Gestational weight gain in sub-Saharan Africa: Estimation based on pseudo-cohort design
Authors: Gebremedhin Samson , Bekele Tilahun
Published: May 2021

Background

Inadequate or excess gestational weight gain (GWG) leads to multiple undesirable birth outcomes. Yet, in sub-Saharan Africa (SSA) little is known about the weight gain pattern in pregnancy. The purpose of the study is to estimate the average gestational weight gain (GWG) in sub-Saharan Africa (SSA) and to examined whether there had been recent improvements or not.

Methods

Based on cross-sectional anthropometric data extracted from multiple Demographic and Health Surveys conducted in SSA, we estimated the average GWG in the region. Pseudo-cohort design was used to reconstruct GWG trajectories based on aggregated data of 110,482 women extracted from 30 recent surveys. Trend in GWG between 2000 and 2015 was determined using the data of 11 SSA countries. Pre-pregnancy weight was estimated based on the weight of non-pregnant women at risk of conception.

Results

On average, women in SSA gain inadequate weight (6.6 kg, 95% confidence interval, 6.0–7.2) over pregnancy. No meaningful gain was observed in the first trimester; whereas, women in the second and third trimesters put on 2.2 and 3.2 kg, respectively. The highest weight gain (10.5, 8.2–12.9 kg) was observed in Southern African sub-region and the lowest in Western Africa (5.8, 5.0–6.6 kg). The GWG among women who had secondary or above education (9.5, 8.2–10.9 kg) was higher than women with lower education (5.0, 4.3–5.8 kg). Likewise, GWG in women from richest households (9.0, 7.2–10.7 kg) was superior to those from poorest households (6.1, 5.3–7.0 kg). The estimated recent (2015–20) mean GWG (6.6, 5.8–7.4 kg) was not significantly different from what had been at beginning of the new millennium (6.7, 5.9–7.5 kg).

Conclusion

In SSA GWG is extremely low and is not showing improvements.

Background and Aim: Inappropriate overuse of antimicrobials might be associated with the spreading of antimicrobial-resistant bacteria in animal-based food products. Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli have been recognized as an emerging global problem in a One Health approach. This study aimed to assess the occurrence and antimicrobial-susceptible profiles of ESBL-producing E. coli among post-weaned calves and lactating cows in a parallel animal husbandry area.

Materials and Methods: Seventy-two pool fecal samples were collected from 36 smallholder dairy farms registered in Ban Hong Dairy Cooperatives, Lamphun Province, Thailand. Pre-enriched fecal samples were cultured in MacConkey agar supplemented with cefotaxime. The potential E. coli isolates were identified by not only biochemical tests but also polymerase chain reaction assay of the 16S rRNA gene. ESBL production was confirmed by the combination disk test. Antimicrobial susceptibility testing was performed by the Kirby–Bauer disk diffusion method.

Results: The occurrence of ESBL-producing E. coli at the farm level was 80.56%. The different phenotypic antibiogram of ESBL-producing E. coli was observed among post-weaned calf and lactating cow specimens. The most frequent resistance patterns of ESBL-producing isolates from both groups were amoxicillin-ceftiofur-cephalexin-cephalothin-cloxacillin-streptomycin-oxytetracycline-sulfamethoxazole/trimethoprim. For the median zone diameter, enrofloxacin-resistant isolates with narrow zone diameter values from lactating cow specimens were particularly more than post-weaned calf specimens (p<0.05).

Conclusion: These findings revealed the dynamic changes in ESBL-producing E. coli from calves and lactating cows in Lamphun Province, posing the inevitability to prevent bacterial transmission and optimize antimicrobial therapy in dairy farming.

Many manifold learning algorithms conduct an eigen vector analysis on a data-similarity matrix with a size of N×N, where N is the number of data points. Thus, the memory complexity of the analysis is no less than O(N2). We pres- ent in this article an incremental manifold
learning approach to handle large hyperspectral data sets for land use identification. In our method, the number of dimensions for the high-dimensional hyperspectral-image data set is obtained with the training data set. A local curvature varia- tion algorithm is utilized to sample a subset
of data points as landmarks. Then a manifold skeleton is identified based on the landmarks. Our method is validated on three AVIRIS hyperspectral data sets, outperforming the comparison algorithms with a k–nearest-neighbor classifier and achieving the second best performance with support
vector machine.
Researching Non-Conscious Dimensions of Architectural Experience
Authors: Weisen Marcus
Published: May 2021

Editorial Summary: Entitled »Researching Non-Conscious Dimensions of Architectural Experience«, Marcus Weisen's contribution explores the investigation of pre-reflexive ways of knowing, sensory thought, and the embodied mind. He introduces the micro-phenomenological interview as a successful methodology to exploit immanent, non-conscious aspects of architectural experience. He emphasizes the relevance of investigating the individual, subjective perspective in architectural research, proposing the first-person description of experience as a starting point from which to derive insights into overarching, essential principles of lived experiences of, and encounters with, architectural spaces. Tracing the elusive, embodied dimensions of architectural experience, he aims for an »embodied rationalism« in architectural research. [Uta Graff]
Architectural Drawings: Teaching and Understanding a Visual Discipline
Authors: Schmid Peter
Published: May 2021

Editorial Summary: Professional drawing has always played an important role in the training of architects. Plan-drawings have already been sufficiently considered in established architectural research. The research of Peter Schmid presented in this text focuses on so far only scarcely examined architectural sketchbooks as well as various records used for architectural education, such as manuscripts for lectures or notes on perspective theory which belong to the »Munich School« - a tradition of teaching hand-drawing that developed over a period of 150 years through an on-going teacher-student relationship at the Technical University of Munich. He finds that the aim of »Munich School« was not only learning how to illustrate, but also to comprehend architecture through graphic analysis - thereby combining teaching and practice. Against the background that the interest in hand-drawings has significantly increased in recent years, the research helps to refine the role of hand-drawings today as a tool that sets »processes of cognition in motion«.

Archives, Bureaucracies, Architecture: Now You See Me, Now You Don't
Authors: Meister Anna-Maria
Published: May 2021

Editorial Summary: In her text, Anna-Maria Meister focuses on the production and dissemination of norms, normed objects, standards, bureaucratic measures, and administrative processes as social desires in German modern architecture. She states that we must treat them as formal and political acts of »Gestaltung« and critically probe their ideological intent and human con- sequence since the regulations in place, the order imagined, or the systems constructed were as formative to what we now know as Modern Architecture, as aesthetics or so-called Avant-Garde architects. As a result, rules and codes are »aesthetic tools« rather than mere »bureaucratic impediments«. She claims that it is necessary to research beyond the beaten path to include those contents that are usually left by the wayside, thus revealing and constructing alternative archives and histories.

Published: May 2021

In vitro fermentation systems offer significant opportunity for deconvoluting complex metabolic dynamics within polymicrobial communities, particularly those associated with the human gut microbiome. In vitro gut models have broad experimental capacity allowing rapid evaluation of multiple parameters, generating knowledge to inform design of subsequent in vivo studies. Here, our method describes an in vitro fermentation test bed to provide a physiologically-relevant assessment of engineered probiotics circuit design functions. Typically, engineered probiotics are evaluated under pristine, monoor co-culture conditions and transitioned directly into animal or human studies, commonly resulting in a loss of desired function when introduced to complex gut communities. Our method encompasses a systematic workflow entailing fermentation, molecular and functional characterization, and statistical analyses to validate an engineered probiotic’s persistence, plasmid stability and reporter response. To demonstrate the workflow, simplified polymicrobial communities of human gut microbial commensals were utilized to investigate the probiotic Escherichia coli Nissle 1917 engineered to produce a fluorescent reporter protein. Commensals were assembled with increasing complexity to produce a mock community based on nutrient utilization. The method assesses engineered probiotic persistence in a competitive growth environment, reporter production and function, effect of engineering on organism growth and influence on commensal composition. The in vitro test bed represents a new element within the Design-Build-Test-Learn paradigm, providing physiologically-relevant feedback for circuit re-design and experimental validation for transition of engineered probiotics to higher fidelity animal or human studies.
Capturing Primary School Students’ Emotional Responses with a Sensor Wristband
Authors: Sasse Heide , Leuchter Miriam
Published: May 2021

The emotions experienced by primary school students have both positive and negative effects on learning processes. Thus, to better understand learning processes, research should consider emotions during class. Standard survey-based methods, such as self-reports, are limited in terms of capturing the detailed trajectories of primary school  children’s emotions, as their abilities of self-reporting are developing and still limited. Emotions can also be tracked by capturing emotional responses as they occur e.g. from physiological reaction measured with sensor wristbands. This technology generates an emotional responsestypology based on continuously captured physiological data, such as skin conductivity and skin temperature. However, such measurement methods need to be validated before being used.
The present study thus attempted to validate this instrument with primary school students. We used the BM Sensor Wristband technology, as its emotional response typology is based on the categorical emotion and homeostasis approach. In our research, we focus on the emotional responses that can be distinguished by the BM Typology and that can influence learning processes. These emotional responses are: “joy”, “curiosity”, “attention”, “fear”, “anger” and “passivity”.

Therefore, we induced emotional responses in primary school children through specifically developed audio-visual stimuli. Using logistic mixed effects modelling, we investigated the occurrence of opposing reactions. We observed that primary school children’s reactions to audio-visual stimuli could be differentiated. We conclude that primary school children’s emotional responses, such as “joy”, “curiosity”, “attention”, “fear”, “anger” and “passivity”, can be accurately measured by evaluating physiological data.

Published: May 2021

The increasing use of power electronics devices as well as the integration of renewable source-based microgrids (MG) has seriously affects the power quality (PQ) of the three-phase power system. Therefore, for the improvement of PQ, it is required to reduce the total harmonics distortion (THD) in the utility network. In this work, the improvement of PQ is discussed in a photovoltaic (PV) based MG integrated three-phase system using a three-level H-bridge (3LHB) multilevel inverter (MI). The MI is used for compensating the source current harmonics and reducing the THD by meeting the IEEE standard guidelines. Besides, the proposed model helps manage the reactive power with control of DC link bus voltage through the PV system. The proposed model is helpful not only in reducing the harmonics but also in providing additional active power to the load if any electrical disturbances occur on the grid side. The maximum power point tracking (MPPT) technique employed in PV is of an improved form of Perturb and Observe (P&O). Further, the reference current generation is derived using the direct current control (DCC) and indirect current control (ICC) techniques. The MG integrated MI is investigated in both DCC and ICC method using three different DC bus voltage controllers; proportional-integral (PI), fuzzy logic controller (FLC), and fuzzy sliding mode control (FSMC). The proposed microgrid integrated system is analyzed with the MATLAB/Simulink tool.
Greener approach to substitute chemical reduction clearing process for fabric dyed with Foron Blue E-BL 150, Foron Rubine RD-GFL and Foron Brilliant Yellow S-6GL using indigenous resources
Authors: Khalique Abdul , Ali Shaukat , Khera Rasheed Ahmad , Asgher Muhammad
Published: May 2021

Fabric dyed with disperse dyes followed a reduction clearing process (RCP)/chemical clearing process (CCP) to remove the unfixed dye from the fabric. In the clearing process, unfixed dyes and chemicals are discharged into streams. To combat this issue, an environment friendly approaches is explored that is a biological clearing using indigenous fungal strains of white-rot fungi (Pleurotus ostreatus and Ganoderma lucidum). In this context, fabrics dyed with three disperse dyes (Foron Blue E-BL 150, Foron Rubine RD-GFL and Foron Brilliant Yellow S-6GL) were considered. The fabric cleared with biological clearing process improved the quality of fabric versus chemically cleared fabric and among the tested strains, G. lucidum showed higher efficiency for color strength improvement. However, no significant difference in tensile and tear strength of all fabric samples was observed. The quality of effluents in clearing reduction process for three dyes was assessed and it was observed that water quality parameters including chemical oxygen demand (COD), total organic carbon (TOC), biological oxygen demand (BOD), total suspended solids (TSS), pH, dissolved oxygen (DO) and total dissolved solids (TDS) improved significantly and results revealed that the biological clearing approach can substitute chemical reduction clearing process for fabric dyed with dyes, which is greener and eco-friendly versus conventional processes to avoid unfixed dyes discharge in to water bodies.
The Potential Causes of Paraplegia after Coronary Artery Bypass Grafting: A Literature Review
Authors: Cheng Zeyi , Xu Jin , Guo Yingqiang
Published: May 2021

Paraplegia is an unpredictable neurologic complication after coronary artery bypass grafting (CABG) surgery. It is rare but fatal, and the mechanism still is unclear. We aimed to make a summary of the possible causes of paraplegia after CABG. Pubmed database was searched from January 1, 1978 to December 31, 2019, and 14 studies were finally included. Paraplegia after CABG is a multifactorial consequence, but spinal cord ischemia is the key pathological factor to postoperative paraplegia.

Published: May 2021

Purpose: To explore the effect of undergoing coronary artery bypass grafting on sexual quality of life as an integral part of patients’ health-related quality of life.
Methods: This cross-sectional study included 265 men ages 18 to 60 years (median age, 55) who underwent coronary artery bypass grafting 1 to 5 years before the study. Standardized questionnaires were implemented to evaluate participant pre- and postoperative sexual quality of life and the quality of counseling provided to patients.
Results: Among the patients, 77% were in a steady relationship. The general health score was 5.5 ± 2.8 (mean ± standard deviation) preoperatively and 6 ± 2.2 at follow-up (P = .01). No sexual counseling was given to 83% and 77% of the patients pre- and postoperatively, respectively. The mean sexual satisfaction score dropped from 6.5 ± 2.6 preoperatively to 4.7 ± 3 postoperatively (P < .001). The decline in sexual intercourse frequency and masturbation frequency was significant (P < .001 and P = .006, respectively). Linear regression analysis showed that general health status (P = .008), higher-quality counseling (P = .027), and preoperative sexual quality of life (P < .001) correlated positively with sexual quality of life, whereas sternal pain (P < .001), erectile dysfunction (P < .001), and fear of excessive cardiac burden (P < .001) correlated negatively.
Conclusions: Middle-aged men experience decreased sexual quality of life after coronary artery bypass grafting. Preoperative sexual quality of life, general health, and higher-quality counseling positively affect postoperative sexual quality of life, whereas sternal pain, fear, and erectile dysfunction play a negative role. Pre- and postoperative care guidelines should be improved. Further prospective large cohort studies for males and females are required.
Early and Midterm Results of Stent Endarterectomy for Left Anterior Descending Coronary Artery “Full Metal Jacket”
Authors: Soliman Rafik , Ohri Sunil , Hagag Mohamed , Rasekh Fouad
Published: May 2021

Objective: Modern coronary interventional practice can result in coronary vessels that are totally stented. The term “full metal jacket” has been coined to refer to vessels that have an overlapping stent in series along the whole length of the vessel. This poses a serious challenge to surgical revascularization, particularly when a left internal thoracic artery (LITA) to the left anterior descending (LAD) needs to be undertaken. We evaluated the early and midterm results of on-pump coronary artery bypass grafting (CABG) following “stent endarterectomy” for the LAD with LITA to LAD grafting.
Methods: During October 2017 to September 2020, 21 patients presented with multi-vessel disease and a totally occluded LAD with a stent full metal jacket. No distal target for LITA grafting was available, despite a viable myocardial territory. The LAD was endarterectomised, removing the column of totally occluded stents with the medial wall of the vessel, leaving the proximal stent in place to avoid competitive flow. Long length anastomosis was then undertaken with the LITA graft. Postoperatively, patients were followed up clinically and by coronary computed tomography (CT) angiography at 6- and 18-month intervals. All patients were discharged on a combination of aspirin and warfarin for three months and then aspirin and clopidogrel for the rest of the first year and then aspirin alone for life.
Results: Patients had a mean age of 58.07 ± 2.06 yr. Sixteen (76.2%) were males, 13 (61.9%) patients were diabetics, 18 (85.7%) were hypertensive, 15 (71.4%) were dyslipidemic, six (28.6%) were obese, 11 (52.4%) were smokers, and five (23.8%) had positive family history of ischemic heart disease (IHD). The number of grafts per patient ranged 3-5, with a mean cross-clamp time of 64.71± 8.84 min. There were no postoperative deaths nor MI clinically, by electrocardiogram (ECG) criteria nor by troponin or CK-MB. In-hospital complications included one (4.8%) patient who required re-exploration for bleeding, one (4.8%) developed a superficial wound, and three (14.3%) developed atrial fibrillation (AF), during their hospital stay. Mean hospital stay was 7.71±1.73 days. All patients completed the 6-month follow up showing patent LITA to LAD with coronary CT angiography. One patient was lost to follow up after six months; five patients are awaiting their 18-month CT angiography, while 15 (71.4%) patients have completed their 18-month CT angiography, and all have a patent LITA to LAD.
Conclusions: Stent endarterectomy for a totally occluded LAD with a full metal jacket and viable myocardial territory is a safe procedure with good early and midterm results. This technique should be considered in these difficult cases presenting for revascularisation when no other option is available.

Authors: Bordón Ojeda Marisa
Published: May 2021

Este trabajo tiene como objetivo constatar que existe una situación de desigualdad económica y social entre hogares liderados por mujeres y aquellos liderados por hombres en Costa Rica. Para ello se tendrán en cuenta las variables del tiempo que en ambos hogares dedican a las diferentes actividades y los ingresos que perciben los jefes y jefas de hogar, a partir de los datos de la muestra obtenidos en la Encuesta Nacional del Uso del Tiempo 2017. Para el análisis se utilizaron los datos promedio obtenidos en la encuesta para el colectivo de jefes y jefas de familia correspondientes a las variables de la dedicación a de su tiempo y los ingresos. Como resultado del análisis se verifican diferencias en el tiempo que los jefes y jefas dedican al trabajo no remunerado y al trabajo remunerado, así como diferencias en la remuneración que reciben por su actividad principal. Estas evidencias nos llevan a reflexionar sobre la necesidad de implementar políticas públicas que compensen la situación desigual que padecen los hogares liderados por mujeres.
Prevalencia de Nosema spp. (Microsporidia: Nosematidae) en abejas africanizadas en Atenas, Costa Rica: número de esporas y nivel de infección durante la época lluviosa
Authors: Moreno Eduardo , Calderón Rafael A. , Ramírez Marianyela , Van Veen Johan
Published: May 2021

The prevalence of the microsporidium Nosema spp. was studied during the rainy months from July to November 2017 in 10 Africanized honeybees colonies in Atenas-Alajuela, Costa Rica. In addition, the number of spores and the infection level were compared in group and individual samples of adult bees from the same colony. The apiary was sampled once a month. Approximately 100 forager bees per colony were collected, of which 30 were examined for Nosema spp. in group analysis and 30 individually at the Bee Pathology Lab-CINAT. According to the Cantwell method, the abdomens of 30 adult bees were cut and macerated together with 30 ml of distilled water for the group test. For the individual analysis, the same method was used, but each bee was examined separately. Nosema spores were identified under the cover slip using a light microscopy at 40x magnification and were counted with a hemocytometer. The infection level was determined for every colony. The microsporidium Nosema spp. were found in all apiary colonies at different levels, ranging from low to severe infection in both group and individual exams. In July, the highest number of Nosema spores were quantified, with an average of 20,360,000 ± 1,586,957 per bee in the group analysis, and 12,749,733 ± 867,232 per bee in the individual analysis. In the following months, a considerable decrease in the number of spores was observed, and the lowest amount was recorded in November, with an average of 4,375,000 ± 874,132 and 2,087,708 ± 398,895 spores per bee in the group and individual exam, respectively. When comparing the spore count and the infection level of Nosema spp. in group and individual samples, similar results were obtained. Furthermore, by correlating the number of spores, high proximity in the values was found, showing that, by both methods, a similar result is obtained concerning the infection level of the same colony.

Consequently, the purpose of this research lies in the structuring of an alternative epistemological interpretation route, based on the concept of Didactics of Social Studies.
Limitations on the protective action of MgSO4 for cellulose during kraft pulp oxygen delignification
Authors: Huang Hai , Hu Yuantao , Zhang Hui , Cao Shilin , Ma Xiaojuan
Published: May 2021

Magnesium sulfate (MgSO4) is the most widely used protector for alleviating the effects that metal ions have on cellulose degradation. However, the efficiency of MgSO4 is limited by the oxygen delignification conditions. This work discusses the factors influencing MgSO4 efficiency in terms of cellulose protection and delignification. The type and concentration of metal ions, delignification rate, additions order, and mixing degree of MgSO4 should affect the cellulose degradation during oxygen delignification in the presence of MgSO4. The most adverse effects on cellulose are observed with Mn2+ and Fe2+ ions followed by Cu2+ and Fe3+. MgSO4 addition can diminish such negative effects; however the protection becomes reduced in the presence of higher concentrations of metal ions. In addition, the optimum MgSO4 application level is closely dependent on the delignification rate and metal ions concentration. Adding MgSO4 is optional for pulps with trace metal ions at relatively low delignification levels, but it is essential for pulps with concentrated metal ions or when the oxygen delignification rate is relatively high. More simply, when the added MgSO4 is thoroughly mixed with the pulp before the addition of NaOH, it exhibits a prominent effect on cellulose protection.
Modifications of proteins of membrane-cytoskeleton complex and production of reactive oxygen species in erythrocytes cryopreserved with polyethylene glycol

Protein modifications in the membrane-cytoskeleton complex (MCC) of human erythrocytes, as well as changes in the intensity of reactive oxygen species (ROS) production upon cell cryopreservation with polyethylene glycol (PEG) were investigated. The protein profile of ghosts of erythrocytes frozen with PEG has common features with both the control and cells frozen without cryoprotectant. PEG makes it possible to restrict the structural rearrangements of the main MCC proteins under the effect of extreme factors and to restrain the amount of high molecular weight polypeptide complexes induced by the protein-cross-linking reagent diamide at the control level, in contrast to cells frozen without a cryoprotectant. However, changes related to the protein peroxiredoxin 2 in ghosts of erythrocytes cryopreserved with PEG are also attributed to cells frozen without a cryoprotectant that may be associated with the activation of oxidative processes. This is evidenced by a 10-fold increase in ROS formation in erythrocytes frozen under PEG protection. Thus, upon cryopreservation of erythrocytes with PEG, certain disorders in MCC proteins may be associated with increased formation of ROS, which may contribute to the disorganization of the structural components of MCC and disrupt the stability of cryopreserved cells under physiological conditions.
Deep foundations of happiness. Principal fundamentals of different types of understanding happiness

The choice of the article’s topic is conditioned by the necessity to develop happiness management (such as knowledge management, time management, etc.). With considerable attention to the definition of “happiness”, the analysis of recent publications reveals that it is crucial to understand the deep foundations of happiness, create a typology, reveal the basic principles of different types of understanding of happiness, which was chosen as the topic research. Theoretical approaches to the definition of “happiness” are chosen sociology of imagination of G. Durand, the theory of archetypes of C. Jung, and the theory of images and dreams of G. Bachelard. In the context of this system of views, the idea of happiness is the result of a free play of the imagination, which, while being on the path from past to future, is transformed, revealed, comes accurate as a result of previous collective and individual intermediate ideas, and is enriched and concretised by individual people, social groups, individuals. The mythos of happiness across nations and people differs in the way, method, and tools of individuation, the discovery of the Self. The anthropological tract of happiness has an end to its existence. It is determined by the cessation of existence, the life of nations and individuals. The desire to experience pleasure (according to Freud), the desire to rise (according to Durand) are reflexive, which determines the physiological basis of happiness. Representations of happiness determine priorities, coordinate the direction of thinking, actions, reactions to external circumstances, and choose ways to achieve happiness. This is done through the transcendental function (according to Jung) – a psychological function that arises from the connection of the content of the unconscious with the content of consciousness. Achieving happiness allows one to strengthen the subjectivity and reveal their uniqueness, which allows them to identify typological features (archetypes) of behavioural reactions of people based on individual and group ideas about happiness. The authors reveal the basic foundations of such archetypes of happiness as hedonism, eudemonia, “rat racing”, nihilism, subjective well-being.

Paper dwells upon the theoretical and methodological foundations of leadership, considering key approaches and archetypal theories in modern value changes. The author notes the basis of the classical typology of leadership by M. Weber as manifestations of prereflective, emotional and rationalized trust in the leader. The typological foundations of archetypal leadership patterns based on dominant charisma, context and basic needs are identified. The possibilities of applying the basic ideas of the sociology of the depths of G. Durand in modern concepts of leadership are revealed, drawing attention to the problems of interpreting gender archetypes and their synergistic effects as stabilizing attractors. The main provisions of the philosophy of G. Durand are investigated, emphasizing the possibility of overcoming the logocentric worldview prevailing in Western culture and opening the horizons of visualizing living semantic complexes of archetypes and myths. These categories are proposed to be considered as the primary cognitive and emotional assets of leadership to substantiate the sources of the innovative and self-realization potential of modern leaders. The article analyses the peculiarities of applying mythoanalysis in political leadership, which is undergoing modifications under the diurnal and nocturne regimes in heroic, dramatic and mystical narratives. Paper investigates the features of the mythocritical and mythoanalytic method of G. Durand. It is noted that mythoanalysis expands the mythological narrative to the socio-cultural context of an epoch, country, period, universal social practices, building an ideal myth-model even outside of historical time in the eternal return of myth. The conceptual reformatting of the archetypes of gender leadership discourse in the communicative foundations of moral influence is considered. The communicative aspects of leadership in masculine and feminine motives of hunting and caring archetypes are determined.

The article is devoted to the matter of the interconnection of social services and the image of their recipients. Among the latter, special attention is paid by scientists and practitioners to elderly people in an ageing population. The authors promote awareness of the importance of the social work principles with the elderly and its compliance with spectrum, level, and hierarchy of their social needs. The range of needs of the elderly people, which are met through social services, is constantly expanding; conditions and approaches to their typology and satisfaction are also changing. The authors offered to consider the image of the elderly people in a deeper sociological dimension: through the views of experts in social work about this group of social service recipients. During the expert survey, conducted by the authors among specialists of the territorial centres of social services for the city of Kharkiv and Kharkiv region inhabitants, it was revealed that the image of the elderly people is fixed through the emotional perception; the idea of what is missing for the elderly people (their needs that are not satisfied); associations that appear towards them as a problem group. Elderly people at the social work professionals’ emotional level (regardless of their gender, age, signs, educational potential, accommodation) bring out mostly positive emotions, setting them up to perform their professional duties. Differences in the views of experts on the needs of elderly people are due mainly to a spatial factor – a place of residence. It is shown that the views of social work specialists about the image of their clients are formed based on the acquired in the process of professional activity, specific sensory impressions about the elderly. The authors determined the requirements for the views of social work specialists about the elderly. The latter must correspond to the triad: to be creative, critical and productive. The creative imagination of social work specialists is in demand, which involves their independent creation of new images of the elderly people as recipients of social services depending on the specific time, life situation and personal strategies of social participation/social exclusion of the elderly.

This article explores trends in language policies in the Transcarpathian region during 1991–2020 within the general Ukrainian sociopolitical context. It is argued that the status of the Ukrainian language as the state language in the region has become strengthened as evidenced by recent developments in language planning and language policy, including the adoption of the Law “On Ensuring the Functioning of the Ukrainian Lan-guage as the Official Language”. However, the manipulation of the language question in Ukraine, especially in the border regions, has taken on a political character, spreading beyond the borders of the state, threatening the constitutional order and the state sovereignty of Ukraine, in particu-lar in education, economics, and legal sphere. In Transcarpathia, a multi-ethnic border region in the extreme west of Ukraine, warrants attention of both scholars and politicians. This article looks into the changes in the Ukrainian language policies in the local state administration, and the importance of the Ukrainian president office in this regard. Specific features of the linguo-political situation in Transcarpathia, viewed at different periods of its development from the independence of Ukraine in 1991 on-ward, are presented. This study determines the role of the media in shaping a regional linguo-political situation, including the Internet media language space. The paper provides data of a comprehensive analy-sis of the results of the 2017–2019 external independent evaluation as an indicator of language competence of the participants of EIE, the results of research on the perception of educational language innovations in the region through a survey of different categories of respondents during 2018, the monitoring of experimental experience in implementing elements of multilingual edu-cation in educational institutions in Ukraine, particularly in Transcarpathia. The author outlines prospects for continued research in the framework of the project “Debat ing Linguistic Diversity: Managing National Minority Languages in Ukraine and Russia” (2020–2023). Keywords: language policy, language situation, state language, mother tongue, minority language, multilingual education, mass media.

This article looks into the linguistic mechanisms designed to establish communication between the presidential candidate Volodymyr Zelens’kyi and the youth in the 2019 Ukrainian election campaign. The young voters, who are less familiar with the political, economic, and social processes in the country due to their age and little life experience are at risk of falling victim to political technologists. The article examines Zelens’kyi’s political projects on Facebook, Instagram, YouTube, Tele-gram, and Viber channels, the Twitter page of his campaign stuff, and the personal Facebook page. Aside from technological techniques, the paper focuses on the discourse of the election campaign built by the technologists to win the favor of young voters. It examines a linguistic component of the election rhetoric of this particular political project and reconstructs the main messages addressed to the youth. A complex of special linguistic methods has been applied to the texts,e.g., content analysis, discourse analysis, and critical discourse analysis, which helps “to deci-pher” the ideological components. Successfully selected channels, practices, and methods of virtual communication, “cor-rect” messages, and manipulative methods of the language use of the election campaign waged by Zelens’kyi, e.g., the clash of two generations theme, were converted into the votes “in favour” for the previously inactive electoral group. Convergence tactics were used to adjust the language to the younger generation. These in-clude the use of vocabulary from the Internet and the latest technologies, borrowings, informal youth forms of address, slang forms, language games, graphic capabilities of electronic space, in particular hashtags, stickers, and emojis. Keywords: communication, social networking, targeting, Facebook, vulgarisms, slang.
The active dictionary of lexical combinatorics as a means of optimizing language learning
Authors:   Institute of the Ukrainian Language of National Academy of Sciences of Ukraine, Trub Volodymyr
Published: May 2021

An important element of language competence is the knowledge of different features of lexical combinatorics. This article describes the structure of an Active Russian-Ukrainian Combinatory Dictionary of Nouns. The main goal of the Dictionary lies within the systematic representation of lexical combinatorics of a particular entry keyword along with its translation equivalent. A keyword is a Russian noun which designates such situations as an action, activity, process, pro-perty, state, or an event. Each lexeme which denotes a situation usually relates to a number of other lexemes that denote correlation between the participants of a situation, its variable signs, typical impacts, e.g., beginning or terminating a particular situation, its creation or ending, and other impacts constrained by its specifics. It is essential that different names of situations relate to different sets of lexemes attached to them. A combination of words with the name of a situa-tion and a lexeme that this name relates to is called collocation. In corpus linguistics, colloca-tions are described by means of apparatus of lexical functions (LF). Thus, the accompanying lexeme of the word combination conveys the meaning of LF for which the name of situation serves as an argument. In the Dictionary, eасh entry involves not only a Russian noun naming situation and its Ukrainian translation but also a set of collocations that correlate with the noun. Each Russian collocation is accompanied by its Ukrainian equivalent. The use of such a dic-tionary furthers the knowledge of the user’s native (first) language (Russian or Ukrainian). The Dictionary is especially important for learners of Ukrainian as a second language. It contains information about “paradigmatic syntagmatics” in Ukrainian yet not fully represented in bilin-gual dictionaries. Keywords: dictionary, noun, combinatorics, collocation, lexical function, predicate, actant.
Interrogative statement and discourse-stylistic continuum of the Ukrainian language

Interrogative statements are used to perform the intention of the query in various discourse-stylistic forms of the Ukrainian language. This article aims to analyze interrogative statements from the stand-point of their functioning as syntactic constructions. Drawing on a wide range of literary sources, the author states that, fulfilling the epistemological need to fill information gaps in speaker’s knowledge, the interrogative statement is the most relevant linguistic sign used to express the speaker’s motivation and needs. The interrogative statement is, however, a clear example of communicative-pragmatic functions which include figurativeness, expression of will, emotionality, evaluation, and tolerance, verbalized in a speech in accordance with the speaker’s intentions. A suggested in terpretation of the linguistic nature of interrogative constructions attests to their ambivalence and semantic syncretism along with the performance of primary and secondary functions. The discourse-stylistic continuum of the Ukrainian language, i.e., vernacular, literary, journalistic, religious, and epistolary, represents a rather extensive functional potential of inter-rogative constructions. In spoken discourse, interrogative expressions, e.g., address-oriented syntactic units, verbalize the specifying and clarifying intentions of the query, thus highlighting their primary function in the dialogic discourse. In other registers, these are secondary func-tions related to the following aspects: 1) figurativeness and aesthetics of speech which em phasizes the linguo-creative nature of a speaker, i.e., fiction; 2) the display of certain information which has a purposeful influence on the addressee of the speech and encourages specific actions, i.e., journalistic discourse; 3) the creation of aphoristic and rhetorical dialogue, establishing spiritual values and a human worldview, i.e., religious discourse; 4) the creation of epistolary dialogue as a marker of the interrogative searching process focused on essential phenomena related to pub-lic and private life and aimed at the formation of textual communication conceived in time and space. This article introduces the concept of interrogative discourse as a dynamic continuum of human communication, a special mode of cognition and reflection of reality, one of the latest fragments of linguistic knowledge. Keywords: interrogative statement, discourse-stylistic continuum, the intention of inquiry, address-ability, dialogicality / quasi-dialogicality, interrogative discourse.
Carbon-nitrogen ratio in soils with fertilizer applications and nutrient absorption in banana (Musa spp.) cv. Williams
Authors: Pérez Wilson Antonio , Torres-Bazurto Jaime
Published: May 2021

This research took place in Uraba, Antioquia, in the CENIBANANO-AUGURA experimental field, where a research program on nutrition and fertilization in bananas is carried out. This crop requires high amounts of nitrogen for production, so it is indispensable to evaluate the impact of these applications on the carbon-nitrogen ratio (C/N ratio) in soil. Published literature is scarce for this problem. This research evaluated the C/N ratio in areas with fertilizer applications and nutrient uptake, along with the interaction with production in a banana crop of the AAA group giant Cavendish subgroup, Williams clone, sixth generation in two production cycles. A randomized complete block design was used with five treatments that consisted of differential doses of nitrogen (161, 321.8, and 483 kg ha-1), and an omission and absolute control distributed in four replicates. The treatments with nitrogen doses generated statistical differences for the interactions between the two study zones for the percentages of carbon and total soil nitrogen and C/N ratios; the highest values were found in the fertilization zone during the first production cycle (2.47% C, 0.33% N, and 7.7 C/N ratio). The treatment with 483 kg ha-1 of N obtained the greatest increases in the values for these variables that are attributed to the highest dose of nitrogen and the residual acidity of urea that was able to release non-free carbon from the soil. For this reason, the correlation analysis for the C/N ratio and production was significant for the study areas (absorption and fertilization), inferring that higher C/N ratio values tend to increase production.
