Authors: Priatmoko Sigit , Santoso Anang , Dewi Radeni Sukma Indra , Sugiri Wiku Aji
Published: August 2024

The Indonesian government continues improving teachers’ readiness to implement the Kurikulum Merdeka. Teacher readiness plays an important role in supporting the implementation of the Kurikulum Merdeka. This study aims to examine teachers’ readiness to implement the Kurikulum Merdeka. This study used a descriptive quantitative approach. Data was mainly collected by distributing online questionnaires through the Whatsapp chat application. The questionnaire was used to collect data on teacher readiness in (1) understanding of The Kurikulum Merdeka policies, (2) understanding of curriculum structure, (3) understanding of the Pancasila Student Profile Strengthening Project (P5), (4) readiness to develop lesson plans, (5) readiness to deliver instruction, and (6) readiness to conduct instructional assessments. Forty Madrasah Ibtidaiyah (MI) teachers were involved as respondents. They were in-service teachers who were students of the Teacher Professional Education Study Program (PPG). They came from the provinces of East Java, South Sulawesi, West Nusa Tenggara, Southeast Sulawesi, West Java, South Kalimantan, East Nusa Tenggara, and Bali. The data were analyzed using the quantitative descriptive method. The results showed that measuring the six key aspects of the Kurikulum Merdeka showed that teacher readiness was in the high category. However, some respondents still get a medium score in learning and assessment. So, the research respondents are sufficiently ready to implement the Kurikulum Merdeka but still need to improve their readiness for learning and assessment.

Published: August 2024

The overexposure to ultraviolet (UV) radiation from sunlight is related to photoaging of the skin and high risk of skin cancer. Sunscreen material and antioxidants are commonly used to protect skin from harmful UV. However, the application of synthetic compounds in sunscreen products is regulated to a limited amount because it can produce photosensitizers, inducing adverse reactions in the skin, and also harmful to the environment. Ethanol extract of Phyllanthus urinaria L. herb possesses a strong antioxidant activity similar to ascorbic acid, which makes it potential to substitute the synthetic compound in sunscreen products. Therefore, this research was conducted on the 70% ethanol extract of P. urinaria herb to analyze its in vitro anti-photoaging properties, i.e., antioxidant, protein antiglycation and antiinflammation, also to determine the Sun Protection Factor (SPF) and the quantitative composition of the metabolites. The extract exhibited a strong antioxidant activity IC50 of 3.01 mg/L, a higher moderate antiglycation activity IC50 of 216.67 mg/L, but low anti-inflammatory activity IC50 of 86.61mg/L. The presence of saponin, phenolic compounds, flavonoids, tannins, and methyl linoleates is suggested to contribute to the anti-photoaging properties. According to the anti-inflammatory assay, the extract may not inhibit signaling pathways that follow cytokine expression but possibly inhibit those that precede cytokine expression due to its antioxidant activity. An SPF value of 5.95 at 50 mg/L meets the recommended range for the skin phototypes of Southeast Asian, dark-skinned Asian, and African people. These results indicate that P. urinaria extract has potential as an anti-photoaging material for sunscreen products.Keywords: antiglycation, antiinflammation, antioxidation, Phyllanthus urinaria L., SPF.

The Paradox of Humanitarian Recognition
Authors: Berhane Fiori
Published: August 2024

Eritreans experience what I call the paradox of humanitarian recognition. Beneficiaries of some of the highest refugee-recognition rates in Global North countries, Eritreans nevertheless experience kidnap, ransoming, extortion, and pre-emptive detention in countries of transit like Sudan and Libya. Efforts by the European Union to address these abuses under multilateral anti-trafficking agreements—as well as broader efforts to externalize European borders and asylum—have further contained and criminalized networks of solidarity that extend beyond countries of transit into countries of settlement such as Italy. Based on twenty months of participant observation and interviews with Eritreans in northern Italy, this article analyzes Eritrean migrants’ experiences of violence in Libya, a country of transit, and efforts of Eritrean activists to both bring this violence to light and to aid recent refugees. Eritreans’ experiences of seeking asylum upend the binaries between legal inclusion and exclusion on which refugee exceptionalism is predicated.
Effective Cynicism
Authors: Plueckhahn Rebekah
Published: August 2024

In this article, I show how “effective cynicism” allows residents to decipher unequal power relations in Ulaanbaatar, Mongolia. Ethnographic analysis of the myriad ways residents hold onto dilapidated housing in a failed redevelopment scheme reveals how residents’ cynical reflections assist in their efforts to decipher and mobilize state authority. Residents undertake this while simultaneously negotiating the insidious decay of waste accumulated as a by-product of failed redevelopment processes. Throughout, I focus on the presence of waste and cynicism as phenomena that both foreclose and open possibilities. I argue that residents’ repurposing of cynicism as a diagnostic tool, rather than producing detachment, presents a reframing of Peter Sloterdijk’s (1987) discussions of cynical realism, where such realism holds generative potential. Considering the lived experience of urban decay through the three-pronged analytical framework of cynicism, power, and waste reveals subtle residential reconfigurations emerging within the materialities of for-profit redevelopment.

Media and policy legitimacy: A study of news coverage of the Flemish Human Rights Institute
Authors: Steeman Lise-Lore , d’Haenens Leen , Fobé Ellen
Published: August 2024

European countries are required to establish equality bodies to combat discrimination. For the success of such bodies, informing citizens about their existence and functioning is essential. Therefore, this study conducts a thematic content analysis of news coverage (N = 129 Flemish news articles) pertaining to the recently established Flemish Human Rights Institute (FHRI) in Belgium. The analysis focuses on the subjects addressed in the news articles, the individuals or groups involved, and the interpretation of the three components of the responsiveness triangle (policy system, social perspectives, and policy environment), which collectively determine the perception of a legitimate policy. The study’s findings reveal that the articles extensively feature varying viewpoints from politicians and civil society organizations regarding the FHRI’s policy system, including its competences, institutional formation, and operation, as well as its role in protecting citizens’ rights. However, the news articles refrain from offering a conclusive assessment of the institution’s legitimacy.
Optimization strategies for graphene-based protection coatings: a review
Authors: Han Qing , Wang Rongnan , Xue Yunzhou , Camilli Luca , Yu Gui , Luo Birong
Published: August 2024

Graphene has become an emerging and promising option in the field of protection coating for anti-corrosion due to its specific properties in chemical inertia and physical impermeability. It can be applied to metal protection coating in forms of either atomically thin films or composite materials, known, respectively, as pure chemical vapour deposition (CVD) graphene coatings and graphene composite coatings (GCCs). Nonetheless, various structure defects, synthesis imperfections and graphene’s positive potential to metals would make graphene-based protective coatings tend to exhibit corrosion promotion by arousing micro-galvanic corrosion, largely undermining its anti-corrosion efficiency. Based on this, many optimization strategies and methods have been conceived and applied to the graphene-based protection coatings in these two aspects for improving its anti-corrosion efficiency. For example, a good dispersion and orderly arrangement of graphene derivatives in the GCCs can largely optimize its anti-corrosion performance. Here, this paper separately reviews detailed optimization strategies, corresponding mechanisms and key factors for the use of representative graphene-based materials in these two aspects, with the aim of providing comprehensive knowledge and a roadmap of developing cheap, powerful and effective barrier technologies. Finally, perspectives on opportunities and challenges in improving the barrier coating efficiency of graphene-based materials are discussed.

Published: August 2024

This article explores the dynamics of nanofluids consisting of copper (TiO2) nanoparticles suspended in water, as they interact with sensor surfaces between two parallel squeezing plates with porous characteristics. This research specifically targets applications involving enhanced heat transfer and magnetohydrodynamic (MHD) control in nanofluid systems. The primary aim is to analyze the effects of nanoparticle aggregation and non-aggregation on sensor surfaces, considering MHD formations and heat transfer in the energy and momentum equations. The research adopts a steady-state fluid condition and utilizes similarity transformations to convert partial differential equations into more manageable ordinary differential equations. The methodology involves shooting methods for solving these nonlinear ordinary differential equations and employs graphical analyses to study the impacts of various parameters such as permeability, magnetic influence, squeeze flow, and radiation on the temperature and velocity profiles of the nanofluid. The results reveal significant dependencies of temperature and velocity profiles on the studied parameters, illustrating varied behaviors in scenarios of both aggregation and non-aggregation of nanoparticles. The findings emphasize how each parameter distinctively influences the heat and flow characteristics of the nanofluid, offering insights into optimizing conditions for better performance and control in practical applications. Future research could focus on extending the model to include transient fluid states and exploring the effects of other nanoparticle materials and shapes. There is also potential to investigate the interactions under different environmental conditions and to incorporate more complex boundary conditions to simulate real-world applications more accurately. Further experimental validation of the theoretical predictions would be beneficial to enhance the reliability and applicability of the findings.

Using rice husk ash (RHA) as a cement substitute in concrete production has potential benefits, including cement consumption and mitigating environmental effects. The feasibility of RHA on concrete strength was investigated in this research by predicting the split tensile strength (SPT) and flexural strength (FS) of RHA concrete (RHAC). The study used machine learning (ML) methods such as ensemble stacking and gene expression programming (GEP). The stacking model was improved using base learner configurations ML models, such as, random forest (RF), support vector regression, and gradient boosting regression. The proposed models were validated by statistical tests and external validation criteria. Moreover, the effect of input parameters was investigated using Shapley adaptive exPlanations (SHAP) for RF and parametric analysis for GEP-based models. The analysis revealed that the stacking ensemble integrates base learner predictions and demonstrated superior performance, with R values greater than 0.98 and 0.96. Mean absolute error and root mean square error values for both SPT and FS were 0.23, 0.3, 0.5, and 0.7 MPA, respectively. The SHAP analysis demonstrated water, cement, superplasticizer, and age as influential parameters for the RHAC strength. Furthermore, the SPT and FS of RHAC can be predicted with an acceptable error using the GEP expressions in the standard design procedure.
APROXIMAÇÕES ENTRE SURREALISMO E PSICANÁLISE A PARTIR DE AS MAMAS DE TIRÉSIAS, DE APOLLINAIRE
Authors: Freitas Moraes Maria Eduarda
Published: August 2024

Este trabalho propõe a discussão da obra As Mamas de Tirésias (1917/1985), de Apollinaire (1880-1918), a partir da psicanálise lacaniana. Sugere-se a aproximação entre o termo “ato analítico”, desenvolvido por Jacques Lacan no seu seminário XV, e o movimento artístico que ficou conhecido como surrealismo, tendo Guillaume Apollinaire como um de seus precursores. Salienta-se que tanto a surpresa, quanto o que aparentemente emerge como “sem sentido” na peça de Apollinaire buscam provocar efeitos no público e, nessa via, entende-se a aproximação com o ato analítico como passagem da experiência humana que atravessa o corpo. A linguagem torna-se complexa: parte do princípio de que há uma dimensão dialogicamente transmissível do vivido; no entanto, há também uma dimensão indizível da experiência, que requer o imprevisto para irromper de modo a questionar a linguagem puramente verbal. Conclui-se enfatizando a arte e, sobretudo, o drama, como ferramentas para a elaboração discursiva das experiências que atravessam o sujeito para além do verbal.

UMA BRUXA NA IGREJA: A IRONIA ENQUANTO TURVADORA DO SAGRADO E DO PROFANO EM GRAÇA INFINITA
Authors: Kurowsky Kleber
Published: August 2024

O propósito deste artigo é observar os usos da ironia no romance Graça infinita doautor norte americano David Foster Wallace a partir do conceito de profanação conformeproposto pelo filósofo Giorgio Agamben. É uma pesquisa que surge a partir da demandasempre frequente de explorar e compreender a ironia na obra ficcional de Wallace , algo que sedeve à presença declarada deste tema em obras ficcionais como Graça infinita e obras ensaísticascomo “E Unibus Pluram”. Em Graça infinita , especificamente, a ironia parece ser criticada, emuma leitura inicial, pela sua proximidade aos mecan ismos de funcionalidade do capitalismo e,portanto, se abre para abordagens que empreguem teóricos que nos ajudem a compreendercomo isso se dá. Pensando em como Wallace retrata a realidade capitalista em seu romance, ecomo Agamben compreende e estuda ess a realidade, realizaremos uma leitura de Graça infinitaque tem o ensaio de Agamben “Elogio da profanação” 2007 como principal eixo teórico,buscando observar, principalmente nos entornos da ironia, como podemos observar a ideia deprofanação no romance de Wallace.

Authors: Cristina Caldas Raimunda , Edviges Albuquerque Francisco
Published: August 2024

A presente discussão considera a interpretação no ensino bilíngue nas escolas indígenas dos Ka'apor, povo que fala a língua Ka'apor do sub-ramo VIII da Família Tupí-Guaraní (RODRIGUES, 1986), na área indígena Alto Turiaçu no Maranhão, e dos Apinayé, habitantes do norte do Estado do Tocantins, povo indígena remanescente dos Timbira, cuja língua é pertencente ao Tronco Linguístico Macro-Jê e à Família Linguística Jê (RODRIGUES, 2002, p. 18). O estudo nessas duas comunidades indígenas brasileiras considera, de um lado, no que respeita ao exercício de transitar conceitos entre línguas minoritárias – as indígenas –, com forte uso oral em suas práticas sociais e, de outro, uma língua de prestígio – o português –, de tradição escrita, em contexto de educação bilíngue. As reflexões baseiam-se na tradução textual de Hurtado Albir (2001) e abrangem as análises sobre a tradução de base filosófica em Ricoeur (1996), as relações de bilinguismo (GROSJEAN, 2010) e de interculturalidade (MATO, 2008).

Published: August 2024

In this study, it was aimed to examine the effects of pilates exercises applied to university students for 8 weeks on physical activity and sleep quality scores. Forty students (20 female, 20 male) studying at Nevşehir Hacı Bektaş Veli University voluntarily participated in the study. Individuals participating in the study were administered the International Physical Activity Assessment Questionnaire (IPAQ); short form and the Pittsburgh Sleep Quality Index (PSQI) as well as personal information forms including demographic variables. Then, the experimental group practiced Pilates exercises for 8 weeks, 2 days a week, 60 minutes a day, and the training and measurement process was completed by retaking the information obtained as pre-tests through the forms. In the analysis of the data, the normality test was evaluated with Kolmogorov Smirnov and Shapiro-Wilks tests, and Pearson correlation analysis was used for the relationships between variables with normal distribution. Independent Sample T Test was used to compare variables. Confidence interval was 95% and values below p<0.05 were considered significant. According to the analysis results of the participants, it was determined that there were significant differences in favor of the experimental group in the Sleep Quality score (p=,041), Physical Activity total (p=,000) score and physical activity sub-dimensions (High, Medium, Walking) scores of 8-week pilates practices applied to university students. In addition, there was a moderate (r=637) positive correlation between total physical activity score and physical activity sub-dimensions. As a result, regular pilates exercises provided statistically significant differences in sleep quality, physical activity total score and physical activity sub-dimensions and increased the daily physical activity level in participants with a sports background. In the light of these results, we can recommend pilates exercises to increase physical activity level and sleep quality.
Influencia de las emociones sobre la confianza institucional
Authors: Torralba Barreto Daniel Ricardo , Correa Zabala Mónica María
Published: August 2024

This document examines the relationship between the collective emotions expressed by young people in Colombia at various times and their trust in the country’s institutions. An aggregated measure of institutional trust is constructed using the Multiple Correspondence Analysis technique. Subsequently, the relationship and impact of emotions on institutional trust are estimated through the fitting of a model adjusted to the Generalized Beta Type 1 density function. The emotions that generate the most social mobilization are anger, sadness, and surprise, with the latter having differential effects depending on age and levels of institutional trust. No differences in perceptions towards institutions were found based on the gender of the respondents. Issues are dynamic and may vary according to predominant emotions. Contrary to expectations, joy does not have a positive effect on institutional trust. Additionally, there is no evidence of emotional cascades, despite dynamic changes in collective emotions during each conjunctural process.

Published: August 2024

In developed nations, there's a growing concern for sustainable energy management, particularly regarding enhancing energy efficiency in both existing and new buildings. The methodology presented considers the energy modelling and simulation of manufacturing buildings through thermal and electrical loads calculations using Dymola/Modelica software. The thermal model is built with the primary components of Dymola along with available models to calculate the heating and cooling loads, whereas the electrical model was calculated using consumption patterns, then the total model was validated against real measurements where the error percentage was 9.96 %. The yearly heating load baseline was 6295 kWh/y and for cooling 46276 kWh/y., the exciting potential for energy- savings and load flexibility, and some suggestions for improving consumption were pointed out and identified. It found that the highest influence on the thermal load reduction was using the double glaze with shading with 61% of the energy-saving options, then replacing the fluorescent with LED with 30%, and finally, the roof insulation was the least influence with 9.5%. For the total consumption, the highest percentage was for replacing the fluorescent with LED with 78% of energy-saving options, then double glaze with shading, and finally the lowest is for the roof insulation.
