Factors Affecting Stock Prices with EPS as Moderating Variable Among Manufacturing Companies
Authors: Nathania Madeline , Wijaya Henryanto
Published: August 2023

The goal of this study is to look at the impact of liquidity, profitability, and also solvency towards the stock prices in manufacturing businesses issued on the Indonesia Stock Exchange (IDX) starting from 2018 to 2020, utilizing Earnings per Share (EPS) as a moderating variable. In order to gain samples for the research, we used descriptive quantitative with purposive sampling technique. The data collected contains 210 samples, including 70 manufacturing enterprises that were listed on the IDX from 2018 to 2020. Moderated Regression Analysis (MRA) is used in conjunction with EViews 10 software to process the data. MRA is used to model the case because in MRA, the regression equation contains interaction element between variables to know if the effect of a moderating variable is getting stronger or weaker. The findings reveal that both liquidity and profitability brings a advantageous and large impact towards stock prices, whereas solvency and EPS have a negative and minor impact, and that EPS can mitigate the impact of profitability, liquidity, and solvency in relation to stock prices. This study's implications include the need to enhance a company's performance and financial situation so that its financial statements are sound and stock prices rise, which is, of course, a good sign for investors.

Authors: Lampropoulos Georgios
Published: August 2023

This study aims to examine K-12 teachers’ perspectives and attitudes toward the benefits of adopting and integrating digital game-based learning in education. The study involves 158 teachers of primary education and secondary education who filled in a 37-question questionnaire. Overall, teachers had significantly positive perspectives and attitudes. In contrast to their age and level of education in which they taught, teachers’ educational background, gender, and teaching experience were correlated with their responses. Based on the results, most teachers were familiar with digital games and their use in educational settings and had previous experience in adopting digital game-based learning in their classrooms. The lack of equipment, digital skills, and training emerged as the primary challenges that they face. Concerning its general benefits in education, digital game-based learning emerged as an effective educational approach that can be applied in various subjects and offer interactive and student-centered learning environments. Regarding the benefits it can yield for teachers, digital game-based learning emerged as a useful educational approach that can facilitate and enrich the teaching process as it improves teachers’ communication and digital skills and enables them to create motivational virtual learning environments that would consciously engage and encourage students to actively participate in educational activities and that would promote collaborative learning. In terms of the educational benefits that it can yield for students, digital game-based learning was evaluated as a valuable pedagogical approach that can enhance students’ cognitive and social-emotional development, enhance their digital competencies, improve their learning motivation, engagement, and achievements, and increase their joy, autonomy, critical thinking, creativity, and imagination. Finally, digital game-based learning emerged as an effective educational approach that can be used at all educational levels and in both face-to-face and online learning to meet the new educational requirements, provide benefits for teachers and students, and improve the overall quality of education.

Authors: Mulya Dimmas
Published: August 2023

In this digital era, character recognition technology and letter classification are topics that are increasingly attracting attention, especially in the context of developing applications for learning Arabic, text processing, and artificial intelligence systems. There have been many previous studies examining this topic. However, there are still many opportunities to develop models for classifying hijaiyah letters to help many people learn to write hijaiyah letters.
In this study, building a hijaiyah letter classification model using Hybrid-CNN and CatBoost, where CNN is used as a feature extractor and CatBoost as a classifier. CNN will be trained first to become a feature extractor and the results of the CNN model will be used as a feature extractor to create feature representation for training and testing CatBoost model. The AHDC dataset was used in this study and succeeded in achieving an accuracy value of 96.07%. Although it has not been able to compete with previous research, the Hybrid-CNN model with CatBoost has good potential in the future.
Framing Science in the Media: Case Study of News on Bolshaya Udina Volcano
Authors: Pozdnyakova Ju. S.
Published: August 2023

The article considers the process of transformation of framing of science from a researcher (6 letters, 5 versions of the text with corrections) through the news in corporate mass media (press release, 1 text) to other mass media (8 texts in English, 1 text in German, 59 texts in Russian). Three frames were identified in the original text: “narrative of the progress of the study”, “catastrophizing the results of the study”, and “the need for additional observations for more accurate research results”. The media exploited the “catastrophizing” frame most actively: 6 texts in English, 1 text in German, 42 texts in Russian. Also, journalists implemented one more frame – “verification of results by external experts” (1 time in English and 1 time in Russian). In the texts in Russian has appeared another source of information –  a press-release by the Institute of Volcanology and Seismology, which can be singled out in a separate frame “refutation of the results obtained by external experts” (15 texts). There has been a convergence of the format of news and a press release about scientific results since journalists used texts prepared by press services without verification and external comments. As a result, the frames of the original text are duplicated in mass media. If the frame is based on sensation, the emphasis on sensation increases in further replication when information about the research (its methodology, problems, and development) decreases.

Published: August 2023

Objetivo: Realizar um levantamento bibliográfico sobre os aspectos primordiais, vantagens e limitações das lentes de contato dental. Revisão bibliográfica: As lentes de contato dental são uma opção estética para melhorar o sorriso de forma rápida e com pouco desgaste dentário. Dentre as vantagens estão a alta durabilidade, a preservação da estrutura dental remanescente, a facilidade de aplicação e o resultado estético satisfatório. Com essas lentes, é possível corrigir problemas como dentes desalinhados, manchas, lascas e espaçamento entre os dentes. Porém, há algumas desvantagens, como a impossibilidade de alterar a cor dos dentes em mais de dois tons, a limitação em casos de grande modificação do posicionamento dentário, a necessidade de manter uma boa higiene bucal e a contraindicação em casos de esmalte dentário superficial insuficiente, sobrecarga oclusal, bruxismo, doença periodontal e grandes destruições coronárias. Considerações finais: As lentes de contato dentais são uma opção estética moderna e menos invasiva para melhorar o sorriso. Com avanços técnicos e materiais, oferecem resultados estéticos e naturais, desde que indicadas corretamente e com cuidados adequados. O dentista deve realizar uma avaliação individualizada para determinar se são a melhor opção para cada paciente em busca do sorriso perfeito.

Regioselective glycosylation of polyphenols by family 1 glycosyltransferases: experiments and simulations
Authors: de Boer Ruben Marcel , Vaitkus Dovydas , Enemark-Rasmussen Kasper , Maschmann Sören , Teze David , Hededam Welner Ditte
Published: August 2023

Family 1 glycosyltransferases (GT1s, UGTs) form natural product glycosides with exquisite control over regio- and stereoselectivity, representing attractive biotechnological targets. However, regioselectivity cannot be predicted and large-scale activity assessment efforts of UGTs are commonly performed via mass spectrometry or indirect assays that are blind to regioselectivity. Here, we present a large HPLC screening discriminating between regioisomeric products of 40 diverse UGTs (28.6% average pairwise sequence identity) against 32 polyphenols, identifying enzymes able to reach high glycosylation yields (≥90% in 24h) in 26/32 cases. In reactions with >50% yield, we observed perfect regioselectivity for 47% (75/158) on polyphenols presenting two hydroxyl groups, and for 30% (43/143) on polyphenols presenting ≥3 hydroxyl groups. Moreover, we developed an NMR-based procedure to identify the site of glycosylation directly on enzymatic mixtures. We further selected seven regiospecific reactions catalyzed by four enzymes on five dihydroxycoumarins. We characterized the four enzymes, showing that temperature optima are functions of the acceptor substrate, varying by up to 20°C for the same enzyme. Furthermore, we performed short molecular dynamics simulations of 311 ternary complexes (UGT, UDP-Glc, glycosyl acceptor) to investigate the molecular basis for regioselectivity. Interestingly, it appeared that most UGTs can accommodate acceptors in configurations favorable to the glycosylation of either hydroxyl. In contrast, evaluation of hydroxyl nucleophilicity appeared a strong predictor of the hydroxyl predominantly glycosylated by most enzymes.
Dual Ratiometric Fluorescence Monitoring of Mechanical Polymer Chain Stretching and Subsequent Strain-Induced Crystallization
Authors: Suga Kensuke , Yamakado Takuya , Saito Shohei
Published: August 2023

Tracking the behavior of mechanochromic molecules provides valuable insights into force transmission and associated microstructural changes in soft materials under load. Herein, we report a dual ratiometric fluorescence (FL) analysis for monitoring both mechanical polymer chain stretching and strain-induced crystallization (SIC) of polymers. SIC has recently attracted renewed attention as an effective mechanism for improving the mechanical properties of polymers. A polyurethane (PU) film incorporating a trace of a dual-emissive flapping force probe (N-FLAP, 0.008 wt%) exhibited a blue-to-green FL spectral change in a low stress region (< 20 MPa), resulting from conformational planarization of the probe in mechanically stretched polymer chains. Only at higher probe concentrations (~0.65 wt%), the PU film showed a second spectral change from green to yellow during the SIC growth (20–65 MPa) due to self-absorption of scattered FL in a short wavelength region. The reversibility of these spectral changes was demonstrated by load-unload cycles. With these results in hand, the degrees of the polymer chain stretching and SIC were quantitatively mapped and monitored by dual ratiometric imaging based on different FL ratios (I525/I470 and I525/I600). Simultaneous analysis of these two mappings revealed a spatio-temporal gap in the distribution of the polymer chain stretching and the SIC. The combinational use of the dual-emissive force probe and the ratiometric FL imaging is a universal approach for the development of soft matter physics.
Rapid and simple 13C-hyperpolarization by 1H dissolution dynamic nuclear polarization followed by an in-line magnetic field inversion

Published: August 2023

Dissolution dynamic nuclear polarization (dDNP) is a method of choice for preparing hyperpolarized 13C metabolites such as [1-13C]-pyruvate used for in vivo applications including the real-time monitoring of cancer cell metabolism in human patients. The approach consists of transferring the high polarization of electron spins to nuclear spins via microwave irradiation at low temperatures (1.0-1.5 K) and moderate magnetic fields (3.3-7 T). The solid sample is then dissolved and transferred to an NMR spectrometer or MRI scanner for detection in the liquid state. Common dDNP protocols use direct hyperpolarization of13C spins reaching polarizations of >50% in ~1-2 hours. Alternatively, 1H spins are polarized before transferring their polarization to 13C spins using cross-polarization (CP), reaching similar polarization levels as direct DNP in only ~20 min. However, it relies on more complex instrumentation, requiring highly skilled personnel. Here, we explore an alternative route using 1H dDNP followed by an inline adiabatic magnetic field inversion in the liquid state during the transfer. 1H polarizations of >70% in the solid-state are obtained in ~5-10 min. As the hyperpolarized sample travels from the dDNP polarizer to the NMR spectrometer, it goes through a field inversion chamber, which causes 1H→13C polarization transfer. This transfer is made possible by the J-coupling between the heteronuclei, which mixes the Zeeman states at zero-field and causes an anti-level crossing. We report liquid-state 13C polarization up to ~17% for [3-13C]-pyruvate and 13C-formate. The instrumentation needed to perform this experiment in addition to a conventional dDNP polarizer is simple and readily assembled.
5-Nitrofuranyl Derivatives are Reactive Towards Methanolic Media as Exemplified by 1H, 13C NMR Spectroscopy & Their Colours
Authors: Dey Ashley L.
Published: August 2023

Most 5-nitrofuranyl derivatives, in particular, the frequently used 5-nitrofurfural building block in synthesis, are coloured compounds and their intrinsic colours can be a good indication of their purity by virtue of their specific extended π-delocalisation. To this end, the work herein reports a first-of-its-kind anhydrous synthesis of (E)-5- nitrofuran-2-yl methylene hydrazine, 5-nitrofuran-2-carbohydrazide, and its dimeric 5-nitro-N'-5-nitrofuran-2- carbonyl furan-2-carbohydrazide, alongside their intrinsic colours, and most importantly their reactivity towards several deuterated solvents together with their 1H and 13C NMR features in an attempt to unravel the basis of discrepancies in the appearance of purported (E)-5-nitrofuran-2-yl methylene hydrazine of high purity in the literature and that obtained herein.

Lithium-sulfur batteries are considered as promising candidates for next-generation energy storage devices for grid applications due to their high theoretical energy density. However, the inevitable shuttle effect of lithium polysulfides and/or dendrite growth of Li metal anodes hinder their commercial viability. Here, the microporous Zr fumarate MOF-801(Zr) was considered to produce thin (~15.6 µm, ~1mg cm2) mixed matrix membranes (MMM) as a novel interlayer for Li-S batteries. It was found that the MOF-801(Zr)/C/PVDF-HFP composite interlayer facilitates Li+ ions diffusion, and anchors polysulfides while promoting their redox conversion effectively. We demonstrated that MOF-801 effectively trapped polysulfides at the cathode side, and confirmed for the first time the nature of the interaction between the adsorbed polysulfides and the host framework, through a combination of solid-state NMR and molecular dynamics simulations. The incorporation of MOF-801(Zr)/C/PVDF-HFP MMM interlayer resulted in a notable enhancement in the initial capacity of Li-S batteries up to 1110 mA h g-1. Moreover, even after 50 cycles, a specific capacity of 880 mA h g-1 was delivered.

Gas-liquid Interface plays key roles in many fantastic phenomena due to specific properties. Although remarkable reactivities were benefited from gas-water interface of aqueous microdroplets, it remains unknown for gas-organic interface. This work discovers such extraordinary reactivity of gas-organic interface using organic microdroplets (acetonitrile and other organic solvents). This reactivity at the gas-organic interface facilitated a novel micrordroplet-controlled divergence, i.e., double C–N cleavage in high efficiency (yields > 90% in milliseconds) compared to single C–N bond breakdown and intramolecular cycloarrangement in bulk under harsher conditions from the same imidazolines. This study is not only important to wide applicability and inherent mechanisms of the gas-organic interface but also enables good insights into gas-water and other interface-rich studies in atmospheric and photochemistry, on-water chemistry, biological and biomedical, industrial, and energy.

El presente trabajo de investigación ha planteado el objetivo de analizar la responsabilidad social empresarial: artículos de revisión de la literatura. La metodología fue no experimental, en donde se ha considerado el empleo de la guía de análisis documental para valorar un total de 50 artículos de investigación científica. Los resultados han demostrado que, la responsabilidad social empresarial se puede abarcar como el compromiso que llega a tener una entidad en referencia con acciones sociales, con la finalidad de responsabilizarse de la comunidad, en consecuencia, de la repercusión que puede tener su actividad económica, beneficiando con ello a un mayor índice de aceptación, una mayor sostenibilidad en el tiempo y un mejor posicionamiento e identidad de marca. Además, se ha concluido que, esta llega a ser fundamental para las organizaciones, debido a que existió evidencia en donde las entidades que la practican de manera sostenida llegan a aumentar su valor, no solo desde la percepción por parte de los usuarios, sino desde el conjunto de acciones corporativas que le permiten posicionarse dentro de un mercado

El objetivo de este estudio radica en proponer políticas de inversión privada que contribuyan a optimizar el desarrollo económico de los pobladores de la región Lambayeque. Se identificaron problemas relacionados con las brechas en el progreso económico, por razones que faltan de políticas sólidas que incentiven a los inversores privados. En el desarrollo del estudio, se ha utilizado la metodología cuantitativa de tipo no experimental y diseño transversal, con una muestra no probabilística que incluyó el análisis de documentos del período comprendido entre 2016 y 2020. Los resultados indican que el desarrollo económico en la región no fue suficientemente óptimo para los ciudadanos. En cuanto al crecimiento económico, se ha evidenciado que el producto bruto interno ha experimentado aumentos constantes durante esos años, excepto en el año 2020 cuando se redujo. En términos socioeconómicos, se confirmó aumentos en la población económicamente activa desempleada, analfabetismo, pobreza y el déficit de hogares con servicios básicos en el año 2020. En vista de estos hallazgos, se propone una política de inversión privada que busque mejorar la gestión y regulación del gobierno regional y local en materia de inversiones, con el objeto de optimizar el desarrollo económico de la región.

Authors: Cobos Gutiérrez Carlos Eduardo , Izquierdo Espinoza Julio Roberto
Published: August 2023

El estudio realizado en 2022 buscó determinar la relación entre la infraestructura de ciclovías y el desarrollo sostenible en la urbanización retablo del distrito de Comas. Se empleó una metodología cuantitativa, de diseño no experimental y correlacional. La muestra consistió en 69 ciclistas de dicha urbanización, quienes contestaron cuestionarios con preguntas cerradas basadas en una escala ordinal. Los resultados revelaron lo siguiente: La infraestructura urbana, como las ciclovías en la urbanización Retablo, no solo influye en la movilidad y estética de la ciudad, sino que también juega un papel crucial en determinar la sostenibilidad de la región. La planificación adecuada puede ser una herramienta esencial para contrarrestar los impactos negativos del desarrollo urbano. Aunque la seguridad de las ciclovías no muestra una fuerte correlación directa con el desarrollo sostenible, sigue siendo un factor crucial en la planificación urbana. Un diseño adecuado puede mejorar la calidad de vida y garantizar un desplazamiento seguro para ciclistas y peatones. La falta de una relación directa entre la seguridad de las ciclovías y el desarrollo sostenible puede indicar la necesidad de campañas de sensibilización. Las rutas directas minimizan el tiempo de viaje y ofrecen a los ciclistas una experiencia más predecible y eficiente. La propuesta de Milla no solo se basa en especificaciones técnicas, sino también en cómo se integra con otros aspectos del entorno, como la vegetación. La falta de relación entre la dimensión "cómodas" y el desarrollo sostenible sugiere que simplemente tener una ciclovía no es suficiente.
