Reviewing the ambiguity in the socio-economic outcomes of large-scale tree plantation investments: reconciling decades of contrasting evidence from sub-Saharan Africa
Authors: Kainyande A. , Hintz K.S. , Kyamagero S. , Auch E. , Giessen L.
Published: December 2024

Large-scale tree plantation investments are crucial for socio-economic development in rural sub-Saharan Africa (SSA). Yet, the negative consequences of this plantation development model have been flagged because insights regarding their socio-economic impacts, especially in the context
of SSA, remain fragmented and nuanced in the literature, marked by both positive and negative outcomes. Therefore, following a narrative review of empirical and non-empirical studies, we aim to synthesize existing evidence to enhance the conceptual understanding of the socio-economic outcomes
arising from these investments. By reference to regional and country-level case studies, we analyzed outcomes in three key dimensions: infrastructure and rural development, employment generation and livelihoods, and land use dynamics and rural land governance. Sustainable forest management
is identified as pivotal for empowering local communities. Practical implications for improving community relations within the plantation industry are provided. Leveraging these investments can aid in forest landscape restoration that balances social, ecological and economic needs.

Educational technology has altered conceptions of effective learning. The combination of virtual and physical instruction is constantly developing and growing, making blended learning a growing trend. While blended learning has been extensively reviewed in various fields, there is a lack of research on its application in music education. This study aims to understand the current development of blended learning in the field of music education; this paper will collect literature on blended learning from the past ten years. Following the PRISMA guidelines, we have systematically analysed the blended learning strategies and outcomes in music education. This study examined Web of Science, Scopus, and ERIC for pertinent strings. Thirteen publications passed the strict screening procedure and were included in the analysis of blended learning in music education. This study found that the flipped classroom blended learning model has emerged as the prevailing method in music education, enhancing learners’ musical perception, performance, and overall experience. The findings reveal a need for more research on blended learning in music education.
Listening to Sad Music: a Narrative Review
Authors: Ny Cheah Pei , Wing Cheong Ku
Published: December 2024

As noted in the tragedy paradox, the enjoyment of negative emotions evoked in artworks is a phenomenon acknowledged from ancient times to the present. Sad music listening induces a diverse range of emotional responses in the listener: some would experience pleasure, while others find it unpleasant; hence, this review aims to categorise sad music listening from the philosophical, psychological, sociological, and scientific perspectives. This review includes studies of journal articles, review articles, books, and book chapters from 2010-2022. The philosophical perspective reviewed the paradox of the attraction towards sad music. The psychological perspective reviewed the empirical studies that examined various factors contributing to enjoying sad music. The sociological perspective reviewed how sad music can be used to create a social connection. The scientific perspective reviewed the biological effects of sad music listening. Many of the studies found are related to the psychological perspective, in which sad music can induce diverse emotions, and there are several factors that contribute to the enjoyment of sad music. As more scientific research has been emerging in recent years, future research can explore the brain correlates and hormonal stimulation in various individual differences to consolidate why some people enjoy sad music while others do not.
Development of a Conghua Cat Head Lion Dance Animation as a Catalyst for Intangible Cultural Heritage Preservation
Authors: Fei Deng , Wong Shaw-Chiang
Published: December 2024

Conghua Cat Head Lion Dance (CHLD) is a traditional dance art that faces challenges in inheritance and education. Animation is engaging and emotionally resonant, naturally appealing to the younger generation, making it a tool that scholars recommend for the preservation of intangible cultural heritage (ICH). This study employs animation as a catalyst to promote and preserve the art of CHLD among the younger Chinese generation by raising their awareness of it. This study was divided into three stages. In the first stage, a field investigation was conducted at the ancestral hall in Guangdong Province, China. Additionally, semi-structured interviews were held with four purposively selected inheritors to collect qualitative data. The application of thematic analysis revealed four distinctive elements that could be incorporated into the animation: (1) characters, (2) patterns and costumes, (3) props, and (4) performance techniques. In the second stage, an animation was created by incorporating CHLD elements, following The Cognitive Theory of Multimedia Learning (Mayer & Moreno, 1999) and The Animation and Design Principles for Instructional Animation (Betrancourt, 2005). In the third stage, a self-administered survey questionnaire was used to examine whether the CHLD animation had the potential to increase the awareness of CHLD culture preservation among a randomly selected group of 181 students from Guangzhou City Construction College and Guangdong Polytechnic. More than 75% of the respondents expressed positive views of the created CHLD animation. The study’s findings and the created animation reaffirmed the effectiveness of using digital media to preserve and promote CHLD culture, especially among China’s younger generation. This also offers a valuable reference for similar studies contributing to the sustainable development of ICH in the Chinese context.

Authors: Cengiz Tırpan Esra
Published: December 2024

As generative artificial intelligence (generative AI) technology rapidly develops, new tools are being introduced to the market, and its use in many areas, from education to healthcare, is quickly increasing. Therefore, ethical research must keep pace with these developments and address the new challenges. In this way, AI can benefit society and prevent potential harm. This study was conducted to identify ethical issues in the use of generative AI, highlight prominent issues, and provide an overview through a systematic literature review. A systematic search was conducted in Scopus, Web of Science, and ScienceDirect databases to retrieve articles examining ethical aspects of generative AI with no year restrictions. The search terms were "generative artificial intelligence," "generative AI," "GenAI," or "GAI," with the combination of "ethic," "ethics," or "ethical." Studies were selected using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Forty-three articles were included in the review after the screening process. According to the research results, the "justice and fairness" principle was emphasized in all the articles examined. The least examined ethical principles were the principle of "solidarity", which expresses unity in society or group, and the principle of "dignity", which means the value an individual feels for himself and his rights. The authors of the 43 articles are mainly from the United States (n = 31), followed by China (n = 15) and the United Kingdom (n = 13). Of the 43 articles reviewed, 41 mentioned ChatGPT, albeit as an example. This study reviews the literature on the ethical use of generative AI and presents challenges and solutions.

Authors: Erkuş Umut , Öztürk Abdülkadir
Published: December 2024

It can be said that the metaverse concept has gained an essential place in the rapidly developing world of digital technology and virtual reality. It is possible to state that this virtual universe reveals new perspectives on consumer experiences, preferences and consumption habits. Understanding how traditional consumer behaviours occur in the Metaverse and how these new interactions shape existing consumption patterns is essential. Considering the increasing academic interest and volume of studies in this field in recent years, this study aims to identify the literature on consumer behaviour in the Metaverse and prepare a conceptual framework for possible future studies. The analysis and evaluations made by the bibliometric analysis method tried to reveal topics such as which topics come to the fore in understanding consumer behaviour in the context of the Metaverse universe and which keywords are more frequently included in the literature. All studies (articles, papers, book reviews, etc.) in the Web of Science Core Collection database were scanned using the keyword "Metaverse consumer behaviour", and the data were analysed using the VOSviewer program. Ninety-eight studies conducted between 2010 and 2024 were analysed. According to the findings, there has been a significant increase in the studies on consumer behaviour in the Metaverse universe in recent years, especially in 2023 and 2024. The findings also show that the most frequently cited keywords in the studies are 'Metaverse', 'Consumer Behaviour' and 'Virtual Reality', the most cited authors are D. Gürsoy, A. Dhir and S. Malodia, and the most cited countries are the United States and India. It can be said that Turkey's contribution to the literature in this field is limited. When the bibliometric studies in the literature are examined, no study has been found in which studies on consumer behaviour in the Metaverse universe have been subjected to bibliometric analysis. It is thought that the study will contribute to filling the gap in the literature to a certain extent due to the general map and the analysis made as a result of bibliometric analysis.

Published: December 2024

As a result of the rapid development of technology and easier access, social media addiction has become the biggest problem for adolescents of this age. This research aimed to examine the effects of self-perception, depression, and social media addiction on adolescents. The research was conducted using a relational survey design with 475 adolescents. The participants comprised 266 (56%) girls and 209 (44%) boys attending various middle and high schools. They are studying at different grade levels in Turkey. The data were collected face-to-face in 2023-2024 when the pandemic restrictions were lifted. Within the scope of the research, the Personal Information Form prepared by the researcher, the Social Media Addiction Scale for Adolescents (SMAAS), the Self-Perception Scale for Adolescents, and the Kutcher Adolescent Depression Scale (KADS) were used as data collection tools to determine the personal information of the participants. After testing the proposed model using Structural Equation Modeling (SEM), it was revealed that depression and self-perception have a significant effect on social media addiction. According to the results of the study, it was determined that the level of depression predicted social media addiction (SMA). In addition, it was found that the indirect effect of adolescents' depression levels on social media addiction through their self-perception was statistically significant.

Kudüs şehri, üç monoteist din için kutsal bir şehirdir. Bu şehrin egemenliği ile ilgili tartışmalar, 20. yüzyılın başlarında Siyonizm fikrinin yeşermesi ve İngiliz mandasının başlaması ile ortaya çıkmıştır. 1948’de Kudüs’ün batısını, 1967’de doğusunu işgal yoluyla ele geçiren İsrail, bu şehrin uluslararası hukuk statüsünü çiğnemiştir. Şehir ile ilgili Birleşmiş Milletler kararlarının uygulanmayacağını ilan etmiştir. Bu ilana karşı somut ve fiili adım atılamamış ve Birleşmiş Milletler sistemi kilitlenmiştir. Bu kapsamda İsrail’in uluslararası hukuku ihlal ettiği ve bu ihlallere karşı Birleşmiş Milletler sisteminin çözüm üretemediği açıktır. Şu halde, toprakları işgal ve silahlı saldırı altında olan Filistin halkının meşru savunma hakkı kapsamında harekete geçmesi ve kolektif meşru savunma kapsamında bazı devletleri ülkesine davet etmesi gerekmektedir.

Makale, yapay zeka (YZ) ve makine öğrenimi süreçlerinde eserlerin girdi olarak kullanımı ile fikri haklar arasında ilişkiyi ele almaktadır. YZ öğreniminde kullanılan büyük veri setleri arasında telif hakkıyla korunan eserlerin bulunması, hukuki ve etik sorunlara yol açmaktadır. Özellikle sanat, edebiyat ve müzik eserlerinin kullanımı, eser sahiplerinin haklarının ihlali riskini taşır. YZ şirketleri aleyhine açılan ilk davalar telif hakları ihlali ile ilgilidir. YZ şirketleri eserlerin girdi olmadığı bir YZ sisteminin imkansız olduğunu dile getirmektedirler. Bu kabul karşısında insanoğlunun, eser sahiplerinin haklarını ihlal etmeyecek çözümler bulması gerekmektedir. Mevcut durumda adil kullanım öne çıkmaktadır. Adil kullanım doktrini bir esneklik sağlarken öngörülmezlik de getirmektedir. Avrupa Birliği’nin yeni mevzuatları, şeffaflık ve veri paylaşımı konularında düzenlemeler getirerek, YZ öğreniminde eserlerin kullanımını denetlemeyi hedeflemektedir. FSEK açısından ise bir istinasa yoktur. Bu düzenleme olmayışı bir fırsata dönüşebilir. Makale, YZ öğrenimi ve telif hakları arasındaki dengeyi sağlamak için mevcut hukuki çerçeveyi ve çözüm önerilerini tartışmaktadır.

Physical properties of whitlockite-type Ca3 (VO 4 ) 2 orthovanadate can be modified by incorporation of isovalent or aliovalent cation substituents. In this paper, the features of the crystal structure of Ca9La(VO4)7 and Ca10Li(VO4)7 whitlockite-type crystals grown by the Czochralski method with substitution by aliovalent La or Li ions are studied. Refinement of the structure using the Rietveld approach allowed us to determine the unit cell parameters and site occupancy. According to the data of polarization-optical studies, the formation of a strip-like ferroelectric domain structure with spontaneous polarization parallel to the third-order axis was established in the Ca9La(VO4)7 single crystal. It has been established that Ca10Li(VO4)7 is an antiferroelectric at room temperature. The correlations between Vickers hardness and fracture toughness values and the degree of crystal perfection are discussed.

The paper reports results of pure CsMgCl3 and CsMgCl3:xEu2+ (x = 0.5, 1 and 1.5 mol. %, in the charge) single crystals growth and investigations of their functional properties. The crystals were grown by Bridgman method and the entry ratio of Eu2+ into CsMgCl3 was determined as 0.021, i.e. in all the europium-activated samples the concentration of the activator was at the level of admixtures. The photoluminescence spectra of CsMgCl3:Eu2+ show that Eu enters in the crystal both as Eu2+ form (main) and Eu3+ one (trace amounts). The shape of the spectra are dependent on excitation wavelength (λex): at λex=350 nm the shape of the spectra corresponds to those of Eu2+ activated halides (the maxima in 470–490 nm range) and at λex=275 nm the shape of spectra corresponds to those of Eu3+-activated phosphors. X-ray luminescence spectra include two bands with the maxima at 460 nm proper for Eu2+- activated halides and at 545 nm which could be ascribed to the distortions of CsMgCl3 crystal lattice due to entering of the slightly isomorphic Eu2+. The X-ray luminescence decay time is estimated within 0.8–0.9 µs. CsMgCl3:Eu2+ crystals possess the light yield of ca. 150 % vs. BGO (Bi4Ge3O12) and it is impossible to determine the concentration dependence since only traces of the activator are incorporated inside CsMgCl3:Eu2+ crystals. The best energy resolution is 18 %.

It has been shown that during electrolytic hydrogenation of wire samples of the Zr1Nb alloy, a layer of 9.5 μm thick anisotropic zirconium hydride nanocrystals with a thickness of ≈9.5 µm is formed on the surface, which leads to a decrease in the shear modulus by 10% in pre-annealed samples and to a significantly reduced effect in deformed ones. The latter is a consequence of the competition of two factors: a decrease in modulus due to the direct formation of the δ hydride ZrH1.66 and an increase due to the relaxation of internal stresses. The observed effect of a decrease in the electrical resistivity of a wire sample as a result of hydrogenation is discussed.

Authors: Abdikairov Bekmurat , Juliev Mukhiddin , Kholmurodova Madinabonu
Published: December 2024

Soil is part and parcel of operating essential functions of ecosystems. Its degradation including salinization may affect negatively both agriculture and human life. Soil salinization is a form of environmental destruction resulting in loss of soil quality, especially in dry and semi-arid zones including both primary and secondary salinization. Today, salt-affected areas cover 7% of the Earth’s surface with hotspots in the United States, Argentina, Pakistan, China, Sudan, and many states in Central and Western Asia existing in a minimum of 100 countries. Timely and effective management is required to preserve soil fertility for the next generation. Currently, modeling is an effective approach to identify, evaluate and predict soil salinization distribution. Modeling with remote sensing techniques is widely used to identify salt-affected soil, map saline locations, and estimate salinity levels. Today, a lot of geostatistical techniques are applied to predict soil salinity over time including Ordinary Kriging, Co-kriging and Indicator Kriging. The current study originated as a review with the purpose of exploring the scientific background of soil salinity modeling throughout the world. Our research, which includes 177 Scopus-indexed final published articles in English, focuses at publishing trends, types, top publishers, notable authors, affiliated institutions, geographical and thematic emphasis areas, co-authorship and keyword occurrences. Additionally, this paper provides a review of the most popular models and conditioning factors. Among various models, multiple linear regression was used as the most prevalent model type for soil salinity estimation in 10.1% of the publications, and electrical conductivity is considered as the most value conditioning factor in 19.2% of analyzed papers. Finally, it is concluded that recent technological developments in remote sensing are significant factors in increasing research interest in soil salinity modeling.
Study of petrophysical properties of deep-seated Meso-Cenozoic sediments within the North Apsheron system of uplifts
Authors: Gurbanov V. Sh. , Hasanov A. B. , Abbasova G. G.
Published: December 2024

This article presents our research on the depth dependence of the reservoir properties oil and gas bearing deposits of the Meso- Cenozoic age within the Apsheron uplift. The petrophysical features and patterns of change at depth of the Meso-Cenozoic sediments of the deposits of the Apsheron Bank and Western Apsheron were studied. Despite the fact that the history of the discovery and processing of the abovementioned deposits dates back to the 1950s, some geophysical features associated with these deposits still remain relevant. In particular, from literary sources it is known that the clay content of oily reservoirs of the Apsheron Archipelago tends to grow in a southeast direction. Reservoirs consist mainly of rounded, semi-rounded and angular rounded grains of isometric shape. The average carbonate content in the Apsheron Bank is up to 16.2%, and the average carbonate content in Western Apsheron is up to 13.8%. The average porosity here is 22%, with slight differences in the lower and upper sections. Due to the presence of carbonate material as cement, carbonization in sand reservoirs varies between 2.9-31.8%, and the porosity coefficient is 6.8-25.6%. In general, in deposits of the Archipelago, sand reservoirs have high permeability, on average characterized by permeability coefficients of 139*10-15 m2. From the results of our study based on the core samples from wells drilled in the territory, the general porosity of rocks involved in the depth-section is characterized by unstable values. Nevertheless, in general, there is a tendency to decrease in porosity in depth. So, in particular, in the context of the Apsheron Bank with an average value of porosity of 8%, the pattern of its decrease is described by the linear equation Y = – 0.16x + 12.59 and is on average 0.6% for every 100 m. For Western Apsheron with a sharper the change in porosity in depth, the average value is 14.2%, and the tendency to decrease with increasing depth is weaker and is 0.25% per 100 m. To determine the causes of the observed variability of porosity at different depths, we studied the effect of the degree of carbonate content of various rock samples on porosity. As a result, in both deposits (Absheron Bank and Western Apsheron) the inverse proportion of the porosity of the rocks and the values of carbonate was confirmed. Although the separate carbonate contents negatively affect the porosity of reservoir rocks, the combined effect of carbonate and clay contents differs for the studied deposits.
Comprehensive classification of Red-colored Serie rocks from the eastern flank of the South Caspian Basin (Jigalybek field) based on reservoir and geophysical properties

Published: December 2024

The Absheron-Prebalkhanian tectonic zone, known as the Absheron threshold, has been the subject of extensive study by researchers for nearly hundred years. This region holds significant interest due to its strategic location between the well-known oil and gas-bearing areas of Absheron and Cheleken. This paper presents a comprehensive classification of Red-colored Serie (RCS) rocks from the Jigalybek (Jdanov Bank) field (located in the eastern part of the South Caspian Basin) based on reservoir and geophysical properties. The study includes a detailed analysis and classification of rocks into different classes, considering both reservoir and non-reservoir properties. A total of 42 core samples were analyzed to determine key geophysical parameters, including R-1-R-5, ρLL, SP, ΔJγ, ΔJpγ, and Δd. The analysis revealed four distinct classes of rocks based on their reservoir properties, identifying two types of highly permeable and moderately permeable reservoirs, and two types of non-reservoirs comprising compacted low-permeability clays and pure clays. The geophysical classification further differentiated the rocks into oil-bearing, water-bearing, and non-reservoir types, emphasizing the geophysical signatures that distinguish between these categories. A comprehensive classification approach was also applied, combining six reservoir properties and ten geophysical parameters to refine the distinction between water-saturated and oil-saturated reservoirs. The study demonstrated that water-saturated reservoirs are generally more clay-rich and less porous than oil-saturated reservoirs, providing a robust methodology for identifying and characterizing different types of reservoirs in the field. Such a classification system is valuable for improving the accuracy of reservoir identification and characterization, leading to better resource management and extraction strategies in the Jigalybek field. The results underscore the importance of integrating multiple geophysical and reservoir parameters to achieve a more precise classification and understanding of subsurface rock properties.

Authors: Pogorelova Yelena Yu. , Aghajanov Fikrat T.
Published: December 2024

This study explores the identification and characterization of non-anticlinal traps within the southeastern part of the Yevlakh-Agjabedi Depression using advanced seismic exploration techniques. With an emphasis on the application of seismic data, particularly the Common Reflection Point (CRP) and 3D seismic methods, the research focuses on detecting stratigraphic traps formed by lateral and vertical variations in rock properties such as lithology, porosity, and facies. Primary and secondary stratigraphic traps are examined, with examples including stratigraphic traps formed by sedimentation and diagenesis processes. Building upon advancements in seismic exploration, this study applies state-of-the-art techniques to delineate and understand stratigraphic traps within the south-eastern part of the Yevlakh-Agjabedi Depression. By leveraging the CRP and 3D seismic methods, this research aims to overcome traditional limitations and provide a comprehensive analysis of these subtle geological structures. The integration of seismic data with well-logging and drilling data enhances the precision and reliability of trap identification, offering insights that are crucial for effective resource exploration and management. The study concludes that the application of advanced seismic exploration techniques, such as the Common Reflection Point (CRP) and 3D seismic imaging, has significantly improved the detection and characterization of stratigraphic traps in the geologically complex Yevlakh-Agjabedi Depression. By integrating seismic data with well-logging and drilling information, researchers have overcome challenges such as seismic noise and complex trap geometries, leading to more accurate mapping of these non-anticlinal traps. This integration has not only enhanced the identification of subtle variations in lithology and facies but also revealed the substantial hydrocarbon potential of the region. The findings emphasize the critical role of advanced geophysical methods and interdisciplinary approaches in optimizing exploration strategies and resource development in geologically similar settings. Future research should focus on refining seismic interpretation techniques and exploring deeper reservoirs to fully unlock the potential of stratigraphic traps for sustainable resource extraction.

The study aims to investigate the thermal comfort conditions of the Dnipropetrovsk region for the period 1991–2020, based on modern approaches. The physiologically equivalent temperature (PET) was used to determine the thermal bioclimate in the Dnipropetrovsk region. PET calculations were performed using the RayMan model, which is a microscale model for calculating radiation fluxes in simple and complex environments. Daily data measured at 00:00, 03:00, 06:00, 09:00, 12:00, 15:00, 18:00, and 21:00 UTC from six weather stations of the meteorological network of the Ukrainian Hydrometeorological Centre (Dnipro, Kryvyi Rih, Pavlohrad, Nikopol, Komisarivka, Synelnykove) for the period 1991–2020 were used to analyze thermal comfort conditions in the Dnipropetrovsk region. The study of the bioclimatic conditions of the Dnipropetrovsk region showed that in the winter months (December–February), extreme cold stress prevails, with a frequency of occurrence ranging from 94.5% to 99.8% across the region. Starting from the second decade of May until the second decade of September, heat stress of different intensities was observed in the region, with the highest frequency in the second decade of July, ranging from 39.1% in Dnipro to 50% in Nikopol. The highest frequency of strong and extreme heat stress was observed in the first decade of August, ranging from 10.7% to 17% in different parts of the region. During daytime hours, the highest frequency of extreme heat stress in the region was observed in the first decade of August, ranging from 5.1% to 13.3%. The daily variation of PET during the period with the most strenuous hot conditions throughout the year (July’s third decade and August’s first decade) was similar to the daily variation of air temperature, with minimum values after sunrise (03:00 UTC) and maximum values after midday (12:00 UTC). The most comfortable conditions were found in the morning and evening hours (06:00 UTC and 18:00 UTC, respectively). In the city of Dnipro, the number of heat waves (HW) increased from 16 to 33 in the period 1991–2020 compared to the normal climatic period (1961–1990). The mean PET value during HW events in Dnipro during the period 1991–2020 was 39.7°C, while during the summer months, it was nearly 10°C lower (29.9°C).

This study aims to characterize the properties of the ternary molybdate Rb5(Ag1/3Hf5/3)(MoO4)6, which was previously identified during phase equilibrium investigations in the Ag2MoO4–Rb2MoO4–Hf(MoO4)2 system. A ternary molybdate Rb5(Ag1/3Hf5/3)(MoO4)6 was obtained through a solid-state reaction. It was found that the compound crystallizes in the trigonal space group R c and melts at 596 °C with decomposition. Its structure was refined using the Rietveld method. The crystal structure consists of a mixed framework composed of isolated (Ag/Hf)O6 octahedra and MoO4 tetrahedra, interconnected through shared oxygen vertices. Large voids within the framework accommodate two types of rubidium atoms. Using the powder XRD data recorded over 30–400 °C, the principal components of the thermal expansion tensor were determined. Rb5(Ag1/3Hf5/3)(MoO4)6 can be classified as a material with high thermal expansion coefficient (αV = 36.7∙10–6 °С–1 at 400 °C). At elevated temperatures, the compound exhibited significant ionic conductivity, reaching 1.7·10−3 S/cm at 480 °C with an activation energy Еа = 0.8 eV with oxygen ions as the probable charge carriers. Energy barriers for one-, two-, and three-dimensional transport in the compound were theoretically evaluated using the softBV program and bond valence sum maps (BVS).
A Odisseia de Clarice Lispector
Authors: Lopes da Costa Lorena
Published: December 2024

Este texto se dedica a um estudo de recepção clássica e defende que Uma Aprendizagem ou o Livro dos Prazeres é uma releitura da Odisseia, capaz de estabelecer com a fonte antiga uma relação ambígua que mobiliza tal característica como ferramenta para enfrentar a obra precedente. O livro de Clarice Lispector tanto incorpora personagens e hábitos de uma determinada interpretação da poesia épica quanto busca romper com eles, revelando outra camada interpretativa do poema. Para apresentar como o material odisseico é reescrito na literatura clariceana, o presente artigo dialoga ainda com outros textos, especialmente aqueles que, publicados nas páginas femininas dos jornais para os quais a autora trabalhou, demonstram seu interesse pelo que podemos chamar de literatura feminista, especialmente por Virginia Woolf.
A temporalidade da catástrofe palestina
Authors: Ferreira de Figueiredo Carolina
Published: December 2024

O presente artigo tem por objetivo analisar a obra escrita pelo historiador sírio Constantine K. Zurayk, intitulada Ma’na al Nakba, O Significado da Nakba, acerca da expulsão da população palestina, em meio ao processo de criação do Estado de Israel em 1948. A obra, publicada no mesmo ano, apresenta reflexões sobre o problema palestino relacionado a uma causa árabe, bem como um efeito do Sionismo. A partir desta publicação, busca-se refletir sobre as transformações da temporalidade e da escrita da história palestina em relação a esta dimensão basilar: a Nakba e seus desdobramentos para a população e para o território. Além de Zurayk, visualiza-se outras produções contemporâneas ao autor, assim como uma produção acadêmica mais recente, sobretudo a partir de 1970. Apresenta-se a formação de uma historiografia sobre a Nakba, bem como discute-se permanências e mudanças nas perspectivas sobre a Nakba e sua relevância no presente para se pensar a “questão palestina”.
Ausência de longa duração e Presença ausente como desresponsabilização
Authors: Thomaz Pereira Affonso
Published: December 2024

Este artigo analisa a emergência de diferentes temporalidades e linguagens políticas com a volta dos militares à cena política. Parte-se da premissa de que, desde a Lei da Anistia e da Constituição de 1988, uma vez assegurados seus privilégios e imunidades, eles estabeleceram mecanismos eficientes de regulação de sua presença / ausência do cenário político. Durante a Nova República (1985 - ), houve um regime de atuação militar de baixa intensidade até o golpe de 2016 e as eleições de 2018, quando o Alto Comando e altas patentes reassumiram protagonismo político. Essa alta exposição exigiu dos militares novas formas de produção de sua representação explicitando temporalidades, agenciamentos e categorias próprias desse universo e que, dada sua ubiquidade, desafiam a percepção ordinária da história. Esse contexto de crise (2016-2022) nos impeliu a analisar a mobilização desses mecanismos de presença / ausência da percepção pública como formas de desresponsabilização política dos militares ao longo da história recente.
Memória do capitalismo como ausência
Authors: Silveira Bauer Caroline , Ferreira Souza Leandro
Published: December 2024

A Covid-19 originou diversos projetos de arquivamento da experiência pandêmica e de memorialização de suas vítimas, entre eles, o Memorial Inumeráveis. Entretanto, observa-se nessas iniciativas a inexistência de menções ao capitalismo e à razão neoliberal como promotores da pandemia e dos milhões de vitimados. Este ensaio reflete sobre essa ausência de inscrição e reconhecimento e propõe uma leitura do Memorial Inumeráveis como uma “memória do capitalismo”. Argumenta-se que a pandemia de Covid-19 resulta de uma forma específica de relacionamento dos seres humanos com os ecossistemas, e que é possível inscrever e reconhecer a “memória do capitalismo” a partir de um ato de enunciação característico do trabalho de memória. Desta forma, a interpretação do Memorial Inumeráveis como uma “memória do capitalismo” contribui para explicitar os mecanismos de produção de naturalização do sistema capitalista e do neoliberalismo.

Preterm birth (PTB), a major cause of neonatal morbidity and mortality worldwide, is increasing in many countries, particularly in low- and middle-income countries. PTB is a difficult-to-manage condition, where symptomatic treat-ment improves neonatal outcomes but does not reduce its incidence. Reduction in preterm birth can be achieved by prophylactic progesterone in women with a history of preterm birth, in those patients in whom short cervical length has been identified by routine transvaginal ultrasound, and by personalized preconception care that takes into account history and both environmental and individual risk factors.

A fairly common neoplasm of the temporal bone is a paraganglioma. The incidence of this pathology is 1 : 30,000 of the population, with a predominant prevalence in women. Despite advances in medical technology, the diagnosis and treatment of temporal bone paraganglioma has its own difficulties. This is primarily due to the late treatment of patients to the doctor, an imperfect diagnostic algorithm and the peculiarities of the location and abundant vascularization of this tumor. A clinical case is presented: a patient with a neoplasm of the left middle ear (paraganglioma type C according to Fish), left-sided deafness, neuropathy of the facial nerve (paresis of facial muscles of the III degree on the House-Brackmann scale). It is worth noting the importance and necessity of a multidisciplinary approach, timely decision-making both at the stage of diagnostic examination and during treatment, which will avoid severe complications of this pathology.

The excessive release and accumulation of carbon dioxide in the atmosphere is a major global issue with several negative environmental consequences, including global warming. Various approaches are used to eliminate these negative effects, with the main focus being on reducing carbon dioxide emissions and achieving a zero-carbon balance. In addition to decline fossil fuel mining and use, biosequestration is being considered as a potential solution. Microalgae are particularly promising in this regard, as they can serve as sinks for carbon dioxide when used in biotechnological processes. Some strains of microalgae from the genus Bracteacoccus Thereg, have been studied for their ability to synthesize valuable products. However, the ability to absorb carbon dioxide by these objects has not been studied, in particular, when the concentration of available nitrogen in the nutrient medium changes. The study found that high levels of bioavailable nitrogen increase the average rate of absorption of carbon dioxide, while maximum absorption occurs when the culture leaves the lag-phase. The rate of carbon dioxide fixation and its amount absorbed by Bracteacoccus minor (MZ-Ch31) directly depend on biomass productivity and chlorophyll concentration.
