Native American Voices: Decolonial Perspectives on Selected Texts of Alexie and Momaday
Authors: Akram Dr. Sadia , Nazir Dr. Sadia , Akhter Saira
Published: January 2025

This paper explores the Native American voices through a decolonial reading of a range of selected texts of Sherman Alexie and Navarre S. Momaday. The aim is to understand indigenous culture as a prototype for retrieving the lost identity of American Indians. The decolonization of mind is realized through cultural resistance and counter-discourse that articulates the liminal experiences of the marginalized and the ostracized. Therefore, the literary representation of peripheral voices not only defies the dominant voice but also creates new avenues for cross-cultural communication with the mainstream discourse. This study employs the dialogic approach of Greg Sarris and Louis Owens as theoretical support for analysing the selected texts. The slippery frontier position of American Indians is not separatist but conversational that subverts stereotypes and, simultaneously, acknowledges difference. This essay principally explores how cross-reading Native American subversive texts can serve as a tool for cross-cultural communication. The indigenous writers with their lost identity (due to their living on reservations) write passionately about their past, traditions, and customs to make their voice heard in the mainstream discourse for their survival. This paper, therefore, proposes that the gap between Natives and Euro-Americans may be bridged through literary resistance for reconciliation instead of creating antagonism between them.

Published: January 2025

Background and purpose: Vascular dysfunction is the main key to cardiovascular, cerebrovascular, neurodegenerative diseases, and the aging process causes disruption of blood vessel function. Vascular Tortuosity (VT) and stenosis are types of blood vessel deformities resulting from vascular dysfunction. Both conditions can be diagnosed through cerebral Digital Subtraction Angiography (DSA) examination. This study aims to analyze the relationship between tortuosity and stenosis of extracranial internal carotid arteries and vertebral arteries on vascular risk factors at Pelni Hospital.
Methode: This research was a descriptive observational study with a cross-sectional approach on 608 subjects with a history of stroke who met the inclusion criteria. Conducted from January to September 2024, analyzing demographic data and risk factors, the presence or absence of stenosis and Vascular Tortuosity through cerebral DSA, also correlation these factors.
Result: From the 608 patients, 334 (54.9%) were male and 274 (45.1%) were female. Most of the subjects were aged 41-59 years (31.1%) with the most common risk factor being hypertension (76.6%). Carotid stenosis was significantly associated with age 51-59 years [odds ratio (OR): 2.452, 95% confidence interval (CI): 1.102-2.481, p=0.031)], female gender (OR): 1.665, 95% CI: 1.102-2.481, p=0.015; and hypertension (OR): 1.761, 95% CI: 1.099-2.821, p=0.019. Vertebral stenosis was significantly associated with female gender (OR): 2.160, 95% CI: 1.176-3.968, p=0.013; and diabetes (OR): 2.079, 95% CI: 1.015-4.255, p=0.045. Both stenosis conditions were significantly correlated with tortuosity conditions with OR: 2.320 for carotid, and OR: 12.090 for vertebral. Carotid tortuosity was significantly associated with diabetes (OR): 2.049, 95% CI: 1.051-4.000, p=0.035. Vertebral tortuosity was significantly associated with dyslipidemia (OR): 2.710, 95% CI: 1.099-6.711, p=0.030 and hypertension (OR): 2.079, 95% CI: 1.234-3.496, p=0.006. The combination of carotid stenosis and tortuosity was significantly associated with female gender (OR): 2.367, 95% CI: 1.378-4.066, p=0.002. The combination of stenosis and tortuosity in both arteries did not show a significant correlation with existing risk factors.
Conclusion: Carotid stenosis is correlated with female gender, age, and hypertension. Vertebral stenosis is correlated with female gender and diabetes. Carotid tortuosity is correlated with diabetes. Vertebral tortuosity correlates with dyslipidemia and hypertension. The combination of carotid stenosis and tortuosity correlates with female gender.

AVOGADO PEEL POLYPHENOLIC-FUNCTIONALIZED KERATIN-STARCH COMPOSITE: A NOVEL APPROACH TO EXTENDING SHELF LIFE AND ENHANCING POSTHARVEST QUALITY OF TOMATOES
Authors: Eidangbe G. O. , Oluba O. M
Published: January 2025

There is increasing research interest in the development of edible films and coatings that incorporate plant-derived antimicrobials to make perishable foods last longer and taste better. This study developed a bioactive keratin-starch composite (3:27 v/v) using varying concentrations (0.2–1.0 mL v/v) of polyphenolic extract of avocado peel. The keratin-starch composite was fabricated from 5% (w/v) keratin solution and 5% (w/v) starch solution. The functionalized keratin-starch composite was applied as a coating on light red-colored tomato fruits and stored at 25.0 ± 2.0 °C, 67.0 ± 2.0 relative humidity, and 12 h day and night cycle for nine days. Loss in weight, as well as changes in the physicochemical attributes (pH, titratable acidity, brix value, ascorbic acid and lycopene contents, and polyphenol oxidase activity), were analyzed on days 0, 3, 6, and 9 to ascertain the effects of the coating on the quality and shelf life of tomatoes. Tomatoes treated with avocado polyphenolic-extract enriched keratin-starch composite exhibited significantly lower weight loss, lycopene content, and polyphenol oxidase activity compared with uncoated tomatoes. Additionally, the treated fruits showed improved pH stability, elevated titratable acidity, and enhanced ascorbic acid retention, compared to those coated with the base keratin-starch composite for nine days. Overall, the tomatoes coated with keratin-starch composite functionalized with 1.0 mL avocado peel polyphenolic extract exhibited the best quality attributes after the 9-day storage period. These results underscore the potential of avocado peel polyphenols as a sustainable bioactive additive for biopolymer coatings, offering an eco-friendly approach to make fresh produce stay longer on the shelf while maintaining their nutritional quality
O VIGIA DE PEDRA: O teor testemunhal na poesia de Hérib Campos Cervera
Authors: Nogueira Sabryna Thais Silva
Published: January 2025

A literatura de testemunho/testimonio surge na América Latina nos anos 60 buscando reconstruir uma identidade nacional, dando voz às diversas vozes excluídas e silenciadas pelos projetos coloniais impostos pelo discurso hegemônico vigente. Nesse sentido, a obra do poeta paraguaio Hérib Campos Cervera aparece como um grande exemplo de literatura de testimonio, pois sua vida, suas lutas e seus exílios estão retratados em sua poesia; bem como o seu grande desejo de dar voz aos seus compatriotas que sofriam pela limitação de suas liberdades. Assim, buscamos apresentar neste artigo o forte teor testemunhal da obra de Cervera à luz da literatura de testimonio. Para esta análise, escolhemos dois poemas: Hachero e Un Puñado de Tierra.
O PENSAMENTO DE ANÍBAL QUIJANO E ENRIQUE DUSSEL: crítica à Modernidade como aporte decolonial
Authors: Dariva Bernard Guedes , Battestin Cláudia , De Lima Bruno Huffel
Published: January 2025

O presente artigo visa apresentar pontos argumentativos a respeito das teorias críticas à Modernidade em Aníbal Quijano e Enrique Dussel. Para isto, recorremos à pesquisa bibliográfica, na qual seus resultados apontam para uma convergência teórica entre os respectivos pensadores decoloniais. Em ambas as teorias críticas, se constatam elementos indicativos de que a Modernidade surge a partir da conquista da América e com a expansão e mundialização de um modelo padrão de sociedade. Tais resultados são possíveis por meio de relações violentas de poder e saber, na assimetria abissal entre conquistadores e conquistados. Como forma de superação dos processos hegemônicos de poder do projeto modernizador, os autores propõem o reconhecimento dos saberes silenciados, invisibilizados e excluídos, enquanto como possibilidades existenciais na constituição de identidades e subjetividades outras. Nesses movimentos de (re)existência, surgem os pressupostos dos pensamentos decolonial. Enquanto projeto teórico, político, ontológico e epistemológico, a decolonialidade transgride o campo teórico e busca nos saberes subalternizados novas possibilidades de transgressão à racionalidade moderna e suas violências ainda vigentes.
América Latina en la Geopolítica del Conocimiento. Una reflexión contra-hegemónica y decolonial
Authors: Estenssoro Fernando , Lorenzo Cristian
Published: January 2025

Este artículo plantea que el centro o Norte global ha ejercido históricamente una geopolítica del conocimiento del poder por medio de la cual ha logrado mantener su hegemonía intelectual sobre la periferia. En la actualidad esta hegemonía se manifiesta por el control de ránquines e índices de cientificidad de la producción científico-académica aceptados y asimilados en la periferia. De igual forma, se señala que existe una rica y diversa tradición latinoamericana de producción de pensamiento propio, invisibilizada por estos ránquines e índices del centro. Esta producción de conocimiento propio tiene en su situación geográfica un importante clivaje identitario. En este sentido, se puede hablar de una geopolítica del conocimiento latinoamericana contra-hegemónica
TEATRO NEGRO E ATITUDE: A DESCOLONIZAÇÃO DO CORPO EM PERFORMANCE
Authors: De Castro Siman Lana Mara , Contão Camila Cristian , Lana Débora Maria de Souza
Published: January 2025

O presente artigo tem como foco o Teatro Negro e Atitude (TNA), presente na cena teatral de Belo Horizonte, Minas Gerais desde 1993, cujas ações culturais vêm sendo construídas e realizadas ao longo dos últimos 28 anos, situadas no interior do Movimento Social Negro da cidade.  Buscou compreender e interpretar como, por meio do teatro, jovens negros se engajaram nas lutas de ressignificação de suas existências e da descolonização de seus corpos, marcados pelo projeto de colonização e decolonialidade dos negros em movimentos diaspóricos. Foram utilizados como instrumentos metodológicos entrevistas temáticas semi-dirigidas junto a integrantes do TNA, além da produção teatral do grupo e de referências bibliográficas atinentes ao tema.  Análises realizadas puderam evidenciar os trânsitos entre repertório e arquivo (Diana Taylor, 2013) e como através desse trânsito e, sobretudo da memória/incorporada presente no repertório, seus corpos negros em performance têm sido descolonizados. Além disso, pode-se perceber a força educativa deste movimento social e cultural negro, podendo motivar o engajamento de outros jovens negros no movimento teatral de Belo Horizonte, retirando da invisibilidade a presença dos negros na história de Venda Nova e produzindo outras referencias identitárias pela descolonização de seus corpos.Palavras-chave: Teatro Negro e Atitude. Movimento Negro. Corpo. Memória. Educação.

Authors: Raharjo Efendhi Prih , Kartika Komang Risma Devi , Adidana I Kadek Surya Putra
Published: January 2025

Gilimanuk Port is the gateway connecting Java and Bali. During the 2024 Eid holiday, traffic congestion extended 3.5 kilometers from the port entrance to the Denpasar-Gilimanuk Road, causing significant losses in fuel costs and travel time for travelers. This study aims to apply Transport Demand Management (TDM) strategies to roads near Gilimanuk Port during the Eid period to mitigate travel time losses due to congestion. The research utilized secondary data, including road maps and passenger numbers during Eid, along with primary data from road inventory surveys, public transport availability surveys, and pedestrian facility assessments. The analysis covered road performance, value-of-time calculations, and TDM implementation. The results showed that 53% of outbound vehicles from Bali were motorcycles, while inbound traffic was dominated by four-wheel vehicles and trucks. To address these issues, the study proposed several recommendations: establishing a buffer zone, building parking facilities, enhancing terminal accessibility, increasing ferry frequency, and improving vessel capacity. Of these recommendations, constructing parking facilities emerged as the most effective solution, reducing travel time losses by IDR 9,069,192 per hour in the study area. This suggests that strategically improving traffic flow and facility management can significantly alleviate congestion at Gilimanuk Port during peak travel seasons.
Do lugar que nos dança ao lugar que nos faz dançar
Authors: Vicente Gustavo
Published: January 2025

Tendo por base a experiência crítica da performance Nome de filme, de Bibi Dória, particularmente sobre duas das suas apresentações – no programa Interferências, em 2021, e no ciclo Cartografias, em 2023 –, este artigo começa por identificar a presença crescente de um conjunto de artistas migrantes cujo trabalho se tem manifestado de forma marginal ao encadeamento histórico da dança contemporânea em Portugal. Nesse sentido, desenvolvo a noção de geodança para me referir às forças canónicas que procuram estabelecer relações de causa-efeito entre as práticas artísticas e o legado sociocultural do território onde estas estão implantadas; reconhecendo, através do levantamento dos estudos existentes, os contornos específicos do panorama nacional.
É a partir deste confronto crítico que reforço a ideia do surgimento de uma prática nómada – para a definição da qual recorro ao pensamento de Rosi Braidotti – e que tem vindo a ocupar um espaço de contramemória e resistência aos processos de sedimentação epistemológica de uma possível genealogia da dança em Portugal. Neste contexto, abordo a relevância do posicionamento político em torno de questões emergentes e do carácter interdisciplinar das propostas apresentadas, sublinhando a necessidade de encarar a criação contemporânea a partir de uma perspetiva transversal ao estudo das artes performativas.
O olhar que conduz a minha escrita é o de um espectador implicado, designadamente sobre a performance de Bibi Dória, tentando, desse modo, situar o lugar a partir do qual avisto as coisas. Não só para poder oferecer-me enquanto correspondente desse mesmo movimento primordial da errância, mas também para deixar em aberto outras possibilidades de escuta e sensibilidades cognitivas sobre estas poéticas de emancipação territorial.
Addressing Legal Gap in Creditor Safeguards for Mortgage-Backed Loans
Authors: Andaryanti Yuni , Yuniarti Endang , Erawati Wahyu Ririn , Mashdurohatun Anis , Glaser Henning
Published: January 2025

This article studies the legal gap in creditor safeguards for mortgage-backed loans, focusing on substantive, structural, and cultural aspects of Indonesia’s legal system. Substantive challenges arise from gaps in the legislative framework, such as the rigid timelines stipulated in Law No. 4 of 1996 on Mortgage Rights, which often fail to account for practical delays in land registration processes. Structural gap, including inefficiencies in bureaucratic structures, limited capacity of the National Land Agency, and inconsistent oversight of Land Deed Officials, further hinder the implementation of creditor protections. These issues are compounded by cultural and normative barriers, such as the lack of legal awareness among debtors, permissive attitudes toward loan defaults, and societal acceptance of non-compliance with financial responsibilities. The article applies Lawrence M. Friedman’s theory of legal structures, highlighting the interplay between structure, substance, and culture, to analyse the factors contributing to these gaps. Recommendations include modernizing Indonesia’s land registration processes through reliable electronic structures, strengthening institutional capacity, enhancing oversight mechanisms, and fostering a culture of legal compliance among stakeholders. Additionally, promoting the use of authentic deeds in credit agreements and improving coordination between agencies are proposed as measures to reduce risks for creditors. The findings highlight the urgent need for comprehensive legal and institutional reforms to address these gaps, ensuring greater legal certainty and protection for creditors. By addressing these challenges, Indonesia can foster a more secure financial environment that supports economic growth while safeguarding the interests of creditors and other stakeholders in mortgage-backed transactions. This article contributes to the broader discourse on improving legal frameworks in emerging economies, particularly in the context of financial and property rights.

Authors: Lam Nguyen Que , Kien Nguyen The
Published: January 2025

This study provides a comprehensive analysis of consumer purchasing behavior during livestream sales on digital technology platforms, focusing on psychological and technological factors influencing buying decisions. Using Structural Equation Modeling (SEM), the research identifies key relationships between consumer attitudes, trust, perceived behavioral control, subjective norms, and purchase intentions. The findings reveal that consumer attitudes towards livestream sales positively impact purchase intentions, with perceived usefulness, ease of use, and perceived behavioral control contributing significantly to positive attitudes. Conversely, perceived risk does not significantly affect attitudes, indicating its limited role in livestream contexts. Consumer trust also positively affects purchase intentions, influenced by perceived risk, livestreamer reputation, and subjective norms. Purchase intention is a critical predictor of actual buying behavior. The study highlights practical implications for businesses and livestreamers, including improving livestream quality, enhancing user experience, and building consumer trust. Recommendations are provided for both businesses and consumers to optimize livestream sales strategies. The study also outlines limitations, such as the sample size and geographic focus, and suggests future research directions to broaden the understanding of livestream purchasing behavior.

Published: January 2025

Vibration analysis is commonly used to provide valuable insights into the condition of a machine, which is crucial for ensuring reliability and reducing maintenance costs. However, analysis of vibration signals using artificial neural network (ANN) is mostly via development of classification models, which cannot be suitably applied to several varied machine types and specifications. This study investigates the use of ANN in the clustering of vibration signals for machine condition monitoring of several rotating machines. Data obtained from different rotating machines for 4 years was utilized for the study. The data contained values of vibration signals taken at 12 different pickup points, power ratings, year and equipment location. The obtained data was preprocessed and analyzed statistically. Then, silhouette scores and within-cluster sum of squares (WCSS) were used to obtain the optimum number of clusters for the analysis. Afterwards, different clusters were created using ANN, which were then explored to gain insights for potential applicability of the technique for assessment of the conditions of rotating machines. The result of ANOVA showed that there were significant variations between readings obtained from different pickup points and readings obtained from the different machines, with p-values far less than 0.05 for both cases. It was found via silhouette and WCSS that 9 was an optimum number of clusters for the analysis. Calculated mean of standardized values informs that 6 clusters contained machines with different forms of faults, having positive mean values far greater than 0. Also, there were 2 clusters with machines having good working conditions with negative mean values, while one cluster had machines that were moderately okay with mean values close to 0. The study has shown that ANN can effectively cluster a set of machines based on their conditions using vibration signals taken at different pick-up points. The developed framework is a suitable alternative to ANN-based classification methods which have limited applicability.
Effect of Palm Kernel Shell Ash Supplement with Egg Shell Ash on Stabilized Lateritic Soil for a Road Work
Authors: Subair Sulaiman Olayinka
Published: January 2025

Lateritic soil serves as a fundamental material in road construction; however, its engineering properties can be significantly improved through the use of additives. In Nigeria, the abundant generation of agricultural by-products—such as palm kernel shells, eggshells, and wood residues—presents challenges related to waste disposal and management. These materials can contribute to environmental degradation, including air and water pollution, and adversely affect local ecosystems. This study explores the effects of Palm Kernel Shell Ash (PKSA) and Egg Shell Ash (ESA) on the stabilization of lateritic soil for use in road pavement applications. Comprehensive geotechnical testing was conducted on natural lateritic soil to assess various parameters: Specific Gravity (SG), percentage passing sieve No. 200 (F-200), Liquid Limit (LL), Plastic Limit (PL), Plasticity Index (PI), Maximum Dry Density (MDD), Optimum Moisture Content (OMC), and both unsoaked and soaked California Bearing Ratio (CBR). These parameters were also measured for stabilized soil samples incorporating 4% PKSA and varying percentages of ESA (0%, 2%, 4%, 6%, 8%, and 10%) by dry weight of the lateritic soil, in accordance with West African Standards (WAS). The analysis revealed that the natural lateritic soil exhibited an SG of 2.53, F-200 of 27.00%, LL of 29.00%, PL of 17.20%, PI of 11.8%, MDD of 1820 kg/m³, OMC of 11.5%, and CBR of 22%. Conversely, the stabilized samples demonstrated SG values ranging from 2.3 to 2.5, F-200 between 27% and 28%, LL from 27.0% to 30.0%, PL between 10.0% and 17.2%, PI ranging from 10.3% to 11.8%, MDD between 1860 and 2000 kg/m³, OMC values between 8% and 11%, and CBR results from 25% to 80%. Notably, the combination of 4% PKSA and 8% ESA resulted in significant improvements in the engineering properties of the soil, rendering it suitable for use as sub-base material in road construction. Therefore, this blend is recommended for effectively stabilizing lateritic soil for road infrastructure projects.
