Authors: Wang Qing , Xu Ziyi , Tao Jingjing , Brown Scott
Published: November 2023

Educational coaching can positively influence student learning in various ways. This study focuses on specific teachers’ classroom-coaching behaviours (TCCBs) and explores their influence on student learning from a cross-cultural perspective. The study was conducted based on two samples of undergraduate students from China (N = 288) and the United States of America (N = 325). The results show that although TCCBs positively influenced students’ learning variables in both samples, significant cultural differences in TCCB existed as perceived by Chinese and American students. Furthermore, TCCBs had stronger positive impacts on the American students’ deep learning and academic buoyancy than on the Chinese students. The study attempts to explain cross-cultural differences in the impact of classroom coaching on student learning and offers practical recommendations for classroom coaching.

Authors: Pimentel Patrícia Guedes , Teixeira Wenceslau Geraldes
Published: November 2023

O conhecimento do uso da terra é cada vez mais importante, principalmente para a manutenção das atividades de conservação das características naturais em ambientes urbanizados. O Jardim Botânico do Rio de Janeiro (JBRJ) está situado no município do Rio de Janeiro, tendo uma parte de sua área com cobertura de formação vegetal natural e parte antropizada (canteiros, jardins, gramados, caminhos, obras civis, etc). No que se refere aos fluxos de água superficiais, recebe as contribuições do Rio dos Macacos e seus afluentes, de nascentes localizadas na encosta do Maciço da Tijuca e entorno. O presente estudo teve como objetivo avaliar a evolução do uso e cobertura da terra na Microbacia do Rio dos Macacos, através de mapeamentos em diferentes anos de observação (2009, 2013 e 2017). Foi utilizada a combinação de imagens de satélite Landsat e dados altimétricos do Shuttle Radar Topography Mission no software livre Quantum GIS (QGIS, versão Desktop 3.10.5) para criar um Modelo Digital de Elevação (MDE). A partir da delimitação da microbacia conforme suas características de drenagem, foram elaborados os mapas de uso e cobertura da terra com dados vetoriais correspondentes a cada ano analisado, e o mapa de declividade e hipsometria, através das curvas de nível com espaçamento vertical de 10 metros. Apesar de pouco expressiva em comparação à área total da microbacia, verificou-se uma perda de 1 ha de cobertura arbórea e arbustiva no período analisado, causada em função de deslizamentos e movimentos de massa.

Immigration Law Exceptionalism and the Administrative Procedure Act
Authors: Family Jill E.
Published: November 2023

Immigration law is exceptional enough to deserve an administrative law focus of its own. The Administrative Procedure Act (APA) does not demand uniformity in adjudication. Therefore, it may be counterintuitive to argue that any one area of administrative adjudication is exceptional. Removal adjudication is indeed exceptional because it is an extremely dysfunctional system, it operates in a double void of fewer constitutional protections and without the protections of the APA, it relies on a vast network of civil detention, and it is of a different genre than the type of regulation that drove the development of the APA. The exceptionality of removal adjudication demands a review of administrative law doctrine with this exceptionality in mind.

Published: November 2023

The new school year 2023/2024 is a new episode for SMP Negeri 3 Lembang because, in the odd semester of 2023, the independent learning curriculum began to be implemented, the implementation of which began in grade 7. One part of the independent learning curriculum is the existence of assessments, where in its division the assessment is divided into cognitive and non-cognitive diagnostic assessments. The assessment is applied in all subjects including PAI subjects. Starting from the implementation of the independent learning curriculum at SMPN 3 Lembang this year, researchers conducted a cognitive diagnostic assessment in PAI subjects in the first chapter, namely Al-Quran and Hadith as a guide to life with five quiz questions given to 302 students in grades 7D to 7K to find out the extent of students' understanding of the material to be learned. This research uses a qualitative approach with a field study method, while data analysis is carried out quantitatively descriptively. The results concluded that the cognitive diagnostic assessment of students was categorized as low at 72% (combined grades C and D) as many as 214 students did not pass, and the remaining 5% (15 students) were categorized as very good (A), and 23% (70 students) were categorized as good (B). This can occur due to the factor of students' unfocused ness in participating in PAI learning, the surrounding environment that also influences, and the support and attention of parents also contribute.

Authors: Naffati Abdulhakim B. , Agena Mahmoud B.
Published: November 2023

Background: Fluoride is characterized by high toxicity, especially in prolonged exposures. Some plants including Rosemary can higher of accumulate up to 20 000 times this element concentration  in the environment. Consumption of highly fluoridated rosemary can contribute fluorosis and other body dysfunctions. Aims: This study aims to evaluate and optimize the extraction procedure of fluorides from the dried leaves of the plant, and compare the fluoride levels in collected samples. Methodology: nine of Rosemary samples from different countries including Libya, southern Serbia, Vojvodina and Istria were investigated in this study. Fluoride levels was determined potentiometrically using the calibration curve, via fluoride-selective electrode method based on lanthanum fluoride monocrystal. The sensitivity of the method was defined on the basis of 3SD criteria 3 using excel software. Results: fluoride concentration in investigated samples was varied. Libyan samples contained (1.8ppm) which is higher than other samples that ranged between 0.07 to0.49 ppm. However, all samples found to have fluoride concentration ranged with the recommended levels and less than the toxic or lethal doses. Conclusion: The modified potentiometric method using fluoride-selective electrode techniques for fluoride determination is highly effective with detection limit of 10 -9 mg/100g and is recommended in quantification of fluoride in Rosemary and other plant or spice samples. However, Results obtained by this study indicated that all samples contained different levels of in which all do not exceed the daily intake. Recommendations. Rosemary may offer an essential levels of required fluoride for daily intake. Further studies are recommended especially in areas with high fluoride content either in soil or via air pollution especially where rosemary is highly consumed to avoid fluorosis.

[...] Vous avez été celui qui sait et celui qui admire". Connu pour la découverte de la faune quaternaire de Saint Druon (quartier de Cambrai), Joseph Godon, chanoine et professeur de sciences, étudia d'autres disciplines que la géologie. A la lumière de récentes recherches, le présent article a pour but de présenter la vie et l'œuvre de ce véritable naturaliste régional.
Vingt siècles d’exploitation des argiles plastiques d’Andenne (Belgique) : du gisement au musée de la céramique
Authors: Goemaere Eric , Declercq Pierre-Yves , Quinif Yves
Published: November 2023

Disposés en chapelets, les gisements de terres plastiques d’Andenne occupent des remplissages de cryptokarsts à argiles blanches ou colorées et associés à 3 bandes de calcaires dinantiens ou frasniens orientées E-W. Sables, lignites et argiles tertiaires (Néogène) se sont accumulés au fur et à mesure de la dissolution karstique formant une poche pouvant atteindre 100m de profondeur. L’acide sulfurique issu de l’oxydation des sulfures des lignites est le principal responsable de la formation d’argiles kaoliniques aux dépens des minéraux argileux et des feldspaths présents dans les sables. Les circulations d’eau ont induit le lessivage du fer et son accumulation dans certains horizons. Les argiles blanches riches en alumine et pauvres en fer et en alcalins ont été les plus recherchées pour leurs propriétés réfractaires. Exploités d’abord en surface puis en galeries souterraines, l’extraction a atteint son développement maximal au tournant des XIXe et XXe siècles pour définitivement s’arrêter vers 1970. L’argile et le sable blanc lessivé furent employées dans les industries du feu : verrerie, cristallerie, métallurgie... et alimentèrent les poteries, briqueteries, tuileries, faïenceries, porcelaineries, piperies et la fabrication des réfractaires industriels. L’argile blanche d’abord puis les produits finis ont été exportés dès le Moyen Age en Hollande, en Allemagne et en France, contribuant à la renommée internationale des argiles andennaises. Les dépressions engendrées par la subsidence qui a suivi les extractions souterraines forment un chapelet de mares et d’étangs, sources de biodiversité. Enfin, le Musée de la Céramique conserve les traces de ce remarquable patrimoine géologique, minier, industriel et artistique en présentant ses collections exceptionnelles de faïences, porcelaines et pipes. Musée vivant porteur de mémoire, il assure des fonctions éducatives et culturelles par ses expositions temporaires.
Rôle des conservatoires d'espaces naturels dans la protection du patrimoine géologique – Exemple de la réserve naturelle régionale des anciennes carrières de Cléty (Pas-de-Calais)
Authors: Guyétant Gaëlle
Published: November 2023

Le Conservatoire d'espaces naturels du Nord et du Pas-de-Calais (CEN) agit depuis 1997 en faveur du patrimoine géologique. Ses actions se déclinent à deux échelles, régionale (inventaires, stratégies de protection et de valorisation) et locale (protection et gestion de sites géologiques remarquables). Les anciennes carrières de Cléty illustrent parfaitement cette double démarche. Reconnues dans un premier inventaire régional du patrimoine géologique en 1997, leur protection a été initiée par la commune de Cléty (propriétaire) et le CEN dès 1999. Aujourd'hui, la gestion et les aménagements mis en place font de ce site un espace reconnu en Nord - Pas-de-Calais pour la sensibilisation aux sciences de la Terre et la protection du patrimoine géologique.

Peak all et sobriété énergétique
Authors: Nicoloso Barbara
Published: November 2023

Le pic de consommation des ressources fossiles et métalliques, le peak all, constitue un véritable enjeu pour la transition énergétique et le défi climatique. Le sujet de la raréfaction des ressources laisse place à celui de l’abondance face aux impacts en termes de consommations d’énergie et d’émissions de gaz à effet de serre de l’extractivisme. Les objectifs réglementaires internationaux et nationaux en matière de transition énergétique et lutte contre le dérèglement climatique sont clairs : nos consommations d’énergie doivent être réduites de moitié d’ici 2050. En venant renforcer les économies d’énergie résultant de l’efficacité énergétique et le développement des énergies renouvelables, la sobriété énergétique, ou maîtrise de la demande en énergie par des changements de comportements individuels et collectifs, permet de limiter les externalités négatives de nos modes de vie, de production, et d’échanges actuels et à venir sur la nature et le climat.

Amendement alcalin à base de boues de pâtes de sucrerie et d'argiles : application sur les résidus de la mine abandonnée de Kettara (Maroc)
Authors: Nfissi Samiha , Alikouss Saida , Zerhouni Youssef , Baroudi Zouhir , Samir Mohamed
Published: November 2023

Les rejets miniers sulfurés de la mine de Kettara (région de Marrakech) sont entreposés sur un socle schisteux très fracturé sur une superficie d’environ 16 hectares. Dans ce site, plus de 3 millions de tonnes de résidus sont stockés sur le sol sans aucune contrariété de leurs impacts sur l’environnement. Les minéraux acidogènes composant ces rejets, sous l’action de l’eau et de l’oxygène, génèrent du Drainage Minier Acide (DMA). Ce phénomène entraîne une acidité du milieu qui provoque la destruction de la flore et de la faune ainsi que la contamination des eaux souterraines. Ces rejets solides à fortes concentrations en métaux (As, Pb, Fe, Cu…), produisent des lixiviats très acides (pH ≤ 3) entrainant la solubilisation des sulfures et la libération des métaux toxiques qui polluent les ressources hydriques de la région. Afin d’atténuer le DMA à Kettara, un protocole d’amendement alcalin a été testé au laboratoire en utilisant les boues de pâte de sucrerie (Sludge Pulp of Sweets : SPS) et des argiles (Clays : Clys). Les matériaux choisis ont fait l’objet d’une caractérisation physico-chimique et minéralogique puis d’une série d’essais de lixiviation en mini-cellules d’altération. Ces essais ont montré que les pH des SPS et des Clys varient respectivement entre 6,1 et 8,5 et entre 6,7 et 9. Le potentiel neutralisant de ces matériaux, déterminé par la méthode Acid-Base Accounting, est de l’ordre de 878,5 Kg CaCO3/t pour les SPS et de 299 Kg CaCO3/t pour les Clys. Ces matériaux fins et alcalins ont donc un potentiel neutralisant assez élevé susceptible de réduire considérablement le DMA. Les SPS et des Clys, au vue de leur potentiel de neutralisation et leurs propriétés physico-chimiques, constitueraient d’excellents matériaux de base pour un amendement visant l’atténuation du DMA dans la mine abandonnée de Kettara.

Published: November 2023

В статті проведено дослідження впливу фінансової транспарентності на вартісні показники діяльності бізнесу. Метою роботи є дослідження теоретичних та практичних аспектів фінансової транспарентності, а також аналіз її впливу на вартісні показники бізнесу в системі корпоративного управління. Визначено, що на вартість компанії істотно впливають фактори її фінансової публічності та прозорості які формують корпоративну репутацію та рівень довіри споживачів та інвесторів. Прозорість визначається рівнем відкритості та якістю доступної інформації, пов’язаної з операціями компанії. Це охоплює не тільки фінансові звіти, але також управлінські процедури, дотримання етичних норм, взаємодію з зацікавленими сторонами та ключові рішення, прийняті на різних етапах розвитку підприємства. У статті детально аналізуються ці аспекти, надаючи глибше розуміння значення прозорості для бізнесу та її взаємодії з різними сферами управління та розвитку підприємств.

Стаття підготовлена за результатами дослідження, що фінансується за рахунок бюджетних коштів МОН України «Цифровізація та транспарентність публічних, корпоративних та особистих фінансів: вплив на інноваційний розвиток та національну безпеку» (реєстраційний номер: 0122U000774).

Published: November 2023

In the context of the expanding economy in Indonesia, the management of companies faces increased competition, necessitating effective strategies to stay competitive. Financial reports play a crucial role in evaluating a company's performance and aiding decision-making processes for both management and investors. Among the essential elements used to assess management performance in financial statements is profit, presented in the profit/loss statement. This study aims to provide empirical evidence on the effect of firm size and financial performance, proxied by profitability and leverage, on earnings management in mining companies listed on the Indonesia Stock Exchange during the period of 2016-2021. The research adopts a quantitative approach and utilizes secondary data from the selected mining companies. The population comprises mining companies listed on the Indonesia Stock Exchange, and the sample is obtained through purposive sampling, resulting in 66 data points from 11 companies over a 6-year period. Data analysis involves multiple linear regression, descriptive statistical tests, panel data regression model analysis, Common Effect Model selection test, classical assumption test, and multiple linear testing using Eviews version 11 for data processing. The research findings indicate that when considered together, Company Size and Financial Performance, represented by Profitability and Leverage, have a significant impact on Earnings Management. Specifically, Financial Performance, proxied by Profitability, is found to exert a notable effect on Earnings Management. However, the study reveals that Firm Size and Financial Performance, proxied by Leverage, do not significantly influence Earnings Management.

The modern business landscape is characterized by dynamic interactions between various financial indicators that influence a company's financial health and performance. This study aims to investigate the impact of growth, liquidity, and profitability on capital reserves. It is an associational quantitative study that utilizes secondary data. The present research adopts an associational quantitative approach, utilizing secondary data from a five-year period spanning from 2016 to 2020. The population of interest comprises basic and chemical industrial enterprises that are publicly listed on the Indonesia Stock Exchange. The study employs a robust combination of literature review and documentation techniques to collect pertinent data, creating a comprehensive foundation for analysis. To rigorously investigate the interplay of growth, liquidity, profitability, and their connection to capital reserves, the study employs advanced panel data regression analysis. The analysis reveals that growth exerts no discernible impact on cash on hand, suggesting that while expansion may drive other financial outcomes, it does not directly affect the immediate availability of capital reserves. Conversely, liquidity emerges as a crucial determinant, exhibiting a positive influence on cash on hand. This underscores the importance of maintaining a robust liquidity position, which enables companies to effectively manage day-to-day financial obligations and seize strategic opportunities. Furthermore, the study establishes a positive correlation between profitability and cash on hand. Companies that exhibit higher profitability are more likely to accumulate substantial capital reserves, reflecting a capacity to generate surplus funds even after accounting for operational expenses.
