ℒ1 adaptive controller of VEGA Launcher subject to flexible modes
Authors: NAJI Naji Anees Muqdad , STOICA Adrian-Mihail
Published: December 2024

Flexible launch vehicle modes contribute to the deterioration of its stability performance. For this reason, their influence must be considered when designing and validating appropriate solutions for its automatic control system. The first three bending modes are the most relevant for control system design and analysis. Next, considerations regarding the elastic modes of the Vega actuator, used in the simulations performed throughout this study, are presented. The IMU (Inertial Measurement Unit) measurements providing attitude angles and angular rates are strongly corrupted by the local elastic deformations resulting from structural flexibility. These measurements are fed back to the TVC (Thrust Vector Control) system which controls the pitch and the yaw motion of the vehicle. The design methodology for this control system is based on an ℒ1 adaptive technique incorporating a Butterworth filter guarantees good stability performances for wide variations of the launcher’s dynamics parameters.
Simulation and assessment of spaceborne hybrid Doppler wind lidar, Part 1: the spaceborne two-beam stepping direct detection Doppler wind lidar
Authors: Long Wenrui , Dai Guangyao , Wu Songhua , Sun Kangwen , Zhai Xiaochun , Xu Na , Shang Jian , HU XIUQING
Published: December 2024

Accurately measuring wind field is crucial for weather forecasting, climate and meteorological research, aeronautical flights and wind resource exploitation. Spaceborne Doppler wind lidar has become an important instrument for observing the vertical profile of the global wind field, with the successful operation of Aeolus. The third generation of FengYun polar-orbiting meteorological satellites are initially designed to develop a dual-system Doppler wind measurement lidar technology programme that integrates direct and coherent detection lidar, making full use of the observational advantages of the two methods to detect the global wind field with high resolution. As the first part of a series of simulation demonstration research, this paper presents an end-to-end simulation model for the spaceborne direct detection Doppler lidar system, which is designed to meet the three-dimensional wind detection requirements in the middle and upper troposphere and the lower stratosphere. The simulated spaceborne lidar will work at 355 nm and will deploy the dual-edge detection technique based on parallel-designed Fabry–Pérot filters for the frequency discrimination. Referring to the application experience of Aeolus simulator in demonstration and evaluation, the direct detection lidar simulation model developed in this study can be used to simulate the observation performance of wind field and develop retrieval algorithms. And a gridded global atmospheric parameter model is constructed with usage of the Aerosol and Carbon Detection Lidar (ACDL) in-orbit measurements and meteorological reanalysis data, to provide as realistic an atmospheric background field as possible for the simulation model. In order to achieve the effective observation of horizontal wind speed and direction, this paper proposes a two-beam stepping detection mode and optimizes the angle design of the observation beam to achieve a better detection response for both meridional wind component and zonal wind component. By using this spaceborne dual-beam direct detection lidar global simulation, taking the global wind field simulation at the altitude of 10 km in July 2022 as an example, the modelled horizontal wind speed error is less than 2m/s and the wind direction error is less than 8° in most areas.
CPLLM: Clinical prediction with large language models
Authors: Ben Shoham Ofir , Rappoport Nadav
Published: December 2024

We present Clinical Prediction with Large Language Models (CPLLM), a method that involves fine-tuning a pre-trained Large Language Model (LLM) for predicting clinical disease and readmission. We utilized quantization and fine-tuned the LLM using prompts. For diagnostic predictions, we predicted whether patients would be diagnosed with a target disease during their next visit or in the subsequent diagnosis, leveraging their historical medical records. We compared our results to various baselines, including Retain and Med-BERT, the latter of which is the current state-of-the-art model for disease prediction using temporal structured EHR data. In addition, we also evaluated CPLLM’s utility in predicting hospital readmission and compared our method’s performance with benchmark baselines. Our experiments ultimately revealed that our proposed method, CPLLM, surpasses all the tested models in terms of PR-AUC and ROC-AUC metrics, providing state-of-the-art performance as a tool for predicting disease diagnosis and patient hospital readmission without requiring pre-training on medical data. Such a method can be easily implemented and integrated into the clinical workflow to help care providers plan next steps for their patients.

Published: December 2024

A new round of monkeypox virus has emerged in the United Kingdom since July 2022 and rapidly swept the world. Currently, despite numerous research groups are studying this virus and seeking effective treatments, the information on the open reading frame, inhibitors, and potential targets of monkeypox has not been updated in time, and the comprehension of monkeypox target ligand interactions remains a key challenge. Here, we first summarized and improved the open reading frame information of monkeypox, constructed the monkeypox inhibitor library and potential targets library by database research as well as literature search, combined with advanced protein modeling technologies (Sequence-based and AI algorithms-based homology modeling). In addition, we build monkeypox virus Docking Server, a web server to predict the binding mode between targets and substrate. The open reading frame information, monkeypox inhibitor library, and monkeypox potential targets library are used as the initial files for server docking, providing free interactive tools for predicting ligand interactions of monkeypox targets, potential drug screening, and potential targets search. In addition, the update of the three databases can also effectively promote the study of monkeypox drug inhibition mechanism and provide theoretical guidance for the development of drugs for monkeypox.
Workout at a virtual gym: Surrounding avatar’s motion speed and exercise intensity effect on the user’s time perception
Authors: Ke Bingcheng , Wang Tzu-Yang , Yuizono Takaya , Kanai Hideaki
Published: December 2024

This study explored the relationship between surrounding avatars and time perception in a virtual reality (VR) gymnasium. Previous research has highlighted that motion speed and exercise intensity significantly influence time perception. In VR, time perception is shaped by various factors, such as an avatar’s embodiment at different levels. However, the specific effects of the surrounding avatar on time perception in a VR gymnasium context remain unclear. Thus, this study focuses on two key attributes of the surrounding avatar: (1) motion speeds and (2) exercise intensity. Participants in a VR gymnasium either rode a stationary bike or sat on one while observing avatars performing exercises in the virtual environment(VE). They were then asked to estimate the duration judgment and the feeling of the passage of time for each task. The results revealed that when the surrounding avatars exercised at a faster motion speed, participants perceived the duration of time as longer and felt that time passed more quickly. Additionally, high-intensity exercise led participants to perceive the passage of time as faster.
SUMO-targeted Ubiquitin Ligases as crucial mediators of protein homeostasis in Candida glabrata
Authors: Gupta Dipika , Shukla Renu , Mishra Krishnaveni
Published: December 2024

Candida glabrata is an opportunistic human pathogen, capable of causing severe systemic infections that are often resistant to standard antifungal treatments. To understand the importance of protein SUMOylation in the physiology and pathogenesis of C. glabrata, we earlier identified the components of SUMOylation pathway and demonstrated that the deSUMOylase CgUlp2 is essential for pathogenesis. In this work we show that the CgUlp2 is essential to maintain protein homeostasis via the SUMO-targeted ubiquitin ligase pathway. The dual loss of deSUMOylase and specific ubiquitin ligase, CgSlx8, results in heightened protein degradation, rendering the cells vulnerable to various stressors. This degradation affects crucial processes such as purine biosynthesis and compromises mitochondrial function in the mutants. Importantly, the absence of these ubiquitin ligases impedes the proliferation of C. glabrata in macrophages. These findings underscore the significance of SUMOylation and SUMO-mediated protein homeostasis as pivotal regulators of C. glabrata physiology and capacity to survive in host cells. Understanding these mechanisms could pave the way for the development of effective antifungal treatments.
An (incomplete) manifesto for gardening as an EcoSomatic practice
Authors: Hudson Polly
Published: December 2024

This primarily visual and poetic contribution: part manifesto, part rally call for environmental and EcoSomatic action and part memoir, shares some of the work that I have been investigating in embodiment and in permaculture. It is part of ongoing practice as a gardener and dancer, a long-term research endeavour on an inner-city urban allotment in the United Kingdom, titled ‘And So We Sow’, which has been developing since 2017. It features images created in collaboration with the photographer Ming de Nasty at my plot in the summer of 2022. The work draws on principles from Releasing dance practices, particularly Skinner Releasing Technique, from organic gardening techniques and from wider embodied engagement. It has various strands underpinned by a curiosity about how we inhabit our inner and outer landscapes simultaneously. Currently, it reflects on my working-class roots and on women’s labour of the body and on the land.
The imperative of the present: Improvisation and the ageing body
Authors: Millard Olivia , Hunter Kate
Published: December 2024

This article examines an interdisciplinary improvisation practice that brings together dancer Olivia Millard and theatre-maker Kate Hunter. Drawing on their performance work, Audio Logical, the authors unfold their separate and interwoven practices as they respond, react, move and travel together through the crossovers and meeting points in the genealogies of their combined 50-year performance history. This immersive practice has brought considerations to the fore of sustaining a practice; what does it mean to build a body of work – and a body? How do we sustain an embodied practice now and into the future? Audio Logical engages with the imperative of the present while contemplating past experiences and embodied histories. The artists also acknowledge their ageing female bodies unapologetically. Rather than representing a loss of youth, the elder body is proposed as a site of revolutionary potential.
Moving with uncertainties: The development of Six Positions on Uncertainty
Authors: Popkin Lionel
Published: December 2024

Between March and June of 2020, in the first round of COVID-19 lockdowns, I made Six Positions on Uncertainty, a six-channel movement video from scores that grew out of my wrestling with the fear, confusion and isolation that lockdown brought, while also thinking through the myriad of influences in my movement training history. With the world at a precipice, I asked, how do I want to move now? Not how have I been trained to move or approach moving, but what aspects of those trainings do I still want to embrace, and which would I like to jettison? In this article I discuss how I built the structure and material for the piece, paying particular attention to the many sources that informed its development, moving out of universalist ‘theories of’ or ‘proposals of’ a body and into the individual ‘practice’ put forward by my complicated and multifaceted history.
How to open up: Factors influencing receptivity to ecosomatic education
Authors: Eriksson Ester
Published: December 2024

Concerns about redundancy of ecosomatic education due to its niche nature or inaccessibility may be overestimated. This study interviewed ecosomatics students to examine which factors are involved in piquing interest in this form of education and knowledge production. Findings can inform how ecosomatic education can best be promoted and organized to attract under-reached demographics. Receptivity to ecosomatic education does not require previous interest in either somatics or the environment, but can be driven by other incentives, such as interest in adjacent activities, academic credit rewards, physical health improvement, financial access or recommendations, suggesting that how programmes are institutionally validated and presented as beneficial to the student has implications for reach and impact. This study offers guidance on relevant factors and challenge assumptions about who engages with ecosomatics.
A educação diferenciada e a formação de professores que atuam em comunidades caiçaras: ação fundamental para a redução de riscos e desastres
Authors: Cruz Marina Alves Novaes e , Freitas Leonardo Esteves de , Bernardo Loureiro Carlos Frederico
Published: December 2024

Em Paraty/RJ, os territórios das comunidades caiçaras são cobiçados pelo capital, o que tem gerado desterritotialização e impactos ambientais. O papel dessas comunidades em redução de riscos e desastres (RRD) pôde ser percebido em 2022, quando ocorreram as maiores chuvas já registradas na região. O número de 23 mortes foi menor que o observado em eventos marcados por chuvas menos intensas. Uma das explicações é que a chuva se concentrou em territórios tradicionais, onde há predomínio de florestas, além da menor densidade de moradias. Garantir a permanência das comunidades caiçaras em seus territórios é trabalhar pela RRD. A permanência passa pela construção de uma Educação Escolar Diferenciada que valorize os modos de vida dessas comunidades e fortaleça sua luta por direitos territoriais. Esse processo é o cerne de um programa de formação docente e reorientação curricular realizado em escolas públicas situadas em comunidades caiçaras. Os resultados têm indicado o fortalecimento da cultura caiçara nas escolas e nas comunidades, favorecendo a luta dessas comunidades pela permanência em seus territórios.

Published: December 2024

Este trabalho discute as contribuições da educação geográfica para a análise da espacialidade da vulnerabilidade de gênero entre jovens estudantes de uma escola da rede pública, em São João del-Rei, Brasil. Para isso, desenvolveu-se um percurso educativo geográfico, intitulado 'Geoficinas’, que leva em consideração as geografias, espacialidades e o cotidiano das alunas. Esse percurso educativo fundamenta-se nos princípios do raciocínio geográfico e nas contribuições das epistemologias das Geografias Feministas. Por meio das metodologias de pesquisa-ação e leitura dos espaços geossimbólicos foram analisadas as falas, percepções, vivências e narrativas das jovens estudantes em relação à dimensão espacial do risco social decorrente da desigualdade de gênero. Os resultados revelam que a maioria das estudantes já sofreu ou sofre violência de gênero e que elas demonstram-se engajadas em ações de segurança e prevenção. Esses fatos destacam a importância de se considerar o espaço da escola como lócus onde se dialoga e se reproduz diversos elementos que costuram a sociedade.
Experimental dynamic analysis of the footbridge across Jizera River in Mladá Boleslav
Authors: Čáp Miroslav , Šána Vladimír , Polák Michal , Plachý Tomáš
Published: December 2024

The text of this submitted paper is devoted to the experimental dynamic analysis of the newly designed footbridge across the Jizera River in Mladá Boleslav. Theoretical modal analysis has shown potential risk that some of the natural frequencies of the bridge deck will belong to the range which is typical for pacing frequencies induced by pedestrians. The resonance behaviour of this structure should be reduced by Tuned Mass Dampers (TMD), which would be tuned for separate natural frequencies of this structure. Therefore, the experimental dynamic analysis was performed on the footbridge in order to assess the effectiveness of installed TMDs. The experiment was divided into two stages, the first one was realized at the footbridge when TMDs were not yet installed, and the second one was carried out on the footbridge with installed and activated TMDs. Moreover, the authors have performed an experimental modal analysis in order to verify the aptness of the computational model and its results.
Effect of geometry on homogenised properties of selected auxetic metamaterials
Authors: Jošková Nataša , Doškář Martin
Published: December 2024

Our study investigates the influence of geometrical parameters of two types of auxetic metamaterials on their effective properties. In particular, we focus on three-dimensional lattice structures, which we represent with discrete beam models of their respective Periodic Unit Cells (PUCs). Limiting the scope of the study to linear elasticity, we compute the effective response of PUCs by plugging the kinematic ansatz of the first-order numerical homogenisation into the strain energy expression arising from the Direct Stiffness Method and minimising the energy with respect to the periodic fluctuation field. The obtained effective stiffness matrices are post-processed to arrive at elastic parameters as Poisson’s ratios coefficients, that are reported in different directions with respect to the key geometrical parameters.
The concept of fractured rock-mass modeling using DFN-based statistical volume elements
Authors: Lebeda Martin , Kabele Petr
Published: December 2024

The overall mechanical response of a fractured rock mass is, to a large extent, affected by naturally occurring fractures that exhibit sizes from millimeters to kilometers. Thus, in analysis of underground structures, such as tunnels, it is required that the fractures’ influence on the stress and deformation state in the vicinity of the structure is taken into account. In the present work, we examine the applicability of the statistical volume element (SVE) approach to determining the apparent stiffness tensor of an equivalent continuum representation of the fractured rock, which is then used in the framework of the finite element method. The equivalent continuum properties are determined by volume-averaging the effect of individual fractures that intersect the SVE, while the fractures are represented using the “parallel plate model”. Stochastically generated discrete fracture networks are used to represent the fractures’ geometry. Presently, we solve the problem linearly for an incremental change of the stress state. An application of the concept is demonstrated on simulation of tunnel excavation.
A simplified design of a concrete sandwich structure containing a reinforcing rib
Authors: Macháček Jan , Kafková Eliška , Kabíčková Věra , Vlach Tomáš
Published: December 2024

This article presents the use of a strut and tie analogy for modelling the behaviour of a concrete sandwich structure, which is formed by thin outer concrete layers made of high-performance concrete and reinforcing ribs. The beams transmitting shear are made of a rigid material with low thermal conductivity (Purenit) in combination with a carbon fibre reinforced polymer. The purpose of these ribs is to ensure reliable shear interaction of the outer concrete layers regardless of the thermal insulation of the sandwich structure. A simplified model using the truss analogy in the Scia Engineer software was used for the design of this structure. Furthermore, this design was verified experimentally on a section of the sandwich panel where the feasibility and functionality were tested by a four-point bending test. Finally, the theoretical values from the model were compared with the experimental results. This also includes a simple evaluation of whether this simplified modelling of the structure’s behaviour is appropriate. The paper contains a summary of the conditions that could have affected the results.
Validation of geotechnical laboratory tests data obtained from various sources
Authors: Pavelcová Veronika , Janda Tomáš
Published: December 2024

Data validation is a critical step in every data analysis. It is a well-known fact that the results of any data analysis are directly dependent on the input values. This paper works with a worldwide database of laboratory tests collected during four year operation of web calibration application ExCalibre and elaborates on the data correctness. ExCalibre application enables automatic calibration of three critical state models based on data from standard laboratory tests. The paper presents the rules and overall methodology for checking the validity of laboratory tests data and summarises the obtained results.
Transforming point cloud data into 3D BIM models: a case study on slabs
Authors: Zbirovský Slávek , Nežerka Václav
Published: December 2024

We explore the automatized transition of point cloud data into a Building Information Model (BIM), an essential task for reconstructions, demolition plans, or auditing. In this study, we use point cloud data generated by 3D laser scanning. The research elaborates on the process of segregating and segmenting floor slabs from point clouds and the developed algorithms categorize point cloud subsets based on different height parameters (z-coordinates). Once slabs are identified, a function is applied to create envelopes for each slab level, accommodating any convex or concave shape. The resulting geometry, along with relevant auxiliary data, is exported in the Industry Foundation Classes (IFC) format, a standard for BIM data exchange. The exported entities can then be further processed using prevalent software such as Revit or ArchiCAD.
Formulation and implementation of nonlinear elasticity in advanced constitutive models in geomechanics
Authors: Žalská Tereza , Šejnoha Michal , Janda Tomáš , Zemanová Alena
Published: December 2024

Several formulations of a nonlinear elastic behavior within the yield surface of the selected advanced constitutive models are described and compared. Since concentrating on geotechnical applications the accompanied numerical simulations are limited to basic laboratory tests such as isotropic compression, oedometer, and drained triaxial compression. The results show a significant influence of the size of the initial load step on final predictions particularly when starting from a very low initial stiffness associated with the assumed zero initial stress. Differences in the predicted response arising from different formulations are also discussed. These might be quite significant and the design engineer should be aware of that when choosing a particular computational software.
Modelling the leadership role of police in controlling COVID-19
Authors: Singh Vikram , Kapoor Shikha , Gupta Sandeep kumar , Sharma Sandeep
Published: December 2024

During the recent Coronavirus disease (COVID-19) pandemic, different parts of the globe faced indefinite lockdowns. To maintain the lockdown measures, government authorities deployed security forces and police. The primary role of the police is to monitor the movement of the people and advise/guide them to follow the lockdown. In the current work, we propose a nonlinear mathematical model to study the role of police and security personnel in controlling COVID-19. It is observed that the proposed model possesses two equilibria, namely, trivial and non-trivial. We performed the stability analysis of the non-trivial equilibrium point by using the compound matrix technique. Finally, we perform a detailed numerical simulation to investigate the feasibility of the theoretical results. The current study demonstrates that police forces played a significant role in controlling the pandemic.
The importance of the cerebro-placental ratio at term for predicting adverse perinatal outcomes in appropriate for gestational age fetuses
Authors: Josten Hannah , Heimann Yvonne , Lehmann Thomas , Schleußner Ekkehard , Groten Tanja , Weschenfelder Friederike
Published: December 2024

Objectives

This study investigates the relationship between the cerebro-placental ratio (CPR) measured at 40+0 weeks’ gestation and perinatal outcomes to determine a CPR cut-off that may justify induction of labor at term in appropriately grown fetuses (AGA). Although CPR is used for monitoring growth-restricted fetuses, its role in guiding labor induction decisions for AGA pregnancies at term remains unclear.

Methods

A retrospective cohort study was conducted using data from 491 singleton pregnancies with intended vaginal deliveries between 2015 and 2021. CPR was assessed at the actual estimated date of delivery (40+0 weeks’ gestation). Adverse Pregnancy Outcome (APO) as the primary endpoint was defined by admission to neonatal intensive care unit (NICU), umbilical cord blood pH<7.1, 5-min APGAR<7 or interventions-due-to-fetal-distress during labor (IDFD=vaginal-operative delivery or emergency caesarean section).

Results

APO nearly doubled (adjOR 1.7; CI 1.007–2.905) when CPR was below our calculated cut-off of 1.269 (18.4 vs. 32.3 %, p=0.002) and NICU admissions (4.8 vs. 11.1 %, p=0.020) and IDFD (12.5 vs. 21.2 %, p=0.027) significantly increased. The positive predictive value for the presence of APO using our cut-off was 32.4 %, and the negative predictive value 81.6 %.

Conclusions

Our data confirm a predictive value of a reduced CPR at term with impaired perinatal outcome. The cut-off of CPR<1.269 may guide decision-making regarding induction of labor. Further prospective studies are needed to confirm these findings.

Authors: Yi Shuai , Li Dan , Zhang Xin-lei , Duan Fen-yu , Gao Han , Kong Ming-jian
Published: December 2024

Objective

The aim of this study was to assess the impact of the external oblique intercostal block (EOIB) on early postoperative pain in patients who underwent laparoscopic cholecystectomy.

Methods

120 patients were divided into two groups: the EOIB group (Group E) and the control group (Group C). The assessed variables were mainly intraoperative remifentanil usage, numerical rating scale (NRS) pain scores at 0, 1, 2, 4, 6, 12, and 24 h postoperatively, cumulative fentanyl consumption within 24 h postoperatively and within the first-hour post-anesthesia care unit.

Results

Remifentanil consumption during surgery was significantly reduced in Group E compared to Group C. Postoperative fentanyl requirements were also lower in Group E at 1 and 24 h after surgery. Furthermore, Group E demonstrated significantly lower NRS scores at 0, 1, 2, 4, and 6 h postoperatively and a reduced need for rescue analgesia compared to Group C. However, at 12 h post-surgery, Group E’s NRS scores were slightly higher than Group C’s.

Conclusion

The EOIB is associated with reduced pain within the first 24 postoperative hours following laparoscopic cholecystectomy.

Young Generations’ Perception of Deadwood in Forest Landscapes
Authors: Bayraktar Selim , Becagli Claudia , Paletto Alessandro
Published: December 2024

Recently, citizens’ perceptions toward deadwood in forests have become increasingly important in recreational forests for socially sustainable management. The present study aims to investigate how deadwood in forests is perceived by the young generations (university and post-university students). This study was implemented by submitting a web-based questionnaire to 485 Turkish students. The results showed that our student sample perceived the key role in deadwood for soil fertilization, the provision of microhabitats, and food for wildlife. A high percentage of students positively viewed lying deadwood in forests, while standing dead trees were less positively perceived. The socio-demographic characteristics of respondents (gender and age) played a key role in explaining the variations in individual preferences toward deadwood. In conclusion, the results of this study highlight that despite students’ awareness of the ecological role of deadwood in forests, aesthetically they still prefer forests with moderate amount of deadwood or without deadwood. The findings obtained in this study can help decision-makers define a socially accepted forest management strategy.

Published: December 2024

Understanding the diameter structure of a stand is crucial for making informed decisions regarding silviculture and forest management. This is achieved by collecting forest inventory data and applying them to probability density functions. The objective of this study was to identify the optimal probability density function for describing the diameter distribution in a mixed temperate forest in Oaxaca, Mexico. Circular sampling plots of 1000 m² were established, and the diameter at breast height (DBH) and total height of 16,863 trees of the 25 most important timber species were measured. Four probability density functions (Weibull 2P, Log-Normal, Log-Logistic, and Burr) were fitted by using maximum likelihood approach for different silvicultural treatments. The predictive ability of the functions was evaluated using bias, root mean square error, Kolmogorov-Smirnov statistic and graphical analyses. In terms of accuracy and parsimony, the Burr function demonstrated the best performance, followed by the Log-Normal and Log-Logistic functions. Consequently, the Burr function is recommended for modeling the diameter distribution of stands under different treatments in the study site.

Published: December 2024

Picea omorika (Pančić) Purkyne is a well-known endemic conifer species. However, there have been few morpho-anatomical studies to date. Several years ago, preliminary population studies of P. omorika were published, but with the inclusion of additional populations, it became necessary to confirm whether the southernmost population from Mileševka Canyon, also known as var. vukomanii, (Pavlović and Matović 1994), remains distinct from the others. Two-year-old needles from the lower third of the crown were collected in late autumn from seven natural populations of P. omorika from Serbia and from the border with Bosnia and Herzegovina. The variability of ten morpho-anatomical traits and the cross-sectional anatomy of Serbian spruce needles were examined in seven natural populations in Serbia. Needle length was measured with a digital calliper, and the nine other needle traits, needle width, needle thickness, vascular bundle diameter, resin ducts diameter, number of resin ducts, distance between vascular bundle and resin duct, cuticle and epidermal thickness, hypodermal thickness, and hypodermal width, were examined under a light microscope. For most of the traits studied, the Štula population had the highest values, whereas the Bilo population had the lowest. Needles with triangular sections are most common in the southern part of Mt. Tara, while elliptical and rhomboidal sections are characteristic in populations at the edge of the distribution range in Serbia. Multivariate analyses separated populations into two main groups. Both principal component analysis and discriminant analysis indicated population overlap, while cluster analysis identified three main groups. Multivariate analysis of bioclimatic data and a correlation study of morpho-anatomical traits were also performed. Based on bioclimatic parameters, individuals in the populations from Mileševka and Štula showed the most distinct characteristics. Mantel and partial Mantel tests confirmed no correlation between the complete set of morphological traits and bioclimatic parameters, even after adjusting for regional differences.

Authors: De Carvalho Maria Naira , Borges da Silva Maria do Socorro
Published: December 2024

Este artigo analisa os resultados da pesquisa cartográfica realizada no Mestrado em Educação. O método é a cartografia e tem como território uma escola de Educação de Jovens e Adultos (EJA) da periferia da cidade de Teresina-PI. Objetiva mapear saberes, problemas e formas de resistência das mulheres negras da EJA, a partir de suas narrativas, usando a técnica de produção de dados “Bonecas que falam”. Com base teórica em Gonzalez (2020), Arroyo (2017) Collins e Bilge (2021) e Candau (2013), o estudo revelou que as participantes são portadoras de saberes e cotidianamente desenvolvem resistências, sendo a EJA um lugar de acolhimento, de sonhos e de fuga das suas opressões.

Authors: Boscardin Schühli Monica , Moro Catarina
Published: December 2024

Este artigo apresenta resultados parciais de uma pesquisa de mestrado, de abordagem qualitativa, que teve como propósito compreender como a pré-escola assegura ou não as especificidades da Educação Infantil em escolas da Rede Municipal de Ensino de Curitiba-PR, ao compartilhar a escola com o Ensino Fundamental. Explora-se as categorias crianças, direitos e infância(s) para discutir as especificidades da pré-escola presente nos documentos normativos e orientadores das escolas, nos planejamentos e registros de atividades propostas pelas professoras. Afirma-se o entendimento das crianças como sujeitos sociais e históricos, cidadãs e produtoras de cultura.
SOCIALIZAÇÃO ADULTOCÊNTRICA E CULTURAS INFANTIS
Authors: Sarmento Teresa
Published: December 2024

O artigo aborda o interesse crescente nos estudos sobre/para/com crianças, destacando a participação ativa das mesmas na sociedade, a começar pelos espaços educativos. É afirmada a concepção da criança como cidadã, que vive entre contextos, particularmente a família e a escola, destacando-se a importância de reconhecer sua agência e voz. A participação das crianças em relações interativas é crucial para a formação de cidadãos participativos, mas enfrenta obstáculos como a visão adultocêntrica e o desrespeito pelas culturas infantis. São também discutidas a influência das crianças na vida dos adultos e a necessidade de repensar modelos educativos. Conclui-se que é essencial reconhecer as crianças como agentes sociais e promover uma abordagem mais emancipatória da educação de infância.

PRODUTIVISMO E ENVELHECIMENTO NA CARREIRA DOCENTE
Authors: Oliveira Viana Lauro , Helal Diogo Henrique
Published: December 2024

O envelhecimento populacional é um fenômeno mundial, replicado no mercado de trabalho e nas universidades. O objetivo desta pesquisa foi identificar aspectos da regulamentação da carreira docente que induzem o produtivismo acadêmico. Foi feita análise de conteúdo da legislação federal e das regulamentações internas de uma universidade quanto a carreira docente do Magistério Superior Federal, desde o ingresso à pós-carreira. A pesquisa revelou há acúmulo de atribuições, em paralelo ao trabalho em sala de aula, e que a pós-graduação e a pesquisa possuem maior valorização diante das demais atividades acadêmicas.
Castoriadis, hoje
Authors: Do Valle Lílian
Published: December 2024

Qual a atualidade do pensamento e da obra de Castoriadis? Um primeiro elemento de resposta pode ser fornecido pela constatação da profundidade e originalidade de sua contribuição. Contudo, está claro que esta atualidade depende do que fazemos de seu pensamento, das razões pelas quais e das formas como o convocamos e, sobretudo, de como o fazemos frutificar. Por isso mesmo, a resposta a esta questão é necessariamente múltipla, tão variada quanto são as leituras que seus escritos suscitaram. Esse texto apresenta uma resposta bastante pessoal, que descreve uma trajetória inspirada pelo testemunho pessoal e pela influência teórica do autor.
O projeto de autonomia como criação ontológica em Castoriadis
Authors: Perrusi Martha Solange
Published: December 2024

Neste artigo, pretende-se elucidar a possibilidade do projeto de autonomia como criação e ruptura ontológica. Para tanto, discutimos o Ser como Caos, Abismo, Sem-Fundo e a significação do Ser em relação com as instituições da sociedade em suas formas heterônoma e autônoma.
DA FALTA DE SI À CONSCIÊNCIA DA PRÓPRIA DÉCADENCE EM NIETZSCHE
Authors: Toledo Ricardo de Oliveira
Published: December 2024

Aqui são investigados dois momentos do itinerário intelectual de Friedrich Wilhelm Nietzsche (1844-1900). O primeiro se refere a um trecho de Ecce Homo, composto em 1888, no qual ele discorre sobre uma enfermidade que o acometeu chamada por ele de “falta de si”. Esta decorreria, em especial, da sua devoção ao compositor Richard Wagner (1813-1883) e a tudo o que a este estava relacionado, especificamente, um hegelianismo implícito, o apreço por Arthur Schopenhauer (1788-1860) e o Romantismo alemão tardio. A libertação destes elementos compreende um pesado esforço de autossuperação observada no autor em obras como Humano, demasiado humano, Aurora e A Gaia Ciência. O segundo momento se volta para uma passagem de O caso Wagner, de 1888, na qual Nietzsche afirma ser ele próprio um décadent. Ora, se o filósofo alemão foi capaz de impor a si mesmo um rigoroso tratamento diante da “falta de si”, algo semelhante poderia ter sido empreendido no que diz respeito à sua décadence? Este problema implica outra pergunta: seria a décadence uma doença a ser curada? Para subsidiar as meditações sobre o assunto, são inseridos neste texto análises da décadence na filosofia nietzschiana, bem como algumas perspectivas interpretativas dessa temática. Ao cabo deste estudo, sugere-se uma avaliação hipotética das alternativas supostamente preconizadas por Nietzsche para a resistência diante da sua própria décadence.
EM DIREÇĀO A UMA CRÍTICA DO SUJEITO MODERNO: EXPLORANDO OS CONCEITOS DE INCONSCIENTE EM FREUD E O DE MEMÓRIA EM AGOSTINHO
Authors: Da Cunha Mariana Paolozzi Sérvulo , de Souza Nunes Marcus Vinicius
Published: December 2024

Embora a distância temporal entre Agostinho e Freud possa apresentar dificuldades no que se refere a aproximações conceituais, a tentativa deste artigo é reconhecer alguns conjuntos significantes que se estruturam em torno principalmente das noções de memória e de inconsciente. A finalidade de tal procedimento é identificar no que poderíamos chamar de uma antropologia, seja ela agostiniana ou freudiana, elementos para a crítica do sujeito da modernidade. Assim, serāo examinados o conceito de inconsciente freudiano e o de memória agostiniana e a sua referência a conteúdos latentes da mente, para em seguida ser pontuado o diferencial da memória agostiniana como sede de sabedoria e de transcendência, ideia ausente na teoria freudiana. Enquanto em Freud o sujeito fica desabrigado de si, não sendo senhor da própria casa, em Agostinho verifica-se a saída-de-si em direção a um ‘eu’ mais que ‘eu’. Ambos os autores se dedicam a investigar dimensões ocultas e desconhecidas da subjetividade, buscando lhes atribuir alguma inteligibilidade. Com isso explicitam-se elementos para uma crítica dessa “invenção “da modernidade, isto é, o sujeito tido como autossuficiente e autocentrado.
Niilismo metafísico e incompossibilidade em Leibniz
Authors: Santovich Scaramal Elliot
Published: December 2024

O objetivo do presente artigo é analisar a sugestão feita por Leibniz em um apêndice à única obra de grande porte publicada pelo autor, i.e. os Ensaios de Teodiceia, de que é possível que nenhum mundo tivesse existido ou que Deus poderia não simplesmente não ter criado esse mundo, mas poderia mesmo não ter criado mundo algum, uma posição que, como pretendemos argumentar, pode ser caracterizada como um tipo de niilismo metafísico avant la lettre. Nas seções 1, 2 e 3, pretendemos precisar em que sentido estamos atribuindo uma forma de niilismo metafísico a Leibniz, assim como apresentaremos argumentos exegéticos e sistemáticos para sustentar essa atribuição. Na seção 4, consideraremos a consistência dessa sugestão por parte de Leibniz com o restante da sua metafísica, defendendo que é possível interpretar a última de uma maneira que seja consistente com a primeira. Finalmente, na seção 5, discutiremos as consequências de uma tal interpretação da metafísica leibniziana para a questão clássica da incompossibilidade entre substâncias possíveis, sugerindo então que, uma vez estabelecida a tese do niilismo metafísico no contexto da metafísica de Leibniz, não seria a prevenção estritamente de uma forma de necessitarismo que estaria em jogo na solução do problema, mas sim o estabelecimento de uma pluralidade de mundos possíveis alternativos.
A EPISTEMOLOGIA DA JUSTIÇA [ELIZABETH ANDERSON]
Authors: Fanton Marcos , Rosa Juliano Pires da
Published: December 2024

Em discussões sobre justiça, diferentes perspectivas geralmente compartilham princípios morais, mas chegam a conclusões distintas sobre justiça, porque discordam sobre fatos. Argumento que o raciocínio motivado, a injustiça epistêmica e as ideologias de injustiça apoiam instituições injustas ao consolidarem representações distorcidas do mundo. Partindo de uma concepção naturalista de justiça como um tipo de contrato social, sugerirei algumas estratégias para descobrir o que a justiça demanda, neutralizando esses vieses. Sentimentos morais oferecem recursos essenciais para esse fim.
O universalismo de Sueli Carneiro
Authors: Frateschi Yara
Published: December 2024

Este artigo pretende refletir a respeito do universalismo de Sueli Carneiro, que, na minha interpretação, se estabelece por oposição ao universalismo excludente e “substitucionalista” que encontramos em diversas filosofias ocidentais. Carneiro é universalista na medida em que almeja a efetivação da liberdade e da igualdade para todos e na medida em que se revela defensora inconteste dos direitos humanos. Mas há ainda outra dimensão do universalismo carneriano, desenvolvida em Dispositivo de racialidade: a construção do outro como não ser como fundamento do ser, e que se baseia na distinção heidegeriana entre o ôntico e o ontológico para defender que a redução ao particular aprisiona o indivíduo, ao passo que “é a ideia de universalidade que emancipa o indivíduo e permite-lhe expressar a sua especificidade”. A tese segundo a qual o universal é emancipador é valiosa num momento, como o nosso, em que as teorias universalistas estão sob o escrutínio da crítica por diversos ângulos e perspectivas. Carneiro inverte o sentido da oposição entre o particular e o universal, comumente presente nas críticas anti-universalistas ao universalismo excludente, ao tornar excludente o particular e emancipador o universal.
