A construção discursiva do sujeito mulher-policial em perfis do Instagram
Authors: Santana Cremilton de Souza , Cortes Gerenice Ribeiro de Oliveira
Published: July 2024

Neste estudo, objetivamos analisar como o sujeito mulher-policial se constitui e é constituído discursivamente na rede social Instagram. Para tanto, amparamo-nos na Análise de Discurso (AD) de perspectiva pecheuxtiana, além dos aportes teóricos acerca do discurso digital. O corpus discursivo consiste em um recorte de quatro sequências discursivas (SDs), coletadas a partir de publicações que abordam a temática da mulher-policial na rede social Instagram, bem como de alguns comentários das respectivas postagens. As análises mostraram que a construção do sujeito discursivo mulher-policial sofre determinações históricas e ideológicas das formações discursivas (FDs) machista e militarista, além de outros atravessamentos discursivos. Nessa trama discursiva, as formações imaginárias do sujeito mulher e do seu lugar social, como também o imaginário da instituição polícia e do sujeito policial, tornam-se também determinantes para a movimentação dos sentidos e o funcionamento das diversas posições-sujeito no discurso na/em rede.

Entre humano y no humano: las cosmovisiones amazónicas en murales de Amazonarte Perú y el caso de Pucallpa
Authors: Yoza-Mitsuishi Katia
Published: July 2024

En las cosmovisiones amazónicas, el equilibrio en las relaciones entre humanos y no humanos es central para el bienestar de las comunidades más-que-humanas, lo cual coincide con movimientos ambientalistas actuales. Lamentablemente, no hay suficientes estudios sobre las cosmovisiones amazónicas en medios urbanos como, por ejemplo, murales. En este artículo, analizo una selección de murales de artistas de orígenes diversos reunidos por la asociación Amazonarte Perú y ubicados en la ciudad amazónica de Pucallpa. Sostengo que, cuando los murales son entendidos desde las mismas cosmovisiones amazónicas y el perspectivismo amerindio que las sintetiza, revelan una original resiliencia socioecológica por los derechos culturales y territoriales de los pueblos indígenas amazónicos. Los murales no solo superan la dicotomía naturaleza/cultura y son el resultado de alianzas entre indígenas y no indígenas, sino que también trascienden el concepto de “representación” al mostrar y materializar la subjetividad y la agencia de los no humanos a través del arte urbano.

Authors: Thomas William Wayt , Silva Filho Pedro Joel Silva da , Reginato Marcelo
Published: July 2024

Background and aims – We tested the integrity of Rhynchospora sect. Pleurostachys, understand its evolution and origins, and test the phylogenetic separation of three morphologically distinct taxa.

Material and methods – We used the chloroplast marker trnL-F and the two nuclear markers nrETS and nrITS in our phylogenetic analysis.

Key results – We demonstrated that R. sect. Pleurostachys is monophyletic and that the section is divided into two large clades with the early divergent species in each clade occurring outside the Atlantic Forest of Brazil. The molecular analysis also confirmed the distinctness of the three species new to science.

Conclusions – Rhynchospora sect. Pleurostachys probably originated outside the Atlantic Forest but diversified there. The three taxa are described as species new to science: Rhynchospora barbosae, R. hamadryadis, and R. eremica, from the tropical semi-deciduous and deciduous forests of Bahia and Espírito Santo, Brazil, are illustrated and compared to other related species of the section.
Effects of Emotional States on the Spatial Perception
of Youth Athletes with Different Alerting Efficiencies
Authors: Wang Lian , Meng Qiao , Lipowski Mariusz
Published: July 2024

The purpose of this study was to explore the role of the attentional alerting network in spatial perceptual processing in youth athletes under different emotional states. Two hundred and fifty participants were recruited to assess alerting efficiency using the Attention Network Test and were divided into high and low alerting efficiency groups based on the front and back 27% of the alerting scores as a dividing metric. Subsequently, participants completed the Spatial Perception Response Task under different emotionally induced conditions. Results showed a correlation between alerting efficiency and spatial perception, the higher the alerting efficiency, the faster and more accurate the spatial perception response. Emotion and spatial location interacted significantly (p < 0.05), and subjects in the angry emotional state had faster spatial responses to the lower left visual field than those in the happy emotional state. Moreover, an interaction was found for location accuracy (p < 0.05). The high alerting efficiency group showed lower accuracy in the anger state than in the happy state. These findings suggest that alerting efficiency can be used as an objective indicator for assessing the spatial perceptual ability of youth athletes, which provides empirical evidence for mental selection and perceptual training of youth athletes.

Published: July 2024

The study aims to quantitatively assess the availability of various infrastructures for doing business and identify the main barriers in the infrastructure industry that hinder the ease of doing business and investment development in regions of Kazakhstan. The authors assessed infrastructure accessibility in Kazakhstan's regions based on an SME managers' survey. They developed an index of infrastructure availability, a practical tool for gauging infrastructure development in a specific region or country. This index is crucial for investment planning and developing relevant sectors of the national economy. The findings revealed that no region in Kazakhstan has a good infrastructure. Access to its most essential types is only at an average level, with the lowest index values observed in Almaty and East Kazakhstan regions. The analysis of SMEs' problems with access to infrastructure highlighted bureaucracy and difficulties in obtaining permits, high wear and tear of networks, and high connection costs as the main issues. The authors underscore the increasing global economic and geopolitical risks that lead to fundamental changes in Central Asia, particularly Kazakhstan, which has excellent potential for developing transit routes between East and West. They advocate for active investment in infrastructure projects as a solution. According to expert forecasts, if Kazakhstan invests at least 4% of its GDP annually, it can completely replace and modernize the republic's worn-out transport infrastructure by 2040, leading to significant economic benefits. The authors will use the study's results to create regional indices of doing business in Kazakhstan.

Published: July 2024

The exposure and occurrence of the residues of drugs and pharmaceuticals has become very common in different matrices such as biological samples (e.g., blood, plasma, urine) or in environmental samples, such as soil, sediment, and water. These residues may accumulate in the human body and may create detrimental effects after
long-term exposure. The detection of the presence of these toxic components even up to the nano level or lower level may be carried out by the application of advanced hyphenated analytical instrumentation. In this direction, various chromatographic analytical methods are available, but recently, nanoliquid chromatography (NLC) has
become more popular among researchers. Nanoanalysis of pharmaceutical drug residues by nano-liquid chromatography has been a state-of-the-art in the area of research and innovation. Its application has become very important in recent years. NLC is a novel method and is applicable for drug analysis, especially for the separation
and detection of chiral compounds. In industrial sectors such as pharma, agrochemical and biomedicine or in research laboratories, enantiomeric separation and determination in samples have received much attention from authorities and researchers. Nano-LC has benefits over other conventional chiral separation have been explained. The basic science of normal separation and chiral separation along with the application of NLC in drug analysis has been well described and reviewed. Moreover, chiral recognition mechanisms are important and are presented herein.
Various modalities of Nano-LC have been described in the article as a step toward Lab on Chip with a green chemistry approach.

Authors: Rani Jyoti , Charan Kali
Published: July 2024

This paper investigates the novel explicit model of the relativistic field equations for radiating fluid ball in the absence of horizon. The inner metric is without shear, symmetry like sphere and undergoes heat flow in radial direction. The inner metric maintains all appropriate thermodynamic and physical parameters analytically as well as
graphically and are matched to the Vaidya external metric across the boundary. Here in the present model, the collapse begins with unlimited mass and radius, and time approaches zero without the event horizon formation. The luminosity is independent of time, and the rate of collapse process will never reach the horizon.
Exílio e Memória na Poesia de Yolanda Morazzo
Authors: Lima Norma Sueli Rosa
Published: July 2024

Análise de quatro livros de Yolanda Morazzo que foram reunidos em Poesia Completa (1954-2004) na investigação de uma poética da diáspora que atualizou a história oficial a partir do exercício da memória, em trânsitos por Portugal e por Angola, nos quais manteve os elos identitários e culturais com Cabo Verde. A sua extensa obra poética evidencia a resistência da voz feminina que, nos exercícios da oralidade e de outras modalidades performáticas, estão alinhadas com a nação cabo-verdiana, a qual constantemente relembrou e reavivou em seus versos de diáspora, na remissão da crioulidade pela diferença que rearticulará projetos globais, em tensão entre o hegemônico e o contra-hegemônico. O artigo percorre a recepção do que foi considerado subalterno na perspectiva das histórias locais que, embora identifiquem esse lócus de origem, também procuraram a reversão de preconceitos que inspiraram na crença comum de que somente as pessoas que são de algum lugar considerado privilegiado podiam “falar”. Com base em Carmen Lucia Tindó Ribeiro Secco, Edward Said, Inocência Mata, Manuel Brito-Semedo, Simone Caputo Gomes, Toni Morrison, Walter Mignolo e outro/as percebo a poesia reivindicativa da inclusão de segmentos sociais injustiçados, na Literatura representativa do encontro com o outro.

Possible provenance of IRD by tracing late Eocene Antarctic iceberg melting using a high-resolution ocean model
Authors: Elbertsen Mark Vinz , van Sebille Erik , Bijl Peter Kristian
Published: July 2024

Abstract. The Eocene-Oligocene Transition is characterised by the inception of the large-scale Antarctic ice sheet. However, evidence of earlier glaciation during the Eocene has been found, including the presence of ice-rafted debris at Ocean Drilling Program Leg 113 Site 696 on the South Orkney Microcontinent (Carter et al., 2017). This suggests marine-terminating glaciers should have been present in the southern Weddell Sea region during the late Eocene, generating sufficiently large icebergs to South Orkney to survive the high Eocene ocean temperatures. Here, we use Lagrangian iceberg tracing in a high-resolution eddy-resolving ocean model of the late Eocene (Nooteboom et al., 2022) to show that icebergs released from offshore the present-day Filchner Ice Shelf region and Dronning Maud Land could reach the South Orkney Microcontinent during the late Eocene. The high melt rates under the Eocene warm climate require a minimum initial iceberg mass on the order of 100 Mt and an iceberg thickness of several tens of metres to be able to reach the South Orkney Microcontinent. Although these sizes are at the larger end of the present-day range of common iceberg sizes around Antarctica, the minimum estimates are not unfeasible and, hence, the present study confirms previous findings suggesting glaciation and iceberg calving were possible in the late Eocene.
Hemispheric asymmetry in recent stratospheric age of air changes
Authors: Dube Kimberlee , Tegtmeier Susann , Ploeger Felix , Walker Kaley A.
Published: July 2024

Abstract. Many stratospheric trace gases, including O3, HCl, and NOy, have opposing trends in the Southern Hemisphere (SH) compared to the Northern Hemisphere (NH) during the last two decades. Some of this difference is due to hemispherically asymmetric changes in the rate of transport by the Brewer-Dobson Circulation (BDC), and some is due to ozone depletion and recovery. The mean Age of Air (AoA) is a common proxy for the transport rate by the BDC in models, however it cannot be directly measured. We use observations from the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) along with results from the Chemical Lagrangian Model of the Stratosphere (CLaMS) to derive AoA anomalies and AoA trends. The AoA is derived using observations of N2O, CH4, and CFC-12, all long-lived trace gases with tropospheric sources. We also consider CLaMS simulations driven with four different reanalyses (ERA5, ERA-Interim, JRA-55, MERRA-2). We find that, irrespective of which trace gas or reanalysis is used, air in the NH aged by up to 0.3 years/decade relative to the SH over 2004–2017. The maximum hemispheric difference in aging occurs in the middle stratosphere, near 30 hPa (~24 km). We also show that the aging rate in the NH becomes smaller when the analysis is extended to 2021. The observed aging in the NH middle stratosphere contradicts model predictions of a decrease in stratospheric AoA in response to rising atmospheric greenhouse gas levels. However, the smaller aging rate during 2004–2021 compared to 2004–2017 provides some evidence that the NH aging is impacted by decadal variability and the limited length of the observation period.
A climate suitability index for ecological habitats applied to terrestrial arthropods in the Mediterranean Region
Authors: Ciarlò James M. , Borg Inguanez Monique , Coppola Erika , Micallef Aaron , Mifsud David
Published: July 2024

Abstract. Climate change poses significant threats to global biodiversity, particularly impacting arthropods due to their sensitivity to shifts in temperature and precipitation, as well as other environmental conditions. These changes impact the suitability of their habitats, alter ecological interactions, and consequently affect the distribution and survival of species. Understanding how climate variability influences the ecological niches of arthropods is crucial for predicting future biodiversity patterns and implementing effective conservation strategies. This study introduces a simple index designed to assess the climate suitability of ecological habitats, with a specific focus on terrestrial Mediterranean arthropods. This approach leverages Regional Climate Model data to construct a climatology of a species' preferred habitat, based on historically observed locations. This index offers a straightforward and rapid means to assess the resilience and vulnerability of arthropod populations, aiming to shed light on how climate change could affect their fundamental niches. The analysis revealed that the method is most reliable for species with observations exceeding 1000 points, and climate datasets of high resolutions (although the latter had a smaller influence on the results). This study offers a proof-of-concept for the proposed index, demonstrating its potential utility in guiding conservation strategies and mitigating the adverse effects of climate change on arthropod habitats.
A globally distributed dataset of coseismic landslide mapping via multi-source high-resolution remote sensing images

Published: July 2024

Abstract. Rapid and accurate landslide mapping following extreme triggering events is critical for emergency response, hazard prevention, and disaster management. Artificial intelligence- based approaches enable rapid landslide mapping, yet the lack of a high-resolution globally distributed and event-based dataset poses a severe challenge in developing generalized machine learning models for landslide detection. This paper addresses this issue by designing a diverse coseismic landslide dataset, the Globally Distributed Coseismic Landslide Dataset (GDCLD), which includes multi-source remote sensing images (i.e., PlanetScope, Gaofen-6, Map World, and Unmanned Aerial Vehicle) encompassing various geographical and geological backgrounds worldwide. The GDCLD can be accessed through this link: https://doi.org/10.5281/zenodo.11369484 (Fang et al., 2024). Furthermore, we evaluate the potential of GDCLD by analyzing mapping performance of the seven most popular semantic segmentation algorithms. We further validate the generalization capabilities of the dataset by deploying the models on three types of remote sensing images from four independent regions. Besides, we also assess the model on rainfall-induced landslide dataset and achieve good results, demonstrating its applicability in landslide segmentation under other triggering factors. The results indicate the superiority of the proposed dataset in landslide detection, offering a robust mapping solution for rapid assessment in future extreme events that trigger landslides across the globe.
Errorchrons and anchored isochrons in IsoplotR
Authors: Vermeesch Pieter
Published: July 2024

Abstract. Isochrons are usually fitted by “York regression”, which uses a weighted least-squares approach that accounts for correlated uncertainties in both variables. Despite its tremendous popularity in modern geochronology, the York algorithm has two important limitations that reduce its utility in several applications. First, it does not provide a satisfactory mechanism to deal with so-called “errorchrons”, i.e. datasets that are overdispersed with respect to the analytical uncertainties. Second, York regression is not readily amenable to anchoring, in which either the slope or the intercept of the isochron is fixed based on some external information. Anchored isochrons can be very useful in cases where the data are insufficiently spread out to constrain both the radiogenic and non-radiogenic isotopic composition. This paper addresses both of these issues by extending a maximum likelihood algorithm that was first proposed by Titterington and Halliday (1979). The new algorithm offers the ability to attribute any excess dispersion to either the inherited component (“model 3a”) or diachronous closure of the isotopic system (“model 3b”). It provides an opportunity to anchor isochrons to either a fixed non-radiogenic composition or a fixed age. Last but not least, it allows the user to attach meaningful analytical uncertainty to the anchor. The new method has been implemented in IsoplotR for immediate use in Ar/Ar, Pb/Pb, U/Pb, Th/Pb, Rb/Sr, Sm/Nd, Lu/Hf, Re/Os, K/Ca, and U–Th–He geochronology.
Power law between the apparent drainage density and the pruning area
Authors: Yang Soohyun , Choi Kwanghun , Paik Kyungrock
Published: July 2024

Abstract. Self-similar structures of river networks have been quantified as having diverse scaling laws. Among these, we investigated a power function relationship between the apparent drainage density ρa and the pruning area Ap, with an exponent η. We analytically derived the relationship between η and other known scaling exponents of fractal river networks. The analysis of 14 real river networks covering a diverse range of climate conditions and free-flow connectivity levels supports our derivation. We further linked η with non-integer fractal dimensions found for river networks. Synthesis of our findings through the lens of fractal dimensions provides an insight that the exponent η has fundamental roots in the fractal dimension of the whole river network organization.
Varro and the Two-Headed City
Authors: López Barja de Quiroga Pedro
Published: July 2024

An in-depth analysis of Varro’s sentence (quoted by Nonius) on Gracchus judiciary law having created a two-headed city shows how the polygrapher artfully combined Plato’s political considerations on constitutional change with Roman priestly lore (haruspicina). Varro’s sympathies for the optimates find in this sentence its best expression. Posidonius may have been an intermediate stage in the use of these Platonic ideas to understand Roman political history.

La necesidad de alcanzar niveles suficientes de Alfabetización Digital (AD) en docentes se ha vuelto en la actualidad una prioridad en el desarrollo educativo, especialmente en aquellos que participan en programas formativos con niños y adolescentes. Esta propuesta de investigación desarrolla un análisis de autopercepción de docentes mexicanos en educación media superior (EMS), quienes analizan, tanto su condición como de sus estudiantes, respecto a la capacidad de adaptación que se puede experimentar en la apropiación de nuevos conocimientos digitales para su aplicación en la práctica docente virtual o presencial. Para lograr este propósito, se desarrolló una investigación descriptiva-explicativa de naturaleza mixta (dominante cuantitativo) y transeccional, a través de la recolección de datos de 182 docentes en el estado de Chihuahua, México, utilizando un muestreo por conveniencia. La recolección de datos sucedió a través de un instrumento tipo encuesta, integrado por cuatro secciones: datos sociodemográficos, medición de la alfabetización digital docente, percepciones hacia la capacidad adaptativa de estudiantes y medición de la influencia de las materias que imparte en los procesos adaptativos al cambio. Los resultados de la investigación permitieron la identificación de un modelo conceptual breve sobre la AD en docentes, disposición hacia el aprendizaje permanente en cuestiones digitales, formas de manifestación de procesos adaptativos al cambio y las percepciones hacia el impacto presente y futuro de sus asignaturas.
La documentación visual de la Historia: la imagen en los documentales sobre la Guerra Civil en el siglo XXI entre los años 2000 a 2014

Published: July 2024

Esta investigación tiene como objetivo profundizar en cómo se construye una narración audiovisual histórica documental. Se parte de la premisa de que las imágenes, frente a la predominancia de lo textual, son el elemento fundamental y definitorio del lenguaje documental. Con el fin de corroborar esta idea, se ha realizado un desglose pormenorizado de las imágenes usadas en el metraje de los documentales sobre Guerra Civil realizados en España entre 2000 y 2014. Se ha realizado una clasificación de los diferentes tipos que existen y se ha analizado los usos que se les da tanto desde el punto de vista narrativo como desde el punto de vista de su contribución a la fundamentación del tema tratado. Finalmente se ha ahondado en el uso de material proveniente de películas de ficción, y en la elaboración de reconstrucciones, por ser imágenes que cuestionan la verosimilitud del formato. El artículo concluye que los documentales cuentan la historia mediante la generación de una narración que se apoya en las imágenes gracias a su doble y simultánea función documental y narrativa.

Published: July 2024

This study delves into the fascinating history of the destruction of the walls of Jericho as described in the biblical account in the book of Joshua. Over the last century, prominent archaeologists such as Carl Watzinger, John Garstang, Kathleen Kenyon, and Bryant Wood have excavated the site, confirming the existence of the ancient city and its fortified walls during the approximate period of the event.The study explores the possibility that the destruction of Jericho's walls could have a scientific explanation based on natural phenomena. The theory of resonance is proposed, suggesting that sound waves generated by the human shouting might have matched the natural frequency of the walls, weakening their structure and causing their collapse. Resonance calculations indicate that human shouting (300 Hz) was closer to the wall's natural frequency (121.72 Hz) than the trumpets (1400 Hz), implying a higher potential for resonance with the shouting.Despite these plausible explanations, the study emphasizes the historical and religious ambiguity surrounding the event. The biblical account of the conquest of Jericho has been regarded as a miraculous event, and the exact cause of the walls' destruction remains unresolved. This event has left a profound impact on Western culture and religion, with interpretations continuing to be subject to debate and contemplation.The study highlights the significance of dialogue between science and religion. Archaeology and science offer an objective and data-based perspective, while religious beliefs provide spiritual and moral meaning to historical events. The coexistence of these approaches enriches our understanding of the past and cultural heritage.The present work offers a multidisciplinary view that encompasses archaeology, science, and religious beliefs. Although plausible scientific explanations have been proposed, the exact nature of the destruction of Jericho's walls remains a mystery, underscoring the richness of historical and cultural interpretations surrounding this event.
