Experimental Techniques and Rock Physics Modeling to Study the Effects of Mineral Content and Thermal Maturation on Elastic Properties of the Organic-Rich Shale: Case Study of the Longmaxi Formation
Authors: Tuzingila Romulus Mawa , Kong Lingyun , Kasongo Ruben Koy
Published: February 2025

To evaluate favorable fracturing locations and layers of shale gas reservoirs, it is essential to comprehend how thermal maturity and mineral composition affect geomechanical characteristics. The effects of kerogen thermal maturation on elastic properties of organic-rich shale under consideration of the vitrinite reflectance and how it relates to kerogen density and organic porosity demand in-depth investigation. We propose rock physics modeling of heterogeneous shale rock samples to model kerogen as a function of thermal maturity and elastic properties as a function of shale composition. Nine Longmaxi shale samples from different depths of Well A were collected and tested by using X-ray diffraction (XRD), light microscope, open system pyrolysis gas chromatography, nanoindentation, and uniaxial-triaxial compression techniques to examine mineralogy, geochemical, and geomechanical characteristics. Using the Voigt-Reuss-Hill average and differential effective medium approach, shale matrix was modeled first and incorporated kerogen matter in terms of incremental thermal maturation. The acoustic characteristics of Longmaxi laminated shale affected by the thermal maturation were also studied using the Hudson model. The results indicate that the Longmaxi shale is part of highly brittle hard rocks; more brittle minerals increase their strength. As clay minerals increase, we observe that at 10-MPa confining pressure, triaxial compression strength (TCS) decreases from 72 MPa to 43 MPa in the Longmaxi upper member sample (SUM), 63 MPa to 39 MPa in the Longmaxi middle member sample (SMM), and 55 MPa to 36 MPa in the Longmaxi lower member sample (SLM). However, with the rise of the quartz + carbonate + feldspar mineral group, we observe an increase in TCS, which goes from 58 MPa to 75 MPa in the SUM, 52 MPa to 68 MPa in the SMM, and 48 MPa to 66 MPa in the SLM. Research indicates that the effective modulus and P-wave velocity of Longmaxi shale falls with increasing of Ro from 0 to 3. In the SUM, Young’s modulus decreased from 11.4 GPa to 1.3 GPa. SMM shows a reduction of Young’s modulus from 11.1 GPa to 0.5 GPa, while SLM shows a decrease from 10.9 GPa to 1.14 GPa. Also, the Vp falls from 5.63 km/s to 4.2 km/s, while the Vs decreases from 3.4 km/s to 2.16 km/s in the SUM. However, in the SMM, Vp decreases from 5.58 km/s to 4.22 km/s, and Vs falls from 2.9 km/s to 1.7 km/s, while Vp and Vs are reduced in the SLM. The results of our modeling approach are confirmed by the variation of elastic properties measured in the laboratory and interpreted in well logs, which show a satisfying validity and usefulness. However, given the extreme variety of reservoir characteristics and basin evolution conditions, we also recommend that it be locally calibrated when applied to particular shale reservoirs.
A Lucky Opportunity: First-ever Confirmation of Highly Individualized Egg Retrieval (HIER) in a Natural Conception Cycle
Authors: Gayete-Lafuente Sonia
Published: February 2025

To prevent oocyte-toxic premature luteinization of follicles during IVF cycles, which occurs earlier and earlier with advancing female age, our center has learned to advance oocyte retrieval appropriately over the last decade, a process we have given the acronym HIER (Highly Individualized Egg Retrieval). In principle, for practical reasons, the HIER concept was only applicable in IVF cycles. However, as a consequence of several lucky coincidences, we recently had the opportunity to apply HIER to a spontaneous conception. We here report this case to demonstrate that the HIER approach appears to be applicable independent of whether ovaries are exogenously stimulated or not. This case report expands utilization of HIER beyond IVF to practically all treatment cycles in infertility, in the process contradicting two long-held dogmas in worldwide infertility practice.
Machine Learning Models for Subarachnoid Hemorrhagic Prognosis: A Multicenter Study Considering Circadian Rhythms and Timing Factor
Authors: liu Yongbo , yang Chengbao
Published: February 2025

BACKGROUND:
Traditional statistical methods(e.g.,logistic regression)are widely used for prognostic prediction in SAH patients but may fail to capture complex non-linear interactions,such as between circadian rhythms and physiological parameters.Machine learning algorithms,particularly SVM with SHAP interpretability,offer a robust framework for handling high-dimensional data and improving predictive accuracy.This study innovatively integrates circadian rhythm-based time intervals(4-hour segments)into the model,addressing a gap in existing tools.
METHODS:
SAH patient data were obtained from the MIMIC-IV 3.1 ICU database and Liaoyang Central Hospital NICU(2018–2024)and divided into training(85%)and validation(15%)sets.Risk factors were screened using LASSO.Six machine learning models—LASSO regression,logistic regression,SVM,KNN,Decision Tree,and Random Forest—were developed and evaluated via 10-fold cross-validation."
RESULTS:
A total of 651 SAH patient data were analyzed(555 for training,96 for validation).Key factors including gender,age,admission time,smoking,diabetes,GCS,HR,SBP,and RPP were used to build the models.The SVM model,chosen for its high interpretability,achieved AUCs of 0.9351 and 0.7958,and F1 scores of 0.8496 and 0.7652,outperforming other models.A risk score calculator based on the SVM model is available at https://liuyongbo0312.shinyapps.io/myshinyapp/
CONCLUSION:
This study developed a predictive model for the prognosis of subarachnoid hemorrhage(SAH)patients using machine learning and identified Support Vector Machine(SVM)as the optimal model.The study found that the time of onset has a certain impact on prognosis,offering new directions for future research and clinical practice. Clinicians can use the SVM model by inputting patient-specific parameters(e.g.,RPP,GCS,admission time segment)into the provided calculator to rapidly identify high-risk patients for targeted interventions.
The influence of consumer, manager, and investor sentiment on US stock market returns
Authors: Manuel Nogueira Reis Pedro , Pedro Soares Pinto Antonio , Guimaraes Andre
Published: February 2025

This study examines how consumer, investor, and manager sentiment explain US stock excess returns over 23 years. Its novelty resides in integrating the sentiments of three different types of economic and financial agents. It also performs a segmented temporal analysis using rolling window techniques, to assess sentiment’s impact across different time horizons. The empirical analysis utilizes the Paris-Winsten and Newey-West estimators, along with the ARMAX model to address autocorrelation and heteroscedasticity in linear regression, providing robust standard errors and reliable statistical inferences. The autoregressive moving average models estimate excess return based on the past values, shocks, and external variables. Combining the Fama-French five-factor model with the sentiment factor enriches the analysis. The study’s findings indicate that higher consumer optimism negatively impacts excess returns, as investors may anticipate a future decline in the stock market due to an existing overheated economy. Investor sentiment exhibits mixed behavior, where higher uncertainty may increase stock returns due to previous oversold markets creating opportunities for investors or due to the closing of short positions, which will also increase stock demand. It is also related to decreased stock returns depending on the proxy used. As for managers’ sentiment, this work did not demonstrate a relevant relationship between this sentiment and stock returns. The study also reveals that the importance of sentiment determinants of those three agents changes over time. The findings support behavioral models of asset pricing, which incorporate both market fundamentals and the psychological characteristics (sentiment) of different market participants.

Published: February 2025

A comunicação familiar é fundamental no desenvolvimento saudável de crianças e adolescentes. Porém, existem fatores que prejudicam a comunicação familiar, como é o caso da psicopatologia parental. Dada a escassez de literatura no que concerne a este tipo de relação, o presente estudo tem como principais objetivos: explorar a associação entre os traços de personalidade que constituem a Tríade Negra e os diferentes tipos de comunicação parental, verificar as diferenças dos traços de personalidade que comportam a Tríade Negra em função do sexo e analisar o papel preditor da Tríade Negra na comunicação parental. A amostra foi constituída por 290 pais de crianças/adolescentes em idade escolar entre os 7 e os 16 anos de idade, composta por 231 participantes do sexo feminino e 59 do sexo masculino, com idades compreendidas entre os 28 e os 66 anos. Foram utilizados como instrumentos a Escala Dark Triad Dirty Dozen (TN-12), a Escala de Avaliação da Comunicação na Parentalidade – versão para pais (COMPA-P) e um questionário sociodemográfico. Os principais resultados sugerem que o narcisismo está negativamente associado a todas as dimensões da comunicação parental, enquanto o maquiavelismo não está associado a nenhuma dimensão, a psicopatia está negativamente associada à expressão da afeto e apoio emocional e a psicopatia prediz algumas dimensões da comunicação parental. Em suma, os resultados tornam-se pertinentes no desenvolvimento de formações/programas para profissionais de saúde, a fim de sensibilizar sobre a magnitude desta problemática, as suas consequências e fornecer ferramentas para avaliar e intervir.

Access to clean water is vital for public health; however, many urban households suffer from waterborne illnesses due to contamination. This study examines the economic cost of contaminated water to households in Khurda (Odisha) and Paschim Medinipur (West Bengal), focusing on diseases like diarrhea, vomiting, abdominal pain, and fever. Using a detailed questionnaire, data were gathered from 281 households. Findings show that 17% of households with piped water reported illness compared to 5.26% with non-piped water, with issues such as foul smell and red water also noted. The average household cost of illness is ₹47.69 (US$ 0.571), highlighting the need for improved water infrastructure and sanitation to address public health risks.
Social perception and challenges of light greywater reuse at the household level in developing countries: A case study of Bucaramanga, Colombia
Authors: Burgos-Arias Jessica , Cristina Rey-Romero Daniela , Oviedo-Ocaña Edgar Ricardo
Published: February 2025

Light greywater (LGW) has significant potential for reuse at the household level compared to other domestic wastewater effluents. However, social acceptance remains a major barrier to its implementation. This study provides a novel analysis of domestic water consumption habits and public perceptions of LGW reuse within an urban residential area in Latin America. Data were collected through a household survey (n = 132) and analyzed using descriptive and inferential statistics. Seventy-four per cent of respondents were willing to adopt this water reclamation scheme. Education level significantly influenced perceptions of reuse, while gender and age had no significant effect. Personal attitudes, self-perceived capacity, and water consumption habits, particularly the frequency of handwashing, tooth brushing, and toilet flushing, were key drivers of the LGW generation and shaped public perceptions. Higher per capita water consumption associated with these activities underscores the feasibility of LGW reuse, particularly for most preferred applications like toilet flushing (81%) and floor cleaning (67%), which involve minimal human contact. Most respondents expressed willingness to invest in LGW reuse systems (73%), perform operational tasks (77%), and conduct maintenance activities (64%). The study identified five challenges hindering LGW reuse at the household level and proposed strategies to address them in the Colombian context.

Authors: Chandel Namrata , Agnihotri Prasit Girish , Patel Jayantilal N.
Published: February 2025

Flood frequency analysis (FFA) is essential for effective flood risk management, predicting flood event probabilities over time. The Generalized Additive Models for Location, Scale, and Shape (GAMLSS) technique is used in this study to get around the problems with traditional FFA methods, which usually rely on stationarity and well-known distributions. The objectives are to conduct a comprehensive flood frequency analysis of the Upper Narmada River Basin using GAMLSS and improve flood risk assessments considering non-stationary data and covariates like rainfall, temperature, and land use changes. The study collects and analyses hydrological and meteorological data. Change points are identified using the Pettitt test, and trends are analyzed with the modified Mann–Kendall test. The Pettitt test results indicate significant change points, while the modified Mann–Kendall test reveals decreasing trends in all stations, with p-values ranging from 0.00251 to 0.6985. GAMLSS model's goodness-of-fit is assessed using various probability distributions, including gamma, Weibull, Gumbel, logistic, and log-normal. The log-normal distribution performs best in four stations, while Weibull and Gamma are optimal in others. Model selection is based on the Akaike Information Criterion (AIC), with values ranging from 508.14 to 663.

A Lei nº 10.639 de 2003 instituiu a obrigatoriedade do ensino de história e cultura afrobrasileira e africana nos currículos da educação básica em todo o território nacional. A investigação versa sobre a implementação da referida lei na Escola Estadual Professor Abel Freire Coelho, na cidade de Mossoró/RN, e tem como sujeitos da pesquisa cinco professores/as do ensino médio da instituição. Para o desenvolvimento do estudo, a metodologia empregada foi a etnografia escolar – uma adaptação do método etnográfico para as pesquisas no âmbito educacional – cujas etapas são as visitas na escola, as observações in loco, conversas informais, questionários, bem como a realização de entrevistas semiestruturadas com cinco docentes das disciplinas de Artes, Língua Portuguesa, Língua Espanhola, História e Sociologia, para identificar a presença da temática a partir das percepções deles/as. Outrossim, para o alcance dos objetivos estabelecidos no estudo, foram analisadas as Diretrizes Curriculares Nacionais para a Educação das Relações Étnico-Raciais e para o ensino de história e cultura afro-brasileira e africana e o projeto político-pedagógico da escola. Como referencial teórico, busca-se arrimo em Fernandes (1978), Gomes (2005), Munanga (2012), Munanga; Gomes (2016), Nascimento (1982), Ribeiro (2014), para estudar a questão do racismo no Brasil, Movimento Negro, cultura, identidade e diferença; Silva (2017), Lopes (2008) e Macedo (2012) para discutir currículo e diretrizes curriculares, bem como André (2000) e DaMatta (1978), para embasar a pesquisa etnográfica. Levando-se em conta o que foi observado na escola, bem como a análise das entrevistas realizadas com os/as docentes, verificamos que a escola implementa parcialmente os preceitos estabelecidos na Lei nº 10.639 de 2003, uma vez que o projeto político-pedagógico não contempla expressamente a temática prescrita na legislação
Analyzing Themes, Sentiments, and Coping Strategies Regarding Online News Coverage of Depression in Hong Kong: Mixed Methods Study
Authors: Chen Sihui , Ngai Cindy Sing Bik , Cheng Cecilia , Hu Yangna
Published: February 2025

Background

Depression, a highly prevalent global mental disorder, has prompted significant research concerning its association with social media use and its impact during Hong Kong’s social unrest and COVID-19 pandemic. However, other mainstream media, specifically online news, has been largely overlooked. Despite extensive research conducted in countries, such as the United States, Australia, and Canada, to investigate the latent subthemes, sentiments, and coping strategies portrayed in depression-related news, the landscape in Hong Kong remains unexplored.

Objective

This study aims to uncover the latent subthemes presented in the online news coverage of depression in Hong Kong, examine the sentiment conveyed in the news, and assess whether coping strategies have been provided in the news for individuals experiencing depression.

Methods

This study used natural language processing (NLP) techniques, namely the latent Dirichlet allocation topic modeling and the Valence Aware Dictionary and Sentiment Reasoner (VADER) sentiment analysis, to fulfill the first and second objectives. Coping strategies were rigorously assessed and manually labeled with designated categories by content analysis. The online news was collected from February 2019 to May 2024 from Hong Kong mainstream news websites to examine the latest portrayal of depression, particularly during and after the social unrest and the COVID-19 pandemic.

Results

In total, 2435 news articles were retained for data analysis after the news screening process. A total of 7 subthemes were identified based on the topic modeling results. Societal system, law enforcement, global recession, lifestyle, leisure, health issues, and US politics were the latent subthemes. Moreover, the overall news exhibited a slightly positive sentiment. The correlations between the sentiment scores and the latent subthemes indicated that the societal system, law enforcement, health issues, and US politics revealed negative tendencies, while the remainder leaned toward a positive sentiment. The coping strategies for depression were substantially lacking; however, the categories emphasizing information on skills and resources and individual adjustment to cope with depression emerged as the priority focus.

Conclusions

This pioneering study used a mixed methods approach where NLP was used to investigate latent subthemes and underlying sentiment in online news. Content analysis was also performed to examine available coping strategies. The findings of this research enhance our understanding of how depression is portrayed through online news in Hong Kong and the preferable coping strategies being used to mitigate depression. The potential impact on readers was discussed. Future research is encouraged to address the mentioned implications and limitations, with recommendations to apply advanced NLP techniques to a new mental health issue case or language.
Evolving Artistic Inclinations in Vikram Seth’s Poetry
Authors: Geetha Geetha
Published: February 2025

Vikram Seth's poetry has changed a lot over the years. At first, he used formal styles with strict rules for rhythm and rhyme. But later, he started trying out new things, like free verse and different types of poetry. This shift shows how he has grown as a poet, letting him explore deeper feelings and bigger ideas. In his newer poems, Seth pays a lot of attention to how words and their structure work together to create meaning. This shows that he keeps challenging himself as a poet and keeps finding new ways to make his poetry richer and more interesting. In Vikram Seth's poetry, he often uses traditional forms like sonnets with rhyme and meter. He tends to focus more on the beauty of nature and common things rather than himself. Even when he addresses serious topics, his writing feels light and refreshing.

Áreas verdes urbanas disponibilizam inúmeros benefícios para o bem-estar humano e qualidade de vida e apresentam importantes funções de estoque e sequestro de carbono, que contribuem para a mitigação e adaptação das cidades às mudanças climáticas. Um expressivo número de estudos tem sido realizados em áreas verdes urbanas dentro da Mata Atlântica, para avaliar e descrever sua contribuição na produção de biomassa. Por isso, o objetivo deste trabalho foi estimar a biomassa e o estoque de carbono no Horto do IFRJ campus Nilópolis. A estimativa da biomassa aérea, das raízes e do solo foi realizada a partir de três equações. Para a biomassa vegetal, foram obtidos dados de altura, diâmetro na altura do solo e a densidade do caule. Para o estoque de carbono no solo, foram obtidos dados das variáveis densidade, teor de carbono e profundidade. Foram identificados 352 indivíduos, divididos em 42 espécies herbáceas e 41 espécies arbustivas. As alturas e os diâmetros dos indivíduos variaram de 0,6 cm a 15 m (Média = 1,39 m)  e 0,2 cm a 50 cm (Média = 5,05 cm), respectivamente. O Horto do IFRJ Nilópolis estoca 1,69 toneladas de biomassa (0,8 toneladas de carbono) na sua parte aérea e 0,33 toneladas nas suas raízes (0,14), com a predominância (96%) no estrato arbóreo. O solo do horto estoca 226 quilos de carbono (6,27 Kg/m2). A medição da densidade em laboratório para estimativa da biomassa é uma ferramenta importante para aumentar a confiabilidade dos valores estimados. A quantidade de biomassa e carbono estocado na área de estudo é similar a outras áreas verdes, mostrando a importância dessa área como recurso urbano de mitigação e adaptação climática, que deve ser usado como modelo para o planejamento e engajamento das instituições de ensino.

Published: February 2025

Contextualización: las prácticas agroecológicas de manejo como la biofertilización son herramientas viables para mejorar la productividad de los cultivos de pequeños y medianos productores de especies vegetales alimenticias. Estas prácticas aumentan la disponibilidad de nutrientes para las plantas, haciendo uso de recursos propios de la naturaleza como los desechos orgánicos de origen animal y vegetal, así como minerales y microorganismos que solos o combinados, en formas líquidas o sólidas, ayudan a mejorar el suelo y la nutrición vegetal. Vacío de conocimiento: ante el efecto negativo de las prácticas intensivas de fertilización inorgánica, surge la necesidad de implementar estrategias agroecológicas de biofertilización dirigidas a una producción de alimentos más eficiente, en el marco de sistemas ajustados a requerimientos de calidad, inocuidad y sostenibilidad ambiental, con los que se logre una mayor aceptación para su comercialización y consumo. Propósito: el principal objetivo de este estudio fue evaluar un caldo microbiano orgánico-mineralizado y los efectos de su aplicación sobre el crecimiento y desarrollo de Capsicum pubescens Ruiz & Pav., y Solanum muricatum Aiton, especies altoandinas promisorias de Bogotá D.C. Metodología: se elaboró y caracterizó química y microbiológicamente un caldo microbiano obtenido de una fermentación aeróbica en soporte orgánico mineral. El caldo se aplicó a plántulas de C. pubescens y S. muricatum de forma edáfica (drench) en concentración del 10% a los 21, 42, 63, 85 y 106 días del trasplante. Se evaluaron 4 tratamientos y 30 réplicas. Las variables evaluadas fueron altura de la planta, número de hojas, diámetro del tallo e incidencia de afectaciones foliares. El experimento se analizó a través de un diseño en bloques completamente aleatorizado, en el que el factor de bloqueo correspondió a los días en los que se realizó la aplicación y seguimiento de los tratamientos; y la validación de los supuestos del modelo se realizó para cada una de las variables de respuesta. Resultados y conclusiones: en cuanto a la composición química y microbiológica del biofertilizante a base de equinaza, se encontró que contiene una gran variedad de nutrientes, macro y microelementos, así como microorganismos esenciales para el equilibrio en la nutrición de las plantas. En el efecto sobre el crecimiento, desarrollo y sanidad de las plantas, el biofertilizante mostró ser el segundo mejor tratamiento después del testigo químico. Para una mayor efectividad, los caldos microbianos orgánicos -mineralizados conviene aplicarlos periódicamente para asegurar la multiplicación y activación de los microorganismos introducidos y promover la actividad microbiana nativa.

Lo «stato di salute» del neutro di materia in area mediana: alcuni dati da cinque punti linguistici
Authors: Virgili Sarah
Published: February 2025

Los dialectos italorromances centrales y meridionales difieren de la mayoría de las lenguas romances estándar por la presencia de sistemas de género gramatical más complejos, con cuatro valores en lugar de dos. De hecho, además del género masculino y femenino tenemos el llamado neutro alternante y el neutro de masa, ambos sucesores del neutro latín. En el centro de Italia, la diferencia entre neutro de masa y masculino está señalada a través del contraste entre -/o/ y -/u/. Esta oposición no es siempre (y no en todas partes) estable debido a una serie de fenómenos fonológicos y morfológicos y, en parte, también a causa de la presión del italiano estándar (en el que -u, -o > -o). Todo esto genera repercusiones en la resistencia de la oposición entre masculino y neutro, un valor de género que, asimismo, tiende a agotarse desde hace mucho tiempo según una dinámica centenaria que ha afectado a todas las lenguas romances. Gracias al estudio de los datos recopilados a través de encuestas lingüísticas en cinco localidades, distribuidas en tres regiones diferentes del centro de Italia (Lacio, Umbría y Marche), hemos intentado ilustrar cuáles son las posibles dinámicas que conducen a la reducción -u > -o y qué tipo de impacto tiene esto en la señalización del neutro. Los resultados obtenidos, que consideran tanto la dimensión del léxico como la dimensión de la morfosintaxis, muestran una situación considerablemente heterogénea: algunos dialectos, como el umbriano de Foligno, muestran un nivel bastante avanzado de erosión del neutro, mientras que otros, como el belmontese (hablado en la región de las Marcas), todavía revelan su productividad.

Published: February 2025

The article is devoted to the consideration of education as a social institution and the peculiarities of institutional, social and managerial context, in which its features are manifested at the present stage.The authors analyze diff erent formats of education, identify common patterns and specifi c factors that have determined its transformation. The authors distinguish two classes of education matrices — individual and group learning. The matrices of individual learning include: 1) self-education, 2) mentoring, 3) governess and tutoring, 4) tutoring; the matrices of group learning include: 1) mass education, 2) traditional education, 3) adult education, 4) the matrix of “turquoise” education. The article characterizes the components of institutional matrices in detail.The authors believe that looking at the development of education in the context of changing institutional matrices is fundamentally important from the perspective of social management. The article, based on the consideration of the institutional context of the educational process, reveals the current problems of social management in the fi eld of education and proposes some directions of institutional transformation.In particular, the authors consider the expansion of opportunities for individual education (tutoring and mentoring), active development of elder education in accordance with the concept of lifelong learning, equalization of the status of paid and free education, as well as the active use of information and communication technologies and AI in the educational process. The authors believe that the proposed measures will make it possible to supplement the traditional matrix of education, reducing its negative eff ects, which will serve to expand learning opportunities for all categories of the population and improve the quality of education in general

Objective: The objective of this study was to design a Water Quality Index (WQI) sensitive to the limits established by current legislation, focusing on the sustainable management of urban water bodies.
 
Theoretical Framework: The research addresses the importance of regionalizing water quality indices to improve the monitoring of urban water management. Furthermore, it highlights that the indices used in urban streams lack good sensitivity to isolated parameter variations, which justifies the need for a new index.
 
Method: The development of the new WQI consisted of four stages: parameter selection, normalization method, weight selection, and aggregation method. The initial parameters, such as total nitrogen, total solids, and temperature, were replaced by ammonia, nitrate, and surfactants. Normalization curves were also created, and the parameter weights were adjusted.
 
Results and Discussion: The WQIBHU (IQABHU) demonstrated greater sensitivity to parameter variations compared to the WQICETESB (IQACETESB), with the exception of the ANH-01 point. Most of the quality values of the IQABHU were lower than those of the IQACETESB, indicating non-compliance with legal limits for urban stream classes. The IQABHU showed better performance in turbidity and dissolved oxygen (DO), while the IQACETESB masked the real water quality conditions, especially regarding the E. coli parameter. The new "±" tool allowed for more detailed monitoring of water quality, making the IQABHU more suitable for continuous monitoring and supporting decision-making by the competent authorities.
 
Research Implications: The research has significant practical implications, as the proposed new WQI can be used as a tool to improve urban water management, contributing to the sustainability of water bodies and ensuring compliance with current environmental legislation.
 
Originality/Value: The value and originality of this work lie in the proposal of a more sensitive index adapted to the reality of urban water bodies, using a systematic methodology for modifying and improving parameters and weights, which could represent an important advancement in water quality management.

Diagnosis is considered the determining step for success or failure in orthodontic treatment and must be performed considering heredity, individual characteristics, and the patient’s environment, both for corrective and interceptive orthodontics. To establish a sequence and associate relevant information that defines a treatment plan, the facial, occlusal, cephalometric, and anamnesis (FOCA) diagnostic method was created. This method is actively used by more than 3000 dentists and its instruments have already been shared with more than 110,000 dentists in Brazil and Latin America, through online events. This article aims to describe the methodology and instruments created for its application. The 13-step facial analysis guide, occlusal analysis in the transverse, vertical, and sagittal directions, as well as inter and intra-arch analysis, are described in this work. The anamnesis guide instrument highlights heredity, medical history, menarche, habits, trauma, tooth loss, breathing, speech changes, snoring, bruxism, and TMJ function deviations. The sequence of what to do with the information obtained through facial and occlusal analysis is described in this work: The elaboration of therapeutic goals, list of problems, alternative approaches, and final treatment sequence. The FOCA diagnostic method guarantees a disciplined approach to diagnosis and treatment planning. The systematization of information, as well as the implementation of technology in the diagnostic steps, justifies treatment decisions and leads the professional to more complete and assertive treatment plans.

Trans/forming the Greek theatrescape: Translation for performance as representation
Authors: Misiou Vasiliki
Published: February 2025

This paper explores the translation and staging of Paloma Pedrero’s La llamada de Lauren… in Greece (2017–2019). The play was staged at a time marked by conflicting forces: on the one hand, Greece was taking significant steps forward for transgender people, recognising basic rights and freedoms, and on the other, discriminatory practices and gender-based violence were still a very present reality. In this context, Fenia Apostolou, a director who made headlines with her story as a trans person, and Maria Hatziemmanouil, a well-known translator of Spanish theatre, decided that it was the right time to stage Pedrero’s play. Based on the agenda pursued by the agents themselves, as reflected in the paratextual materials studied, the present paper discusses the role of translation for performance in going against prevailing normative practices and constraints, ultimately effecting change. The study shows that Hatziemmanouil sees translation as a performative, transcultural, and political practice. Thanks to her translation and Apostolou’s staging, systemically underrepresented groups have become more visible, and the discussion regarding gender, sex(uality) and identity in Greece has been enhanced, proving that translation and/for performance can contribute to the trans/formation of perceptions and major changes in societies.
Translating Topdog/Underdog, by Suzan-Lori Parks: Just another ‘Rep & Rev’?
Authors: Salzmann Kathinka
Published: February 2025

This article explores some of the main challenges one has to deal with when translating a play whose language — African American Vernacular English — is linked to a specific context and culture, as is the case with Topdog/Underdog (1999), by the African American dramatist Suzan-Lori Parks. In particular, I shall seek to establish how a notion such as the ‘politically correct’ is questioned by the translatorial process, thus emphasising the translator’s ethical responsibility, while also showing how Parks grounds her writing in the idea of ‘repetition and revision’ characteristic of the Jazz aesthetic.
An alien among aliens: Translating multicultural identities in Singapore’s contemporary theatre
Authors: Hu Bei
Published: February 2025

This article explores the conﬂated roles of translator and playwright embodied by Kuo Pao Kun (1939-2002), a doyen figure acclaimed as the embodiment of Singapore’s contemporary theatre. As a Singaporean arts activist born in China, Kuo reformulated the state identity of Singapore through his self-translated play Descendants of the eunuch admiral (1995a), which examines his perceptions regarding the perils of a homogenised national theatrical realm and the tensions emerging from modernisation — an intriguing standpoint for an ethnically Chinese art activist. This lyrical episodic play unfurls the representation of the self-discovery of Zheng He, the Chinese admiral and court eunuch during the Ming Dynasty (1368–1644). Stratified into prose and verse, it weaves tales and metaphors that highlight the dissolution of cultural identities, and the societal challenges faced due to emasculation. This study focuses on Kuo’s translator intervention in the bilingual versions of the play, one staged in English in June 1995 and the other in Mandarin Chinese in August 1995. It reveals Kuo’s proposition of multiculturalism as a counternarrative to the official discourse of multiracialism propagated by the authorities, uncovering how playwrights represent as translation agents within multilingual narratives.

The moral values and local wisdom contained in folklore can be used as a communication tool to teach educational values, and can also be used as a learning resource in schools. This research aims to determine the feasibility of a flipbook that highlights the diversity of animals in the Ne' Baruakng Kulub folklore in the Animal Group sub-material. The method used is research and development (R&D) according to Borg & Gall. The steps used include 3 of 10 stages, namely research and gathering information through studying literature related to animals found in folklore, followed by planning to formulate learning objectives which will be mediated by flipbook media in accordance with basic competencies, and developing initial forms of product by making a flipbook according to the results of research and gathering information and planning. The flipbook media product was assessed by 5 validators consisting of 2 Biology Education lecturers and 3 Science teachers. Data analysis uses Content Validity Ratio (CVR) and Content Validity Index (CVI) referring to the Lawshe method. The folk tale "Ne' Baruakng Kulub" is presented in flipbook media in the form of a synopsis and the types of animals contained in the story are used as a means to link it to the learning material. The flipbook media was assessed as appropriate by the five validators on all criteria with CVR and CVI values equal to 1. Thus, the Animal Group Submaterial flipbook media based on the folklore "Ne'Baruakng Kulub" was suitable for use as a learning medium.
