Around 170 early career researchers (ECRs) from 8 countries were interviewed about the whole range of their scholarly communication attitudes/behaviours during pandemic times and this paper analyses what they said about predatory journals in a wide range of scholarly communication contexts. Because of the delicacy of the topic there was just one question exclusively directed at predatory journals, which asked about policies rather than actions, which yielded nevertheless wide-ranging comments on the topic. ECRs also volunteered information on predatory journals in another half dozen questions, most notably including one on questionable research practices. The source of data was mainly the final interview of three undertaken, with some comparisons made to rounds one and two. Findings disclose the existence of a whole raft of formal and informal assessment policies/coded that direct ECRs to legitimate journals and away from predatory ones. Despite being junior, ECRs are very accultured to the criteria of what is considered as prestige and quality and believe predatory publishing is not even conceivable. They are far more concerned about low-quality research, preprints and borderline ‘grey’ journals. The pandemic has increased the level of questionable practices and low-quality research, but predatory journals were only singled out by a relatively small number of ECRs.

Published: January 2023

Biogas production from lignocellulosic biomass has gained attention in the development of renewable fuels. Corn stover belongs to lignocellulosic biomass. Pretreatment is needed to help the digestion of biomass due to its lignocellulosic recalcitrance. This study aims to compare the different types of acids for enhancing biogas production. The experiment was carried out in a 1 L batch digester at room temperature with different acids of HCl, H2SO4, and C2H2O4 at concentrations of 0%, 5%, 10%, and 15%. The acids pretreatment was performed for 24 hr. Results show that pretreatment of C2H2O4 has a positive impact on increasing biogas yield. The highest cumulative yield of 580.8 mL/gVS is obtained at 15% C2H2O4. The increase in acid concentrations decreases the initial pH value. The pH value below 6 reduces biogas yield.

The role of the facilitator in the context of subject-subject pedagogical communication
Authors: Omelchenko L.
Published: January 2023

The article is devoted to the problem of pedagogical facilitation. The dominant role of information technologies, the transition to mixed (face-to-face-distance) learning, the necessity to create a safe educational environment, caused by the full-scale war of russia against Ukraine, determine the urgent need for the teacher to master a new role - the facilitator. It is substantiated that pedagogical facilitation is the effect of pedagogical interaction that occurs in subject-subject communication, the essence of which is to actualize personal creative potential, improve the productivity of interaction by facilitating the process of educational and professional activity. Determinants of the specified process are a special style of interaction, the presence of the teacher's personal qualities that determine the possibility of performing the role of facilitator. It has been proven that the most acceptable professional position of a teacher is a partner position, since it is a position that gives the opportunity to implement the principle of equality (subjectivity). In order to realize the professional role of a teacher-facilitator, it is important to be aware of social expectations: a dignified attitude to the student's personality as the highest value, centering in pedagogical activity on the needs of the student and on the realization of one's own professional need for self-development, self-improvement, establishing harmonious relationships on the basis of morality and spirituality. The content of the activity of a teacher-facilitator is to create a psychological atmosphere, an intellectual field, to observe the activities of students, to model the interaction of students, and to activate their activities. The congruence, acceptance and empathy of the teacher will contribute to the formation of trusting relations between the teacher and the students, which is a guarantee of the opportunity for each partner to manifest his own subjectivity.

Authors: Kultenko V.
Published: January 2023

In the modern world there are paradigmatic changes caused by the full-scale invasion and military actions of the Russian Federation against Ukraine. The long and bloody war came as a surprise to the world in terms of character, content, and possible consequences. The heroic resistance of the Ukrainian people, steadfastness in defending their own freedom and the right to self-determination forced the world to reconsider its attitude to Ukraine. After all, during this war, in the eyes of the world, a renewed political subject Ukrainian nation is being formed, which is fighting for its right to exist with weapons. Such activity of Ukrainians requires a corresponding reaction from the world, because after February 24 the world has changed and is being tested for strength: from the threat of nuclear war to global food or migration crises. Another essential test for the world was the crisis of existential and moral choice. The aim of the work is to study the complex socio-historical circumstances in which the formation of Ukrainian political identity on a new worldview platform, when the rational order of things is displaced and replaced by irrational-volitional factors of life.

Theoretical principles of applying situational learning technology in the training of future social workers (on the example of teaching the educational discipline "Fundamentals of scenario work and art therapy")
Authors: Osadchenko Inna
Published: January 2023

The article, based on the analysis of scientific sources and empirical material, characterizes the theoretical principles of the application of situational learning technology in the training of future social workers (on the example of teaching the educational discipline "Fundamentals of scenario work and art therapy"). The professional activity of future social workers is described as situational activity, during which one type of professional situation is replaced by another or prompts the emergence of another professional situation. In order to learn to make the right decisions, it is necessary to train this ability, and therefore full-fledged professional knowledge and skills can be obtained only by developing situational thinking in the process of situational analysis. The analysis of a real educational situation by roles in classes on the discipline "Fundamentals of scenario work and art therapy" will help future social workers to form their own attitude towards it, gain experience through the game, promote the development of imagination and critical thinking skills, the ability to find and consider alternative options for actions, sympathize with others It is noted that the modern professional development of future social workers should be implemented through the introduction of a didactically justified solution to a wide range of professional situations in the process of teaching the educational discipline "Fundamentals of scenario work and art therapy". One of the contradictions of professional training is emphasized: between the traditional approach to the didactic system of training future social workers and the realities of educational activity, which requires situational mobility from the specialist, which is the result of special situational training with the use of appropriate technology.

Study Design: Cohort study.Purpose: There is currently no published study that focuses on the spinal corrective surgery effects with cranial parameters in adult spinal deformity (ASD) patients. It is an important factor to measure since it plays a critical role in maintaining the line of sight. The objective is to determine the change in cranial parameters using the slope of McGregor’s line (McGS) after ASD surgery after 2 years of follow-up.Overview of Literature: A study concluded that cervical spine alignment (C2–C7 lordosis) is strongly affected by thoracic kyphosis (TK). Another study showed that patients with ascending gaze had significantly more thoracolumbar malalignment.Methods: This retrospective study includes 295 corrective surgery patients with ASD. Subjects were divided into two groups after propensity age matching analysis: cranial malalignment (McGS <−8 or >13) and normal cranial alignment (−8≤ McGS ≤13). Lumbar lordosis (LL), pelvic tilt (PT), TK, cervical lordosis (CL), and sagittal vertical axis (SVA) were evaluated between the two groups.Results: SVA (95–56 mm) and PT (34°–25°) decreased and LL (19°–41°) increased 2 years after surgery (p <0.05), but McGS (−1.1° to −0.5°) and CL (21°–19°) did not change. Conversely, in the group with cranial malalignment, SVA (120–64 mm), PT (35°–26°), and LL (12°–41°) showed similar results to the normal cranial parameter group 2 years after surgery, but in contrast, McGS (−13° to −2°) and CL (24°–18°) improved significantly.Conclusions: Severe ASD adversely affects to maintain horizontal gaze but can be improved by spinal corrective surgery.
Selection of the optimal neural network of a Smart building system for object recognition
Authors:   State University of Telecommunications, Horelov A. I.
Published: January 2023

Recently, artificial intelligence has captured a number of solutions that help us in everyday life. It will not surprise anyone now. It is in every modern smartphone and helps us to search, sort and process information faster. Today, smart home systems have taken a significant place among the developments in the field of information technology. The huge amount of data generated in them and the variety of formats of this data does not allow to create a universal mechanism for their productive processing. Therefore, the integration of neural networks, which is best suited for individual tasks, will provide us with high efficiency of smart home systems with minimal errors in decisions. Year by year, the interest in solving more complex tasks of object recognition is growing, due to automation needs for shaped communication processes in intelligent systems. Therefore, improving the implementation of the recognition of computer image systems is relevant. One of the promising directions for solving this problem is based on the use of artificial neural networks and neurocomputers as the most progressive in relation to the problems of classification of pattern recognition tasks. In our time, a large number of neural network architectures are proposed for application in the recognition of objects. The analysis of the proposed solutions shows that there is still no such model that would be the best among all the resulting performance parameters. Prospects for the improvement of architecture are seen in convolutional neural networks. The advantages of roller networks over multilayers are to use a common weight in the roller coasters, which means that for each pixel of the layer is used the same filter.
Data processing by end devices in IoT systems
Authors:   State University of Telecommunications, Shram M. M.
Published: January 2023

Internet of things (IoT) systems are making a significant contribution to the growth of global traffic. There is a tendency towards a decrease in the volume of transmitted and stored data, for which various approaches are used. Most of these approaches involve traditional cloud and gateway processing, leaving the endpoints idle in the process. The article discusses the correlation method of data processing on the end device. The results of the study of the maximum performance when implemented on FPGAs with different orders of the matched filter N and different bit widths of the input data stream are presented. A huge number of devices have been connected to the network for a long time. On the Internet of Things, communication must occur between things (without human intervention). This paper presents a correlation method for processing data on end devices and reducing the amount of data transmitted over the network. Instead of expensive and complex network devices, developers can use cheap and proven low-speed Internet of Things (ZigBee, NB IoT, BLE) solutions for data transfer. The novelty lies in one of the features of this approach: the use of components for analysis, rather than a complete copy of the signals, as well as processing directly on the sensor. The advantage of this approach allows you to reduce the number of operations and complexity of implementation, in contrast to other methods focused on the cloud computing paradigm. We provide results for correlation values and the number of logical elements (LE) when implemented on the FPGA, depending on the number of elements in the correlator. This allows to maintain a balance between the required calculation accuracy and spent hardware resources, as well as to simplify the end device.

The method of transformation of the model of the organizational and technical system into the model of the information system
Authors:   State University of Telecommunications, Kolumbet V. P.
Published: January 2023

A variety of systems and decision-making processes have their own characteristics. First of all, these problems are difficult to describe algorithmically. Decisions are made according to certain scenarios, for the description of which it is advisable to use knowledge bases and expert system technologies. When automating the activities of a decision maker, software intelligent agents can be used. Therefore, for such processes, the information system should include a decision support system that will help the decision maker, based on the available information, correctly identify the problem and choose the optimal solution. It should be noted that all algorithms and behavior scenarios are subject to complete formalization. In some cases, the direct participation of the decision maker is required. Organizational and technical systems are characterized by decision-making processes that involve working with knowledge, are formalized by scenarios, and in some cases involve the coordination of decisions. The effect of informatization will be much higher if the task of automation is solved together with the task of improving business processes. At a certain stage of the analysis of the terms of reference and business processes, it is necessary to develop a conceptual model: to identify and describe the main objects and the relationships between them, in order to formalize the subject area of the organizational and technical system, which, in the future, must be transformed into a conceptual model of the information system. The article discusses a method for transforming a model of an organizational and technical system into an information system model, which is formed as a set of diagrams of functional and object-oriented approaches based on the use of conceptual domain models. This method allows building a one-to-one correspondence between the conceptual model of the subject area of the organizational and technical system and the model of the information system.
Stochastic model for determination of arbitrariness and completeness of information system
Authors:   State University of Telecommunications, Zamriy I. V.
Published: January 2023

When evaluating information system reliability indicators, the necessary initial data for a priori probability calculations are often missing, and statistical evaluation is complicated by a large amount of tests, which can only be used to determine the estimates of the moments of the determining random variables of the process of functioning of the information system or its constituent parts (mathematical expectation and variance of failure time processing, recovery time, backup time, etc.). However, in this situation, it is necessary to justify some characteristics of the information system, for example, time reserve, guaranteed exact limits of the probability of fault-free operation of the system and availability coefficient. In this case, «justification» means the construction of precise upper and lower limits of the change of functionals, which characterize the efficiency of the functioning of the information system, in the conditions of incomplete a priori information about the distribution functions of the determining random variables. In this paper, an N-periodic set of information states with one risky and one risk-free process is considered, the arbitrariness and completeness of this set is investigated, and the entropy for the Radon-Nikodym derivative of the corresponding equivalent martingale measures is found. Conditions for the signal loss distribution function were also found, under which the set of signal states is arbitragefree and complete. It is shown that the use of the proposed signal change function made it possible to effectively investigate a set of information states for impartiality and completeness. The application of the obtained results to the determination of the fair price for the аsian arithmetic option with the initially specified payment function is considered.

In conclusion, cod liver oil supplementation on commercial feed controlled blood glucose levels, and there was no disturbance in the histological structure of the pancreas of male rabbits.Keywords: fatty acid, glucose, cod liver oil, pancreas, rabbit
Little Grey Men? Animals and Alien Kinship
Authors: Swart Sandra
Published: January 2023

This essay confronts the lack of vernacular, indigenous or local knowledge in human-animal history and pushes it back into Deep History. It analyses the shifting meanings of the occult baboon and the alien 'other' in South Africa's syncretic and synchronic cosmologies. It asks why it is the baboon - out of all the animals - who came to be a witch's familiar? It asks why the tokoloshe, a supernatural sprite, became baboon-esque? In answering these questions, it uses Freud's notion of 'alien kinship' - the ancient attraction and anxiety induced by baboon as the uncanny, the alien, the changeling, the shape-shifter - or the 'Other within' us. It examines not only the changing role this understanding of the supernatural baboon has played in human societies historically (including a new role created by the tabloids) but the concomitant consequences for baboons themselves - to show that 'animal history' can advance a 'usable past'.
Human-Animal Relations and Livestock Disease Management in Postcolonial Zimbabwe, c.1980 to 2022
Authors: Mwatwara Wesley
Published: January 2023

The history of livestock disease management strategies in colonial Zimbabwe has generally revealed uneven and racialised access to conventional veterinary facilities that favoured white- over black-owned livestock. In light of this context, this article examines the human-animal relationships that emerged in post-colonial Zimbabwe when access to such facilities was liberalised in a new era in which communal livestock owners still had broken interrelations with the state. In articulating this, it also explores factors that precluded communal livestock farmers from raising 'healthy' livestock. Using qualitative methods, it discusses how the postcolonial state failed to provide robust state veterinary services, and demonstrates communal farmers' agency amidst loss to epizootics and enzootics. As this study will show, livestock diseases and the challenges they posed significantly impacted on how humans (communal farmers) determined which animals to raise and how to raise them. It concludes that livestock diseases and the human-animal relationships that emerged out of the quandary posed by the former, had a negative impact on state-communal livestock farmer relationships, and promoted the continued relevance of otherwise officially despised livestock knowledge regimes in Zimbabwe's communal areas.
Review of 31 cases of neonatal gastrointestinal perforations
Authors: Ali Almoamin Haithem H.
Published: January 2023

Background: Despite the recently improved neonatal intensive management, gastrointestinal perforation during the neonatal period is still a major challenge for pediatric surgeons.Objective: To review the effects of different clinical and operative parameters on the mortality of neonatal intestinal perforations.Patients and Methods: A retrospective study was done to 31 cases of neonatal intestinal perforation at the neonatal intensive care unit of Basrah children speciality hospital during the past four and half years (July 2011 to December 2015). Information regarding the age, sex, gestational age, birth weight, clinical examination, x-rays value in diagnosis, causes and sites of perforations, types of operative procedures, and their effects on prognosis are all studied.Results: Males were affected more than females (a ratio of 3.4: 1); birth weight has a significant association with the prognosis (P-value of 0.045). Hirschsprung`s disease was the commonest cause for perforation (29%), followed by necrotizing enterocolitis and jejunoileal atresia (16.1%, each). Idiopathic perforations constituted only 12.9%. Ileum was the commonest site of perforation (58.1%), followed by cecum (16.1%). Stoma creation was the commonest operative procedure performed. Other procedures like, primary anastomosis, and primary peritoneal drainage followed by laparotomy were also used. This study revealed high mortality rate (45.2%). Complications like sepsis, anastomotic leaks, or burst abdomen carried a high risk of death.Conclusions: High mortality rate is encountered, especially for necrotizing enterocolitis. In contrast to other study, Hirschsprung`s disease is the commonest cause of perforation rather than necrotizing enterocolitis. Radiology has a relatively good accuracy in the diagnosis of intestinal perforations, although some cases were discovered intra-operatively. In this series, prompt accurate treatment with stoma creation harbored the best prognostic results; furthermore no benefits obtained from primary peritoneal drainage.

Published: January 2023

Background: Chronic Tonsillitis outcomes from frequent attacks of acute Tonsillitis usually for six attacks or more per year for two successive years. Poor dental hygiene had been associated with oro- pharyngeal problems and causes both dental caries and Tonsillitis alike.Objective: To evaluate the relation between chronic Tonsillitis and severity of dental caries among 4-5 years old children.Patients and Methods: Random sample of children was selected in Hospital of Baghdad medical city Otolaryngologic department city. Fifty-four children aged 4- 5 years old were participated in this study divided into two group: 29 children with Chronic Tonsillitis (study group) and 25 children with intact tonsils (control group). The determination of Chronic Tonsillitis performed through a clinical and histopathological examination and Caries experience was recorded according to Mühlemann (d1-4 mfs) Index.Results: Bacteriologic samples from children dental plaque(29 infected and 25 healthy) were cultured quantitatively for aerobic condition; Data reported that the mean values of bacteria (Strep. mutans, Strep. pyogenes, Lactobacilus spp, Strep. mitis and Strept. salivarius) and dental caries (dmfs, decayed, missing d3 and d4) among children with Chronic Tonsillitis were higher than children with intact tonsils with statistically highly significant difference (P< 0.001). Moreover the relations between (d4) and Strep. mutans, Lactobacilus spp and Strep. mitis were highly significant in positive direction among study group (children with Chronic Tonsillitis), while it was not among control group (children with intact tonsils).Conclusion: There seems to be an association between dental caries and Chronic Tonsillitis in children aged 4-5 years old. And, it may be accepted that the infection to pass much more frequently from the teeth to the tonsils than in the opposite direction. So It is necessary to improve oral health condition through elective preventive dental programs among children to minimize any para-pharyngeal infections like Tonsillitis.

Access to, and a more sustainable use of, resources, cost saving potential, and a multitude of strategic benefits have been identified as attractive opportunities for small and medium-sized enterprises (SMEs) to engage in business-to-business (B2B) sharing with some frustration by governments, researchers and practitioners that so little actual B2B sharing can be observed in industry practice. It remains a strategic challenge for SMEs to manage the shift from resource ownership to sharing since that transition requires a permanent change in their business model. In light of the transformational nature of this qualitative research gap, an Action Research methodology has been developed and implemented in partnership with a selected sample of Swiss SMEs favourably inclined towards B2B sharing activities. While discussing how Action Research might bridge the research gap and develop tangible, empirically grounded management recommendations, this paper also contributes specific Action Research methodology for other cases of transformational nature which present an ever more frequent and common scenario in business management research.
Eine „Neue Amin-Lektüre“? Der ungleiche Tausch auf dem Weltmarkt und die Rolle des Nationalstaats im Werk von Samir Amin
Authors: Heinze Robert
Published: January 2023

Der Artikel unternimmt eine Relektüre des Werks von Samir Amin, indem er zwei aktuelle Forschungstrends verbindet: die „Wiederentdeckung“ der Dependenztheorie (und von Samir Amin) durch Teile der Wirtschafts- und anderer Sozialwissenschaften und die Neubewertungen der internationalen emanzipatorischen Projekte der „Dritten Welt“, wie Bandung und die Neue Internationale Weltwirtschaftsordnung. Dazu fokussiert er auf die Rolle, die die Nation in Amins Werk spielt und postuliert, dass eine Untersuchung dieses Problems uns helfen kann, eine antinationale Kritik zu entwickeln, die gleichzeitig erkennt, warum Nationen ein so wichtiger Hebel für marxistische Analysen aus dem globalen Süden waren. Amins Werk biete so den Schlüssel für eine neue, fundierte Kritik des nationalistischen Antiimperialismus.

Numerous advanced data processing and machine learning techniques for identifying epileptic seizures have been developed in the last two decades. Nonetheless, many of these solutions need massive data sets and intricate computations. Our approach transforms electroencephalogram (EEG) data into the time-frequency domain by utilizing a short-time fourier transform (STFT) and the spectrogram (t-f) images as the input stage of the deep learning model. Using EEG data, we have constructed a hybrid model comprising of a Deep Convolution Network (ResNet50) and a Long Short-Term Memory (LSTM) for predicting epileptic seizures. Spectrogram images are used to train the proposed hybrid model for feature extraction and classification. We analyzed the CHB-MIT scalp EEG dataset. For each preictal period of 5, 15, and 30 minutes, experiments are conducted to evaluate the performance of the proposed model. The experimental results indicate that the proposed model produced the optimum performance with a 5-minute preictal duration. We achieved an average accuracy of 94.5%, the average sensitivity of 93.7%, the f1-score of 0.9376, and the average false positive rate (FPR) of 0.055. Our proposed technique surpassed the random predictor and other current algorithms used for seizure prediction for all patients’ data in the dataset. One can use the effectiveness of our proposed model to help in the early diagnosis of epilepsy and provide early treatment.

We study boundary value problems for bounded uniform domains in [Formula: see text], [Formula: see text], with non-Lipschitz, and possibly fractal, boundaries. We prove Poincaré inequalities with uniform constants and trace terms for [Formula: see text]-domains contained in a fixed bounded Lipschitz domain. We introduce generalized Dirichlet, Neumann, and Robin problems for Poisson-type equations and prove the Mosco convergence of the associated energy functionals along sequences of suitably converging domains. This implies a stability result for weak solutions, the norm convergence of the associated resolvents, and the convergence of the corresponding eigenvalues and eigenfunctions. We provide compactness results for parametrized classes of admissible domains, energy functionals, and weak solutions. Using these results, we can then prove the existence of optimal shapes in these classes in the sense that they minimize the initially given energy functionals. For the Robin boundary problems, this result is new.

In this paper, we are interested in studying the well-posedness, optimal polynomial stability, and the lack of exponential stability for a class of thermoelastic system of Reissner–Mindlin–Timoshenko plates with structural damping, that is, with the dissipation of Kelvin–Voigt type on the equations for the rotation angles. We also consider the thermal effect with thermal variables described by Fourier’s law of heat conduction.
The influence of workforce diversity and job meaningfulness on employee engagement and organizational citizenship behaviors

BACKGROUND: This study was done after the COVID-19 pandemic that brough a lot of disruptions and changes in behaviors of employees. This study focused on behaviors of Z employees in the new normal environment after the COVID-19 pandemic. Generation Z presently form the biggest age group in Malaysia, accounting for 29% of the total population. They have their own way of behavior and working patterns that is different from previous generations. Despite the increasing number of Gen Z employees, there is a dearth of studies that examined the effect of workforce diversity and job meaningfulness on employee engagement and OCB after the COVID-19 pandemic. OBJECTIVE: This research aimed to find out the association between workforce diversity and job meaningfulness to employee engagement and Organization Citizenship Behavior (OCB) among Gen Z employees in Malaysia after the COVID-19 pandemic. This research also investigated the relationship between employee engagement and OCB. METHODS: This was a quantitative study, and a survey strategy was used to collect data from 160 respondents. SPSS and Smart-PLS were used to generate descriptive and inferential statistics. RESULTS: The results revealed that workforce diversity was the strongest predictor of employee engagement among Gen Z employees after the pandemic. Workforce diversity also had a significant impact on OCB. Comparatively, job meaningfulness had a significant impact only on employee engagement but there was also a significant impact of employee engagement on OCB. CONCLUSIONS: The study that was done after the pandemic is one of the first to examine the relationship between workforce diversity, job meaningfulness, employee engagement, and OCB and has extended the current literature through the focus on Generation Z employees. The results suggest that workforce diversity and job meaningfulness to be adopted by organizations to upgrade engagement of Gen Z employees after the COVID-19 pandemic. The increase in employee engagement post-COVID, will lead to lower employee turnover, improved productivity and motivation.
