Teachers\u27 Perspectives on Translanguaging as a Pedagogical Resource in Senior High School English Classes
Translanguaging has been documented in previous research as a pedagogical resource in language classrooms. However, the monolinguistic culture prevents the leveraging of this resource in language learning. In addition, despite the extensive research on translanguaging, its use as a pedagogical resource is limited, particularly in the Philippine context. This study explores teachersâ perspectives on translanguaging in Senior High School subjects where English is the medium of instruction. Findings from focus group discussions reveal that the participants leverage translanguaging as a resource to help students in knowledge construction, meaning-making, and problem-solving. This study concludes with implications for policymakers and language teachers who believe only English will help language learning
Asymptotic L1-decay of solutions of the porous medium equation to self-similarity
We consider the ïŹow of gas in an N -dimensional porous medium with initial density v0 (x) â„ 0. The density v(x, t) then satisïŹes the nonlinear degenerate parabolic equation vt = âv m where m > 1 is a physical constant. Assuming that (1 + , t). We prove that the L1 -distance decays at a rate t 1/((N+2)mâN) . Moreover, if N = 1, we obtain an explicit time decay for the Lâ distance at a suboptimal rate. The method we use is based on recent results we obtained for the Fokker-Planck equation [2], [3]
A Novel Faceted UTD Solver in Altair Feko for Antenna Placement Applications
2022 3rd URSI Atlantic and Asia Pacific Radio Science Meeting (AT-AP-RASC), , 30/05/2022-04/06/2022, , EspañaA new Faceted UTD solver as implemented in Altair Feko is introduced here. The solver is based on UTD (Uniform Theory of Diffraction) applied to planar and arbitrarily convex curved surfaces meshed with planar triangles. It is most suitable for antenna placement applications in the high frequency regime
Quantum Numbers for Excitations of Bose-Einstein Condensates in 1D Optical Lattices
The excitation spectrum and the band structure of a Bose-Einstein condensate
in a periodic potential are investigated. Analyses within full 3D systems,
finite 1D systems, and ideal periodic 1D systems are compared. We find two
branches of excitations in the spectra of the finite 1D model. The band
structures for the first and (part of) the second band are compared between a
finite 1D and the fully periodic 1D systems, utilizing a new definition of a
effective wavenumber and a phase-slip number. The upper and lower edges of the
first gap coincide well between the two cases. The remaining difference is
explained by the existence of the two branches due to the finite-size effect.Comment: 5 pages, 9 figure
Giant Gastroduodenal Duplication Cyst with Juxta-Pancreatic Communication
Enteric duplication cysts are rare congenital malformations with a low incidence and there are only a few reports in the literature. Their clinical presentation varies according to the location and the type of duplication. T heir overall prognosis is good if early surgical intervention is provided. We report a 2-month-old boy who presented with a case of a giant gastroduodenal duplication cyst with a juxta-pancreatic communication and was successfully treated surgically. It is imperative to be aware of this rare congenital malformation that can present clinically with a wide range of non-specific symptoms that can cause significant morbidity and mortality if the treatment is delayed
Long-time behaviour and phase transitions for the McKeanâVlasov equation on the torus
We study the McKean-Vlasov equation ât% = ÎČ â1â% + Îș â·(%â(W ? %)) , with periodic boundary conditions on the torus. We first study the global asymptotic stability of the homogeneous steady state. We then focus our attention on the stationary system, and prove the existence of nontrivial solutions branching from the homogeneous steady state, through possibly infinitely many bifurcations, under appropriate assumptions on the interaction potential. We also provide sufficient conditions for the existence of continuous and discontinuous phase transitions. Finally, we showcase these results by applying them to several examples of interaction potentials such as the noisy Kuramoto model for synchronisation, the KellerâSegel model for bacterial chemotaxis, and the noisy HegselmannâKrausse model for opinion dynamics
Efficient numerical calculation of drift and diffusion coefficients in the diffusion approximation of kinetic equations
In this paper we study the diffusion approximation of a swarming model given by a system of interacting Langevin equations with nonlinear friction. The diffusion approximation requires the calculation of the drift and diffusion coefficients that are given as averages of solutions to appropriate Poisson equations. We present a new numerical method for computing these coefficients that is based on the calculation of the eigenvalues and eigenfunctions of a Schršodinger operator. These theoretical results are supported by numerical simulations showcasing the efficiency of the method
Photoproduction total cross section and shower development
The total photoproduction cross section at ultra-high energies is obtained
using a model based on QCD minijets and soft-gluon resummation and the ansatz
that infrared gluons limit the rise of total cross sections. This cross section
is introduced into the Monte Carlo system AIRES to simulate extended
air-showers initiated by cosmic ray photons. The impact of the new
photoproduction cross section on common shower observables, especially those
related to muon production, is compared with previous results
Conspiracy beliefs, regulatory self-efficacy and compliance with COVID-19 health-related behaviors: The mediating role of moral disengagement
Although recent studies on the 2019 coronavirus disease (COVID-19) have highlighted the negative effects of moral disengagement on intentions to comply with COVID-19 containment measures, little is known about the mediating role of moral disengagement in the relationship between regulatory self-efficacy in complying with the containment measures, beliefs in conspiracy theories and compliance with COVID-19 health-related behaviors. Data were collected from 1164 young adults (women, N = 796; 68.4%; mean age 25.60 ± 4.40 years) who completed an online survey from 15th May to 22nd June 2021. Results of the multi-group path analyses indicated that higher beliefs in conspiracy theories were associated with lower compliance with COVID-19 health-related behaviors, whereas higher self-efficacy beliefs in complying with the containment measures were associated with higher compliance with COVID-19 health-related behaviors. Moral disengagement significantly mediated the associations between beliefs in conspiracy theories, regulatory self-efficacy, and compliance with COVID-19 health-related behaviors. Finally, the tested model was gender-invariant. Findings suggest that public health authorities and social care professionals should promote interventions aimed at improving regulatory self-efficacy, emphasizing the moral significance of respecting or ignoring the recommended COVID-19 measures (e.g., physical distance in public), and enhancing people's concern for the potential harms of their immoral actions
