Published: February 2021

Abstract
Classroom management is cited as a frequent concern by many teachers. These concerns with classroom management are commonly rooted in a struggle to effectively engage students and a failure to form authentic relationships with students. Centering Culturally Relevant Pedagogy is crucial when effectively engaging and building authentic relationships with students – especially for Culturally and Linguistically Diverse students identified with Emotional Behavior Disorder (EBD). Mainly, teachers should hold a high self-efficacy of themselves and high expectations for their students, build and maintain authentic classroom communities, and demonstrate a passion for their work. Unfortunately, many teachers do not prioritize the need to be culturally responsive to their students’ families or the need to investigate their own cultural self-awareness. Additionally, these teachers often feel uninformed and ill-prepared to prioritize the aforementioned elements to successfully engage students in the classroom, as educator preparation programs often provide too little information, training, and reinforcement regarding the basics, as well as more specific strategies, of effective classroom management. Schools persistently fall short in providing an educational experience for students with EBD that leads to appropriate and desired educational outcomes due to a lack of teacher training in understanding the foundation and function of behavior, as well as how to appropriately address problematic behaviors. These shortcomings become particularly complex in classrooms with students with EBD, given the students’ multifaceted academic and social behavioral needs. Moreover, given the overrepresentation of African American males in the EBD disability category, the importance of specific cultural components cannot be ignored. Thus, when teachers do not structure their classroom culture in a manner that is Culturally Relevant, many students, especially African American male students with EBD, experience challenges meeting their goals to function properly in various environments—both in and out of the classroom. One strategy that teachers can use to improve their teaching of students with EBD is Classroom Management On-boarding (CMO-b). This paper identifies specific techniques that could guide the development of a plan for CMO-b that emphasizes the importance of the teacher-student relationship as the foundation for building a positive and effective classroom for teachers of students identified with EBD, and especially for African American male students.

Abstract
Cupric oxide (CuO), as a transition metal oxide (TMO) semiconductor, has attracted tremendous attention for various applications. In the present work, we synthesize the CuO nanosheets modified by TiO2 nanoparticles via a facile, non-toxic two-step method. Subsequently, the morphology and the structures of CuO and TiO2/CuO nanocomposites are investigated. By utilizing the common Z-scan technology, broadband nonlinear optical (NLO) properties of the as-prepared CuO nanosheets and TiO2/CuO nanocomposites are demonstrated, elucidating the enhancement on the NLO response via the TiO2 dopant, which is attributed to the more oxygen vacancies and the formed p-n junctions. Furthermore, CuO nanosheets and TiO2/CuO nanocomposites are implemented to the passively Q-switched bulk lasers operating in the near-infrared (NIR) region, generating broadband ultrastable pulses. Ultimately, TiO2/CuO nanocomposites were intergrated in a passive mode-locking bulk laser for the first time, achieving stable mode-locked pulses and verifying its ultrafast optical response potential. Our results illustrate the tremendous prospects of the CuO nanosheets modified by oxygen vacancy engineering as a broadband NLO material in ultrafast photonics field.

The Government and Civil Society Collaboration against COVID-19 in South Korea: A Single or Multiple Actor Play?
Authors: Jeong Bok Gyo , Kim Sung-Ju 
Published: February 2021

AbstractThis study examines, from a collaborative governance perspective, the public policy process of South Korea in responding to the global health pandemic. In many countries, attention has been focused primarily on governmental capacity and political leadership in containing the COVID-19 pandemic. In South Korea, however, the role of civil society as a collaborative partner to government is especially important. To analyze the comprehensive and substantive nature of government-civil society collaboration, this study assesses the response to COVID-19 along two dimensions: the level of civil society involvement in governance, and the stage in public policy development. The study reveals that the South Korean government was a coordinator of multiple actors and multiple sectors of society, including civil society, and that all three facets of civil society as described by Edwards (2004), were involved: associational life, civility, and engagement in the public sphere.

Published: February 2021

Abstract
Oxidative desulfurization is a promising way to produce, under mild conditions, clean ecological fuels with ultra-low sulfur content. Herein, we present for the first time heterogeneous catalysts based on natural aluminosilicate nanotubes (halloysite) loaded with transition metal oxides for oxidative sulfur removal using hydrogen peroxide as environmentally safe oxidant. The halloysite nanotubes (HNTs) provide acid sites for C–S bond scission, while the Mo and W oxides act as hydrogen peroxide activators. The structure and acidity of both the clay support and catalysts were investigated by low-temperature nitrogen adsorption/desorption, Fourier-transform infrared spectroscopy, X-ray fluorescence analysis, and transmission electron microscopy techniques. These clay-based catalysts revealed the high activity in the oxidation of various classes of sulfur-containing compounds (sulfides, heteroatomic sulfur compounds) under mild reaction conditions. The conversion of various substrates decreases in the following trend: MeSPh > Bn2S > DBT > 4-MeDBT > BT, which deals with substrate electron density and steric hindrance. The influence of the temperature, oxidant to sulfur molar ratio, and reaction time on catalytic behavior was evaluated for Mo- and W-containing systems with various metal content. The complete oxidation of the most intractable dibenzothiophene to the corresponding sulfone was achieved at 80 °C and H2O2:S = 6:1 (molar) for 2 h both for Mo- and W-containing systems. These transition metal oxides HNTs supported catalysts are stable for 10 cycles of dibenzothiophene oxidation, which makes them promising systems for clean fuel production.
Determination of trace uranium in thorium matrix by laser induced fluorimetry after separation of thorium by its fluoride precipitation using NH4HF2
Authors: Pradhan Susanta Kumar , Ambade Balram 
Published: February 2021

Abstract
Thorium, a major element in thorium matrix, quenches uranium fluorescence when it is present above the ratio (Th/U) of 2000 in conventional pellet fluorimetry determination of uranium. A single step ‘sample digestion cum thorium fluoride precipitation’ with NH4HF2 has been developed for separation of bulk thorium as hydrated thorium fluoride precipitates. Uranium in aqueous solution is extracted into ethyl acetate and stripped into pyrophosphate medium (pH ∼ 7), prior to its laser induced fluorimetry determination. Optimizations of certain parameters such as the effects of fluoride flux, mineral acid, temperature and time, stripping solution, diverse ions etc. are discussed in detail. The method has been validated by analyzing a set of synthetic mixtures and certified reference materials of rock samples such as SY-2, SY-3, GSP-2, NKT-1 and CG-2 doped with a large excess of thorium. This method has been applied for the determination of microgram to nanogram uranium in thorium rich rocks and synthetic nuclear grade ThO2 with high degree of accuracy and precision. This is the improvement of the existing method which involves two liquid-liquid solvent extraction separation of thorium and uranium using the chelating agent 2,3-dihydroxynaphthalene at the different pH, compared to one solvent extraction separation of uranium in the present method, because separation of thorium by precipitation as its fluoride has already been carried out during sample digestion step itself. The proposed method involving ammonium hydrogen fluoride in combination with laser induced fluorimetry is simple, rapid, cost effective and more eco-friendly.
Chemical effect on muonic atom formation through muon transfer reaction in benzene and cyclohexane samples

Published: February 2021

Abstract
To investigate the chemical effect on the muon capture process through a muon transfer reaction from a muonic hydrogen atom, the formation rate of muonic carbon atoms is measured for benzene and cyclohexane molecules in liquid samples. The muon transfer rate to carbon atoms of the benzene molecule is higher than that to the carbon atoms of the cyclohexane molecule. Such a deviation has never been observed among those molecules for gas samples. This may be because the transfers occur from the excited states of muonic hydrogen atoms in the liquid system, whereas in the gas system, all the transfers occur from the 1s (ground) state of muon hydrogen atoms. The muonic hydrogen atoms in the excited states have a larger radius than those in the 1s state and are therefore considered to be affected by the steric hindrance of the molecular structure. This indicates that the excited states of muonic hydrogen atoms contribute significantly to the chemical effects on the muon transfer reaction.
Home environmental interventions for prevention of respiratory tract infections: a systematic review and meta-analysis
Authors: Kua Kok Pim , Lee Dr. Shaun Wen Huey 
Published: February 2021

Abstract

Objectives
Poor housing conditions have been associated with increased risks of respiratory infections. This review aims to determine whether modifying the physical environment of the home has benefits in reducing respiratory infections.

Content

We performed a systematic review and meta-analysis of the effectiveness of home environmental interventions for preventing respiratory tract infections. Ten electronic databases were searched to identify randomized controlled trials published from inception to July 31, 2020. Random-effects meta-analyses were used to assess the study outcomes. Our search identified 14 eligible studies across 12 countries, which comprised 87,428 households in total. The type of interventions on home environment included kitchen appliance and design, water supply and sanitation, house insulation, and home heating. Meta-analysis indicated a potential benefit of home environmental interventions in preventing overall respiratory tract infections (Absolute RR=0.89, 95% CI=0.78–1.01, p=0.07; Pooled adjusted RR=0.72, 95% CI=0.63–0.84, p<0.0001). Subgroup analyses depicted that home environmental interventions had no significant impact on lower respiratory tract infections, pneumonia, and severe pneumonia. A protective effect against respiratory infections was observed in high income country setting (RR=0.82, 95% CI=0.78–0.87, p<0.00001).

Summary and outlook

Home environmental interventions have the potential to reduce morbidity of respiratory tract infections. The lack of significant impact from stand-alone housing interventions suggests that multicomponent interventions should be implemented in tandem with high-quality health systems.

Authors: Sasireka Krishnan Sundarrajan , Lalitha Pottail 
Published: February 2021

Abstract
The current advancements in nanotechnology suggest a sustainable development in the green synthesis of bimetallic nanoparticles (BMNPs) through green approaches. Though challenging, nano phyto technology has versatile methods to achieve desired unique properties like optic, electronic, magnetic, therapeutic, and catalytic efficiencies. Bio-inspired, facile synthesis of bifunctional BMNPs is possible using abundant, readily available natural plant sources, bio-mass wastes and microorganisms. Synergistic effects of two different metals on mixing, bring new insight for the vast applications, which is not achievable in using monometallic NPs. By adopting bio-inspired greener approaches for synthesizing NPs, the risk of environmental toxicity caused by conventional physicochemical methods become negligible. This article hopes to provide the significance of cost-effective, one-step, eco-friendly and facile synthesis of noble/transition bimetallic NPs. This review article endows an overview of the bio-mediated synthesis of bimetallic NPs, classifications of BMNPs, current characterization techniques, possible mechanistic aspects for reducing metal ions, and the stability of formed NPs and bio-medical/industrial applications of fabricated NPs. The review also highlights the prospective future direction to improve reliability, reproducibility of biosynthesis methods, its actual mechanism in research works and extensive application of biogenic bimetallic NPs.

Abstract
Spinal cord injury (SCI) is a debilitating condition which often leads to a severe disability and ultimately impact patient’s physical, psychological, and social well-being. The management of acute SCI has evolved over the couple of decades due to improved understanding of injury mechanisms and increasing knowledge of disease. Currently, the early management of acute SCI patient includes pharmacological agents, surgical intervention and newly experimental neuroprotective strategies. However, many controversial areas are still surrounding in the current treatment strategies for acute SCI, including the optimal timing of surgical intervention, early versus delayed decompression outcome benefits, the use of methylprednisolone. Due to the lack of consensus, the optimal standard of care has been varied across treatment centres. The authors have shed a light on the current updates on early treatment approaches and neuroprotective strategies in the initial management of acute SCI in order to protect the early neurologic injury and reduce the future disability.
How Saussure is misinterpreted in Cognitive Grammar
Authors: Zhang Yanfei , Zhang Shaojie 
Published: February 2021

AbstractAs the father of modern linguistics, Ferdinand de Saussure influences all aspects of linguistic development with no exception of Cognitive Grammar. A scrutiny of how Saussure is understood in Cognitive Grammar indicates that Saussurean linguistics is misinterpreted in terms of five core ideas: (1) langue, rather than parole, is given highest priority; (2) the internal relation of “signifier-signified” counts as the pairing of “form-meaning”; (3) “arbitrariness” is contradictory to “symbolicity”; (4) “arbitrariness” means “unmotivatedness”; (5) arbitrariness is not the inherent nature of morphological and syntactic structures. This paper is intended to reassess these five ideas and argue that they depart further from Saussure’s thought.
Visual affect in films: a semiotic approach
Authors: Jing Yi 
Published: February 2021

Abstract
This study investigates affective meanings expressed in facial expressions and bodily gestures from a semiotic perspective. Particularly, the study focuses on disentangling relations of affective meanings and exploring the meaning potential of facial expressions and bodily gestures. Based on the analysis of over three hundred screenshots from two films (one animation and one live-action film), this study proposes a system of visual affect, as well as a system of visual resources involved in the expression of visual affect. The system of visual affect makes a further step in the investigation of affective meanings afforded by facial expressions and bodily gestures, and can provide methodological insights into the examination of affective meanings expressed visually. The system of visual resources provides a more meaning-motivated framework for systematic tracking of the visual resources, which may be applied to the analysis of other visual media apart from films.
Modelizing epistemologies: organizing Catholic sanctity from calendar-based martyrologies to today’s mobile apps
Authors: Ponzo Jenny , Marino Gabriele 
Published: February 2021

AbstractThe Catholic concept of “sanctity” can be thought of as a “cultural unit” (Eco) composed of a wide variety of “grounds” (Peirce) or distinctive features. The figures of individual saints, i.e., tokens of sanctity, are characterized by a particular set of grounds, organized and represented in texts of different genres. This paper presents a semiotic study of texts seeking to offer an encompassing view of “sanctity” by listingallthe saints and supplementing their names with a short description of their lives emphasizing the grounds characterizing each of them. The analysis focuses on a seminal liturgical text, theMartyrologium Romanun(1584–2004), and the first official encyclopedia of saints, theBibliotheca Sanctorum(1961–2013), as well as a sample of digital texts and media such as websites and mobile apps. While the first text offers a dogmatic perspective on sanctity and saintly figures and the second offers a historical and culturological one, websites succeed in reconciling the two paradigms into a single syncretic form of interactive fruition in which the more up-to-date encyclopedic model subsumes the traditional calendar one and, in the case of apps, adds aglocaldimension, enhancing situated cognition. The analysis shows that the introduction of the encyclopedic genre and subsequent proliferation of digital repertoires is connected to a shift in the Catholic “episteme” (Foucault) of sanctity and a growing tendency to consider saints as not (only) religious characters and objects of cult, but (also) as historical individuals and components of a culture and, consequently, as suitable objects of critical discourse.
Construction of risk in road safety advertising: a multimodal analysis of Vietnamese child helmet awareness advertisements
Authors: Nguyen Hoang van 
Published: February 2021

Abstract
The discourses of risk serve to organise the ways in which we understand and respond to potential harms and threats, which have become a major concern in our daily life. However, the discourses of risk have not been extensively investigated using linguistic text-based methods on the multimodal level, nor deeply examined beyond Western contexts. Grounded in the literature of risk and multimodal discourse, the aim of the study is to demonstrate Multimodal Discourse Analysis from a Systemic Functional Linguistics perspective as a potential methodology to investigate how risk discourses are constructed in and through semiotic resources in a non-Western setting. Through a case study of child helmet awareness advertisements in Vietnam, the multimodal analysis reveals a comprehensive picture of risk discourses constructed across various semiotic modes. In this analysis, the discourses of risk are constructed through a negotiation of expert knowledge and traditional values to encourage the audience to take actions and provide helmets for their children. Findings of the study demonstrate the use of Systemic Functional multimodal approach to media and communication to provide evidence for risk discourses in the Vietnamese setting, which are at odds with the current literature and can potentially be extended to other contexts.
