Biotic Part of the Product Material Footprint: Comparison of Indicators Regarding Their Interpretation and Applicability
Authors: Mostert Clemens , Bringezu Stefan
Published: June 2022

The product material footprint (PMF) represents a central instrument to assess the potential environmental impacts of products and services based on their life-cycle-wide material use. Within the life cycle impact assessment framework, the indicators raw material input (RMI) and total material requirement (TMR) have been used for its calculation, but so far, only abiotic materials have been considered. This research analyses the requirements and indicators for the assessment of the biotic part of the PMF. The central question is whether the indicators RMI biotic and TMR biotic are suitable for this purpose or if they need to be adapted. For comparison, the indicator cumulative raw material demand (CRD) is applied. The indicator concepts of RMI, TMR, and CRD are compared by defining the system boundaries for determining the biotic parts of the footprint. To test the applicability, the production of wheat bread is assessed as a case study. The characterization factors of wheat grains are determined and each of the three indicators is implemented in the software openLCA for use with the ecoinvent database. The results show that RMI biotic and TMR biotic are suitable indicators for the quantification and assessment of the biotic part of the PMF. While CRD abiotic provides the same information as RMI abiotic, both indicators differ regarding the biotic part. The CRD per definition does not consider biotic inputs from agriculture and forestry and thus conveys insufficient information on the used and unused biomass extraction for the product LCA. The ratio of RMI biotic to the net annual increment and TMR biotic to the net primary production could be used for absolute sustainability assessment.

The radio-occultation technique can provide vertical profiles of planetary ionospheric and atmospheric parameters, which merit the planetary-climate and space-weather scientific research so far. The Tianwen-1 one-way single-frequency radio-occultation technique was developed to retrieve Mars ionospheric and atmospheric parameters. The first radio-occultation event observation experiment was conducted on 5 August 2021. The retrieved excess Doppler frequency, bending angle, refractivity, electron density, neutral mass density, pressure and temperature profiles are presented. The Mars ionosphere M1 (M2) layer peak height is at 140 km (105 km) with a peak density of about 3.7 × 1010 el/m3 (5.3 × 1010 el/m3) in the retrieved electron-density profile. A planetary boundary layer (−2.35 km~5 km), a troposphere (temperature decreases with height) and a stratosphere (24 km–40 km) clearly appear in the retrieved temperature profile below 50 km. Results show that Tianwen-1 radio occultation data are scientifically reliable and useful for further Mars climate and space-weather studies.

Published: June 2022

Rapid global warming is catalyzing widespread permafrost degradation in the Arctic, leading to destructive land-surface subsidence that destabilizes and deforms the ground. Consequently, human-built infrastructure constructed upon permafrost is currently at major risk of structural failure. Risk assessment frameworks that attempt to study this issue assume that precise information on the location and extent of infrastructure is known. However, complete, high-quality, uniform geospatial datasets of built infrastructure that are readily available for such scientific studies are lacking. While imagery-enabled mapping can fill this knowledge gap, the small size of individual structures and vast geographical extent of the Arctic necessitate large volumes of very high spatial resolution remote sensing imagery. Transforming this ‘big’ imagery data into ‘science-ready’ information demands highly automated image analysis pipelines driven by advanced computer vision algorithms. Despite this, previous fine resolution studies have been limited to manual digitization of features on locally confined scales. Therefore, this exploratory study serves as the first investigation into fully automated analysis of sub-meter spatial resolution satellite imagery for automated detection of Arctic built infrastructure. We tasked the U-Net, a deep learning-based semantic segmentation model, with classifying different infrastructure types (residential, commercial, public, and industrial buildings, as well as roads) from commercial satellite imagery of Utqiagvik and Prudhoe Bay, Alaska. We also conducted a systematic experiment to understand how image augmentation can impact model performance when labeled training data is limited. When optimal augmentation methods were applied, the U-Net achieved an average F1 score of 0.83. Overall, our experimental findings show that the U-Net-based workflow is a promising method for automated Arctic built infrastructure detection that, combined with existing optimized workflows, such as MAPLE, could be expanded to map a multitude of infrastructure types spanning the pan-Arctic.

Published: June 2022

The evaluation of the ecosystem service value (ESV) and its regionalization toward coordinating ecological protection and socioeconomic development is of great significance. In this study, we developed a classification method based on the Random Forest algorithm and a feature optimization method to identify grassland types. Then, we proposed an approach to quantitatively evaluate the ESV of the grassland ecosystem in Ethiopia, in which net primary production derived from remote sensing was used to evaluate organic matter production value (ESV1), promoting nutrient circulation value (ESV2), and gas regulation value (ESV3), the RUSLE model was used to evaluate soil conservation value (ESV4), and cumulative rainfall was used to calculate water conservation value (ESV5). By integrating the mean ESV under various influencing factors, the zoning map of grassland ecosystem service value was obtained. Our study found that more fine grassland types can be well classified with the overall accuracy of 86.52%. And the classification results are the basis of the ESV analysis. The total ESV of grassland ecosystems was found to be USD 105,221.72 million, of which ESV4 was the highest, accounting for 44.09% of the total ESV. The spatial analysis of ESV showed that the differences were due to the impacts of grassland types, elevation, slope, and rainfall. It was found that the grassland is suitable to grow in the elevation zone between approximately 1000 and 2000 m, and the larger the slope and rainfall are, the greater the mean ESV is. The zoning map was used to conclude that the areas from approximately the fourth to sixth level (only 34.78% of the total grassland area, but 65.94% of the total ESV) have better growth status and development potential. The results provide references and bases to support the local coordination and planning of various grassland resources and form reasonable resource utilization and protection measures.

Published: June 2022

Mare Frigoris is the fifth largest and almost northernmost mare located on the near side of the Moon. Mare Frigoris has an elongated shape, with a length of approximately 1500 km and a width of approximately 200 km, which makes it susceptible to becoming contaminated by the impact ejecta from the nearby highlands. Comparatively speaking, microwave radiometer (MRM) data have good penetration capabilities. Therefore, the MRM data from Chang’e-2 satellite were employed to study the volumetric thermal emission features of basaltic deposits in Mare Frigoris. Combining the MRM data with the basaltic units with FeO and TiO2 abundances identified using the small crater rim and ejecta probing (SCREP) methodology and with the gravity from Gravity Recovery and Interior Laboratory (GRAIL), the four potential conclusions that were obtained are as follows: (1) The MRM data are strongly related to the (FeO + TiO2) abundance of pristine basalts and are less influenced by ejecta contamination; (2) in every quadrant of Mare Frigoris, the (FeO + TiO2) abundance of the basalt decreases with an increase in age; (3) at least in Mare Frigoris, the main influencing factor regarding the brightness temperature remains the (FeO + TiO2) abundance of surface deposits; (4) a warm microwave anomaly was revealed in the western-central and eastern-central areas of Mare Frigoris which has a strong relationship with the positive Bouguer gravity anomaly derived from GRAIL data in terms of spatial distribution. The results are significant in the context of improving our understanding the basaltic igneous rock and thermal evolution of the Moon using MRM data.
Multi-Tone Harmonic Balance Optimization for High-Power Amplifiers through Coarse and Fine Models Based on X-Parameters

Published: June 2022

In this study, we focus on automated optimization design methodologies to concurrently trade off between power gain, output power, efficiency, and linearity specifications in radio frequency (RF) high-power amplifiers (HPAs) through deep neural networks (DNNs). The RF HPAs are highly nonlinear circuits where characterizing an accurate and desired amplitude and phase responses to improve the overall performance is not a straightforward process. For this case, we propose a coarse and fine modeling approach based on firstly modeling the involved transistor and then selecting the best configuration of HAP along with optimizing the involved input and output termination networks through DNNs. In the fine phase, we firstly construct the equivalent modeling of the GaN HEMT transistor by using X-parameters. Then in the coarse phase, we utilize hidden layers of the modeled transistor and replace the HPA’s DNN to model the behavior of the selected HPA by using S-parameters. If the suitable accuracy of HPA modeling is not achieved, the hyperparameters of the fine model are improved and re-evaluated in the HPA model. We call the optimization process coarse and fine modeling since the evaluation process is performed from S-parameters to X-parameters. This stage of optimization can ensure modeling the nonlinear HPA design that includes a high number of parameters in an effective way. Furthermore, for accelerating the optimization process, we use the classification DNN for selecting the best topology of HPA for modeling the most suitable configuration at the coarse phase. The proposed modeling strategy results in relatively highly accurate HPA designs that generate post-layouts automatically, where multi-tone harmonic balance specifications are optimized once together without any human interruptions. To validate the modeling approach and optimization process, a 10 W HPA is simulated and measured in the operational frequency band of 1.8 GHz to 2.2 GHz, i.e., the L-band. The measurement results demonstrate a drain efficiency higher than 54% and linear gain performance more than 12.5 dB, with better than 50 dBc adjacent channel power ratio (ACPR) after DPD.

Published: June 2022

This paper presents the implementation of a multiplexed analog readout electronics system that can achieve single-electron counting using Skipper-CCDs with non-destructive readout. The proposed system allows the best performance of the sensors to be maintained, with sub-electron noise-level operation, while maintaining low-bandwidth data transfer, a minimum number of analog-to-digital converters (ADC) and low disk storage requirement with zero added multiplexing time, even for the simultaneous operation of thousands of channels. These features are possible with a combination of analog charge pile-up, sample and hold circuits and analog multiplexing. The implementation also aims to use the minimum number of components in circuits to keep compatibility with high-channel-density experiments using Skipper-CCDs for low-threshold particle detection applications. Performance details and experimental results using a sensor with 16 output stages are presented along with a review of the circuit design considerations.

Authors: Guo Jian , Wang Jun , Zhu Baikang , Hong Bingyuan , Li Cuicui , He Jianhui
Published: June 2022

Oil depots in the coastal areas of China are prone to disasters caused by heavy rain due to the monsoon climate. Studies focusing on heavy rainfall vulnerability in coastal oil depots are limited. Therefore, we evaluated the safety of oil depots based on four factors in this study: personnel, equipment and facility, environment, and resilience. Complex networks, analytic hierarchy processes, and information entropy theory were used to establish an evaluation index system including four first-level indicators, nine second-level indicators, and 40 third-level indicators. Scores of 40 evaluation indicators were taken as the input, a vulnerability level of oil depots affected by heavy rain was gained as the output, and results were presented visually (different warning levels distinguished by color) to help oil depot enterprises improve their safety performance under extreme weather conditions.
Multi-Scenario Simulation Analysis of Land Use Impacts on Habitat Quality in Tianjin Based on the PLUS Model Coupled with the InVEST Model
Authors: Li Xiang , Liu Zhaoshun , Li Shujie , Li Yingxue
Published: June 2022

Land use change is an important cause of habitat quality change. In order to reveal the impact of urban land use change on habitat quality, and to explore sustainable development planning, this paper uses the city of Tianjin, China, as a case study. Based on land use data from 2000, 2010, and 2020, the PLUS model was first used to predict land use in 2030 under three scenarios, and the InVEST model was then used to assess habitat quality from 2000 to 2030. This study showed that habitat quality was highly correlated with land use change. The rapid expansion of construction land was the main reason for the year-by-year decline in habitat quality. From 2000 to 2030, habitat quality in Tianjin declined year-by-year according to the average habitat quality values for 2030 for the three scenarios: the Ecological Protection Scenario (EPS) > Natural Development Scenario (NPS) > Economic Construction Scenario (ECS). In the EPS, habitat quality will deteriorate and improve. It would be ecologically beneficial to continue to work on the revegetation of the Jizhou area. In the ECS, habitat quality will decline sharply. In Tianjin, urbanization will continue to accelerate. This is a threat to the sustainable development of the city.

Published: June 2022

Global change, population growth, and urbanization have been exerting a severe influence on the environment, including the social system and ecosystem. To find solutions based on nature, clarifying the complicated mechanisms and feedback among land use/land cover changes, ecosystem services, and human well-being, is increasingly crucial. However, the in-depth linkages among these three elements have not been clearly and systematically illustrated, present research paths have not been summarized well, and the future research trends on this topic have not been reasonably discussed. In this sense, the purpose of this paper is to provide an insight into how land use/land cover changes, ecosystem services, and human well-being are linked, as well as their relationships, interacting ways, applications in solving ecological and socioeconomic problems, and to reveal their future research trends. Here, we use a systematic literature review of the peer-reviewed literature to conclude the state of the art and the progress, emphasize the hotspot, and reveal the future trend of the nexus among the three aspects. Results show that (1) ecosystem services are generally altered by the changes in land use type, spatial pattern, and intensity; (2) the nexus among land use change, ecosystem services, and human well-being is usually used for supporting poverty alleviation, ecosystem health, biodiversity conservation, and sustainable development; (3) future research on land use/land cover changes, ecosystem services, and human well-being should mainly focus on strengthening multiscale correlation, driving force analysis, the correlation among different group characteristics, land use types and ecosystem service preferences, and the impact of climate change on ecosystem services and human well-being. This study provides an enhanced understanding of the nexus among the three aspects and a reference for future studies to mitigate the relevant problems.

Forest fires destroy productive land throughout the world. In Brazil, mainly the Northeast of Brazil (NEB) is strongly affected by forest fires and bush fires. Similarly, there is no adequate study of long-term data from ground and satellite-based estimation of fire foci in NEB. The objectives of this study are: (i) to evaluate the spatiotemporal estimation of fires in NEB biomes via environmental satellites during the long term over 1998–2018, and (ii) to characterize the environmental degradation in the NEB biomes via orbital products during 1998–2018, obtained from the Burn Database (BDQueimadas) for 1794 municipalities. The spatiotemporal variation is estimated statistically (descriptive, exploratory and multivariate statistics) from the Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI) and Standardized Precipitation Index (SPI) through the Climate Hazards Group InfraRed Precipitation Station (CHIRPS). Moreover, we identify 10 homogeneous groups of fire foci (G1–G10) with a total variance of 76.5%. The G1 group is the most extended group, along with the G2 group, the exception being the G3 group. Similarly, the G4–G10 groups have a high percentage of hotspots, with more values in the municipality of Grajaú, which belongs to the agricultural consortium. The gradient of fire foci from the coast to the interior of the NEB is directly associated with land use/land cover (LULC) changes, where the sparse vegetation category and areas without vegetation are mainly involved. The Caatinga and Cerrado biomes lose vegetation, unlike the Amazon and Atlantic Forest biomes. The fires detected in the Cerrado and Atlantic Forest biomes are the result of agricultural consortia. Additionally, the two periods 2003–2006 and 2013–2018 show periods of severe and prolonged drought due to the action of El Niño.
What Is the Link between Strategic Innovation and Organizational Sustainability? Historical Review and Bibliometric Analytics
Authors: Yin Chi-Yen , Chang Hsiao-Hsin
Published: June 2022

The academic and practical are very acquainted with both strategic innovation (SI) and organizational sustainability (OS) at present, but a literature review revealed that there are few studies discussing the correlation between SI and OS in these two subjects. This study attempts to identify and classify these articles (SI and OS) in publications. Seven spotlights are noted in this paper in terms of the (1) published year, (2) citation report, (3) country/territory, (4) affiliation name, (5) document type, (6) Web of Science (WoS) categories, and (7) publication titles. A total of 125 (SI = 70 and OS = 55) articles were retrieved from the Social Sciences Citation Index (Web of Science). We applied a bibliometric analytics technique to depict a panorama among the core journals, document characteristics, and research trends over thirty years (1991–2021) by setting the article titled as “strategic innovation” or “organizational sustainability” in the SSCI electronic database. In this study, Bradford’s law was necessarily adapted to examine how many journal papers were frequently cited. These journals could be an exceptional reference for rising researchers to swiftly detect relevant information. The Kolmogorov–Smirnov (abbreviation: K–S) test was also conducted to survey whether the author’s productivity complied with Lotka’s law. The benchmarks were broadened to evaluate the capability and academic standing of different authors in a certain subject area. The results unveiled that comparing the expansionary scope of SI and OS research can fit well with industry, government, academia, and research for their various requirements, functions, and schemes. According to the above analysis, these findings simultaneously constitute an adequate preparation and represent a blueprint for those who need to refer to the collections to formulate an appropriate research platform in the near future.

Published: June 2022

Hydropower is the largest renewable source of electricity generation, the carbon emissions of which have attracted a lot attention. However, the system boundaries of existing studies are either incomplete or inaccurate. Therefore, this study provides a systems accounting framework for evaluating both the direct and indirect carbon emissions from a hydropower plant. It is based on the hybrid method as a combination of the process analysis and the input-output analysis. To demonstrate the framework, a case study for a typical pumped storage hydropower plant (NPSHP) is carried out. The total carbon emissions are estimated as 5828.39 kt in the life-cycle of the case system. The end-of-use stage causes the largest carbon emissions (38.4%), followed by the construction stage (34.5%), the operation stage (25.6%), and the preparation stage (1.5%). The direct carbon emissions are mainly released from sediments in the end-of-use stage and the surface of reservoirs in the operation stage (94.8%). The indirect carbon emissions are 2.8 times higher than the direct carbon emissions. The material, machinery, energy, and service inputs respectively account for 7.1%, 14.7%, 15.9%, and 62.3% of the total indirect carbon emissions by the case system. The indicator of EGOC (electricity generation on carbon emission) for the NPSHP is calculated as 26.06 g CO2-eq./kWh, which is lower than that of most other power plants.
On the Exiting Patterns of Multivariate Renewal-Reward Processes with an Application to Stochastic Networks
Authors: White Ryan T.
Published: June 2022

This article is a study of vector-valued renewal-reward processes on Rd. The jumps of the process are assumed to be independent and identically distributed nonnegative random vectors with mutually dependent components, each of which may be either discrete or continuous (or a mixture of discrete and continuous components). Each component of the process has a fixed threshold. Operational calculus techniques and symmetries with respect to permutations are used to find a general result for the probability of an arbitrary weak ordering of threshold crossings. The analytic and numerical tractability of the result are demonstrated by an application to the reliability of stochastic networks and some other special cases. Results are shown to agree with empirical probabilities generated through simulation of the process.
Current Concepts in Pediatric Pelvic Ring Fractures: A Narrative Review
Authors: Aprato Alessandro , Giudice Carmelo , Bedino Paolo , Audisio Andrea , Massè Alessandro
Published: June 2022

Trauma is still the leading cause of death in children. Post mortem studies have shown a high incidence and a high rate of deaths related to pelvic fractures and associated injuries. The pelvic ring in children has characteristics that differentiate it from the adult. The bone tissue is more elastic and is covered with a thick periosteum. Elasticity mainly translates into plastic deformity when it is impacted. Overall, lesions tend to be more stable as the relatively thick periosteum limits bone breakdown. As a result of this elasticity, the intrapelvic organs are more vulnerable and injuries can occur in the absence of fractures. High energy is required to produce a fracture and this energy can be transferred to the pelvic organs. Minimally displaced fractures may be the result of high energy trauma with a significant risk of further intrapelvic and intra-abdominal injury. This leads to a relatively high incidence of pelvic and abdominal organ injuries associated with stable fractures. A complete lesion of the pelvic ring anteriorly or posteriorly or a complex pelvic lesion is a high risk factor for morbidity and mortality. Treatment in the pediatric patient with a pelvic fracture has historically been guided by concepts that have become established in adults. The main parameters in the decision making process are hemodynamic stability and the degree of mechanical instability of the pelvis. The purpose of this review is to report current knowledge on pelvic ring fractures with a particular focus on their management and treatment.

Published: June 2022

Experimental results on scour at abutments under unsteady clear water flow condition are presented. Three shapes of short abutments (abutment length/upstream flow depth < 1) were tested, namely, rectangular/vertical wall, semi-circular, and trapezoidal/45° wing-wall abutments embedded in uniform sands of two sizes having d50 = 0.52 mm and 0.712 mm. The unsteadiness of the flow is considered in the form flood hydrographs of three forms, namely: advanced flood hydrograph (Type I), symmetrical flood hydrograph (Type II), and delayed flood hydrograph (Type III) with the flow maintained at clear water condition in all cases. The experimental findings are used to represent the influence of various parameters on scour depth at bridge abutments. It was observed that the scour depth at rectangular abutments is greater than that at trapezoidal and semi-circular abutments. The scour depths at abutments embedded in finer sediments are greater than those in coarser sediments. In addition, based on the study of effect of three flood hydrographs, it was noticed that the delayed flood hydrograph yields greater scour depth as compared to the other two cases. Further, based on the method of superposition and the correction of shape factor, a semi-empirical model using dimensionless parameters is proposed to compute the temporal evolution of scour depth at abutments under unsteady clear water conditions. The parameters used in this model include flow shallowness, flow intensity, sediment coarseness, and time factor. It was found that the proposed model corresponds well with the data of time-dependent scour depth in uniform sediments obtained from the present experiments (unsteady flows) and reported by different investigators (steady flows).
El papel de la Economía Circular en el cumplimiento del Objetivo de Desarrollo Sostenible 11: ciudades y comunidades sostenibles
Authors: Molinillo Sergio
Published: June 2022

El ritmo de vida actual genera no pocos desafíos para las sociedades modernas, así como para la preservación de la biodiversidad y el futuro del planeta. El aumento de la población y su presión sobre los recursos naturales, los ineficientes modelos de producción y consumo, la emisión de gases de efecto invernadero (GEI) que fomentan el cambio climático, son problemas que se han trasladado a las ciudades, a los que se suman retos como la exclusión social y la desigualdad de oportunidades. Desde los organismos internacionales se toma conciencia de todo esto y, en el marco de los Objetivos de Desarrollo Sostenible (ODS) se incorpora el ODS 11, Ciudades y Comunidades Sostenibles, como estrategia para hacer frente a dichos desafíos. En los últimos años, diferentes políticas gubernamentales han introducido algunas medidas para lograr la consecución de cada una de las metas de este ODS, entre las que destacan las relacionadas con la economía circular; un modelo que aún se encuentra en los inicios de su implementación en las ciudades del mundo, pero que ya presenta efectos positivos, lo cual supone una oportunidad para impulsar el desarrollo sostenible en las zonas urbanas.

Background: Parotid gland tumors account for 80% of all salivary gland neoplasms, but 80% of parotid tumors are benign. In the presence of a parotid mass, a physical examination is the first diagnostic tool and, in most cases, it guides the clinician in the appropriate direction. A fine needle aspiration biopsy (FNA) has been indicated by several authors for the diagnostic work-up. Ultrasonography, computed tomography, and/ or magnetic resonance imaging are useful complementary studies for proper surgical planning. Objective: Study clinical, paraclinical features of parotid gland tumor surgery. Materials and Methods: 31 patients with parotid gland tumor who were examined at Hue University of Medicine and Pharmacy Hospital from June
2019 to June 2020 were recorded about clinical, paraclinical of tumour. Results: Parotid salivary gland tumors in men account for 54.8, the mean age of patients was 53.7±12.3. Majority of the parotid gland tumor size in ultrasound were between 2 and 4 cm (67.7%), homogenous (67.7%). Majority of the parotid gland tumor size in CT scanner encountered were between 2 and 4 cm (67.7%), homogenous (61.3%) and in the superficial lobe (96.8). Preoperative fine needle aspiration biopsy (FNA) results showed 35.5% pleomorphic adenoma. Conclusion: FNA - Fine Needle Aspiration, Ultrasound and CT scanner were very valuable for diagnosis.

ROLE OF SOME CLINICAL SCALES IN ASSESSMENT OF OUTCOMES IN PATIENTS WITH INTRACEREBRAL HAEMORRHAGE
Authors: Nguyen Dinh Toan
Published: June 2022

Background: Intracerebral haemorrhage (ICH) accounts for the highest of hospital mortality of all stroke types, outcome is favourable in about 12-39% of patients. There are many clinical prognostic evaluation scales such as NIHSS, Glasgow, ICH, mICH-A, mICH-B, FUNC and more recently, the ESSEN scale studied by Weimar et al. in 2006. Despite several existing outcome prediction models for ICH, most of them to predict the hospital mortality but only some models for prediction the complete outcome after 100 days in patients with ICH. Objectives: (1) To survey the characteristics of clinical scales in patients with cerebral hemorrhage; (2) To evaluate the prognostic value of the clinical scale with the outcome of patients with
cerebral hemorrhage after 100 days. Subject and methods: Cross‐sectional descriptive study on 120 patients with spontaneous intracerebral haemorrhage at Hue Central Hospital from 06/2019-02/2020. The patients were assessed on the Essen ICH (include: age, NIHSS, NIHSS LOC) Glasgow, ICH, mICH and other factor on 24 hours onset and follow up of 100 days. Statistical analysis was carried out with the program package SPSS version 20.0. Logistic was used to determine of independent risque factors and scales value was determined by ROC curve.

O Programa Nacional Biblioteca da Escola, iniciado em 1997, apoia a promoção da cultura, estimulando a leitura entre alunos/professores, através da distribuição de obras literárias e de pesquisa para constituição de acervo nas bibliotecas escolares de todo o país, por compreendê-las como o espaço de gerenciamento das obras e de favorecimento de acesso à leitura, contribuindo para a formação de leitores. Diante disso, este texto tem por objetivo apresentar uma reflexão sobre as políticas de incentivo à leitura, especificamente o PNBE, com foco nos espaços escolares de leitura. Para tanto, desenvolve-se um estudo descritivo, com uma abordagem qualitativa, a partir dos documentos do PNBE e da BNCC, de modo a dar visibilidade aos (des)equilíbrios das ações de incentivo à leitura no Brasil, nos últimos anos.

O baixo aproveitamento dos alunos das escolas públicas do município de Morrinhos (GO), no Índice de Desenvolvimento da Educação Básica (Ideb), desperta a atenção para os problemas relacionados à formação do leitor na educação infantil. Neste contexto, analisamos as práticas de leitura nas salas das séries iniciais do Ensino Fundamental do município, a partir de algumas questões: O que são mediadores de leitura? Quem desempenha esse papel nos diversos âmbitos em que o aprendiz de leitor circula? O que são práticas de mediação de leitura? Inicialmente, assistimos 25 aulas a fim de verificar as práticas de leitura implementadas, e observamos que as crianças manifestam grande interesse pela leitura, escrita e que realizam várias hipóteses de trato com essas duas atividades. Esse engajamento vai paulatinamente diminuindo conforme vai aumentando o grau de escolaridade desses alunos. Ademais, as avaliações apresentaram dificuldades com relação a compreensão básica da leitura e possibilidades da escrita.

A Educação Infantil é uma fase em que, geralmente, a linguagem oral é desenvolvida de maneira mais intensa e a leitura literária pode se constituir como uma proposta de trabalho em que a criança é colocada diante das múltiplas linguagens, promovendo aprendizagens fundamentais ao desenvolvimento infantil. O objetivo deste trabalho é refletir sobre a leitura como possibilidade de ampliação dos gêneros orais na Educação Infantil. Este estudo parte da análise de dados de uma pesquisa de mestrado realizada por meio da observação participante com crianças de cinco anos da Educação Infantil e sua professora. Tem como embasamento a Teoria Histórico-Cultural, formulada por Vigotski e os pressupostos sobre linguagem e gêneros discursivos de Bakhtin (2011). Os resultados mostram que a leitura literária nas rodas de leitura se constitui como situação, espaço e tempo frutíferos para a concretização das relações entre professora e crianças, impulsionando aprendizagens e promovendo desenvolvimento da linguagem oral.
UM INTELECTUAL ESQUECIDO: PRÁTICAS DE LEITURA DE FRANCISCO LINS
Authors: Santos Daise Silva dos
Published: June 2022

Apresentar alguns indícios sobre as práticas de leitura do professor, jornalista e poeta mineiro Francisco Lins (1866-1933) é o objetivo deste artigo. Apesar de todo o esquecimento que paira hoje sobre o nome desse intelectual, houve um tempo em que ele foi bastante lido por muitos dos que folheavam os grandes periódicos do final do século XIX e início do século XX. Sejam por suas poesias, crônicas, cartas ou traduções, Francisco Lins fez nome na imprensa e nas letras, por vezes assinando com diferentes pseudônimos. Foi membro fundador da Academia Mineira de Letras (AML) e publicou livros, em sua maioria de poesias. No campo da educação, assumiu diversos cargos e por duas vezes foi enviado em comissão de viagem à Europa para estudar novos modelos e métodos educativos. A partir de indícios deixados em seus textos, como nas críticas literárias de sua autoria publicadas nos jornais e outras fontes que nos permitem conhecer mais sobre esse intelectual, buscamos apresentar suas preferências de leitura. Para tanto, recorremos aos estudos de Chartier (1990; 1995; 1998), entre outros autores que pesquisam os livros e a leitura. Entendemos que com isso, além de lançar luz sobre esse importante acadêmico já esquecido, contribuímos para os estudos dos intelectuais e das práticas letradas.

DO BURBURINHO CITADINO AO ISOLAMENTO E SEUS SILÊNCIOS: REFLEXÕES SOBRE LITERATURA E ESPAÇO URBANO CORONAVÍRUS
Authors: Sopran Fátima Leonor , Faria Wanderley Marta Maria Silva de
Published: June 2022

Esse ensaio tem como objetivo refletir a respeito da relação entre literatura e espaço urbano. Abordamos a situação das cidades com traços que apontam características urbanas contemporâneas, como a atual pandemia. O ensaio busca discutir literatura e espaço urbano no atual momento da pandemia de Coronavírus. As cidades tornam-se grandes protagonistas dos acontecimentos cotidianos, há um elo entre a literatura e os espaços reais. A pandemia abala os lugares e possibilita a escrita de um cotidiano citadino abatido pelo vírus. A discussão sobre pandemia, literatura e espaço urbano dialoga com os romances A Peste, de Camus (1997) e o Ensaio sobre a Cegueira, de Saramago (1995), por ambas tratarem de pandemia e da artificialidade vivida pelo ser humano, bem como instiga uma possível reflexão que deve ser feita nesse sentido. As obras constituem uma potência para tratar do registro de uma história cultural urbana das cidades.
