Field research: Problem, tasks, opportunities. Part 1
Authors:   Institute of Psychology RAS, Tolochek Vladimir A.
Published: April 2024

For more than a century, the state of psychology has been characterized as a crisis (crisis of methodology). The present state of the social objects, which serve as the research subjects for us, is characterized by increasing dynamism and variability. The current state, as reflected in its typical objects and conditions of conducting scientific research and practice work by ordinary researchers, often remains out of the attention span of methodologists and historians of science. Changes of the conditions created for conducting scientific research and research and practice work in modern institutions require reinterpreting the methods and methodology of the discipline and of the third-level disciplinary methodology. These are conventionally called by us “methods and methodology of field research”. The raised issue is masked and smoothed out by the dominance in Russian psychology of researches based on models of academic groups (schoolchildren, students, seminar listeners, etc.), i.e., by scientific research and research and practice works conducted under relatively simple conditions. However, the range of research and practical tasks is much wider; a pronounced shift to studies of mainly academic groups is a shift to “accessibility and comfort” zone and it leads to the erosion of the discipline. Purpose: historical and theoretical analysis of methodological, methodical and organizational aspects of conducting the research in a modern institution. Methods: analysis of scientific literature, psychodiagnostics, reflection on the experience of scientific research and practical work in modern institutions. It is summarized that: 1) the state of the discipline methodology, understanding of its method, subject and technology of conducting relevant scientific research, and explanation of the results obtained are interrelated; 2) with the availability of administrative resources methodological and methodical problems persist and are reproduced even under strictly specified diagnostic conditions; 3) diagnostic issues in the space-time dimension of modern institutions change the unresolved tasks of “methods and methodology of field research” into the status of “raised to the second power problems, “raised to the third power problems”; 4) one of the least developed issues of psychodiagnostics is the issue of the “situation”, which requires its constructive solution.

Authors:   Saratov State University, Ryaguzova Elena V.
Published: April 2024

The relevance of the research is due to the fact that in the modern technogenic world, kindness requires special attention because of several reasons: first, kindness is a gift that contributes to the preservation of the humane in a human; second, it resists the devaluation and depersonalization of human individuality; third, it unites people on the basis of deep spiritual values; and finally, kindness helps people develop and improve themselves through the expansion of social ties and activation of prosocial behaviors. The objective of the research is to identify how kindness in interpersonal relationships is specific to a person depending on its dominant mode. Hypothesis: the subjective experience of receiving and showing kindness in interpersonal interactions determines its content and the specifics of verbal referents. Participants: students (N = 75) of Saratov State University (Saratov) aged between 20 and 22 years (M=21.48; SD=1.12), 83% female. Methods (tools): prototypical methodology for describing the structure of the social concept of kindness (P. Verges); semantic differential technique to characterize the semantic space of the construct “kind person” (Ch. Osgood); methodology of kindness modes to determine its dominant mode (D. E. Youngs, M. A. Yaneva & D. V. Canter); self-actualization test for the diagnosis of the self-actualization index (E. Shostrom adapted by A. Jones, R. Crandall); behavioral activity questionnaire to determine its type (L. I. Wasserman and N. V. Gumenyuk). Results: the research reveals the structure of the social concept of kindness, constructs the semantic space of the concept “kind person”, identifies the three groups that differ in relation to themselves and Others, in relation to the modes of kindness, ideas of kindness, behavioral patterns and the specifics of verbal referents. Conclusions. The research has worked out the invariant meaning of the concept of good and kindness in different languages; the study has emphasized intersubjective (caring for the Other) and intrasubjective (caring for oneself) psychological orientations of kindness, which are associated with the responsibility of the individual for the present and future of their own and of the Other’s; the research has identified the tendency to understand kindness one-sidedly reducing it to a helping behavior and identifying it with the proper care of the Other; the study has established that the subjective experience of receiving and showing kindness in interpersonal interactions determines the type of the kindness mode and the specifics of verbal referents. Practical significance. The results of the study can be used in counseling and psychological training.

Authors:   Krasnodar Higher Military awarded by the Order of Zhukov and by the Orders of October Revolution and the Red Banner School named after the general of the Army S. M. Shtemenko, Avakyan Inna B.
Published: April 2024

The relevance of the research is due to the need to implement the principle of cooperation and interaction of the subjects of the educational process, and to use the creative approach in the situation of modernizing higher education. The purpose of the research is to identify indicators, criteria, and development factors of university teachers’ pedagogical conservatism. The study hypothesizes that the state of pedagogical conservatism among teachers of higher educational institutions: 1) may be correlated with the level of integral satisfaction with professional activity; 2) indicates the presence of factors contributing to its development. The study participants: the teaching staff of 9 Russian universities (N = 1754, aged from 25 to 65, including 25% of men, 75% of women). The research methods (tools): methodology "Assessment of pedagogical conservatism of teachers of a higher educational institution" (I. B. Avakyan) was used in order to study indicators and criteria of pedagogical conservatism, as well as to identify its development factors, integral job satisfaction test (by A. V. Batarshev) was used to assess the integral indicators of satisfaction of university teachers with their pedagogical activity. Results. The study has revealed the development factors of university teachers’ pedagogical conservatism. These factors comprise psychological unpreparedness for innovative activity, including a set of variables that are presented in the study, and emotional burnout. A positive correlation has been found between a group of indicators of pedagogical conservatism and components of integral satisfaction with pedagogical work (habitual ways of performing the activity and general satisfaction with work). The study has also revealed the inverse (negative) correlation between the other group of pedagogical conservatism indicators and satisfaction with pedagogical activity (low motivation for success and overall job satisfaction). The main conclusions. On the one hand, indicators of pedagogical conservatism contribute to the increase in the level of satisfaction with pedagogical activity, which ensures the preservation of pedagogical experience in conditions of internal psychological balance. On the other hand, they contribute to dissatisfaction with their own activities and to the state of professional stagnation. The obtained results can be used as the basis for systematic psychological and pedagogical support of the university teachers’ professional activities in accordance with educational stan dards.

Fintech Solutions for West African SMEs: Post-Crisis Challenges
Authors: Boubacar Emine Dahi, Mohamed
Published: April 2024

Catalysts of economic growth worldwide, small and medium enterprises (SMEs) play a pivotal role in fostering job creation, social advancement, and innovation. In Africa, they account for 95% of job providers (World Trade Organization, 2022). Yet, SMEs often face significant hurdles, with limited access to finance being chief among them, especially in the aftermath of financial crises. Traditional banks, hampered by regulatory changes, have scaled back lending to SMEs, paving the way for Financial Technology (Fintech) firms to offer innovative financing solutions. Utilizing cutting-edge technology and varied business models, Fintech platforms provide SMEs with alternative financing options, including debt and equity financing. This disruption in the financial landscape holds promise for SMEs, liberating them from reliance on traditional banking channels and providing crucial capital for growth and expansion. SMEs can significantly contribute to achieving Sustainable Development Goals (SDGs), such as creating employment, reducing income inequality, and alleviating poverty (OECD, 2017).

The post-crisis era has not only hindered traditional financing avenues but also birthed new alternatives. These non-bank financing options empower SMEs by presenting fresh funding opportunities. While Fintech companies are thriving in developed nations, many developing countries are lagging. Despite the numerous benefits Fintech financing offers to SMEs, certain countries are slow to adopt them, hindering progress
Reference materials: A review
Authors: Outaki Meriem , Loukhmas Sarah , Gmouh Said , Kerak Ebrahim
Published: April 2024

Several factors have increased the use of reference materials in laboratories. This can be explained by the fact that the reference materials have several roles, namely: the confirmation of the identity of unknown materials and/or the determination of their properties; the calibration of measuring equipment; the validation of methods; the realization of proficiency tests; etc. To be able to produce and use them, a set of standards and guidelines concerning the subject of reference materials has been established. There are several producers of reference materials in many fields, but finding the right choice is sometimes considered difficult given the multitude of materials to be analyzed that do not correspond perfectly to the reference material, especially in the case of matrices. This makes the market always seek new materials. To develop them, five steps are essential: material preparation, homogeneity study, stability study, characterization, and evaluation of measurement uncertainties. These steps are equally important; the fact of highlighting less than one of them will imply a significant decrease in the quality of the reference material developed. This review seeks to furnish the scientific community with a paper elucidating the functions of these materials in research laboratories, the normative references devised to standardize their production and utilization, the factors influencing their production, and the essential steps for their development.

BLUP Estimation and Genotype Stability in Arachis hypogaea L. Variety Testing using Mixed Model Equations
Authors: Barsalia Ramandeep Kaur , Brar Khushwinder Singh , Singh Pritpal , Sandhu Surinder
Published: April 2024

Background: One of the major goals of plant breeding is the selection of high yielding superior cultivars having wide or specific adaptation. However, there is a fluctuation in the annual production due to the sensitive behaviour of the genotypes under different environmental conditions referred to as Genotype by Environment Interaction (GEI). The current study aimed to study the contribution of GEI for the adaptation of groundnut lines for spring and/or kharif season. Methods: To assess the contribution of GEI, Multi-Environment Trials (METs) were conducted for 40 confectionery purpose groundnut genotypes at F9 generation along with checks, across three locations for two seasons (spring and kharif). The contribution of environmental effects, genotypic values and genotype × environment interaction values were obtained from genotypic variance-covariance matrix Gi = Σg⨂A using mixed models (MM) in Best linear unbiased predictions (BLUPs).The pooled data was first partitioned into fixed effects of sites across the seasons and BLUP genotypic values (Ggge). The BLUP genotypic values are further partitioned into genetic value (Gg) and their interaction with the environment (Gge) for the adaptability of genotypes across seasons. Result: The results of MET revealed the presence of significant crossover interaction. The demarcation of advance breeding lines for adaptability across the environment as well as for season specific adaptation was done for variety testing. Genotypes having moderate to high Gge values along with high Gg values in spring than kharif, owing to their better performance during the spring season. CGL-11, CGL-23 and CGL-04 were the highest yielding genotypes, with quite high Gge values. This is due to the more favourable environmental conditions interacting positively with genotypes during the spring. Thus, the high Gg value(s) of genotype(s) alone is not a capable factor for commercialization as Gge value is the deciding factor for the adaptability for the targeted season.

Background: The development of new protocols has become a priority today in the context of the adverse effects of conventional treatments. Zeolite falls into this category due to its numerous applications reported in the specialized literature. In this study, the main expected objectives were to demonstrate that intrauterine administration of zeolite can contribute to improving the indicators underlying the development of pathologies during the postpartum period. Methods: To determine the dosage and potential toxic effects on the uterine mucosa, we conducted a study on rats, to which we administered different doses on the second day after delivery. Ultrasound measurements of the uterus, collection of bacteriological samples and uterine tissue were performed at 7, 14 and 21 days. The results were satisfactory in terms of tissue effects, with the 20% dosage being the most suitable. Following the completion of the preliminary study, we grouped the animals into two equal groups (n=32). Intrauterine administration of zeolite was performed on the second day after delivery and monitoring of uterine involution was carried out on days 7, 14 and 21 of the puerperium. At 14 days, we collected samples to determine the number of bacteria and uterine tissue. Result: The data obtained indicate that the group receiving intrauterine zeolite (n=16) experienced a decrease in the number of bacteria, significantly faster uterine involution on days 14 and 28, a more favourable uterine score and a significantly shorter service period. However, no significance was established regarding the number of doses of seminal material used.

Published: April 2024

Background: Breast cancer is a prevalent global health concern. Traditional medicine often incorporates the use of medicinal plants to address various diseases. Methods: The cytotoxicity, oxidative stress and cell migration effects of saponin and phenol extracts were evaluated through MTT assay, ROS analysis and wound-healing assay. Following the identification of the active extract, it underwent GC-MS analysis and in silico investigations. Result: Our results revealed significant inhibition of cell proliferation in MDA-MB-231 (IC50:407.3 μg/mL) and HUVECs (IC50:500 μg/mL), which was achieved only with the ethyl acetate extract (Fraction 2). Fraction 2 extract induced notable morphological changes and significantly inhibited time-dependent migration in MDA-MB-231 cells. Additionally, it elevated cellular ROS levels compared to the control cells. In molecular docking analysis, out of the 51 chosen secondary metabolites from L. shawii, stigmast-5-en-3-ol, (3α,24S) (-10.0 kcal/mol) and lup-20(29)-ene-3,28-diol (-9.5 kcal/mol) were found to be the best docked to their respective targets-6CHZ and 4MAN, respectively. Therefore, this plant holds promise as a potential therapeutic agent for breast cancer treatment.

Authors: Özkök A.O.
Published: April 2024

Background: Canaries have attracted people’s attention with their colors, shapes and impressive songs. The fact that canaries are domesticated and easy to obtain has made these birds attractive for songbird studies. In our study, canary semen was examined at different temperature values. This study aims to determine the most efficient spermatozoa examination temperature in canaries. Methods: In this study, five different temperature values (36, 38, 40, 42 and 44°C) were determined. The study used 6 active male Gloster canaries in each group. After each semen collection application, a 3-day break was given for the birds to rest. Dulbecco’s Modified Eagle Medium (DMEM) expander, which is preferred by songbirds, was used in the research. The semen was diluted 1:2 in a water bath at specified temperatures (36, 38, 40, 42, 44°C) and immediately examined for motility and viability. Result: When the study results were evaluated, it was seen that the viability rate at 38°C was higher than the other groups and 40°C gave the highest results in terms of motility. In addition to the viability rate at 38°C, the swimming speed of spermatozoa was also found to be more stable over a wider area than other groups. As a result, based on the data obtained from the study, it can be said that the most appropriate temperature for motility and viability in canary spermatozoa is 38°C.

Authors: Kumar Anil , Sharma N.K. , Kumar Ravindra , Sanadya Sanjay Kumar , Sahoo Smrutishree
Published: April 2024

Background: Mungbean is an important grain legume crop. It contains a high amount of protein, carbohydrates, vitamins and minerals. The productivity of this crop is still low, hence efforts should be made to improve the yield of mungbean by keeping knowledge about association between seed yield and its components. Thus, the present investigation was aimed to determine the correlation and path coefficient analysis for seed yield and its attributing traits in mungbean. Methods: Seventy-nine diverse genotypes of mungbean were evaluated during Kharif 2017-18 for eleven quantitative traits in randomized block design with three replications at the Experimental farm, Department of Genetics and Plant Breeding, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner, Rajasthan. Result: Significant genotypic differences were observed for all the traits studied indicating a considerable amount of variation among genotypes for all the characters. The seed yield per plant exhibited highly significant and positive correlation with number of pods per plant, biological yield per plant, harvest index, number of seeds per pod and pod length. The characteristics such as biological yield per plant, harvest index, number of pods per plant, pod length, number of seeds per pod, plant height, 100-seed weight and days to 50 per cent flowering had high positive direct effect on seed yield per plant. Therefore, selection based on the traits viz., number of pods per plant, biological yield per plant, harvest index, number of seeds per pod, 100-seed weight and pod length could help in enhancing the seed yield per plant in mungbean.

Published: April 2024

Objective: study of the influence of a number of operational factors on the final resistance of varitropic concrete to alternating cycles of wetting and drying. This work identifies the problem of concrete resistance to cyclic wetting and drying, and also formulates a scientific deficiency consisting in the inadequacy of the existing knowledge base regarding the relationship between the type of concrete structure and its resistance to cyclic influences, including alternating wetting and drying. Methods: test samples were made using three different technologies: vibration, centrifugation, and vibration centrifugation. The following main characteristics were studied: compressive strength, tensile strength in bending, water resistance. Experimental studies have shown that concretes with a varitropic structure (centrifugation and vibration centrifugation) have higher resistance to alternating wetting and drying than concretes with an anisotropic structure (vibration). After 500 cycles of wetting-drying and a high degree of aggressiveness of the saturated aqueous environment in terms of the content of sulfate, chloride and nitrate salts, the loss of compressive and tensile strength in bending for vibrated concrete was 28.7 and 32.7 respectively, for centrifuged concrete — 26.2 and 27.8%, respectively, and for vibrocentrifuged ones — 19.6 and 21.4 %, respectively. Results: Vibrocentrifuged varitropic concretes showed the greatest resistance to the effects of alternating wetting in an aqueous environment with varying degrees of aggressiveness and drying compared to centrifuged varitropic and vibrated anisotropic concretes.

Published: April 2024

Saving water of better quality for more important uses is critical in the context of preventing water scarcity. Prominent in this sense is the need to study not only the technical aspects involving environmentally conscious consumption, but also the acceptance of users, since appropriate technologies are of little value if they are not assimilated. Therefore, this work aimed to evaluate how well users accepted interlocking concrete paving blocks produced with treated wastewater rather than drinking water. To this end, questionnaires were administered to members of the faculty, student body and staff of a school of civil engineering, architecture and urban design in the city of Campinas (SP/Brazil), resulting in 238 answers. It was found that 79% of participants identified no visual differences between conventional paving blocks and those produced with treated wastewater, and that 96.6% were willing to use such blocks in outdoor areas of future construction work. On the other hand, there was a reduction in the acceptance of the paving blocks for use in indoor areas and the respondents’ own homes. Hence, even though its results were largely positive, this survey raised a few points of attention regarding the acceptance of the technology in question.

Authors: Yetik Ali Kaan , Candoğan Burak Nazmi
Published: April 2024

Understanding the dynamics of precipitation patterns is crucial for effective water management strategies, especially in regions vulnerable to the impacts of climate change. This study investigates the projected changes in annual and seasonal precipitation across the Southern Marmara Region of Turkey by comparing the averages of the reference period (1971-2000) with those of the future period (2061-2090). Employing multiple climate models (GFDL, HADGEM, and MPI) and Representative Concentration Pathways (RCP4.5 and RCP8.5), the analysis includes Mann-Kendall trend tests and Sen's slope method to determine trends in precipitation patterns. Key findings reveal significant variability in precipitation projections among different models and scenarios, with implications for water resource management, agriculture, and ecosystem resilience in provinces such as Çanakkale, Balıkesir, Bursa, Bilecik, and Yalova. According to the annual rainfall change rates relative to the reference period, Balıkesir province stands out as the most resilient province against climate change with average rates of 8.81% and 7.09% under the HADGEM and MPI model simulations, respectively. Regarding seasonal variations, Bilecik province is expected to experience a significant decrease in rainfall, reaching up to -53.78% under the MPI RCP8.5 scenario. In terms of within-period changes in annual rainfall values, the strongest declining trend was identified with Z=-2.03 in Bilecik province under the MPI RCP8.5 scenario conditions by the Mann-Kendall test. On the other hand, for seasonal variations, Bursa province demonstrates the most robust decreasing trend under the GFDL RCP4.5 conditions (Z=-2.89). The study emphasizes the importance of considering spatially varying precipitation patterns and potential shifts in atmospheric circulation for sustainable water resource management amidst climate variability and change in the Southern Marmara region. These findings provide critical insights for policymakers and stakeholders involved in developing adaptive strategies to address the challenges posed by future climate scenarios.

In this study, the friction factor of turbulent pipe flow for dried rice malt extract solutions is reduced experimentally to that of a Newtonian fluid. The friction factor is measured for four types of solutions at different culture times and concentrations. The results indicate that the experimental data points of the test solutions diverge from the maximum drag reduction asymptote at and above Re√f ≅ 200 and align parallel to those of Newtonian fluids. This drag reduction phenomenon differs from that of artificial high molecular polymer solutions. It is classified as a Type B drag reduction phenomenon of biopolymer solutions and fine solid particle suspensions. The order of drag reduction corresponds approximately to that of 5–50 ppm xanthan-gum solutions reported previously. Furthermore, the velocity profile in a turbulent pipe flow was predicted using a semi-theoretical equation, in which the friction factors were determined using the difference between the experimental results of the tested solutions and Newtonian fluids. The results indicate a more considerable thickening of the viscous sublayer in the turbulent pipe flow of the test solutions than that of Newtonian fluids.

The interface of a structural system in the soil is usually unsaturated. A decrease in the shear strength of the soil-structure interface can degrade the structure, especially under humid conditions. Studying the shear characteristics of the silt-concrete interface using a shear apparatus. Suction-controlled ring shear tests were carried out on the silt-concrete interface for three interface roughness values. The influence of the matric suction (s) and interface roughness (R) on the shear strength index of the silt-concrete interface was analyzed. The test results showed that high values of s and R improved the shear strength of the interface, but the result was affected by the net normal stress (NNS). High values of NNS and R improved the strain-hardening characteristics. NNS, s, and R significantly affected the interface shear shrinkage. The internal friction angle of the saturated interface was smaller than that of saturated silt, whereas the opposite occurred in the unsaturated state. The cohesion and internal friction angle of the interface rose with an increase in R, and they were larger than that of silt. A shear strength model of the silt and interface was established.

The application of space robotic manipulators and heightened autonomy for ios represents a paramount pursuit for leading space agencies, given the substantial threat posed by space debris to operational satellites and forthcoming space endeavors. This work presents a guidance algorithm based on drl to solve for the space manipulator path-planning during the motion synchronization phase with the mission target. The goal is the trajectory generation and control of a spacecraft equipped with a 7-dof robotic manipulator, such that its end effector remains stationary with respect to the target point of capture. The ppo drl algorithm is used to optimize the manipulator’s guidance law, and the autonomous agent generates the desired joints rates of the robotic arm, which are then integrated and passed to a model-based feedback linearization controller. The agent is first trained to optimize its guidance policy and then tested extensively to validate the results against a simulated environment representing the motion synchronization scenario of an ios mission.

The acoustic environment in learning spaces significantly influences learning effectiveness and occupant well-being. Recent studies have shown that a series of architectural factors within physical learning environments can impact students' educational experiences. This research delves into the relationship between architectural characteristics and the perceived acoustic environment among 467 primary students in 19 learning spaces across 9 schools in Chile. The survey comprises a student questionnaire, a checklist evaluating space characteristics, and acoustic measurements of indoor noise levels during occupied conditions. Examined topics include Indoor Environmental Quality (IEQ) comfort perception, noise annoyance, hearing ability, and acoustic preference. Architectural characteristics considered encompass flexible and acoustic space design parameters. The results indicated that noise discomfort was a common issue, especially in traditional learning spaces without acoustic treatment. The type of learning space (traditional or flexible settings) has a greater impact on acoustic perception particularly concerning noise discomfort and acoustic preference. However, poorly acoustic spaces lacking absorbing materials or exhibiting lower spatial density (m2 per student) contribute to increased indoor noise levels affecting noise annoyance caused by children's talking inside. The study emphasizes the importance of considering both architectural design and acoustic conditioning for optimizing the acoustic experience in educational spaces.

The incessant evolution of online platforms has ushered in a multitude of shopping modalities. Within the food industry, however, assessing the delectability of meals can only be tentatively determined based on consumer feedback encompassing aspects such as taste, pricing, packaging, service quality, delivery timeliness, hygiene standards, and environmental considerations. Traditional text data mining techniques primarily focus on consumers' emotional traits, disregarding pertinent information pertaining to the online products themselves. In light of these aforementioned issues in current research methodologies, this paper introduces the Bert BiGRU Softmax model combined with multimodal features to enhance the efficacy of sentiment classification in data analysis. Comparative experiments conducted using existing data demonstrate that the accuracy rate of the model employed in this study reaches 90.9%. In comparison to single models or combinations of three models with the highest accuracy rate of 7.7%, the proposed model exhibits superior accuracy and proves highly applicable to online reviews.

Background and Objectives: The purpose of this study was to investigate whether early surfactant administration affects the status of ductus arteriosus (DA) in preterm infants ≤32 weeks of gestational age (GA) within 24 hours of birth. Materials and Methods: It is a prospective study conducted from March 15, 2022, to November 15, 2023, in a tertiary academic center. In-born infants ≤ 32 weeks of gestation (n = 88) were enrolled. The study group was further divided into surfactant (n=44) and non-surfactant (n=44) subgroups. Results: 76% of the preterm infants who received surfactant therapy (RRR = 0.839) recorded an increase in Kindler Score at 24 hours of life (1-RR = 1-0.24 = 76%). Surfactant administration was significantly associated with decreased pre-ductal diastolic pressure (29.9 mmHg vs. 34.8 mmHg, p=0.0231), post-ductal diastolic pressure (28.7 mmHg vs. 32.2 mmHg, p=0.0178) pre-ductal MAP (41.6 mmHg vs. 46.5 mmHg, p=0.0210) post-ductal MAP (41.0 mmHg vs. 45.3 mmHg, p=0.0336). There were no significant changes in ductus arteriosus parameters at 24 hours of life. Conclusions: Early surfactant administration does not affect the status of ductus arteriosus in preterm infants ≤32 weeks of gestational age at 24 hours of life.
