Reflexivity and the ability to predict activities as the basis for future professional personality formation

In the context of dynamic transformations in all spheres of activity, the particular importance of professional’s abilities for reflexive and prognostic activity in adapting to new challenges is obvious. Future professionals need the ability to solve non-standard tasks, cope with emerging problems, control their own actions, readiness for objective assessment of work results, self-education and professional development. The aim of the research is to define the essence and content of the reflective and prognostic abilities of an individual, their significance in professional activity, as well as to identify the level of development of these qualities among university students in psychological-pedagogical and technical fields of study, and to outline the conditions for their productive development. The authors carried out a theoretical analysis of the definitions of «reflexivity» and «forecasting», reflected in numerous psychological and pedagogical studies of interdisciplinary focus by scientists from different countries. The relationship between reflexive and prognostic abilities with self-regulation of behavior and activity of an individual, their adaptation and professionalization were revealed. Diagnostics were conducted to determine the level of reflexivity (suggested by A.V. Karpov, V.V. Ponomareva) and the prediction ability (suggested by L.A. Regush) among first-year students of the psychological and pedagogical fields of study at Peter the Great St. Petersburg Polytechnic University and the technical field at Samara State Technical University. The results of psychodiagnostics of reflexive and predictive abilities of students are presented and indicate an insufficient level of predisposition to retrospective, situational, prospective reflection and forecasting. However, the implementation of an integrated approach in classroom and extracurricular training, the use of intensive pedagogical technologies (practice-oriented, heuristic, informational) in the educational process, the problem solving techniques and test material developed on the basis of the matrix model of cognitive activity during intermediate monitoring showed positive dynamics in the increase of the level of development of reflexive and predictive student abilities.

Analysis of the Applications of Algorithm and Automatic Pathfinding

Abstract. The current development of autonomous driving technology is very hot, which involves two fundamental aspects: one is the operating system as the foundation, and the other is the algorithm application. The theme of this review is to study the related algorithmic technologies and combine them with one of the key functions of autonomous driving: autonomous routing. The review discusses the application direction and environment of this function, and involves the use of algorithms in the backend. Autonomous routing is a key concept in multiple technical fields and plays an important role in helping entities effectively navigate complex environments. This review centers on the concept of autonomous routing and focuses on its application direction, usage environment, and supporting algorithms. The core research question is autonomous routing and its working principle. The review analyzes the main application scenarios of autonomous routing, such as autonomous driving and game development, and explores the algorithms commonly used in these scenarios. By conducting a comprehensive analysis of the main usage environments and algorithm structures, the review provides insights into the current state of autonomous routing technology. The research findings show that autonomous routing technology has been deeply embedded in multiple industries and is continuously expanding as the demand for technology grows. Furthermore, the review explores the potential future development of autonomous routing, anticipating that it will further develop in responding to various new challenges and opportunities.

On physical analysis of topological indices and entropy measures for porphyrazine structure using logarithmic regression model.

The porphyrazine structure, known for its high chemical and thermal stability, has become a significant focus in materials science, chemical reactivity, functionalization, and drug design. By utilizing the new Zagreb-type indices to analyze the chemical structure of porphyrazine, we can gather more information about their bonding and connecting patterns. This enables us to construct an entropy measure that helps evaluate the stability of the material and predict its behavior in different scenarios. Furthermore, establishing correlations between these indices and entropy using logarithmic regression models allows for a deeper understanding of complex properties of porphyrazine. This, in turn, opens up new possibilities for the compound's potential applications across various scientific and technical fields. In our work, we have used the M-polynomial to derive molecular descriptors for degree-based topological indices and determine the entropy of the porphyrazine structure based on these descriptors.

Multi-Metal Additive Manufacturing by Extrusion-Based 3D Printing for Structural Applications: A Review

Additive manufacturing (AM) is a rapidly developing technical field that is becoming an irreplaceable tool to fabricate unique complex-shaped parts in aerospace, the automotive industry, medicine, and so on. One of the most promising directions for AM application is the design and production of multi-material components with different types of chemical, structural, and architectural gradients that also promote a breakthrough in bio-inspired approaches. At the moment there are a lot of different AM techniques involving various types of materials. This paper represents a review of extrusion-based AM techniques using metal-polymer composites for structural metal parts fabrication. These methods are significantly cheaper than powder bed fusion (PBF) and directed energy deposition (DED) techniques, though have a lower degree of part detail. Thus, they can be used for low-scale production of the parts that are not rentable to produce with PBF and DED. Multi-material structures application in machinery, main aspects of feedstock preparation, the subsequent steps of extrusion-based 3D printing, and the following treatment for manufacturing single-metallic and multi-metallic parts are considered. Main challenges and recommendations are also discussed. Multi-metallic extrusion-based 3D printing is just a nascent trend requiring further wide investigation, though even now it shows pretty interesting results.

The multidimensional coagulation and collisional breakage equation with unbounded kernel

Many scientific and technical fields have benefited from the understanding of the Coagulation and Collisional Breakage Equation (CCBE). In one-dimensional CCBE, only one property of the particle (like size or mass of the particle) is considered. However, there are other factors (like including volume, enthalpy, porosity, mole number, binder content, and more) that affect how particle ensembles behave. Therefore the study of multidimensional CCBE is more accurate. For the multi-dimensional (CCBE), we denote the property characteristics vector as x → = ( x 1 , x 2 , … , x d ) ∈ R + d . In this research work, the existence of a continuous solution is investigated where collision rate satisfies C ( x → , y → ) ≤ c ∏ i = 1 d ( 1 + x i ) ν ( 1 + y i ) ν , where c>0 is a constant, 0 ≤ ν ≤ θ and the coagulation kernel satisfies the following, K ( x → , y → ) ≤ k ∏ i = 1 d ( 1 + x i ) α ( 1 + y i ) α , where k is a positive constant, 0 ≤ α ≤ θ and 0 < θ ≤ 1 . Additionally, the uniqueness of the solution is shown. To prove the result, we have defined a new norm and examined the equicontinuity with respect to time and the property characteristics vector and Arzelà–Ascoli theorem is used.

Field of study, political attitudes, and support for the radical right in Sweden and Europe

This study uses three different surveys to investigate the links between various educational fields, radical right support, and political opinions. Logit regressions and KHB mediation analysis of 41,770 observations from the Swedish SOM survey (2011–2019) reveal that graduates from technical and agricultural fields are approximately twice as likely to support the radical right as graduates from sociocultural fields. Fields such as natural sciences, business, and health demonstrate medium to medium-high support. These differences are partially mediated by horizontal, but not vertical, labor market allocation. Replication using the European Social Survey (ESS) indicates that these patterns are generalizable to Western, but not Eastern, Europe. Additional analyses show that radical right support and refugee intake skepticism decrease with years spent in sociocultural, but not technical, fields in upper-secondary school. Moreover, panel data from the Swedish Level of Living Survey (LNU) show that progressive attitude shifts occur predominantly following education in sociocultural fields.

A Three-Block Inexact Heterogeneous Alternating Direction Method of Multipliers for Elliptic PDE-Constrained Optimization Problems with a Control Gradient Penalty Term

Optimization problems with PDE constraints are widely used in engineering and technical fields. In some practical applications, it is necessary to smooth the control variables and suppress their large fluctuations, especially at the boundary. Therefore, we propose an elliptic PDE-constrained optimization model with a control gradient penalty term. However, introducing this penalty term increases the complexity and difficulty of the problems. To solve the problems numerically, we adopt the strategy of “First discretize, then optimize”. First, the finite element method is employed to discretize the optimization problems. Then, a heterogeneous strategy is introduced to formulate the augmented Lagrangian function for the subproblems. Subsequently, we propose a three-block inexact heterogeneous alternating direction method of multipliers (three-block ihADMM). Theoretically, we provide a global convergence analysis of the three-block ihADMM algorithm and discuss the iteration complexity results. Numerical results are provided to demonstrate the efficiency of the proposed algorithm.

Gambling Disorder among Croatian University Students

Abstract Background Gambling has become a routine form of entertainment for many young people studying in universities. This study aimed to investigate the prevalence and characteristics of gambling disorder among Croatian university students. Methods A cross-sectional study using an anonymous self-administered questionnaire with sociodemographic and socioeconomic questions along with the Croatian version of the South Oaks Gambling Screen questionnaire (SOGS-CRO) was conducted in a representative sample of Croatian university students from Osijek, Eastern Croatia during January, and February 2020. Results A total of 844 students participated in the study, 45.6% males and 54.4% females, with a median age of 19.00 years (interquartile range 19.00-23.00 years). Gambling activities were performed by 66.2% of the students, most commonly lotteries, sports bets, and bingo. The final scores of the SOGS-CRO suggested that 21.1% of students may have a gambling disorder, with 16.4% being “probable pathological gamblers” and 4.7% being “problem gamblers”. Playing cards for money, animal bets, stocks bets, slot machines bets, pull-tabs, and other gambling activities such as online or videogames or mobile games present a higher risk of gambling disorder (p &amp;lt; 0.001, p &amp;lt; 0.001, p &amp;lt; 0.001, p &amp;lt; 0.001, p &amp;lt; 0.001, p &amp;lt; 0.001, respectively). Being male, repeating the year of study, being a student in interdisciplinary or technical field of study, and having a mother with gambling disorder (p &amp;lt; 0.001, p = 0.029, p &amp;lt; 0.001, p &amp;lt; 0.001, respectively) were the revealed contributing factors to the development of gambling disorder in study participants. Conclusions The study points to the fact that gambling disorder is quite a prevalent public health issue in the Croatian university student population. Specific public health preventive programs need to be designed and implemented in the study population to successfully prevent the development of investigated behavioral addiction. Key messages • Public health interventions directed toward the prevention of gambling must involve younger population subgroups, such as university students. • When designing the preventive programs for the successful prevention of gambling within the university student population selected sociodemographic variables should be considered.

Thus, the purpose of this study was to determine the physical characteristics of the land in the research area. The method used is the survey and mapping method in data collection and descriptive analysis. The results of the study obtained are the physical characteristics of the land of the Godean Jogja Hills housing area, there are several criteria that are appropriate and inappropriate. The criteria that are not appropriate are slope gradient, area of green open space, drainage infrastructure capacity, not located in a disaster-prone area (landslides, floods, erosion, and abrasion), not located in an agricultural/buffer cultivation area, distance to educational facilities, health facilities and trade and commerce facilities and the appropriate criteria are the area for building houses, water availability, not located in the border area of rivers/coasts/reservoirs/lakes/springs/irrigation channels/railways and safe flight areas, not located in protected areas, avoiding technical irrigation rice fields, wastewater disposal systems and garbage disposal systems

Sustainable development awareness and integration in higher education: a comparative analysis of universities in Central Asia, South Caucasus and the EU

Education for sustainable development in universities is shaping the agenda in this area, demanding continuous improvement in quality. There is a trend towards integrating sustainability issues and the implementation of sustainable development goals into higher education. Universities responsible for educating SD professionals must teach knowledge and develop skills in line with the SDGs. However, there is insufficient attention to this in educational programs; more often it is implemented through disparate initiatives. The article presents research conducted in universities in the countries of Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan), South Caucasus (Georgia, Armenia) and the European Union (Italy, Bulgaria, Poland). The awareness of students and teachers about the SDGs, the problems of implementing SD were assessed, and ways to solve these problems were analyzed. Countries were divided into clusters for comparative analysis. The results show that students generally have limited knowledge about the global sustainable development goals, while teachers have a higher level of awareness. The article examines the contribution of education to raising students' awareness in the countries studied and their attitudes towards integrating sustainability into the curriculum. The questionnaire showed that the educational intervention significantly influences students’ intention to engage in sustainability. Overall, students demonstrate positive attitudes towards incorporating sustainability issues into their education. The results of a study conducted in higher education institutions in Central Asia, South Caucasus and the European Union showed that students are generally unaware of the sustainable development goals, their information received through the Internet, media and university studies is insignificant, while teachers are better informed. Students and teachers expressed the greatest concern about environmental, social and economic problems. At the same time, students of engineering, technical and medical fields are more informed about the SDGs compared to pedagogical and socio-humanitarian fields. To increase awareness, universities are encouraged to integrate sustainability education into various disciplines, conduct seminars, round tables, promote student participation in projects and research, and promote international cooperation and knowledge sharing.

Leadership in Technical Fields Through a Gender Lens

Although women have fought for labor rights for many years, they continue to be underrepresented at almost all levels of decision-making. The present study aims to provide insights into female leadership in technical fields both in the EU and in Russia. The article examines the principal leadership aspects of women’s status and career experiences. To identify the ingredients of successful leadership, the Multifactor Leadership Questionnaire and interviews were administrated to a sample of 200 mining students and 40 senior executives. The research data were processed by means of correlative, regressive, and autocorrelation analyses. To track the consistency of the identified leadership factors, female heads of enterprise divisions and university departments shared their views on career progress. The Mann–Whitney U test was employed to analyze the leadership factors. Studies indicate that the more senior the position is, the fewer women there are in leadership roles. Women’s progress in technical careers is hindered both by their own uncertainty and judgments made by others about their abilities. To rectify this situation, practices for encouraging young women to pursue technical careers are recommended along with approaches for maintaining them within the career structure. The research findings also indicate a positive emerging global trend towards increased gender diversity in technical fields.

Assessment of the mechanical and functional properties of nitinol alloys fabricated by laser powder bed fusion: Effect of strain rates

Laser Powder Bed Fusion-fabricated (LPBFed) nitinol shape memory alloys (SMAs), which undergo solid-solid phase transitions between austenite and martensite, are increasingly utilized in various technical fields and are subjected to a wide range of strain rates during service. This study pioneers the investigation of a comprehensive range of strain rates (3.16 × 10−6-10°/s), encompassing the strain rates used in quasi-static tensile tests reported in the existing literature, to understand their effects on the deformation mechanisms of LPBFed nitinol SMAs. Utilizing multi-scale characterization, including macroscopic mechanical evaluation, mesoscale analysis of deformation surfaces, and microscale examination of microstructure, we reveal distinct deformation behaviors at different strain rates. At lower strain rates, the mechanical behavior exhibits little sensitivity to changes in the strain rates, with stress-induced martensite transformation or martensite detwinning and variant reorientation being the primary deformation mechanisms. However, at higher strain rates, we observe significant variability in mechanical response, dominated by dislocation-induced slip and reduced occurrence of stress-induced martensitic transformation. This study provides the first comprehensive database for the engineering applications of LPBFed Nitinol SMAs and offers critical insights into optimizing mechanical and functional assessments for these advanced materials.
