На основе исследования рисков организации, производящей грузовой железнодорожный подвижной состав, предложен комплекс мероприятий, позволяющий снизить выявленные риски. Разработанный комплекс мероприятий по снижению рисков организации, производящей грузовой железнодорожный подвижной состав, имеет системный характер и позволяет тиражировать разработанную матрицу на любые аналогичные предприятия, так как структура комплекса включает наименование идентифицированных рисков; формулировку конкретной стратегии и мероприятий, способствующих снижению этих рисков; установленные сроки исполнения мероприятий и ответственных за их выполнение. Предложенные подходы к оценке эффективности деятельности по управлению рисками организации, а именно подход аналогий, подход на основе целей, подход на основе выгоды, подход на основе самооценки, позволяют оценить уровень системности этой деятельности, что открывает возможность реализации полноценного системного подхода к управлению рисками. Данные, полученные в результате исследования, имеют научный и практический характер, который проявляется в возможности их внедрения при создании системы управления рисками в организациях.

The article examines the organization’s risks, evaluates the organization’s risk management activities, and proposes an algorithm for developing measures to reduce them. Based on a study of the risks of an organization producing freight railway rolling stock, a set of measures is proposed to reduce the identified risks. The research methodology is based on a systematic approach to the objects and processes being studied, which determined the use of general scientific and special methods. The developed set of measures to reduce the risks of an organization producing freight railway rolling stock is systemic in nature and makes it possible to replicate the developed matrix to any similar enterprises, since the structure of the complex includes the name of the identified risks, specific strategies and activities to reduce these risks, terms for the implementation of activities and those responsible for their implementation. The proposed approaches to assessing the effectiveness of an organization's risk management activities, namely, the analogy approach, the goals-based approach, the benefit-based approach, and the self-assessment approach allow implementing a full-fledged systematic approach to risk management. The results of the study are of a scientific and practical nature, and can be applied when creating a risk management system in organizations. Key words: risks of an organization, manufacturer of railcar manufacturing products, identification and assessment of risks, risk reduction tools, risk management system.

PERAN GURU DALAM PEMBELAJARAN SEBAGAI WACANA PROFESIONALISME PENDIDIK (TINJUAN ANALISIS WACANA KRITIS)
Authors: Harsia Harsia , Madeamin Sehe
Published: February 2025

Guru adalah pendidik, yang menjadi tokoh, panutan, dan identifikasi bagi para peserta didik, dan lingkungannya. Oleh karena itu, guru harus memiliki  standar  kualitas  pribadi  tertentu, yang mencakup  tanggungjawab, wibawa, mandiri, dan disiplin.Sebagai pengajar, guru harus memiliki tujuan yang jelas, membuat keputusan secara rasional agar peserta didik memahami keterampilan yang dituntut oleh pembelajaran.Guru dapat diibaratkan sebagai pembimbing perjalanan (journey),yang berdasarkan pengetahuan dan pengalamannya bertanggungjawab atas kelancaran perjalanan itu
Proses pendidikan dan  pembelajaran memerlukan latihan keterampilan, baik intelektual maupun motorik, sehingga menuntut guru untuk bertindak sebagai pelatih. Guru adalah seorang penasehat bagi peserta didik, bahkan bagi orangtua, meskipun mereka tidak memiliki latihan khusus sebagai penasehat  dan dalam beberapa hal tidak dapat berharap  untuk menasehati orang.
Bahasa memang merupakan alat untuk berpikir, melalui pengamatan yang dilakukan dan menyusun kata-kata serta menyimpan dalam otak, terjadilah pemahaman sebagai hasil be;lajar. Hal tersebut selalu mengalami perubahan dalam setiap generasi, dan perubahan yang dilakukan melalui pendidikan akan memberikan hasil yang positif. Sebagai teladan, tentu saja pribadi dan apa yang dilakukan guru akan mendapat sorotan  peserta didik serta orang di sekitar lingkungannya yang menganggap atau mengakuinya sebagai guru.Sebagai individu yang berkecimpung dalam pendidikan, guru harus memliki kepribadian yang mencerminkan seorang pendidik. Tuntutan akan kepribadian sebagai pendidik kadang-kadang dirasakan lebih berat disbanding profesi lainnya
Dengan kesadaran bahwa ia tidak mengetahui sesuatu maka ia berusaha mencarinya melalui kegiatan penelitian. Usaha mencari sesuatu itu adalah mencari kebenaran, seperti seorang ahli filsafat yang senantiasa mencari, menemukan dan mengemukakan kebenaran.Sebagai  orang yang kreatif, guru menyadari bahwa kreativitas merupakan yang universal dan oleh karenanya semua kegiatannya ditopang, dibimbing dan dibangkitkan oleh kesadaran itu
Guru dan peserta didik bekerjasama mempelajari cara baru, dan meninggalkan kepribadian yang telah membantunya mencapai tujuan dan menggantinya  sesuai dengan tuntutan masa kini. Proses ini menjadi suatu transaksi bagi guru dan peserta didik dalam pembelajaran.

Authors: WIKTOROWSKA-JASIK Anna , SEK Joanna , KAUP Magdalena
Published: February 2025

The main objective of the research contained in the article is to analyse the structure of the market of energy suppliers for charging electric vehicles in Poland. Currently, many scientific publications deal with the topic of electromobility from the point of view of the available infrastructure, however, the issues of energy suppliers for charging vehicles are neglected. Therefore, special consideration was given to introducing the most important entities operating on the Polish market in the context of an attempt to determine their market share and the scope of services offered.

The first part of the article presents the current state of publicly available electric vehicle charging stations in Poland, along with a description of the most commonly used chargers. The year-on-year growth dynamics of publicly available charging points is presented. For example, comparing data for July of 2023 and 2024 in the year-on-year system, the increase was as high as 76%. In the second part of the article, a comparative analysis of energy suppliers in terms of their offer and capabilities was carried out, paying particular attention to the technical and organizational solutions they use. It was found that the market of energy suppliers focuses on the main five players. On the other hand, the market of operators, in addition to the three main players (ENEA, Orlen Charge and Tauron), is fragmented. Based on the analysis conducted, the dependencies and difficulties faced by energy suppliers to ensure an adequate level of service and the availability of charging infrastructure were identified.
Performance of RPL-based Wireless Sensor Networks Subjected to Selected Attacks
Authors: MACIEJKO Przemyslaw , KRYGIER Jaroslaw
Published: February 2025

The paper focuses on evaluating the performance of wireless sensor networks (WSNs) equipped with the Routing Protocol for Low-Power and Lossy Networks (RPL) that have been subjected to Blackhole, Sinkhole, Version Number and DIS Flooding attacks. In a WSN consisting of dozens of sensors, which are also nodes forwarding IPv6 traffic to a border node, the IPv6/6LoWPAN/IEEE 802.15.4 protocol stack was used. The indicated attacks were carried out in two scenarios. In the first, selected sensors were replaced with sensors with modified software, which enabled an attack on the RPL protocol. In the next scenario, intruder nodes were added to the network, which attached themselves to the existing network structure and thus carried out attacks on the RPL protocol. The article is oriented not to evaluate the effectiveness of the attacks in both scenarios, but to evaluate the performance of the sensor network during the success of each attack. Thus, it was possible to draw conclusions about such an organization of sensor network structures that will enable minimizing the effects of selected attacks in the context of maximizing network performance. Due to the fact that all of the aforementioned attacks were carried out simultaneously at different locations on the network, the degradation of the network resulted in a significant decrease in its performance. Nevertheless, thanks to the research performed, a number of recommendations were prepared to prepare a network that performs its tasks despite the success of individual attacks.

ABSTRACT
Every organization aspires for its people to advance towards managing quality, exceptional and outstanding performance in order to achieve optimal results. The work environment, job atisfaction and performance all contribute to an organization's success. This study investigated the impact of the physical work environment (x1) and non-physical work environment (x2) on job satisfaction (y) and performance (z). This type of research uses a quantitative method with a population of 425 and a significance threshold of 10%, yielding 81 samples that use the Slovin formula. SPSS Statistic 26 helps with descriptive analysis, data quality testing, multiple regression analysis and determinant coefficient analysis. The grand mean value of all variables is classified. We found the multiple regression equations y=11,796+0,391x1+0,248x2, and z=-0,108+0,004x1-0,005x2+1,006y. There is a positive and significant effect of x1 and x2 on y; there is no direct influence of x1 and x2 on z; y directly has a positive and significant effect on z; indirectly, x1 and x2 through y have a significant influence on z; x1 and x2 explain y to 41,4%, meaning another 58,6% is explained by other factors; z is explained by x1, x2, and y to 98,3%, with only 1,7% explained by other factors outside this research.

Abstract. We introduce Saudi Rainfall (SaRa), a gridded historical and near real-time precipitation (P) product specifically designed for the Arabian Peninsula, one of the most arid, water-stressed, and data-sparse regions on Earth. The product has an hourly 0.1° resolution spanning from 1979 to the present and is continuously updated with a latency of less than two hours. The algorithm underpinning the product involves 18 machine learning model stacks trained for different combinations of satellite and (re)analysis P products along with several static predictors. As a training target, hourly and daily P observations from gauges in Saudi Arabia (n=113) and globally (n=14,256) are used. To evaluate the performance of SaRa, we carried out the most comprehensive evaluation of gridded P products in the region to date, using observations from independent gauges (excluded from training) in Saudi Arabia as a reference (n=119). Among the 20 evaluated P products, our new product, SaRa, consistently ranked first across all evaluation metrics, including the Kling-Gupta Efficiency (KGE), correlation, bias, peak bias, wet days bias, and critical success index. Notably, SaRa achieved a median KGE — a summary statistic combining correlation, bias, and variability — of 0.36, while widely used non-gauge-based products such as CHIRP, ERA5, GSMaP V8, and IMERG-L V07 achieved values of -0.07, 0.21, -0.13, and -0.39, respectively. SaRa also outperformed four gauge-based products such as CHIRPS V2, CPC Unified, IMERG-F V07, and MSWEP V2.8 which had median KGE values of 0.17, -0.03, 0.29, and 0.20, respectively. Our new P product — available at www.gloh2o.org/sara — addresses a crucial need in the Arabian Peninsula, providing a robust and reliable dataset to support hydrological modeling, water resource assessments, flood management, and climate research.
Evaluating Dynamic Global Vegetation Models in China: Challenges in capturing trends in Leaf Area and Gross Primary Productivity, but effective seasonal variation representation

Published: February 2025

Abstract. Terrestrial ecosystems are crucial in mitigating global climate change, and Dynamic Global Vegetation Models (DGVMs) have become essential tools for simulating these ecosystems. However, uncertainties remain in DGVM simulations for China, highlighting the need to systematic evaluations of their dynamics across various time scales to enhance model performance. As such, we utilize reprocessed monthly MODIS Leaf Area Index (LAI) and Contiguous Solar-induced Fluorescence (CSIF) data as observational references to assess the long-term trends and seasonal variations of LAI and Gross Primary Production (GPP) simulated by 14 models (CABLE-POP, CLASSIC, CLM5.0, DLEM, IBIS, ISAM, ISBA-CTRIP, JULES, LPJ-GUESS, LPX, OCN, ORCHIDEEv3, SDGVM, and VISIT) in China from 2003 to 2019. Additionally, we evaluate the trends and seasonal variations of simulated LAI and GPP in response to environmental and climatic factors. Our findings indicate that: (1) While the overall trend of simulated LAI is captured, the spatial performance of simulated LAI and GPP is poor, with underestimation in forested areas, overestimation in grasslands, and misestimation in croplands; (2) The models misestimate the simulated LAI and GPP responses to changes in environmental factors, and their inaccuracy in capturing anthropogenic impacts on vegetation dynamics. We indicate that the main reason for the model's misestimation is that the model's understanding of the CO2 fertilization effect is inadequate, and thus fails to simulate the vegetation response to CO2 concentration. (3) Despite these issues, the models can effectively capture the seasonality of LAI and GPP in China, largely due to their robust representation of seasonal responses to climate factors.
A Sentinel-2 machine learning dataset for tree species classification in Germany
Authors: Freudenberg Maximilian , Schnell Sebastian , Magdon Paul
Published: February 2025

Abstract. We present a machine learning dataset for tree species classification in Sentinel-2 satellite image time series of bottom-of-atmosphere reflectance. It is geared towards training classifiers but is less suitable for validating the resulting maps. The dataset is based on the German National Forest Inventory of 2012 as well as analysis-ready satellite imagery computed using the Framework for Operational Radiometric Correction for Environmental monitoring (FORCE) processing pipeline. From the National Forest Inventory data, we extracted the tree positions, filtered 387 775 trees in the upper canopy layer, and automatically extracted the corresponding bottom-of-atmosphere reflectance time series from Sentinel-2 L2A images. These time series are labeled with the corresponding tree species, which allows pixel-wise classification tasks. Furthermore, we provide auxiliary information such as the approximate tree position, the year of possible disturbance events, or the diameter at breast height. Temporally, the dataset spans the years from July 2015 to the end of October 2022, with approx. 75.3 million data points for trees of 48 species and 3 species groups as well as 13.8 million observations for non-tree backgrounds. Spatially, it covers the whole of Germany. The dataset is available at the following DOI (Freudenberg et al., 2024): https://doi.org/10.3220/DATA20240402122351-0.
Mapping the global distribution of lead and its isotopes in seawater with explainable machine learning
Authors: Olivelli Arianna , Arcucci Rossella , Rehkämper Mark , van de Flierdt Tina
Published: February 2025

Abstract. Lead (Pb) and its isotopes are a powerful tool to study the pathways of Pb pollution from land to sea and, simultaneously, investigate biogeochemical processes in the ocean. However, the scarcity and sparsity of in situ measurements of Pb concentrations and isotope compositions do not allow for a comprehensive understanding of Pb pollution pathways and biogeochemical cycling on a global scale. Here, we present three machine learning models developed to map seawater Pb concentrations and isotope compositions leveraging the global GEOTRACES dataset as well as historical data. The models use climatologies of oceanographic and atmospheric variables as features from which to predict Pb concentrations, 206Pb/207Pb, and 208Pb/207Pb. Using Shapley Additive Values (SHAP), we found that seawater temperature, atmospheric dust and black carbon, and salinity are the most important features for predicting Pb concentrations. Dissolved oxygen concentration, salinity, temperature, and atmospheric dust are the most important features for predicting 206Pb/207Pb, while atmospheric black carbon and dust, seawater temperature, and surface chlorophyll-a for 208Pb/207Pb. Our model outputs show that (i) the surface Indian Ocean has the highest levels of pollution, (ii) pollution from previous decades is sinking in the North Atlantic and Pacific Ocean, and (iii) waters characterised by a highly anthropogenic Pb isotope fingerprint are spreading from the Southern Ocean throughout the Southern Hemisphere at intermediate depths. By analysing the uncertainty associated with our maps, we identified the Southern Ocean as the key area to prioritise in future sampling campaigns. Our datasets, models and their outputs, in the form of Pb concentration, 206Pb/207Pb, and 208Pb/207Pb climatologies, are made freely available to the community at Olivelli et al.

Published: February 2025

To address diversity-sensitive higher education, we provide the first results exhibiting the importance of the use of German Sign Language (Deutsche Gebärdensprache, DGS) in lecture videos of elementary statistics courses. We examined whether deaf individuals preferred lecture videos in DGS over those with captions. Results from quantitative and qualitative analyses on the basis of survey data and interview material in DGS indicate a clear preference for teaching materials in DGS.

Authors: DE VASCONCELOS SANTOS EMILY , FERREIRA DA SILVA ANA FLÁVIA , DE OLIVEIRA SOUZA LEANDRO
Published: February 2025

This study examines, with focus on statistical education, how intersectionality appears in didactic tasks for Brazilian school education, developed by IBGEeduca, an educational platform organized by IBGE (Brazilian Institute of Geography and Statistics). In this study, intersectionality was used as an analytical tool to help understand and explain the complexities of the world that impose social injustices through interrelationships of power categories. The documentary methodological approach adopted in this research is part of a doctoral research project. The criteria for choosing the analyzed tasks were based on the authors' perception of the intersectional categories in the examined pedagogical proposals. We present an interpretative analysis of an IBGEeduca proposal from the theoretical perspective of critical statistics education. This investigation revealed several themes related to contemporary problems present sporadically in the proposed activities, requiring greater scrutiny of the hidden intersections among the categories exposed in the proposals. The findings of this Brazilian case study could spark conversations about how statistics teachers can use tasks to help students understand concepts of inequity and social injustice.

REFORMA AGRÁRIA E PROPRIEDADE PRIVADA NO BRASIL: DA CONSTITUIÇÃO DE 1946 AO CONSTITUCIONALISMO DE 1988
Authors: Possas Thiago Lemos
Published: February 2025

O presente artigo busca reconstruir o debate acerca da reforma agrária e da propriedade privada no Brasil, tendo como recorte histórico o período compreendido entre a Constituição da República de 1946 e a conformação atual dada aos mencionados institutos pelo constitucionalismo democrático consagrado em 1988. O artigo revisita o impacto de certos acontecimentos históricos nacionais, como o Golpe Militar de 1964, destacando os efeitos legislativos e mesmo factuais ocasionados na reforma agrária. Enfrentam-se, ainda, questões que se colocam na contemporaneidade como a relevância de uma política agrícola adequada à efetivação da reforma agrária, bem como a correta consideração da consagrada “função social da propriedade” e os desdobramentos causados pela disputa sobre a significação desta expressão. Defende-se a necessidade de se “dessacralizar” o instituto da propriedade como único meio de realização de uma reforma feita em consonância com o constitucionalismo atual.

Calcium silicate-based sealers have emerged as a transformative innovation in endodontics, offering solutions to longstanding challenges such as microleakage, biocompatibility, and durability. These sealers demonstrate exceptional adaptability due to their hydraulic setting properties, ensuring tight seals in moist environments and reducing micro-gaps commonly associated with traditional materials. Their bioactivity, characterized by the release of calcium ions and hydroxyapatite formation, promotes periapical tissue healing and enhances the interface between dentin and the sealer, contributing to long-term treatment success. High alkalinity during setting provides sustained antimicrobial activity, effectively inhibiting bacterial proliferation within the root canal system. This property, coupled with low solubility and resistance to degradation, ensures stability and reliability even under challenging clinical conditions. Comparative studies reveal that calcium silicate-based sealers outperform traditional alternatives, such as epoxy resin and zinc oxide-eugenol sealers, in key performance metrics, including sealing ability, biocompatibility, and post-treatment outcomes. Clinically, these sealers are compatible with various obturation techniques, simplifying application while maintaining efficacy in sealing complex canal anatomies. Patients treated with calcium silicate-based sealers report lower incidences of postoperative pain, attributed to their anti-inflammatory properties and enhanced healing potential. Emerging research continues to refine their formulations, addressing limitations like prolonged setting times and optimizing handling properties. The integration of calcium silicate-based sealers into routine endodontic practice signifies a paradigm shift, driven by their ability to improve clinical outcomes and reduce failure rates. As material advancements progress, these sealers hold promises for broader applications in complex cases, further enhancing the predictability and success of root canal treatments. Their superior performance establishes them as a cornerstone in modern endodontic care, addressing both current and future challenges in the field.
