Authors: Bielikov A.S. , Strezhekurov Yu.E.
Published: February 2025

Problem statement. In petrochemical, metallurgical, and glass production industries where high-temperature technological processes are employed, there is a problem of overheating of workers due to significant thermal loads. When certifying workplaces, there is a need to study and verify the impact of heat flow on humans. Therefore, there is a need for the development or modernization of devices for assessing thermal radiation stress in workplaces and conducting research in laboratory conditions close to real production situations, taking into account atmospheric factors, the geometry of the premises, the geometry of primary and secondary IR radiation sources, and the temperature of radiation sources. When certifying workplaces, there is a need to study and verify the impact of heat flow on humans. The main objectives include –  Modernization of an infrared camera for determining and visualizing, by express method, not only the temperature of the radiation source but also the thermal impact of high-temperature equipment on a worker in real conditions. The main tasks include: developing a functional diagram, designing the installation, and creating an algorithm to determine heat flow considering factors influencing the spread of IR radiation. Modernization of an infrared camera for determining and visualizing, by express method, not only the temperature of the radiation source but also the thermal impact of high-temperature equipment on a worker in real conditions. Conclusion. The modernized thermal camera enables the measurement of temperature distribution on the examined surface, the intensity of thermal radiation, as well as the distance to the object. It allows for simultaneous data collection on temperature and its changes over time in the camera's coverage area. Visualizing the distribution of heat flow on the screen for real-time interpretation; Ensuring measurement accuracy of 1 °C and a resolution of 10 cm at a distance of 10 m. The intensity of the thermal flux on the surface of the radiation source captured by the thermal camera can be displayed as both an integral value of the entire surface and grouped temperature values by sections. This significantly expands the functionality compared to traditional heat flux meters.

The post-war recovery of Ukraine will require an increase in the scale of production of rolled metal for the construction industry. The use of high-strength steels in the construction industry is the main reason for the emergence of increased requirements for these steels. At the same time, it should be noted that since the 80s of the last century, foreign manufacturers have been producing rolled metal for building metal structures according to technological schemes that include the use of accelerated cooling. The use of this particular technology makes it possible to achieve a higher level of operational properties (compared to classical controlled rolling) by replacing the pearlite phase in the structure of the rolled metal with a dispersed bainite component. Therefore, the task of researching the morphological features of the structural state, which is formed in low-carbon, low-alloy steels when using accelerated cooling in the technological scheme of production, is relevant. Purpose of the article. study of the morphology of structural components that are formed in low-carbon, low-alloy steels as a result of the action of intermediate and/or shear mechanisms of transformation of supercooled austenite. Conclusion. The morphology of the structural components that are formed in low-carbon, low-alloy steels as a result of the action of the intermediate and shear mechanisms of transformation of supercooled austenite has been studied. It was established that heat treatment in the temperature range of 550...450 °С with a holding time of 20 minutes leads to the formation of bainite of different morphological forms (upper bainite and acicular ferrite) and rack dislocation martensite (observed at a holding temperature of 450 °С) in the structure of low-carbon, low-alloy steels. With the use of microdiffraction analysis, it is shown that the boundary between two colonies of upper bainite has a structure that corresponds to the boundaries of a special type. Combined analysis of the microdiffraction and dark-field data showed that only residual austenite is found between the ferrite rails in the acicular ferrite packets (holding temperature 500 °C). Along with this, the carbonitride phase is also present in the colonies of rail dislocation martensite between the rails simultaneously with residual austenite. The conducted set of studies showed that the differences in the morphology of the structural components, which are formed during exposure in the temperature range of 550...450 °C, are caused, first of all, by the difference in the speeds and, as a result, the limitations of the crystal lattice shift processes. The higher the transformation temperature, the greater the diffusion activity of atoms, the lower the rate of shear transformation of γ-Fe into α-Fe.

Published: February 2025

This study aims to provide empirical evidence of the influence of corporate governance characteristics on cash holding. The population in this study is all public companies listed on the New York Stock Exchange (NYSE) for the 2020-2022 period. Sample selection was carried out using the purposive sampling method. Based on the sampling, observations were obtained as many as 568 companies-year. In this study, cash ownership is a dependent variable measured by cash and cash equivalents to total assets. Meanwhile, the independent variables of governance characteristics in this study consist of gender diversity measured by the number of female boards in the company, the size of the Board measured by the number of boards in the company, and board meetings measured by the number of meetings conducted by the board. The results of the study found empirical evidence that gender diversity has a positive and significant effect on cash holding. Meanwhile, the size of the Board and the Board meeting have no effect on cash holding. The implication of the results of this study is that the diversity of the Board mitigates managers' decisions in cash management.

Published: February 2025

This study investigates the impact of constructivist teaching methods on achievement and misconceptions in mechanics, with a focus on gender differences. The research involved 88 first-year physics students enrolled in the physics teacher training program. Using a quasi-experimental design, students were divided into experimental (constructivist teaching) and control (traditional teaching) groups, with each group completing a pre- and post-test to assess changes in understanding and misconceptions around key mechanics concepts, particularly the concept of force. Results reveal that the constructivist intervention significantly improved achievement scores, especially for female students, thus reducing the gender gap in physics achievement. However, persistent misconceptions were observed in specific, abstract topics, such as motion in frictionless environments and rocket propulsion, which were less effectively addressed by the constructivist approach alone. These findings contribute to the literature on gender-sensitive instructional strategies and points out that constructivist approaches can be further optimized to support conceptual understanding in complex scientific domains.
Eddie Murphy and the Dangers of Counterfactual Causal Thinking About Detecting Racial Discrimination
Authors: Kohler-Hausmann Issa
Published: February 2025

The model of discrimination animating some of the most common approaches to detecting discrimination in both law and social science-the counterfactual causal model-is wrong. In that model, racial discrimination is detected by measuring the "treatment effect of race," where the treatment is conceptualized as manipulating the raced status of otherwise identical units (e.g., a person, a neighborhood, a school). Most objections to talking about race as a cause in the counterfactual model have been raised in terms of manipulability. If we cannot manipulate a person's race at the moment of a police stop, traffic encounter, or prosecutorial charging decision, then it is impossible to detect if the person's race was the sole cause of an unfavorable outcome. But this debate has proceeded on the wrong terms. The counterfactual causal model of discrimination is not wrong because we can't work around the practical limits of manipulation, as evidenced by both Eddie Murphy's comic genius in the Saturday Night Live skit "White Like Me" and the entire genre of audit and correspondence studies. It is wrong because to fit the rigor of the counterfactual model of a clearly defined treatment on otherwise identical units, we must reduce race to only the signs of the category, meaning we must think race is skin color, or phenotype, or other ways we identify group status. And that is a concept mistake if one subscribes to a constructivist, as opposed to a biological or genetic, conception of race. The counterfactual causal model of discrimination is based on a flawed theory of what the category of race references, how it produces effects in the world, and what is meant when we say it is wrong to make decisions of import because of race. I argue that DISCRIMINATION is a thick ethical concept that at once describes and evaluates the actions to which it is applied, and therefore, we cannot detect actions as discriminatory by identifying a relation of counterfactual causality; we can do so only by reasoning about the action's distinctive wrongfulness by referencing what constitutes the very categories that are the objects of concern. An adequate theory of discrimination must rest upon (1) an account of the system of social meanings or practices that constitute the categories at issue and (2) a moral theory of what is fair and just in various state and private arenas given what the categories are.
High-frequency neurostimulation of the right inferior parietal cortex alters the sense of agency: results from tACS/tRNS and rTMS-EEG studies

Published: February 2025

Background: Sense of agency (SoA) is the subjective experience of causing and controlling one’s actions. Recent studies suggested that SoA can be influenced by external manipulation through neurostimulation methods, while others have linked it to gamma oscillations in the right inferior parietal lobule (IPL). Objective: This study aims to provide evidence for a causal role of the right IPL in SoA using multiple noninvasive brain stimulation methods (NIBS), electroencephalography (EEG), and a feedback manipulation task. Methods: In two experiments, we investigated the effect of gamma band (60 Hz) transcranial alternating current stimulation (tACS), transcranial random noise stimulation (tRNS), low-frequency (1 Hz) repetitive transcranial magnetic stimulation (rTMS), and high-frequency (10 Hz, 20 Hz) rTMS over the right IPL.Results: As anticipated, gamma band tACS and high-frequency rTMS had distinct effects on SoA. Gamma band tACS enhanced the detection of non-self agency, while high-frequency rTMS impaired this capacity and reduced the overall SoA. EEG spectral analysis confirmed the impact of stimulation on the right IPL and highlighted the role of beta band oscillations.Conclusion: Using the largest subject pool to date, our study provides causal evidence for the crucial role of the right IPL in processing SoA, particularly in detecting non-self agency arising from real-time sensorimotor mismatch comparison. Our findings suggest that external stimulation affects the comparator mechanism, rather than introducing prediction errors as previously proposed, and support the view that the right IPL is more closely associated with the implicit feeling of agency rather than with higher cognitive processes.
Domain-specific emotional effects of deepfakes on news-sharing behaviour
Authors: Ichikawa Kei , Chen Jiayu , Sasahara Kazutoshi
Published: February 2025

The rise of generative AI has raised societal concerns about the potential of synthetic media or deepfakes for misinformation. While previous research has established that negative emotions drive text-based misinformation sharing, their influence on deepfake dissemination remains poorly understood. Through two online experiments (N = 487; N = 479), we examined how emotional valence in deepfake images affects sharing intentions across political and entertainment news domains. Using GPT-3 and Stable Diffusion, we manipulated image emotional valence while maintaining consistent news contexts. Results revealed that negative images increased sharing intention only for political content, not entertainment content. Moreover, replacing negative images with less negative alternatives reduced sharing intention for political news, even among those initially inclined to share. These findings suggest domain-specific emotional dynamics in deepfake sharing and suggest novel content moderation strategies based on affective computing.
Language model BERT can estimate trait self-compassion from people's free texts with high accuracy
Authors: Okano Hirohito , Kawahara Daisuke , Nomura Michio
Published: February 2025

Self-compassion, which refers to compassion directed toward oneself, is associated with mental health and well-being. Traditionally, self-compassion has been measured and quantified using questionnaire scales such as the Self-Compassion Scale (SCS) and Compassionate Engagement and Action Scales (CEAS). In recent years, interest in quantifying psychology using text described by people and state-of-the-art natural language processing methods, such as BERT, has increased. In this study, short open-ended free texts were collected from participants asking about their thoughts (general thoughts and those about themselves and others) and behaviors in three challenging situations. Then, a regression model was developed to predict the self-compassion scores (i.e., SCS and CEAS) from free texts with BERT. The self-compassion scores quantified by free texts and BERT highly correlated with the SCS score and certain criterion-related validity. Furthermore, the results suggest that thoughts, behaviors, and levels of self-compassion differ across situations and that the SCS score is related to both cognition (thoughts) and behaviors. The method of psychological quantification using free text may be less prone to priming or bias than measurement using questionnaires. Thus, future studies are encouraged to apply this natural-language-based approach to more diverse samples and other psychological constructs.

Self-compassion, which refers to compassion directed toward oneself, is associated with mental health and well-being. Traditionally, self-compassion has been measured and quantified using questionnaire scales such as the Self-Compassion Scale (SCS) and Compassionate Engagement and Action Scales (CEAS). In recent years, interest in quantifying psychology using text described by people and state-of-the-art natural language processing methods, such as BERT, has increased. In this study, short open-ended free texts were collected from participants asking about their thoughts (general thoughts and those about themselves and others) and behaviors in three challenging situations. Then, a regression model was developed to predict the self-compassion scores (i.e., SCS and CEAS) from free texts with BERT. The self-compassion scores quantified by free texts and BERT highly correlated with the SCS score and certain criterion-related validity. Furthermore, the results suggest that thoughts, behaviors, and levels of self-compassion differ across situations and that the SCS score is related to both cognition (thoughts) and behaviors. The method of psychological quantification using free text may be less prone to priming or bias than measurement using questionnaires. Thus, future studies are encouraged to apply this natural-language-based approach to more diverse samples and other psychological constructs.
The embodied roots of disgust: exploring the link between disgust sensitivity, interoception and political ideology

Where does political ideology come from? Early research in political neuroscience has linked stronger physiological responses to threat and disgust with conservatism, implying a neurobiological basis of ideology, beyond societal factors. However, recent replication failures challenge the idea of a direct connection between physiological reactions and political attitudes. Given the role of interoception in body-awareness and emotional regulation, we investigated whether the relationship between disgust and political ideology is moderated by interoceptive sensibility (i.e., one’s ability to be attuned to their internal bodily states). Using survey data from 632 U.S. participants (321 Democrats, 311 Republicans), we show that when people have higher interoceptive sensibility, their political ideology is not driven by their disgust sensitivity. It is only when interoceptive sensibility is low that disgust sensitivity plays a significant role in political ideology: higher disgust sensitivity increases the likelihood of identifying as Republican, while lower disgust increases the likelihood of being Democrat. We propose that individuals with higher interoceptive sensibility rely more on physiological signals to process emotions like disgust. As a result, their ideological differences are less shaped by internalized cultural beliefs about what is disgusting and instead reflect their actual physiological experience. In contrast, those with lower interoception are more susceptible to socially constructed associations, relying more on ‘social priors’ to interpret their physiological states. This research highlights the importance of interoception in political cognition, offering a novel perspective on the psychophysiological underpinnings of political ideology, paving the way for replicable and causal studies.
Measuring Intellectual Curiosity Across Cultures: Validity and Comparability of a New Scale in Six Languages

Intellectual curiosity—the tendency to seek out and engage in opportunities for effortful cognitive activity—is a crucial construct in educational research and beyond. Measures of intellectual curiosity vary widely in psychometric quality, and few measures have demonstrated validity and comparability of scores across multiple languages. We analyzed a novel, six-item intellectual curiosity scale (ICS) originally developed for cross-national comparisons in the context of the OECD’s Programme for the International Assessment of Adults Competencies (PIAAC). Samples from six countries representing six national languages (US, Germany, France, Spain, Poland, and Japan; total N = 5,557) revealed that the ICS possesses very good psychometric properties. The scale is essentially unidimensional and showed excellent reliability estimates. On top of factorial validity, the scale demonstrated strict measurement invariance across demographic segments (gender, age groups, educational strata) and at least partial scalar invariance across countries. As per its convergent and divergent associations with a broad range of constructs (e.g., Open-Mindedness and other Big Five traits, Perseverance, Sensation Seeking, and Job Orientations/Vocational Interests), it also showed convincing construct validity. We recommend the ICS for assessing intellectual curiosity, especially in cross-cultural research applications, yet we also point out future research areas.
Probiotics Impact on Cognitive Ability and Emotionsin Adolescents: A Brain-Gut Axis Study

The Gut-Brain Axis (GBA) is a bidirectional communication system between the central nervous system (CNS) and the enteric nervous system (ENS), with recent research highlighting the key role of gut microbiota in regulating GBA functions. This study aims to explore the effects of probiotics on adolescents’ cognitive abilities, memory, and emotions. A double-blind, randomized controlled trial was conducted, involving 15 healthy adolescents aged 15 to 18, randomly assigned to a treatment group receiving probiotics and a control group receiving a placebo. The study included baseline assessments, a four-week intervention, and post-intervention evaluations using the Positive and Negative Affect Schedule (PANAS) and the Montreal Cognitive Assessment (MoCA). The MoCA scores showed significant cognitive improvement in the treatment group, while the control group’s improvement was not significant. PANAS scores indicated a significant increase in positive emotions in the treatment group, with no notable changes in the control group. The results support the hypothesis that probiotics positively impact adolescent cognitive function and emotional state by regulating gut microbiota. Despite the limited sample size, this study provides preliminary scientific evidence for the potential therapeutic application of probiotics in adolescents. Future studies should include larger sample sizes and longer intervention periods to further validate these findings.
Temporal dynamics of full-body ownership and vicarious touch sensations as inferred from embodying a virtual avatar

Feeling a tactile sensation when observing a touch on an artificial body (Vicarious Touch, VT) and the illusion of full-body ownership (Full-body Ownership Illusion, FBOI) can be effectively induced using Virtual Reality (VR). However, the onset timing of these phenomena, particularly under visual-only stimulation, remains poorly understood. While prior research has focused on body-part ownership under visuotactile conditions, the temporal dynamics of VT in a full-body context remain underexplored.This study investigated FBOI and VT in 34 healthy participants observing a virtual body from either a first-person (1PP) or third-person (3PP) perspective. Illusory experiences were categorized into different outcomes, and participants provided subjective ratings of onset timing and intensity. These were analyzed alongside physiological measures (respiratory rate, heart rate variability, and skin conductance) and psychological traits (empathy and attachment) to explore factors modulating these experiences.Results showed that 1PP significantly accelerated and intensified both FBOI and VT, highlighting the pivotal role of perspective in sensory integration. Conversely, 3PP was linked to a higher prevalence of No Illusion outcomes and weaker illusions, reflecting difficulties in aligning sensory cues. Respiratory rate emerged as a marker of VT experiences, while empathy predicted faster and more intense VT, indicating greater sensitivity in emotionally attuned individuals.These findings provide insights into the temporal dynamics of VT and FBOI, with implications for VR-based therapeutic applications targeting sensory integration and body representation.
