Análise da miocardite como desfecho da vacinação para COVID-19
Authors: Santos Daniel Miranda , Marotta Camila dos Santos , Lima Ramon Fraga de Souza
Published: January 2024

Objetivo: Entender melhor as características e resultados da miocardite relacionada à vacina da COVID-19. Revisão bibliográfica: Eventos raros, como pericardite e miocardite, foram relatados em pacientes que receberam vacinas de mRNA de empresas como Pfizer e Moderna. Esses eventos geralmente ocorrem nos primeiros 14 dias de vacinação e são mais comuns após a segunda dose e em homens com idade entre 12 e 30 anos. Os principais sintomas são dor no peito, falta de ar ou palpitações. É necessário confirmar o diagnóstico com exames complementares, que são realizados em uma emergência hospitalar. Essa avaliação inclui eletrocardiograma, dosagem de marcadores de necrose cardíaca (troponina e CK-MB) e exames de imagem (ecocardiograma, tomografia computadorizada ou ressonância magnética) incluídos na avaliação. O tratamento é de suporte e sintomático para o controle da dor. Os riscos conhecidos do COVID-19 e suas complicações potencialmente graves, como condições pós-COVID-19, hospitalização e morte, superam em muito os riscos potenciais de uma reação adversa rara à vacinação, incluindo o risco potencial de miocardite ou pericardite. Considerações finais: A análise risco-benefício das vacinas mRNA COVID-19 traz resultados positivos em favor da vacinação, já que o número de casos prevenidos é exponencialmente maior que o número de eventos adversos relatados.

Published: January 2024

Objetivo: Analisar o padrão de mecanismos de lesão do LCA, para assim determinar as melhores formas de prevenção, além de estabelecer as terapêuticas mais eficazes na reabilitação à prática esportiva. Métodos: A abordagem metodológica desse trabalho se propõe a um compilado de pesquisa bibliográfica de abordagem qualitativa e caráter descritivo por meio de uma revisão integrativa da literatura nas bases de dados National Library of Medicine e Biblioteca Virtual em Saúde. Os descritores utilizados foram “ligament”, “soccer” e “rehabilitation”. Os critérios de inclusão foram estudos observacionais e ensaios clínicos controlados, publicados em inglês, no intervalo de 2017 a 2022. Resultados: É impossível impedir a lesão de LCA de acontecer, já que os atletas sempre estarão sujeitos ao contato físico, salto e mudança de direção, porém existem formas de tornar a musculatura mais resistente aos impactos para que a força necessária para a lesão seja maior, tornando-a assim menos incidente. As complicações pós cirúrgicas podem ser evitadas, e quando não forem, existem maneiras viabilizar o retorno a pratica esportiva e o alivio de dores do paciente. Considerações finais: A lesão de LCA pode ter sua incidência reduzida, o seu tratamento é geralmente cirúrgico e o acompanhamento pós cirúrgico requer dedicação.

Published: January 2024

The paper offers a thorough analysis of immunotherapeutics with a focus on hybridomas. It describes how focused and precise treatments for a variety of illnesses, such as cancer, autoimmune disorders, and infectious diseases, have been made possible by immunotherapeutics, which are based on antibody and hybridoma technology. The main therapeutics produced by this method are monoclonal antibodies (mAbs). The article describes the hybridoma technology process, in which a heterogeneous population of cells that produce unique mAbs are created by combining immortalized myeloma cells with B lymphocytes. To isolate and create drug formulations, the hybridoma cells that produce the desired antibodies are chosen and grown in large numbers. In the article, successful uses of immunotherapeutics based on antibody and hybridoma technology are highlighted. Hybridoma technology used in treatment of autoimmune conditions, viral infections and cancer. The potential of mAbs to increase the range of available treatments is also covered. The page also describes the distinction between monoclonal and polyclonal antibodies, how they are made, and the different uses of hybridoma technology in research, diagnostics, therapy, vaccine development, and fundamental immunology investigations. The importance of immunotherapeutics based on antibody and hybridoma technologies in revolutionizing the treatment environment and creating new opportunities for customized and targeted therapies is emphasized as it draws to a close.

Purpose. A clinical case demonstrating surgical reconstruction of the pupil for bilateral Peters anomaly. Material and methods. Patient F., 20 years old. Complaints of vision problems in the left eye. Left eye: microcornea (up to 7–8 mm), the anterior chamber is small, uneven, multiple iridocorneal adhesions at 2.5 and 7 o’clock. The pupil is narrow – 1.0 mm, round, ectopic 2.2 mm upward from the optical center of the cornea, posterior stromal circular synechia, no pupillary reaction to light and mydriatics. Results. A tunnel corneoscleral incision with a width of 2.0 mm was formed at 9 o’clock, as well as 2 paracenteses: at 2 and 6 o’clock. Through the local zone of absence of posterior synechiae and residual native pupillary opening (1.0 mm), a 0.6 mm spatula was placed under the plane of the iris, and a posterior synechiotomy was performed. Then, using 25G scissors, the existing pupillary opening was expanded to 4.2 mm in the area of its planned localization. At the end of the operation, the viscoelastic was washed out of the anterior chamber and standard sealing of surgical approaches was performed. The next day the patient noted an improvement in the brightness of the visual image perceived by the eye, and the visual field expanded. Conclusion. The presented clinical case demonstrated the possibilities of surgical dilation of the pupil when it tends to be completely closed in an eye with congenital Peters anomaly.

DETERMINATION OF THE SPECIFIC INTERPHASE SURFACE OF BUBBLES BASED ON IMAGES (ON THE EXAMPLE OF THE AERATION PROCESS USING ULTRASONIC)
Authors: Голых Р.Н. , Барсуков А.Р.
Published: January 2024

Исследован процесс увеличения межфазной поверхности при использовании ультразвуковых колебаний в режиме кавитации в условиях принудительной аэрации. Предложен алгоритм обработки изображений межфазной поверхности для определения её удельной площади. Разработанный метод обработки изображений обеспечивает точность определения удельной межфазной поверхности, связанную с растеризацией изображения, не превышающую 6%. Эта погрешность значительно меньше влияния ультразвуковых воздействий. В результате анализа изображений установлено, что ультразвук способствует увеличению межфазной поверхности более чем в 3 раза.

The process of increasing the interfacial surface using ultrasonic vibrations in the cavitation mode under conditions of forced aeration has been studied. An algorithm is proposed for processing images of the interfacial surface to determine its specific area. The developed image processing method provides an accuracy in determining the specific interphase surface associated with image rasterization that does not exceed 6%. This error is significantly less than the influence of ultrasonic influences. As a result of image analysis, it was found that ultrasound helps to increase the interfacial surface by more than 3 times.

Published: January 2024

Рассмотрено расчётно-теоретическим способом влияние 1,9-диазидо-2,4,6,8-тетранитро-2,4,6,8-тетраазанонан (ДИАЗ-4) и 2,4-динитротолуола (ДНТ) на адиабатическую температуру горения и силу пороха полимерносвязанных метательных композиций. Основой для горючих-связующих (ГСВ) используются высокомолекулярные соединения полиглицидилнитрат (p-GLYN) и полиглицидилазид (GAP). Наполнители: 3-нитро-1,2,4-триазол-5-он (NTO), 1,3,5-триамино-2,4,6-тринитробензол (TATB), 1,1-диамино-2,2-динитроэтен (Апрол, FOX-7), динитрамид N-гуанилмочевины (FOX-12), 1,3,3-тринитроазетидин (TNAZ). Показано, что ДНТ является эффективным материалом для снижения температуры (до 55,1 %) в смесях с высоким кислородным балансом; ДИАЗ-4 является модификатором, способным к одновременному увеличению адиабатической температуры горения смесей и силы пороха в широком диапазоне. Это обеспечивает возможность прогнозирования термодинамических характеристик композиций на основе МЧВВ в областях целевого применения.

The influence of 1,9-diazido-2,4,6,8-tetranitro-2,4,6,8-tetraazanonane (DIAZ-4) and 2,4-dinitrotoluene (DNT) on the adiabatic temperature and the powder force of polymer-bound propellant compositions is considered by a computational and theoretical method. Polymers polyglycidylnitrate (p-GLYN) and polyglycidylazide (GAP) are used as binders. Fillers: 3-nitro−1,2,4-triazole-5-one (NTO), 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), 1,1-diamino-2,2-dinitroethene (Aprol, FOX-7), N-guanylurea dinitramide (FOX-12), 1,3,3-trinitroazetidine (TNAZ). It has been shown that DNT is an effective material for reducing temperature (up to 55.1%) in mixtures with a high oxygen balance; DIAZ-4 is a modifier capable of simultaneously increasing the adiabatic combustion temperature of mixtures and the powder force over a wide range. This makes it possible to predict the thermodynamic characteristics of compositions based on MPV in areas of target application.

Нитраты спиртов-теломеров представляют интерес в качестве пластификаторов для полимеров, в том числе и для фторопласта Ф-42Л, который является как легко, так и труднорастворимым растворителем при создании высокоэнергетических композиций. В статье рассмотрен синтез нитратов спиртов-теломеров реакцией нитрования серно-азотной нитрующей смесью. Структура нитратов спиртов-теломеров подтверждена методами ИК- и ЯМР-спектроскопии. Исследованиями методом DTA (DSC, TGA) показано, что нитраты спиртов-теломеров являются устойчивыми летучими соединениями при нагревании, образовывают пластификаты с фторопластом Ф-42Л. В результате разработан метод получения 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9-гексадекафторнонил нитрата с выходом 81,58 % и 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11-эйкозафторундецил нитрата с выходом 89,29 %.

Nitrates of telomere alcohols are of interest as plasticizers for polymers, including for fluoroplast F-42L as an easily or difficult-to-dissolve solvent when creating high-energy compositions. The article considers the synthesis of nitrates of alcohols-telomeres by the nitration reaction with a sulfur-nitrogen nitrating mixture. The structure of nitrate alcohols-telomeres was confirmed by IR and NMR spectroscopy. Studies using the DTA (DSC, TGA) method have shown that nitrates of telomere alcohols are stable volatile compounds when heated, form plasticizers with fluoroplast F-42L. As a result, a method was developed for obtaining 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9-hexadecafluoronyl nitrate with a yield of 81.58% and 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11- eicosafluoroendecyl nitrate with a yield of 89.29%.

Authors: Sholikhi Fu'ad , Zuliansadewi Sikha
Published: January 2024

The transition from traditional classroom-based language learning to online learning outside the classroom particularly in response to the global Covid-19 pandemic has transformed the way educators and learners approach teaching and learning activities. This research provides insights into the views of twelve Public Administration students on the use of YouTube videos for learning English digitally outside the classroom in their speaking class. The investigators utilized a qualitative research approach, conducting thorough in-depth interviews and observations. The initial step in analyzing the data of Public Administration students’ perception was data reduction, which was subsequently followed by additional data reduction and the drawing of conclusions. The results revealed that many of the participants concurred that YouTube had a substantial impact on their speaking class. Despite a small number of students encountering network-related issues, such as quota limitations or Fair Usage Policy (FUP) and advertisements, the study also demonstrated that this web application provided a free supplementary learning course for the speaking class.
NaCl, MgCl2, and AlCl3 Surface Coverages on Fused Silica and Adsorption Free Energies at pH 4 From Nonlinear Optics
Authors: Olson Alyssa , Alghamdi Amani , Geiger Franz
Published: January 2024

We employ amplitude- and phase-resolved SHG experiments to probe interactions of fused silica:aqueous interfaces with Al3+, Mg2+, and Na+ cations at pH 4 and as a function of metal cation concentration. We quantify the second-order nonlinear susceptibility and the total potential in the presence and absence of 10 mM screening electrolyte to understand the influence of charge screening on cation adsorption. Strong cation:surface interactions are observed in the absence of screen electrolyte. The total potential is then employed to estimate the total number of absorbed cations. The contributions to the total potential from the bound and mobile charge were separated using Gouy-Chapman-Stern model estimates. All three cations bind fully reversibly, indicating physisorption as the mode of interaction. Of the isotherm models tested, the Kd adsorption model fits the data with binding constants of 3 to 30 mol-1 and ~300 mol-1 for the low (<0.1 mM) and high (0.1 -3 mM) concentration regimes, corresponding to adsorption free energies of -13 to -18 and -24 kJ mol-1 at room temperature, respectively. The maximum surface coverages are around 1013 cations cm-2, matching the number of deprotonated silanol groups on silica at pH 4. Clear signs of decoupled Stern and diffuse layer nonlinear optical responses are observed and found to be cation specific.
Phosphosulfide semiconductors for optoelectronics and solar energy conversion
Authors: Mittmann Lena Angelika , Crovetto Andrea
Published: January 2024

Inorganic phosphosulfides – materials containing phosphorus, sulfur, and at least one metal – are a vast and chemically-versatile family of materials. Benefiting from a wide range of possible phosphorus oxidation states, phosphosulfide semiconductors exist as thiophosphate compounds with various types of P-S polyanions, as genuine multi-anion compounds with or without P-P bonds, as solid solutions, and as many intermediate cases. Since metal phosphides and metal sulfides are among the highest-performing optoelectronic semiconductors, it seems reasonable to consider the phosphosulfide family as a potential pool of materials for solar cells, photoelectrochemical cells, and light-emitting diodes. Nevertheless, phosphosulfide semiconductors have very rarely been characterized with these applications in mind. In this Perspective, we reflect on the potential applicability of known and hypothetical phosphosulfides as light absorbers and emitters in optoelectronic devices. First, we distill the existing knowledge accessible through the Materials Project database, finding promising phosphosulfides among the compounds already present in the database, and identifying what we see as the general advantages and challenges of phosphosulfides as optoelectronic materials. Then, we propose three concrete research directions aimed at finding novel high-quality phosphosulfide semiconductors with high light absorption coefficients, high carrier mobilities, and long carrier lifetimes. In particular, we argue that the versatility of phosphorus in this class of materials could potentially be exploited to engineer defect tolerance. Finally, we devise and describe a custom synthesis setup dedicated to high-throughput exploration of thin-film phosphosulfides.

Enquadramento e processos de midiatização na construção e interpretação de realidades dos brasileiros no exterior
Authors: Escudero Camila
Published: January 2024

O objetivo deste trabalho é compreender como as notícias sobre emigrantes brasileiros são elaboradas a partir de um enquadramento mediatizado capaz de atribuir a uma situação e seus envolvidos características e valores, criando elementos para interpretação de uma realidade. Assim, realizamos uma análise de conteúdo – de abordagem quantitativa e qualitativa com categorias baseadas na perspectiva de enquadramento noticioso, temático e episódico e no conceito de mediatização –, de matérias e reportagens sobre brasileiros que vivem no exterior publicadas nos portais G1 e UOL, de maio de 2021 a maio de 2022. O estudo evidenciou fragilidades e potencialidades dos processos migratórios, não, necessariamente, de maneira equilibrada e explícita. Isso significa dizer que, por meio das notícias construídas a partir de processos de apropriação e recorte dos fatos, bem como de lógicas relacionadas à midiatização, expõe-se a temática constituindo um campo simbólico de conhecimento que colabora para a construção de estruturas cognitivas e interpretativas sobre a realidade envolvida.
Las Poderosas Teatro.
Authors: Martínez Alvarez Martha Olimpia
Published: January 2024

La violencia de género en Guatemala ha dejado heridas que requieren estrategias colectivas para su sanación. Este artículo aborda la percepción de las mujeres del grupo Las Poderosas Teatro respecto al papel de esta expresión artística en la construcción de rutas para la sanación de las experiencias de diferentes tipos y modalidades de la violencia que han vivido. Desde el enfoque fenomenológico de la investigación cualitativa, con base en entrevistas de relatos de vida, identifica las estrategias colectivas que han descubierto Las Poderosas a lo largo de su trayectoria, y que han movilizado sus identidades para resignificar lo vivido para sí mismas y para las demás. El teatro como herramienta comunicativa y de sanación permitió a Las Poderosas pasar de asumirse víctimas de violencias vividas en lo individual, a reconocerse sobrevivientes de violencias estructurales, y finalmente a ser defensoras de derechos de mujeres, colectivos y comunidades atravesados por diversas manifestaciones de la violencia.

El aprendizaje dialógico, proceso para el fortalecimiento de las habilidades comunicativas
Authors: Pérez Yadi Milena
Published: January 2024

La calidad educativa es un tema que en los últimos años ha generado una gran preocupación, derivada por el bajo rendimiento académico que se evidencia tanto en las prácticas de aula como en los resultados de las pruebas externas. Por esto, se hace necesario determinar los posibles factores que inciden en dicha problemática, encontrando que la falta de apropiación y uso significativo de las habilidades comunicativas son elementos que influyen en los procesos de aprendizaje y por ende, en los resultados académicos. Por tal razón, surge la idea de una investigación de tipo cualitativa, encaminada a fortalecer las habilidades comunicativas de los estudiantes de tercer grado, a través del aprendizaje dialógico. Las técnicas de recolección de datos utilizadas fueron: la entrevista semiestructurada, el cuestionario y la bitácora; estas permitieron analizar los resultados, los cuales arrojan una mejora significativa en los procesos comunicativos que influyen directamente en el aprendizaje, como lo son: la lectura, la escritura, la escucha activa y la expresión oral.
Se concluye que las estrategias basadas en el diálogo como, por ejemplo, las tertulias dialógicas, fortalecen los procesos comunicativos de los estudiantes y les permite poder mejorar su desempeño académico y así sentar en el educando unas bases sólidas con las que pueda continuar fortificando su proceso de aprendizaje de una manera mucho más efectiva.

Autorregulación del aprendizaje: retos del aprendizaje activo
Authors: Abella Lizcano Lorena , Otondo Maite
Published: January 2024

El objetivo del presente artículo es evaluar la autorregulación del aprendizaje del estudiantado en un curso de Ciencia, Tecnología y Sociedad de la Universidad ICESI (Colombia). Es decir, se analiza el aprendizaje autónomo de los estudiantes y las estrategias metodológicas del docente. El texto es producto de un estudio de método mixto que incluyó las herramientas de encuesta y entrevista. Los resultados muestran que los estudiantes se esfuerzan por lograr los objetivos de aprendizaje y por comprender las lecturas asignadas, además que el docente diversifica las metodologías de enseñanza para estimular la participación de los estudiantes y su aprendizaje activo. Sin embargo, se percibe una débil autorregulación de los aprendizajes de los estudiantes que incide negativamente en sus habilidades cognitivas, compromiso y motivación; y consecuentemente en la significatividad de sus procesos de aprendizaje.
Effects of extraction temperature on bioactive compounds and antioxidant
activity of yellow velvetleaf (Limnocharis flava) and water lettuce (Pistia
stratiotes) leaf extract

Published: January 2024

Oxidative stress is considered a source of metabolic disorders. It is caused by an
imbalance between the body's antioxidant potential and free radical production. Therefore,
the body needs exogenous antioxidants, such as the bioactive compounds of plants. The
yellow velvetleaf (Limnocharis flava) and water lettuce (Pistia stratiotes) leaf showed
potential antioxidant activity because of their polyphenol compounds. This study aimed to
investigate the effects of extraction temperature on polyphenols and flavonoids as well as
their antioxidant activity on yellow velvetleaf and water lettuce leaf. The plant was
extracted by the maceration method in various processes using 70% ethanol. The results
showed the total polyphenol (TPC) and flavonoid content (TFC), as well as the
antioxidant content determined using the DPPH method. The highest TPC (512.5 mg
GAE/g of dried sample; 273.7 mg GAE/g of the dried sample) and TFC (209.5 mg QE/g
of dried sample; 641 mg QE/g of the dried sample) were observed in low-temperature
extraction. Under these conditions, the highest antioxidant activity (IC50) of yellow
velvetleaf and water lettuce was 0.207 mg/mL and 0.227 mg/mL, respectively. A low
extraction temperature is optimal for extracting these bioactive compounds, primarily
from yellow velvetleaf and water lettuce leaf.

Design/Methodology/Approach: This research was conducted in Blora Regency, Central Java, which is one of the regions in Indonesia that is rich in culture and local wisdom. Like other areas in Central Java, Blora has batik as a traditional craft which is quite popular. Until now, the Blora Regency Government continues to develop the sustainability of Blora batik through empowerment programs. The data analysis method used in this research is the Analytic Network Process (ANP) which is a mathematical theory that allows decision making to deal with interrelated factors (dependence) and mathematical feedback.
 
Findings: The findings in this study indicate that Batik Blora is a business unit that has the potential to develop and be competitive with various advantages. As a product that elevates regional advantages, it is necessary to increase business aspects that include upstream to downstream aspects so that the competitiveness of Blora batik can continue to increase.
 
Research, Practical & Social Implications: The most prioritized aspect in increasing the competitiveness of Blora batik is the aspect of the business cycle which emphasizes increasing innovation and diversification as well as increasing business productivity.
 
Originality/Value: This research is a research that focuses on the development strategy of Batik MSMEs with the ANP approach which has never been done before.

Purpose: The objective of this work is to apply a predictive model of bacterial growth to determine the concentration of total coliforms, under controlled laboratory conditions, in wastewater from the city of Riobamba that flows into the Chambo River (Ecuador).
 
Theoretical Framework: Wastewater pollution is a global problem that affects water quality and public health. Population growth has a drastic impact on the contamination of water bodies, particularly in Ecuador, since most of the effluents are not adequately treated, which becomes a public health and environmental problem. For this reason, over the years, total and fecal coliforms have been used as indicators of water quality.
 
Design/Methodology/Approach: The study used a mathematical modeling approach of a logistic and deterministic type, and calculated through an executable command designed in the integrated development environment (IDE) with the Visual C# programming language (logic) and the XAML design language (interface).
 
Findings: The results achieved are 1) the theoretical construction of a mathematical model (logistic model) starting from a differential equation and the taking of three experimental measurements, 2) the computer construction of the bacterial growth model and 3) it has been demonstrated that there is agreement between the values obtained from the model of total coliform growth and the experimental results with a margin of error of less than 1%.
 
Research, Practical & Social Implications: This information can be used by stakeholders to determine actions that could improve current conditions.
 
Originality/Value: The result of this study emphasizes that the model proposed can reproduce the growth of coliforms up to a maximum growth point, it is necessary to continue with the development of the same in the stationary phase of bacterial growth and then in the decay phase.

Published: January 2024

Purpose: The article aims to investigate how different understanding of ESG and/or CSR influence the adoption of formal ESG/CSR policy and relevant activities, and which factors are related to it as there is a gap in research
on the formation of ESG/CSR strategy.
 
Theoretical Framework: ESG strategies are one of the critical components for ensuring sustainable growth (Liang et al., 2022), but the understanding of the concept is not necessarily guaranteed. Moreover, despite the increasing interest in the topic, the literature concerning transition and emerging economies and ESG practices is still quite limited (Garcia et al., 2017).
 
Design/Methodology/Approach: We surveyed various national companies with scalability about their perception and implementation of CSR/ESG and identified three clusters of enterprises based on their understanding of responsibility and sustainability. We analyzed the likelihood of adopting a CSR/ESG strategy for each type.
 
Findings: The study reveals different elements which impact the process of forming a sustainability strategy in a transition economy and confirms the one of significant precondition is the company size. In addition, strong brands are seen as predictor of a strategy implementation.
 
Research, Practical & Social Implications: We suggest that business which tend to address the dimension of sustainability have a comprehensive attitude toward strategy adoption and for effectively practicing sustainability awareness of the concept and all its dimensions is key. Based on the classification of the different companies their CSR/ESG activities could be analyzed.
 
Originality/Value: The results show major factors of sustainability which are crucial to implement a formal sustainability strategy.
The Impact of Retailer Brand Name Substitution on Consumer Trust
Authors: Kannou Ahmed , Rached Kaouther Ben , Abdelkader Saoussen
Published: January 2024

Purpose: The aim of this article is to understand the impact of retailer brand name substitution on consumer trust.
 
Theoretical Framework: Drawing on existing research on product brand substitution, the paper introduces variables that could influence consumer trust in situations where a brand name is substituted.
 
Design/Methodology/Approach:  To achieve this goal, a quantitative study was conducted among 351 Tunisian consumers to test the hypotheses and quantify the impact of each variable.
 
Findings: The results of this research highlight three variables that can contribute to building consumer trust during a retailer brand name substitution, namely: (1) communication about the change; (2) perceived similarity and (3) perceived benefits derived from the change. The results also indicated that consumer attachment has a moderating effect on the relationship between trust and its determinants. More precisely, the stronger the attachment to the initial retailer brand, the more the consumer's trust in the brand decreases after the brand substitution.
 
Research, Practical & Social implications: This paper assists practitioners in identifying the key success determinants that can facilitate the transfer of consumer trust from the old retailer brand to the new one. It provides guidance for a successful retailer brand name substitution.
 
Originality/Value: This research fulfils an identified need to study how consumers’ trust in a brand can be transferred successfully in the case of a retailer brand name substitution.
Punctually universal structures
Authors:   , Guo Songqi
Published: January 2024

We investigate the primitive recursive content of various classical universalitytype results in algebra and combinatorics, including the algebraic closure theorem, the universality of the dense linear order, and the random graph, all with respect to primitive recursive isomorphic embeddings in the respective classes. In the case of fields, we show Rabin’s result can be improved to give a primitive recursive embedding of a punctual field into a punctual algebraic closure. In the case of linear orders, we show the analog of Rabin’s theorem using the linear order that obtained from the given one by densifying the adjacency intervals. We also show that in the computable setting, decidability of the adjacency relation describes the uniqueness of this ‘densification’ over the given order. In the case of the random graph, we prove the result in presence of primitive recursive Skolem function. We also show that, in contrast with an earlier result of Melnikov and Ng, it makes the notion of the random graph punctually robust.

Objective: Scientific reasoning is one of the most essential skills in learning biology and can be trained by integrating local wisdom. The lack of learning media that facilitates student learning causes low students' scientific reasoning skills. The development of learning media that integrates local wisdom is needed to train students' scientific reasoning. Method: The e-Book development procedure uses the ASSURE model which consists of six stages namely (1) analyze learner characteristics, (2) state objectives, (3) select, modify or design media, (4) utilize media, (5) requires learner responses, dan (6) evaluate. Data collection was collected by validation, observation, tests, and student response questionnaires. The One-Group Pretest-Posttest Design was implemented at Muhammadiyah 10 High School Surabaya for the 2022/2023 school year.  Results: The results showed that (1) the developed e-book was valid with an average validity value of 93%, (2) learning implementation was 92.5% at the first meeting, and 81% at the second meeting with the high category, (3 ) student learning outcomes in the scientific reasoning indicator increased to 88% in probabilistic reasoning, 82% in theoretical reasoning, 80% in correlation reasoning and 79% in proportional reasoning, as well as the n-Gain calculation results which with high criteria and (4) positive student responses to the use of e-books. So that the developed e-book is feasible to use in terms of local wisdom potential, e-book validity, practicality, and e-book effectiveness.  Novelty: The development of an e-book on ecosystem material with the integration of local wisdom from fish ponds to train scientific reasoning skills has never been done before.

Data collection techniques used digital literacy questionnaire instruments, learning outcomes tests, and interviews. Results: The results showed that the n-gain of students’ digital literacy and learning outcomes were medium criteria and high criteria, respectively. Thus, the developed physics teaching materials through guided discovery learning are effective for improving students' digital literacy. Novelty: Previous studies have not used guided discovery on work and energy teaching material to train students' digital literacy.
Variation in perceptions of the aesthetics of new suburban developments
Authors: Ma Mingming , Kirkpatrick James
Published: January 2024

Although the nature and correlates of variability in perceptions of the visual aesthetics of rural and natural landscapes have been well-studied, more work is needed on suburban landscapes, particularly to establish the desirable visual aesthetic qualities of new suburban developments. Visual elicitation was used to determine the aesthetic responses of adults of varying place of residence, occupation, gender and age to landscape-scale attributes of new suburban developments. A questionnaire was answered by a global sample of respondents who gave their sociodemographic details and ranked their preferences for different aesthetic attributes of suburban development. Australians and professionals were more likely than other nationalities and blue-collar workers to select the bottom of the hill, rather than the top of the hill. Professionals and those over 44 years old preferred naturalistic suburban boundaries rather than the geometric boundaries preferred by young white-collar workers. Younger respondents preferred one style of house in the suburb compared to three or more styles preferred by older respondents. Most respondents preferred low-density housing. House colour preferences varied by nationality, occupation, age and gender. These preferences may help planners to adjust the attributes of new suburban developments to cater for different subsets of people. Collaborative planning with local people will be necessary to maximise the aesthetic utility of new suburban developments.

Published: January 2024

This article corresponds to an action research which explored the contribution of information gap activities to support a group Honduran ninth-graders’ speaking fluency. Their speaking fluency was assessed in terms of speech rate, breakdowns or pauses, and repairs. This study adopted a mixed method approach: quantitative and qualitative. The sample chosen was a purposive sample made up of a group of seven ninth graders who had been learning English in rural context in a public high school in Comayagua for two years, all aged between 14 and 15 years old, with an A1 level.The information gap technique was implemented during seven sessions following the regular topics scheduled for the school term. Data were collected by applying a pre-test and a post-test to assess students’fluency, and results were assessed with an analytic rubric; and their perceptions were assessed by a focus group. The pre and post-test results showed an improvement in participants’ speaking fluency, and these results were in agreement with their positive perceptions. Moreover, participants expressed that information gap activities had impacted positively their motivation and their awareness of mistakes. In conclusion, information gap activities helped learners improve their speaking fluency and might support English teachers in Honduran rural public contexts not to rely upon traditional textbook use and make their classes more motivating and communicative.
