Published: December 2024

The article presents a justification of the marginal boundaries of an open-pit mine using the Pavlik deposit as a case study. The authors performed an analysis and evaluation of the methodology to optimize the open-pit boundaries with account of the economic, environmental and social factors. The Lerchs-Grossmann algorithm is used as the main method to define the final outlines of the open pits. The Lerchs-Grossmann algorithm provides the planning flexibility due to its ability to integrate dynamic data and subsequently adjust the open-pit boundaries. The model is used to calculate the value of each elementary block, defined as the profit earned from selling the extracted mineral, minus the department costs of mining, ore processing and general factory expenses. As a result of the optimization based on the selected algorithm, the optimal set of blocks was formed, which represents the shape of the optimal open-pit for the deposit development. This method makes the use resources more efficient, avoiding the collapse of slopes and other dangerous events, which directly affects the occupational safety. At the same time, the result of optimization calculations is an auxiliary tool for justification of the optimal boundaries, based on the fact that the final solution is established by comparing the boundary and contour stripping ratios.
Automatic tuning of the pooling operation in convolutional neural networks for coal rock classification
Authors: Kozlova O.A. , Kitov V.V.
Published: December 2024

Convolutional neural networks are used to automate image processing tasks such as classification, segmentation, object detection, style transfer, etc. These networks are actively applied in coal mining industry for automatic classification of coal rocks with high accuracy based on raw images. Accurate classification of the coal rocks is important for coal quality assessment, optimization of coal mining, preparation and processing. The main mathematical operations of convolutional networks are convolution and pooling. The paper discusses a generalization of the pooling operation. Usually the type of pooling is specified in advance by some aggregation operation, i.e. the average pooling or max pooling. The size of the aggregated area is also specified in advance. The type of pooling and the size of the aggregated region significantly affect the quality of coal-bed image processing. This paper proposes several parametric generalizations of the pooling operation, which cover the average and max pooling as special cases. A parametric generalization is also proposed for max pooling, which allows to vary the size of the aggregation region. Parameters of the proposed pooling generalizations are automatically trained along with the rest of the network weights.

Influence of the spatial variability of rock strength on the rock burst hazard in rock masses
Authors: Ilyasov B.T. , Ozhiganov I.A. , Trofimov A.V.
Published: December 2024

The The reliability of existing criteria and methods for predicting the hazard of rock burst occurrence is currently assessed as insufficient. Not all of the deep and large-scale deposits that are characterized as rock burst prone and hazardous by the current regulatory guidelines are experiencing rock bursts. This paper focuses on critical examination of the rock burst hazard in the rock masses, rather than solely relying on individual rock samples. The article proposes a hypothesis concerning how the homogeneity of a rock mass influences its brittleness and the rock bursts, referencing foundational research that supports this concept. A thought experiment is presented to clarify how the homogeneity of a rock mass can directly influence its brittleness and the rock burst hazard. In order to systematically assess the homogeneity of a rock mass, the proposed methodology involves quantifying the coefficient of variation of strengths in a localized rock mass zone under uniaxial compression and tension. A comprehensive evaluation was conducted to explore the correlation between the rock burst hazard of a rock mass and the coefficient of variation for compressive and tensile strengths, drawing upon empirical data collected from 44 rock varieties across 18 distinct mining locations. The study is concluded by revealing a correlation between the rock burst of rock masses and the coefficient of variation. Suggested threshold values for the coefficient of variation are provided, indicating the rock burst hazard of rock mass in situ. Furthermore, the influences of various factors on the coefficient of variation and of rock burst hazard are examined.

Authors: Zaka Istifatun
Published: December 2024

Enhancing the speaking skills of BIPA learners can be effectively achieved through the implementation of routines and patterns. However, this is often not paid attention to in foreign language learning, including BIPA, because it is directly at the creative language stage. For this reason, research is needed on whether foreign speakers' Indonesian speaking skills will improve if the learning process is carried out through routines and patterns. This qualitative descriptive study investigates the instructional environment of BIPA students at Yogyakarta State University, with a focus on the Yunan class. Data were collected from interactions between the instructor and BIPA students. The findings indicate that the use of routine and patterned expressions by instructors facilitates implicit language acquisition, allowing learners to internalize Indonesian through structured classroom routines. These routines and patterns play a crucial role in fostering and maintaining social interactions and optimizing communicative competence in Indonesian.

Published: December 2024

The widespread use of deepfake technology in recent years has made it extremely difficult to differentiate between real and fake images, usually AI-generated images. Effective detection techniques are desperately needed because one can generate fake images and spread them with ease. This research paper examines how effective the SWIN Transformer, a new transformer-based architecture, is for detecting deep fake images. The foundation of the suggested detection framework is an architecture made up of bottleneck, encoder, and decoder parts which is a type of SWIN transformer. It uses various self-attention mechanisms and advanced features to analyse the images closely whether it is a real image or a deepfake one. It relies on the concept of shifted windows during the processing of the images and is considered more effective than the traditional CNN methods. Our test results show how well the SWIN Transformer-based method performs in precisely recognizing deep fake images. The accuracy is found to be 97.91\% for CelebDF dataset and 95.715\% for FF++ dataset. The AUC for the newly modelled SWIN transformer is 0.99 and 0.9625 for CelebDF and FF++ datasets respectively. The Log Loss was calculated to be 0.034 for CelebDF dataset and 0.1573 for FF++ dataset. The proposed methodology not only enhances the accuracy of detecting manipulated images but also offers potential for scalable and efficient deployment in real-world scenarios where the proliferation of deepfakes presents significant challenges to maintaining trust and authenticity in visual media.

Methods for constructing models of two-dimensional probability distributions are considered. The need to take into account independent Gaussian noise when using multidimensional models of non-Gaussian impulse noise that have significant empirical prerequisites has been determined. Potential effectiveness of suppressing such noise found. The method used to obtain multi-dimensional models of non-Gaussian noise is to represent the noise as a result of filtering the Poisson pulse stream. No model singularity conditions defined. It has been shown that to build multidimensional models of non-singular non-Gaussian impulse noise, it is necessary to introduce Gaussian noise independent at the considered dimension. Another option is to use a filtered impulse process with a correlation function with an initial quadratic section. The potential processing gain was estimated taking into account the relationship between atmospheric noises readings relative to the method of their amplitude suppression, which does not exceed 4...8 dB.

Published: December 2024

Computer-based assessment (CBA) is a top-rated tool for conducting assessments, mapping learning outcomes, and selecting new candidates. Research that examines the development and use of CBA is also increasing from year to year, so without bibliometric analysis, it would be quite challenging to keep up with all of these studies. This study aims to clarify the status and world trends in CBA research around the world. Bibliometric analysis was performed using bibliometrix based on 2,020 articles published in Scopus from 1982 to 2023 (data update time on 5 January 2024). This bibliometric analysis identified the state of research publications, scientific productivity, the network state of research publications, and CBA research priorities and directions going forward. Results show that research on CBA has grown rapidly, with the highest number of publications in 2022, with the USA being the most productive country. Greiff is the most prolific and Wise is the most impactful author. The journal with the highest impact is “Computers and Education”. These findings also indicate that research themes that show research potential due to their high relevance to CBA but are still little studied are those related to “regression analysis”, “automation”, “information technology”, “assessment”, “motivation”, “quality control”, “problem solving”, “online systems”, “decision making”, and “teaching”.

Published: December 2024

Information and communication technologies (ICT) can help increase teachers’ abilities and, as a result, the learning of new cohorts of students who, in the age of mass higher education, enter university classrooms less prepared. Although ICT-based teacher training initiatives are well-known, there is little proof that the results are useful for students. This research aimed to study the efficiency of a teacher preparation program that considered the usage of ICT, with follow-up in the ensuing years. The sample consisted of all students enrolled at the Universidad Tecnológica Metropolitana of Chile from 2017 to 2022. The method of analysis grade point average was compared using a t-test to detect significance each year. The results show that in 2017–2022, students who had courses with trained instructors performed better on tests than students who had classes with untrained teachers on average. Also, it has been found that in science, technology, engineering, and mathematics (STEM) areas instructors receive training that is generally more effective than non-STEM teachers. Consequently, women in STEM and non-STEM fields perform better when their teachers are qualified.

Authors: Hellgren Jenny M. , Bergqvist Ewa , Österholm Magnus
Published: December 2024

Argumentation is a key skill in most school subjects and academic disciplines, including mathematics and science. It is possible that similarities and differences between how argumentation is expressed in different subjects can contribute to, or disrupt, students’ transferrable argumentation skills. The purpose of this study is therefore to increase the understanding of such similarities and differences concerning the use of argumentation in mathematics and science texts. To reach this goal, the study compares argumentation with a focus on argumentation markers and argumentative structures in first-semester university textbooks in mathematics, chemistry, and biology. Results show that common linguistic argumentation markers in mathematics and science textbooks include for example because, if, thus, so, and therefore and that there is significantly more argumentation in the mathematics textbook compared to the science textbooks. Further, the results indicate differences in patterns of how argumentation is used, including for example that the mathematics textbook contains more complex argumentation compared with the chemistry textbook. Thereby, the subject-specific languages in the disciplines have the potential to offer students different examples of argumentation.

Authors: Mardones Vallejos Vicente Antonio , Lefebvre María Gisela , Maldonado Mario Gabriel
Published: December 2024

The objective of this research is to establish the effects produced by human activities on the phytolithic composition within a circular structure located at the Yasyamayo site (Yocavil valley, Tucumán, Argentina) during the Late Period (1000-1480 AD). To achieve this, the phytolithic assemblage of this structure was analyzed and compared with those from a stratigraphic sequence without anthropic activity and other from an agricultural terrace. The results showed some differences between the compared sets and, together with available stratigraphic and geochemical data, support the hypothesis of the residential use of the circular structure, perhaps as an agricultural outpost, and reaffirmed the agricultural function of the cultivation terrace. Additionally, paleoenvironmental conditions reinforced for a drier pre-occupational stage than the current conditions were reaffirmed, coinciding with the Medieval Climatic Anomaly. The presence of an arid and semi-arid paleoenvironment with some humid fluctuations was observed for the post-occupational stage, coinciding with the Little Ice Age (1300-1850 AD).
Evaluation of Occupational Health and Safety Management System Performance in Shipyard Businesses with FAHP and FPROMETHEE Methods
Authors: Yorulmaz Murat , ÖZTÜRK Mehmet Arif
Published: December 2024

Shipyards are places where new ships are built, routine and mandatory maintenance and dismantling of ships are carried out and a wide range of work equipment and chemicals are used during these processes. The fact that most of the world is covered with water and that maritime transportation is advantageous compared to other types of transportation brings maritime transportation to the forefront. This situation also leads to an increase in work intensity in shipyards. Therefore, occupational health and safety (OHS) practices are also important in shipyards. In this context, this study aims to evaluate the OHS Management System (OHSMS) performances of shipyard enterprises and to rank the shipyard enterprises selected as alternatives according to their OHSMS performances in line with the determined criteria. In the first stage, five main and 16 sub-criteria as OHSMS performance criteria and five alternative shipyard enterprises were identified through literature research. In line with the expert opinions, the weights of the criteria were found with the Fuzzy Analytic Hierarchy Process (FAHP) method, one of the multi-criteria decision-making methods, and the alternative priority order for the criteria was determined with the Fuzzy PROMETHEE (FPROMETHEE) method using the results obtained from the FAHP method. As a result of the analysis, the main criterion "Management Review" was determined as the criterion with the highest weight ratio. As a result of the operations carried out with the criterion weights determined by FAHP, Shipyard 3 alternative was ranked first in terms of OHSMS performance in the priority ranking made by using FPROMETHEE method. In this study, OHSMS performance evaluation in shipyard enterprises has been carried out by using FAHP and FPROMETHEE methods, which are multi-criteria decision-making methods, and the findings have contributed to the shipyard sector and the literature.

Authors: Načinović Tino , Vukelić Goran , Mihaljec Benjamin , Pozder Ljubomir
Published: December 2024

This study investigates the effects of seawater exposure on the crashworthiness of two types of carbon/epoxy composite tubes under quasi-static compression. Carbon/epoxy composites, widely used in maritime structures due to their high strength-to-weight ratio and corrosion resistance, may experience altered mechanical properties when exposed to harsh marine conditions. To evaluate these effects, quasi-static crushing tests were conducted on composite tubes after a one-month exposure to natural seawater. Composite tubes were manufactured using hand layup and prepreg technique. By analyzing the behavior of these composite structures under controlled compression, the study aims to provide insights into their structural integrity in marine environments. Results indicate a significant impact of seawater exposure on the crashworthiness of carbon/epoxy composites. The maximum tensile force is considerably lower after the exposure, and hand layup specimens generally withstand the exposure much better than prepregs. The findings contribute to a deeper understanding of material behavior in marine applications, offering practical guidelines for designing and maintaining composite-based maritime infrastructure.

Published: December 2024

Energy supply is a critical variable affecting modern life. Indonesia has many renewable energies sources and one of them is ocean current. Savonius turbines, which are effective in low-speed currents, have been widely studied in their vertical form, but there has been little progress on cross-flow Savonius turbines. The turbine performance is investigated in this study by observing the behaviour caused by the influence of depth immersion, given that the surface of the submersible medium and the surface based can influence the turbulence caused. Therefore, the cross-flow Savonius turbine will be placed in three different depth conditions: 0.33H; 0.5H and 0.66H. Analysis is done with Computational Fluid Dynamics (CFD) software. The turbine's rotation direction is also set in two conditions (clockwise and counterclockwise). All these scenarios result that turbine with 0.66H and clockwise condition gives the highest results with Cp value at 0.249. The vortices flow pattern created by the clockwise configuration tends downward, in contrast to the counterclockwise which points upward. The cross-flow Savonius turbine works optimally in low TSR where its performance is greatly affected by torque.

Published: December 2024

Identity is always intertwined with collective identity and the surrounding natural environment, and it is the fundamental foundation that defines who they are to the surrounding nature. In the context of decision-making, Mutis Timau National Park shows that a lack of voice in Indigenous peoples is accommodated and a lack of identity recognition, but only involves specific individuals selectively. This paper is based on an explanatory case study, and the findings of this study reveal the importance of space for better environmental policy design, especially those guided by collaborative action in environmental decisions by accommodating the voices of indigenous leaders or community leaders from various clans fairly. Environmental communication with respect for culture and identity recognition will enhance collaboration and support the effectiveness of nature conservation and socio-cultural sustainability. The theoretical contribution of this research corroborates a significant contribution to the environmental communication literature and offers a practical framework contribution to be applied to inclusive communication strategies in a global context.

Published: December 2024

Background: Obsessive-compulsive disorder (OCD) is associated with an increased risk of cardiometabolic disorders. We developed a lifestyle intervention, named LIFT, aimed at improving lifestyle habits and reducing cardiometabolic risk factors in individuals with OCD. Aims: 1) To establish the feasibility and acceptability of LIFT; 2) to evaluate its preliminary efficacy; and 3) to explore individuals’ experiences of participation. Method: Individuals with OCD and at least 3 cardiometabolic risk factors (e.g., physical inactivity, unhealthy diet, overweight/obesity, dyslipidemia) were offered LIFT, consisting of one individual session to set individual goals, six educational group sessions, and 12 exercise group sessions, delivered over 3 months. We collected baseline, post-intervention, and 3-month follow-up measures. Preliminary efficacy variables were analyzed using linear mixed models and within-group effect sizes. Qualitative interviews were also conducted. Results: Out of 147 screened individuals, 25 were included in the study (68% women, mean age 37.4 [SD=10.9]). Credibility and satisfaction were high, attrition rates were low, and the program was generally safe. However, recruitment and adherence to the intervention were challenging. Statistically significant improvements were observed in dietary habits, alcohol consumption, stress, OCD symptom severity, and general functioning, with within-group effect sizes ranging from 0.27 to 0.56. No changes were observed in physical activity, sleep or any physiological or laboratory measures. Conclusions: Overall, LIFT was a feasible intervention for individuals with OCD. Effects on lifestyle habits, mental health, and functioning are promising. Randomized controlled trials are needed to evaluate its efficacy and cost-effectiveness.

Refugee children face difficult transitions from their home nation to their host one. Refugee girls are at heightened risks of experiencing inequity and lowered wellbeing. While social-emotional learning (SEL) is one way to support children in developing social-skills and wellbeing, previous research suggests it is less effective for refugee girls. This study interviewed teachers who have experience teaching SEL to refugee girls. Findings showed three themes: Structural Barriers, Unique Challenges for Refugee Girls, and Narratives of Integration and Assimilation all influence learning and practice. This study recommends actions that could improve refugee girl’s classroom experiences and integration into the UK.

This study analyzes the feasibility of implementing the Government Purchase Price (HPP) plus 20% incentive policy in Badung Regency to support food security and improve farmers' welfare. This study uses a triangulation method involving surveys of farmers, in-depth interviews with officials and experts, and secondary data analysis to understand the impact of incentive policies on income stability and local food production. The results show that this incentive has the potential to increase farmers' income by up to 18%, provide a more stable price guarantee, and encourage the interest of the younger generation to be involved in the agricultural sector. However, the main challenges in implementing this policy include funding sustainability, supervision effectiveness, and coordination between agencies. Based on these findings, this article provides recommendations for policy strengthening, including diversification of funding sources, application of technology in the surveillance system, and increased socialization among farmers. This research is expected to be the basis for local governments to design more effective and sustainable incentive policies to strengthen the agricultural sector and food security in areas that depend on the tourism sector, such as Badung Regency.

Randomized controlled trials are the gold standard for evaluating internet-based interventions (IBIs). However, their value depends on whether the estimated treatment effect accurately reflects its intended meaning. Unfortunately, this is not always the case. Decisions addressing so-called intercurrent events, such as treatment discontinuation, can shift effect interpretations. For instance, imputing data for those who discontinued the IBI instead of collecting follow-up data can shift the meaning from "the effect of simply providing individuals access to the IBI" to "the effect under the hypothetical scenario in which all individuals complete the IBI." To control the substantive meaning of the effect estimate, it is essential to clearly define the estimand, i.e., to provide a detailed and systematic description of the intended effect. A well-defined estimand justifies trial design decisions, including assessment and data-analytic strategies. Though widely adopted in pharmaceutical research, the ICH E9(R1) Addendum on Estimands and Sensitivity Analysis remains unrecognized in IBI research. Yet, its principles can improve research quality and reporting of trials studying the effects of IBIs. This manuscript introduces the addendum to IBI researchers by (1) explaining estimands and their five defining attributes, (2) emphasizing intercurrent events' role in the interpretation of treatment effects and strategies for handling them, (3) relating estimands to concepts like intention-to-treat and per protocol analyses, and (4) illustrating their application in two exemplary trials. We discuss how estimands inform study design, analysis, and reporting, offering practical recommendations for IBI research. We conclude that estimands are essential for investigating treatment effects in IBIs.
Bringing academia within its safe and just space: reflections on activating scientists
Authors: Urai Anne E , Kelly Clare
Published: December 2024

While academic climate activism is on the rise, most universities and scientific communities remain woefully underprepared to deal with the ‘wicked’ problems of climate change and biodiversity loss. Using Kate Raworth’s Doughnut Economics framework, we previously proposed a vision of academia that respects human and planetary boundaries (Urai and Kelly, 2023), offering a call to action that starts with culture change in scientific communities. Here, we reflect on the origin of our ideas and on the process of developing a participatory workshop that aims to catalyze the process of culture change. To encourage independent dissemination and wider engagement, we provide a set of best practices for hosting the workshop. Finally, we reflect on the value of such bottom-up approaches in academia, theories of change, and a vision for a way forward.

BackgroundInteroception, the sensing, awareness and regulation of physiological states, is crucial for wellbeing and mental health. Behavioural interventions targeting interoception exist, but Randomised Control Trials (RCTs) testing efficacy remain limited. The present, preregistered (ISRCTN16762367) RCT tested the novel Interoceptive iNsight and Metacognitive Efficacy beliefs (InMe) intervention. InMe uses slow-breathing and cardiac biofeedback during stress to train interoceptive self-efficacy beliefs and improve self-reported interoception.Methods Healthy participants aged 18-30 years with low self-reported interoception were randomly assigned (1:1) to the InMe intervention (n=50) or an active control (guided imagery; n=52). Participants blinded to allocation were stratified by gender and disordered eating. Assessments included baseline (T0), post-intervention (T1), and 7-8 weeks post-intervention (T2). The primary outcome was the “Adaptive Interoception” factor of the Multidimensional Assessment of Interoceptive Awareness questionnaire. Results Both arms improved in the primary outcome at T1 (InMe:adjusted M difference=5.76; 95%CI[-0.03;11.56], p=0.05; Control:adjusted M difference=7.90; 95%CI[1.92;13.87], p=0.002; Marginal R2=0.09). However, only InMe sustained this improvement at T2 (InMe:adjusted M difference=9.25, 95%CI[3.37;15.13], p<0.001; Control:adjusted M difference=2.94, 95%CI[-3.07; 8.96], p=0.72), as indicated by a significant Time*Arm interaction (b=6.31; SE=2.92, 95%CI[0.56;12.05], p<0.03; Marginal R2=0.12). Secondary outcomes showed a reduction in disordered eating scores across both arms at both time points (T1:b=-1.44, SE=0.37, 95%CI[-2.17;-0.71], p<0.001; T2: b=-1.05, SE=0.37, 95%CI[-1.79; -0.32], p=0.005). Conclusion The InMe intervention selectively improved self-reported interoception at follow-up but did not outperform the Control for secondary outcomes. Future research should explore its efficacy in clinical populations alongside complementary therapies.
Academic novels on research integrity
Authors: Bouter Lex
Published: December 2024

Fiction books on aspects of research integrity can be a valuable supplement to normative guidelines on how research should be done. They provide concrete examples of violations of codes of conduct. Their narratives sketch fictional cases of research misconduct and questionable research practices, and the circumstances under which they can occur. Novels can realistically depict the dilemmas scholars need to navigate in an accessible way that readers can relate to both intellectually and emotionally. This may help them to reflect on what a good researcher is and what academic scholars can do to stay close to that ideal. A sample of 31 novels from the last 100 years is described with special attention to the research integrity themes and the drivers of the depicted problems the books contain. These novels may be used in research integrity training as a method to evoke individual reflection or to inspire group discussion.
