Electroencephalography Correlates of Well-Being Using a Low-Cost Wearable System

Electroencephalography (EEG) alpha asymmetry is thought to reflect crucial brain processes underlying executive control, motivation, and affect. It has been widely used in psychopathology and, more recently, in novel neuromodulation studies. However, inconsistencies remain in the field due to the lack of consensus in methodological approaches employed and the recurrent use of small samples. Wearable technologies ease the collection of large and diversified EEG datasets that better reflect the general population, allow longitudinal monitoring of individuals, and facilitate real-world experience sampling. We tested the feasibility of using a low-cost wearable headset to collect a relatively large EEG database (N = 230, 22–80 years old, 64.3% female), and an open-source automatic method to preprocess it. We then examined associations between well-being levels and the alpha center of gravity (CoG) as well as trait EEG asymmetries, in the frontal and temporoparietal (TP) areas. Robust linear regression models did not reveal an association between well-being and alpha (8–13 Hz) asymmetry in the frontal regions, nor with the CoG. However, well-being was associated with alpha asymmetry in the TP areas (i.e., corresponding to relatively less left than right TP cortical activity as well-being levels increased). This effect was driven by oscillatory activity in lower alpha frequencies (8–10.5 Hz), reinforcing the importance of dissociating sub-components of the alpha band when investigating alpha asymmetries. Age was correlated with both well-being and alpha asymmetry scores, but gender was not. Finally, EEG asymmetries in the other frequency bands were not associated with well-being, supporting the specific role of alpha asymmetries with the brain mechanisms underlying well-being levels. Interpretations, limitations, and recommendations for future studies are discussed. This paper presents novel methodological, experimental, and theoretical findings that help advance human neurophysiological monitoring techniques using wearable neurotechnologies and increase the feasibility of their implementation into real-world applications.

Factors Affecting Financial Behaviors:

This study was conducted to determine the effect of financial knowledge, financial attitude, locus of control, risk tolerance, motivation, and mental accounting on financial behavior. The population was 168 students majoring in International Business Management at Universitas Ciputra Surabaya. The characteristics of the respondents are students who are in the 6th semester and above at the time of taking the sampling with purposive sampling method. The data obtained were analyzed using Partial Least Square (PLS). The result shows that the factors of financial knowledge, locus of control, motivation, have no effect on financial behavior. While the factors of financial attitude, risk tolerance, and mental accounting have an effect on financial behavior.

INVESTIGATION OF SOME PSYCHOLOGICAL CHARACTERISTICS OF ATHLETES DEALING WITH WATER SPORTS

Background: It is known that many factors can cause pressure for the athlete in sports performed on water rather than any outdoor sports. In this context, it is important to train athletes' cognitive abilities and skills with a strong mindset and to increase their awareness of their psychological characteristics. Aim: The aim of the study is to examine the psychological characteristics of athletes engaged in water sports regarding locus of control, motivation and achievement orientation and to determine possible relationships between them. Appropriate sampling, one of the non-probabilistic sampling methods, was used in determining the participants, and the study was carried out with a correlational survey model. A total of 147 licensed athletes (34 females and 113 males), including 48 windsurfers, 36 individual sails, 37 sets of sails, 26 kitesurf, participated in the study. Material and methods: The participants were administered the “Revised Locus of Control Scale”, “Sports Motivation Scale II” and “2x2 Achievement Orientation Scale”. Descriptive statistics, independent samples t-test, one-way ANOVA and Pearson correlation analysis were used in the analysis of the data. Results: According to the analysis results, it was determined that there are statistically significant differences between national and non-national athletes in all sub-dimensions of the achievement orientation scale and that all athletes have a positive orientation towards learning. The average scores of the performance-approach sub-dimension of athletes aged 20 and under and the amotivated sub-dimension of individuals with sports age 9 and over were found to be significantly higher. In addition, a moderately significant positive correlation was found between performance-avoidance achievement orientation and the integrated regulation motivation dimension, and between intrinsic regulation and learning-approach orientation. Conclusion: As a result, it is thought that individuals dealing with water sports can develop different strategies according to their psychological characteristics on the way to success and the findings will contribute to the field of sports psychology.

В статье рассматриваются вопросы и проблемы создания цифровых двойников (ЦД) корпусов судов. Целью является разработка соответствующих методик. Отмечается, что классификационные и нормативные требования к ЦД корпуса судна в отечественной практике пока отсутствуют. Определяется цель и основные задачи ЦД, их роль в управлении жизненным циклом (ЖЦ) судна. Отмечается, что применение ЦД корпуса судна позволит анализировать текущее состояние корпуса судна, а в перспективе повлиять на решение проблем проектирования и эксплуатации судов, нормирования их безопасности. Анализируются противоречия, возникающие при внедрении технологии ЦД в существующую систему нормирования и проектирования судов. Исходя из этого, сформулированы принципы разработки методик создания ЦД: структуризация и модульность; иерархия моделей и подмоделирование; управление с обратной связью; стимул к совершенствованию правил классификационных обществ. Предложена структура методик разработки ЦД корпуса судна. Определены основные этапы разработки ЦД. Рассматривается пример разработки ЦД пассажирского высокоскоростного катамарана из композиционных материалов на основе среды разработки ANSYS Workbench на этапе технического проекта судна. Предложена структура ЦД на этапе рабочего проектирования и эксплуатации корпуса судна. The article discusses the issues and problems of creating digital twins (DT) of ship hulls. The aim is to develop appropriate methodic. It is noted that there are no classification and regulatory requirements for the DT of a ship's hull in domestic practice so far. The purpose and main tasks of the DT are determined, their role in the life cycle management of the ship. It is noted that the use of the ship's hull DT will make it possible to influence the solution of modern problems of the design and operation of ships, the regulation of their safety. The contradictions arising from the introduction of the DT technology into the existing system of regulation and design of ships are analyzed. Proceeding from this, the principles for developing methods for creating a DT were formulated: structuring and modularity; model hierarchy and sub-modeling; feedback control; motivation to improve rules of classification societies. The structure of methods for the development of the ship's hull DT is proposed. The main stages of DT development are determined. An example of the development of a DT of the passenger high-speed catamaran made of composite materials based on the ANSYS Workbench development environment at the stage of a ship's technical design is considered. The structure of DT models at the stage of detailed design and operation of the ship's hull is proposed.

Cutting, Driving, Digging, and Harvesting: Re-masculinizing the Working-Class Heroic

Television portrayals of working-class males in blue-collar jobs have in the past proven unflattering at best, demeaning at worst. But a new breed of unscripted TV shows articulates a fundamentally different narrative about the unsung heroism of working-class men. This article explores the narratives and images associated with the re-masculinization of blue-collared working-class males as real men in contrast to conventional working-class misrepresentations as persons lacking self control, motivation and commitment. This genre of “macho” male programs constitutes a key ideological tool by which “hegemonic” narratives of conventional masculinity are internalized through the “pleasures of the media.” The authors conclude that, despite the recent valorization of blue-collar values, contributions, and identities, representational distortions and content omissions persist in portraying working class realities.

Disease History and Life History Predict Behavioral Control of the COVID-19 Pandemic

It is puzzling why countries do not all implement stringent behavioral control measures to prevent the spread of COVID-19 even though preventive behaviors have been proven to be the only effective means to stop the pandemic. We provide a novel evolutionary life history explanation whereby pathogenic and parasitic prevalence represents intrinsic rather than extrinsic mortality risk that drives slower life history strategies and the related disease control motivation in all animals but especially humans. Our theory was tested and supported based on publicly available data involving over 150 countries. Countries having a higher historical prevalence of infectious diseases are found to adopt slower life history strategies that are related to prompter COVID-19 containment actions by the government and greater compliance by the population. Findings could afford governments novel insight into the design of more effective COVID-19 strategies that are based on enhancing a sense of control, vigilance, and compliance in the general population.
