifies dispensable and indispensable concepts at both the fine-grained item level and the abstract interest level. CauseRec conditionally samples user concept sequences from the counterfactual data distributions by replacing dispensable and indispensable concepts within the original concept sequence. With user representations obtained from the synthesized user sequences, CauseRec performs contrastive user representation learning by contrasting the counterfactual with the observational. We conduct extensive experiments on real-world public recommendation benchmarks and justify the effectiveness of CauseRec with multi-aspects model analysis. The results demonstrate that the proposed CauseRec outperforms state-of-the-art sequential recommenders by learning accurate and robust user representations.
