Published: October 2022

ObjectiveThere is a growing consensus that interpersonal processes are key to understanding psychotherapy. However, neuroscientific inquiries of therapeutic processes have been limited to (offline) assessments of patients outside of treatment sessions. The current study examines, for the first time, online interpersonal neurological processes between patients and therapists during sessions. Recent research proposes that inter-brain synchrony is a biomarker of interpersonal interaction quality. We hypothesized that over the course of therapy inter-brain synchrony between patients and therapists would gradually increase, and that that this increase – i.e., inter-brain plasticity - would be associated with therapeutic change.Method8 participants enlisted in a 6-session treatment for test anxiety (N = 8 patients). During three of the sessions, therapist and patient brain activity was measured using functional near-infrared spectroscopy (fNIRS), focusing on the inferior-frontal gyrus (IFG). Patient-therapist inter-brain synchrony was calculated using wave transform coherence; perceived session quality, test anxiety symptoms, and therapeutic alliance were assessed using baseline, session-by-session and follow-up questionnaires.ResultsInter-brain synchrony in the IFG was associated with reduced symptoms, improved wellbeing and perceived session quality, but not with a stronger therapeutic alliance. Importantly, inter-brain synchrony significantly improved over the course of treatment, suggesting that inter-brain plasticity has occurred. ConclusionWhile these findings require replication, they demonstrate that fNIRS imaging during psychotherapy is a promising research method, that inter-brain synchrony has potential as an indicator of effective therapy sessions and that inter-brain plasticity might be a biological mechanism underlying therapeutic change.
Lifestyle versus social determinants of health in Dutch parliament: A text mining analysis
Authors: van Baar Jeroen M , Shields-Zeeman Laura , Stronks Karien , Hagenaars Luc Louis
Published: October 2022

Although public health scholars increasingly recognize the importance of the social determinants of health (SDOH), political discourse on health tends to emphasize downstream lifestyle factors instead. We use a text mining approach to analyse a decade of health debate in the Dutch house of representatives, testing three specific causes of the lack of attention for SDOH: political ideology, by which members of parliament (MPs) from some political orientations may prioritize lifestyle factors over SDOH; lifestyle drift, by which early attention for SDOH during problem analysis is replaced by a lifestyle focus in the development of solutions as the challenges in addressing SDOH become clear; and focusing events, by which one-off political or societal events bolster the lifestyle perspective on health. Our analysis shows that political ideology predicted the topics referred to by members of parliament, with left-leaning members referring more to SDOH and right-leaning members more to lifestyle. However, while some parliamentary periods start with an SDOH focus followed by a focus on lifestyle, the pattern is reversed in other parliamentary periods, yielding inconsistent evidence for and against lifestyle drift. Finally, while the ten-year peak in lifestyle-related language coincided with an important political moment around lifestyle (an anti-smoking initiative), the same was true for the SDOH peak (which coincided with a broader prevention program), and both these peaks were rendered relatively insignificant by the larger and more consistent attention for the health care system. This paper provides a first step toward automated analysis of policy debates at scale, opening up new avenues for the empirical study of health political discourse.

Enhancing Postgraduate Taught Students’ Engagement
Authors: Wang Yiduo , Su Zhizhuo , Wang Di
Published: October 2022

Postgraduate Taught Students are a significant part of our student community. To enhance their learning experience and facilitate their learning more efficiently, a storytelling pedagogical approach conducted by postgraduate teaching assistants (GTAs) could be a way to accelerate this process. Postgraduate researchers (PGRs) are important members of the Higher Education teaching community as they provide a unique perspective, from both students and teaching staff. Some of them have a fresh memory of their learning experiences and thus could better understand the students’ concerns. This paper reports the experience of PGRs and GTAs regarding sharing personal stories to help students understand and overcome their challenges in academic writing. The storytelling pedagogy in practice indicates a significant effect in supporting not only academic study but also students’ engagement and reflection. The usage of storytelling pedagogy also aids in the concept explanation of technical elements in texts by offering succinct and tangible instances, which assist students in developing their critical thinking skills and individualised understanding of factual material.
The Development of Teaching, from Covid-19 to in-person Laboratory Sessions
Authors: Slade-Harajda Tobias
Published: October 2022

Teachers who began, like myself, teaching during the Covid-19 pandemic have had to adapt to multiple ways of teaching to accommodate the switch in demand of the student to different styles and methods. What was once dominated by in-person classrooms of 30+ students became a mix of independent learning and tutoring. Those who started their teaching journey through online one-on-one tutoring sessions bolstering up in-person classrooms, have had to adapt to the old method of teaching with students who are used to hiding their faces and muting their microphones. In this article I discuss how my method of teaching has changed, my opinion on the importance of physical presence in a classroom and what we can learn from the teaching styles demanded by the student.
Setting up the Superb-Vision Network: Establishing a “dispersed learning community”
Authors: Sinclair Ben , Lu Bing
Published: October 2022

As universities gradually re-open to face-to-face teaching, innovative approaches that encourage engagement and stimulation in the “new normal” have been readily welcomed. The Superb-Vision Network (SVN) was a response to such a call: a series of student-led workshops to support doctoral students in enhancing their supervision experience. This article is a reflection on the process of setting up the network. We will explain the decisions and actions taken and explore several critical incidents which demonstrate what collaboration between those with dissimilar perspectives and backgrounds can look like in practice. Considerations around sustainability, inclusivity, and safety posed additional challenges that vastly shaped our thinking and plans, allowing us to find balance in our social and educational outcomes. Informed by the notion of “distributed” learning (Lea & Nicolle, 2013) and “dispersed” pedagogic  system (Boud & Lee, 2005), this article advocates facilitating a “dispersed” learning community for doctoral students with an emphasis on peer learning (Boud & Cohen, 2014). We hope that this interesting case study will motivate and inspire others to use opportunities, however small, to add value to their community.
Afterword: Colleagues and Care
Authors: Hattersley Sara
Published: October 2022

The experience and positionality of PGR teachers is well documented in academic papers, surveys, and discussions in our institutions. In the wake of the pandemic how should we conceptualise their role? What is their place? With reference to the University of Warwick specifically, but looking more widely, this afterword considers the PGR teacher experience, role, and identity alongside a perceived shift in the conversation about what matters now in Higher Education. It argues for a re-imagining of the PGR teacher role alongside more senior colleagues, who should take action to advocate in ways that will break through the liminality.
Моделювання сейсмічних ефектів при зміні фізичних властивостей геологічного середовищана прикладі Одеського газового родовища
Authors: Габльовський Б. Б. , Ганженко Н. С. , Розловська С. Є.
Published: October 2022

The paper deals with the methodology and results of seismic modeling performed on the example of the Odessa gas field located within the north-western shelf of the Black Sea of the Southern oil and gas region of Ukraine in order to assess the possibility of using seismic monitoring in the development and operation of oil and gas fields. The geological structure of the Odessa gas field allows to clearly demonstrate the nature of the change in the dynamic characteristics of the seismic record when changing the physical properties of the geological environment. To assess the seismic effects, time sections were modelled for two models of environments with different porosity values, the waveform change was analysed, the time shift between the maximum amplitude values within the productive sediments was calculated, and the reflection coefficients of the longitudinal wave at normal beam incidence were calculated, and the instantaneous phases, amplitudes and instantaneous frequencies of seismic recording were calculated by Hilbert transformation. The conducted studies allow us to draw conclusions about the degree of contrast of the dynamic characteristics of the seismic recording and the possibility of using them to monitor the state of oil and gas fields. According to the simulation results, it was established that the change in porosity in different productive horizons of the Odessa gas field has a different reflection in the seismic field. In particular, to control the physical state of the productive horizons of the Upper Paleocene and Lower Paleocene, a more informative indicator is the temporal shift, and the productive horizon Eocene-1 is the instantaneous amplitude. The choice of the indicator depends on the seismic and geological conditions of a particular deposit or research area, and the involvement of dynamic characteristics of the wavefield in solving seismic monitoring problems requires a high quality of seismic information.

Published: October 2022

З використанням програмних комплексів Eclipse та Petrel досліджено підвищення вуглеводневилучення газоконденсатних родовищ із високим вмістом конденсату в пластовому газі. Метою роботи є оптимізація технології підтримання пластового тиску з використанням сухого газу. Дослідження проведено для різних стадій виснаженості газоконденсатного покладу. Тиск початку нагнітання сухого газу в поклад становить:1 Рпоч; 0,8 Рпоч; 0,6 Рпоч; 0,4 Рпоч; 0,2 Рпоч. Відповідно до результатів проведених досліджень установлено, що у випадку впровадження технології нагнітання сухого газу в газоконденсатний поклад підтримується пластовий тиск на вищому порівняно з розробкою на виснаження рівні. Завдяки цьому технологічні режими експлуатації видобувних свердловин стабілізуються та забезпечується додатковий видобуток вуглеводнів. Накопичений видобуток конденсату залежно від тиску початку нагнітання сухого газу в продуктивний поклад становить: 1 Рпоч – 398,25 тис. м3; 0,8 Рпоч – 384,73 тис. м3; 0,6 Рпоч – 371,46 тис. м3; 0,4 Рпоч – 360,69 тис. м3; 0,2 Рпоч – 345,22 тис. м3. Аналізуючи результати проведених досліджень, встановлено, що чим вищий пластовий тиск в газоконденсатному покладі на момент впровадження технології нагнітання сухого газу, тим більший накопичений видобуток конденсату. На основі результатів аналізу розрахункових даних визначено оптимальне значення тиску початку нагнітання сухого газу в газоконденсатний поклад, яке становить 0,842 Рпоч. Кінцевий коефіцієнт конденсатовилучення для наведеного оптимального значення тиску початку нагнітання сухого газу в поклад збільшується на 7,26 % порівняно з розробкою на виснаження. Результати проведених досліджень свідчать про високу технологічну ефективність впровадження технологій підтримання пластового тиску при розробці газоконденсатних родовищ із значними запасами конденсату.

Authors: Паневник Д. О.
Published: October 2022

Побудовано номографічні залежності для визначення додаткового напору низьконапірного та високонапірного струминного насоса при його асиметричному обертанні в свердловині. Для номографування рівнянь характеристик струминного насоса введено узагальнений безрозмірний параметр у вигляді співвідношення квадратів колової швидкості та швидкості потоку на виході з робочої насадки. Введений параметр є функцією кутової швидкості обертання струминного насоса, відстані між осями свердловини та струминного насоса, витрати та радіусу робочого потоку. Дане співвідношення представлене за допомогою сіткової номограми шляхом введення в задане рівняння допоміжних змінних і розкладання його на чотири окремих вирази, кожен з яких має три змінні величини. Отримана номограма має вигляд суміщення чотирьох квадрантів. Номограма для безпосереднього визначення додаткового напору низьконапірного струминного насоса містить два бінарних поля та одинарну шкалу. В процесі номографування характеристики високонапірного струминного насоса попередньо отримано роздільну двофакторну залежність між трьома змінними величинами, одна з яких є шуканою. При побудові статистичної залежності отримано параболічні криві з точкою сходження в початку координат і показником степеня більшим одиниці та гіперболічні криві з асимптотами у вигляді осей координат. Вирівнювання нелінійних графічних залежностей здійснювалось використанням нерівномірної (зокрема логарифмічної) шкали. Показники степеня отриманого статистичного рівняння визначені за кутом нахилу вирівнених графічних залежностей. Номограма для визначення додаткового відносного напору високонапірного струминного насоса передбачає використання двох бінарних полів та рівномірної вертикальної шкали. Визначення додаткового напору за допомогою отриманої номограми графічно полягає у пошуку координати четвертої вершини побудованого паралелограма.

Published: October 2022

The goal of this research experiment is to create a biological preparation based on predatory nematodes to control potato pests. 15 isolates of entomopathogenic nematodes were isolated: 13 were isolated from coniferous and mixed forests; 2 from soils of agricultural fields: 1 from a potato field, 1 from a field sown with perennial grasses. Nematodes were identified as Steinernematids based on the color of the corpses of larvae of Galleria mellonella and the morphology of males. Isolates of entomopathogenic nematodes from various habitats (forests, agricultural fields, grasslands) of Akmola and Pavlodar regions were isolated. Screening of isolates on the larvae of the seed nutcracker (Agriotes obscurus) was carried out. It is stablished that the wireworm is sensitive to all isolates. Of the 15 isolates tested, 12 of these isolates showed high mortality ability in relation to wireworm: about 50–70 % mortality in laboratory biotests; 3 isolates (AF 15, AF 22, and AS 36) could not cause more than 40 % of the average mortality of larvae. The screening results showed that the isolates AF 29, AF57, and KP76 are good isolates for further studies as a possible bioinsecticide agent against A. obscurus.

In recent years, studies of serotonin in physiological and pathological processes of the body have widely discussed its role as a link in the pathogenesis of atherosclerosis, arterial hypertension, and coronary heart disease. In the embryonic period, serotonin acts as a growth factor and plays an important regulatory role in the decisive period of embryo development, particularly, in the development of the heart. This research aims to study the influence of serotonin on the temporal parameters of contraction of the myocardium of the right ventricle in the newborn pups with a blockade of serotonin synthesis and membrane transporter in the embryonic period of ontogenesis. Thus, these studies have shown that the response of cardiomyocytes to serotonin is statistically higher in the group with excess serotonin and lower in the group with serotonin deficiency compared to the control group. The article also presents data indicating the change in serotonin concentration, which was created by the blockade of serotonin synthesis and the membrane transporter of serotonin in the embryonic period of ontogenesis, which results in morphological changes in the myocardium in early postnatal ontogenesis.

В статье рассмотрены научные данные о функциональном состоянии живого организма при корона-вирусной болезни (COVID–19). Цитокины — низкомолекулярные белки, секретируемые иммунными клетками организма, при нормальном количестве обладают защитным для организма действием, связанным с отграничением повреждённой ткани при воспалении. В настоящее время известно более 30 видов, которые по структурным особенностям и биологическому действию делятся на несколько самостоятельных групп. Повышенное высвобождение цитокинов в ответ на вирусную инфекцию, известное как синдром высвобождения цитокинов или цитокиновый шторм, становится механизмом, приводящим к острым респираторным дистресс-синдромом (ОРДС) и полиорганной недостаточностью (ПОН) при COVID-19, тем самым подтверждая гипотезу о том, что правильно подобранные противовоспалительные терапевтические стратегии могут улучшить клинические результаты и прогресс пациентов. Так как единых диагностических критериев «цитокинового шторма» на сегодняшний день не существует, в лабораторной диагностике в первую очередь, обращают внимание на повышение интерлейкина-1β (ИЛ-1β), интерлейкина-6 (ИЛ-6), С-реактивного белка (СРБ) и ферритина, прокальцитонина.

The article aims to study the management of the innovative economy in the context of sustainable development within an institutional and matrix clusterization model in the context of adaptive human resource management, the digitalization of the agricultural and food sphere and adaptation to the COVID-19 pandemic. Methods. The following special methods of scientific cognition were used in the research process: historical-logical method; method of systematization, classification and theoretical generalization; method of institutional analysis; method of system analysis; method of logical analysis and synthesis; method of graphic analysis. Results. The evolution of the effect of collaboration and achievement of synergy within clusters under different types of economic systems has been determined. It is shown that in a post-industrial economy there is a very strong effect of intra-cluster collaboration, which is due to the dominance of a super competitive environment and mutually beneficial cooperation between government, business and science. The formation of institutional and matrix clusterization in the system of the innovation economy is proposed. It is shown that the effectiveness of institutional and matrix clusterization is ensured by a high degree of its stakeholder communicativeness. Practical contribution. The directions and ways of development of clustering of innovative entrepreneurship, combining the characteristics of effective network cooperation with the participation of large leading enterprises in the form of cluster models "wheel and spokes", "satellite" cluster, provide an opportunity to plan at the macro, meso and micro levels innovation clusters taking into account the strategic priorities of economic development. Prospects for further research. Technological, human, material and information exchange with the changing external environment is constantly taking place in the innovation cluster. Such environment is characterized by a set of economic entities with which innovation, material and information interchange (innovation, products, personnel, services, finance, marketing communications, etc.) takes place constantly. The main feature of institutional and matrix clusterization is the emergence of synergistic effect and, as a consequence, the formation of mutually beneficial cooperation in the network system.

The main feature of the work of hospitality workers is constant communication with people of different ages, social statuses, and sometimes nationalities. The culture of professional communication of service workers consists, first of all, in respectful attitude to the client, and also in ability to interact with the person irrespective of a situation. The professional ethics of the hospitality industry is based on professional knowledge, skills, moral norms and principles, as well as basic aspects of professional, social (including moral, pedagogical, political, diplomatic, internal, emotional) culture and professional etiquette.

When visiting the guests of the institution, it is very important to match the manners, appearance, language, gestures and clothes. If employees violate their professional ethics, violate morality, forget about their professional standards, it leads to a negative image of the hotel and restaurant business.

The ability to ethically, competently and meaningfully express an opinion, provide information to the client is a necessary and extremely important component of the communicative competence of employees in the hospitality industry. This component is the foundation of business processes of the industry, which is aimed at promoting and selling tourism products, hotel and restaurant services, sightseeing, spa and specialized services. In view of this, the skills of professional communication are of great importance in both international and international dialogue.

The global pandemic COVID-19 had a serious impact on the dynamics of air traffic. The purpose of this article is to analyze the change in air travel over the past 10 years and to describe the potential situation, threats and suggest alternative ways out of the crisis. As a result, we identified the following problems: insufficient funding for the aviation industry, lack of resources necessary for its development, low level of exports of civil aviation, no credit mechanisms to finance the production of aircraft, lack of incentives for domestic and foreign institutions to invest, lack of control over aviation companies . The largest decline in air travel occurred in 2020. We also see a decrease in flights from 2013 to 2014 in connection with the beginning of military clashes in eastern Ukraine. In 2021, new air carriers entered the Ukrainian market, including Flynas (low-cost carrier of Saudi Arabia) and Eurowings (German low-cost carrier). It was found that domestic flights through the airspace of Ukraine have increased. An important impetus for their growth is the development of regional airports with the prospect of creating a National Airline. The positive dynamics was influenced by the opening of new passenger flights (Kyiv-Uzhhorod, Chernivtsi-Kryvyi Rih) and the adoption of the draft law №5301, which extended the term of granting Ukrainian airlines a transitional period for the transition to the use of domestic aircraft. In the summer of 2021, flights resumed, and Ukrainians are actively flying to Turkey, Egypt and the Dominican Republic - the most popular destinations. As for Ukrainian airports, their passenger traffic has decreased significantly since 2019, more than twice. Therefore, we propose to look for ways to reduce airport costs and fees, reduce aircraft fleet to save on their maintenance, reduce staff, refocus on charter flights, reduce the tax burden and encourage investors, which is especially important.

Abstract. The mechanism of application of new methodical approaches to definition of influence of internal indicators (factors) of development of labor potential of the enterprise on results of financial and economic activity of the enterprises by use of the special mathematical device - methods of the factor analysis is opened. To conduct such a factor analysis is an extremely important problem is the choice of indicators that adequately reflect the forms of manifestation of the essence of the phenomenon under study.

The practical significance of the study. In our case, 67 indicators were selected for three enterprises, which characterize the labor potential of these enterprises. From them, as a result of using the tools of mathematical statistics, were selected 36 most valuable, which served as useful information for factor analysis, as a result of which the authors obtained a matrix of factor loads of indicators characterizing the labor potential of the studied enterprises. As a result, the most significant factors of influence were identified for each of the studied enterprises, taking into account how it is possible to effectively manage the development of labor potential of the enterprise in the direction of improving the results of their financial and economic activities.
