Published: October 2022

Psychological safety of employees is very important for organization functioning and development as it contributes to improved team performance, job involvement, sharing information and knowledge, ensuring their strong desire to continue working and developing in the organization where they work. The purpose of the study is to reveal the organizational factors of psychological safety at a job position, that is to determine, which characteristics of internal organizational condition affect the employees’ perceptions and feelings about a workplace safety. Scientific novelty. This study was carried out to examine the effects of organizational factors on the psychological safety of employees in the workplace. Psychological safety is regarded as a state of preservation of mind that involves maintaining a balance between the negative effects of the environment and a person’s resilience, that is, the ability to overcome such effects. In the structure of psychological safety of the organization member three components were identified: 1) the cognitive component – beliefs of employee about parameters of the professional environment in terms of real and potential threats and his/her own abilities to cope with them; 2) the emotional component – a feeling of being protected from the threats that go from the professional environment. The resulting assessment has emotional shades and can be characterized by dichotomies such as “safe-dangerous”, “good-bad”, “comfortable-uncomfortable” etc.; 3) component “confidence in the future” – in order to feel safe, it is not enough for an employee to perceive the environment as safe and his own ability to cope with all the challenges successfully today, but also the confidence that the current state of affairs will be maintained tomorrow is important. Conclusions. A questionnaire was offered to the members of business organizations and educational institutions. The results of the study confirmed that such organizational factors as level of organizational culture, working team cohesion, working team self-organization, management style of the immediate supervisor, work autonomy, role ambiguity have positive effect on psychological safety. The results imply the importance of purposeful implementation the company policies aiming improvement of these factors. Key words: organization, worker psychological safety, educational institution, business organization, factor, corporate culture, work autonomy, team cohesion.
FORCED MIGRATION CRISIS AND ITS DEMOGRAPHIC CONSEQUENCES
Authors:   Academy of the State Penitentiary Service, Chernihiv, Ukraine, Honcharenko O. G.
Published: October 2022

Scientific novelty. The Russian-Ukrainian war led to a mass migration of the population both within the state itself and beyond its borders, which led to the emergence of the phenomenon of forced migrants, internally displaced persons, refugees, displaced persons, asylum seekers and emigrants in Ukrainian society. A large-scale wave of internally displaced persons and emigrants causes security, social, economic, financial, family and demographic problems. The article determines the trends of Ukraine’s population reduction, which is accelerating the demographic catastrophe, in particular, the increasing in population mortality due to war, huge internal displacements, the growth of emigration (refugees), the decrease in the birth rate and the probable loss of territories. The causes of the migration crisis are established, and its demographic consequences are determined, in particular: the probability of life loss; the impact of the war on the geographical distribution of the population (massive and permanent internal displacement); labor shortage and increasing burden on the pension system, decrease in birth rate (decrease in the number of women of reproductive age); increase in the number of the population of older age groups). It is also proven that the “new age structure of the country’s population” will have a smaller proportion of young people and a larger population of older age groups, which will put additional pressure on the national economy during recovery and reconstruction. Already today, the immediate demographic impact of the war on Ukraine is felt, as it has a “weak” demographic profile. Conclusions. The article substantiates that strong labor relations with employers are one of the important factors of preserving labor potential in Ukraine. However, this aspect has certain challenges for employers, in particular, creating jobs for people who have moved from the war zone (money and access to work remain the main factors for Ukrainian refugees); security guarantees and provision of housing; provision of financial support to victims and others. Key words: migration, demography, migrants, labor potential, war, age structure of the population, internally displaced persons, refugees.
PSYCHOLOGICAL TACTICS OF JUSTIFICATION OF CORRUPTION
Authors:   Taras Shevchenko Military Institute of Kyiv National University, Kyiv, Ukraine, Zarichanskyi O.A.
Published: October 2022

The purpose of the article was to highlight and thoroughly analyze the psychological methods by which corrupt people deny, justify or reduce their own guilt and try to interpret their actions as normal and correct ones. Research results. The article examines psychological techniques of justification (explanation) of corrupt behaviour. It is emphasized that unlike other types of crimes, corruption acts are usually committed by quite respectable and good people, who can be good parents, active members of the community, high officials, and who do not consider themselves as corrupted. One of the most important aspects of corruption is how the offenders defend or justify their actions using various concepts or mental techniques. These methods of justifying corrupt behaviour, which in various studies are called techniques of neutralization, rationalization, socialization, moral disengagement etc., became the subject of this scientific review. The neutralization of deviant behaviour is considered in the article as psychological techniques that help to completely or partially deny someone’s responsibility for deviant behaviour. It is noted that in order for there to be no or less guilt, neutralization can be carried out in two ways: on the one hand, by denying the deviant behaviour itself, and on the other hand, by denying responsibility for it. Conclusions. The leading techniques of neutralization are singled out: disclaimer of responsibility; denial of harm; denial of the victim; condemnation of condemners; appeal to greater loyalty, etc. Key words: responsibility, justification, denial of damage; condemnation, corruption, social norms.

New prospects for drug treatment of chronic cerebral ischemia from the standpoint of neuroinflammation
Authors: Samartsev I.N. , Zhivolupov S.A.
Published: October 2022

The high prevalence of stroke worldwide requires a revision of the modern doctrine of the management of patients with cerebrovascular disease. It is obvious that only aggressive modification of risk factors for vascular pathology does not guarantee the prevention of acute cerebrovascular accident, which is an intermediate or final stage of cerebrovascular disease. In this regard, the use of neuroprotectors, including vinpocetine, can increase the tolerance of brain tissue to hypoxia. Vinpocetine, a derivative of the alkaloid vincamine, inhibiting phosphodiesterase and voltage-dependent Na+- channels is widely used in many countries for the treatment of cerebrovascular diseases, including chronic cerebral ischemia. Recent studies have identified a number of new therapeutic effects of vinpocetine, including stimulation of neuroplasticity via brain-derived neurotrophic factor and inhibition of neuroinflammation. The latter mechanism is mediated by the effect on NF-kB that suppresses the expression of NF-kBdependent pro-inflammatory molecules and prevents the formation of NLRP3 inflammasome. New data allow to reconsider the place of vinpocetine in the prevention and treatment of cerebrovascular disorders, and to recommend its use in a wide range of patients with chronic cerebral ischemia.

The Use of Politeness Strategies in the Realization of the Speech act of Disagreement by EFL Learners
Authors: Jaafar Fatema Abdulla Jaafar , Ageli Nuri R.
Published: October 2022

This study aimed to investigate the differences between the politeness strategies used by university EFL learners and American native speakers in making disagreements. Using Brown and Levinson’s (1978) model, the study examined the variables of gender, social status, and social distance. The participants were 63 EFL learners (41 females and 22 males) and 20 native speakers (10 females and 10 males). The EFL learners who took part in this study were EFL learners who were studying in the Department of English Language and Literature at the University of Bahrain. They were in their fourth, fifth, or sixth year of study. The data was collected using a Discourse Completion Task adopted from a previous study done by Khoirunnisa and Hardjanto (2018) and modified by the researcher to fit the needs of this study. The results of this study showed that the reason why EFL learners seemed more or less polite was that native speakers chose to apply higher or lower percentages of politeness strategies to fit the needs of the different situations, whereas EFL learners used similar percentages of those strategies in most of the situations. This was due to EFL learners’ insufficient competence in the English language. Further, EFL learners were still aware of the necessity of using different politeness strategies in different situations, and thus there were some changes in their use of them depending on the situation. Moreover, the study revealed that female EFL learners used slightly more positive politeness strategies than male EFL learners. In terms of importance, gender was shown to be more important than social status in determining the types of politeness strategies employed by EFL learners.
A Descriptive Panorama of Metacognitive Knowledge among Students in the Moroccan University
Authors: Jarrar Abdelhay
Published: October 2022

One of the key concerns of second language acquisition research is language learning strategies and the extent to which these strategies lead to successful language learning and academic achievement. Indeed, there is a consensus among researchers that learners who take charge of their own learning are academically more likely to succeed than their counterparts. In this respect, a large body of research has proven that metacognitive knowledge is critical in language learning. For this reason, this study is conducted, which is exploratory in nature. It aims at describing Moroccan English department students’ metacognitive knowledge across three geographically distinct schools of art and humanities. Henceforth, the study included 136 participants belonging to three universities, mainly Kenitra, Meknes, and Oujda. To answer the research questions of this study, the respondents were asked to complete a self-report metacognitive questionnaire with a focus on argumentative writing. Findings displayed that Moroccan English university students’ metacognitive knowledge is strong. Furthermore, this study indicated that when age is at play, adults have higher metacognitive knowledge than young learners.
Scorched earth: a posthole approach to Iron Age warfare
Authors: Bornfalk Back Anders
Published: October 2022

In this paper, the author presents a method to identify Iron Age (500 BC – AD 1050) warfare through farmsteads destroyed by fire. Specific fire patterns on individual houses, combined with abnormally high numbers of contemporary burnt buildings, are used as proxy for raised levels of aggression during certain periods. The Uppsala plain in East Central Sweden forms a case study. With this approach, two periods stand out with relatively high numbers of burnt farms: AD 350-425 and AD 500-575. The results are discussed in relation to some source critical factors and to their possible contribution to questions regarding Gamla Uppsala developing into a central place by the 7th century, as well as to the AD 536 event discourse.

In Indonesia, cigarette consumption is quite prevalent and has been become more common over time. According to Riskesdas (Baseline Health Research from Agency of Health Research and Development) study in 2018, the national percentage of people aged who smoke increased from 2016-2018, namely from 3.39% in 2016, 3.9% in 2017 and 9.65% in 2018. Smoking habits will negatively affect human health. Cigarette smoke contains various of different chemicals that are harmful to health, including nicotine addiction, tar (carcinogen or cancer-causing), and carbon monoxide. When inhaled, they form carboxyhemoglobin with Hb (Hemoglobin). When this occurs, the amount of Hb available for oxygen transport is reduced. By way of compensation, the body will produce more red blood cells. The objective of the study was to determine the hemoglobin levels in smokers with smoking durations of 3 years, 4 years and 5 years. This study is quasi-experimental. Determine hemoglobin readings using a photometer 5010 with the Cyanmethemoglobin method. Up to 20 samples were analyzed with SPSS version 20 with Anova analysis at 95% confidence level. The results of statistical analysis showed p-value <0.05, which means that there is a significant effect between variables and vice versa. Hb level comparison between durations of smoking are of 3 years with an average value of 14.8, Hb levels of 4 years with an average value of 14.53, and Hb levels of 5 years with an average value 15.94. The results showed that there was an effect of smoking duration on the results of the examination of hemoglobin levels in smokers of 3,4 and 5 years with the greatest effect being smokers with a duration of 5 years. The duration of smoking impact on hemoglobin levels.

Methodology. The research used methods of general theory of wind power plants, methods of mathematical modeling, which are based on the numerical solution of nonlinear differential equations to evaluate methods for correcting the output power in Matlab-Simulink by modifying standard units. Findings. A numerical simulation mathematical model of an autonomous wind power plant consisting of a magnetoelectric generator with an axial magnetic flux with combined excitation and a double stator has been developed. The model was created to study the parameters and characteristics of the installation, as well as to evaluate methods and means to improve the efficiency of conversion of wind energy into electricity. According to the research, it is established that a more effective method for regulating the output power of the generator in the wind turbine is the use of additional winding for magnetization, compared with the use of additional capacity. The latter provides up to 716% increase in output power, while using the magnetizing winding can increase the output power to 3235%. The results obtained by the authors allow further developing a number of methods to increase the efficiency of conversion of mechanical energy of the wind turbine rotor into electrical energy. Originality. The mathematical model developed for the first time, in contrast to the existing ones, takes into account the presence of a double stator, an additional winding for magnetization of the magnetic system and the axial nature of the circuit of the main and additional magnetic flux. The developed model also takes into account the change in the parameters of the electric generator with axial magnetic flux when changing the parameters of the wind, the rotor of the wind turbine and the load. The model is designed to analyze the possibility of adjusting the output power of the generator when the wind speed changes. Practical value. The simulation results indicate the prospects of industrial implementation of wind power plant based on magnetoelectric generator for their use as autonomous electrical installations and as part of shunting power systems.

Вказано на важливість впровадження в навчальний процес сучасних освітніх технологій для оновлення української школи, акцентовано увагу на ролі в цьому процесі підготовленого педагога, що володіє певним набором професійних компетентностей і здатен генерувати їх для тих, хто навчається. Зосереджено увагу на підходах до формування цифрової компетентності вчителя, яка вимагає від педагога особистісного розвитку та безперервного персонального самовдосконалення. Вказано, що наскрізне застосування цифрових технологій в освітньому процесі має стати інструментом підвищення якості освітнього процесу. Аналіз наукових джерел дав змогу стверджувати, що професійне зростання педагогів в умовах цифрової освіти можливе завдяки підвищенню кваліфікації педагогічних працівників. Проаналізовано Професійний стандарт за професією «Вчитель закладу загальної середньої освіти», у якому зазначено перелік трудових функцій і професійних компетентностей, зокрема виокремлено цифрову компетентність. Обґрунтовано розвиток системи підвищення кваліфікації відповідно до Професійного стандарту вчителя для реалізації права вчителів на професійне вдосконалення шляхом вибору місця і часу підвищення кваліфікації. Досліджено Типову програму підвищення кваліфікації педагогічних працівників з розвитку цифрової компетентності, яка затверджена Міністерством освіти і науки України. Авторами статті розроблені освітні програми, які забезпечують розвиток цифрової компетентності вчителя. Педагогу рекомендовано перед тим, як обрати певну освітню програму, сформувати індивідуальну освітню траєкторію, окресливши для себе ціль та виокремивши певні потреби, мотивацію для професійного росту. Слухачі курсів – це вчителі різних освітніх галузей, які самостійно обирають конкретну освітню програму та мають можливість комбінувати послідовність освоєння тієї чи іншої програми. У статті наведені та проаналізовані результати самооцінювання рівня сформованості цифрової компетентності педагогів різних освітніх галузей згідно запропонованих освітніх програм до початку занять та після завершення онлайн курсів, а також зроблено візуалізацію даних.

The rapid development of media technologies has tremendously influenced all spheres of human life. In media education, they are widely used for both organization of future media industry workers training, and its content.
Being progressive, the media sector makes an active use of the technological capacity to enhance the education efficiency and quality. At the same time, those processes create a tough competitive environment. In the context of the distance learning prevailing in the last few years, higher educational establishments face the emergence of numerous alternative educational internet initiates at the market that may pose a certain threat for the traditional higher education in the future.
It is partially driven by reorientation of media industry’s economic models, including a fundamental revision of approaches to monetization and the popularity of the non-commercial independent journalism with its growing employment opportunities. They all urge journalists gain new skills and pursue knowledge from other spheres often unrelated to journalism. On top of that, changing communication channels and higher technological literacy level of young people shape the need to adopt content formats to new realities.
Seeking to assert their traditional dominance in the media education market, universities should revisit the content of training curricula and more efficiently use technological tools in the educational process.
The current study that is based on the survey of future media workers conducted during 2020-2021 (20 months) made it possible to identify the content formats preferred by students and assess the potential and risks of using them in the future. Described practices of using media technologies by universities allow recommend those of them that could be most efficiently integrated in the educational process. For example, the development of communication channels enabling integration of educational courses and clusters into a single interdisciplinary system both at the level of individual educational units and at the university level seems promising. It would make university curricula significantly more adaptable and competitive in the face of new challenges at the media market and streamline limited resources in the existing circumstances.
The Dimension of Neural Memory and Consciousness
Authors: Marx Gerard , Gilon Chaim
Published: October 2022

The mental dimension is an experiential state achieved by neural circuits, that cannot be measured by physical means but that nonetheless affects the behavior of conscious neural creatures. The “meaning” or “worth” of anything in the life of animals is based on emotive factors that are recalled from past experience. Emotive memory is the key to the “consciousness” that determines decisions and valuations. Even supposedly rational economic decisions are ultimately based on affective considerations. From the Darwinian perspective, neural signaling evolved from bacterial signaling processes which employed small molecules (i.e. biogenic amines). The tripartite mechanism provides a chemodynamic rationale for considering the physiologic basis of such signaling, a key facet of “consciousness”. We note that the original bacterial signaling molecules (i.e. biogenic amines), later termed “neuro-transmitters” (NTs)) were retained by and still used by all neurons. To clarify the discussion, we de-limit the meaning of terms commonly used by both computer scientists and neurobiologists (i.e. “memory”, “information”, “feelings”, “emotions” , “energy”, “artificial intelligence”, “logic” and “dimension”). Mind and body are a complex unity. The psyche emerges from the physiology and chemistry of interacting neurons, projecting an ensemble of physiologic sensibilities into a psychic (mental) dimension. Without memory, there are no emotions and vice versa…without emotive qualities, memory fades. Emotions and memory are linked facets of the psychic dimension of consciousness, encoded and decoded by the biochemically active neural net.
The Role of Emotion Regulation in the Relationship between Coronavirus Pandemic Impacts and Mental Health

Introduction: The Coronavirus pandemic is causing many to experience stressful life events, which are related to the onset or worsening of depressive disorders and anxiety disorders. Emotion regulation plays an important role in responding to stressful life events and in risk for depressive/anxiety symptoms. The current paper examines pandemic- elated negative life events in relation to depressive and anxiety symptoms, and whether difficulties in emotion regulation mediates this relationship. Methods: Participants (N=307) recruited through Amazon MTurk completed questionnaires assessing pandemicrelated negative life events, difficulties in emotion regulation, and depressive/anxiety symptoms. Participants (N=154) completed depression and anxiety symptom measures again 2 weeks later. Results: Pandemic-related negative life events were associated with increased concurrent and longitudinal depression and anxiety symptoms. Emotion regulation mediated the relationships between pandemic-related negative life events and baseline depression and anxiety symptoms as well as follow-up symptoms. Limitations: We did not assess whether participants had previously been diagnosed with a mood or anxiety disorder, so it is unclear whether individuals with these disorders are at an increased risk of worsening symptoms relative to the rest of the population. Discussion: These findings suggest that individuals experiencing stressful events related to the pandemic are at an increased risk for lasting negative mental health outcomes, and that emotion regulation difficulties are a critical target for intervention for these individuals.

Background: Rheumatoid arthritis is a chronic and debilitating immunological disorder that majorly affects joints with swollen and painful characteristics. These patient-reported symptoms worsen their quality of life, which may consequently, predispose them to having major depression. Method: Using a simple random sampling, one hundred and eleven adult patients in the age range of 18 to 64 years with rheumatoid arthritis were cross-sectionally evaluated at the rheumatology Out-Patient Clinic of the Lagos State University Teaching Hospital. The socio-demographic questionnaire, WHO Composite International Diagnostic Interview (CIDI), World Health Organization Quality of Life Scale Short Form (WHOQOL- BREF) were administered to participants to obtain their demographic/clinical variables, make diagnosis of depressive disorder and assess their subjective quality of life respectively. Results: About one-third (n=33; 29.7%) of the participants reported having current depressive disorder. None of the tested variables after controlling for the cofounders was found to be an independent risk factor for current depression among the participants. Conclusion: The prevalence of major depressive disorder is high among individuals with rheumatoid arthritis, and specialists managing this population should routinely screen for depression in patients with rheumatoid arthritis.
Adolescent's Non-Recognition of Cigarette Smoking as a Risk Factor for Dementia: Give me one Cigarette butt! Pilot Study
Authors: Felc Brina
Published: October 2022

The article presents the extent to which pupils and students of Slovenian primary and secondary school are informed about dementia, with an emphasis on their attitude towards cigarette smoking as a risk factor for the development of dementia. The presentation of the research results of a survey between 35 primary school students (13-14 years old) and 35 high school students (16-19 years old) draws attention to the knowledge of the facts about dementia and the poor knowledge of variable risk factors for dementia among high school students compared to with primary school students (p <0.05). The incorrect statement: "Smoking reduces the risk of dementia" was agreed by 20% of high school students and none of primary school students (p <0.05), as well as 10.1% of those respondents who live permanently in rural areas and none of those permanently residing in an urban environment (p <0.05). Educating adolescents about dementia should take into account their knowledge gaps according to their age and place of residence and offer them optimal opportunities for formal and informal learning with an emphasis on a healthy lifestyle that reduces the possibility of dementia in late adulthood
