Published: November 2024

Applied eDNA metabarcoding is increasingly being considered as a tool to inform management decisions, regulations, or policy development. Because these downstream considerations are coming to the forefront of eDNA applications, optimizing workflow elements is essential to increasing standardization, efficiency, and competency of metabarcoding results. Reference DNA sequences are critical workflow elements that currently lack consistent approaches to generating, curating, or publishing. We present a complete mitochondrial genome and nuclear ribosomal DNA cistron reference DNA sequence library for 92% of the freshwater fish species of British Columbia, Canada. This resource is published as the Novel Applied eDNA Metabarcoding Reference Sequences (NAMERS) repository (https://namers.ca), a user-friendly and interactive website for specialists and non-specialists alike to explore and generate custom reference libraries for taxa and genes of interest. We demonstrate the power of NAMERS for optimization of applied eDNA metabarcoding study design by analyzing the number of primer mismatches and species resolution power of existing metabarcoding markers. NAMERS demonstrates that high quality curated genomic information is within a reasonable reach to meet the increasing demand for actionable eDNA metabarcoding applications. The framework used here incorporating the pillars of accuracy, completeness and accessibility can be applied for new iterations of other reference sequence databases to bring DNA-based monitoring into a new era.
New technical solutions for the design of NPP passive safety systems
Authors: Soloviev Sergey L. , Zaryugin Denis G. , Kalyakin Sergey G. , Leskin Sergey T. , Soloviev Dmitry S.
Published: November 2024

The paper describes the new principle of passive NPP safety systems designing, in which the natural circulation of working fluid or gas is replaced by forced circulation in order to increase it’s capacity. The energy required by the system is converted from the emergency process itself, which this system resists when performing a given safety function. The goal is to expand the variety and capacity of passive NPP safety systems in order to optimize and reduce costs of NPP power units with various types of reactors while increasing the safety level. The proposed technical solutions are based on the use of direct non-mechanical conversion of the energy, comprised in emergency process, to electricity, and then to mechanical energy of hydraulic machine for working medium moving in a forced circulation mode. To demonstrate the proposed principles, the following technical solutions have been considered:

• new passive electrochemical hydrogen recombiner for NPPs with light water reactors. Application of new techniques allowed increasing the performance by weight of the recommended hydrogen simultaneously with increasing the hydrogen torch threshold, as well as other important characteristics;

• passive emergency core cooling system for heavy liquid metal cooled reactors. Application of new techniques allowed increasing the core remove heat capacity in order to scale down the main equipment;

• passive system for in-vessel core melt retention of Pressurized Water Reactors of high thermal capacity (more than 3000 MWe). Application of new techniques allowed increasing the system thermal capacity in order to be able to apply to high thermal power reactors like VVER-1000 and more.
L0-Norm based Image Pansharpening by using population-based algorithms
Authors: Günen Mehmet Akif , Pérez-Delgado María-Luisa , Beşdok Erkan
Published: November 2024

Earth observation satellites capture panchromatic images at high spatial resolution and multispectral images at lower resolution to optimize the use of their onboard energy sources. This results in a technical necessity to synthesize high-resolution multispectral images from these data. Pansharpening techniques aim to combine the spatial detail of panchromatic images with the spectral information of multispectral images. However, due to the discrete nature of these images and their varying local statistical properties, many pansharpening methods suffer from numerical artifacts such as chromatic and spatial distortions. This paper introduces the L0-Norm-based pansharpening method (L0pan), which addressed these challenges by maximizing the number of similar pixels between the synthesized pansharpened image and the original panchromatic and multispectral images. L0pan was optimized using a population-based colony search algorithm, enabling it to effectively balance both chromatic fidelity and spatial resolution. Extensive experiments across nine different datasets and comparison with nine other pansharpening methods using ten quality metrics demonstrated that L0pan significantly outperformed its counterparts. Notably, the colony search algorithm yielded the best overall results, highlighting the algorithm's strength in refining pansharpening accuracy. This study contributed to the advancement of pansharpening techniques, offering a method that preserved both chromatic and spatial details more effectively than existing approaches.
(Co-)fibration of generalized crossed modules
Authors: Akay Hatice Gülsün
Published: November 2024

Crossed modules are algebraic structures that generalize the concept of group extensions. They involve group-like objects (often groups or groupoids) with additional structure and mappings between them that satisfy certain properties. Generalized crossed modules further extend this concept to higher-dimensional settings or more general algebraic contexts. In this paper, we studied the fibration and co-fibration of generalized crossed modules.
Turing patterns in a networked vegetation model
Authors: Bao Xiaomei , Tian Canrong
Published: November 2024

A vegetation model composed of water and plants was proposed by introducing a weighted graph Laplacian operator into the reaction-diffusion dynamics. We showed the global existence and uniqueness of the solution via monotone iterative sequence. The parameter space of Turing patterns for plant behavior is obtained based on the analysis of the eigenvalues of the Laplacian of weighted graph, while the amplitude equation determining the stability of Turing patterns is obtained by weakly nonlinear analysis. We also show that the optimal rainfall is only determined by the density of the water. By some numerical simulations, we examine the individual effect of diffusion term on the formation of regular Turing patterns. We show that the large diffusion induces stable Turing patterns.
Sparse Network Asymptotics for Logistic Regression Under Possible Misspecification

, onto a vector of known functions of consumer and product attributes under asymptotic sequences where (i) both
N and
M grow large, (ii) the average number of products purchased per consumer is finite in the limit, (iii) there exists dependence across elements in the same row or same column of
Y (i.e., dyadic dependence), and (iv) the true conditional probability of making a purchase may, or may not, take the assumed logit form. Condition (ii) implies that the limiting network of purchases is
sparse: only a vanishing fraction of all possible purchases are actually made. Under sparse network asymptotics, I show that the parameter indexing the logit approximation solves a particular Kullback–Leibler Information Criterion (KLIC) minimization problem (defined with respect to a certain Poisson population). This finding provides a simple characterization of the logit pseudo‐true parameter under general misspecification (analogous to a (mean squared error (MSE) minimizing) linear predictor approximation of a general conditional expectation function (CEF)). With respect to sampling theory, sparseness implies that the first and last terms in an extended Hoeffding‐type variance decomposition of the score of the logit pseudo composite log‐likelihood are of equal order. In contrast, under dense network asymptotics, the last term is asymptotically negligible. Asymptotic normality of the logistic regression coefficients is shown using a martingale central limit theorem (CLT) for triangular arrays. Unlike in the dense case, the normality result derived here also holds under degeneracy of the network graphon. Relatedly, when there “happens to be” no dyadic dependence in the data set in hand, it specializes to recently derived results on the behavior of logistic regression with rare events and i.i.d. data. Simulation results suggest that sparse network asymptotics better approximate the finite network distribution of the logit estimator. A short empirical illustration, and additional calibrated Monte Carlo experiments, further illustrate the main theoretical ideas.
Privacy‐Preserving Signals
Authors: Strack Philipp , Yang Kai Hao
Published: November 2024

A signal is
privacy‐preserving with respect to a collection of
privacy sets if the posterior probability assigned to every privacy set remains unchanged conditional on any signal realization. We characterize the privacy‐preserving signals for arbitrary state space and arbitrary privacy sets. A signal is privacy‐preserving if and only if it is a garbling of a
reordered quantile signal. Furthermore, distributions of posterior means induced by privacy‐preserving signals are exactly mean‐preserving contractions of that induced by the
quantile signal. We discuss the economic implications of our characterization for statistical discrimination, the revelation of sensitive information in auctions and price discrimination.
Androgen receptor inhibitors in treating prostate cancer
Authors: Cole Ryan N , Fang Qinghua , Matsuoka Kanako , Wang Zhou
Published: November 2024

Androgens play an important role in prostate cancer development and progression. Androgen action is mediated through the androgen receptor (AR), a ligand-dependent DNA-binding transcription factor. AR is arguably the most important target for prostate cancer treatment. Current USA Food and Drug Administration (FDA)-approved AR inhibitors target the ligand-binding domain (LBD) and have exhibited efficacy in prostate cancer patients, particularly when used in combination with androgen deprivation therapy. Unfortunately, patients treated with the currently approved AR-targeting agents develop resistance and relapse with castration-resistant prostate cancer (CRPC). The major mechanism leading to CRPC involves reactivation of AR signaling mainly through AR gene amplification, mutation, and/or splice variants. To effectively inhibit the reactivated AR signaling, new approaches to target AR are being actively explored. These new approaches include novel small molecule inhibitors targeting various domains of AR and agents that can degrade AR. The present review provides a summary of the existing FDA-approved AR antagonists and the current development of some of the AR targeting agents.

Study and Comparison of the ph of the External Auditory Canal in Patients with Otitis Externa and Healthy Individuals
Authors: Yadav Krutika Vinay , Chethana R. , Gowda Vishwanath M. , Ghoshal Anuja
Published: November 2024

Context:

Otitis externa is the infection of epithelial lining of the external auditory canal (EAC). Cerumen has an acidic potential of hydrogen (pH) which accounts for its bactericidal and fungicidal property. The acidity of the EAC decreases due to high humidity, bathing, swimming, and frequent ear cleansing, which can lead to otitis externa.

Aims:

To study and compare the pH of EAC in patients with otitis externa and healthy individuals.

Settings and Design:

Tertiary care center and prospective, observational, and comparative study.

Methods:

This study includes 60 subjects with 30 diagnosed with otitis externa in diseased group and 30 in nondiseased group. pH of the EAC was evaluated by placing pH strips in outer one-third of EAC for 1 min.

Statistical Analysis Used:

Independent sample t-test was calculated using the Statistical Package for the Social Sciences version 24.0, IBM Corporation, USA for MS Windows.

Results:

Of the 60 subjects, 24 out of 30 subjects in diseased group had pH more than 5.6 and no subjects had pH more than 5.6 in nondiseased group. The average pH in diseased group was 8.73 ± 1.57 and nondiseased group was 5.13 ± 0.43.

Conclusion:

A change toward alkalinity of EAC is an important factor for the pathogenesis of otitis externa. Treatment of otitis externa should include acidification of the EAC with treatment with antibiotics and antifungals.
Mastoid Mucocele with Intracranial Complication Presenting as Acute Otomastoiditis
Authors: Aziz Nabilah Abd , Zainon Izny Hafiz , Johari Hafiza Husna , Othman Nik Adilah Nik
Published: November 2024

Mucocele is a benign epithelial-lined mucoid-filled sac that may sound harmless but has the potential of expanding at the expense of its surrounding bony architecture. The incidence of its emergence from the mastoid bone is relatively rare, whereas one that results in intracranial complications is almost unheard of. We present the case of a patient presenting with the symptoms of a middle ear infection, which was initially treated as refractory acute otitis media with intracranial complication. However, intraoperative findings revealed an infected mucocele within the mastoid bone.

Authors: Ayushree Ayushree , Richa Richa , Prasad Raj Kumar , Sharma Satyendra
Published: November 2024

Introduction:

Chronic otitis media (COM), affecting millions globally, remains a significant health concern despite antibiotic advancements. Evolving otological approaches focus on both dry ear attainment and hearing restoration. Grading systems such as middle ear risk index (MERI) can aid in stratifying disease severity and predicting surgical outcomes for effective patient management.

Aims and Objectives:

The study aimed to assess MERI scores in tympanomastoid surgery patients to categorize disease severity and evaluate its correlation with postoperative hearing improvement.

Materials and Methods:

A prospective study was conducted over 2 years on 50 patients of COM. Patients were categorized into three groups based on MERI scores developed by Becvarovski and Kartush. A preoperative audiometry was obtained. The type of middle ear surgery required for each patient was decided intraoperatively as per the findings. Patients were followed up for a 6-month period, and hearing improvement was assessed in terms of closure of air-bone gap in the postoperative audiogram. Statistical analysis was performed using SPSS v23 software for Windows, and P < 0.05 was considered statistically significant.

Results:

In our study, significant associations (P < 0.05) were observed between the “MERI category” and variables such as otorrhea, cholesteatoma, ossicular status, previous surgery, middle ear granulation/effusion, smoker, total MERI score, and surgery performed. MERI was found to be negatively associated with hearing improvement, the higher the score lesser the improvement in hearing, and vice versa.

Conclusion:

The incorporation of MERI scoring into the surgical evaluation of COM cases holds promise for improving patient care and treatment strategies.
Study Protocol for Assessing Serum Superoxide Dismutase Response to a Novel Head Rotation Maneuver in Posterior Canal Benign Paroxysmal Positional Vertigo Treatment
Authors: Dhiman Neetu Rani , Gyanpuri Vyom , Joshi Deepika
Published: November 2024

Background:

Benign paroxysmal positional vertigo (BPPV) is a condition with sudden onset which causes short episodes of severe vertigo on altering the position of the head. Superoxide dismutases (SODs) are antioxidant proteins that regulate oxidative stress response in the body. Through this study, we evaluate the role of SOD in causing BPPV and effect of a new alternating maneuver, head rotation maneuver, for the treatment of BPPV of the posterior canal in reducing oxidative stress levels.

Methodology:

For investigating the role of serum SOD in the occurrence of BPPV Posterior canal, 60 BPPV and 60 healthy controls will be recruited. Their serum samples will be collected and SOD levels will be evaluated through colorimetry. For evaluating the effectiveness of head rotation maneuver in reducing the oxidative stress, patients with posterior canal BPPV (PC-BPPV) will be enrolled and divided into two groups through random allocation. Both the groups will be treated with head rotation and Epley maneuvers, respectively, by two separate therapists. Post-therapy SOD level will also be assessed.

Results:

Two-way repeated measures analysis of variance will be used to compare the groups’ improvement; treatment measures will be referred to as intergroup variables. Binary logistic regression analysis will be used to determine how SOD levels affect BPPV and recurrent BPPV. Pre- and postmaneuver SOD level will also be compared.

Conclusion:

SOD can be established as a reliable and strong biomarker for the occurrence of BPPV. Moreover, head rotation maneuver which is easy to perform can be used for managing PC-BPPV if the results show promising outcomes.
Efficacy of Adjuvant Yoga Therapy for Cognition in Schizophrenia: A Systematic Review and Meta-analysis of Randomized Controlled Trials
Authors: Pattanashetty Daiveek G. , Varambally Shivarama , Bhargav Hemant
Published: November 2024

Background:

It is well-known that negative and cognitive symptoms in schizophrenia are challenging to treat with conventional psychotropics. Hence, various mind–body interventions like yoga have been brought into the modern scientific realm to investigate for possible benefits. Although several studies have been done using yoga as an intervention for cognition in schizophrenia, the results have been inconclusive. In this study, we systematically reviewed and performed meta-analyses of the eligible studies to investigate the efficacy of yoga as adjuvant therapy for cognition in the schizophrenia population.

Methodology:

After registration of the protocol in PROSPERO (CRD42024504319), electronic databases such as PubMed, MEDLINE, PsycINFO, Scopus, Cochrane Library, ClinicalTrials.gov, and gray literature were searched for randomized controlled trials from their date of inception till March 2024, with appropriate search terms. Covidence and Microsoft Excel for data extraction, Cochrane tool for risk of bias assessment version 2, and RevMan version 5.4.1 for data analysis were used.

Results:

Of 182 studies found through database search, five articles were included for systematic review and two for the meta-analysis, with a pooled sample size of 76 patients. A systematic review of five articles showed high risk in two articles and low risk in three articles. Meta-analysis showed no significant effect of yoga on cognition (standardized mean difference 0.17, 95% confidence interval: −0.28 to 0.63, P = 0.46).

Conclusion:

The results of the meta-analysis should be interpreted with caution owing to the low power, small sample size, methodological limitations in the included studies, and hence high likelihood of type II error. There is a need for more studies with rigorous methodology involving yoga for cognition in schizophrenia.

Hub-and-Spoke Model for Quality Improvement in Oncology Outcomes
Authors: Sinha Issac , Rapheal Jomon , Bishnoi Neeraj , Sharma Ankit , Pai Siddharth , Anand G , Choudhary Shovan
Published: November 2024

The hub-and-spoke model in oncology is a strategic approach designed to decentralize cancer care in India. In this model, a central, highly specialized cancer center (the “hub”) is connected to smaller, regional hospitals (the “spokes”). The hub provides advanced diagnostic and treatment facilities, while the spokes handle more common and less complex cases. This model aims to improve accessibility and quality of cancer care across the country. By distributing services, it reduces the burden on central hospitals and ensures that patients in remote areas receive timely and effective treatment. For instance, Tata Memorial Center has been a pioneer in implementing this model, proposing the development of 30–40 hub centers across India, each serving a population of 5–7 crores.

Published: November 2024

El objetivo general de esta investigación fue analizar los desafíos que generan las formas de ataque de la guerra no convencional a la ética militar frente a la defensa integral y la seguridad de la nación.  Se apoyó en el enfoque cuantitativo de tipo documental. Las operaciones militares contemporáneas exigen altos estándares al liderazgo de los oficiales; en consecuencia, deben ser conscientes de impacto que frente a situaciones difíciles tienen en otras personas; por lo que su conducta debe estar en línea con sus roles, normas y valores éticos, el comportamiento ético frente la guerra difusa y el dominio cibernético han ganado importancia en las discusiones teóricas y doctrinarias en el ámbito militar. La utilización de la fuerza militar debe estar dentro de los límites de la norma, pero sobre todo debe ser ética, lo cual es una de las razones principales por las que existe la ética militar. Sin embargo, no hay leyes que regulen los conflictos cibernéticos ni se enmarca en los conceptos de la teoría de guerra tradicional. Entre las conclusiones resaltan que los ataques cibernéticos dirigidos a la FANB podrían ser considerados delitos de guerra. Las armas de guerra cibernéticas son costosas y su efectividad disminuye rápidamente después de su uso debido a la pérdida de su elemento sorpresa, lo que las hace poco rentables.

La “epidemia de la esvástica” en Argentina
Authors: Kahan Emmanuel
Published: November 2024

El presente trabajo se propone abordar las características que tuvo la ola de antisemitismo en Argentina durante los años del “affaire Eichmann” (1960-´1962) y su impacto en una serie de ámbitos diferenciados: las intervenciones de las instituciones representativas de la vida judía en el país, la composición de grupos de autodefensa de jóvenes judíos y la movilización entre los estudiantes de colegios secundarios de la ciudad de Buenos Aires. Para ello, se analizarán una serie de documentos que aún no han sido relevados como el expediente sobre “la situación en los colegios secundarios” confeccionado por la Delegación de Asociaciones Israelitas de Argentina (DAIA) y un Legajo de la Dirección de Inteligencia de la Policía de la Provincia de Buenos Aires en torno a un procedimiento “contra elementos de la colectividad israelita”. Finalmente, se abordarán las representaciones simbólicas y culturales en torno al “caso Eichmann” y la ola antisemita que se circularon en Argentina en aquellos años.
Olho seco

Published: November 2024

O diagnóstico da doença de Sjögren (DSj) em pacientes com xeroftalmia envolve uma avaliação específica que inclui questionários para sintomas de olho seco, testes oculares, pesquisa de autoanticorpos e biópsia. Os desafios para a definição etiológica da doença do olho seco decorrem da sobreposição de sintomas clínicos com outras condições clínicas e do sub-referenciamento de pacientes para avaliação complementar de DSj. Não há um único teste que permita diferenciar o olho seco associado à DSj e somente a combinação de sintomas, exame ocular dirigido, autoanticorpos e biomarcadores séricos pode ajudar, a partir da avaliação abrangente de um oftalmologista experiente. O tratamento do olho seco em indivíduos com DSj é complexo e em evolução. Embora a terapêutica atual permita melhora de escores de ceratite, medidos pela coloração da córnea, e redução da inflamação da superfície ocular, é um desafio o desenvolvimento de tratamentos eficazes além dos colírios lubrificantes. Pesquisas futuras devem se concentrar em métodos de diagnóstico mais precisos e em estratégias terapêuticas personalizadas para melhorar a qualidade de vida dos portadores da doença e prevenção de complicações.

Published: November 2024

This study analyses the Indonesian sport announcers in relation to their repositioning as integral constituents of the game through the use of language and cultural content and embedding them in the cultural context of the country. The main purpose is to analyze how commentators create stories that are appealing to audiences, evoke emotions as well as build up nationalism. In this qualitative study, commentary data from different broadcasts of sporting events is examined, with specific attention to emotionality, cultural and syntactical elements of language. The research shows that Indonesian narrators utilize storytelling techniques to captivate their audiences. Other issues accentuated are the themes of national togetherness or oneness, hardwork and solidarity that tended to be pronounced in important matches and international games. Some words or these images of language socialise the audience and positively prepare them to their devotion to the sport and unite them toward the success of the sport. For example, sentiments concerning success at the national level and pride at having originated from a successful area not only highlight narrower success but also extend it to the broader society. This study advances both sports and sociolinguistics by elaborating about language, culture and sports events in the context of Indonesia. It shows the importance of sports commentary as a means of fostering cultural identity and social integration. The study also describes how the commentators create stories appealing to the viewers and opens the way for future investigation into the role played by media narratives in developing public opinion and community participation. In its outcomes, this research broadens the appreciation of the role of sports commentary in the entertainment and cultural industries and emphasizes the influence of language and culture on the audience experience.

El propósito de este estudio, fue investigar los efectos de dos tipos de entrenamiento de fuerza (RT), uno basado en la velocidad de desplazamiento de la carga (VBT), versus otro realizado al 70-80% de 1RM (PBT), sobre la masa muscular (MM), densidad mineral ósea (DMO), componente mineral óseo (CMO), activación neuromuscular (EMG), fuerza máxima en sentadilla (FSQ), salto vertical (VJ), potencia de pedaleo (PP) y velocidad de desplazamiento sobre 30 m (RV30). 31 mujeres se distribuyeron aleatoriamente en los dos grupos: VBT (n=16) o PBT (n=15), que entrenaron 3 veces por semana, durante 12 semanas. Antes y después del entrenamiento se determinaron los valores de FSQ, VJ, PP, RV30, BMD, BMC, MM y EMG. El grupo VBT entrenó a una velocidad propulsiva (VMP) de 0,68 ±0,08 m s − 1 y PBT entrenó a 70-80% de 1RM. El RT produjo aumentos significativos (p < 0,05) en los dos grupos en FSQ (VBT 33,79%, PBT 27,94%), VJ (VBT 19,11%, 8,77% PBT), RV30 (VBT 6,27%, PBT 1,66%), PP (VBT 32,2%, PBT 16,11%), MM sin grasa (VBT 3,7%, PBT 2,64%) CMO (VBT 0,39%, PBT 0,25%) y en DMO (VBT 0,76%, PBT 0,80%). No se observaron variaciones significativas en la actividad EMG en ninguno de los grupos. Se identificaron diferencias significativas entre los dos grupos de entrenamiento para DMO, PP, CMJ y RV30. En conclusión, el grupo VBT mostró mejores resultados que PBT con una menor carga de entrenamiento, lo cual es importante para un mejor seguimiento de la fatiga durante el entrenamiento de fuerza.

Integrating cognitive, affective, physical, and social aspects of learning helps introduce new ideas and consolidate existing thinking. Games and play can enhance reflective thinking skills in mathematics education. Games in mathematics teaching contribute to cognitive development and provide dynamic strategies for learning. Reflective thinking is one of the essential skills that mathematics students must possess. One method to foster reflective thinking is by applying outdoor contextual learning activities. This study aims to determine reflective thinking and the factors influencing through play and games-based contextual learning. This research method is descriptive and quantitative, with subjects of as many as 231 mathematics students determined based on a purposive sampling technique. The instrument used to collect data was the reflective thinking instrument developed by Kember. Data analysis was carried out using SEM modeling assisted by SmartPLS. Based on the data analysis results, it is known that understanding is the most influential indicator of reflective thinking, with a path coefficient value of 0.404 and a t-statistic > t-table of 19.430 > 1.653. Meanwhile, habitual action is the indicator with the lowest influence, with a path coefficient value of 0.129 and t-statistic > t-table of 3.818 > 1.653. In addition, critical reflection and reflection have a significant effect based on the path coefficient values of 0.330 and 0.381, respectively. This shows that the four indicators significantly influence the reflective thinking of mathematics teacher students.

This research is motivated by the increasingly complex environmental problems in Indonesia, such as deforestation, water and air pollution, ecosystem damage, and the significant impacts of climate change. The environmental crisis is not only caused by inappropriate policies, but also by the low public awareness of the importance of preserving nature. In this context, Islamic thought derived from the Qur'an is relevant to provide moral and practical solutions. This study examines the wisdom of two great Indonesian scholars, Buya Hamka and Quraish Shihab, through their tafsir works, Tafsir Al-Azhar and Tafsir Al-Misbah, which contain views on the relationship between humans and nature. This comparative study aims to identify the relevance of the interpretations of the two figures in answering contemporary environmental problems in Indonesia. Although there are differences in methodology in interpretation, both Buya Hamka and Quraish Shihab emphasize the importance of environmental ethics and human responsibility as caliphs on earth. In conclusion, their interpretations not only have theological value, but also provide relevant practical guidelines for addressing environmental challenges in Indonesia.

Portfolio assessments are increasingly popular in schools to assess student performance, achievement, and development. Portfolio assessments cover many aspects of a student's abilities and skills, allowing for a more thorough assessment than conventional evaluation methods such as written tests. It is hoped that it will improve the quality of education in Indonesia and encourage more meaningful learning. This study aims to evaluate how effective portfolio assessment is in improving the quality of learning and how it impacts students' motivation and academic achievement. In addition, this study also examines how portfolio assessment can be used well in the Indonesian education system. This study analyses the literature on portfolio assessment topics, including books, scientific journals, and research reports. The research includes a theoretical review of portfolio assessment, school implementation practices, and an analysis of the advantages and problems that arise when implementing them. Literature studies show that portfolio assessments can provide a more comprehensive picture of a student's abilities and development than conventional assessment methods. Portfolio assessments also encourage students to participate more actively in learning and improve their self-reflection skills. However, to implement portfolio assessments, teachers must be trained beforehand, and assessment rubrics must be well crafted. While portfolio assessments have great potential to improve the quality of education in Indonesia by providing more thorough evaluations and encouraging meaningful learning, the success of its implementation depends on the readiness of the education system, including adequate support from schools, teachers, and education policies. Therefore, further research is needed to develop a portfolio valuation model that is in line with these commitments.
