Abstract
The 2 mm Mapping Obscuration to Reionization with ALMA (MORA) Survey was designed to detect high-redshift (z ≳ 4), massive, dusty star-forming galaxies (DSFGs). Here we present two likely high-redshift sources, identified in the survey, whose physical characteristics are consistent with a class of optical/near-infrared (OIR)-invisible DSFGs found elsewhere in the literature. We first perform a rigorous analysis of all available photometric data to fit spectral energy distributions and estimate redshifts before deriving physical properties based on our findings. Our results suggest the two galaxies, called MORA-5 and MORA-9, represent two extremes of the “OIR-dark” class of DSFGs. MORA-5 (

Abstract
We study the production of very light elements (Z < 20) in the dynamical and spiral-wave wind ejecta of binary neutron star mergers by combining detailed nucleosynthesis calculations with the outcome of numerical relativity merger simulations. All our models are targeted to GW170817 and include neutrino radiation. We explore different finite-temperature, composition-dependent nuclear equations of state, and binary mass ratios, and find that hydrogen and helium are the most abundant light elements. For both elements, the decay of free neutrons is the driving nuclear reaction. In particular, ∼0.5–2 × 10−6
M
⊙ of hydrogen are produced in the fast expanding tail of the dynamical ejecta, while ∼1.5–11 × 10−6
M
⊙ of helium are synthesized in the bulk of the dynamical ejecta, usually in association with heavy r-process elements. By computing synthetic spectra, we find that the possibility of detecting hydrogen and helium features in kilonova spectra is very unlikely for fiducial masses and luminosities, even when including nonlocal thermodynamic equilibrium effects. The latter could be crucial to observe helium lines a few days after merger for faint kilonovae or for luminous kilonovae ejecting large masses of helium. Finally, we compute the amount of strontium synthesized in the dynamical and spiral-wave wind ejecta, and find that it is consistent with (or even larger than, in the case of a long-lived remnant) the one required to explain early spectral features in the kilonova of GW170817.
The Birth Mass Function of Population III Stars
Authors: Latif Muhammad A. , Whalen Daniel , Khochfar Sadegh 
Published: January 2022

Abstract
Population III stars ended the cosmic dark ages and began early cosmological reionization and chemical enrichment. However, in spite of their importance to the evolution of the early universe, their properties remain uncertain because of the limitations on previous numerical simulations and the lack of any observational constraints. Here, we investigate Population III star formation in five primordial halos using 3D radiation-hydrodynamical cosmological simulations. We find that multiple stars form in each minihalo and that their numbers increase over time, with up to 23 stars forming in one of the halos. Radiative feedback from the stars generates strong outflows, deforms the surrounding protostellar disk, and delays star formation for a few thousand years. Star formation rates vary with halo, and depend on the mass accretion onto the disk, the halo spin number, and the fraction of massive stars in the halo. The stellar masses in our models range from 0.1–37 M
⊙, and of the 55 stars that form in our models, 12 are >10 M
⊙ and most of the others are 1–10 M
⊙. Our simulations thus suggest that Population III stars have characteristic masses of 1–10 M

Revised Energy Levels of Atomic Lanthanum Considering Hyperfine Structure
Authors: Güzelçimen Feyza , Windholz Laurentius , Başar Gönül , Kröger Sophie 
Published: January 2022

Abstract
The experimental wavenumbers of 2118 spectral lines from calibrated Fourier transform (FT) spectra have been used to determine revised energy values of 405 fine structure levels of atomic lanthanum, 264 levels of even and 141 levels of odd parity, respectively. For the determination of the level energies a weighted global fit of the center-of-gravity (cg) wavenumbers of all 2118 spectral lines has been done. All lines have been classified previously by different spectroscopic methods and by different authors. In order to achieve high accuracy, the hyperfine (hf) structure was taken into account when determining the cg wavenumbers from the FT spectra. The total uncertainty for all revised energy levels lies below 0.007 cm−1. A compilation of all revised energy levels along with their hf structure data is given, as well as a list of the spectral lines used in this investigation.
EXPLORING THE RELATIONSHIPS BETWEEN EARLY CHILDHOOD IN-SERVICE TEACHERS' CLASSROOM MANAGEMENT AND SELF-REGULATION SKILLS
Authors: Akyar Begüm Canaslan , Tuncer Nuran 
Published: January 2022

<p>Self-regulation skills allow individuals to control emotions, behaviors, and thoughts. Teachers' management of their behaviors, emotions, and thoughts could impact their classroom management too. Thus, teachers' self-regulation and classroom management relationships were analyzed in the study. To date, emotional regulation was studied, but self-regulation has not been studied in classroom management context. The study was designed as a quantitative study. Two hundred forty-four early childhood in-service teachers participated in the study. Correlation tests were used to analyze gathering data. The study result shows that self-regulation skills and classroom management are not correlated. On the other hand, there is a relationship between all three sub dimensions of self-regulation (self-monitoring, self-evaluation, self-reinforcement) and classroom management skills. The study result suggests that the early childhood teachers' self-reinforcement is positively correlated with classroom management skills. In addition, self-evaluation and self-monitoring are negatively correlated with classroom management. The study recommends that the teachers could increase their classroom management skills with internal or external rewards. Furthermore, the teachers can use some standard grade scales to observe whether they have misconceptions about classroom management strategies objectively.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0957/a.php" alt="Hit counter" /></p>
IMPACT OF MACROECONOMIC BEHAVIOUR ON DEPOSIT MONEY BANK LIQUIDITY IN NIGERIA
Authors: Topbie Joseph Akeerebari , Ibiwari Fiberesima , Nwankwo Godgift Anyamaobi 
Published: January 2022

<p>According to Keynes (1936), money is the most liquid asset. Liquidity is an attribute to an asset. The more quickly an asset is converted into money the more liquid it is said to be. Purpose: this study was carried out to determine the long-run and short-run impact of macroeconomic behaviour as measured by money supply, exchange rate, real interest rate, and credit to the private sector on deposit money bank liquidity in Nigeria as measured by liquidity ratio; using annual time-series data ranging from 1990 to 2020. Methodology/Technique: the purpose of this study was achieved by the application of Autoregressive Distributed Lag Technique (ARDL) together with Augmented Dickey-Fuller and Phillip-Peron Tests. Findings: it was revealed that the liquidity ratio converged with 3.17% to long-run equilibrium after a shock to explanatory variables. It further displayed that the current level of money supply and real interest rate had a negative but significant impact on liquidity ratio, whereas, one-year lag and two-year lag of money supply, real interest rate, and exchange rat positively impacted liquidity ratio in both long-run and short-run. Conversely, it was revealed that one-year lag, two-year lag, and three-year lag of credit to the private sector had a negative and insignificant impact on liquidity ratio in the long-run, while it negatively and significantly impacted liquidity ratio in the short-run. Conclusion/Policy Recommendations: As a result of the findings, the study recommended that government policies that will enforce sustainable and efficient liquidity ratio be made feasible in the banking sector.</p><p> </p><p>JEL: E10; E20; E40</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0920/a.php" alt="Hit counter" /></p>
CRITICAL PEDAGOGY & ELT CLASSROOMS IN INDIA: SOME THOUGHTS
Authors: Rasheed Asma 
Published: January 2022

This paper examines critical pedagogy and English language teaching (ELT) to understand how a classroom may, or may not, incorporate both of these aspects in a productive manner. It begins with looking at a relatively different paradigm of education that emerged towards the end of the twentieth century, where ideas of knowledge economy and knowledge capitalism gain ground. It traces a changing field of ELT that argues for language teaching from the perspective of Gramscian hegemony and spontaneous grammars. The paper briefly surveys the concept of critical pedagogy starting with the work of Paulo Friere and various other scholars. It will then see how this concept works in ESL classrooms and contexts, using culture and local concerns from the lives of learners particularly from India.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0992/a.php" alt="Hit counter" /></p>

Published: January 2022

<p>During recent years, the task-based approach has been considered an effective methodology for teaching English as a foreign language. The term “task-based” appear in most of the learning activities in the classroom. It is clear that English teachers are being more interested in the use of task-based approach for most of English skills. They are making efforts to make lessons become more interesting and meaningful. Besides, the task-based assessment has been paid much attention by English teachers. Therefore, this paper aims at presenting the background of task-based approach, giving definition of learning tasks, illustrating task-based framework and identifying the roles of teachers and learners in task-based approach. In addition, it describes the assessment of task-based approach and making recommendation for language teachers relating to how to conduct task-based lessons effectively.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0988/a.php" alt="Hit counter" /></p>
