Beyond Access: Factors Influencing Students' Utilization of Educational Technologies at Selected High Schools in Addis Ababa – A Survey Analysis
Authors: Yimmam Anteneh 
Published: December 2023

Relevant studies showed the positive influence educational technologies have on students' academic experience. This study examined how students in Addis Ababa's public, private, and international high schools use Educational Technologies to improve their academics. Thirty random schools were surveyed, and the collected data were analyzed using descriptive, regression, and inferential statistics to address the objectives of the study. The online survey had more than a thousand views per school, showing high accessibility of both the internet and devices. Most of the respondents used educational technologies. 18.4% of students who didn’t use edtech attributed it to a lack of guidance from their teachers. In Ethiopia and similar countries, many studies, including this one, found that teachers were not using educational technologies.
This study confirmed that using Edtech increased academic motivation. Interestingly, educational technologies were used equally irrespective of whether students found their daily lessons “applicable” or not. This contradicted other studies, which found that the use of e-learning in developing countries was significantly affected by their perceived utility. Similarly, there were only a few significant advantages or disadvantages of enrolling in any of the three high school categories. For instance, students learning in public schools showed a significant increase in social media use while international high school students got significantly better guidance on using edtech compared to their public counterparts.

Published: December 2023

A sustentabilidade como perspectiva socioambiental, apesar de ser amplamente discutida, na prática, ainda não atingiu as diversas realidades. A sua ampla implementação necessita da produção da pesquisa cientifica em todos os espaços. Este artigo demonstra a importância dessa modalidade de pesquisa, por meio do Programa de Bolsa de Iniciação Científica para alunos do Ensino Médio (BICEM), da Universidade Estadual de Montes Claros (Unimontes), na comunidade do Planalto Rural, localizada no município de Montes Claros/MG. O objetivo geral foi desenvolver uma prática científica com os estudantes, já os específicos foram: compreender a realidade socioprodutiva e as possíveis práticas sustentáveis da comunidade. O conjunto de procedimentos metodológicos levou em consideração a realidade das bolsistas, com o uso de técnicas quantitativas e qualitativas. Para alcançar tais objetivos, foram realizadas entrevistas e trabalhos de campo nos anos de 2018 e 2023, devido à pandemia. As informações e as reflexões foram apresentadas na escola, a fim de compartilhar o conhecimento com os demais alunos. Os resultados indicam que muitos produtores e seus filhos ainda não estão convencidos da relevância da sustentabilidade, prevalecendo ideias equivocadas e mitos. Destacou-se que a iniciação científica no Ensino Médio valoriza a compreensão da realidade sob o ponto de vista de quem nela vive.
La teoría decolonial: un análisis en perspectiva crítica
Authors: Herrera María Luz Mejias 
Published: December 2023

El presente trabajo tiene como objetivo abordar en una perspectiva crítica los postulados esenciales de la teoría decolonial, a partir de las consideraciones teóricas que, de forma general, aparecen en los enunciados de sus principales expositores. El tema reviste una actualidad y novedad teórica porque sus posicionamientos están insertados dentro de la tendencia de “pensamiento crítico latinoamericano”. Se utiliza una perspectiva lógica e histórica para explicar la direccionalidad de las concepciones generales que sustentan, en especial, el vínculo con la praxis y con las urgencias críticas que caracterizan al continente latinoamericano. Lo anterior se esboza desde el método de análisis cualitativo, lo cual permite explicar con una visión crítica los argumentos que sostiene la teoría decolonial para conformar un pensamiento genuino latinoamericano y superar las barreras de la “occidentalización” y los paradigmas europeizantes.

Caiçara é sujeito que vive em comunidade com modos de vida específicos, em meio ao bioma da Mata Atlântica, cria vínculos materiais e imateriais com o espaço ocupado, com o processo de territorialização. A desterritorialização dos indivíduos caiçaras ocorre com a migração, principalmente para as cidades, gerando novos movimentos de reterritorialização. Diante deste contexto buscou-se identificar no sujeito caiçara traços comuns presentes no processo de territorialização, desterritorialização e reterritorialização (TDR). A pesquisa foi construída por meio de revisão teórica e bibliográfica. Os resultados obtidos permitiram construir uma leitura dos traços comuns dos sujeitos caiçaras a partir do processo conceitual TDR, numa perspectiva individual de cada conceito.

Pandemi COVID-19 telah mengubah paradigma global terhadap kesehatan dan kebersihan lingkungan. Penyakit yang disebabkan oleh SARS CoV-2 telah menimbulkan dampak serius di seluruh dunia. Di Indonesia, penanganan pandemi ini melibatkan berbagai peraturan dan upaya pencegahan, termasuk penggunaan masker sebagai langkah penting. Selain karena pandemi tersebut penggunaan masker juga sangat penting dilakukan di area tertentu misalnya rumah sakit. Penggunaan masker oleh dokter dan perawat saat merawat pasien sangatlah krusial untuk melindungi mereka dan mencegah penyebaran droplet penyakit. Meskipun penting, tingkat kepatuhan terhadap penggunaan masker di rumah sakit masih bervariasi. Penelitian ini mengembangkan sistem deteksi masker pada wajah menggunakan metode convolutional neural network (CNN) arsitektur VGG16. Sistem deteksi masker ini dapat memberikan alternatif teknologi bagi petugas dalam mengawasi dan memantau penggunaan masker pada individu di lingkungan rumah sakit atau tempat-tempat lain yang memerlukan penggunaan masker sehingga membantu efisiensi pengecekan serta pengurangan beban kerja. Melalui pengujian dan evaluasi, ditemukan bahwa penggunaan threshold rendah sebesar 0.5 pada sistem deteksi masker memberikan hasil prediksi yang lebih akurat dengan tingkat akurasi mencapai 90% dan f1-score 0,909. Pengaturan threshold ini memungkinkan sistem menjadi lebih sensitif dalam mengenali apakah seseorang menggunakan masker atau tidak.
Wykonywanie zadań publicznych jako determinanta podmiotowych granic publicznego prawa podmiotowego dostępu do informacji publicznej

The study concerns the subjective limits of the public subjective right to public information. It attempts to answer the question of the addressee of the claim characterizing this right in the Polish legal order from the perspective of constitutional regulations and the provisions of the Act on Access to Public Information. The analysis focuses on the interpretation of the statutory concepts of “public tasks” and “entity performing public tasks” using the method of doctrinal interpretation as necessary in this respect. At the same time, such an understanding of doctrinal interpretation was adopted, according to which it is an interpretation carried out in the process of implementing the law, i.e. in specific circumstances, by the entity implementing this law and made from the point of view of the science of law, i.e. when referring to scientific arguments in the justification of the position and proposed solutions presented. For this reason, the results of the doctrinal interpretation of the terms “public task” and “entity performing public tasks” were also referred to the views presented in the jurisprudence of administrative courts. The analysis led to the conclusion that an “entity performing public tasks” within the meaning of the Act on Access to Public Information can be spoken of when the obligation to act of a specific entity corresponding to the content of the public task is anchored in a legal norm addressed to this entity, and the responsibility for its implementation is borne by the public-law community (state, self-government communities), of which this entity becomes a body in the functional sense. At the same time, this analysis justifies the conclusion that the theoretical constructions of administrative law, apart from their obvious scientific value, also have operational significance, and the need or even necessity to use the method of doctrinal interpretation in the area of this law seems obvious.
Archaeological observations on agro-pastoralist integration in south-central Inner Mongolia during the Eastern Zhou
Authors: Cao Jian’en 
Published: December 2023

Abstract
This paper archaeologically investigates three representative Eastern Zhou cemeteries in south-central Inner Mongolia. Through analysis, two types of tombs can be distinguished, according to the forms of tombs and assemblages of grave goods. Type A tombs belong to Zhao state agricultural immigrants from the south; Type B, pastoralists from the north. The coexistence of two groups of people with distinct subsistence economies in one cemetery reflects the integration process of agriculturalists and pastoralists. The emergence of agro-pastoralist integration in central-southern Inner Mongolia cross-confirms historical trajectory of the southward advance of pastoralists and the strategic management of northwestern areas by the Zhao state.
Further discussion on the origins of horse stirrups
Authors: Li Yunhe 
Published: December 2023

Abstract
This study re-examines the origins of stirrups and related issues by reassessing two prevailing theories: the “leather toe loop theory” and the “toe stirrup theory.” Through analysis of original archaeological material from the Scythian, Indian, and the Yunnan Dian cultures, along with new insights from fieldwork and examination of a variety of horse tack, this study points out that both outdated theories misinterpret the original material and present unreliable arguments. Consequently, it is unconvincing to claim that stirrups originated from either leather toe loops or toe stirrups. The improvement of saddle structure should not be ignored in an exploration of the origin of stirrups. The solid-tread saddle, which first appeared during the Wei and Jin periods, not only stimulated the invention of the stirrup but also provided necessary structural support for its use.
Fast and facile pH tailored green synthesized ZnO photocatalyst by biogenic reduction using water extract of Averrhoa bilimbi (L) fruit
Authors: Ramanarayanan Rajita , Swaminathan Sindhu , Meethal Bhabhina Ninnora 
Published: December 2023

Abstract
The present study reports an economical and environmentally friendly technique for the synthesis of zinc oxide nanoparticles. The water extract of Averrhoa bilimbi (L) fruit was used in this one-pot synthesis approach for ZnO nanoparticle reduction and stabilisation. Varied size, shape and properties of the synthesized nanomaterials were obtained by tuning the pH of the synthesis medium. X-ray diffraction techniques, diffuse reflectance spectroscopy, photoluminescence and scanning electron microscopy analysis were used for characterizing phytochemical capped ZnO nanoparticles. The morphological change with varying pH was observed from scanning electron microscopy images. Short duration of synthesis with high yield product at ambient room temperature are the salient features of this procedure. The synthesised ZnO nanoparticles showed excellent photocatalytic activity and superhydrophilicity to be used in a wide range of applications.
Seriality and Individualization: Carving the Fluted Sarcophagi from Hierapolis of Phrygia
Authors: Anguissola Anna 
Published: December 2023

Abstract
Several marble sarcophagi, including both plain or fluted coffins and chests decorated with garlands, friezes, and elaborate compositions framed by columns and covered with roof-shaped or kline lids, are attested in the Roman burial grounds at Hierapolis in Phrygia (Turkey). Because of their repetitive, standardized pattern, fluted sarcophagi have been dismissed by scholars as the formulaic, more affordable output of local workshops. Contrary to the apparent simplicity, however, each item is highly individual with respect to the morphology of its mouldings and flutes, surface treatment, and decorative details. The majority of the pieces from the North Necropolis seem to have been carved in response to individual requirements. While rationalized modes of production likely dominated the economic landscape of the Roman sarcophagus industry, customers could exercise a significant degree of control over the pieces carved by local quarry-based workshops. Exploration of these processes, operational flows, and histories may yield new perspectives on the social and economic relationships that underpinned the production and trade of Roman sarcophagi.
Preparation of PVDF-HFP/CB/Ni nanocomposite films for piezoelectric energy harvesting
Authors: Wang Yang , Lei Dan , Wu Liangke , Hu Ning , Ning Huiming , Alamusi  , Liu Yaolu 
Published: December 2023

Abstract
As a representative flexible piezoelectric polymer, polyvinylidene fluoride (PVDF) and its copolymers have been widely used in energy harvesters and piezoelectric sensors. In this work, hybrid nanocomposite films were prepared by adding a small amount of carbon black (CB) and Ni nanoparticles to the poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) matrix using the solution casting method, followed by stretching and poling to increase the electroactive β-phase content. The results show that the hybrid fillers consisting of 0.3 wt% CB and 0.1 wt% Ni nanoparticles exhibit the best piezoelectric performance. The maximum output voltage of the PVDF-HFP/CB/Ni films reaches 3.5 V under 1 mm micro-vibration, which is 75% higher than that of pure PVDF-HFP films. Characterization results by X-ray diffraction analysis, Fourier-transform infrared spectrometry, and differential scanning calorimeter analysis show that the hybrid fillers are more effective in promoting the phase transformation from the α-phase to the β-phase in the matrix due to synergistic effect.
Quantum mechanical investigation of the mechanism of Ni(0)-catalyzed cycloaddition reaction of 2-cyclobutanone with alkyne

Published: December 2023

Abstract
The mechanism of the Ni(0)-catalyzed cycloaddition reaction of 2-cyclobutanone with alkyne was studied using the function M06-2X with two basis sets. The computational results indicate that the reaction occurs through two independent pathways, one of which is related to the coordinating of C=O bond of oxidative addition of 2-cyclobutanone to the Ni(0) center (pathway 1), and the other involves coordination of C(sp3)–H bond (pathway 2) to form an intermediate containing either a Ni–C(O) or Ni–C (sp3) bond, then insertion an alkyne into either Ni–C(O) or Ni–C(sp3) bond. In the last step, the products are formed and the catalyst is regenerated through the reductive elimination. Our computational results are consistent with previous computational studies for cycloaddition of 3-azetidinone to alkyne except that the mechanism takes place through two independent pathways, i.e. there are no transition states or intermediates involved in the two pathways, which is contrary to what it has been indicated in previous studies. In addition, our results show that the Ni-catalyzed cycloaddition reaction of the 3-azetidinone with the alkyne is more active compared to the 2-cyclobutanone by free energy of 10.4 and 9.3 kcal/mol according to pathway 1 (7.4 and 8.1 kcal/mol according to pathway 2) calculated by the M06-2X(I) and M06-2X(II) methods, respectively. An analysis of the electrophilic and nucleophilic indices of the reactants was carried out.
Thirty years of research in tropical medicine: historical trends for the world and for the Revista de Biología Tropical (1990-2020)
Authors: Monge-Nájera Julián , Ho Yuh-Shan 
Published: December 2023

Introduction: The importance of tropical medicine cannot be overstated, since by the end of the 2030s, most humans will live in the tropics and will need protection from tropical diseases. Nevertheless, until now, there are no bibliometric studies about tropical medicine as a whole; all previous studies are limited to diseases, countries or particular journals, and are often limited to brief periods of time. Here we present an analysis of historical trends for the world and for the Revista de Biología Tropical in celebration of the journal’s 70th anniversary.
Objective: To assess geographic and historical trends in the study of tropical medicine included in a general database, the Web of Science and from a detailed analysis of one journal of particular importance for the field in the neotropical region.
Methods: We limited our data to journals covered by the Web of Science category “tropical medicine” in the Science Citation Index Expanded (data updated 19 January 2022) and the Journal Citation Report on 30 June 2021.
Results: We retrieved 69 480 articles, of which 44 % resulted from international collaboration with 194 participating countries; articles may reach 17–21 citations each, and the countries with outstanding results in the database include USA, Brazil, UK, Kenya and Switzerland. Research focus changes as diseases such as HIV, Dengue and tuberculosis become more or less important over time, but overall there was much research on Plasmodium, leishmaniasis and schistosomiasis. The journal Revista de Biología Tropical has significantly increased the number of topics covered, but still publishes studies about tropical biomedical subjects.
Conclusions: While countries with large research budgets have a large presence in this database, lower income tropical countries like Brazil and Kenya have done a remarkable contribution in the field of tropical medicine. The Revista de Biología Tropical has been publishing quality research about tropical medicine for the last seven decades.
