description: Teachers are frequently involved in developing and evaluating treatments for problematic behaviors. Along with other members of the interdisciplinary team, they must determine the level of intrusiveness that a treatment may have on a student. Several factors that influence the intrusiveness of treatment procedures are described. These factors were used to develop a checklist that could be used systematically by teachers to evaluate the intrusiveness of treatments recommended by treatment teams. After the checklist was administered to a group of preservice teachers, it was found to be capable of discriminating among several treatment options described in a series of case vignettes. The implications of incorporating such a checklist into the design and implementation of treatments for problem behavior are discussed. Les enseignants sont souvent impliqués dans le développement et l’évaluation de traitements des problèmes de comportement. De concert avec d’autres membres d’une équipe interdisciplinaire, ils doivent déterminer dans quelle mesure un traitement est intrusif pour l’élève. L’article décrit plusieurs facteurs qui influencent le degré de discrétion des procédures. À partir de ces facteurs, on a dressé une liste de vérification dont pourraient se servir les enseignants de façon systématique pour évaluer à quel point les procédures recommandées par les équipes de traitement sont intrusives. La liste a été présentée à un groupe de stagiaires et s’est avérée capable de distinguer plusieurs options de traitement décrites dans une série de vignettes d’étude de cas. S’ensuit une discussion portant sur les conséquences d’incorporer une telle liste de vérification dans la conception et la mise en œuvre de traitements pour les problèmes de comportement.

description: We present the first open peer review module for open access repositories. The module, designed in this first stage for integration with DSpace repositories, enables any scholar to offer a qualitative and quantitative evaluation of any research object hosted in a compliant repository. Weighted reputation metrics are calculated for individual articles, reviews, authors and reviewers. An advanced search function allows repository users to filter or sort research objects based on their reputation or the number of positive reviews. The integration of peer review in repositories promotes open scholarship by enabling a direct and transparent collaboration between authors and reviewers, and produces novel metrics directly reflecting the perceived quality of a research work by expert peers, contrary to current available metrics that only indirectly account for quality through usage statistics. The open peer review module has already been installed in two major Spanish repositories (DIGITAL.CSIC, e-IEO) with promising initial results.

description: Accurately generating ground truth (GT) trajectories is essential for Simultaneous Localization and Mapping (SLAM) evaluation, particularly under varying environmental conditions. This study introduces a systematic approach employing a prior map-assisted framework for generating dense six-degree-of-freedom (6-DoF) GT poses for the first time, enhancing the fidelity of both indoor and outdoor SLAM datasets. Our method excels in handling degenerate and stationary conditions frequently encountered in SLAM datasets, thereby increasing robustness and precision. A significant aspect of our approach is the detailed derivation of covariances within the factor graph, enabling an in-depth analysis of pose uncertainty propagation. This analysis crucially contributes to demonstrating specific pose uncertainties and enhancing trajectory reliability from both theoretical and empirical perspectives. Additionally, we provide an open-source toolbox (https://github.com/JokerJohn/Cloud_Map_Evaluation) for map evaluation criteria, facilitating the indirect assessment of overall trajectory precision. Experimental results show at least a 30\% improvement in map accuracy and a 20\% increase in direct trajectory accuracy compared to the Iterative Closest Point (ICP) \cite{sharp2002icp} algorithm across diverse campus environments, with substantially enhanced robustness. Our open-source solution (https://github.com/JokerJohn/PALoc), extensively applied in the FusionPortable\cite{Jiao2022Mar} dataset, is geared towards SLAM benchmark dataset augmentation and represents a significant advancement in SLAM evaluations.

Perturbative renormalization factors and O(a^2) corrections for lattice 4-fermion operators with improved fermion/gluon actions

description: In this work we calculate the corrections to the amputated Green's functions of 4-fermion operators, in 1-loop Lattice Perturbation theory. One of the novel aspects of our calculations is that they are carried out to O(a^2) (a: lattice spacing). We employ the Wilson/clover action for massless fermions (also applicable for the twisted mass action in the chiral limit) and a family of Symanzik improved actions for gluons. Our calculations have been carried out in a general covariant gauge. Results have been obtained for several popular choices of values for the Symanzik coefficients. While our Green's function calculations regard any pointlike 4-fermion operators which do not mix with lower dimension ones, we pay particular attention to DF=2 operators, both Parity Conserving and Parity Violating (F: flavour). We compute the perturbative renormalization constants for a complete basis of 4-fermion operators and we study their mixing pattern. For some of the actions considered here, even O(a^0) results did not exist in the literature to date. The correction terms which we calculate are essential ingredients for minimizing the lattice artifacts which are present in non-perturbative evaluations of renormalization constants with the RI'-MOM method. Our perturbative results, for the matrix elements of DF=2 operators and for the corresponding renormalization matrices, depend on a large number of parameters: coupling constant, number of colors, lattice spacing, external momentum, clover parameter, Symanzik coefficients, gauge parameter. To make these results most easily accessible, we have included them in the distribution package of this paper, as an ASCII file named: 4-fermi.m; the file is best perused as Mathematica input. The main results of this work have been applied to improve non-perturbative estimates of the B_K-parameter in N_F=2 twisted mass lattice QCD.

A Gradient in Education Due to Health? Evidence from the Study of Health Behavior in School-Aged Children

Publisher: name: Alberta Journal of Educational Research
Year: 2011

description: Research exploring the relationship between education and health suggests that people with higher levels of schooling report better health. To emphasize health as a determinant of educational achievement, this article establishes a gradient in education by health among Canadian students. Using data from the 2006 Health Behaviour in School-aged Children (HBSC) study, the relationship between self-rated health and achievement is examined for 8,626 students from 131 schools. The variation of the gradient in education by health within and between schools suggests that increases in self-rated health are associated with increased achievement for students. Moreover, the within-school regression accounted for 2.7 % of the variation in achievement due to health, whereas the between-school regression slope accounted for 19.8% of the variation in achievement due to health. Inequalities in achievement associated with health were more pronounced between schools than within schools. Policy implications as they relate to the findings are discussed. La recherche portant sur le rapport entre l’éducation et la santé donne à penser que les gens les plus instruits se disent en meilleure santé. Afin de mettre en relief la santé comme facteur déterminant dans le niveau d’instruction, cet article développe une échelle liant le niveau de scolarité et la santé chez les élèves canadiens. Puisant dans des données de l’enquête sur les comportements liés à la santé chez les enfants d’âge scolaire (2006), nous examinons le rapport entre la santé et la scolarité telles que décrites par 8 626 élèves provenant de 131 écoles. La variation notée dans le rapport scolarité/santé à l’intérieur des écoles et entre elles donne à penser que plus l’état de santé déclaré est positif, plus le rendement est élevé chez les élèves. De plus, la régression au sein des écoles représente 2,7% de la variation dans le rendement attribuable à la santé, alors que la régression entre les écoles représente 19,8 % de la variation dans le rendement attribuable à la santé. Les inégalités dans le rendement associé à la santé étaient plus prononcées entre les écoles qu’au sein des écoles. Nous discutons des incidences sur la politique qui découlent de ces résultats.

Superfluidity in multicomponent fermions via the functional renormalization group

description: We reveal the critical properties of the phase transition towards superfluid order that has been proposed to occur in large spin fermionic systems. For this purpose, we consider the bosonic field theory for fluctuations of the complex skew-symmetric rank-2 tensor order parameter close to the transition. We then nonperturbatively determine the scale dependence of the couplings of the theory by means of the functional renormalization group. We established a fluctuation-induced first-order phase transition. In the weak-coupling regime the jump in the order parameter is small and a new phase occurs almost continuously, while in the strong one the discontinuity of the transition is well detectable.

description: We consider a class of lattice topological field theories, among which are the weak-coupling limit of 2d Yang-Mills theory and 3d Riemannian quantum gravity, whose dynamical variables are flat discrete connections with compact structure group on a cell 2-complex. In these models, it is known that the path integral measure is ill-defined because of a phenomenon known as `bubble divergences'. In this paper, we extend recent results of the authors to the cases where these divergences cannot be understood in terms of cellular cohomology. We introduce in its place the relevant {\it twisted} cohomology, and use it to compute the divergence degree of the partition function. We also relate its dominant part to the Reidemeister torsion of the complex, thereby generalizing previous results of Barrett and Naish-Guzman. The main limitation to our approach is the presence of singularities in the representation variety of the fundamental group of the complex; we illustrate this issue in the well-known case of two-dimensional manifolds.

Stable interaction-induced Anderson-like localization embedded in standing waves

description: We uncover the interaction-induced \emph{stable self-localization} of bosons in disorder-free superlattices. In these nonthermalized multi-particle states, one of the particles forms a superposition of multiple standing waves, so that it provides a quasirandom potential to localize the other particles. We derive effective Hamiltonians for self-localized states and find their energy level spacings obeying the Poisson statistics for Anderson-like localization. Surprisingly, we find that the correlated self-localization can be solely induced by interaction in the well-studied nonintegrable Bose-Hubbard models, which has been overlooked for a long time. We propose a dynamical scheme to detect self-localization, where long-time quantum walks of a single particle form a superposition of multiple standing waves for trapping the subsequently loaded particles. Our work provides an experimentally feasible way to realize stable Anderson-like localization in translation-invariant disorder-free systems.

description: Los cambios que el proceso de Bolonia ha impuesto en la educación universitaria no sólo atañen a la docencia sino también a organismos incluidos dentro de la propia institución cuya aportación en el proceso enseñanza-aprendizaje es vital para cumplir los requisitos exigidos. Entre ellos, la biblioteca universitaria y sus responsables ocupan un lugar central que los obliga a replantearse sus cometidos profesionales y a adoptar una metodología de trabajo que ayude a la adquisición de las competencias y habilidades que actualmente la sociedad demanda. Un primer paso para delimitar el nuevo rol del bibliotecario universitario consiste en analizar las percepciones que los docentes tienen sobre ellos y, de esta manera, planificar la necesaria e imprescindible colaboración entre ambos colectivos. Con ese objetivo, Utilizamos un Modelo Conceptual de las Relaciones entre Bibliotecarios –Biblioteca/Profesores para determinar cuáles son las variables más importantes o a que los profesores atribuyen mayor importancia en esa relación. Presentamos algunas de las causas de la tensión existente entre profesores y bibliotecarios. Realizamos un estudio de caso en el Instituto Universitario ISCTE-IUL analizado bajo una perspectiva descriptivo-correlacional. En este estudio utilizamos una metodología cualitativa, el Grupo de Discusión, y una metodología cuantitativa, la encuesta por cuestionario. Alcanzamos un grado de ajuste idóneo entre el Modelo y los datos (CMIN/DF=4.067) y el Modelo explica en el 58% de la disponibilidad de los profesores para colaborar con los bibliotecarios. Nuestro Modelo final permite confirmar las relaciones establecidas en el Modelo inicial y descubrir un conjunto de relaciones nuevas que contribuyen a conocer en mayor profundidad las dinámicas establecidas entre los distintos procesos socio-culturales (entendidos como variables del Modelo) implicados en las relaciones bibliotecarios/profesores, con el objetivo de identificar los determinantes en la disponibilidad de los primeros para colaborar con los segundos. El modelo nos permite concluir que el 14% de la disponibilidad de los profesores para colaborar con los bibliotecarios resulta de las características intrínsecas de los profesores (sexo, edad, departamento, grado académico, categoría profesional, antigüedad).

description: The dispersed fixed-delay interferometer (DFDI) represents a new instrument concept for high-precision radial velocity (RV) surveys for extrasolar planets. A combination of Michelson interferometer and medium-resolution spectrograph, it has the potential for performing multi-object surveys, where most previous RV techniques have been limited to observing only one target at a time. Because of the large sample of extrasolar planets needed to better understand planetary formation, evolution, and prevalence, this new technique represents a logical next step in instrumentation for RV extrasolar planet searches, and has been proven with the single-object Exoplanet Tracker (ET) at Kitt Peak National Observatory, and the multi-object W. M. Keck/MARVELS Exoplanet Tracker at Apache Point Observatory. The development of the ET instruments has necessitated fleshing out a detailed understanding of the physical principles of the DFDI technique. Here we summarize the fundamental theoretical material needed to understand the technique and provide an overview of the physics underlying the instrument's working. We also derive some useful analytical formulae that can be used to estimate the level of various sources of error generic to the technique, such as photon shot noise when using a fiducial reference spectrum, contamination by secondary spectra (e.g., crowded sources, spectroscopic binaries, or moonlight contamination), residual interferometer comb, and reference cross-talk error. Following this, we show that the use of a traditional gas absorption fiducial reference with a DFDI can incur significant systematic errors that must be taken into account at the precision levels required to detect extrasolar planets.

description: This study examined the relationships among students’ background information and their in-school and after-school literacy activities, as well as the relationships between students’ background and their views of the Ontario Secondary School Literacy Test (OSSLT). The results showed that students’ literacy activities could be grouped into three types: e-literacy, traditional literacy, and creative literacy. Furthermore, results showed that categorization of literacy activities depended on whether the activities were conducted in English or in another language. Gender predicted certain types of literacy activities. Compared with English-as-a-first-language (L1) students, English-as-a-second-language (L2) students’ background influenced more of their views of the test. Cette étude a porté sur les rapports, d’une part, entre les antécédents des élèves et leurs activités scolaires et parascolaires en matière d’alphabétisation et, d’autre part, entre ces renseignements généraux et la perception qu’ont les élèves du test provincial de compétence linguistique de l’Ontario (TPCL). D’après les résultats, il est possible de regrouper les activités d’alphabétisation des élèves en trois catégories : l’alphabétisation électronique, l’alphabétisation traditionnelle et l’alphabétisation créative. De plus, les résultats indiquent que la catégorisation des activités d’alphabétisation dépendait de la langue dans laquelle se déroulaient les activités (anglais ou autre). Le genre constituait une variable prédictive de certains types de ces activités. Les antécédents des élèves dont l’anglais était la langue seconde influençaient plus leur perception du TPCL que ceux des élèves pour qui l’anglais était la langue maternelle.

description: The collision energy dependence of the cross section and the transverse momentum distribution of dielectrons from the Breit-Wheeler process in heavy-ion collisions are computed in the lowest-order QED and found to be sensitive to the nuclear charge distribution and the infrared-divergence of the ultra-Lorentz boosted Coulomb field. Within a given experimental kinematic acceptance, the cross section is found to increase while the pair transverse momentum ($\sqrt{\langle p_{T}^{2} \rangle}$) decreases with increasing beam energy. We demonstrate that the transverse-momentum component of Weizsacker-Williams photons is due to the finite extent of the charge source and electric field component in the longitudinal direction. We further clarify the connection between the nuclear charge distribution and the kinematics of produced $e^+e^-$ from the Breit-Wheeler process, and propose a criterion for the validity of the Breit-Wheeler process in relativistic heavy-ion collisions. Following this approach we demonstrate that the experimental measurements of the Breit-Wheeler process in ultra-relativistic heavy-ion collisions can be used to quantitatively constrain the nuclear charge radius. The extracted parameters show sensitivity to the impact parameter dependence, and can be used to study the initial-state and final-state effects in hadronic interactions.

Violations of unidimensionality and local independence in measures intended as unidimensional : assessing levels of violations and the accuracy in unidimensional IRT model estimates
Creators: name: Rajlic, Gordana
Publisher: name: University of British Columbia
Year: 2019

description: The current study was motivated by psychological measures intended as unidimensional, in which violations of unidimensionality and local independence (LI) are present. Unidimensionality and LI are the assumptions of unidimensional IRT models, widely used in educational assessment and increasingly used in other fields of psychology and in social and health sciences. Providing more details about the relation between different levels of violations of the two assumptions and the accuracy in unidimensional IRT model estimates was the main goal of the current study. The second goal of the study was to investigate the utility of certain ways to provide recommendations and guidelines about the size of distortions in unidimensional model estimates at different levels of violations. Four indexes based on eigenvalues from exploratory factor analysis were examined for such a purpose. Deemed beneficial for the main purpose of the study, a multidimensional model consistent with a “locally dependent unidimensional model” and a particular research design, based on varying the strength of the relevant latent dimensions, were employed in the study to create conditions of violations of the two assumptions in measures intended as unidimensional. The results of the study demonstrated robustness of the unidimensional IRT model (i.e., 2PL IRT model) under a range of violations and provided more information about the conditions of robustness. A strong relation was demonstrated between the violations, as defined by the strength of local dependence (LD), and the size of the distortions in the item parameters estimation (e.g., correlation of 0.90 with bias in the item discrimination estimates). The item discrimination parameter was systematically overestimated. In relation to the person location parameter, overestimation at the low end of the latent trait and underestimation at the high end of the trait was found – with bias systematically increasing with decrease in the strength of the dominant dimension and with increase in the strength of LD. Regarding the use of eigenvalue-based indexes in predicting bias, mixed results were obtained (no value was demonstrated in relation to item parameters estimation and some value in relation to person location estimation). The utility of the model/design employed in the study was discussed.

description: This paper concerns the simultaneous reconstruction of a sound-soft cavity and its excitation sources from the total-field data. Using the single-layer potential representations on two measurement curves, this co-inversion problem can be decoupled into two inverse problems: an inverse cavity scattering problem and an inverse source problem. This novel decoupling technique is fast and easy to implement since it is based on a linear system of integral equations. Then the uncoupled subproblems are respectively solved by the modified optimization and sampling method. We also establish the uniqueness of this co-inversion problem and analyze the stability of our method. Several numerical examples are presented to demonstrate the feasibility and effectiveness of the proposed method.

description: Galaxy clusters have their unique advantages for cosmology. Here we collect a new sample of 10 lensing galaxy clusters with X-ray observations to constrain cosmological parameters.The redshifts of lensing clusters lie between 0.1 and 0.6, and the redshift range of their arcs is from 0.4 to 4.9. These clusters are selected carefully from strong gravitational lensing systems which have both X-ray satellite observations and optical giant luminous arcs with known redshift. Giant arcs usually appear in the central region of clusters, where mass can be traced with luminosity quite well. Based on gravitational lensing theory and cluster mass distribution model we can derive an Hubble constant independent ratio between two angular diameter distances. One is the distance of lensing source and the other is that between the deflector and the source. Since angular diameter distance relies heavily on cosmological geometry, we can use these ratios to constrain cosmological models. Meanwhile X-ray gas fractions of galaxy clusters can also be a cosmological probe. Because there are a dozen parameters to be fitted, we introduce a new analytic algorithm, Powell's UOBYQA (Unconstrained Optimization By Quadratic Approximation), to accelerate our calculation. Our result proves that this algorithm is an effective fitting method for such continuous multi-parameter constraint. We find an interesting fact that these two approaches are sensitive to $Ω_Λ$ and $Ω_{M}$ separately. Combining them we can get quite good fitting values of basic cosmological parameters: $Ω_{M}=0.26_{-0.04}^{+0.04}$, and $Ω_Λ=0.82_{-0.16}^{+0.14}$ .

description: Polymers containing nitrogen have attracted much attention in connection with their application to high energy density materials (HEDMs), in which energy is inherent in the triple bond. It is an interesting question whether such polymerized phases appear in the high-pressure phase of metal carbodiimide MCN$_2$, of which synthesis have been reported in recent years, but few studies have investigated the crystal structure at high pressure. We have adopted a structure search based on the genetic algorithm coupled with ab initio electronic structure calculations to investigate possible crystal structures that may appear in the high-pressure phase of BaCN$_2$. The structure search successfully reproduced the previously reported crystal structures in the lower pressure range. With confirmed reliability of its predictive ability, the genetic search further predicts a polymerized phase with Ima2 appearing at higher pressure above 42 GPa. The polymerized phase takes the structure of a linear network of CN$_3$ planar triangular units. It is understood that the anion site units CN$_2$, which are close to each other under high pressure, form covalent bonds directly with each other and stabilize the phase.

description: High-sensitivity shaken lattice interferometry (SLI) based sensors have the potential to provide deep space missions with the ability to precisely measure non-gravitational perturbing forces. This work considers the simulation of the OSIRIS-REx mission navigation in the vicinity of Bennu with the addition of measurements from onboard SLI-based accelerometers. The simulation is performed in the Jet Propulsion Laboratory's (JPL) Mission Analysis, Operations and Navigation Toolkit (MONTE) and incorporates OSIRIS-REx reconstructed trajectory and attitude data from the Navigation and Ancillary Information Facility (NAIF) database. The use of the reconstructed data from NAIF provides realistic true dynamical errors and JPL's MONTE software allows for a high-fidelity simulation of a nominal reference for the filter. The navigation performance and reduction of tracking and complex modeling enabled by the onboard SLI-based sensor are presented for two orbital phases of the OSIRIS-REx mission. Overall, the results show that the addition of SLI-based accelerometer measurements improves navigation performance, when compared to a radiometric tracking only configuration. In addition, results demonstrate that highly-precise accelerometer measurements can effectively replace at least one day of DSN passes over a three-day period, thereby reducing tracking requirements. Furthermore, it is shown that lower-fidelity surface force modeling and parameter estimation is required when using onboard SLI-based accelerometers.
