Self-leadership as the ability for self-management in relation to academic procrastination of engineering students

Introduction. In the modern educational environment, attention is increasingly focused on the development of students’ personalities. The ability to self-organize, self-discipline and self-motivation becomes a necessary skill both for achieving educational goals and for successful integration into the professional environment of a future specialist. The purpose of the study is to study the influence of self-leadership, self-management and self-esteem on the level of academic procrastination of engineering students. Materials and methods. The sample is represented by 138 students of the St. Petersburg State University of Architecture and Civil Engineering, the average age was 20 years. The following methods were used: «Questionnaire to determine the level of self-leadership», adapted by Kim E-sung, «Scale for assessing academic procrastination», adapted by M.V. Zverev, questionnaire «Ability to self-government» N.M. Peysakhova, test «Determination of the level of self-esteem» S.V. Kovaleva. Results. The self-leadership and self-management skills of engineering students are at the «above average» level, there is also an average level of procrastination, and a low level of self-esteem was found. Students' academic procrastination decreases with a high level of goal-setting ability (r=-0,19; p≤0,05), introspection (r=-0,19; p≤0,05), self-control (r=-0,20; p≤0,05). Procrastination increases when using the strategies of «self-reward» (r=0,18, p≤0,05) and «visualization of one’s own success» (r=0,19, p≤0,05), as well as with high self-esteem (r=0,23; p≤0,001). Girls are more likely to procrastinate, care about the quality of work, and reward themselves after achieving results than boys. The most significant contribution to the academic procrastination of engineering students is made by goal setting (B = -0,36) and «visualization of one’s own success» (B = 0,40). Conclusion. Academic procrastination is one of the common problems in education. Self-leadership as the ability for self-management has a significant impact on procrastination, reducing it. Further research into the phenomenon of self-leadership may contribute to the development of programs for developing selfmanagement skills, which will improve learning outcomes.

Investigating the Ability in Constructing Scientific Explanations of Thai Grade 10 Students: Insights from Learning Achievement, Attitude, and School Size

The ability to construct scientific explanations is a vital goal of learning science at all levels. Students from different backgrounds are likely to have this ability differently. This research aimed to assess Thai grade 10 students’ ability to construct scientific explanations, examine differences based on learning achievement, attitude toward science, and school size, and find correlations among these variables. The study included 231 students from Phetchaburi province, Thailand, with 77.5% showing moderate ability levels. The research identified significant differences in students’ ability levels based on their learning achievement, attitude toward science, and school size. The levels of students’ ability correlated with their learning achievement, attitude toward science, and school size. In addition, students with high learning achievement, and positive attitudes, and who attended larger schools tended to have higher ability levels. However, there was no significant relationship between the levels of students’ attitudes toward science and school size. These findings highlight the importance of considering individual differences and backgrounds when teaching science, particularly in terms of learning achievement, attitude toward science, and school size.

Evaluation of time to sputum smear conversion and its association with treatment outcomes among drug-resistant tuberculosis patients: a retrospective record-reviewing study.

Background: This study examined the time to sputum smear and culture conversion and determinants of conversion, as well as variables associated with treatment outcomes among drug-resistant pulmonary tuberculosis (DR-PTB) cases. Methods: The electronic database and written medical records of patients were utilized to assess the sociodemographic, clinical, microbiological, and treatment characteristics and outcomes of study participants. Results: Among 736 patients with pulmonary tuberculosis (PTB), the mean age was 36.5 ± 16.5years, with males comprising 53.4% and a mean weight of 47.76 ± 11.97kg. The median time period for sputum smear conversion and sputum culture conversion was a month. The first-month culture conversion (p < 0.001, aOR = 5.817, and 95% CI = 3.703-9.138) was the determinant of sputum smear conversion and receiver operating curve analysis with AUC = 0.881, 95% CI = 0.855-0.907, and p < 0.001, which showed a high level of predictive ability for the regression model for the initial sputum smear conversion. However, the first-month sputum conversion (p < 0.001, aOR = 7.446, and 95% CI = 4.869-11.388) was attributed to sputum culture conversion, and the model has shown excellent predictive ability for regression with ROC curve analysis demonstrating AUC = 0.862, 95% CI = 0.835-0.889, and p < 0.001. A total of 63.2% of patients showed favorable treatment outcomes, with 63.1% of cases achieving treatment-cured status. The previous use of SLD, history of smoking, duration of illness ≤ 1 year, extensively drug-resistant tuberculosis, and first-month sputum conversion were the variables attributed to favorable treatment outcomes observed in drug-resistant pulmonary tuberculosis cases. ROC curve analysis with AUC = 0.902, 95% CI = 0.877-0.927, and p < 0.001) has shown outstanding ability for regression model prediction for the variables influencing treatment outcomes. Conclusions: Within 2months of treatment, most patients had converted their sputum cultures and sputum smears. The determinants of early sputum smear and sputum culture conversion, as well as favorable treatment outcomes, were identified. These factors should be considered during the design and implementation of effective strategies for drug-resistant tuberculosis control programs.

Can metacognition determine employee performance in the context of virtual workspace? An empirical investigation

PurposeThe pandemic has necessitated employees to work virtually due to mandatory work-from-home setup. Since every employee is not comfortable working online owing to their individual differences which impact performance, thus, it is essential to identify individual characteristics governing performance. As per conventional theories, cognition and metacognition have a significant impact on employee performance, and the key to performance in a collaborative online environment also is metacognition. However, this has been scarcely explored in the context of virtual workspace. This study, therefore, empirically investigates the influence of metacognition and its sub-domains on employees' virtual performance given the challenges they face in a virtual work environment.Design/methodology/approachThe cross-sectional study used a purposive sampling technique for data collection. Data collected from 534 professionals with high and low levels of metacognitive ability is analysed using univariate analysis to ascertain whether metacognitive ability helps employees deal with challenges associated with virtual work environments and perform better.FindingsResults confirm a significant relationship between the level of metacognitive ability and virtual performance. Further, the findings also confirm the interaction effect of the level of metacognitive ability and challenge of maintaining work and non-work boundaries and the need for the physical presence of team member/s in predicting virtual performance.Originality/valueThis study is the first empirical attempt to examine the linkage between metacognitive ability and performance among professionals in the context of post-pandemic virtual work environment and challenges.

A STUDY ON THE FACTORS INFLUENCING THE TURNOVER BEHAVIOR OF NEW GENERATION EMPLOYEES IN INSURANCE COMPANIES

Along with the rapid development of the insurance industry, the requirements for insurance practitioners are also increasing. From traditional insurance businesses to digital businesses, employees are required to maintain a high level of learning and work abilities in order to face the complex and ever-changing market environment. The advantages of the new generation of employees are their strong work ability and high learning ability, but the disadvantages are that they have distinct personalities and do not attach enough importance to the authority of their leaders. They like to act according to their own style when doing things. Using the new generation of employees properly can benefit the organization, but improper use can cause harm. With the increasing proportion of new-generation employees in the organization, how to effectively manage them, reduce their turnover rate, and ensure the stable development of the talent team is an issue that organizational management should pay attention to. Empirical analysis shows that three influencing factors, namely organizational fairness, promotion channels based on the term target responsibility system, and a highly flexible salary structure, can reduce the probability of turnover behavior among the new generation of employees in insurance companies. The highly flexible salary structure has the greatest impact on the turnover behavior of new generation employees in insurance companies, proving that addressing the material needs of new generation employees can stabilize the talent pool of new generation employees.

The development of ethnoeducational competence of the future teacher

Relevance. The Republic of Kazakhstan faces a challenging task in developing a competitive and competent professional workforce with high intellectual potential and positive personal qualities. Purpose. The purpose of the presented research is to study and analyse the development of the ethnoeducational competence of the future teacher. Methodology. The methods of information analysis and synthesis, the comparative method, as well as the method of induction and deduction, were used in this study. At the final stage of the study, the method of analysing scientific literature relevant to the subject was used. Results. In the process of analysing literary sources, it was determined that, according to researchers, the ethnoeducational competence of a teacher should include: methods of implementing various models of teaching conventional pedagogical literature focused on the characteristics of different typological groups of students, the most typical ways of solving ethnoeducational problems presented in the content of school subjects and their use for the development of schoolchildren, as well as methods of awakening and developing students' cognitive interest in ethnoeducational content. It was determined that some researchers interpret ethnoeducational competence as a set of certain personality qualities with a high level of ethnoeducational preparedness and ability for creative activity, in which the professional and personal qualities of a teacher are maximally manifested. Conclusions. Ethnoeducational competence involves engaging diverse students, addressing ethnoeducational challenges, and fostering student interest in related content. It merges professional skills with personal attributes necessary for effective teaching. The practical value of this research lies in its application to the development of future teachers' ethnoeducational competence, serving as a foundation for further pedagogical studies and benefiting teachers, students, and pedagogy researchers.

RESEARCH ON THE IMPACT OF CORPORATE CULTURE ON THE TURNOVER OF KNOWLEDGE EMPLOYEES - TAKING WORK HAPPINESS AS A FACTOR

In new energy vehicle manufacturing enterprises, the proportion of knowledge-based employees is the highest because the software and hardware design belong to the high-end manufacturing scope, which requires high levels of knowledge and learning ability from employees. The majority of knowledge-based employees have completed their higher education, allowing them to immediately apply their acquired professional knowledge to their work positions. Moreover, knowledge-based employees have relatively high innovation abilities. Corporate culture serves as the foundation for a company's overall organizational atmosphere. If a knowledge-based employee psychologically underestimates their company's corporate culture, they will be dissatisfied with the current organizational atmosphere and interpersonal relationships. If they fail to effectively control and eliminate negative emotions, they may develop a tendency to resign or even engage in resignation behavior. Employee recognition of the corporate culture reduces the likelihood of knowledge-based employees resigning. The higher the cultural identity, the lower the probability of knowledge-based employees having a tendency to resign; there is a reverse effect between the two. The overlap of corporate strategies and the sense of corporate culture identity can both reduce the likelihood of knowledge-based employees leaving, but the degree of corporate culture identity has a greater effect on reducing the likelihood of turnover among knowledge-based employees. The job satisfaction of knowledge-based employees can play a mediating role between corporate culture and turnover intention, further amplifying the stimulation of corporate culture and helping companies reduce the probability of knowledge-based employee turnover intention.

Do cognitive abilities reduce eyewitness susceptibility to the misinformation effect? A systematic review.

The fact that memories can be distorted by post-event misinformation has cast considerable doubt over the dependability of eyewitness evidence in legal contexts. However, despite its adverse practical implications, the misinformation effect is likely an unavoidable distortion stemming from the reconstructive nature of episodic memory. Certain cognitive abilities have been reported to offer protection against misinformation, suggesting that mechanisms aside from episodic memory may also be underpinning this type of memory distortion. The purpose of this review was to collate findings of associations between eyewitness misinformation susceptibility and individual differences in cognitive ability in adults aged 18 and over. Nine studies met the eligibility criteria for this review, including 23 distinct associations. Using a narrative synthesis, three categories of cognitive ability were identified as influencing susceptibility to misinformation: general intelligence and reasoning, perceptual abilities, and memory abilities. Across almost all categories, higher levels of ability were associated with reduced susceptibility to misinformation. While there is no indication that any one trait provides total immunity to the misinformation effect, there is a reasonable amount of evidence to suggest that several cognitive abilities create variance in individual levels of susceptibility. Future research should investigate not only if but how these cognitive abilities protect against misinformation distortions, for example, by contributing to more detailed encoding of the memory, enhancing discrepancy detection in the face of post-event misinformation, or improving source-monitoring during an eyewitness memory test.

Students’ Mathematical Reflective Thinking Ability in Solving System of Linear Equations in Two Variables Problems

Mathematical reflective thinking ability is one of the higher-level abilities that can support other mathematical thinking skills. Therefore, ensuring students have good mathematical reflective thinking skills is essential. This study aimed to analyze students' mathematical reflective thinking skills (KBRMS) on the material of a two-variable linear equation system (SPLDV). This research approach is qualitative with a phenomenological type. Data collection techniques were carried out through reflective thinking skills tests and interviews. The study subjects were grade VIII junior high school students who had studied SPLDV material using purposive sampling techniques. Data analysis techniques in this study are data reduction, data display, conclusions, and verification. This mathematical reflective thinking ability analysis is based on indicators of mathematical reflective thinking ability, namely reacting, elaborating, and contemplating. The results of this study show that students can master reacting and elaborating indicators when faced with problems they usually encounter. In contrast, for contemplating indicators, students still experience difficulties when faced with problems different from those traditionally exemplified, such as difficulties in understanding problems and determining the concept of the material used. Based on this, it is shown that students' mathematical reflective thinking skills have not been fulfilled optimally.

Literacy in Pandemic: Practices, Challenges, and Coping Strategies of MKO’s in Online and Modular Learning Modalities

This paper investigated the literacy practices, challenges, and coping strategies of the More Knowledgeable Others (MKO) in helping the learners accomplish literacy tasks included in the online and modular worksheets during the lockdown period because of COVID-19 pandemic. MKO is a person who has a better understanding or a higher ability level than the learner; this includes the teachers, the parents, and the guardians. This study focused on the parents and guardians as they assume two significant roles during the time of pandemic, namely a teacher and a parent. Two hundred six parents and guardians were surveyed, and selected respondents were requested to participate in the semi-structured interview to provide opportunities to express their experiences during the pandemic. The results revealed that MKO’s practices include their role as a: (1) support in children’s school tasks; (2) spending read aloud time with their children; and (3) their use of Internet and gadgets. For the challenges, four subthemes emerged: (1) duality of roles; (2) lack of knowledge and skills; (3) Internet connectivity; and (4) financial challenges. With the challenges come MKO’s coping strategies: (1) managing time wisely; (2) they provide unfathomable moral support; and (3) their faith in God. With the findings, this paper recommends creation of consultative body among parents so they can be included in the curriculum design for the education of their children.

This study aimed to investigate the risk factors related to sleep disorders in patients undergoing hemodialysis using a nomogram model. A cross-sectional survey was conducted in a hospital in Zhejiang province, China from January 1, 2020, to November 31, 2022 among patients undergoing hemodialysis. Dietary intake was assessed applying a Food Frequency Questionnaire. Sleep quality was evaluated by the Pittsburgh Sleep Quality Index. Evaluation of risk factors related to sleep disorders in patients undergoing hemodialysis was using a nomogram model. This study included 201 patients and 87 individuals (43.3%, 87/201) exhibited sleep disorders. The average age of included patients was 51.1 ± 9.0 years, with males accounting for 55.7% (112/201). Results from nomogram model exhibited that potential risk factors for sleep disorders in patients undergoing hemodialysis included female, advanced age, increased creatinine and alanine aminotransferase levels, as well as higher red meat consumption. Inversely, protective factors against sleep disorders in these patients included higher consumption of poultry, fish, vegetables, and dietary fiber. The C-index demonstrated a high level of discriminative ability (0.922). This study found that age, sex, and dietary factors were associated with sleep disorders in hemodialysis patients. Hemodialysis patients with sleep disorders require urgent dietary guidance.

The place and role of the civil sector in the inclusive education and development of children with Williams syndrome (also) through music

Williams syndrome (WS) is an extremely rare genetic disorder. Approximately 1 in every 20 000 people has WS. Because of this, most people have never even met a child with WS. WS occupies a unique place among genetic disorders because of the fact that, in addition to a unique mix of difficulties, symptoms and abnormalities, some of their abilities and performance in certain intellectual areas are adequate or average, and in many cases above average. Relatively high level of ability includes good communication skills, outstanding verbal skills, sociability and good musical abilities with highly sensitive hearing, good musical pitch and musicality, and a very positive attitude towards music. As is typically the case for rare disorders, the most important pillar of their advocacy is the civil sphere, where NGOs and foundations support WS children and families. The great affinity and positive relationship with music justifies that a prominent part of development and inclusion are specifically music-related activities, music therapy activities. The main objective of our research is to map NGOs in Europe and beyond whose activities focus on WS patients and their families. The basis for mapping the organizations is to summarize their aims, activities and achievements and to highlight their music-related activities in line with the mission of inclusion. Our main objective is to show that the development and rehabilitation of WS patients through music and musical activities is a significant and integral part of their care within the organized framework and possibilities of the civil sector.

Study on Resilience Evaluation for Construction Management of Major Railway Projects
