Authors: Kolisnichenko Anhelina
Published: November 2022

The article analyzes the role of the acmeological approach in the future foreign language teacher training by investigating the main aspects that are as follows: study of the future FL teachers’ personal qualities and abilities, methods of raising their motivation and developing learner autonomy, opportunities for carrying out scientific research and studying the level of higher education institutions readiness to improve the quality of education. It was determined that the development of personal qualities and abilities, as well as the formation of professional competencies, is carried out as a consequence of the acmeological approach, which is integrated into the content of the educational program disciplines compiled for future teachers of foreign languages (English and German). The impact of various motivation types on the acmeological development of future foreign language teachers is clarified and intrinsic motivation is defined as the one that has the greatest stimulus to study. An overview of the possibilities for involving higher education students in research activities was carried out, as a result of which it was recommended to involve future teachers of foreign languages more widely in the realization of their scientific potential. A review of the readiness level of higher education institutions to improve the quality of teacher training has shown that there are positive changes that contribute to the effective process of education, but some recommendations have been identified that will intensively contribute to this process.

FOCUS ON OPTIMISM AND HAPPINESS: PSYCHOLOGICAL FOUNDATIONS FOR DEVELOPING THE SOCIAL WORK CLIENTS’ STRENGTS
Authors: Stoliaryk Olha , Semigina Tetyana
Published: November 2022

Understanding the value and autonomy of the client in the intervention process are postulates on which the modern social work practice is based and which are complementary integrated in a relatively new strengths-based approach (SBA).This paper aims to characterize the theoretical basis of SBA. It is based on a retrospective review of the literature, presenting those psychological concepts on which social work interventions are based, aimed at developing clients' resources and raising their self-esteem and self-efficacy in dealing with life challenges or in solving life’s tasks.It has been determined that SBA is based primarily on humanistic philosophy and positive psychology and seeks or strives to maximize the client's resource potentia in order to improve their quality of life. It's a philosophy and a way to consider clients as resourceful and resilient in the face of challenges. It was found that the implementation of SBA requires the integration of knowledge psychology, in particular the theory of self-actualization (A. Maslow), the need for self-realization (K. Rogers), the development of faith in one's own ability (R. May) , the desire for self-development (J. Bugental), and directions positive psychology - cognitive-behavioral, rational emotional-behavioral therapy (A. Beck and A. Ellis), theory of "learned optimism"(M. Seligman), theory of self-efficacy (A. Bandura) "flow", psychology (M. Csikszentmihalyi), goal-setting (C. Snyder), growth mentality (С. Dvek), understanding of happiness (D. Gilbert), self-determination (K. Sheldon) and strengths perspective (С. Peterson). At the same time, a strengths-based approach combines self-help psychology through the study of self-consistency and the use of psychocybernetics tools. The strengths-based approach as a direction of modern social work is based on such categories of humanistic and positive psychology as "self-concept", self-actualization, potential, resources, subjective well-being, client perspective, experience, positive thinking in order to maximize the client’s resource potential and empowerment, which reinforces its relevance and demand.

Authors: Pavelkiv Kateryna
Published: November 2022

The article presents theoretical approaches to the consideration of the ethical competence of a modern foreign language teacher in his/her professional pedagogical activity. The essence of the concepts “competence”, “professional-pedagogical competence” is revealed, the content of the concept “ethical competence” is characterized. Ethical competence of modern foreign language teacher is defined as an integrative quality of a person, that includes a complex of his/her moral and ethical values and personal characteristics determining the choice of models of teacher’s behavior in various situations of his/her professional pedagogical activity. It has been established that ethical competence as a basic component of professional pedagogical competence of foreign language teacher reflects his/her spirituality and morality, internal culture, the ability to act in accordance with the norms of pedagogical ethics and to take adequate moral decisions.The components included in the model of ethical competence of foreign language teacher are defined, namely: ethical knowledge, communicative skills, psychological position, moral and psychological qualities. The article states that the process of ethical competence formation of foreign language teacher goes through several stages and is a synergistic result of three important components of the educational process: socio-cultural, subject and professionally subjective.The formation of ethically competent teacher is a socially significant problem. The success of education system humanization, the improvement of general culture in society, and the prospects for the development of modern human depend on the solution of the problem mentioned above. Ethical development of a teacher is a continuous process of personal and professional growth, which involves raising of moral awareness level, carrying out professional reflection and formation of the system of attitudes towards the subjects of educational process in accordance with the norms and rules of pedagogical ethics. It was defined that unformed ethical competence leads to ethical and pedagogical errors in pedagogical activity and, accordingly, negatively affects educational process as a whole.

Published: November 2022

OBJECTIVE

Inherited variants predisposing patients to type 1 or 1.5 Chiari malformation (CM) have been hypothesized but have proven difficult to confirm. The authors used a unique high-risk pedigree population resource and approach to identify rare candidate variants that likely predispose individuals to CM and protein structure prediction tools to identify pathogenicity mechanisms.

METHODS

By using the Utah Population Database, the authors identified pedigrees with significantly increased numbers of members with CM diagnosis. From a separate DNA biorepository of 451 samples from CM patients and families, 32 CM patients belonging to 1 or more of 24 high-risk Chiari pedigrees were identified. Two high-risk pedigrees had 3 CM-affected relatives, and 22 pedigrees had 2 CM-affected relatives. To identify rare candidate predisposition gene variants, whole-exome sequence data from these 32 CM patients belonging to 24 CM-affected related pairs from high-risk pedigrees were analyzed. The I-TASSER package for protein structure prediction was used to predict the structures of both the wild-type and mutant proteins found here.

RESULTS

Sequence analysis of the 24 affected relative pairs identified 38 rare candidate Chiari predisposition gene variants that were shared by at least 1 CM-affected pair from a high-risk pedigree. The authors found a candidate variant in HOXC4 that was shared by 2 CM-affected patients in 2 independent pedigrees. All 4 of these CM cases, 2 in each pedigree, exhibited a specific craniocervical bony phenotype defined by a clivoaxial angle less than 125°. The protein structure prediction results suggested that the mutation considered here may reduce the binding affinity of HOXC4 to DNA.

CONCLUSIONS

Analysis of unique and powerful Utah genetic resources allowed identification of 38 strong candidate CM predisposition gene variants. These variants should be pursued in independent populations. One of the candidates, a rare HOXC4 variant, was identified in 2 high-risk CM pedigrees, with this variant possibly predisposing patients to a Chiari phenotype with craniocervical kyphosis.

Published: November 2022

OBJECTIVE

The aim of this study was to summarize the prognosis of recurrent infratentorial ependymomas based on treatment and molecular characterization.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the authors searched the PubMed, Scopus, Embase, and Ovid databases for studies on recurrent infratentorial ependymomas in patients younger than 25 years of age. Exclusion criteria included case series of fewer than 5 patients and studies that did not provide time-dependent survival data.

RESULTS

The authors’ database search yielded 482 unique articles, of which 18 were included in the final analysis. There were 479 recurrent infratentorial pediatric ependymomas reported; 53.4% were WHO grade II and 46.6% were WHO grade III tumors. The overall mortality for recurrent infratentorial pediatric ependymomas was 49.1% (226/460). The pooled mean survival was 30.2 months after recurrence (95% CI 22.4–38.0 months). Gross-total resection (GTR) was achieved in 243 (59.0%) patients at initial presentation. The mean survival postrecurrence for those who received initial GTR was 42.3 months (95% CI 35.7–47.6 months) versus 26.0 months (95% CI 9.6–44.6 months) for those who received subtotal resection (STR) (p = 0.032). There was no difference in the mean survival between patients who received GTR (49.3 months, 95% CI 32.3–66.3 months) versus those who received STR (41.4 months, 95% CI 11.6–71.2 months) for their recurrent tumor (p = 0.610). In the studies that included molecular classification data, there were 169 (83.3%) posterior fossa group A (PFA) tumors and 34 (16.7%) posterior fossa group B (PFB) tumors, with 28 tumors harboring a 1q gain. PFA tumors demonstrated worse mean postprogression patient survival (24.7 months, 95% CI 15.3–34.0 months) compared with PFB tumors (48.0 months, 95% CI 32.8–63.2 months) (p = 0.0073). The average postrecurrence survival for patients with 1q+ tumors was 14.7 months.

CONCLUSIONS

The overall mortality rate for recurrent infratentorial ependymomas was found to be 49.1%, with a pooled mean survival of 30.2 months in the included sample population. More than 80% of recurrent infratentorial ependymomas were of the PFA molecular subtype, and both PFA tumors and those with 1q gain demonstrated worse prognosis after recurrence.

Zero-Sequence Circulating Current Suppression for Parallel Three-Level Back-to-Back Converters Based on DPWM Hybrid Switching Modulation Strategy
Authors: Ding Mingjin , Xie Lei , Zhu Changyu , Zhang Yongmi , Shi Cheng
Published: November 2022

A single wind turbine can no longer meet the increasing installed capacity and reliability requirements. Therefore, the power level and stability requirements of the wind power generation system can be improved through the parallel connection of three-level back-to-back converters. However, the zero-sequence circulating current (ZSCC) will distort the three-phase current, increase the power loss and reduce the system efficiency. Therefore, this paper establishes the ZSCC equivalent model of the back-to-back parallel converter, and analyzes the generation principle of the zero-sequence circulating current. In order to reduce the switching loss of the system and increase the system efficiency, a novel DPWM modulation strategy is proposed. At the same time, in order to control the zero-sequence circulating current of the parallel system, a hybrid switching modulation strategy using DPWM1 and DPWM3 based on hysteresis control is proposed. The simulation and experimental results verify the effectiveness of the zero-sequence circulation suppression strategy for the parallel system.

Published: November 2022

The gasification of COVID-19 plastic waste to methanol was simulated by using Aspen plus software. The effects of main operating parameters on the syngas yield and methanol yield were explored. An industrial Cu/ZnO/Al2O3 catalyst was applied for synthetic methanol production, and the relevant kinetic model was built for the methanol synthesis process. The effects of gasification temperature and pressure on the syngas yields and calorific values of syngas and methanol yields from the gasification of medical plastic waste were discussed. The pressure of the synthetic methanol reactor promoted methanol yields, and the external addition of H2 was optimized for methanol production. It is concluded that the optimal working condition to obtain the highest methanol yield from a suitable HHV of the syngas is when the gasification of plastic waste was carried out at 900 ∘C under atmospheric pressure with an external H2 mass flow of 96 kg/hr and the pressure of methanol synthesis at 47 bar.

Study of Psychological and Behavioral Factors Influencing Public Acceptability of Sustainable Energy Transition in China
Authors: Wang Zijin
Published: November 2022

Replacing fossil fuels with clean and renewable energy sources is crucial to alleviate climate change and its negative impacts. However, the success of the implementation is highly dependent on public acceptability of a sustainable energy transition. This research studied how knowledge about climate change, environment self-identity, openness to change in lives, energy behaviors that can either efficiently (positive) or inefficiently (negative) contribute to energy saving, personal norms, feeling of control over the things around, and worry about China’s energy supply influence public acceptability of sustainable energy transition, with a relatively representative sample in China. As expected, stronger participants’ personal norms explained the increase in their acceptability of a sustainable energy transition. The more negative energy behavior people do in their daily life explained the decrease in the acceptability of sustainable energy transition. The more worry people have about the stability of energy supply in China explained the decrease in the acceptability of sustainable energy transition. The results provided initial evidence about the both psychological and behavioral factors that influence public acceptability of sustainable energy transition in China.

Published: November 2022

With climate change and global warming, there are extreme weather phenomena in some places. Excessive temperature can adversely affect room temperature vulcanized silicone rubber (RTV) insulators. Other factors such as air pollution, dust, fog, rain, ice and snow, and ultraviolet rays can cause damage to the surface hydrophobicity of the RTV surface and reduce its service life. Contamination from the above factors increases the risk of flashover and corona discharge, which can lead to accidents in the transmission system, resulting in economic loss or personal injury. In recent decades, scientists have investigated a variety of materials that can be compounded with RTV to improve their chemical and physical properties in order to extend the service life of RTV insulators. In this review, we conduct an extensive literature survey and summary on the development and application of RTV coated insulators.

Authors: Araruna Fágner D. , Mercado Alberto , de Teresa Luz
Published: November 2022

In this paper we present a null controllability result for a thermoelastic Rayleigh system. Instead of working directly with the control system, we obtain the controlled system as the modulus of elasticity in shear tends to infinity in the corresponding thermoelastic Mindlin–Timoshenko system. Our results follow the seminal book of Lagnese and Lions ( Rech. Math. Appl. 6( 1988 )) where the controllability of a Kirkhhoff model is proposed as the limit of a controlled Mindlin–Timoshenko one. We use estimates for some eigenvalues of the beam model that were obtained in ( SIAM J. Control Optim. 47 ( 2008 ) 1909–1938) and the recent paper of Komornik and Tenenbaum ( Evolution Equations and Control Theory 4(3) ( 2015 ) 297–314) where explicit estimates for systems with real and complex eigenvalues are proposed.

Published: November 2022

This paper investigated the attitudes of 702 college students toward the implementation of fully online learning during the COVID-19 pandemic. Toward this goal, responses of the students were collected and analyzed through hierarchical cluster and sentiment analyses using the R software. Hierarchical cluster analysis revealed hopeful and apprehensive attitudes toward online learning. Advantages of online learning emerged as positive sentiments while challenges and their impact on mental health emerged as negative sentiments. It is concluded that online learning is a promising platform of learning provided that its shortcomings are addressed. Implications to teaching are offered.

Authors: Tan Wei Ying , Hargreaves Carol , Chen Christopher , Hilal Saima
Published: November 2022

Background: The major mechanisms of dementia and cognitive impairment are vascular and neurodegenerative processes. Early diagnosis of cognitive impairment can facilitate timely interventions to mitigate progression. Objective: This study aims to develop a reliable machine learning (ML) model using socio-demographics, vascular risk factors, and structural neuroimaging markers for early diagnosis of cognitive impairment in a multi-ethnic Asian population. Methods: The study consisted of 911 participants from the Epidemiology of Dementia in Singapore study (aged 60– 88 years, 49.6% male). Three ML classifiers, logistic regression, support vector machine, and gradient boosting machine, were developed. Prediction results of independent classifiers were combined in a final ensemble model. Model performances were evaluated on test data using F1 score and area under the receiver operating curve (AUC) methods. Post modelling, SHapely Additive exPlanation (SHAP) was applied on the prediction results to identify the predictors that contribute most to the cognitive impairment prediction. Findings: The final ensemble model achieved a F1 score and AUC of 0.87 and 0.80 respectively. Accuracy (0.83), sensitivity (0.86), specificity (0.74) and predictive values (positive 0.88 negative 0.72) of the ensemble model were higher compared to the independent classifiers. Age, ethnicity, highest education attainment and neuroimaging markers were identified as important predictors of cognitive impairment. Conclusion: This study demonstrates the feasibility of using ML tools to integrate multiple domains of data for reliable diagnosis of early cognitive impairment. The ML model uses easy-to-obtain variables and is scalable for screening individuals with a high risk of developing dementia in a population-based setting.
Beneficial Effect of a Small Pharmacologic Chaperone on the Established Alzheimer’s Disease Phenotype
Authors: Li Jian-Guo , Blass Benjamin E. , Praticò Domenico
Published: November 2022

Background: The endosomal retromer complex system is a key controller for trafficking of proteins. Downregulation of its recognition core proteins, such as VPS35, is present in Alzheimer’s disease (AD) brain, whereas its normalization prevents the development of AD pathology in a transgenic model with amyloid-β deposits and tau tangles. Objective: Assess the effect of targeting VPS35 after the AD pathology and memory impairments have developed. Methods: Twelve-month-old triple transgenic mice were treated with a small pharmacological chaperone, TPT-172, or vehicle for 14 weeks. At the end of this period, the effect of the drug on their phenotype was evaluated. Results: While control mice had a decline of learning and memory, the group receiving the chaperone did not. Moreover, when compared with controls the treated mice had significantly less amyloid-β peptides and phosphorylated tau, elevation of post-synaptic protein, and reduction in astrocytes activation. Conclusion: Taken together, our findings demonstrate that pharmacologic stabilization of the retromer recognition core is beneficial also after the AD-like pathologic phenotype is established.
Exploring Reasons for Differential Vulnerability and Alzheimer’s Disease Risk in Racial and Ethnic Minorities
Authors: Daniel E. Valerie , Kleiman Michael J. , Galvin James E.
Published: November 2022

Background: African American and Hispanic older adults are reported to have up to a 2-fold higher risk of Alzheimer’s disease and related disorders (ADRD), but the reasons for this increased vulnerability have not been fully explored. The Vulnerability Index (VI) was designed to identify individuals who are at risk of developing cognitive impairment in the future, capturing 12 sociodemographic variables and modifiable medical comorbidities associated with higher ADRD risk. However, a prior limitation of the VI was that the original study cohort had limited diversity. We examined the association of the VI within and between non-Hispanic White, African American, and Hispanic older adults with and without cognitive impairment and different socioeconomic strata enrolled in a community-based dementia screening study. Objective: To explore reasons for reported higher ADRD vulnerability in African Americans and Hispanics. Methods: In a cross-sectional study of 300 non-Hispanic White, African American, and Hispanic older adults with and without cognitive impairment, we studied the association between cognitive status, the VI, and socioeconomic status (SES). Results: When considering race/ethnicity, the presence of more vascular comorbidities drove greater vulnerability. When considering SES, vascular comorbidities played a less prominent role suggesting resources and access to care drives risk. The VI had differential effects on cognitive performance with the greatest effect in the earlier stages of impairment. Conclusion: Findings from this study provide a deeper understanding of the differential risk of ADRD in multicultural older adults captured by the VI and how barriers to healthcare access may increase vulnerability in racial/ethnic minorities.

Published: November 2022

Background: A substantial body of research has examined the relationship between alcohol consumption and risk of Parkinson’s disease (PD). Objective: To provide an updated systematic review and meta-analysis of observational studies examining the relationship between alcohol consumption and risk of PD. Methods: Eligible studies comparing PD risk in ever vs. never alcohol drinkers were sourced from six databases. Outcomes were pooled using standard meta-analysis techniques. Separate female and male estimates were generated from studies reporting sex-specific data. Additionally, cohort studies stratifying participants by quantity of alcohol intake were integrated in a dose-response analysis. Results: 52 studies were included, totaling 63,707 PD patients and 9,817,924 controls. Our meta-analysis supported a statistically significant overrepresentation of never drinkers among PD subjects; odds ratio (OR) for ever drinking alcohol 0.84 (95% confidence interval (CI) 0.76 – 0.92). A subgroup analysis revealed similar effect estimates in females and males. A further synthesis of seven cohort studies suggested a negative, dose-dependent association between alcohol and risk of PD. Conclusion: In the absence of a known neuroprotective pathway, there may be reason to doubt a true biological effect. The role of survivor bias, selection and recall bias, misclassification, and residual confounding requires consideration. Alternatively, observations might be attributable to reverse causation if those predestined for PD alter their alcohol habits during the preclinical phase. Major limitations of our study include high between-study heterogeneity (I2 = 93.2%) and lack of adjustment for key confounders, namely smoking status.

In the present work, at first, DFT calculations were carried out to study the molecular structure of the tenofovir at B3LYP/MidiX level of theory and in the water as solvent. The HOMO/LUMO molecular orbitals, excitation energies and oscillator strengths of investigated drug were also calculated and presented. NBO analysis was performed to illustrate the intramolecular rehybridization and electron density delocalization. In the following, a molecular docking study was performed for screening of effective available tenofovir drug which may act as an efficient inhibitor for the SARS-CoV-2 Mpro. The binding energy value showed a good binding affinity between the tenofovir and SARS-CoV-2 Mpro with binding energy of-47.206 kcal/mol. Therefore, tenofovir can be used for possible application against the SARS-CoV-2 Mpro.

Recently, the demand for new renewable and sustainable polymers, as well as their use as precursors to produce energetic materials, has emerged as a popular and burgeoning area of study. In this study, novel energetic nitrogen-rich polymers based on the 1,3,5-triazine ring were synthesized utilizing standard techniques. Four monomers were created initially: 4,6-dichloro-N-(4-chlorophenyl)-1,3,5-triazine-2-amine (A), 1,1’-bis(4,6-dichloro-1,3,5-triazine-2-yl)-1 H,1’H-5,5’-bitetrazole (B), 2,4,6-trihydrazinyl-1,3,5-triazine (C), N-(4-chlorophenyl)-4,6-dihydrazinyl-1,3,5-triazin-2-amine (D) In the second step, seven novel polymers named CHTA, TBT, TBTH, CTBT, THT, CTC, and TCT were synthesized via polyaddition reactions with monomers. Infra-red spectroscopy was used to characterize the nitrogen-rich polymers that were formed (IR). TGA measurements were utilized to investigate the thermal stability of substances. In addition, SEM and 1HNMR were utilized to describe the compounds. The results of thermal analysis indicate that TBT, CTC, and TCT are less stable than other nitrogen-rich polymers. The reaction yield for synthesized energetic polymer were 73%, 92%, 67%, 80%, 84%, 72%and 74%for CHTA, TBT, TBTH, CTBT, THT, CTC and TCT respectively.
Absorbance and emission studies in solution and the solid state and band gap determination of Pri3Ge(GePh2)4GePri3

Published: November 2022

The hexagermane Pri3Ge(GePh2)4GePri3 (1) can adopt four different conformations by rotations about its germanium –germanium single bonds that differ in energy across an energy range of 31.63 kJ/mol, with the trans-coplanar arrangement having the lowest energy. Conformational changes can occur among these four structures resulting in the observation of thermochromic absorbance spectra both in solution and in the solid state. Bathochromic shifts of 5 nm and 15 nm were observed in solution and in the solid state with increasing temperature. Compound 1 is also luminescent both in solution and in the solid state. The solution emission spectra are solvent dependent and the solid state emission maxima were shown to be temperature dependent. When 1 is excited at 300 nm in the solid state at 80 K its emission spectrum contains a broad emission peak in the visible region and this emission can be observed with the naked eye. The indirect band gap of 1 was determined to be 3.25 eV, which is consistent with investigations on other related oligogermane systems.
