    According to the Ministry of Finance's roadmap for applying IFRS in Vietnam, listed enterprises on the stock market and state-owned enterprises holding the dominant power are the first group of enterprises to alter the preparation of financial statements according to Vietnamese Accounting Standards (VAS) to the application of International Financial Reporting Standards (IFRS). The voluntary application period is from 2022 to 2025 and the period after 2025 will be the mandatory one. This study was conducted to determine the factors affecting the transition from preparing financial statements following VAS to IFRS for this group of enterprises. The study involved surveying managers and chief accountants at 120 enterprises belonging to the group of companies listed on the stock market, state-owned enterprises holding the dominant power, with the adoption of a regression analysis method. The research results show that five factors are affecting the transition of financial reporting from VAS to IFRS in this group of enterprises, with the order of influence being ranked from high to low, respectively as (i) Size and operation characteristics of the enterprise; (ii) Competence of accountants; (iii) Viewpoints of the enterprise administrators; (iv) Applied accounting regime, and (v) Enterprise owners. On that basis, the study proposes some recommendations for the transition from preparing financial statements according to VAS to IFRS for enterprises to meet the Ministry of Finance's roadmap for IFRS application.

    In order to increase the optical features of white light-emitting diodes (WLEDs), quantum dots (QDs) and phosphor materials have been proposed because of outstanding performance. The configuration of WLEDs with QDs layer and phosphor-silicone layer suggested placing these components separately to limit light loss, and enhance consistency at contact surface of QDs. In this research, the effects of QDs and phosphor on the performance of WLEDs are concluded through experiments. The emitted light and PL spectra were examined thoroughly, and infrared thermal imagers were applied to simulate the heat generation of an actual WLED device. The results show that with the configuration of 60 mA energy source, WLEDs which has the QDs-on-phosphor form attained luminous efficiency (LE) of 110 lm/W, with color rendering index (CRI) of Ra=92 and R9=80, whereas the WLEDs which has the phosphor-on-QDs form only has 68 lm/W in LE, Ra=57 and R9=24. Furthermore, WLEDs which has the QDs-on-phosphor form has less high temperature generated at the components’ conjunction in comparison to the counterpart, the peak generated heat in QDs-on-phosphor WLEDs is also lower and the heating capacity gap between 2 structures can go up to 12.3°C.

    Instructional Scaffolding in STEM Education
    ( 2017)
    Brian R. Belland
    This book uses meta-analysis to synthesize research on scaffolding and scaffolding-related interventions in STEM (science, technology, engineering, and mathematics) education. Specifically, the volume examines the extent to which study quality, assessment type, and scaffolding characteristics (strategy, intended outcome, fading schedule, scaffolding intervention, and paired intervention) influence cognitive student outcomes. It includes detailed descriptions of the theoretical foundations of scaffolding, scaffolding strategies that have been proposed to meet different intended learning outcomes in STEM, and associated efficacy information. Furthermore, the book describes assessment strategies and study designs which can be used to evaluate the influence of scaffolding, and suggests new fields in which scaffolding strategies that have proven efficacious may be used

    Model and Mathematics: From the 19th to the 21st Century
    ( 2022)
    Michael Friedman, Karin Krauthausen (editors)
    This open access book collects the historical and medial perspectives of a systematic and epistemological analysis of the complicated, multifaceted relationship between model and mathematics, ranging from, for example, the physical mathematical models of the 19th century to the simulation and digital modelling of the 21st century. The aim of this anthology is to showcase the status of the mathematical model between abstraction and realization, presentation and representation, what is modeled and what models.

    The Models of Engaged Learning and Teaching
    ( 2020)
    John Willison
    This book provides a practical philosophy for promoting students' sophisticated thinking from Early Childhood to PhD in ways that explicitly interconnect across the years of education. It will help teachers, academics and the broader learning and teaching community to understand and implement these connections by introducing a conceptual framework, the Models of Engaged Learning and Teaching (MELT). By covering the nature, philosophy, practice and implications of MELT for teachers and students alike, the book will help teachers to facilitate students’ awareness of, and increasing responsibility for, the thinking demanded by subject and discipline-specific learning as well as interdisciplinary learning, whether face to face, online or in blended modes. The book will also provide educators with ways to effectively engage with complex, and sometimes conflicting, contemporary educational concepts, and with a diverse variety of colleagues involved in the learning and teaching enterprise. The book provides guidance that allows curriculum improvement, teacher action research and larger-scale research to be reported on from a common perspective, bridging the gap between those readers focused on research and those focused on teaching. The book shares valuable insights and ways of addressing the contemporary issue of discipline-based learning versus transdisciplinary learning, reducing the dichotomy and enabling the two approaches to complement each other.

    Transmedial Narration
    ( 2019)
    Lars Elleström
    This open access book is a methodical treatise on narration in different types of media. A theoretical rather than a historical study, Transmedial Narration is relevant for an understanding of narration in all times, including our own. By reconstructing the theoretical framework of transmedial narration, this book enables the inclusion of all kinds of communicative media forms on their own terms.The treatise is divided into three parts. Part I presents established and newly developed concepts that are vital for formulating a nuanced theoretical model of transmedial narration. Part II investigates the specific transmedial media characteristics that are most central for realizing narratives in a plenitude of different media types. Finally, Part III contains brief studies in which the narrative potentials of painting, instrumental music, mathematical equations, and guided tours are illuminated with the aid of the theoretical framework developed throughout the book. Suitable for advanced students and scholars, this book provides tools to disentangle the narrative potential of any form of communication.

    Triple-layer remote phosphor structure: a selection of the higher color quality and lumen efficiency for WLEDs

    To enhance color quality of glass-based phosphor-converted white light-emitting diodes (pc-WLEDs) with multi-layer remote phosphor layer structures, two phosphors, green CdS:In and red ZnS:Te,Mn, are integrated into the glass matrix and applied to the dual-layer and triple-layer WLED packages. The attained results were examined with Mie-scattering theory and Lambert-Beer law. The dual-layer showed significant enhancement in color rendering index (CRI), in the range of approximate 80-90. Meanwhile, CRI in the triple-layer was lower and stayed around 66. In terms of color quality scale (CQS), a more overall color evaluating index, triple-layer structure helps the glass-based WLED achieve higher value than the dual-layer. The triple-layer is also beneficial to the luminous efficacy, according to the experimented results. Thus, the triple-layer structure can be used to strengthen the benefit of the glass matrix used in WLED products.
