Collaborative digital writing and metacognitive knowledge in writing among TEFL students: the mediating role of online knowledge sharing

Previous studies indicate that metacognitive knowledge has a key role in learning and that collaborative learning and knowledge sharing may affect learners’ metacognition. As such, the present study set out to test a structural model of teaching English as a foreign language (TEFL) students’ collaborative digital writing, online knowledge sharing, and metacognitive knowledge in writing, and specifically to examine the hypothesis that online knowledge sharing mediates the effect of collaborative digital writing and metacognitive knowledge in writing. With the participants of 102 Iranian TEFL undergraduate students, a structural equation modeling (SEM) was employed to establish the structural model. The findings revealed the fitness of the structural model of relationships among the study variables. The results also confirmed the mediator role of knowledge sharing. The implications of the findings about knowledge sharing, attitude to collaborative digital writing, and metacognitive knowledge in writing are discussed.
Prospects for Plant-Based Meat: Current Standing, Consumer Perceptions, and Shifting Trends

Dietary habits have a substantial influence on both planet and individual health. High intake of animal products has significant negative effects on the environment and on human health; hence, a reduction in meat consumption is necessary. The transition towards plant-based meat (PBM) is one of the potential solutions for environmental and health issues. To achieve this goal, it is important to understand the dietary habits and demands of consumers. This review was designed with a focus on PBM alternatives, dietary shifts during the COVID-19 pandemic, the drivers of consumers’ perceptions in various countries, and the measures that can promote the shift towards PBM. The PBM market is predicted to grow with rising awareness, familiarity, and knowledge in the coming years. Companies must focus on the categories of anticipated benefits to aid consumers in making the switch to a diet higher in PBM alternatives if they want to win over the target market.
On the Transient Behavior of Ehrenfest and Engset Processes

Two classical stochastic processes are considered, the Ehrenfest process, introduced in 1907 in the kinetic theory of gases to describe the heat exchange between two bodies, and the Engset process, one of the early (1918) stochastic models of communication networks. In this paper we investigate the asymptotic behavior of the distributions of hitting times of these two processes when the number of particles/sources goes to infinity. Results concerning the hitting times of boundaries in particular are obtained. We rely on martingale methods; a key ingredient is an important family of simple nonnegative martingales, an analogue, for the Ehrenfest process, of the exponential martingales used in the study of random walks or of Brownian motion.
A Note on Inclusion Properties of Weighted Orlicz Spaces

In this paper we present sufficient and necessary conditions for the inclusion relationbetween two weighted Orlicz spaces which complete the Osan\c{c}liol result in 2014.One of the keys to prove our results is to use the norm of the characteristic functionsof the balls in $\mathbb{R}^n$.
Role of MRI in Evaluation of Injuries of Posterolateral Corner of the Knee

Background: In particular during extension, the posterolateral corner of the knee (PLC) acts as a substantial rotational and transitional stress resistor. The interplay of numerous overlapping structures creates the multi-compartment complicated sector known as the posterolateral corner. Objective: Assessment of conventional MRI role in posterolateral corner of the knee. Patients and Methods: The study was a cross-sectional study. It was conducted at the Radiodiagnosis Department, Zagazig University Hospitals during six months. It included 36 symptomatic patients with knee trauma before the MR examination. Their ages ranged from 21 to 53 years. Results: According to LCL pathology among the studied cases there were 16.7% intact, 33.3% with sprain, 25% with partial tear and 25% with compete tear. According to PT pathology there were 19.4% intact, 66.7% with sprain, 5.6% with partial tear and 8.3% with compete tear. According to BF pathology there were 94.4% intact and 5.6% with compete tear. According to ITB pathology; 94.4% intact and 5.6% with ITB friction syndrome. According to PFL pathology, 50% intact, 25% with sprain, 16.7% with partial tear and 3 (8.3%) with compete tear. There was remarkable variation between patients and healthy persons in LCL, PT, BF, ITB, and PFL lesions. Conclusion: We came to the conclusion that MRI offers a superb, in-depth assessment of the knee's posterolateral corner structures and lesions. Chronic posterolateral instability can be caused by an unsuspected posterolateral corner injury. To improve surgical care, suggestive imaging results should be quickly communicated with the orthopedic surgeon.
Communications in Mathematical Physics Asymptotics of Linear Waves and Resonances with Applications to Black Holes

We describe asymptotic behavior of linear waves on Kerr(–de Sitter) black holes and more general Lorentzian manifolds, providing a quantitative analysis of the ringdown phenomenon. In particular we prove that if the initial data is localized at frequencies ∼ λ 1, then the energy norm of the solution is bounded by O(λ1/2e−(νmin−ε)t/2) + O(λ−∞), for t ≤ C log λ, where νmin is a natural dynamical quantity. The key tool is a microlocal projector splitting the solution into a component with controlled rate of exponential decay and an O(λe−(νmin−ε)t ) + O(λ−∞) remainder. This splitting generalizes expansions into quasi-normal modes available in completely integrable settings. In the case of generalized Kerr(–de Sitter) black holes satisfying certain natural conditions, quasi-normal modes are localized in bands and satisfy a precise counting law.
The Mystery of Comets

In this book, one of the world's foremost authorities on comets takes us on a voyage of discovery from the earliest speculations on the meaning of comets to his own pioneering research into both the nature of comets and the mysteries of our solar system. Professor Whipple begins by examining the earliest observations and notions of comets from the first recorded observation by the Chinese in 2315 B.C. to the cosmogonies and mythologies of the Babylonians and the Mayans. He then carries us step by step from the exciting time when Sir Isaac Newton formulated the law of gravity and Edmund Halley made the first correct prediction of a comet's return, up to a heady glimpse of extraterrestrial exploits still to come - the space missions to Halley's comet and the first landing on a comet, tentatively planned for 1995. In so doing, he addresses basic but long elusive questions about comets: Where do they come from? Do they die? Why do some comets seemingly defy gravity? What is the landscape of a comet like? Why does the head of a comet change when it draws near the sun?
Analytic Cauchy problem for the $\mu$-Camassa-Holm equation and its non-quasilinear version

We solve the Cauchy problems for the $\mu$-Camassa-Holm integro-partial differential equation of Khesin-Lenells-Misio\l{}ek and its non-quasilinear version introduced by Qu-Fu-Liu in the complex-analytic framework. These equations have nonlocal nature at two levels: they involve a pseudo-differential operator of negative order and this operator is defined in terms of an integral of the unknown function. We prove unique solvability of the Cauchy problems and provide an estimate of the lifespan of the solutions. Our method is the Ovsyannikov type argument by Batrostichi-Himonas-Petronilho about a scale of Banach spaces of analytic functions, but the non-quasilinearity is dealt with in a different way from theirs. Indeed, we use a simple reduction which is just a nonlocal version of a classical trick.
Role of CXCL10 in Spinal Cord Injury

Spinal cord injury (SCI) results in acute inflammatory responses and secondary damages, including neuronal and glial cell death, axonal damage and demyelination, and blood-brain barrier (BBB) damage, eventually leading to neuronal dysfunction and other complications. C-X-C motif Chemokine Ligand 10 (CXCL10) is expressed after the injury, playing multiple roles in the development and progression of SCI. Moreover, the CXCL10 antagonist can restrict inflammatory immune responses and promote neuronal regeneration and functional recovery. In this review, we summarize the structure and biological functions of CXCL10, and the roles of the CXCL10 / CXCR3 axis in acute inflammatory responses, secondary damages, and complications during SCI, thus providing a potential theoretical basis by highlighting CXCL10 as a new potential drug target for the treatment of SCI.
GORENSTEIN HOMOLOGICAL PROPERTIES OF TENSOR RINGS

Let $R$ be a two-sided Noetherian ring, and let $M$ be a nilpotent $R$ -bimodule, which is finitely generated on both sides. We study Gorenstein homological properties of the tensor ring $T_{R}(M)$ . Under certain conditions, the ring $R$ is Gorenstein if and only if so is $T_{R}(M)$ . We characterize Gorenstein projective $T_{R}(M)$ -modules in terms of $R$ -modules.
Field patterns without blow up

Field patterns, first proposed by the authors in Milton and Mattei (2017 Proc. R. Soc. A 473 20160819), are a new type of wave propagating along orderly patterns of characteristic lines which arise in specific space-time microstructures whose geometry in one spatial dimension plus time is somehow commensurate with the slope of the characteristic lines. In particular, in Milton and Mattei (2017 Proc. R. Soc. A 473 20160819) the authors propose two examples of space-time geometries in which field patterns occur: they are two-phase microstructures in which rectangular space-time inclusions of one material are embedded in another material. After a sufficiently long interval of time, field patterns have local periodicity both in time and space. This allows one to focus only on solving the problem on the discrete network on which a field pattern lives and to define a suitable transfer matrix that, given the solution at a certain time, provides the solution after one time period. For the aforementioned microstructures, many of the eigenvalues of this   -symmetric transfer matrix have unit norm and hence the corresponding eigenvectors correspond to propagating modes. However, there are also modes that blow up exponentially with time coupled with modes that decrease exponentially with time. The question arises as to whether there are space-time microstructures such that the transfer matrix only has eigenvalues on the unit circle, so that there are no growing modes (modes that blow-up)? The answer is found here, where we see that certain space-time checkerboards have the property that all the modes are propagating modes, within a certain range of the material parameters. Interestingly, when there is no blow-up, the waves generated by an instantaneous disturbance at a point look like shocks with a wake of oscillatory waves, whose amplitude, very remarkably, does not tend to zero away from the wave front.
Representation of solutions of linear PDE's with constant coefficients as superpositions of solutions in lower dimensions

A unified approach to the representation of solutions of linear PDE's with constant coefficients in high dimensions in terms of solutions of the same PDE's in lower dimensions is presented. It is based on the observation that if a function of an (N+1)-dimensional variable (N * 2) has a convergent Fourier integral representation, then it may be written as a superposition of rotated plane waves in any number of dimensions lower than N+1. If that function is a solution of a linear PDE with constant coefficients, and, in addition, the equation is invariant under a spatial group of transformations (e.g., rotations, or Lorentz transformations), then the superposition is in terms of solutions of lower- (not only two-) dimensiuonal solutions of the same PDE. As examples, representations of solutions of the Laplace equation in (N+1) dimensions and of the wave equation in (1+N) dimensions (N * 2) as superpositions of solutions in lower dimensions are discussed, and simple consequences are presented.
A Survey of the Profiles of Narrow Emission Lines in Seyfert Galaxies

An atlas of the nuclear spectra of 58 Seyfert galaxies and six galaxies with nuclear H II regions is presented. For all but three galaxies, the range of rest wavelengths covered is about 6000-6800 A, with spectral resolution at H-alpha either 45 km/s or 130 km/s. Widths are given for the emission lines forbidden Fe VII 6086 A, forbidden O I 6300 A, H-alpha, forbidden N II 6584, and forbidden S II 6717,6731 A. In all, widths for some 210 lines in 53 galaxies are listed. A comparison is made between the present and previous line width measurements. 27 refs.
The proximity effect and the mean intensity of ionizing radiation at low redshifts

We report the first tentative detection of the proximity effect in the distribution of Lyα forest lines at low redshifts (z≤1). This is based on observations of 13 quasars by Bahcall et al. with the Faint Object Spectrograph on the Hubble Space Telescope as part of the Quasar Absorption Line Key Project. We estimate the mean intensity of ionizing radiation on the usual assumption that the proximity effect is caused entirely by the increased photoionization of absorbers near the quasars. The result is J L ∼6×10 −24 ergs s −1 cm −2 sr −1 Hz −1 at z≃0.5. However, the uncertainties are large, and even at the 1 σ level, J L could be lower by a factor of 3 or higher by a factor of 6
Water-Holding Properties of Clinoptilolite/Sodium Polyacrylate-Modified Compacted Clay Cover of Tailing Pond

Clinoptilolite and sodium polyacrylate (Na-PAA) were used as water-retaining agents to improve the water-holding capacity of compacted clay cover (CCC). The optimum moisture content and Atterberg limits of the CCC modified by clinoptilolite and Na-PAA were studied. The soil–water characteristic curve (SWCC) of the CCC modified by clinoptilolite and Na-PAA was studied. The mesostructure of the CCC was analyzed by polarized light microscopy. The test results show that: (1) the optimum moisture content and liquid limit of the CCC modified by clinoptilolite and Na-PAA increased, while the maximum dry density decreased; (2) the SWCC of the CCC modified by clinoptilolite and Na-PAA shifts to the upper right, and the volume moisture content of modified CCC is higher than that of unmodified CCC under the same matrix suction; (3) compared with the unmodified CCC, the air-entry value (AEV) of the clinoptilolite-modified CCC increased by 65.18% at most, and the AEV of the further modified CCC with Na-PAA in-creased by about two times; and (4) the flocculation structure and porosity of modified CCC decreased, and the porosity was distributed uniformly.
Monte Carlo algorithm for pricing options under stochastic volatility models

Monte Carlo (MC) simulation is a powerful technic to valuate option, but few literature discuss option pricing under stochastic volatility model (SVM). In this paper, we apply MC method to price European options under SVMs. Firstly, given correlative coefficient, a formula generating norm distribution random variables is established. Then, MC scheme is proposed for pricing European options under Heston, Hull-White and Hyper-geometric models. Numerical experiments illustrate the efficiency and accuracy of MC algorithm. With large number of simulated paths and time partition, MC solutions become stable. The proposed MC method can be extended to general option pricing, such as local stochastic volatility models and so on.
UDL Implementation in Higher Education: Drawing lessons from the COVID online pivot and reconnecting with inclusive design in the face-to-face classroom

After two decades of advocacy across North American campuses, it is fair to assert that Universal Design for Learning (UDL) is finally having an impact on the inclusion of students with disabilities across campuses (Schreffler et al., 2019). It is helping shift instructors and departments away from medical model approaches to students with disabilities (Edwards et al., 2022), and facilitating the adoption of the social model of disability in classroom practices (Fovet, 2014). In 2020, however, the COVID-19 pandemic forced campus closures and an overnight shift to online instruction and assessment across the world (Hodges et al, 2020). Many have argued that this pivot has helped increase awareness of accessibility and has developed inclusive design as a mindset among instructors (Dhawan, 2020). Equally numerous are researchers and practitioners who feel that the pandemic has weakened institutions’ commitment to inclusion, made accessible learning more difficult to achieve, and generally hindered the development of UDL in higher education (Napierala et al., 2022). This dichotomy in perspectives is pervasive and encountered in most jurisdictions; it demonstrates the need for higher educators to ‘reconnect’ despite these lived experiences and to journey collectively and collaboratively towards more inclusive practices, in this period of healing. This interactive session will lead the audience in assessing to what extent each of these assertions might be true, and how campuses can draw important lessons from these experiences, in relation to UDL implementation – particularly in Technology Enhanced Environments (TELs). It will examine how researchers and practitioners must draw from lessons learnt in online teaching and learning in these two disruptive years to ‘reconnect’ with the inclusive design mindset et advance UDL implementation as they return to the fade to face classroom. It will demonstrate how sometimes difficult and rushed reflections around inclusive design in TELs that occurred during the global health crisis, now have the potential to radically overhaul previous attitudes and assumptions, and to erode initial resistance to inclusive design as a mindset. The presentation draws from multiple interactive workshops which have been offered to UDL advocates and faculty throughout the pandemic. It presents the analysis of phenomenological data gathered throughout these professional development sessions.
Appropriateness of different rule types in speech synthesis

The Cornell Speech Research System has been augmented to support a third kind of rule. In addition to feature and parameter rules, the user can now express letter‐to‐sound rules. Feature rules modify the feature composition of an utterance, and parameter rules transform the output of the feature rules into a file of synthesizer parameters. Letter‐to‐sound rules convert standard orthography into a phonetic transcription. A powerful notation has been developed for expressing these rules. By using the system, we have found that the three kinds of rules can be written to interact in linguistically meaningful ways to yield speech.
Study the Impact of The Change of Water Quality in El Mahmoudia Canal on The Chemical Properties of The Agricultural Environment

Egypt is facing increasing in water needs because of increasing population therefore, keeping the suitable quality of fresh water streams, it is necessary for safe life and sustainability of all productivity sectors in Egypt. Degradation of water quality observed in the Mahmoudia Canal well water in both each its two sides. Therefore, this study aims to investigate the assessments of Micronutrients concentrations and chemical properties in soils, plant and wells in cultivated farms located in both sides of El Mahmoudia irrigation canal compared control area (uncultivated). The results showed that the all chemical parameters for both ground water (well water) and Mahmoudia water (surface water) were within recommended range of the standards (WHO and FAO) for agricultural use except Mn. Micronutrients levels in soil and plants samples were lower than the safe limits for human consumption. This high Mn levels in El Mahmoudia irrigation canal, Egypt may attribute to more Mining and Brick, fertilizers factories excess fertilization and pesticides, chemicals companies. Micronutrients concentrations in soil samples were all significantly different (P<0.05) compared to control (uncultivated) area. This shows that anthropogenic activities are the main cause of metal emission. The concentration of macronutrients for soils and plants analyzed in all parts are within the range set up by the standard.
Complex Random Matrices have no Real Eigenvalues

Let $\zeta = \xi + i\xi'$ where $\xi, \xi'$ are iid copies of a mean zero, variance one, subgaussian random variable. Let $N_n$ be a $n \times n$ random matrix with entries that are iid copies of $\zeta$. We prove that there exists a $c \in (0,1)$ such that the probability that $N_n$ has any real eigenvalues is less than $c^n$ where $c$ only depends on the subgaussian moment of $\xi$. The bound is optimal up to the value of the constant $c$. The principal component of the proof is an optimal tail bound on the least singular value of matrices of the form $M_n := M + N_n$ where $M$ is a deterministic complex matrix with the condition that $\|M\| \leq K n^{1/2}$ for some constant $K$ depending on the subgaussian moment of $\xi$. For this class of random variables, this result improves on the results of Pan-Zhou and Rudelson-Vershynin. In the proof of the tail bound, we develop an optimal small-ball probability bound for complex random variables that generalizes the Littlewood-Offord theory developed by Tao-Vu and Rudelson-Vershynin.
Generation of radial electric field induced by collisionless internal kink mode with density gradient

Effects of density gradient on the collisionless m=1 (m/n=1/1) internal kink mode in a cylindrical tokamak plasma are studied by the gyrokinetic particle simulations. When the density gradient is not large enough to change the full reconnection process, the phenomena after the full reconnection, such as the secondary reconnection and the evolution of the safety factor profile, are changed considerably due to the self-generated radial electric field, i.e., the m/n=0/0 mode. The growing mechanism is explained by the difference of E×B drift motion between ions and electrons, which is caused by the fast parallel motion of electron. Once the radial electric field is triggered by the symmetrical flow induced by the 1/1 mode, the 0/0 mode grows up to the same level as the 1/1 mode, and drives an E×B plasma rotation in the ion diamagnetic direction, which breaks the symmetrical plasma flow induced by the 1/1 mode. The density and current distributions, and therefore minimum safety factor qmin after the full recon.
Isometries on Banach algebras of vector-valued maps

We propose a unified approach to the study of isometries on algebras of vector-valued Lipschitz maps and those of continuously differentiable maps by means of the notion of admissible quadruples. We describe isometries on function spaces of some admissible quadruples that take values in unital commutative C *-algebras. As a consequence we confirm the statement of [14, Example 8] on Lipschitz algebras and show that isometries on such algebras indeed take the canonical form.
Time-varying system identification using wavelets

An algorithm for identifying time-varying AR and ARMAX models is proposed. Each model coefficient is expanded onto a wavelet basis and the expansion parameters are estimated. An F-test and an AIC based procedure are developed to discard the insignificant terms of the expansion and provide a description for the system's trajectory as well as its order. The choice of the optical wavelet basis for this problem is also discussed. The proposed method offers a parsimonious description of the system's trajectory, while still being able to 'zoom into' the local variations where necessary. <<ETX>>
