Published: June 2023

O Brasil é o maior produtor de cana-de-açúcar do mundo e seus subprodutos, sendo que na safra de 2020/21 a moagem de cana-de-açúcar no Brasil foi de 657.433 mil toneladas, sendo a região Norte-nordeste responsável por 7,9% e a região Centro-sul por 92,1%, na qual apenas o estado de São Paulo é responsável por 54,22% da moagem brasileira (UNICA, 2022). Desde o surgimento da cultura no Brasil até 2002 se predominava o sistema manual na colheita, até a chegada da Lei n. 11.241 de 2002 e do Protocolo Agroambiental de 2007 que impulsionaram a mecanização na colheita, devido a proibição da prática da queima da palhada, o que resultou em mudanças no setor sucroenergético. Esse trabalho teve como objetivo analisar as mudanças ocasionadas no setor sucroenergético ocorridas pela transição do sistema de colheita manual para colheita mecanizada, ressaltando os aspectos econômicos, sociais e ambientais, ao longo das safras de 2000/01 a 2018/19, para o setor no Estado de São Paulo, tendo como metodologia a utilização de dados secundários que serão obtidos por meio de revisões bibliográficas, livros, trabalhos acadêmicos, entre outras produções existentes na literatura relacionados à área com ênfase no processo de colheita da cana-de-açúcar. Como resultado obteve-se no aspecto econômico que, da safra de 2007/08 para a safra 2018/19, ocorreu um aumento de 4437 colhedoras no estado de São Paulo e a área colhida mecanicamente saltou de 33% para 93,3%, enquanto a manual regrediu de 67% para 6,7%. No aspecto social pode- se notar uma redução de 222.943 vagas de atividades manuais no setor, desde 2007/08 a 2018/19, e um aumento no valor pago aos cortadores de cana. Já no âmbito ambiental nota-se uma redução de 46% no consumo de água, da safra 2010/11 para safra 2018/19, para produção de 1 tonelada de cana e, da safra de 2006/07 a 2020/21teve-se uma redução de 1,63 milhões de hectares com o uso da queimada autorizada e uma redução de 11,82 milhões de CO2 emitidos na at9fera. Nesse sentido, conclui-se que com a chegada do Protocolo Ambiental, em 2007, a prática da queimada da palhada teve seu uso limitado e gerou avanços no sistema de colheita, esses que resultaram em uma colheita mais sustentável e com menor número de mão de obra uma vez que as colhedoras tinham maior capacidade de colheita.

Published: June 2023

En el contexto chileno, actualmente, conviven diferentes culturas debido al fenómeno migratorio mundial, lo que ha obligado a replantearse el quehacer educativo. El presente artículo pretende recoger información relevante acerca de las prácticas pedagógicas de un grupo de educadoras de párvulos que han trabajado con familias migrantes en sus jardines infantiles. Mediante la metodología cualitativa, con la aplicación de entrevistas semiestructuradas y un grupo focal, se recopilaron las percepciones de las profesionales de la educación sobre las características culturales de crianza de las familias migrantes y su impacto en las prácticas pedagógicas. El principal hallazgo fue que las educadoras de párvulos no valoran los saberes, conocimientos y contextos de las familias migrantes como factores contribuyentes al proceso de aprendizaje. Se concluye que, para lograr caminar hacia una educación inicial intercultural, se debe considerar la crianza intercultural como un recurso que aporta al proceso de aprendizaje integral de los niños y niñas.

Published: June 2023

The environmental potential which is quite large economically has been misused to obtain the maximum profit. This can be seen from the many cases of law violations in the environmental sector and physical evidence of environmental damage due to wrongful exploitation. Certain interests that come into play in environmental management have damaged the environmental law management system itself. Law is only used as a tool to control natural resources legally. Many state officials cooperate with unscrupulous businessmen to exploit the environment freely without paying attention to the boundaries that are the size that should be the reference. In Indonesia environmental problems are important and urgent to be addressed by finding solutions to solve them. Therefore environmental management laws must always be accompanied by civilized Indonesian human attitudes, namely an attitude that shows the quality of Indonesian humanity which is based on religion, culture and science. So that on this basis the environment can be managed properly, not only for business benefits, but also for the welfare of society and for the benefit of the universe.

Published: June 2023

The daily use of websites aims to facilitate humans in their activities. The creation of a website must pay attention to factors related to user usability. Usability on a website must be considered because so that users who use the website feel comfortable in using the website and easily obtain the desired information. One of the websites supporting lecture activities is SIKULI UMRI. SIKULI is a lecture support system in the form of an e-learning website, but there are still several errors that cause discomfort to its users. Services or features available on SIKULI include home pages, course schedules, course pages, authorization details, course outcomes and descriptions, meetings, and grade data. This research aims to see and analyze usability based on ISO 9241-11. The three aspects of Usability measurement according to IS0 9241-11, namely Effectiveness, Efficiency, and Satisfaction are latent variables so that they cannot be calculated directly so that they require analysis that can connect these variables. Data collection was carried out by distributing research questionnaires to SIKULI website users and continued by testing the validity and reliability of the data. The results of this study indicate that SIKULI has been said to be quite good with the value of the Usability variable R-Square relationship of 66.8%.
Stellar Rotation and Structure of the α Persei Complex: When Does Gyrochronology Start to Work?
Authors: Boyle Andrew W. , Bouma Luke G.
Published: June 2023

On the pre-main sequence, the rotation rates of Sun-like stars are dictated by the interplay between the protostellar disk and the star’s contraction. At ages exceeding 100 Myr, magnetic spindown erases the initial stellar spin rate and enables rotation-based age dating (gyrochronology). The exact time at which the transition between these two regimes occurs depends on stellar mass, and has been challenging to empirically resolve due to a lack of viable calibration clusters. The α Persei open cluster (t ≈ 80 Myr, d ≈ 170 pc) may provide the needed calibrator, but recent analyses of the Gaia data have provided wildly varying views of its age and spatial extent. As such, we analyze a combination of TESS, Gaia, and LAMOST data to calibrate gyrochronology at the age of α Per and to uncover the cluster’s true morphology. By assembling a list of rotationally confirmed α Per members, we provide strong evidence that α Per is part of a larger complex of similarly aged stars. Through kinematic back-integration, we show that the most diffuse components of α Per were five times closer together 50 Myr ago. Finally, we use our stellar rotation periods to derive a relative gyrochronology age for α Per of 67% ± 12% the age of the Pleiades, which yields 86 ± 16 Myr given current knowledge. We show that by this age, stars more massive than ≈0.8 M
⊙ have converged to form a well-defined slow sequence.

Published: June 2023

Type I X-ray bursts are rapidly brightening phenomena triggered by thermonuclear burning on the accreting layers of a neutron star (NS). The light curves represent the physical properties of NSs and the nuclear reactions on the proton-rich nuclei. The numerical treatments of the accreting NS and physics of the NS interior are not established, which shows uncertainty in modeling for observed X-ray light curves. In this study, we investigate theoretical X-ray burst models compared with burst light curves with GS 1826-24 observations. We focus on the impacts of the NS mass and radius and base heating on the NS surface using the MESA code. We find a monotonic correlation between the NS mass and the parameters of the light curve. The higher the mass, the longer the recurrence time and the greater the peak luminosity. While the larger the radius, the longer the recurrence time, the peak luminosity remains nearly constant. In the case of increasing base heating, both the recurrence time and peak luminosity decrease. We also examine the above results with a different numerical code, HERES, based on general relativity and consider the central NS. We find that the burst rate, energy, and strength are almost the same in two X-ray burst codes by adjusting the base heat parameter in MESA (the relative errors ≲5%), while the duration and rise times are significantly different between (the relative error is possibly ∼50%). The peak luminosity and the e-folding time change irregularly between two codes for different accretion rates.
Steep Balmer Decrement in Weak AGNs May Not Be Caused by Dust Extinction: Clues from Low-luminosity AGNs and Changing-look AGNs
Authors: Wu Jiancheng , Wu Qingwen , Xue Hanrui , Lei Weihua , Lyu Bing
Published: June 2023

The hydrogen Balmer decrement (e.g., Hα/Hβ) is widely adopted as an indicator of the internal reddening of active galactic nuclei (AGNs). This is challenged by some low-luminosity AGNs and changing-look AGNs (CLAGNs), which have steep Balmer decrement but without strong evidence for absorption. We compile a sample of normal AGNs and CLAGNs with a wider distribution of bolometric Eddington ratio (λ
Edd = L
bol/L
Edd) and find a strong negative correlation between Hα/Hβ and λ
Edd, which suggests that the Balmer decrement is also accretion-rate dependent. We further explore the Balmer decrement based on the photoionization model using the Cloudy code by considering spectral energy distribution from the accretion disk with different accretion rates (e.g., disk/corona and truncated disk at high and low Eddington ratios, respectively). Both the standard disk and truncated disk predict a negative correlation of Hα/Hβ–λ
Edd, where the relation is steeper in the case of the truncated disk. The negative correlations are also explored in two single CLAGNs. The measured negative correlation of Hα/Hβ–λ
Edd is mainly caused by the lower responsivity

in Hα relative to that in Hβ due to the larger optical depth in the former. We propose that the steep Balmer decrements in low Eddington ratio AGNs (e.g., some Seyferts 1.5–1.9 and CLAGNs) are not simply caused by absorption but mainly caused by the relatively low flux of ionizing photons.
Sparse Logistic Regression for RR Lyrae versus Binaries Classification
Authors: Trevisan Piero , Pasquato Mario , Carenini Gaia , Mekhaël Nicolas , Braga Vittorio F. , Bono Giuseppe , Abbas Mohamad
Published: June 2023

RR Lyrae (RRL) stars are old, low-mass, radially pulsating variable stars in their core helium burning phase. They are popular stellar tracers and primary distance indicators since they obey well-defined period–luminosity relations in the near-infrared regime. Their photometric identification is not trivial; indeed, RRL star samples can be contaminated by eclipsing binaries, especially in large data sets produced by fully automatic pipelines. Interpretable machine-learning approaches for separating eclipsing binaries from RRL stars are thus needed. Ideally, they should be able to achieve high precision in identifying RRL stars while generalizing new data from different instruments. In this paper, we train a simple logistic regression classifier on Catalina Sky Survey (CSS) light curves. It achieves a precision of 87% at 78% recall for the RRL star class on unseen CSS light curves. It generalizes on out-of-sample data (ASAS/ASAS-SN light curves) with a precision of 85% at 96% recall. We also considered a L1-regularized version of our classifier, which reaches 90% sparsity in the light-curve features with a limited trade-off in accuracy on our CSS validation set and—remarkably—also on the ASAS/ASAS-SN light-curve test set. Logistic regression is natively interpretable, and regularization allows us to point out the parts of the light curves that matter the most in classification. We thus achieved both good generalization and full interpretability.
Solar Filament Eruptions in H

Published: June 2023

We use observations taken with a novel solar telescope spectroheliograph to investigate the association between the early filament rise and coronal mass ejections (CMEs). The instrument allows the H
α
full line profile to be registered in each pixel of the solar disk with a time cadence of about 1 minute. We analyze observations of three eruptive filaments in 2021 and show that patrol telescope measurements of the H
α
line profile with a spectral resolution R = 40,000 can be used to detect precursors of filament eruptions with an advance of several hours and to estimate the initial acceleration of CMEs. Our limited case study also suggests that while detecting an early filament rise may serve as an indicator of a possible eruption, the filament ascent alone is not a definite sign of a CME.
Radiation Pressure Acting on the Neutral He Atoms in the Heliosphere
Authors: Kowalska-Leszczynska I. , Kubiak M. A. , Bzowski M.
Published: June 2023

Interstellar neutral helium (ISN He) is an important source of information on the physical state of the local interstellar medium. Radiation pressure acting on the neutral helium atoms in the heliosphere has always been neglected; its effect has been considered insignificant compared to gravitational force. The most advanced numerical models of ISN He take into account more and more subtle effects; therefore, it is important to check if the effect of radiation pressure is still negligible. In this paper, we use the most up-to-date version of the Warsaw Test Particle Model (WTPM) to calculate the expected helium distribution in the heliosphere and simulate the flux of the ISN He observed by the Interstellar Boundary Explorer (IBEX) and in the future by the Interstellar Mapping and Acceleration Probe (IMAP). We compare results calculated with and without radiation pressure during low and high solar activity. The results show that in the analysis of IBEX-Lo observations, the radiation pressure acting on typical helium causes flux differences at a level of 1%–4% and is comparable to the observational errors. For the more sensitive IMAP-Lo instrument, there are some regions in the considered observation configurations where radiation pressure causes potentially statistically significant changes in the calculated fluxes. The effect can be up to 9% for the indirect beam and is likely to be higher than the estimated errors. Therefore, we claim that in the future analysis of the IMAP-Lo observations, radiation pressure acting on ISN He should be considered.

The global pandemic of the novel coronavirus (COVID-19) declared in March 2020 has created unprecedented challenges for healthcare professionals and organizations. A significant impact has been physical and psychological stress on nurses working in acute care environments. Stress-related growth may occur concurrently with the experience of negative psychological responses as another facet of coping and adjustment to the stressful event. The primary aim of this study was to describe the degree to which nurses reported stress, anxiety, and stress-related growth during the COVID-19 pandemic. This article discusses the study methods, which included a cross-sectional design with an online survey sent to nurses in a hospital system. Results demonstrated that, of the 1,009 participants in the final analysis, almost 70% reported anxiety symptoms, with 38% having scores at the moderate or severe level. Growth scores were low. Our discussion considers cultural implications of the findings and implications for practice that underscore the need for proactive interventions to mitigate the psychological burden of the pandemic on nurses and the need to implement routine screening of nurses for anxiety.
Accessibility and Financial Barriers in the Utilization of Alternative to Discipline Programs in the United States

Nurses are facing increased mental health issues, substance use, and even suicide since the novel coronavirus pandemic arrived in the United States. Nurses with substance use disorder (SUD) may enroll in alternative-to-discipline (ATD) programs to retain their license during initial treatment with the goal to return to practice, but this process is not without challenges. For example, previous analyses have shown that the time surrounding disciplinary/regulatory process regarding substance use disorder (SUD) by either employers or licensure boards was a trigger for nurses who died by suicide. Internet searches are a common approach to find information on health-related topics. This limited critical review sought to replicate and evaluate a simple internet search that a nurse seeking information on their state ATD program may complete. Google searches for information on ATD programs were completed on the 50 continental states and Washington, DC between April and September 2022. States with ATD programs were evaluated for evidence-based components and barriers to accessing program information. Publicly available ATD program information ranged from requirements for contact information to obtain details to websites that outline the entire program, including associated costs. While ATD programs offer a significant improvement over traditional disciplinary responses to nurse substance use, a significant barrier is program cost, which can often exclude participation. In this article, we discuss the detailed results of our critical review and offer implications for practice that include opportunities for research and a national database to track ATD program components and target outcomes to support return to practice for nurses with SUDs.
Largesses, pots-de-vin et « diplomatie du vin » ? Les dons en vin sous le principat de Jean sans Peur (1404-1419)
Authors: Rameau Baptiste
Published: June 2023

Bien de consommation mais également de prestige, le vin, notamment celui de Bourgogne, apparaît dès le principat de Philippe le Hardi comme un outil politique ; caractéristique qui se perpétue sous ses successeurs et notamment sous son petit-fils, Philippe le Bon, considéré comme « le prince des meilleurs vins de la Chrétienté ». Les dons en vin sous les ducs Valois de Bourgogne constituent donc un observatoire privilégié pour analyser la communication politique et symbolique, ainsi que les réseaux gravitant autour du prince. Centré sur Jean sans Peur (1404-1419), cet article entend, après une présentation des gratifications en lien avec les nombreux événements ponctuant le principat du deuxième duc de la maison Valois de Bourgogne, étudier cet aspect de l’économie du don en mettant l’accent sur les caractéristiques des vins et les bénéficiaires les plus récurrents dans les comptabilités bourguignonnes.
4. L’année 1797 – économie et romantisme
Authors: Vogl Joseph
Published: June 2023

En partant de réflexions méthodologiques sur l’histoire de l’économie politique depuis le xvii e  siècle, cet article cible une date marquante de l’économie financière. Alors qu’en février 1797, le projet des assignats français doit être reconnu comme un échec, au même moment, le Bank Restriction Act anglais, qui interdit la convertibilité des billets de banque en métal précieux, est perçu comme un tournant historique et un défi pour l’analyse économique. Les romantiques allemands, en particulier, voient dans l’expérience anglaise un projet à l’avenir prometteur – à la différence de la monnaie révolutionnaire française –, dans lequel le crédit public en circulation et les nouvelles théories du crédit deviennent des modèles pour une modernisation des concepts de systèmes économiques, politiques et sociaux.

La catachrèse pour regarder autrement le travail et les modalités de son apprentissage
Authors: Balas Stéphane
Published: June 2023

C’est sur la volonté de subordonner la conception de dispositifs de formation à une analyse préalable du travail que s’est peu à peu construite, notamment au CNAM, la didactique professionnelle. Définie comme l’analyse du travail en vue du développement de compétences, la didactique professionnelle se caractérise par l’adoption d’un regard sur l’apprentissage établi du point de vue de l’activité (en l’occurrence de l’activité professionnelle) mais aussi sur l’apprentissage établi du point de vue du développement du sujet (plus exactement du développement de ses compétences). Il s’agit donc, pour former un formateur à l’analyse du travail, de l’aider à « changer de regard », à l’éduquer.
Formateur/maître d’apprentissage : une rivalité féconde ?
Authors: Léonard Érika
Published: June 2023

Formateur et maître d’apprentissage sont les deux principaux référents de l’apprenti. Tous deux occupent pourtant un territoire singulier et circonscrit. Au premier incombe la formation en vue de l’obtention du diplôme, dans l’espace clos du centre de formation. Au second revient la confrontation à l’activité professionnelle réelle, hors les murs, comme dans la vraie vie. Tous deux ont pourtant une mission commune : assurer la montée en compétences de « leur » apprenti, même s’ils le confrontent à des pratiques et des discours parfois contradictoires. Sur fond de rivalité réelle ou fantasmée, ils offrent néanmoins à l’apprenti la possibilité de se positionner et de tracer sa voie. L’article montre la fécondité de cette rivalité.
Présupposés et logiques scientifiques de l’analyse du travail en sciences de l’éducation et de la formation
Authors: Thievenaz Joris
Published: June 2023

En partant du constat de l’intérêt de la recherche en sciences de l’éducation et de la formation pour les concepts et les méthodes de l’analyse du travail, cet article propose de réinterroger plusieurs présupposés et logiques scientifiques qui sous-tendent ce type d’approches. Il s’agit de questionner les fondements de ces travaux, les facteurs sociaux, culturels et académiques qui concourent à leur développement, ainsi que les tensions qui les traversent. L’article s’inscrit dans une réflexion épistémologique plus générale, consistant à remettre à l’étude les catégories d’analyse élaborées durant les dernières décennies dans la recherche en éducation et formation.

La médiation, une mise en relation
Authors: Betton Emmanuelle
Published: June 2023

S’appuyant sur une comparaison entre la pratique pédagogique et une pratique thérapeutique à médiation artistique, l’article interroge le travail de médiation qui s’exerce au cœur de la relation pédagogique, dans un contexte de développement des moyens de diffusion des savoirs et de digitalisation de la formation. Un tel contexte constitue une opportunité d’accès aux savoirs mais aussi le risque de confondre mise à disposition de savoirs et expérience de formation, et de minorer l’activité de médiation inhérente à la pratique de formation. En tant que mode de présence, modalités de relation et effets de résonance, les phénomènes d’attention conjointe sont proposés comme axes de réflexion pour la compréhension de ce qui peut se jouer dans la relation pédagogique lorsqu’elle se déploie dans l’immédiateté de la coprésence. Le parallèle avec les pratiques thérapeutiques à médiation musicale permet d’introduire la dimension de soin dans l’acte éducatif ou formatif.
Les investissements immatériels en contexte de transition : quelle économie de la formation ?
Authors: De Gasparo Sandro , Demissy Romain
Published: June 2023

La notion d’« investissement immatériel », développée par Pierre Caspar, s’avère particulièrement utile pour penser une économie de la formation à la hauteur des enjeux contemporains de la transition écologique et sociétale. À condition néanmoins de la revisiter à partir des enjeux du travail vivant, d’une conception renouvelée du modèle de développement économique et des dynamiques collectives à l’échelle des territoires de vie. Après une présentation de l’actualité du travail de Pierre Caspar, sont présentés et discutés deux témoignages d’organisations engagées depuis de nombreuses années dans des dispositifs d’appui au développement de compétences au service de la transition. La conclusion propose une perspective s’appuyant sur l’expérience du travail pour penser une économie de la formation en contexte de transition.
Les pratiques d’accompagnement des flexpatriés
Authors: Lichere Simon , Melin Christopher
Published: June 2023

Les organisations ont de plus en plus recours à la flexpatriation pour le développement de leurs activités dispersées géographiquement. La littérature s’est principalement penchée sur les gains et coûts de ces affectations pour les organisations mais très peu sur l’impact de celles-ci sur les employés. Dans cet article, nous étudions les enjeux d’accompagnement en mobilité des flexpatriés dans un contexte particulier de crise sanitaire. À partir d’une étude exploratoire de 17 entretiens semi-directifs, complétée par 7 retours post-Covid, nous illustrons les situations particulières de travail des flexpatriés, leurs pratiques d’accompagnement, nous questionnons aussi les évolutions de la flexpatriation et les impacts de la crise sur celle-ci.
Advanced platelet rich fibrin in periodontal regeneration
Authors: Rathod Aishwarya , Jaiswal Priyanka , Masurkar Deepika
Published: June 2023

Regenerating periodontal tissue is the main goal of periodontal therapy. Periodontal tissue regeneration involves the development of new bone, cement, and periodontal ligaments on damaged tooth root surfaces in order to restore anatomy and function. In order to further enhance PRF (Platelet rich fibrin) and develop advanced platelet-rich fibrin, a slower rotating speed is proposed (A-PRFs). Cell dispersion is affected by centrifugation rate. The majority of the leukocytes in the PRF are concentrated near the bottom of the tube due to centrifugation rate. By switching the centrifugation process to 1,500 rpm for 14 minutes, granulocyte neutrophils and the fibrin matrix are more evenly distributed in the A-PRF created. Hence, a periodontal evaluation of this subject is required.

Published: June 2023

Plantar pressure can signify the gait performance of patients with Parkinson's disease (PD). This study proposed a plantar pressure analysis method with the dynamics feature of the sub-regions plantar pressure signals. Specifically, each side's plantar pressure signals were divided into five sub-regions. Moreover, a dynamics feature extractor (DFE) was designed to extract features of the sub-regions signals. The radial basis function neural network (RBFNN) was used to learn and store gait dynamics. And a classification mechanism based on the output error in RBFNN was proposed. The classification accuracy of the proposed method achieved 100.00% in PD diagnosis and 95.89% in severity assessment on the online dataset, and 96.00% in severity assessment on our dataset. The experimental results suggested that the proposed method had the capability to signify the gait dynamics of PD patients.
